Chapter Text

By the time Belphegor told him to take his robe off for the third time, Lucifer had decided that dying might have been less humiliating.

“Absolutely not,” he said, with enough offended dignity to suggest he had not, in fact, already removed it twice that afternoon. He sat on the edge of the bed with one hand braced against the mattress and the other clutching the front of his dressing gown closed over his chest, though the gesture lost some of its authority on account of the dressing gown being yellow, covered in tiny embroidered ducks, and slipping steadily off one shoulder. “You have inspected me. Extensively. I would even go so far as to say intrusively. At this point I’m beginning to suspect you’re looking for a second, smaller Lucifer hidden inside me.“

Bel did not look up immediately. She finished whatever she was recording on the slim medical tablet balanced across one knee, set it aside on the bedside table, then reached for the small collection of gauze, tape and antiseptic she had arranged there earlier.

“The dressing on your left side needs changing.”

Lucifer glanced down as though the offending bandage had personally betrayed him. Beneath the loose fold of his dressing gown, white gauze wrapped the worst of his ribs, its edges beginning to lift where movement and several hours of stubborn refusal to remain properly at rest had worked at the adhesive.

“It looks perfectly serviceable.”

“There’s blood coming through it.”

He looked again.

A small patch of gold had indeed begun to seep through the gauze, bright enough now that pretending it was anything else would require considerably more creativity than he currently possessed.

“That,” Lucifer said, after a moment’s consideration, “could be anything.”

Bel regarded him with the unhurried stillness peculiar to her, a quiet that seemed to soften the edges of everything around it. There had always been something faintly dreamlike about Bel, as though some part of her remained suspended in that warm, heavy place just before sleep, where movement became optional and time lost its insistence. It could make her appear languid to anyone who did not know her. Lucifer knew better. Very little escaped her attention. She simply saw no reason to hurry towards conclusions that would still be there when she arrived. “It could be,” she said. “Statistically, it’s probably your blood. The cuts over the fractures were deep. I need to make sure they’ve closed properly.”

“They have,” Lucifer said with the brittle certainty of someone who had decided the matter several hours ago and saw no compelling reason for his body to contradict him. His fingers tightened briefly around the edge of his dressing gown, keeping it firmly closed. “Completely healed. Miraculous recovery. Very inspiring.”

“You haven’t looked.”

“I have an excellent intuitive relationship with my own torso.”

Bel picked up a fresh dressing and waited.

Lucifer held her stare for several seconds, already assembling the argument he ought to have made. There should have been outrage in it, something grand about the indignity of being peeled apart and repackaged like damaged merchandise. Ordinarily he could have kept the performance alive until she threatened to sedate him.

Tonight, merely imagining the effort made him tired.

His shoulders sank by a fraction.

“Oh, fine.” He loosened his grip on the dressing gown and let the fabric fall open, irritation lingering where the argument had already run out of strength. “But this is the last time. Whatever you find under there, we’re committing to it.”

Bel reached for the medical tape. “You can consider it the last time once I’m satisfied the wound has closed.”

Lucifer’s mouth tightened. Normally, Bel’s complete refusal to rise to him would have been invitation enough to try harder; he could have worried at that serene, infuriating composure for as long as it took to coax so much as an irritated twitch from her. But again, the sharper remark formed and went nowhere. He could already hear how it ought to sound, could feel the familiar instinct to turn annoyance into something larger and brighter and considerably more entertaining, but somewhere between thinking it and speaking it, the effort required became disproportionate to the reward. He let the moment pass, then found himself irritated by that too.

The room had become too warm sometime during the examination. One of the curtains had been left half open, allowing the bruised violet of Hell’s evening sky to fall across the carpet and the abandoned mess of his things, a tipped stack of paper, three half-finished duck designs, an untouched cup of tea gone cold. His jacket lay over the back of a chair because Charlie had insisted he stop wearing it while his wounds healed. He had agreed after informing her, at length, that this constituted an attack on his right to look fabulous in her hotel.

He had not put it back on since.

Bel reached for the belt of his dressing gown, and Lucifer caught her wrist before he had consciously registered what she was doing. The movement was startlingly quick, his fingers closing around her before either of them had spoken, and Bel simply stopped where she was, making no attempt to pull away as the quiet stretched between them.

Lucifer became aware of his own grip in stages: fingers tight around her wrist, pulse hard beneath his thumb, shoulders drawn high enough to pull against the healing bruises scattered along his back. Somewhere beneath his ribs, something ugly and electric had already begun shouting that he had been touched without warning, that he had failed to see it coming, that the room was too small and someone was standing too close and he needed to move before movement stopped being an option.

Then Bel said, very evenly, “I was going to check the gauze.”

He released her at once.

“Right.” He rubbed his palm against his thigh as though that could erase the reflex. “Obviously. Which I knew. Because I am famously excellent at context.”

Bel adjusted her sleeve without comment, neither reassuring him nor asking what had prompted the reaction, and simply stepped back far enough to give him space before waiting for him to decide what happened next.

That made it worse somehow.

Lucifer looked towards the window. “You can go ahead.”

“Do you want me to?”

He hated the question enough that it almost steadied him.

“Yes, Bel, you may examine the wounds you have already examined twice, before they undergo some dramatic new development while unattended.”

Bel gave him another moment before nodding, and when she reached for the dressing gown again, her movements remained deliberately unhurried. “I’m going to move this aside now.” Lucifer managed a faint grimace at the unnecessary warning, though he offered no objection this time, allowing her to ease the fabric away from his side.

Bel worked one edge of the dressing loose and peeled it carefully away from his side, pausing where dried blood had caught the gauze against his skin rather than pulling through it. The stain Lucifer had noticed from the outside had spread farther beneath the bandage, enough to justify Bel’s concern, though once the last of the gauze came free there was no fresh blood waiting beneath it. The cuts themselves had closed. Thin, angry seams remained across the damaged skin above his ribs, tender and newly knitted, with traces of dried blood marking where they must have seeped sometime earlier before finally sealing.

Lucifer looked down and immediately acquired the expression of a man whose vindication had arrived under exceptionally trying circumstances. “They have closed.”

Bel continued cleaning the dried blood from his side. “Good.”

The bruising beneath the wounds had changed colour over the past few hours, black and purple beginning to give way at the edges to the sickly yellow-green of healing, though the deeper marks remained dark where cables and restraints had dug in. His body was repairing itself with the unnatural speed of angelic flesh, closing wounds that would have kept a sinner bedridden for considerably longer, but apparently divinity had done nothing so useful as make healing painless. Every turn taken too quickly still pulled at his ribs; laughing hurt, coughing was worse, and reaching for anything beyond comfortable arm’s length had become an unexpectedly elaborate negotiation with his own body.

Bel discarded the bloodied gauze and examined the newly closed cuts before pressing two fingers lightly beneath the lowest bruise, feeling along the line of the rib before moving higher. Lucifer endured the first few touches with his jaw set and one hand clenched in the bedding beside him, but when her thumb found the damaged rib and applied even slight pressure, pain drove sharply through his side and a vicious hiss escaped between his teeth.

“Fuck, Bel.”

She eased the pressure without immediately taking her hand away. “There?”

“Where the fucking broken rib is? Yes, there.” The irritation came out harder than he intended, stripped of most of the theatrical polish he usually wrapped around it, but Bel neither reacted nor apologised. She simply shifted her fingers and continued examining the surrounding tissue, slow enough that he knew exactly where she was going next. Lucifer braced himself, shoulders rigid, managing one probing touch and then another before she pressed closer to the fracture and his hand snapped around her wrist.

“Enough.”

Bel stopped immediately.

For several seconds Lucifer remained hunched slightly around his injured side, still holding her wrist as the pain worked its way back down from something bright and nauseating into the persistent ache he had become accustomed to. When he realised what he was doing, his fingers loosened and fell away.

Bel reached for the tablet only after he had released her. “Pain scale?”

Lucifer gave her a sharp look. “Compared to what?”

“Your normal baseline.”

He shifted carefully upright, one palm pressed protectively against his side. “Compared to what, Bel? Falling from Heaven? Because against that, this is fucking delightful.”

Bel’s expression remained placid. “Compared to the a pain you can reasonably remember.”

That silenced him for a moment. There were, inconveniently, few contenders.

“Five,” he said at last, then added with a trace of resentment, “when you stick your fingers into it.”

“And at rest?”

Lucifer hesitated. “Three.”

