Chapter Text
Shadow was trying to ignore it. He was fine.
Shadow was fine.
He couldn't let the fire beneath his skin break free, no matter how fiercely it consumed him. He would endure it. Learn to live with the pain until it became nothing more than another part of himself. Then everything could go back to normal.
Or as close to normal as a bio-engineered hedgehog had ever been.
He knew he needed to get himself under control. Slow his breathing, force the frantic rhythm in his chest to settle. Ease the tension locked through his muscles, smooth his quills, and just lay in bed like a normal person.
But he couldn’t.
Shadow had curled himself into the tightest ball he could manage, pressed into the farthest corner of his room as if the walls themselves could shield him from whatever was happening inside his body. The room was dark, only the faintest sliver of city light crept through the blinds.
His quills were raised high and flaring out in every direction, twitching with sharp, uncontrollable bursts of movement. Some buried instinct whispered that this posture meant protection and safety. That if he made himself small, bristled out his quills, kept his stomach covered, then nothing could strike him where he was vulnerable.
It was neither rational nor fully conscious. Something feral seized him and moved his body while his mind strained uselessly against the current.
He despised that helplessness. He despised every brutal inch of it.
But as another pulse of pain rolled through his body, he couldn’t stop himself from curling tighter, quills rattling as if trying to ward off a threat he couldn’t see.
It left him wondering what the hell he was even protecting himself from. Himself? His inability to just be normal? To function like he should? He was utterly pathetic.
The pain was getting worse, it wanted out. He couldn’t let it. He wouldn’t let it.
He clenched his eyes shut as the pain clawed its way through him, burning deep beneath his skin like something alive. Something caught in his throat then, and when he tried to force air back into his lungs it escaped as a low growl followed by several dry clicks.
He felt sick. He knew those sounds. He’d heard them before, a few years ago, echoing from the Black Arms soldiers as they tore through everything in their path.
And now those noises were coming from him.
He tried to clear his throat, but the next breath produced another.
Out. Out. Out. OUT.
If he were truly honest, he could not call it a surprise. Whatever this was, it had been with him for a very long time, locked out of sight until now. His body was not changing into something else so much as finally giving up the lie.
And after all the time he’d wasted trying to show he was something more than the monster they saw him as.
For a time, that was all he amounted to in their eyes: a mistake, a hybrid error that had dragged an alien invasion to Earth, the so-called monster who had once threatened their hero. Every insult under the sun, he’d heard it. It didn’t bother him as much as it should have. Or at least, that’s what he told himself.
Though, soon enough, people began to come around. The hatred for him slowly dulled, the fearful glances turned into cautious curiosity, and the whispers of monster quieted to silence. Some even started to see him as something more than a weapon… maybe even as a person. He could mostly thank the blue idiot for that. Sonic had stood up for him when no one else would, always going on about how it was “not fair” for people to judge him without knowing him, with all that infuriatingly noble nonsense about giving him a chance to be seen for what he actually was. Shadow had let him do it, let him speak on his behalf and chip away at the story the media had built around him.
Now, Shadow was beginning to realize that maybe all this time, he hadn’t been trying to prove it to them at all. Maybe he’d only been trying to convince himself. That he was in control, that he was more than the weapon they made him to be. But that illusion was breaking. Piece by piece, everything he’d built to hold himself together was being stripped away. And what terrified him most was the thought that maybe the monster they saw back then had been real all along.
Chaos, he was glad Rouge was gone. She’d mentioned a G.U.N. mission before leaving… at least, he thought she had. Hard to be sure when the ringing in his ears drowned out most of her voice.
Rouge had been hovering ever since the day he’d asked for an extended leave from G.U.N. missions. Actually, hovering wasn’t even the right word, she’d been outright frantic, though she tried to hide it under her usual snark.
Commander Tower hadn’t exactly taken the request well either; the man’s frown could’ve split concrete. But Shadow couldn’t bring himself to care about Tower’s disappointment, or anyone else’s for that matter. He’d been too exhausted to pretend, too drained to hide the strain in his voice, and Tower seemed to recognize it for once in his life.
Maybe it was the tired look in Shadow’s eyes, but the commander didn’t really press the issue. He didn’t interrogate him. He didn’t even demand a reason.
Just gave a stiff nod and let him go.
Shadow wasn’t sure if that made everything better or worse. Either way, he took what he could get.
