“Black Eye Inside”
Dean had been off since breakfast.
Not loud about it. Not dramatic. Just wrong in small, irritating ways that stacked up like unpaid bills.
He’d poured his first cup of coffee, taken one sip, and declared it “weak as hospital tea,” then immediately poured a second and third like caffeine was a personal challenge. He rolled his shoulders like something pinched at the base of his skull, cracked his neck twice, and muttered that the bunker mattresses were “actively trying to murder his spine.”
By ten a.m., he’d eaten half a sleeve of saltines straight from the box and glared at Sam for finishing the peanut butter.
“You had half the jar,” Sam said.
“Yeah, well, I wanted the other half,” Dean shot back, already reaching for water like his mouth had turned to sand.
Cas watched all of it quietly from the war room table. The stiffness in Dean’s movements. The way he kept pressing his thumb into the muscle just under his skull. The flicker of irritation that wasn’t entirely aimed at anyone.
By noon, Dean was standing over the map table, palms braced against the wood, staring down at the world map like it had personally betrayed him. His gaze wasn’t fixed on one place — it drifted unfocused across continents, lines blurring, coastlines shifting in a way that made his stomach twist.
“Why is it doing that?” Dean muttered.
Sam didn’t look up from the lore book in his hands. “Doing what?”
Dean blinked.
The inked lines of the map shimmered.
At first it looked like heat rising off asphalt. Then the edges split. Broke apart. Jagged silver zigzags ripped across his vision, bright and electric, cutting through everything like someone had drawn lightning directly into his eyeballs.
Dean straightened slowly.
“What the hell—”
He reached for the table and missed it by several inches.
Cas was on his feet instantly, catching him by the arm before gravity did.
Dean jerked away on instinct. “I’m fine.”
“You are not,” Cas said, steady and certain.
The zigzags intensified, spreading outward in pulsing arcs, violet and white and wrong. It felt like welding sparks exploding behind his left eye.
Dean squinted hard. It didn’t help. It made it worse.
The pain didn’t build. It slammed into him all at once — sharp and brutal — like someone had driven a railroad spike through the left side of his skull and kept twisting, the pulse of it syncing perfectly with his heartbeat.
Dean gasped. Actually gasped.
The overhead lights felt like interrogation lamps now. The low electrical hum in the bunker walls roared like a jet engine.
“Lights,” he hissed, voice tight. “Kill the damn lights.”
Sam moved fast. The room dropped into shadow, only the faintest emergency glow along the baseboards remaining.
Even that was too much.
Dean pressed his palm hard against his temple like he could physically hold his skull together.
“Dean?” Sam’s voice shifted — that edge creeping in.
“It’s just a headache,” Dean snapped, because that was easier than saying I can’t see right.
The smell of old paper from the bookshelves suddenly turned sour in his nose.
The next wave of pain hit and folded him in half.
He barely made it down the hall before he was on his knees in the bathroom, gripping the sink as nausea crashed over him hard enough to steal his breath. He retched until there was nothing left, until even dry heaving felt like it was splitting his head open wider.
Cas knelt beside him without speaking. One hand steady between his shoulder blades. Human. Warm. Solid.
Dean slumped back against the cold tile afterward, sweat dampening his shirt, skin pale under the fluorescent light that now felt like acid against his eyes.
Cas reached to dim it further.
Dean squinted up at him, eyes glassy. “Don’t.”
“Don’t what?”
“Don’t look at me like that.”
“Like you are in pain?”
“Like I’m fragile,” Dean ground out.
Cas held his gaze evenly. “You are in pain.”
That wasn’t the same thing. Dean knew it. He just didn’t like hearing it.
Sam’s phone rang in the hallway.
The name on the screen was enough: Jodi.
Sam answered, pacing, voice low. Cas could hear pieces. Missing hikers. Fresh tracks. Sioux Falls forest. Something moving at night.
Wendigo.
Sam stepped back into the doorway, torn straight down the middle.
Dean heard enough. He always did.
“Go,” Dean muttered, dragging himself up by the edge of the sink.
“Dean—”
“Sam. Go.” He wiped his mouth with the back of his hand. “I’m not dying. Yet.”
