Work Text:
Nobody was supposed to know about the safehouse. That was the point of it, a nothing apartment above a nothing bakery in the old part of Split, chosen because it wasn't the kind of place anyone would look for Captain America, the Winter Soldier, and Hawkeye. It wasn't even supposed to be a mission, not really. Three days verifying a HYDRA remnant cell before what was left of SHIELD got involved, and then home.
Steve had the layout of the building memorized inside an hour of arriving, the way he memorized everything, out of habit more than necessity. Clint had the street mapped from the rooftop across the way, counting foot traffic patterns, clocking the same grey sedan that circled the block twice in forty minutes and once more an hour after that. Bucky noticed it too. He didn't say anything at first. He just moved his chair a few inches so his back wasn't to the window.
"You're doing the thing," Steve said, not looking up from the file he was annotating.
"What thing."
"The thing where you get quiet and start planning six exits out of a room that's only got two."
"Three," Bucky said. "There's a vent."
Peter had arrived that afternoon, wired and delighted in the specific way of a fifteen-year-old who had just spent two days touring university engineering labs and was now getting to be in the same building as actual, real Avengers, a fact he seemed constitutionally unable to stop mentioning.
"Happy said you guys would only be here like a day," Peter said, trailing Bucky into the kitchen. "Is that, like, a coincidence, or does Mr. Stark just schedule things around you on purpose."
"Ask him," Bucky said, not unkindly, digging through a cabinet that held exactly one box of stale crackers and nothing else. "This country doesn't believe in real breakfast food, by the way. I checked three bakeries."
"There's literally a bakery under us."
"Croissants aren't breakfast, they're a suggestion." Bucky glanced over, caught the kid grinning at him, and felt something loosen in his chest despite the job, despite the sedan outside, despite four decades of learning not to get comfortable in rooms with only two exits. "You eat yet?"
"I had a granola bar on the plane."
"That's not eating, that's surviving. Sit down, I'll find you something that isn't crackers."
It was, by every account any of them gave afterward, an unremarkable, almost pleasant afternoon. Which was, in its own way, the worst part. None of them saw it coming, not even Bucky, who had spent seventy years learning to see everything coming, and who would spend a long time after blaming himself for the half second he'd spent laughing instead of watching the door.
The gas came through the vents. Not the kitchen vent Bucky had clocked, but a second one none of them had mapped, tucked behind a support beam in the stairwell where Peter and Bucky had drifted, mid argument about whether pastries counted as breakfast. It hit fast and it hit wrong, some enhanced compound that scrambled Bucky's senses in a way tear gas never had, that dropped him to one knee with his ears ringing before he'd even registered a threat. He heard Steve's voice shout something from the other room, heard the crash of a door being kicked in, heard Clint's bow clatter to the floor somewhere above him. He got one hand on Peter's arm, some instinct older than thought telling him to keep the kid close, and then the world folded in on itself and went dark before he could do anything with that instinct at all.
He came to on a concrete floor with his wrists bound behind him and no memory of how he'd gotten there, which hadn't happened to him since Wakanda, and which scared him more than he wanted to admit.
The cell was geay, low ceilinged, windowless, lit by a single bulb that buzzed at a pitch that set Bucky's teeth on edge. There was a bolted chair in the centre of it, empty. There was a door with a keypad. Steve was awake before he was, already working uselessly at the restraints, some vibranium weave that wasn't giving an inch no matter how he pulled. Clint was awake too, a cut bleeding sluggish above one eyebrow, cataloguing the room with the flat professional stillness of a man doing math in his head.
Peter was still out.
"Kid," Bucky said, low, watching him. "Hey. Peter."
It took him a long moment to surface, longer than any of them liked, and when his eyes finally opened they were glassy and unfocused before they cleared. "Where," he started, and had to stop, swallow, try again. "Where are we."
"Working on it," Steve said, voice level, the sound of a man deciding not to let anyone see him afraid. "You hurt anywhere? Anything feel broken?"
Peter did a slow inventory, wincing. "Just, everything hurts a little. Head mostly."
"That's the gas," Clint said. "Should ease off."
It did, faster than any of them thought to question that first day. There was too much else happening for anyone to clock the specific speed of it, a fifteen year old shaking off a chemical knockout agent in under an hour when the rest of them were still fighting the fog of it hours later. Nobody was looking for anything strange yet. There was nothing, in that first stretch of hours, to make anyone look.