Rouge’s fretting about doubled when he began to isolate himself inside his apartment. He knew Rouge wouldn’t allow him to just disappear off the face of the planet like he wished he could, but her worrying felt excessive.
Eventually he allowed her to come inside to check up on him every now and then, just to get her off his back. She would even insist on bringing food every few days regardless of the fact that he repeatedly told her not to. She would then bombard him with questions that he didn’t have answers to (or more so didn’t know how to answer). And afterward, he would thank her, promise he’d eat later, and hope she couldn’t see through the lie. Once she was gone, the food went straight to the trash. It had become a routine; a sad, silent ritual that had lasted nearly two months.
He did feel mild guilt for wasting the food, but he supposed it wouldn’t have stayed in his stomach anyways. He hadn’t been able to keep anything down in over a month at that point.
And it’s not that Shadow didn’t appreciate Rouge’s concern, he did. Rouge was the first person Shadow allowed himself to get close to after the ARK. He just couldn’t allow himself to be around her. He couldn’t let Rouge see what he had become.
He knew it was selfish to keep it from her. She had every right to know, but the thought of her seeing what he’d become mortified him. He was already sickened by his own reflection, he couldn’t bear to see that same revulsion in her eyes. If he couldn’t even look at himself without disgust, how could he expect her to?
He just needed to be alone, he needed to learn how to control it. To suppress it. To just live with the pain. To just be normal.
Shadow had always taken pride in his discipline, in the control that defined him. The way he could dictate every aspect of his very existence. His body was crafted for precision and power— a weapon, a tool. The Ultimate Lifeform.
But now, he felt hollow, undone, something less than what he was meant to be. His body threatened to tear itself apart and become something completely new right before his eyes. His blood continued to boil as he felt the way those ginormous, retched wings were just waiting to painfully burst from his shoulder blades, he felt his claws pushing against the thick fabric of his gloves, desperate to break free. His fangs had lengthened, becoming unnaturally sharp, no longer sitting right in his mouth, as if they no longer belonged there at all. He could feel his tail ever so slightly constricting and tightening, desperately trying to reshape itself into something foreign. He was almost fascinated with the way everything about him simultaneously felt so wrong and alien yet somehow so familiar and natural.
He tried to convince himself over and over again that it was nothing. That he could just live with it all under his skin forever; that if he did, everything would be fine again. He had been through worse. So much worse. He told himself that nothing could compare to the experiments he was put through on the ARK, and he knew nothing could ever compare to the pain of the disaster that followed. If he just stopped being so damn pitiful.
It hadn’t even been three months since it first started. The slow, creeping feeling that his strength was slipping away. He had felt sluggish, and every movement he took was sloppy and leaden. It was completely uncharacteristic of him, Shadow doesn't experience fatigue like a regular, mortal person. But of course, Shadow kept insisting to himself that nothing was wrong. It was a lie he clung to, all because it just felt like the easier option. So, he continued to just ignore it. Telling himself that he was just using too much chaos energy without enough rest. Deciding to believe his own damn lies, he hoped to ease his sudden exhaustion and weariness by limiting his use of his chaos abilities for a while, only to see if it would help. It, of course, didn’t.
Soon enough, his fatigue became impossible to ignore, even walking itself became an effort, his limbs ached and began to weigh him down, every step began to demand much more than he could give.
Before long, Shadow’s constant fatigue and aching limbs turned into something far worse. He began to feel sick. A cold, heavy type of sickness that settled deep in his bones and refused to leave. That certainly wasn’t normal. In fact, it should’ve been impossible. His body wasn’t supposed to fail him; it was quite literally designed to endure anything.
Shadow had no real understanding of what was happening to him. His own body was shifting in ways he couldn’t predict and couldn’t stop. Every day that had passed brought some new sensation, some sort of new wrongness that was spreading under his skin, and he had no answers. No logic. No control.
And worst of all, he had no one he could speak to about it.
It wasn’t a regular injury he could report. It wasn’t a mission detail he could relay. It wasn’t something he could simply hand over to Rouge and expect her to shoulder with that effortless confidence she always seemed to have.
The weight of what was happening felt crushing, it was heavy enough to suffocate him, to steal sleep from his nights and stability from his days, yet somehow still not heavy enough to justify pulling her into the mess with him.