Another pulse detonated behind his eye and he sucked in air sharply, fingers digging into the porcelain hard enough that his knuckles blanched.
“I can stay,” Sam insisted.
“And let Jodi deal with a damn Wendigo alone?” Dean snapped, then winced immediately because raising his voice felt like getting stabbed from the inside. “Go. I’ve handled worse than a headache.”
That part wasn’t entirely a lie.
Cas stood slowly. “I will remain.”
Dean snorted, though it came out weaker than he intended. “Fantastic. Florence Nightingale with a trench coat.”
Cas didn’t blink. “I do not own a nurse’s uniform.”
A beat.
“And I have not worn the trench coat since I fell,” he added flatly. “It seemed unnecessarily dramatic.”
Sam huffed despite himself, then sobered. “Call me. If anything changes. Anything.”
Dean waved him off. “Yeah, yeah. Go save the world.”
When Sam left, the bunker shifted.
It always did when one of them was gone. The air felt heavier. Sealed. Like a submarine diving deeper.
Dean pushed himself upright and nearly blacked out.
Cas caught him before he hit the floor.
Dean shoved at his chest, more reflex than strength. “Stop catching me.”
“You are unstable.”
“I’m fine.”
“You are not even vertical.”
Dean glared.
The glare lasted about half a second before the pain spiked again and he squeezed his eyes shut.
“Son of a bitch,” he muttered, breathing shallow.
Cas stayed close but didn’t crowd him.
Dean swallowed hard. His voice dropped lower now, stripped of some of its volume but not its edge.
“I take care of everyone,” he said. “That’s the job. Sam. You. Jodi. Claire. I don’t need a damn babysitter hovering over me because my head’s throwing a tantrum.”
Cas stepped closer anyway.
Calm. Unmoved.
“Unfortunately,” Cas said evenly, with the faintest hint of something dry under the surface, “your head is currently winning.”
Dean shot him a look.
Cas met it without flinching.
“And,” Cas added quietly, “you do not get to decide you are alone in this simply because you dislike needing help.”
Dean’s jaw tightened.
Another pulse rolled through him — slower now, deeper — and his shoulders sagged a fraction.
He hated that Cas could see it.
“I’m not helpless,” Dean muttered.
“No,” Cas agreed softly. “You are human.”
The words hung there between them, heavy as the bunker walls.
And the migraine was just getting started.
Dean’s room stayed dark.
Cas had taped over the thin strip of light under the door and unplugged anything that hummed unnecessarily. The bunker still breathed in the walls — ventilation, distant generators — but he’d reduced it to the lowest tolerable existence.
Dean lay on his side, one arm over his eyes like he was shielding himself from artillery fire.
“Still loud,” Dean muttered.
“It is quieter than before.”
“Feels like a jet engine.”
Cas didn’t argue. Migraines distorted perception. He’d read that twice already.
Dean shifted.
Instant regret.
“Damn it—” He sucked in air sharply, fingers digging into the mattress. “Feels like someone’s using my skull for target practice.”
Cas pressed a cold washcloth against Dean’s temple.
Dean flinched, then leaned into it despite himself.
“Too cold?” Cas asked.
“No. Just… everything’s too much.”
His voice was tight. Thin around the edges.
Cas adjusted the cloth slightly, moved slower than usual. Every motion deliberate.
“You can take ibuprofen,” Cas said quietly. “Or naproxen. We have both.”
Dean cracked one eye open. Immediately regretted it. “Don’t start.”
“It is not ‘starting.’ It is medication.”
“I’ve had worse.”
“Yes,” Cas said mildly. “You have also had stab wounds. That does not mean you should ignore those.”
Dean huffed. It turned into a pained exhale halfway through.
“Don’t hover.”
“I am sitting.”
“You’re hovering emotionally.”
Cas paused.
“That is not a measurable position,” he said dryly.
Dean would’ve smirked if his face didn’t feel like concrete.
Another wave rolled through him — slower now but deeper, like pressure building behind bone. He sucked in air and curled tighter.
Cas didn’t reach for him immediately.
He waited.
When Dean’s breathing went ragged, Cas moved the cold cloth to the back of his neck.
Vasoconstriction, he’d read. Cooling could reduce blood vessel dilation. Might dull the pounding.