He came in alone the first time, flanked by two guards who stayed at the door. Mid fifties, grey at the temples, dressed like a man who did other people's taxes for a living. Unremarkable in a way that made the hair on the back of Peter's neck stand up worse than shouting would have.
"You're the interesting one," Kessler said, and his eyes went to Peter and stayed there.
"He's fifteen," Steve said immediately, something raw under the command in his voice. "He's not part of this. Whatever this is."
"He's Tony Stark's intern," Kessler said, unhurried, still looking at Peter, "who was on a private jet, at a Stark Industries safehouse, in the company of three of Mr. Stark's closest associates, forty eight hours after Stark Industries quietly moved an eight figure sum into a trust that names no beneficiary." A small smile. "Mr. Stark doesn't do sentiment, gentlemen. He does strategy. So when a company famous for treating its intern program as a publicity stunt starts flying one specific teenager around on a jet built for board members, I find myself asking a simple question."
He crouched to Peter's eye level. "Whose son are you, really."
"I'm not." Peter's voice cracked on its own, no effort required. "I'm just his intern. I'm good at engineering. That's it, that's the whole thing, I swear."
"We'll talk more," Kessler said, unbothered, standing. "Teenagers are remarkably bad liars, once you've given them enough time to get tired." He looked at the other three in turn. "You have my numbers wrong if you think I want anything from you. Soldiers talk under duress the way rocks talk under duress. Eventually, and never anything useful. A scared kid protecting his father's secret is a much more efficient conversation."
He left. The door sealed with a heavy pneumatic hiss.
"He's wrong," Peter said, too fast. "I'm really not his, I'm not, I'm just some kid he's mentoring, that's the whole story."
"Nobody in this room needs convincing of anything," Bucky said. "That's not what this is."
"Then what is it."
Steve exhaled slow. "Leverage. He thinks you're valuable, either because you actually are Tony's kid and he can use you against him directly, or because Tony's protective of you regardless and that's leverage enough on its own. He's not going to stop asking. And he's not going to be gentle getting his answer."
"He's not wrong that hurting you gets Tony's attention," Clint said, flat, eyes on the door. "Doesn't matter what's true. Matters what he's decided to believe."
Peter looked down at his zip tied wrists and thought, with a clarity that felt like ice water down his spine, that the real secret, the one that would actually explain everything, was so much worse than the one Kessler was chasing that he would rather die than let it slip. He didn't say any of that. He just said okay, in a small voice, and let Bucky shift closer against his own restraints until their shoulders touched, a solid line of warmth that didn't fix anything but made the next stretch of minutes easier to survive.
They kept time by the meals, thin and grey and twice a day, and by the specific creak the floor made near the door when the guards changed shift. Steve worked the restraints every chance he got. Clint mapped the room the way he mapped everything, obsessively, silently, building something he clearly meant to use the second a gap opened. Bucky said less than either of them, but he'd taken up a spot nearest the door without seeming to decide to, and he kept it.
Peter tried to be useful in the ways that were allowed. Good ideas about the vent cover, quiet observations about the guards' rotation, the small currency of usefulness a scared kid was supposed to have. What none of them saw yet, because there was no reason yet to look for it, was the other work he was doing underneath all of that, the constant, exhausting effort of making sure his body didn't do anything his body wasn't supposed to know how to do.
It cost him more than the fear did, some days. Holding himself to human strength when his hands wanted to bend the bolt on the chair without trying. Flinching a half second late on purpose when a guard raised a hand, because flinching on time would mean flinching too fast, would mean a fifteen year old anticipating a blow the way a trained fighter did. He was fighting two battles at once from the very first hour, and only one of them had a villain standing in the room to fight it against.
Kessler came back on the second day, and this time it wasn't just talking.
They took Peter to the chair. Two guards at his shoulders, wrists bound to the arms of it, and Kessler pulled a second chair around backward and sat with his arms folded over the back, entirely relaxed, like a man settling in for a conversation he expected to enjoy.
"Who are you to Tony Stark," he asked.
"His intern," Peter said. His voice only shook a little.
Kessler nodded to a guard, unhurried, like ordering coffee.