He couldn’t bring himself to tell her. He didn’t want to see her worry deepen, and he definitely didn’t want to watch her sharp, steady gaze turn soft with concern he didn’t deserve.
So he stayed silent.
Eventually, he had even tried to eat, hoping it might bring back some of his lost energy and strength (as well as fight whatever weakness was creeping inside of him) but his body rejected it every damn time.
That was around the time he started completely pulling away from the outside world, he stopped leaving his apartment altogether. And that’s when Rouge began growing really concerned.
He would let her in his apartment a few times a week, because believe it or not, he did want the company— just to let himself feel a semblance of normalcy, just for an hour. He would try to speak as if things were normal, he would lie and make up excuses for the reasons he stopped leaving his small living space, but he knew she could sense something was wrong.
Rouge understood him better than anyone. She could read him in a heartbeat, even when he thought he was hiding it well. It annoyed him to no end. So when the involuntary twitches and spasms started, she undoubtedly caught them immediately. He was lucky enough that she knew better than to ask him about it.
He wanted to tell her. Oh, more than anything, he wanted to tell her. He wanted the weight to fall from his shoulders, to admit to her about the pain— how much it fucking hurt. He wanted to thrash and scream and sob about it. But the words refused to come no matter how much he tried to force them out.
Out of options, one day he finally gave in and let it happen. He wasn’t proud of it, but every fight proved futile, so he stopped resisting. It wasn’t surrender so much as it was silence. The kind that only comes when the struggle leaves you empty. He could only hope that if he let it pass, his body would remember how to be whole again.
He was wrong. So, so wrong.
His attempt to let it run its course backfired horribly. He hadn’t known what to expect, but the last thing he ever imagined was a violent flare of energy ripping through his skin, searing hot and blinding, and the agony, white-hot and unbearable, as something tore its way out of his back.
He fell to his knees, choking on a scream as the sound of tearing flesh filled the air. Dark, viscous blood had spilled down his sides, pooling beneath him, slick and shimmering.
And then, through the haze of pain, came the feeling of weight; massive, alien, and wrong. Huge wings unfurled behind him, their edges glinting red in the dim light, dripping with that same blood that stained his gloves.
That was all the confirmation he needed. It was always them, the Black Arms. The very part of him he'd devoted years to keeping under lock and key. The part he wished he could carve out of himself entirely.
That alien blood, their blood, was a stain he could never wash off. It pulsed through his veins whether he acknowledged it or not. Whenever he caught a glimpse of something wild in himself, something disgusting and hungry, he knew exactly where it came from.
He despised it.
He despised the idea that anything inside of him came from Black Doom. He hated that no matter how hard he fought to be his own person, he could never escape the simple, unforgiving truth:
Half of him was something monstrous.
He’d tried for years to smother it, to starve it, to ignore it, to crush it beneath discipline and control. To pretend he was only the Professors creation, only Maria’s promise, only the lifeform he’d chosen to be.
But that alien side of him never stopped whispering beneath the surface. It never stopped clawing for space, and never stopped reminding him that he wasn’t fully… anything.
Not fully hedgehog. Not fully Black Arms. Not fully weapon. Not fully a person.
Just something trapped in between, borrowing pieces from worlds that didn’t want him.
He hadn’t wanted to think about it.
That his blood was waking up again. It was twisting, changing him from the inside. It was like being pulled back into a nightmare he thought he’d already fought his way out of.
He felt sick from it. Sick with the knowledge that part of him was evolving exactly the way the Black Arms intended. With the reality that no matter how much he pushed it down… it was still there, festering, growing, and demanding to be acknowledged.
He hated it. He hated himself for having it.
And most of all, he hated the fear curling in his chest— the terrible, suffocating thought that maybe this time… maybe he wouldn’t be able to stop it.
A broken, strangled cry had torn from his throat before everything went dark. The world collapsed into silence as he’d finally lost consciousness.
When he awoke again, he had been extremely disoriented. His memory of what had just happened was splotchy, but he could remember one major thing: pain.
The next thing he knew, he was in front of a large mirror desperately trying to recognize himself. Large, heavy, tendril-like wings had indeed burst from his shoulder blades, connected directly to the tense muscles between his dorsal quills. His tail had lengthened too. Long enough to brush against the floor and curl loosely around his legs as if the thing had a mind of its own. At its tip, it narrowed into a sharp-looking shape formed entirely of dense crimson fur, creating only an illusion of danger. His gloves had torn at the fingertips, deadly claws jutting through, and his fangs were pressing uncomfortably against his mouth, too long to hide. It was then that it finally sunk in, he looked like a Black Arms.