Bel returned to the tablet and began adding the results of the examination to whatever she had already recorded there, occasionally pausing to scroll through something before entering another note. Lucifer watched her for the first minute or so, still holding the dressing gown closed across his freshly healed side, waiting for some indication that they were finished. None came.

The silence stretched.

He shifted against the edge of the mattress and immediately regretted it when the movement pulled at his ribs, though the pain settled quickly enough once he stopped moving. Bel continued working. A few taps against the screen, a pause, then more scrolling. Lucifer could not tell whether she was reviewing what she had just found or comparing it against something else, and the longer she remained absorbed in it, the more conscious he became of sitting there waiting to be assessed.

He disliked that feeling.

There was something about being observed while someone else decided what his body meant that had become considerably harder to tolerate than it used to be.

His bare hoof began moving against the carpet, heel lifting and falling in a restless little rhythm before he noticed and forced it still. He looked towards the window instead, then at the abandoned cup on the bedside table, then eventually down at his own hands. The adrenaline from having his ribs examined was already draining away, leaving the familiar exhaustion beneath it, heavy enough that his thoughts began to loosen despite the tension still held through his shoulders.

For a while, the room blurred pleasantly at the edges. He was not asleep. He would have objected strongly to any suggestion that he had been asleep. He was simply resting his eyes.

When Lucifer surfaced again, Bel was no longer looking at the tablet.

She was watching him.

Her usual languor remained, that strange dreamlike stillness that made it seem as though nothing in creation could persuade Belphegor to move faster than she intended, but there was a concentration beneath it now that made Lucifer’s skin prickle. Her attention travelled over the way he sat, the tension still caught in his shoulders, the hand resting protectively across his ribs, and then lingered on his face with the quiet appraisal of someone adding another finding to an already troubling list.

Lucifer straightened. “What?”

When Bel did not answer immediately, his irritation sharpened. “What are you looking at?”

“You.”

She glanced back at the tablet, then at him again.

Lucifer’s fingers tightened around the edge of his robe. “Don’t do that.”

“Do what?”

“That.” He gestured vaguely between her face and the screen. “Whatever deeply concerning medical calculation is happening in there. Either say it or stop looking at me like you’ve found something.”

Lucifer stared at her, waiting. When nothing followed, his brows climbed, one hand turning upwards in an increasingly impatient demand for any answer but she just continued scrolling.

A small, incredulous noise escaped him.

Still nothing.

His hand dropped back into his lap with an irritated slap.

The silence that settled after that was not especially dramatic. Lucifer would have preferred if it had been. Drama provided structure. Drama came with music, staging, a decent entrance and, ideally, pyrotechnics. This was only the faint scratch of Bel’s thumb against glass and the distant sound of someone downstairs dropping something metallic in the kitchen, followed by Husk swearing loud enough to travel through floors and closed doors.

Bel allowed his irritation to settle before returning to the tablet. “Your sleep has deteriorated considerably. Your resting heart rate is elevated, your cortisol has remained above baseline, and there are signs of sustained appetite suppression.”

Lucifer’s mouth opened somewhere around resting heart rate, an objection already forming, but Bel continued with the same unhurried precision, giving him nowhere useful to insert it. By the time she reached his appetite, he had settled for a low, disgruntled sound and pulled the dressing gown more securely around himself.

“I ate yesterday.”

Bel’s thumb paused against the screen.

“Toast,” he added, because apparently that mattered now. When she still said nothing, he shifted beneath the weight of her silence and muttered, “It was a perfectly respectable amount of toast.”

Bel raised her head then, and Lucifer immediately disliked whatever she saw. There was no accusation in her expression, no pity either, only that quiet clinical attention which seemed capable of stripping every carefully arranged excuse down to the inconvenient thing beneath it.

He summoned a smile anyway, bright and effortless by long practice, and held it there as though this alone might demonstrate that the King of Hell was in excellent health and everyone could kindly stop taking measurements.

Bel watched him.

The smile lasted several seconds before the effort of maintaining it began to feel absurd. It faded at the corners first, then disappeared altogether, leaving Lucifer tired, sore and increasingly aggravated that she had managed to dismantle the performance without saying a word.

“Oh, for fuck’s sake, Bel,” he muttered, turning his face away.

He pushed himself backwards on the bed, intending to lean against the headboard, misjudged the movement, and hissed when his ribs objected. Bel’s hand twitched towards him and stopped before she reached.

Lucifer noticed the aborted movement and wished, with a sudden flare of irritation, that he could stop noticing every careful adjustment people made around him. He drew the dressing gown across his bare side, covering the newly closed cuts and the ugly spread of bruising beneath them. “I’m healing,” he said, with more insistence than the statement required.

“Physically,” Belphegor corrected.

His jaw tightened. “Yes, thank you. Generally the category doctors concern themselves with.”

Belphegor returned her attention to the tablet. “You know that isn’t true.”

Whatever answer Lucifer might have given remained caught behind his teeth.

He could have made a joke there. There were several available. He could have accused her of practising psychology without a licence, suggested she prescribe him a nap and save everyone the trouble, demanded that she return to Sloth and leave him to his extremely dignified convalescence.

Instead, whatever argument had been gathering behind Lucifer’s teeth dissolved into a tired exhale. “I’m tired.”

Something in Belphegor’s expression softened, so subtly that he might have missed it if he had not spent several millennia learning the small shifts beneath her perpetual languor. She set the tablet aside and rose, reaching behind him to pull the pillows higher against the headboard before resting a hand lightly against his shoulder.

“Lean back.”

Lucifer made a faint sound of objection, more habit than conviction, but allowed her to guide him against the pillows. The change in position took some of the strain from his ribs almost immediately, his body betraying him with a long exhale as his weight settled into the mattress. Bel adjusted one of the pillows behind his side until he could rest without twisting across the fractures, then drew the discarded edge of the duvet loosely over his legs.

“Sleep will clear some of the remaining physical strain faster than anything I can give you,” she said as she worked, her voice carrying the same quiet clinical certainty with which she might have discussed medication. “Your body has already done most of the difficult work. The wounds have closed, the fractures are knitting, and the inflammation is coming down. It needs rest now, preferably more than two or three broken hours at a time.”

Lucifer’s mouth tightened at the accuracy of the number, though he lacked the energy to ask how she had arrived at it. He shifted deeper into the pillows instead, one hand settling carefully over his bruised ribs.

Belphegor watched the movement before adding, quieter, “Being tired after what your body has been through is expected.”

There was enough room in the statement for Lucifer to accept it as medical fact rather than consolation, which was perhaps why he did not immediately fight her on it.

He meant only to close his eyes for a bit.

At some point Bel returned to the chair, or perhaps she had never left it. Lucifer could not remember. The room remained warm around him, her movements sparse and quiet enough to disappear beneath the soft drag of exhaustion, and when he tried to follow the thought he had been having, it slipped somewhere beyond his reach. His hand loosened over his ribs. The tension in his shoulders followed more reluctantly, giving way by degrees as his body sank deeper into the pillows, until even the awareness of Belphegor somewhere nearby ceased to require his attention when he fell into a deep exhausted sleep.

When consciousness found him again, it did so without urgency. For several moments Lucifer remained caught in the heavy confusion of waking somewhere familiar and still needing time to understand why. The room had changed around him. What little light had been coming through the curtains was gone, replaced by the low amber lamps along the walls, and his mouth was dry enough that swallowing felt unpleasant. His ribs still hurt, though the pain had settled into something deeper and duller, no longer sharpened by every breath.

Bel’s chair was empty.

Lucifer found her on the other side of the room, moving slowly along the shelves Charlie had insisted he needed when he first began staying at the Hotel. They had filled surprisingly quickly in the months since. Books had migrated over from the palace in uneven stacks, accompanied by tools and half-built mechanisms, photographs he had brought across in batches rather than all at once, and, inevitably, enough ducks to occupy whatever space remained. There was still something temporary about parts of the room, boxes tucked beneath a table that he had never quite unpacked, bare stretches of wall waiting for him to decide what belonged there, but the shelves had begun to look unmistakably lived in.

Belphegor appeared to be examining the evidence of that process with mild interest, touching very little as she wandered.

Then she stopped.

One shelf was less chaotic than the others. A photograph of Charlie stood there in a small gold frame, beside a handful of things Lucifer had chosen to bring from the palace almost immediately rather than allowing them to disappear into one of the boxes. Among them sat a small stuffed Belphegor.