Peter had braced himself for pain the way he braced for patrol going bad, the deliberate decision that his body would not give him away. What he hadn't braced for was how precise it was. Kessler wasn't interested in damage for its own sake. He wanted duration, the specific patient art of hurting someone in a way that kept the mind clear enough to keep answering, that never tipped over into pain so total it became useless. It was, in its own quiet way, worse than brutality would have been, because brutality ends. This didn't feel like it was going to end. It felt like it was going to keep finding new rooms inside him to move into.
The first few minutes were the worst in a strange, specific way, because his body hadn't learned yet how to survive this particular thing, hadn't built any scar tissue around it, and every new wave of it arrived like the first one all over again. He tried counting his own heartbeat to give his mind somewhere else to stand, the way he sometimes did hanging upside down off a building at 2 a.m. waiting for a mugger to make a move, except there was no building here, no rooftop, no easy escape a web line away. There was only the chair, and the buzzing light, and Kessler's calm, patient voice asking the same six words like they were the only six words that existed anywhere in the world.
Peter bit down on every sound his body wanted to make. Some got out anyway, thin and involuntary, and each one felt like a small defeat, a coin dropped into a jar he was trying so hard to keep empty. His enhanced senses, the same ones that let him hear a purse snatcher three blocks away or catch a falling toddler before anyone else in the room had registered the toddler was falling, worked against him now, sharpening everything, the scrape of the chair legs, the particular timbre of his own breath going ragged, the smell of the guard's aftershave too close to his face. There was no dulling any of it down. He just had to survive feeling all of it at full volume.
He thought, somewhere in the middle of it, distantly, almost calmly, that this was the strange cruelty of a healing factor built for punches and falls and the occasional building collapse. It hadn't been built for this. It didn't know how to make this shorter. All it could do was clean up the wreckage afterward, fast enough to be its own kind of problem, and leave him wide open and fully present for every single minute leading up to that.
He could hear his own pulse hammering in his ears, faster than it should climb this fast, and some detached corner of his mind catalogued that too, one more thing to hide, one more piece of himself he had to keep folded small and quiet where nobody could see it. Even here. Even now. Don't let it show. Don't let your body tell them what your mouth won't.
"Who are you to Tony Stark," Kessler asked again, patient, like no time had passed.
"His intern," Peter said, and this time his voice broke clean in half, and he hated how relieved he felt when Kessler finally nodded the guards off.
Kessler studied him a moment, head tilted slightly, the way a man studies a puzzle he hasn't solved yet but is starting to enjoy. "You're stronger than you look," he said, almost to himself. "That's interesting too."
"We'll try again tomorrow," he said, standing, brushing off his slacks. "Stubborn kid. Won't last."
They brought him back on unsteady legs, and Steve was up the second the door opened, and Clint was already moving to help lower him down. Bucky hadn't moved from his spot by the wall, jaw tight, eyes fixed on some middle distance that wasn't the cell.
"I'm okay," Peter said, which wasn't true. "Didn't tell him anything. Nothing to tell."
"We know, kid," Steve said, hands careful, checking him over.
Nobody said anything else about it that night. Nobody had a reason to yet. A scared kid holding out under pressure looked, from the outside, exactly like what it was supposed to look like: a scared kid holding out under pressure. It would take longer, and it would take something specific, before any of them started to wonder if there was more underneath it than that.
Underneath his shirt, in the dark, where nobody was looking, the worst of the bruising had already started fading from deep purple to a sickly yellow green, three days ahead of schedule. Peter felt it happening, the strange itching pull of it, and pressed his forearm hard against his own ribs, willing it to slow down, willing his body to just, for once, behave like everyone in that room expected it to.
It didn't.
It happened on the fifth night, and it happened by accident, the way these things always do.
Peter had woken from a doze with a scream half formed in his throat, some nightmare fragment of the chair and Kessler's patient voice, and before he was even fully conscious his hand had shot out and caught the metal water cup Clint had left balanced near his knee, catching it clean out of the air an inch before it hit the floor, no sound, no fumble, the kind of catch that took either luck or reflexes no fifteen year old had any business having.
Nobody said anything in the first stretch of silence that followed. Peter's own brain caught up half a second after his hand had, and he watched, with a sinking, sick feeling, the way Clint's eyes tracked from the cup in Peter's hand to Peter's face and stayed there.
"Lucky," Peter said, too fast, setting the cup down like it had burned him.