And somehow, he still felt this was the very beginning of something far worse to come. Shadow stood before the mirror, trembling and gasping for breathe as he searched his entire body. Counting, checking, and obsessing over every change. His eyes traced the lines of his reflection, searching for anything familiar. He was desperate for proof that it wasn’t real. But the changes stared back at him, undeniable.
After a long, panicked blur of disbelief, Shadow used what little energy he had left to force the changes back. He focused every ounce of strength on suppressing the alien DNA within him, willing his body to obey. The process was agonizing— bones grinding, wings folding inward, his body twisting until it felt like it would tear apart. But somehow, it worked. When it was over, he was left shaking and broken, but he looked like a hedgehog again. From that moment on, he’s been repressing it, refusing to ever let it happen again.
Gaia, even if it killed him.
…
Knock. Knock. Knock.
And of course, someone was pounding on his front door like their life depended on it.
The sudden force of the knocking caused him to flinch and curl up further in his ball. Even the slightest movement caused pain and nausea to rack through his body. He really wished he was asleep right now, maybe then he could ignore whoever was at the door.
His tired and fogged up brain tried to place who it could even be, but no one really came to mind. Most people he knew didn’t even know where he lived (not that they would even care to visit anyways) and it couldn’t have been Rouge? …Right? Unless she’d forgotten something before she left…? But then again, that seemed highly unlikely for her.
He really hoped it was just some sort of salesman or canvasser that would leave after realizing no one would come to answer. But of course, with his luck, the knocking persisted, increasingly getting more and more aggressive by the second.
And unfortunately for Shadow, his query was soon enough answered as he heard a familiar muffled shout through the door. “Hey faker, it’s your fav guy in the whole wide world, Sonic! Just coming to check up on you!”
Shadow immediately bristled from hearing the blue hedgehogs voice. Nonononono. Sonic was the last person he wanted here. Sonic couldn’t see him like this. He looked like a pathetic mess right now. No, he was a pathetic mess right now! And he really wasn’t sure how much longer he could keep up with the agonizing pain before he straight up passed out or…
No. He abandoned that thought, he wouldn’t let it happen.
Shadow winced as he rolled out of his safe, tight little ball. He scooted backwards to lay his head against the wall as he attempted to sit upright, trying to be as quiet as possible. Everything hurt. He was aching and burning everywhere with no end in sight. But he refused to let the banging at the door distract him. He wouldn’t pay attention to it. He would quietly sit here, then Sonic would assume he isn’t home and would finally leave.
“Shadow, dude, I know you’re in there! I’m not going to stop until you come get the door!”
Shit. Shadow exhaled the breath he was holding. He knew Sonic wasn’t lying. He’s been around the hero enough to know that Sonic would be here all day if it came down to it. (That is if Sonic didn’t straight up break the door down before then).
Feeling as though he had no choice in the matter, Shadow finally shouted, “Faker, go away and leave me alone!” The words were meant to be sharp, but instead they broke apart halfway through, the sound small and ragged. He hated how weak it must have sounded. Still, the knocking ceased, and silence returned.
A few seconds passed before Sonic yelled through the doorway once again. “Please, Shadow, I came to check up on you for Rouge! She said she’s been worried? Just let me in for a sec! I’ll just make sure you’re not dying or anything, and then I’ll be out of your quills. I promise!”
Yeah, Shadow figured he wouldn’t leave that easily. No matter what he did, Sonic never seemed to get the message. He’d pushed, snapped, shut himself away, yet the blue idiot always came back. Every. Single. Time.
What baffled him even more was that Sonic never pushed him away either. Not once. For reasons Shadow still couldn’t understand, the hedgehog refused to give up on him. It made no sense. Why try so hard for someone who clearly couldn’t be saved? Why keep showing up when it was obvious Shadow wasn’t like his other friends? There was nothing left to fix. There never had been.
All he wanted right now was for Sonic to go away. Actually, he wanted everything to go away.
He wanted the noise to stop, the light to dim, the world to forget his name. He wanted to fold in on himself until there was nothing left.