The toy was relatively new, one of Belphegor’s more recent gifts, its fabric still soft and its ridiculous little likeness of her largely untouched by wear. What caught the attention was where Lucifer had put it. It had not disappeared amongst the growing population of ducks or been abandoned in one of the half-unpacked boxes around the room. He had given it a place beside Charlie’s photograph, carefully positioned on one of the few stretches of shelf he seemed to have arranged with any real intention. There was nothing accidental about it being there.

Lucifer watched from the bed as Bel reached for it, she lifted the little likeness of herself from its place, her thumb passing once over the seams. For a moment he expected her to say something about it, perhaps ask why he still had it, but she remained quiet.

Then, almost absently, she drew it against herself.

Her arms folded around it loosely at first. A moment later her fingers pressed deeper into the soft fabric.

Lucifer’s stomach tightened.

Belphegor had always carried stillness around her as though it were part of her domain, something deep and soporific that could make even concern appear languid from the outside. He saw the slight curl of her shoulders now, the way her hand remained closed around the toy she had given him not long ago, and understood with an uncomfortable immediacy that she was holding herself together, too.

He had not been meant to see this.

Perhaps that was why shame came so quickly.

After years of unanswered calls and abandoned invitations, after allowing silence to grow between himself and the Sins until it had become easier to pretend there was nothing left to cross, he had kept her gift. More than kept it. When he had finally begun moving pieces of his life into the Hotel, deciding one object at a time what deserved to follow him out of the palace, he had also chosen this to stay.

He had put her somewhere he could see her.

And still he had never called.

Lucifer turned his face away, attention dropping to the folds of the duvet as though there might be something there worth studying. He shifted without meaning to, and the movement pulled unpleasantly through his ribs, drawing a low sound from the back of his throat.

Across the room, Belphegor stirred. By the time he looked towards her again, the plush had been returned carefully to its place beside Charlie’s photograph. Bel rested two fingers against its head for a moment, adjusting it until it sat properly, before turning towards the bed.

“You’re awake.”

Lucifer cleared the sleep from his throat. “Apparently.”

Bel crossed back towards him, and there was something easier in her movements now, subtle enough that he might have imagined it. She poured water from the carafe beside his bed and handed him the glass before checking the time.

“You slept nearly eleven hours.”

Lucifer stopped halfway through his first drink.

His expression must have been sufficiently eloquent because Belphegor’s mouth softened at one corner, the closest she had come to looking openly pleased all day.

“That’s good,” she said. “That’s the first full day’s sleep you’ve managed in some time.”

Lucifer lowered the glass slowly and looked towards the darkened window, trying to reconcile the few blurred moments he remembered with an entire day having disappeared around him.

Eleven hours.

He could not remember the last time sleep had taken him that completely.

His attention drifted back towards the shelf.

The little Belphegor sat exactly where he had left her, except now she was angled slightly towards the bed.

Bel seemed content to let him sit with that for a moment, and Lucifer was beginning to entertain the possibility that eleven hours of unconsciousness had finally earned him release from medical supervision when she retrieved the tablet.

“The sleep is encouraging,” she said. “So is the physical healing. Your readings over the last few months still concern me.”

Lucifer, halfway through another drink, lowered the glass. He had heard the rest of it. Unfortunately, one word had rather eclipsed everything surrounding it.

“Months?”

Belphegor’s thumb moved across the screen, bringing up something that looked considerably more extensive than the notes she had taken that afternoon. “There’s been a sustained decline across several markers. It becomes more pronounced recently, but the pattern predates the recent incident.”

Lucifer’s attention fixed on the tablet, where graphs crowded the display alongside a troubling number of dates, far more of them than anything Belphegor had done today could possibly account for, and after several seconds of increasingly suspicious study, he set the water down very carefully.

A crease appeared between Lucifer’s brows as Bel returned her attention to the data, apparently expecting that to settle the matter, and his hand slowly lowered as he looked back at the tablet and understanding began to set in. “How,” he asked, with remarkable restraint, “do you have readings from months ago?”

Belphegor’s thumb stopped against the screen, and for once her composure shifted, only slightly, her gaze dropping to the tablet with something that came remarkably close to sheepishness. It lasted just long enough for Lucifer’s confusion to sharpen into alarm before she seemed to decide there was little point disguising it now. “I’ve been monitoring your health.”

Lucifer went very still. His eyes moved from Bel to the tablet and back again, mouth parting as the full implication worked its way through the last remnants of sleep. The graphs, the dates, her irritatingly precise knowledge of how little he had been sleeping, all of it rearranged itself into something far more invasive than an overenthusiastic medical examination.

Belphegor, apparently accepting that there was no version of this conversation in which she emerged entirely innocent, gave a small lift of one shoulder and returned to the screen.

Lucifer stared at her in mounting disbelief. “For how long?”

The faint sheepishness returned. Bel considered the question for a moment, then scrolled upwards.

The fact that she needed to check was significantly worse than any answer he had been expecting.

“Intermittently,” Belphegor said at last. “For several hundred years.”

Lucifer sat upright so abruptly that pain tore across his ribs, sharp enough to blanch the outrage from his face for half a second. His hand flew to his side, but whatever instinct might ordinarily have made him retreat from the pain was thoroughly overwhelmed by what she had just said. “You have been what?”

With a brief look that suggested she knew perfectly well he had heard her, Bel rose from the chair and took his half-empty glass from the bedside table. “Monitoring your health.”

He watched her walk away with the glass, disbelief following her across the room. There was something uniquely maddening about receiving this information while Belphegor calmly busied herself with the ordinary business of keeping him alive, emptying the stale water into the basin and refilling the glass from the carafe as though she had not just admitted to several years of covert medical surveillance.

“I heard you.” His voice climbed despite himself. “I was hoping you might hear yourself and realise how completely fucking insane that sounds.”

Carrying the fresh water back, Bel refrained from handing it to him while he was sitting rigid enough to aggravate every injury she had spent the day examining, instead placing it within reach on the bedside table. A pointed glance at his posture followed before she crossed to the window and eased it open, allowing cooler air to slip into the room, stir the curtains and clear some of the warmth that had accumulated during his long sleep.

“You have been medically spying on me for years.” Lucifer’s attention followed her across the room.

“I’ve been keeping an eye on a limited set of health markers,” Belphegor said, adjusting the window until the opening satisfied her. There was still the faintest trace of sheepishness about her, visible mostly in the fact that she had yet to look directly at him, though it did nothing whatsoever to soften the certainty in her voice. She knew she should not have the information. She also appeared to have decided that embarrassment over the method ranked considerably below whatever the information itself had told her.

“That is medical spying.” He stared at her back, appalled.

Bel watched him with the detached patience of a being who had once sat through a six-hour argument between Mammon and Leviathan about whether stealing someone’s casino counted as theft if they had technically left it unattended.

Lucifer pushed himself to his feet, evidently deciding that this conversation required considerably more vertical authority than the bed allowed him. The effect lasted perhaps two seconds before the room tilted beneath him and he caught the bedpost with one hand, fingers closing hard around the wood until the dizziness passed. Belphegor noticed. Of course she noticed. She simply had the decency to occupy herself with adjusting the curtains rather than acknowledging it, which made the entire thing more humiliating.

He straightened with what dignity remained available to him. “Several years. Without telling me.”

“You did know.” Bel turned from the window and, before he could begin the objection already gathering across his face, continued. “You consented to long-term monitoring after the last incident in 1447. I suggested it because you had been unconscious for almost nine hours by the time I found you, and I had no reliable way of knowing what had happened or whether there was an underlying condition that required treatment.”

Lucifer’s expression shifted at the date, recognition arriving without anything resembling agreement. “I was drunk.”

“You were unconscious,” Belphegor added, crossing back towards the bedside table to retrieve her tablet. “Which is why I waited until you woke up before examining or treating you. You hadn’t given me permission, and there was no immediate indication that intervention was necessary.”

Lucifer’s mouth opened.

Bel kept going.

“Three days later, when you were conscious, coherent and sufficiently irritated with me to demonstrate reasonable decision-making capacity, I explained the monitoring, gave you the consent form and told you what information it would collect. You signed it.” By the time Bel finished, his raised hand had become less an attempt to speak and more a physical manifestation of outrage.

“You cannot possibly,” he began, gathering himself with visible effort, “be invoking a piece of paper I signed in fourteen-fucking-forty-seven as justification for spying on me now.”

Belphegor glanced down at the tablet. “You never revoked it.”