"Sure," Clint said, and didn't push it, not that night. But he didn't look away either, not for a long moment, and Bucky, who missed very little, noticed Clint noticing, and filed it away without comment.
Before any of that, there had been the fourth day, which none of them talked about much afterward, because it was the day Kessler stopped being patient and started being thorough.
He'd brought a second guard into the chair room that morning, and a folding table, and a set of instruments laid out with the kind of neat, deliberate spacing that told Peter, even before anything happened, that today was going to be different from the two sessions before it. Kessler didn't sit backward in his chair this time. He stood, arms folded, and let the guards do the opening work while he watched, quiet, patient, like a man auditing a process rather than running one.
It went on longer than the first two sessions combined. Peter lost the thread of time somewhere in the middle of it, the buzzing bulb overhead smearing into a long white streak whenever his eyes lost focus, which was often. His body did what it always did, tried to keep up, tried to knit closed what was being opened, and for the first time he felt the actual cost of that arms race in real time, a strange, sick, doubled sensation of pain and half healing running on top of each other, wounds trying to close even as new ones opened a few inches over, his whole nervous system caught in a feedback loop that had no clean edges to hold onto.
He held the line on the only thing that mattered. Not his name. Not the specific ache blooming in six different places at once. Just the two words that would end everything the second he let them out. Spider-Man. He turned them over and over behind his teeth like a stone he refused to spit out, and every time a sound tried to climb up past them, he swallowed the sound back down along with everything else.
Kessler noticed the endurance and read it as answer enough on its own. "You understand," he said, somewhere past the point Peter had stopped being able to track individual sentences cleanly, "that most grown men would have told me their mother's maiden name by now. Just to make it stop. You haven't given me anything. That tells me the thing you're protecting is worth more to you than your own comfort. Which tells me it's real."
Peter didn't answer. He didn't have the breath to spare on an answer. He just kept his eyes fixed on a scuff mark on the floor near Kessler's shoe and breathed, in through the nose, out slow, in through the nose, out slow, the same rhythm May had taught him years ago for panic attacks that felt, in hindsight, laughably small compared to this.
By the time they were done with him that day, he couldn't stand on his own, and the guards half dragged him back down the corridor, his bare feet scraping the concrete, and it took everything he had left, every scrap of will his fifteen year old body still owned, to keep his face arranged into something that looked like ordinary teenage exhaustion instead of what it actually was.
It might have stayed there, that one brutal but explainable day, if it had been the only thing that made the others start to wonder. It wasn't.
Two hours later, deep into the kind of quiet that made the whole cell feel like it was holding its breath, one of the guards shoved the door open harder than usual, and a loose panel of loose plating above the frame, already cracked from Clint's earlier probing, came free and swung down fast, right at Peter's head.
He didn't duck. He didn't have time to decide to duck. His hand came up on its own, caught the panel dead centre before it connected, and set it down against the wall as gently as if it weighed nothing at all, instead of the twenty some pounds of reinforced metal it actually was.
The silence that followed this time was different. Longer. Heavier.
"Peter," Steve said, very carefully, in the tone of a man choosing every word before he let it out of his mouth. "That panel should have put you on the ground."
"I got lucky," Peter said, and even to his own ears it sounded thin and small and nothing at all like the truth.
Bucky hadn't said a word, but Peter felt his eyes on him, steady and unreadable, and something about the quality of that silence, patient rather than accusing, was somehow so much worse than if he'd been shouted at.
"You've gotten lucky twice tonight," Clint said quietly. "I don't really believe in luck that specific."
Nobody pushed further, not then. Kessler's men were still doing their rounds outside, and there wasn't room in that cramped, dangerous silence for the kind of conversation this clearly needed to become. But Peter understood, with a dread that settled cold and permanent in his chest, that something had shifted in the room that couldn't be shifted back. They were watching him differently now. Not with suspicion exactly, not accusation, but with the specific, careful attention of people who had just started asking themselves a question they weren't ready to say out loud.
He lay awake a long time that night, staring at the buzzing bulb, and thought, with something close to despair: I have to be so much more careful now. I don't get to make mistakes like that again.
He didn't know yet that the mistakes were only going to get harder to prevent, the weaker his body got.