No more Shadow, no more pain twisting through his veins. No more alien blood that burned and refused to rest. No more hurting the few people foolish enough to care about him.
He just wanted stillness, warmth, and silence that never asks anything of him. Just to fade and be free of it all.
The silence dragged on until even Sonic seemed to run out of words. Shadow could picture him on the other side of the door, arms crossed, shifting his weight, trying to decide what to do next. Shadow just stared at his wall, muscles tense, willing Sonic to give up and walk away.
Then came a sigh, soft but resolute. “Okay. Guess you’re not giving me a choice. I’m coming in.”
“No! Sonic, wait!” Shadow knew how pitiful he sounded, but it was his one last desperate attempt to save himself from the utter humiliation about to come his way. It still proved to be futile though, as he could already hear Sonic unlocking the front door all the way from his room. He probably should’ve predicted that Rouge would give Sonic the extra key. Damn traitorous bat.
Shadow scrambled to try to make himself look mildly presentable by attempting to comb back some of his disheveled quills, but there wasn’t much he could do while sitting on the floor. Especially since every little movement made his entire body flare up in pain, screaming at him to just let it out.
Why did he even care about what Sonic thought of his appearance? He had far worse things to worry about, not his stupid rival possibly judging his atrocious appearance.
He just didn’t want Sonic to see him like this. He’d already lost most of his dignity over the past month, piece by piece, along with the control he once prided himself on. Every day, his body twisted and reshaped itself, the chaos in his DNA clawing its way to the surface, forcing him to feel every sickening change. It had stripped away everything he’d worked for; his routine, his composure, the faint illusion of a normal, almost-happy life. And now this, Sonic seeing him like this, on the floor, struggling to move or breathe, trembling as he fought to suppress whatever his body was trying to become— it would destroy what little he had left. Shadow could already feel it slipping away.
He wanted to run, to hide, to vanish before Sonic opened that door. But escape wasn’t an option. Every movement sent fire through his veins, every breath felt like shards of glass in his lungs. His vision flickered at the edges, darkening. If he pushed himself any further, he would pass out for days on end, and he just knew he wouldn’t wake up to anything good.
Shadow shut his eyes as he heard the front door click shut. A few muffled footsteps followed: quick, confident, unmistakably his. “Alright, Shads, I’m coming in,” Sonic called out, his voice casual but edged with hesitation. There was a small, awkward laugh. “Uh, sorry for just… barging in like this. Rouge just said you’ve been ‘off’ lately? I told her you were probably fine, y’know, doing your regular broody hermit thing– but, uh, just in case…”
Shadow’s eyes cracked open, squinting toward the door as it creaked open. Sonic stepped inside, scanning the darkened room until his gaze landed on the shaken, dark figure.
“Whoa, whoa, hold up,” Sonic blurted, his cocky grin faltering into something uncertain. “Dude, what happened to you? You look like shi–”
Shadow leveled him with a flat stare.
“…Er, I mean, not great, man.” Sonic scratched the back of his quills with an awkward laugh, but the concern in his voice was impossible to hide.
Shadow usually would’ve shot something back at the blue idiot, but he really couldn’t say he disagreed with the hedgehog. He did look like utter shit. And felt like it too.
His reflection was hardly presentable. His quills had fallen into complete disarray, refusing to lie flat no matter how many times he dragged his fingers through them. His fur had become matted and dull, and dark circles had settled beneath his eyes, making the exhaustion etched across his face impossible to conceal. Slumped against the corner of his bedroom wall, he couldn't have looked more worn if he tried.
But even so, he refused to let Sonic see him as completely pathetic. He could at least try to hold on to what little dignity he had left. They’d trade a few of their usual barbs, he’d convince the hedgehog that he was fine, and Sonic would finally take the hint and leave.
Shadow let out a low, irritated sigh before snapping, “It’s none of your concern, hedgehog. I’m fine. You’ve seen me, I’m alive. Now leave.”
Sonic just stared at him for a moment, the silence stretching out between them. The hum of the air conditioning was the only sound in the room, soft and mechanical.
Finally, Sonic blinked and tilted his head. “Uh, not to, y’know, question your definition of ‘fine,’ or judge your silly quirks…” he said, voice laced with sarcasm, “but you’re literally sitting on the floor, in the dark, by yourself, and you also look kinda really terrible. Doesn’t exactly scream ‘perfectly fine’ to me.”