There were several centuries of legal, moral and deeply personal objections competing for expression, and for once even he appeared unable to decide which deserved to escape first until frustration finally selected the simplest one. “Well, I should have.”

“I can revoke it now for you.”

“Yes. Obviously. Revoke it.”

Belphegor tapped the screen.

“Done.”

Some of the momentum went out of him so abruptly that his prepared indignation seemed to lose its footing. He had expected resistance, or at the very least one of Bel’s maddeningly clinical explanations for why continued access was in his best interests. Instead, she had simply removed it.

Bel set the tablet down. “I won’t receive anything further.”

Lucifer remained beside the bedpost, still visibly angry, though the shape of that anger had become harder to maintain now that she was no longer giving him anything to push against. After a moment his attention drifted back to the tablet.

“And everything you already have?”

Belphegor regarded him quietly. “I can delete that too.”

His answer should have been immediate, but it wasn’t.

“No,” he said eventually, irritation creeping in as Belphegor’s silence made the hesitation feel considerably more revealing than he would have liked. “You already have it.” Her expression remained infuriatingly neutral, and Lucifer scowled. “Don’t look at me like that.”

He sat down again, slower this time, and adjusted the robe around his knees. “Why were you even checking?”

Bel’s fingers settled against the edge of the tablet, but Lucifer continued before she could answer.

“I haven’t spoken to you properly in years.”

The admission lingered between them, and when Belphegor did not immediately answer, Lucifer’s gaze dropped to where the belt of his robe had twisted around his fingers. He unwound it slowly, only to wind it around them again.

There had always been reasons. At first he had been busy, then embarrassed, then tired, and eventually so much time had passed that every unanswered message became another small piece of evidence that he had left it too long. Calls were dismissed with the intention of returning them later, invitations remained unopened until the dates had passed, and the little flashes of magic announcing someone trying to reach him became easier to ignore once he had grown accustomed to pretending he had not seen them. There had been entire decades in which he had missed them with an ache he refused to examine too closely, and still he had done nothing about it.

Belphegor watched his fingers worry at the fabric for a while before answering. “That’s why I kept checking.”

Lucifer’s hands stilled.

“You withdrew. Then you stopped answering often enough that I couldn’t tell whether you were avoiding us or whether something was wrong.” Bel’s voice remained quiet and measured, clinical in its restraint even as something more personal sat beneath it. “I knew you weren’t going to tell me if you were unwell, and I was worried about you. The readings were the only way I had left to know you were still all right.”

He gave a quiet laugh that contained no amusement at all.

“I’m a busy guy.”

It sounded weak even to him.

Belphegor did not dignify it with an answer, and in the quiet that followed Lucifer found himself staring down at the robe gathered between his fingers, wishing she had. An argument he could have handled. He could have defended himself against accusation, found some technicality to wedge beneath it and pry until the whole uncomfortable conversation came apart. Silence left him with nothing except the years themselves.

There had been a time when busy might even have been true.

Charlie had arrived and, for a while, everything else had become wonderfully irrelevant. He remembered the impossible smallness of her, the terror of holding something he loved that completely, days and nights collapsing into one another until time was measured in feeds and crying and the rare miraculous stretches when she slept against his chest. He remembered sleeping badly even then, waking at the slightest sound from her cot, checking on her more often than was probably reasonable, and the growing reluctance to let her too far out of his reach.

Somewhere amongst all of it Lilith had begun drawing away from him. Or perhaps he had withdrawn first. He could no longer remember where one movement had ended and the other began, only that she had worried about him, that everyone had worried about him, and that eventually he had stopped trusting his own judgement enough to argue when they told him what was best. After that came the stretches of cold civility between them, Charlie growing old enough to notice when her parents stopped speaking as soon as she entered the room.

Then there had been his own mind to contend with.

Some years were worse than others. Some disappeared almost entirely beneath a weight he had never found a useful name for, days when leaving his rooms required more effort than he possessed and answering a call felt like an obligation he could postpone until tomorrow. Tomorrow became next week with astonishing ease. The Sins had known him too long, which had somehow made them harder to face. They would notice. They would ask. They might come anyway. So he became very good at being unavailable.

When Lilith left for good, even the pretence of being busy became difficult to sustain.

The palace grew quiet around him. Charlie had her own life, as she should, and Lucifer discovered how little remained of his once everyone else had somewhere else to be. He made things. He filled rooms with projects, abandoned half of them, started more. He let calls ring unanswered while promising himself he would return them when he felt more like himself, without ever deciding what that was supposed to mean.

Then Charlie had called about the Hotel.

For the first time in years there had been somewhere he was needed, even if he had nearly ruined that too. The Hotel had brought people and noise and purpose crashing back into his life, along with an extermination, a dead angel, a destroyed building and enough blood to remind him exactly what happened when Heaven decided Hell required correction. He had stood in the aftermath with Charlie alive and still somehow found ways to blame himself for every moment she had not been safe.

And then Vox happened.

Lucifer’s fingers tightened around the belt of his robe.

His mind did not need help supplying what came next. It offered fragments anyway, quick and unwanted: restraints biting into his burned skin, the helpless awareness of being watched, the sickening certainty that whatever happened next belonged entirely to someone else. He felt again the particular humiliation of discovering that power meant very little once someone had found the right way to take it from him. Drain it.

Afterwards, people had asked whether he was all right.

He had lied.

Of course he had lied.

The realisation settled heavily because, somewhere beneath all the excuses, Bel had been right about one thing. If she had called him at any point during those years and asked whether something was wrong, Lucifer knew exactly what he would have said.

Nothing.

Nothing was wrong. He was busy. He was tired. He would call tomorrow.

Belphegor’s voice drew him back into the room.

“We’re family, Lucifer.”

His fingers stopped moving.

Bel had not raised her voice. There was no lecture waiting behind the words, no demand that he account for every missed call or explain why he had made himself increasingly impossible to reach. She sat with the same unhurried stillness she carried everywhere, watching him with an exhaustion that suddenly looked older than the hours she had spent beside his bed.

“You don’t have to be well before you’re allowed to come back to us.”

Lucifer said nothing to that. Belphegor seemed content to leave the words where they had fallen, without asking him to accept them or offer anything in return, and after a while she reached for the tablet again, granting him the small mercy of something clinical to look at instead of her.

“I have your bloodwork too.”

Lucifer dragged a hand over his face. “Threatening me with pathology results now. Wonderful. Very nurturing.”

The heaviness did not disappear, but something in it loosened enough for the familiar dryness to find its way back into his voice, and Bel allowed the remark to pass without pointing out that he sounded marginally more like himself. Instead, she drew two fingers across the tablet and flicked them upwards.

Light unfolded above it.

Lucifer recoiled slightly as a translucent display expanded between them, throwing pale lines across the dim room. Months of data arranged themselves into layered graphs, dates running along the bottom while several coloured traces climbed, dipped and occasionally spiked with enough complexity to make his eyes narrow.

Belphegor rose and moved around the projection, enlarging one section with a slow movement of her hand. “Your recent results concern me. They’re consistent with what I’ve already seen clinically: prolonged stress, disrupted sleep, reduced appetite and a baseline that has been moving in the wrong direction for some time.” Her fingers travelled further back through the data, compressing weeks into months until the overall decline became unpleasantly obvious. “But that isn’t the only pattern.”

Lucifer had intended to remain unimpressed. Unfortunately, there was something deeply compelling about being presented with an enormous glowing diagram of himself, and within moments he had shifted towards the edge of the bed to see it better.

Bel isolated several points along the timeline.

Against the broader downward trend, a handful of sharp rises stood out.

Lucifer frowned. “What are those?”

“That,” Bel said, indicating the first cluster, “is what I’ve been trying to understand.”

She expanded it, and several additional measurements appeared alongside the original graph. “They’re positive anomalies. Your resting heart rate stabilises, stress markers fall more quickly after elevation, appetite improves, and there are measurable changes in several endocrine indicators associated with mood and social engagement. They don’t last indefinitely, but they recur often enough, and consistently enough, that I stopped treating them as noise.”

Lucifer’s suspicion gave way, reluctantly, to interest. He leaned closer to the hologram, following one of the peaks as though staring hard enough might reveal whatever humiliating secret his own biology had apparently been keeping from him.

“So somewhere in the middle of my catastrophic decline,” he said, gesturing towards the considerably less flattering majority of the graph, “my body occasionally decides to have a lovely time without informing me.”

Belphegor’s mouth shifted faintly. “Essentially.”

She enlarged the anomalies further.