Bucky didn't sleep on the nights the lights dimmed low enough to pretend it was night. He sat with his back to the wall and his eyes half closed and let the others believe he was resting, and instead he turned the last few hours over and over, the cup, the panel, the way Peter's whole body had gone rigid with something that looked less like embarrassment and more like fear of being caught.
He thought about a different chair. Leather straps instead of zip ties, white tile instead of gray concrete, men who hadn't wanted information so much as compliance, who understood, the way Kessler seemed to understand, that patience did more damage than anger ever could. He remembered, with the specific unwanted clarity of memory that never properly healed, what it cost to decide, over and over, that he would not give them what they wanted, and to watch that decision worn down anyway, not because his will broke but because eventually there wasn't a self left organized enough to keep choosing.
He watched Peter, asleep now, twitching through some private nightmare against Steve's shoulder, and thought: there's something in him that's been trained to disappear the second it's noticed. I know what that looks like. I used to be that.
He didn't say it out loud, not yet. But he started watching the kid differently after that night, not with suspicion so much as recognition, the specific aching familiarity of a man who understood exactly what it looked like when someone was fighting a second war underneath the first one, invisible to everyone in the room except somebody who'd fought it themselves.
Whatever it is, Bucky thought, he's carrying it alone because he thinks that's the only safe way to carry it. I spent seventy years believing the same thing. I'm not gonna sit here and let a kid learn that lesson the same hard way I did.
The sessions got longer after that, and Peter's ability to hide what they cost him got shorter.
He noticed it first in small ways. A cut along his forearm, deep enough that it should have needed stitches, closing itself into a thin pink line before the guards had even finished walking him back to the cell, and having to sit on his hands, literally sit on them, to keep from letting anyone see the wound simply wasn't there anymore. A bruise blooming dark across his ribs in the chair, and by the time Steve got a look at him an hour later it had already faded to a sickly yellow that no ordinary bruise reached in under four or five days.
He started keeping his sleeves down even when the heat in the cell made everyone else strip down to undershirts. He started angling himself in the dim light so nobody got a clean look at his face right after a session, giving the worst of the swelling time to recede before anyone could clock how fast it was happening. It was its own kind of exhausting, running two systems at once, managing pain that was real and constant and managing the visible evidence of a body burning through that pain faster than it should. He was so tired, by day six, that the effort of hiding had started to cost him nearly as much as the injuries themselves.
Kessler noticed the fading bruises too, though he read them wrong, the way a man convinced of one story tends to misread every piece of evidence to fit it.
"You bruise light and clear fast," Kessler said, studying him on day six with something almost admiring. "Stark money buys good genetics, I suppose. Or good doctors on retainer. Either way, it tells me something. Ordinary interns don't come from stock this resilient."
Peter said nothing. His jaw ached too much to bother arguing a point that, for once, was working in his favor.
The physical toll kept climbing in ways that had nothing to do with Kessler at all. His body needed fuel to keep doing what it was doing, more of it than the thin gray paste twice a day could possibly supply, and by day seven the deficit had started to show in ways he couldn't manage or hide. His hands trembled between sessions now, not only from fear. He was cold constantly, a bone deep cold that had nothing to do with the actual temperature of the room. Twice he caught himself drifting into something that wasn't quite sleep and wasn't quite unconsciousness, a gray half state that scared him more than the sessions did, because it meant his body was starting to make decisions his mind wasn't part of anymore.
"He's healing wrong," he heard Steve say to Clint, low, in the tone adults use when they think a kid is too out of it to hear them. "Or not wrong. Fast. Too fast, and then he crashes hard right after. Watched him this morning. Split lip closed in under ten minutes and then he could barely hold his water cup."
There was a silence that felt, even through the fog Peter was drifting in, like several people arriving at the same uneasy thought at once and being afraid to say it first.
Kessler's patience thinned into something meaner as the days wore on. By day eight the sessions had stopped being conversations at all. He barely bothered with questions anymore, just watched, arms folded, expression unreadable, while the guards worked, and Peter understood, somewhere underneath the pain, that this wasn't about information now. It was about erosion. About how much time Kessler believed he still had before something in this equation broke.