Shadow’s ear twitched as he shot him a glare, but Sonic’s smirk softened just enough to show the concern beneath it.
“Sonic. As I just said, I am fine,” Shadow tried to use the usual edge to his voice, but the words came out soft and shaky. To try to prove his point, Shadow forced himself to push his palms against the floor and stand upright. The motion was slow and trembly. But he did it. He managed to steady himself on both feet.
Until all of his strength left him.
His vision swam, and a low groan escaped before he could stop it. His hand shot up to his head, as if it would stop the pain from escaping. The world tilted sideways as he stumbled backwards, he caught himself on the wall before he managed to fall.
“Woah! Hey, easy!” Sonic darted forward, grabbing his arm before he fell over. The sudden contact made Shadow flinch, but he was too tired to pull away.
”Don’t–“ Shadow rasped, eyes squeezing shut. “Don’t touch me.”
Sonic refused to let go. “Yeah, uh there’s no way that’s happening,” he said quickly, his usual confidence giving way to alarm. “Shads, you’re burning up. I thought you couldn’t get sick? What’s happening to you?”
Before Shadow could answer, a sharp crack split through the silence— a surge of energy flaring up. His entire body began to pulsate violently with a crimson glow. His body arched, a hoarse, strangled noise breaking from his throat as the chaos energy burst outward in a brief, blinding flash.
Sonic stumbled back, shielding his eyes from the light. “Shadow!”
When the glow faded, Shadow was slumped against the wall again, breathing hard, shaking, the faint red glow still flickering along his veins.
Sonic blinked through the fading light, breathing hard as the air around them settled. The faint hum of chaos energy still lingered, crackling in the silence like static.
“Okay…” Sonic said slowly, “That definitely wasn’t normal.”
Shadow didn’t answer. He couldn’t. He was hunched forward, arms locked around his ribs. His claws bit through the fabric of his gloves and into his skin, hard enough to make blood well beneath his fingers. He was breathing hard and uneven from the energy ripping its way out of him. His eyes stayed shut, like if he just didn’t look up, Sonic might disappear.
”Shadow, you need to talk to me.” His tone was soft, but the edge of worry was undeniably there. “What the hell just happened? You were glowing? And that didn’t seem like your usual ‘Chaos Blast’ thingy.”
Still nothing. He was frozen.
Sonic frowned and stepped closer, crouching down to meet Shadow at eye level. “Shads, talk to me. Please. You’re scaring me a little bit over here.”
Shadow finally opened his eyes to look at Sonic, though they were hazy and unfocused. “It’s none of your concern. I am fine,” he muttered, voice low and strained.
“Bullshit.” Sonic responded, his tone sharp and raw. “You do know you’re a horrible liar, right? I’ve literally seen you take hits that could level a whole freaking city, and you still walked it off. Now you’re trembling, glowing for some reason, and can’t even stand upright?! And you’re somehow expecting me to ignore that and just leave you alone?!”
Shadow went silent again, not sure how to respond to that. His hand, still pressed tightly against his ribs, finally faltered and dropped to his side. He glanced down and grimaced. Scratches marked the dark fur along his torso, thin streaks of his blood tracing down his side. Normally, they would’ve already begun closing, his body was built to repair itself faster than anyone or anything. But lately, his energy had been so drained that even his healing factor was failing him. The sight made something cold twist in his gut.
Sonic continued to watch Shadow, he studied him for a long moment before he finally broke the silence again. “You can hate me all you want, but I am not leaving you like this.”
Shadow looked away sharply, jaw tightening until his teeth ached. He wanted to snap at him. To tell him to shut up, to go home, to stop looking at him like that. Like he was someone worth saving.
But the anger didn’t come out this time. It just sat heavy in his throat, tangled with something that felt far too much like shame.
Why did Sonic always insist on doing this? Why couldn’t he just give up on him like everyone else?
For a second, Shadow felt ready to argue again, but the words caught in his throat. His head dropped, breath trembling as another surge of pain rippled through him, forcing him to brace against the wall.
Sonic reached out again, slower this time, like one wrong move might cause Shadow to shatter completely. His hand found its place on Shadow’s shoulder, his fingers steady and light, not at all gripping. A silent anchor.