Lucifer watched several dates separate themselves from the surrounding data, his amusement beginning to fade beneath genuine curiosity. “What causes them?”

Bel’s gaze moved from the hologram to him.

“I have a hypothesis.”

Belphegor left it there for a moment, rearranging the projection until the individual anomalies sat above a longer stretch of Lucifer’s declining baseline. There were more of them than he had initially realised. Some were brief, little more than a few hours of measurable improvement before the lines settled back towards their usual course, while others appeared to linger for a day or two. Lucifer found himself leaning closer, irritation temporarily displaced by the much stronger compulsion to solve whatever his own body had apparently been doing behind his back.

Bel began with the obvious possibilities. Charlie accounted for some improvement, particularly around periods when Lucifer had spent sustained time with her, but the correlation was too broad and the timing inconsistent. The Hotel itself produced similar problems. Moving in had altered his baseline enough to be measurable, as had becoming more involved in Charlie’s work, but neither explained the isolated peaks appearing within it.

Lucifer considered this with unexpected seriousness, one hand moving through the hologram as he traced several dates. “Food?”

“I checked.”

“Alcohol?”

“Mostly negative.”

He looked faintly offended by that.

Bel continued before he could defend the therapeutic merits of a good bottle of wine. Sleep had been considered and largely eliminated as a cause because, irritatingly, improved sleep appeared more often after the anomalies than before them. Major successes occasionally produced the expected response, although several of the largest spikes occurred on days when Lucifer had accomplished nothing Bel could identify as particularly significant. Exercise was inconsistent. Magic use pushed several markers in the wrong direction. Sexual activity produced changes that were both obvious and physiologically distinct enough to remove from the comparison.

Lucifer’s head snapped towards her. “I’m not having any sex.”

For the first time in several minutes, Belphegor looked away from the hologram. “Masturbation counts.”

Colour rose immediately into Lucifer’s face as the implication caught up with him. “I… wait. How much of that are you…?” His eyes flicked towards the graph, and whatever he saw there appeared to make the situation considerably worse. “Is that… are all of those…?”

Belphegor glanced at the data. “Some of them.”

Lucifer went very quiet.

“Right,” he managed eventually, voice several degrees higher than before. “We’re moving on.”

Together they worked further down the list. Lucifer supplied increasingly specific possibilities as they occurred to him, some sensible, others apparently intended to discover just how much Bel’s analysis could actually infer. Music had an effect, but not enough. Creating things helped occasionally. Ducks, despite Lucifer’s immediate insistence that they constituted a medically significant variable, failed to account for anything.

Winning proved more promising. Belphegor isolated several smaller events in which the pattern was recognisable: a brief surge through the reward markers, heightened arousal followed by a relatively quick drop in cortisol, the physiological satisfaction of having achieved something his brain considered worthwhile. The problem was that several of the larger positive anomalies began after readings that suggested almost the opposite. Adrenaline remained elevated, cortisol climbed rather than fell, and his cardiovascular response took considerably longer to settle, the sort of pattern Bel associated with frustration, conflict or a perceived loss of control. Yet instead of continuing into the prolonged stress response she would have expected, those episodes were followed by some of his strongest improvements.

Lucifer studied the offending sections of the graph. “So you don’t actually know that I lost.”

“I know your body thought something had gone badly.”

“That is very different.” He gestured towards the hologram with renewed authority. “My body lacks context.”

Belphegor looked at him.

Lucifer folded his arms. “I have an extremely sophisticated relationship with victory.”

Bel gave him a long look and moved on.

The process became unexpectedly absorbing. For the first time since waking, Lucifer forgot to be self-conscious about the information floating in front of him. He shifted closer to the projection, occasionally reaching through it to enlarge a date himself, and Bel allowed him to take over more of the navigation as they worked. Whatever her hypothesis was, she seemed determined not to hand it to him before he had seen the pattern she had seen.

Lucifer eventually isolated three of the largest spikes and pulled them alongside one another. “These are almost identical.”

“Very similar.”

“And you’ve checked everything around them?”

“Everything I’m authorised to check.”

Lucifer barely registered the distinction, his attention catching instead on the small file symbols beneath each highlighted timestamp, and when he enlarged one only to find an attachment waiting there, his frown deepened. He checked the neighbouring anomaly, then another, finding the same thing each time before slowly turning towards Belphegor. “What exactly am I looking at?”

For just a fraction too long, her attention remained fixed on the hologram, that increasingly familiar trace of sheepishness settling over her features before she seemed to accept that there was no particularly reassuring way to phrase the answer. “Footage associated with the timestamps.”

The hand still suspended inside the projection became very still as whatever response had initially occurred to Lucifer appeared to require several revisions before it could be spoken, his attention travelling from Belphegor to the neat row of attachments and back again as disbelief gradually displaced curiosity. “You have footage.”

“The system has footage,” Bel corrected, and when Lucifer’s expression suggested that this distinction had done absolutely nothing to improve matters, she lifted a hand before he could gather enough momentum to object. “I haven’t watched it. The monitoring system correlates significant physiological changes with environmental records available at the same timestamp, and when it identifies a sufficiently strong match, it attaches the relevant file to the reading. I can see that footage exists and when it was recorded, but my medical authorisation doesn’t permit me to access the contents.”

Some of the outrage gathering in Lucifer’s face faltered at that, only to return in a subtly different and considerably more bewildered form as he looked back at the hologram. There were far too many attachments for comfort. “I’m sorry, where the fuck is it getting environmental records of me?”

“Several sources, apparently, though identifying them would require opening the associated file information, which I’m also not authorised to do.”

He stared at her for a long moment, then dragged a hand slowly down his face as the absurdity of the situation accumulated faster than he could process it. He had begun this examination objecting to a dressing change and somehow arrived, less than a day later, at the discovery that an unknown system had spent years collecting his vital signs and attaching mystery surveillance footage to moments when his endocrine system behaved suspiciously well. When his hand finally dropped, he looked almost personally betrayed by the hologram hovering in front of him.

Belphegor waited, making no attempt to steer him towards a decision, while the files remained unopened between them and Lucifer’s eyes moved reluctantly back towards the largest spike. Curiosity was already beginning to wage a deeply unfair battle against principle. He lasted perhaps another ten seconds before irritation won out over both.

“Fine. Fine, I authorise it.” He waved towards the projection, then immediately raised a finger as Bel reached for the tablet. “For this. Specifically this. You may access the footage attached to these readings for the sole purpose of discovering why my apparently treacherous body keeps having secret good days without consulting me first. That is the extent of the permission.”

She inclined her head and began bringing up the access controls, only for Lucifer to lean forward again as another possibility occurred to him. “And you are not browsing through anything else while you’re in there. No wandering off through two centuries of whatever horrifying archive this thing has assembled, no saving anything, and absolutely no deciding that something is medically relevant because you happen to find it interesting.”

“I understand.”

Suspicion followed every movement as Bel entered the authorisation, Lucifer’s embarrassment over the earlier discussion of physiological markers apparently still fresh enough to inspire one final addition. “And if any of those files contain something I would reasonably prefer my doctor not to see, we close it immediately.”

Her fingers hovered over the tablet. “Define reasonably.”

His expression tightened at once. “You know what, I already regret this.”

Nevertheless, Lucifer settled back against the pillows and made an impatient gesture towards the waiting files, resignation and curiosity now thoroughly entangled. “You have my authorisation. Open the first one.”

Belphegor’s fingers moved towards the latest anomaly, though she stopped before touching it. For a moment she studied the collection of peaks suspended between them, her expression losing some of its earlier clinical detachment as though the shape of the data had begun to remind her of something considerably older than the months displayed there.

“I do have a hypothesis,” she said eventually. “I didn’t want to give it too much weight without confirming the timestamps, but these spikes are familiar.”

Something in her voice made Lucifer look at her rather than the hologram.

Bel enlarged one of the anomalies, laying several of its markers over one another. “I’ve seen your body respond like this before. The combination is slightly different, and you were considerably healthier then, so the baseline makes comparison difficult, but the pattern is close enough that I noticed it almost immediately.” Her hand lowered, leaving the data suspended between them. “It resembles the way you used to respond after spending time with Lilith.”

For a moment Lucifer did not move.

The name found somewhere tender despite the years he had spent teaching himself otherwise, and his attention returned slowly to the glowing lines as though they might become less recognisable if he stared at them long enough. Eight years had taken some of the immediacy out of missing her, but apparently not enough to stop the old instinct to reach for his phone, to send another photograph of Charlie or some ridiculous thing he had made, to offer small pieces of his life into a silence that never offered anything back.