Dean exhaled shakily.
“…Okay,” he muttered. “That’s not terrible.”
Cas allowed himself a small, quiet victory.
The nausea crept back in. Dean swallowed hard.
“I swear to God,” he muttered, “if I puke again—”
Cas already had the trash can within reach.
Dean noticed.
“Stop being prepared.”
“No.”
Dean shifted again, testing the limits.
The pain answered immediately.
“Son of a— this is stupid. I take care of people. I don’t lie around like some damn invalid.”
Cas didn’t snap. Didn’t lecture.
He simply adjusted the pillow slightly so Dean’s neck wasn’t strained.
“You are not an invalid,” Cas said calmly. “You are experiencing a neurological event.”
“Don’t medical-term me.”
“You asked me not to hover emotionally. This is factual hovering.”
Dean made a noise that might have been a laugh if it didn’t hurt so much.
Silence settled.
Dean’s breathing gradually slowed. The worst spikes were passing. The throb remained, but it wasn’t detonating anymore.
His hand moved blindly across the mattress.
Found Cas’s sleeve.
Didn’t grip hard this time. Just held.
Cas stayed still.
Minutes passed.
Dean’s body loosened, inch by inch.
Eventually, exhaustion won.
Dean fell asleep mid-breath, still faintly frowning like his brain hadn’t gotten the memo that the war was over.
Cas stayed there a moment longer.
Then carefully, gently, he eased his sleeve from Dean’s hand.
The bunker library glowed blue in the dark from Cas’s laptop screen.
He hated that this was what it came down to now.
Search bars. Medical articles. Forums.
Migraine with aura. Acute treatment. Prevention.
He read fast. Methodical.
Immediate treatment options:
- NSAIDs: Ibuprofen. Naproxen. Acetylsalicylic acid.
- Triptans: Sumatriptan. Naratriptan. Almotriptan. Prescription required.
- Antiemetics: Domperidone. Metoclopramide. Help with nausea and absorption.
- Dark, cool, quiet room — already done.
- Cold compress — working.
- Small amounts of caffeine at onset — strong coffee, possibly with lemon.
- Ginger for nausea.
He opened a document and began typing.
Not because he enjoyed lists.
Because this was something he could control.
If migraine returns:
- Immediate darkness.
- Cold compress on temples/neck.
- Ibuprofen at first sign.
- Strong coffee early — not after peak.
- Ginger tea for nausea.
- Monitor duration and frequency.
- Doctor appointment. No debate.
He stared at the last line for a long moment.
Doctor appointment.
Dean was going to hate that.
Cas added another section.
Long-term prevention:
- Consistent sleep schedule.
- Regular meals. Not coffee and saltines.
- Hydration.
- Cardio exercise (Dean would argue. Sam would win).
- Stress management.
- Identify triggers.
- Reduce caffeine dependence.
- Possibly magnesium supplementation.
- Consider relaxation techniques (this would require Sam-level patience).
Cas leaned back in the chair.
There had been a time he would have placed two fingers on Dean’s forehead and ended this in seconds.
Now he was learning about biofeedback and ginger root.
It felt small.
It felt human.
It felt like not enough.
He closed the laptop and returned to Dean’s room.
Dean had shifted in his sleep, one arm sprawled toward the empty side of the bed like he was checking whether someone was still there.
Cas sat down again.
Dean stirred faintly, sensing the mattress dip.
Without opening his eyes, he moved closer.
Cas adjusted the blanket.
Stayed.
And when Dean’s fingers curled loosely into his shirt again, Cas let them.
Morning — or whatever passed for morning underground — settled over the bunker without ceremony.
No sunrise. No birds.
Just the steady hum of systems and the faint smell of old coffee somewhere down the hall.
Dean was awake before he moved.
The pain was still there, but different now. Not the spike. Not the lightning. Just a deep, heavy bruise behind his left eye — like he’d taken a solid punch straight to the skull and now had a black eye on the inside.
He stared at the concrete ceiling.
“You still here?” he asked, voice rough with sleep and dehydration.
“Yes.”
Cas didn’t answer from the hallway.
He answered from beside the bed.
Dean turned his head slightly.