For a long moment, Shadow remained motionless. His breathing came in shallow, uneven pulls, each one faltering beneath the weight of a restrained cough. Tremors coursed through him, his body quivering from the relentless pain.
The contact unsettled him. He wasn't accustomed to being touched without purpose. Not to receive an order, not to be a subject of an experiment, not for punishment. There was no expectation behind Sonic’s touch, and Shadow didn’t know how he felt about that.
Sonic kept his voice soft, almost a whisper, “Easy, okay? Just breathe, dude.”
Shadow drew a shallow, unsteady breath. It scarcely eased the ache tightening his chest, but it was enough to keep him grounded. Tremors continued to work through him in relentless waves, every muscle quivering with pain and fatigue. Even so, the steady weight of Sonic's hand remained a quiet anchor, keeping him from giving in to it entirely.
It was humiliating. Absolutely infuriating.
But also, in some strange, distant way… relieving.
He hated himself for that as well.
The seconds stretched on in heavy silence. At last, the worst of the spasms began to subside. The pounding in his ears receded to a dull throb, and his breathing, though still uneven, gradually steadied.
Sonic made no move to withdraw his hand. He said nothing else, simply remaining where he was, watching with a level of attentiveness Shadow had rarely seen from him. The usual teasing glint was gone from those emerald eyes, replaced by a quiet, unmistakable concern.
And for the moment, Shadow didn’t have the strength to tell him to go away.
After the wave of pain finally passed, Shadow spoke, his voice sounded pathetically thin, “Something’s… wrong.”
Sonic blinked, completely caught off guard by Shadow’s honesty. “Uh, yeah,” he said quietly. “I kinda figured.”
Shadow gave a quiet huff that might have passed for a laugh if he had possessed the strength for it. “That's not what I mean.” He paused, brow knitting as he searched for the right phrasing. “It's... difficult to explain, but something in my body is wrong. I can feel it changing, and I don't know why." He pressed a hand against his chest fur, the faint glow under his skin flickering again. “The more I try to force it back under control, the worse it becomes. It feels like..." He hesitated. "...like something inside me is coming apart."
Sonic was silent for a moment, he just crouched lower, his eyes scanning Shadow’s form, ”Shads, what do you mean by ‘changing?’”
Shadow went still. His jaw tightened, the faint glow flickered brighter before he forced it down again. “I- it’s… complicated.”
Sonic frowned. “Complicated how? Are you sick? Hurt? Is it–“
”Sonic, please.”
“Do you need me to take you somewhere, or call someone? I can call Rouge, I don’t know if she’ll pick up, but I’m sure-“
“Sonic, enough.” Shadow’s voice cracked through the air like a blade. Sharp and final, harsher than he meant it to be. He saw Sonic’s mouth snap shut, the half-formed question dying instantly. Shadow looked down. “I don’t want to talk about it, and I don’t need help.”
The silence that followed was thick, pressing down on both of them.
Sonic sat back slightly, swallowing hard. His foot tapped against the floor, a nervous habit he probably didn’t even realize he was doing. He kept looking at Shadow like he was trying to read something that wasn’t there, like if he stared long enough he’d somehow understand.
After a long moment, Sonic exhaled slowly, “alright, you don’t gotta talk.”
Shadow blinked at Sonic, surprised by the lack of pushback.
Sonic just shrugged a little, “but what I do wanna know is, why didn’t you tell anyone? Rouge, Omega– hell, even me! If Rouge hadn't caught on, you would've been here all by yourself."
Shadow’s eyes flicked up, meeting Sonic’s gaze for just a second before dropping again.
“Because I can’t afford to be… weak.”
Sonic shook his head in disbelief, “You think letting yourself suffer alone in a corner makes you strong? You do know how stupid that sounds, right?”
Shadow didn’t argue. His shoulders sank, the tension finally slipping out of them. He was just too exhausted, “I didn’t know what else to do.”
Sonic’s expression mellowed. “Alright, here’s the deal,” he said, voice low but steady. “I’ll stay here tonight, and we can figure it out together. You can yell at me about it in the morning.”
Shadow's eyes lifted to him again, a flicker of surprise crossing his expression. He wanted to object, to tell Sonic to leave, to insist he had no need for anyone. It was the natural response he always defaulted to.
But the truth was, his body was burning out. His chest ached with every breath, and horrible things were crawling under his skin like a fire he couldn’t put out.