“Lilith hasn’t replied to a single message I’ve sent her in eight years.”

The words came without humour, quieter than anything he had said for several minutes, and Belphegor let them remain between them without trying to soften what they meant.

Lucifer swallowed and looked away from the graph. “So unless my endocrine system has developed the ability to sustain a long-distance relationship entirely by itself, it isn’t her.”

“No,” Bel said gently. “I didn’t think it was.”

Her gaze returned to the anomalies, and when she continued there was something careful beneath the clinical precision. “I think someone else is making you feel something your body remembers.”

The words changed the shape of the investigation.

Until now the graphs had been an abstraction, an entertaining betrayal committed by his own physiology, something he could prod at and argue with while Bel methodically dismantled his theories. Now the attachments hovered amongst the data with the uncomfortable promise of an answer. Somewhere inside that file was a person, perhaps caught doing something utterly ordinary, who had reached him deeply enough for his body to recognise an old pattern even when Lucifer himself apparently had not.

His first instinct was to dismiss the entire thing. Hormones were hardly prophecy, and resemblance was not equivalence; whatever Bel had found could be coincidence, circumstance, some ridiculous combination of stress and proximity that would become obvious the moment they saw what had actually happened. He almost said as much, could already feel the argument arranging itself into something reassuringly dismissive, but the words never quite made it out.

Because he wanted to know.

That was the part he could not explain away.

Lucifer’s gaze travelled from the glowing peaks to the small file attached beneath it, and for the first time since discovering the footage he made no joke about surveillance, privacy or the deeply alarming administrative habits of Belphegor’s monitoring system. He simply stared at it, aware of his pulse in a way that felt particularly unfair given the circumstances.

Eventually Lucifer drew in a slow breath, settled more firmly against the pillows and gave the smallest nod.

“All right.”

Only then did Belphegor touch the attachment, and the graphs dissolved to make room for whatever his body had apparently understood before he did.

The hologram flickered once before resolving into the familiar colours of the Hotel lobby.

Lucifer recognised the angle immediately. The footage had been taken from somewhere high near the staircase, wide enough to capture most of the room, and for a few seconds there was nothing remarkable about it at all. Charlie crossed through the background carrying a stack of papers, Husk occupied his usual place behind the bar, and then Lucifer himself appeared at the edge of the frame, striding in through the front doors in a pink coat he vaguely remembered wearing sometime shortly after moving into the Hotel.

He had barely made it three steps inside when something red dropped neatly into frame from the upper landing.

Alastor.

Lucifer’s stomach dropped so violently that for one sickening moment he thought the pain had come from his ribs.

It had not.

Understanding arrived whole.

There was no gradual assembly of evidence, no comfortable period of uncertainty in which he could examine the possibility and decide whether he believed it. He saw Alastor and knew, with the terrible intimacy of recognising something he had been carefully refusing to name.

Every encounter with the bastard seemed to begin the same way. That voice needling at him, that smile widening whenever Lucifer’s patience began to fray, Alastor somehow finding the precise combination of words required to turn irritation into genuine fury and then standing there looking delighted with himself when it worked. From their first meeting he had been insufferable. Smug. Proprietorial. Far too comfortable around Charlie. Lucifer could still remember the almost immediate flare of hostility when Alastor had draped himself around her and started talking about everything he had supposedly done for her, each affectionate Charlie and pointed little claim upon her attention landing exactly where Alastor intended it to.

Lucifer had hated him almost instantly.

He had also been more awake during that ridiculous confrontation than he had been in months.

The thought landed with enough force to make his stomach turn.

He remembered the stupid song, Alastor answering his performance with one of his own, both of them escalating because neither seemed constitutionally capable of allowing the other the final word. He remembered Alastor leaning into his space with that fixed smile, Lucifer crowding straight back, magic prickling beneath his skin while Charlie desperately attempted to keep the entire thing from becoming an actual fight.

He remembered how good it had felt to have something to push against.

That was all.

It had to be all.

Then Bel’s comparison to Lilith returned to him, and something inside Lucifer seemed to fold.

“Nope!”

His hand moved through the projection before he appeared aware of having raised it. The footage vanished so abruptly that Alastor disappeared halfway through turning towards the version of Lucifer on the screen.

For several seconds Lucifer simply stared at the empty space where he had been.

His heart had begun beating too quickly. He could feel each pulse in the bruised cage of his ribs, could feel the room becoming too warm despite the open window, and some frightened part of him wanted the graphs gone as well, the tablet shut off, Bel out of the room before she could look at him long enough to understand what he already had.

Because he knew.

He knew before they had even watched enough footage to prove anything.

And beneath that knowledge came another thought, quieter and infinitely worse.

Lilith.

Eight years of silence. Eight years of messages disappearing unanswered into wherever she had gone. Years before that spent loving her through distance and anger and the slow disintegration of something Lucifer had once believed too fundamental to him to ever end. He had built so much of himself around that absence that he no longer knew where missing her stopped and simply being himself began.

Now Bel was telling him that his body recognised the same pattern around someone he could barely stand.

“No,” he said again, stronger this time because the first had sounded dangerously close to fear. He shifted backwards against the pillows until there was nowhere further to go, one hand finding the front of his robe and holding it closed over his ribs. “That one’s useless. He’s always here. He lives here. Of course he’s in the footage, he’s in fucking everything.”

Belphegor’s brow furrowed. “We saw four seconds.”

“Exactly. Four seconds. Completely meaningless. You cannot establish anything from four seconds.”

Bel’s attention settled on him rather than the data, and Lucifer could almost see the moment she stopped thinking like a researcher confronted with insufficient evidence and started thinking like a doctor confronted with a patient whose response had become evidence of its own.

He hated it.

“Pick another one.”

Bel hesitated.

“Please.”

The word came out before Lucifer could dress it in anything sharper.

Something shifted in Belphegor’s expression, but she spared him the indignity of acknowledging it and selected another anomaly earlier along the timeline.

The recording opened into darkness.

Then music began to play.

A jaunty piano introduction spilled from the projection, bright and theatrical and horribly familiar.

Lucifer’s blood went cold.

He knew the melody.

Of course he knew the fucking melody.

He had written half of it.

His hand shot towards the projection. “Stop.”

The music died.

Lucifer sat rigidly amongst the pillows, staring at the frozen image while memory supplied everything Bel had not yet seen. Alastor stepping into his song as though he had been personally invited. That obnoxious grin. The immediate challenge threaded through every line. Lucifer answering because there had been no conceivable universe in which he was going to stand there and let some radio-themed prick imply that he had been a better father to Charlie.

The second file should have helped. Different circumstances, another opportunity for coincidence to rescue him.

Instead, Bel had found the fucking dad-off.

Belphegor looked from the suspended footage to Lucifer, confusion deepening. “We still haven’t seen what happened.”

“I know what happened.”

The admission escaped before he could stop it.

Silence followed.

Lucifer’s face tightened.

Bel did not ask.

Perhaps that kindness was what undid him. Lucifer looked down at his hands and found them trembling faintly against the duvet, so he curled them into the fabric until they stopped being visible. “It was an argument. A musical argument, because apparently dignity abandoned this establishment some time before I arrived, but an argument nonetheless. He was deliberately provoking me.”

His voice had begun moving too quickly again.

“He does that. Constantly. It’s practically his only hobby.”

Bel reached towards the controls.

Lucifer looked up. “Don’t.”

Her hand stopped.

He wanted her to listen. He wanted her to close the entire thing and tell him they had enough information, that the resemblance had been superficial, that she had been wrong to mention Lilith and there were a hundred physiological explanations for why Alastor’s presence had somehow carved bright little peaks through months of depression.

But the file remained there.

And Lucifer knew that if they stopped now, he would spend every quiet moment wondering whether he had been right.

His fingers loosened painfully from the duvet.

“Just…” He swallowed. “Just do it.”

Bel resumed the footage.

The music burst back into the room and the image sharpened around it, catching Lucifer and Alastor already locked into the ridiculous escalation. Even without sound the hostility would have been obvious. They crowded one another’s space with matching theatricality, each interruption answered immediately by another, Alastor’s smile sharpening whenever Lucifer rose to the bait and Lucifer looking increasingly prepared to demonstrate exactly why provoking the King of Hell was generally considered a poor survival strategy.

Then Alastor leaned into view properly.

Lucifer flinched.