There was no chair that day. They didn't bother walking him to the other room at all, which was its own quiet horror, doing it right there on the cell floor where Steve and Clint and Bucky had no choice but to hear every second of it through the thin wall Kessler's men dragged him behind, close enough that the sound carried, far enough that none of them could reach him. Peter understood, distantly, through the fog of it, that this was deliberate too. Kessler had learned, over a week, that hurting the boy in front of the soldiers cost him nothing extra and bought him something valuable: three grown men forced to sit with their own helplessness, forced to imagine the parts they couldn't see, which was so often worse than the parts they could.
His body had stopped keeping up somewhere around day six, and by day eight the gap between injury and healing had widened into something that frightened him more than Kessler did. Cuts that should have closed in minutes took an hour. Bruises stopped fading at all and just sat there, dark and stubborn, the way an ordinary person's would. He understood what that meant even through the haze of it. His healing factor was rationing itself now, the way a starving body rations its own fat and muscle, burning through whatever reserve it had left and finding less of it there every time it reached.
He counted, because counting was the only thing he had left to hold onto that wasn't pain. He counted his own breaths. He counted the seconds between one wave of it and the next, the way he used to count seconds between lightning and thunder as a little kid, except there was no storm passing here, nothing moving on to somewhere else. There was just Kessler's voice, quieter now, almost bored, murmuring instructions to the guards like a man directing a minor home repair. Peter fixed his mind on the one thought he had left the strength to hold onto, over and over, a single sentence worn smooth from repetition: they can hurt this body all they want. They don't get the other thing. They don't get to know what I am.
By the time it stopped, he wasn't entirely sure anymore where the cell floor ended and his own skin began. He heard, from a great distance, Bucky's voice on the other side of the wall, raw and furious, shouting something at the guards that had no words left in it at all, just sound, just rage with nowhere to go. He held onto that sound like a rope.
Afterward, dragged rather than walked back to the cell, Bucky caught him before he hit the floor and lowered him down with a care that felt entirely out of proportion to what Bucky Barnes was built and trained for. His hands were shaking, Peter noticed, distantly, through the fog. He'd never seen Bucky's hands shake before.
"Hey. Hey, look at me." Urgent under the calm. "You still with me?"
"Yeah," Peter breathed, though the room had gone soft and distant at the edges. "'M okay. Just tired."
"I know, kid." Bucky's flesh hand came up, brushed the damp hair back from his forehead. "I know you're tired. You've done so good. Whatever it is you're protecting, you've done so good."
Something in Peter's chest, wound so tight for so long, finally started to slip.
"Can't tell you," he mumbled. "If he finds out. If anybody finds out. It's not just me. It's everyone."
"Shh. Okay. Okay, you don't have to." Bucky's voice had gone rough. "You don't have to tell us a single thing you're not ready for. We got you. Just breathe."
Across the cell, Steve had gone very still, watching, Clint too, and Peter understood, distantly, that he had just handed them one more piece of a puzzle he had spent eight days trying to keep them from ever assembling. But nobody pushed. Nobody said the word that had started, quietly, to form behind three sets of eyes. They just let him rest, let him keep the last thin thread of it, and Bucky sat with a hand on his shoulder long after Peter had finally, mercifully, slipped under.
"It's not about money," Steve said quietly, once Peter's breathing had evened into something like real sleep. "Whatever this is. He's not scared of Kessler finding out he's rich, or finding out who his real father is. He said it himself. It's not just him."
"He heals too fast," Clint said, low. "You've seen it too, I know you have. That's not stress, that's not adrenaline. That's something else, and none of us have wanted to say the word out loud yet because it feels like it isn't ours to say."
Bucky was quiet a long moment. "Doesn't matter what it is," he said finally. "Whatever he's carrying, it's heavy enough that he'd rather die in that chair than let it out. I know what that kind of carrying does to a person. I've lived on the inside of it." His voice had gone flat and hard, the old soldier surfacing, unhurried and certain. "I'm not gonna sit here and wait for him to break under the weight of protecting the rest of us. We get him out. Whatever it costs."
"We've tried the restraints," Clint said. "Tried the vents. Tried the door seam. I've got nothing that isn't a guess dressed up as a plan."
"Then we make the guess," Bucky said. "I don't care what it costs. We've got maybe two, three more days before his body just stops keeping up, whatever the reason for that turns out to be. I'm not watching a kid run out of road because we sat here being careful."