Cas was sitting in the chair he’d dragged close during the night. Same spot. Same posture. He hadn’t retreated to the library. Hadn’t vanished. Hadn’t disappeared into distance the way he used to.
Just stayed.
“You didn’t even smother me with a pillow,” Dean muttered.
“I considered it briefly.”
Dean snorted softly. It hurt. He stopped.
Cas handed him water.
Dean took it without protest. Small sips. Careful.
“That sucked,” Dean said after a moment.
“Yes.”
“I hate not being in control.”
“I am aware.”
Dean studied him.
“You didn’t leave.”
“No.”
“You used to.”
Cas didn’t pretend not to understand.
“Yes.”
Silence stretched.
“There was a time,” Cas said evenly, “when I would have healed this with a touch.”
“Yeah. Angel mojo.”
“Yes.”
Cas held his gaze.
“I do not have that anymore.”
Dean waited.
“I cannot end your pain with grace,” Cas continued. “I cannot override what your body is doing. I cannot fix it instantly.”
Dean’s jaw tightened slightly, but he didn’t interrupt.
“But I stayed,” Cas said simply. “I stayed in this room. I adjusted the lights. I kept the noise down. I counted the minutes between doses. I made sure you did not fall when you tried to prove you could stand.”
Dean huffed faintly at that.
“I researched,” Cas added.
Dean groaned. “Of course you did.”
“I made a list.”
“Oh, God.”
“There are preventative measures.”
Dean squinted at him. “You’re not putting me on yoga.”
“That will likely require Sam’s involvement.”
Dean closed his eyes briefly. “Traitor.”
The corner of Cas’s mouth moved — barely.
“I cannot heal you with grace,” he said more quietly. “But I can learn. I can adjust the lights. I can measure medication timing. I can identify triggers. I can remain.”
That last word landed steady.
Dean opened his eyes again.
“You didn’t disappear,” he said.
“No.”
“You didn’t vanish the second it got messy.”
“No.”
Dean swallowed.
“You were scared,” he said quietly.
“Yes.”
“Because I was in pain?”
“Yes.”
Dean let that settle between them.
“You’re pissed.”
“Yes.”
“At me?”
“No.”
Cas’s voice didn’t waver.
“At the fact that I am limited. At the fact that I have to use search engines and cold cloths instead of power.”
Dean studied him carefully.
“You weren’t useless,” he said.
Cas tilted his head slightly.
“You stayed,” Dean repeated. “Right here. Didn’t bolt. Didn’t ghost.”
Cas exhaled slowly.
“I am human,” he said. “This is what humans do.”
Dean looked away for a moment, jaw working.
“I don’t like needing people,” he admitted.
“I know.”
“I don’t like people seeing me like that. Bathroom floor. Can’t see straight. Can’t even stand.”
“You were in pain,” Cas replied evenly. “Not weak.”
Dean’s eyes flicked up sharply at that.
Something shifted.
“If you’ve got the guts to stay,” Dean said slowly, voice rough but steady, “even when I’m a nightmare… even when I’m not the guy holding everything together…”
Cas didn’t interrupt.
Dean’s hand slid across the mattress — not grabbing. Choosing.
“Then I guess I’ve got the guts to stop pretending this is just team crap.”
The air tightened.
Dean looked straight at him now.
“I don’t do halfway,” he muttered. “If you’re staying, you’re staying. Not as some cosmic roommate. Not as backup.”
Cas felt something settle inside him. Solid. Certain.
“I am staying,” he said quietly.
Dean nodded once.
“Yeah,” he said. “Then don’t act surprised.”
He reached up, hand sliding to the back of Cas’s neck. Firm. Grounded.
And then he pulled him down.
The kiss wasn’t rushed.
It wasn’t fragile.
It was deliberate. Solid. Dean pressing his mouth to Cas’s like he was setting something in place and daring it to move.
Cas kissed him back steadily, one hand bracing against the mattress, the other curling into Dean’s shirt.
No light.
No miracle.
No grace.
Just choice.
When they parted, Dean rested his forehead against Cas’s.
“I still don’t need a babysitter,” he muttered.
“Noted.”
A beat.
“But,” Dean added quietly, “you can stay.”
Cas didn’t look away.
“I am not going anywhere.”