Watching it from outside himself was somehow worse.

He could see the fury in his own face, the jealousy, the affront at finding this man standing in a place beside Charlie that Lucifer feared he had forfeited through years of absence. There was nothing soft about the interaction. Nothing tender. Nothing that should have belonged anywhere near the pattern Bel had recognised.

Yet the Lucifer on the screen was incandescent with it.

Present.

Engaged.

Alive in a way that made the months surrounding that moment look suddenly, painfully grey.

Belphegor let the recording continue a little longer before pausing it herself and drawing the physiological data alongside the image. Lucifer had the deeply unpleasant experience of seeing the evidence arrange itself beside Alastor’s frozen grin.

“This is one of the larger spikes,” she said. “Your initial response is exactly what I would expect from what I’m seeing. Heart rate rises sharply. Adrenaline and cortisol increase. There’s a sustained sympathetic response throughout the confrontation.”

Lucifer seized on it immediately. “There. He pissed me off.”

Relief loosened something in Lucifer’s chest, and he gestured towards the graph as though Bel had finally arrived at the obvious conclusion he had been trying to hand her all along. “He’s exceptionally good at it. Possibly his only genuine talent.”

Belphegor’s attention remained on the data. “That isn’t the part I’m interested in.”

The relief stopped almost as quickly as it had come.

She moved the timeline forward, carrying them beyond the confrontation and into the hours that followed. The sharp physiological response began to recede, adrenaline dropping away and his heart rate settling, but instead of simply returning to the miserable baseline that dominated so much of the surrounding data, several of the other markers continued moving with it.

“Your stress response resolves unusually quickly afterwards,” Bel said. “Cortisol falls below the level it was at before the interaction, your heart rate variability improves, and the broader pattern becomes considerably more stable. The acute response to him is antagonistic. What happens afterwards isn’t.”

Lucifer stared at the graph for several seconds with apparently nothing to offer it before his shoulders lifted in a small, brittle shrug. “So I enjoy arguing with him.”

The explanation sounded reasonable enough that he appeared to take some comfort from it. He shifted against the pillows, carefully casual now, as though they had finally reached something ordinary enough to dismiss. “People enjoy arguing. It’s stimulating. He irritates me, I irritate him, occasionally one of us threatens the other with bodily harm. Very healthy social interaction by Hell’s standards.”

Bel did not smile, and Lucifer’s own attempt at one faded beneath her silence.

“It could account for some of the response,” she said. “It doesn’t account for the consistency of it.”

He looked back at the hologram.

Bel drew several of the other anomalies into view around the first. The peaks varied in size and duration, but once she placed them together the resemblance became difficult to ignore. Different dates, different circumstances, the same strange movement away from the long decline surrounding them.

Lucifer’s fingers tightened slowly in the duvet.

“He gets a rise out of me,” he said. The dismissiveness remained, but it had become quieter, worn thin by repetition. “That’s hardly a revelation. He’s obnoxious, territorial, smug beyond all reasonable measure and apparently incapable of seeing me enter a room without deciding his day would be improved by making me angry. Of course I react to him.”

A slight inclination of her head conceded the point without interrupting him. The agreement caught Lucifer off guard, drawing a brief, uncertain glance in her direction. After considering the clustered anomalies for another moment, Belphegor continued. “I’m not suggesting the antagonism isn’t real. Your readings make it very clear that it is. You find him intensely irritating—”

“Thank you.”

“—But irritation explains what happens while he’s provoking you.” Her gaze shifted towards Lucifer. “It doesn’t explain why you are repeatedly better afterwards.”

The room seemed very quiet around them and Lucifer looked back at the data finding himself without anywhere useful to put his attention. The graphs were bad enough. Alastor’s frozen face beside them was worse. He could dismiss an argument, dismiss adrenaline, dismiss the simple fact that the Radio Demon possessed an almost supernatural ability to make himself impossible to ignore. What he could not quite dismiss was the pattern continuing after all of those things should have ended.

His eyes caught briefly on Alastor’s smile.

Something tightened painfully beneath his ribs that had nothing to do with the fractures.

“You can’t take that and turn it into something else just because the pattern looks familiar.”

Belphegor remained quiet.

Lucifer looked away first.

“It doesn’t mean what you think it means.”

This time, he sounded like he was asking her to agree but her attention remained on the data for a long moment, moving between the sharp initial response and the slower improvement that followed it. When she finally spoke, there was none of the careful humour she had permitted elsewhere in the examination.

“I think he makes you feel alive.”

His attention snapped towards her, but Bel continued before he could gather enough offence to interrupt. “I don’t mean happy, necessarily. He irritates you. He challenges you. There are several points here where your stress response suggests you would have been perfectly content to throw him through a wall.” She drew the clustered anomalies closer together, studying them as she spoke. “But you engage with him. Fully. Your attention sharpens, your energy increases, and afterwards you recover instead of falling immediately back into the same pattern of withdrawal. Whatever else is happening between you, he is reaching a part of you that has been largely dormant for a very long time.”

That was enough to make Lucifer look away, because dormant was an offensively clinical word for it and, considerably worse, a difficult one to argue with.

There had been a spark once, though he had never thought of it in anything so sentimental. He had simply been himself. Loud, curious, impossible to contain, forever reaching towards the next idea before the previous one was finished. Heaven had done its best to punish that out of him. Hell had given it other places to go. Lilith had once met him there, matching his ambition with her own until the two of them could make an eternity feel insufficient for everything they intended to build.

Somewhere along the way, Lucifer had stopped expecting anyone to meet him there at all.

Belphegor moved one of the recordings alongside the graph. “He also doesn’t appear to frighten you.”

Lucifer gave her a deeply unimpressed look. “He’s just a sinner.”

“I’m aware.”

“I could turn him into vapour.”

“We both know you cannot.”

The objection lost momentum before it could become an argument, and Bel returned to the data. “That matters. You can spar with him without your body responding as though the conflict itself places you in danger. He pushes you, you push back, and neither appears to require the other to yield before the interaction can continue. Given the rest of your readings, that seems significant.”

One hand moved unconsciously over the robe covering his ribs, and Bel gave the gesture enough time to pass before turning her attention back to the collection of timestamps. “There’s something else.”

She opened one of the attached files, muted the audio and doubled the playback speed. Lucifer watched himself cross the hotel lobby only for Alastor to appear at his side moments later; Bel skipped forward, opened another, and there he was again, approaching Lucifer at the bar. A third showed Lucifer leaving whatever exchange they had been having, followed by a quick blur of uneventful footage before Alastor sought him out elsewhere in the hotel. Bel flicked through several more in rapid succession, each reduced to the same strange little sequence of approach, interaction, departure and eventual reappearance.

“These interactions aren’t always initiated by you,” she said, pausing on yet another frame containing the two of them. “In several of the recordings, he seeks you out, starts whatever exchange follows, and then, when you disengage or remove yourself, approaches you again later. Whatever his reasons for doing it, that part of the pattern is remarkably consistent.”

Something unpleasantly vulnerable opened beneath Lucifer’s sternum, and he stared at the data for several seconds before a short laugh escaped him, incredulous enough to carry the beginnings of his old self with it. “Yes, Bel, because he likes annoying me. I cannot emphasise this enough. The man derives an absolutely obscene amount of pleasure from being a pain in my arse.” Another laugh followed, softer this time, as Lucifer gestured towards Alastor’s frozen image with the air of someone presenting evidence so conclusive that continuing the investigation ought to constitute professional misconduct. “He seeks me out because irritating me is apparently enriching to him. It’s recreation. Possibly sustenance. I wouldn’t be surprised if half his power comes from finding me in a perfectly acceptable mood and deciding to ruin it.”

Belphegor made no attempt to dispute that assessment, accepting Alastor’s apparent dedication to irritating him as fact while her attention remained on the pattern spread across the hologram.

Lucifer caught the gesture and latched onto it immediately. “Exactly. Thank you. Finally, some medical sense.” The spark of satisfaction lasted only until he noticed that Bel had not dismissed the data and was instead drawing several of the encounters closer together. His smile faltered around the edges. “What?”

“His enjoyment of provoking you doesn’t change what I’m seeing. He keeps choosing to engage with you.”

The word slipped neatly beneath every defence Lucifer had been assembling.

Choosing.

He wished she had used almost any other one.