Steve looked at him a long moment in the dark, something unspoken passing between two men who had survived enough of each other's worst days to read what wasn't being said out loud. "Okay," he said. "Then we watch every gap. Every rotation, every meal drop, every second that door's not sealed all the way. First real chance, we take it. All of us, together."
Nobody slept much after that.
The opportunity, when it came, wasn't clean. It never is.
A guard rotation ran half a minute long, a door stuck on its seal just slightly, just enough, and Clint, who had spent nine days doing nothing but watching, was already moving before anyone had fully processed the moment existed at all. What followed was fast and brutal and almost entirely silent, four people who between them carried decades of training in exactly this kind of violence, unleashed all at once against men who had gotten complacent, who had let themselves believe a bound Captain America, a restrained Winter Soldier, and an unarmed Hawkeye constituted a solved problem.
They were wrong.
Peter, weak as he was, found himself hauled upright between Steve and Bucky, moving on legs that barely held him, adrenaline doing what nine days of starvation and torture hadn't left him the resources to do alone. He caught, distantly, Kessler's voice somewhere down the corridor, sharp with real alarm, shouting orders nobody was fast enough to follow.
It wasn't a clean escape. Clint took a graze along his ribs that would need real stitches. Steve's knuckles were a ruin by the time they cleared the second corridor. But they moved as a unit, the way people who had trusted each other with their lives a hundred times over knew how to move, shielding the smaller body between them without any of them needing to say why that mattered so much.
Peter, half carried, felt the cold night air hit his face for the first time in nine days, and something in his chest broke open at the sheer relief of it, sky, wind, the smell of the sea somewhere beyond the compound wall, and then his legs gave out entirely and the world went sideways and dark.
"Peter." Bucky's voice, sharp with real fear now, catching him before he hit the ground. "Hey. Hey, stay with me, come on."
"He's crashing," Steve said, every trace of the careful calm he'd worn for nine straight days gone from his voice. "Clint, the beacon, now."
"On it." Clint already had the small emergency transponder out, the one Kessler's men had never found because Clint had kept it somewhere no pat down was ever going to reach, thumbing it to life with hands that weren't quite steady. "Come on, come on."
Bucky had Peter cradled against his chest, one hand pressed flat over the worst of the bleeding at his side, talking low and constant, the specific rambling nonsense people use to keep someone tethered. "Stay with me, kid. Come on. You held that line for nine days, you don't get to let go now, you hear me? Stay with me."
Peter's eyes fluttered, unfocused, fixed somewhere on Bucky's face. His lips moved, barely audible over the wind and the shouting behind them.
"Don't," he breathed. "Don't tell. Please. Can't. Know."
"I know, kid. I know." Bucky's voice cracked clean down the middle. "Nobody's gonna make you tell anybody anything. Just breathe. Just stay with me."
The extraction team found them nine minutes later, a blur after of noise and light and hands that weren't trying to hurt him for once. Peter drifted in and out through most of it, catching fragments. Steve's voice, raw, giving coordinates. Clint's hand gripping his own, steady even through the tremor. Bucky refusing to let go of him even when the medics tried to take him, until Steve said something low and urgent that finally got him to loosen his grip.
"Vitals are crashing," someone said, from very far away. "BP's in the floor, how long has he been running a fever like this."
"Nine days," Steve's voice, hoarse. "He's been like this for nine days and he never said a word."
"We need him in surgical in the next twenty minutes or we're not going to have the option," someone else said, and Peter, drifting somewhere just beneath consciousness, thought with a strange distant calm: oh. I might actually die.
He thought of May. He thought of Ned. He thought, absurdly, of a half finished chemistry assignment sitting on his desk at home, due a lifetime ago. Underneath all of it, stubborn and unyielding even now, he thought: don't tell them. Not even now. Especially not now.
"Peter." A voice close, cutting through the fog. Bucky, walking alongside the stretcher despite clearly having been told to step back. "Listen to me. You don't have to hold onto it anymore, okay? You held it long enough. Nobody in this world's gonna think less of you for letting go now."
"Can't," Peter whispered, barely audible, eyes fluttering shut despite every effort to keep them open. "Not safe. Not for anybody."
"Okay." Bucky's voice broke. "Okay. You don't have to. Just stay. Just stay, Peter, that's all I'm asking."
The last thing Peter heard, before the dark finally, fully took him, was the frantic rhythm of a heart monitor and Bucky Barnes' voice, low and wrecked, saying his name like a prayer.