He didn’t have the strength to push Sonic away. Not tonight.
So instead, he exhaled slowly and let his head fall back against the wall. The faint glow beneath his fur, the energy that had been raging uncontrollably, began to dim. Finally, it faded to a soft, rhythmic pulse. For the first time in weeks, the chaos and pain inside him went quiet.

Sonic watched Shadow with a mix of worry and stubborn relief. The worst of the surge of whatever energy Shadow was trying to hold back had faded. Only the low hum of the vents and the faint glow from the city outside filled the room.
Sonic rubbed the back of his neck, glancing from the window to the crumpled figure on the floor.
”Alright, Shads,” he said lightly, “you need rest, I need rest, and you can’t sleep sitting here. You’ll wreck your back.”
Shadow didn’t answer, but he looked exhausted. No doubt from whatever pain he’s been suppressing for however long.
Sonic sighed. “C’mon, don’t bite my head off or anything, but I’m gonna pick you up, okay?” He waited a beat for the inevitable protest. But when none came, he crouched down and carefully lifted Shadow up bridal style.
And for a split second his breath caught. Shadow felt lighter. A lot lighter. His body, usually solid with coiled muscle and tension, now felt frail in Sonic’s hold. His gloves brushed over the ridge of bone at Shadow’s shoulder, much sharper than he remembered. He hadn’t noticed looking at him with the dim room and Shadow’s jet black fur, but he had definitely gotten thinner.
He immediately pushed that thought away, that was a problem for the morning. For now, Shadow just needed some rest.
“See? Not so bad.”
Shadow stirred faintly, muttering something that sounded suspiciously like a threat, but he still didn’t resist. Sonic laid him down on the bed, adjusting his body so it wouldn’t fall awkwardly to the side.
“There. Comfortable?”
“Barely,” Shadow mumbled, already halfway gone.
Sonic chuckled under his breath, trying to chase away the unease, “Figures. You’d complain in your sleep, too.”
Sonic paused once he’d gotten Shadow settled, eyeing the gloves still on his paws. For a second, he considered taking them off. It would’ve made sleeping easier, and way more comfortable, but the thought alone felt way too personal. Shadow would absolutely deck him for that when he woke up.
At least his shoes were already off. Shadow was lying there in just his socks, and Sonic silently thanked whatever cosmic force spared him from choosing between leaving Shadow’s shoes on the bed or risking his life removing them.
Yeah. He’d pushed his luck enough for one night. Knowing Shadow, he would’ve found a way to be mad about it no matter what Sonic did.
As soon as Shadow was tucked under the covers, he was completely dead to the world. Sonic hesitated a moment longer. He watched the slow, barely there, rise and fall of Shadow’s chest— like if he looked away, it might stop.
A heaviness settled somewhere within Sonic. The guy looked wrecked. His breathing was uneven, his fur was matted with sweat, and the faint pulse of red light still flickered beneath his skin like something was trapped and fighting to get out. Even when unconscious, Shadow looked like he was bracing for impact, like he couldn’t let his guard down even in his sleep.
Sonic wanted so bad to ask what had happened… what has been happening… to make the strongest person he knew just give up like this.
But more importantly, he wanted to help. Chaos, he wanted nothing more than to just take all of that pain away— to reach out, pull Shadow close, hold him, tell him it was going to be fine, and to make him believe it.
But that was a fantasy.
Shadow wasn’t the kind of person who let others hold him. He barely let people look at him, let alone comfort him. And Sonic, well, he wasn’t exactly great at this whole “quiet emotional support” thing either. So instead, he stayed where he was, watching from a distance. Protecting him the only way he knew how.
“Yeah,” he muttered under his breath with a humorless smile, “in my dreams.”
Still, his eyes lingered on Shadow a little longer before he turned towards the door.
Just to make sure he was still breathing.
The couch in Shadow’s living room groaned as Sonic dropped onto it, hands behind his head, eyes fixed on the ceiling. “Don’t worry, Shads,” he murmured to the dark, voice barely above a whisper. “I’ll keep watch tonight.”
Sonic settled deeper into the cushions and let the small apartment fall silent around him. Beyond the window, city lights glowed against the darkness, and the occasional car rolled quietly down the street, oblivious to the strange, heavy quiet that had settled inside.