For years, people had learned to leave him alone, and Lucifer could hardly blame them when he had devoted so much time to teaching them how. Calls ignored often enough eventually stopped coming; invitations declined became invitations never sent; doors remained closed until even people who loved him learned that knocking only produced silence from the other side. He had spent years making himself difficult to reach because being reached meant answering questions he did not know how to answer, and eventually the world had done the reasonable thing and respected the distance he had demanded.

Alastor, apparently, had never developed the good sense to do the same.

The thought brought with it an image so immediate and so profoundly stupid that another breath of laughter escaped Lucifer before he could stop it.

The fucking sign.

The enormous NO ALASTOR ALLOWED sign currently affixed to his bedroom door. Belphegor had almost certainly walked directly past it on her way into the room, including the crude approximation of antlers Lucifer had added only recently, complete with an emphatic line struck through the middle when the original wording had proved insufficiently persuasive. He had quite literally constructed, decorated and subsequently amended a physical declaration that one particular demon was unwelcome in his personal space, and Alastor had treated it with roughly the same respect he afforded most of Lucifer’s attempts to establish authority over him.

Which was to say none whatsoever.

The bastard had read it. Lucifer knew he had read it, because Alastor had spent an offensively long time examining the thing before criticising the quality of the likeness. After that, the sign seemed to become little more than another private joke at Lucifer’s expense. A closed door did not discourage him. Being told to fuck off merely postponed him. Lucifer could dismiss him with all the royal indignation he possessed and somehow still find that yellow grin appearing again later, armed with a fresh provocation and apparently no memory whatsoever of having been explicitly informed that his company was unwanted.

Lucifer had complained about it incessantly.

What he had never done was genuinely expect Alastor to stop.

The realisation stripped the remaining amusement from his face.

Somewhere along the way, beneath all the snarling and slammed doors and elaborate declarations that Hell would be vastly improved if the Radio Demon discovered somewhere else to exist, Lucifer had acquired the quiet certainty that Alastor would come back. He could be difficult with him. Petty, hostile, withdrawn, thoroughly unpleasant. He could shut the door and make it abundantly clear that he had nothing to give anyone that day.

Alastor came back anyway.

Belphegor watched him for a moment before returning to the data. “I think that matters more than you realise. He gives you someone to push against without making you feel powerless. He challenges you, and you respond. He irritates you enough to make you participate when your broader pattern suggests that, left to yourself, you would often withdraw instead. There’s energy in that response that has been absent from most of your readings for a very long time.”

Lucifer’s gaze remained fixed somewhere beyond the hologram.

“You’ve spent years making it easy for people to leave you alone,” Bel continued, quieter now. “He doesn’t seem particularly interested in taking you up on the offer.”

Lucifer’s throat tightened.

The stupid sign was still on the other side of the door.

For once, being difficult had failed to make someone leave.

He recoiled from the thought almost as soon as it formed, irritation rushing in to smother whatever else had threatened to surface. “No. Absolutely not.” He pushed himself a little straighter against the pillows, wincing when his ribs objected but carrying on before Bel could interfere. “We are getting dangerously sentimental about a man I hate, Bel. Hate. Loathe. Despise. If Alastor vanished tomorrow, I would personally organise the celebration, provide refreshments and commission a commemorative plaque thanking whatever benevolent force finally removed that insufferable, grinning, radio-shaped haemorrhoid from my life.”

The force of it brought some colour back into him, and once Lucifer had begun he seemed almost relieved to find himself on familiar ground. “He is smug, invasive, irritating beyond the limits of language, dresses like someone upholstered a murder scene, has absolutely no concept of appropriate boundaries and has spent a frankly astonishing amount of time since I arrived here attempting to provoke me for his own entertainment. I do not find his persistence charming. I find it infuriating. The fact that he keeps coming back after being explicitly told to go away is not some profound statement about devotion, it is evidence of a serious personality defect.”

The torrent was allowed to run its course until Lucifer finished slightly breathless, one hand still raised as though he had been addressing a particularly difficult jury. There was something almost triumphant in his expression now, as though sheer comprehensiveness had settled the matter beyond reasonable appeal.

A brief glance towards the data rather undermined his victory. “Biochemically, that isn’t what I’m seeing.”

The triumph disappeared as Lucifer stared at her. “Excuse me?”

“I’m not disputing that you dislike him. You clearly do.” Bel drew the cluster of anomalies closer, letting the pattern sit between them rather than immediately explaining it away. “But sustained aversion doesn’t usually produce this. If his presence were simply an unwanted stressor, I would expect repeated exposure to maintain or worsen the response, particularly given your existing baseline.”

Lucifer’s mouth tightened. “Perhaps I hate him in an unusually healthy way.”

A faint trace of amusement touched Bel’s expression. “Apparently.”

“Good. Excellent. Put that in the notes.”

The tablet remained untouched, and Lucifer’s fragile satisfaction lasted perhaps a second before he realised Bel was still looking at the graph.

“Bel, please just drop it.”

“You can hate him,” she said, and there was enough certainty in it that Lucifer stopped preparing his next defence. “I’m not trying to tell you what you consciously feel. I’m telling you that hate, on its own, doesn’t account for what your body is doing around him.”

His gaze slipped unwillingly towards the frozen footage.

Alastor remained there in profile, wearing the same smile Lucifer had spent months wanting to slap from his face.

“This isn’t romantic,” Lucifer said.

Belphegor’s attention shifted to him. “I didn’t say it was.”

That stopped him more effectively than disagreement would have. Heat crept slowly into Lucifer’s face as he realised that, in his haste to defend himself against an accusation Bel had never actually made, he had supplied it for her.

She had the grace to leave that untouched.

Lucifer looked away, jaw working once before he found somewhere safer to put the conversation. “Then what exactly are you saying?”

Bel studied the readings before answering, taking enough time that Lucifer’s impatience had nowhere to go except into the restless movement of his fingers against the duvet. “I think this sinner is bringing something back. Engagement. Curiosity. Competition. Irritation, certainly. Anticipation.” She moved through the data as she spoke, tracing the repeated departures from the long, flattened decline surrounding them. “Your readings have been telling me for years that less and less reaches you. Then he appears, and suddenly something does. You react to him. You keep reacting after the interaction is over. Whatever name you eventually decide to give that, if you give it one at all, I don’t think the important part is whether you like him.” Her eyes lifted from the hologram to Lucifer. “I think the important part is that he interrupts the grief. Not permanently, and I don’t think he makes you forget it, but when he’s there it stops occupying all of you. You engage with something outside it, and you’re beginning to do that more often.” Belphegor let her attention rest on him, the clinical distance in her expression softened by something older and considerably more personal. “After this long, Lucifer, I think that matters.”

There was very little he could say without opening doors he had spent years keeping firmly shut, and he had already endured quite enough emotional excavation for one medical examination. His attention settled instead on Alastor’s frozen image, unaware that somewhere in the future his existence was being discussed as a possible intervention for several millennia of unresolved grief.

The absurdity of the situation began to creep in around the edges of everything else, enough that Lucifer might even have found it funny if he had not noticed Belphegor returning to her tablet. He knew that particular posture far too well by now, the slight lowering of her head as her attention settled into whatever she was recording, fingers moving with the calm purpose of someone who had reached a conclusion and was already committing it to his medical history. Suspicion immediately displaced what remained of his melancholy, and Lucifer narrowed his eyes at her from across the hologram. “Bel, what are you doing?”

“Updating your treatment plan.”

For several seconds he simply watched her continue typing, waiting for the rest of that sentence to become less concerning on its own. It did not. “Why,” he asked eventually, leaning forwards just enough to try to glimpse the tablet, “do I have the horrible feeling that my treatment plan suddenly involves Alastor?”

“Because based on what we’ve established, regular interaction with him appears beneficial.”

A laugh escaped Lucifer before she had quite finished, incredulous and unexpectedly genuine, and he immediately pressed a hand against his ribs when they objected to it. “No. Absolutely not. We have established that he is an irritating bastard with a statistically significant talent for interfering with my depression, which is a sentence I already resent having to say aloud. We have not established that he constitutes medical care.”

Belphegor continued entering her notes with infuriating tranquillity. “It’s sufficient for a recommendation.”

Lucifer’s amusement faltered as he looked from her to the tablet and then, with growing suspicion, towards Alastor’s frozen image still suspended beside the data. “Bel, what exactly are you recommending?”

Rather than answer immediately, Bel finished the entry, reviewed it once and turned the tablet towards him.

Lucifer read it, his expression slowly collapsing as the full indignity of what Bel had written sank in.

“You cannot prescribe me Alastor.”