Tony Stark did not sleep for the first thirty six hours after the call came in.
He had been in a briefing when the message reached him, three words from Steve relayed through a dozen layers of secure channel, we found him, and it had taken every ounce of control he possessed not to shove past four SHIELD liaisons and a security detail to get to a jet. What he found, when he landed at the field hospital outside Split, was a version of Peter Parker he had never once let himself imagine. Pale beneath a network of monitor leads, a ventilator doing work his own body had, for a handful of terrifying hours, simply been too depleted to do on its own.
"He crashed twice on the table," the surgeon told him, careful, clinical, the way people learn to be careful around Tony Stark when the news is bad. "Whatever he was running from, however long they had him, his body was operating past any reasonable threshold of endurance. We don't fully understand yet how he stayed conscious as long as he did."
Tony didn't say what he was thinking, which was that he understood exactly how. He had known for over a year what Peter carried underneath the intern story, had watched him limp into the lab more than once with injuries that healed too clean and too fast to be anything but what they actually were. Sitting in that too bright hallway with his head in his hands, he understood exactly what it must have cost a fifteen year old boy to keep that secret intact through nine days of exactly the kind of pressure designed to break it.
"He held the line," Steve said quietly, sitting beside him, still in the same torn, bloodied clothes he'd worn out of that cell, refusing every offer of a hospital bed of his own until he'd said this. "Tony. He never told them. Not once. Not even close to the end, when I don't think any of us would've blamed him if he had."
"I know," Tony said, voice cracking. "That's the whole problem. I know exactly what he was protecting, and it kills me that he thought it mattered more than his own life."
Bucky, leaning against the wall a few feet away, arms crossed tight over his chest like he was holding himself together by main force, finally spoke. "He kept saying it wasn't safe. That if anybody found out, it wasn't just him who'd pay for it." His jaw worked. "He was thinking about all of us the entire time he was falling apart. Fifteen years old, and he spent his last clear thoughts making sure the rest of us stayed safe."
Nobody said anything for a long time after that.
Peter woke on the fourth day in the ICU, disoriented, the ventilator finally gone, his throat raw, sunlight coming in soft and wrong angled through a window that told him, dimly, that time had passed in a way he couldn't account for.
May was there, gripping his hand so hard it almost hurt, her face wrecked in a way he'd only seen once before, a lifetime ago, in a different hospital. Behind her, Tony, standing at an awkward distance like he didn't trust himself to get closer, Steve, Clint with his arm in a sling, and Bucky, closest of all, sitting in a chair pulled right up against the bed rail like he hadn't left it in days, which, Peter would learn later, was more or less true.
"Hey, kid," Bucky said, voice rough. "There you are."
Peter's mouth was too dry to manage more than a rasp. "Did I." He swallowed, tried again. "Did I say anything? While I was out, did I tell."
"No," Bucky said gently, immediate, like he'd been waiting for that exact question, like he'd known it would be the first thing out of Peter's mouth the second he could form words at all. "No, kid. You didn't say a word. Not one. You held it the whole way through."
Something in Peter's chest, wound so tight for so long he'd almost forgotten what it felt like without it, finally, quietly, began to unspool.
"I was so scared," Peter admitted, barely a whisper, and it wasn't clear anymore whether he meant scared of Kessler, or scared of dying, or scared of the secret, or all three tangled into something too large to separate out. "I didn't want anyone to get hurt because of me."
"I know." Bucky's flesh hand closed, careful, around Peter's much smaller one. "I know exactly what that costs to carry alone. Believe me. I know better than almost anybody alive." His voice thickened. "But you're not alone anymore, okay? Whatever it is. Whenever you're ready, however long that takes, you don't gotta hold it by yourself. Not ever again."
Peter looked past him, at May's tear streaked face, at Tony standing there with an expression that looked, for the first time in Peter's memory, entirely undefended, and he thought, with a tired, aching relief that went bone deep: maybe not yet. But maybe, someday soon, I won't have to.
"Thank you," he whispered, to all of them, to Bucky most of all. "For not letting go."
"Never," Bucky said, and meant it with everything he had left. "Not once. Not ever, kid."
Outside the window, Split's late summer light kept falling, ordinary and indifferent, on a world that had no idea how close it had come to losing something it would never even know it had.
