Chapter 1: The Metal Hand Remembers
The hum of the Avengers compound was a low, constant thing, a thrum through the floor that vibrated in the plates of Bucky’s left arm. He leaned against the wall of the briefing room, a shadow in the corner where the light from the holographic displays didn’t quite reach. The oak table was a relic, scarred from the slam of fists and the scrape of weapon prototypes. Today, it held just one thing: a plain manila folder, its edges charred black.
“So, the short and tragic version,” Tony Stark said, pacing in front of a glowing world map. A single red dot pulsed in a remote stretch of Siberian tundra. “Satellite intel, declassified Russian military chatter, and a very chatty former Hydra payroll accountant we have in a pleasant little safe house in Vermont all point to the same lovely vacation spot. A Hydra cryo-research facility.Frozen assets, literally.Thought they’d scrubbed it. They didn’t scrub it well enough.”
Steve Rogers stood with his arms crossed, a solid monument in tactical gear. “What’s the objective, Tony?Intel?Retrieval?”
“Containment. Sterilization.” Tony tapped the air, and the hologram zoomed in on the dot, resolving into a blurred schematic of a bunker buried deep under permafrost.“The ice is melting. The security systems are failing.Whatever—or whoever—they left on ice down there could wake up. We go in, we download whatever’s left on their servers, we collapse the entry shafts, and we leave zero trace.A quick in-and-out.Twenty-four hours, tops. I’ll even buy the shawarma afterward.”
Bucky’s eyes were on the singed folder. He knew that particular shade of black.It came from the same kind of accelerant Hydra used to burn their dead.
“Standard team?” Steve asked.
“You, me, Natasha if he’s back from Cairo, maybe Wilson for air support.Minimal footprint.” Tony flicked his hand again. “Might be some cryo-pods.Probably empty. But just in case there’s a popsicle with a pension plan, we should have someone who speaks the language.” He didn’t look at Bucky. The room got very quiet, save for the electronic hum.
“What language is that, Tony?” Bucky’s voice was flat, a gravel road stretched too tight.Tony stopped pacing. He finally looked over.“The one where you don’t ask questions. The one on the mission logs.” He gestured, and a string of code flashed beside the bunker schematic—a file header. “This is all we’ve got from the Vermont fairytale.Most of it’s corrupted. But there’s one visual that survived the purge.”
He opened it.
A photograph bloomed in the center of the room, grainy, washed in the green hue of old security footage. It showed a laboratory, all sterile steel and snaking cables. In the foreground, a young woman was strapped to a medical gurney.She couldn’t have been more than twenty. Black hair stuck to her temples with sweat. Her eyes, wide and vivid blue, were staring directly into the camera, brimming with a terror so raw it felt fresh.
Bucky’s breath left his body.The world narrowed to those eyes.The humming in the floor became a roar in his ears. The scent of ozone and frozen earth flooded his sinuses, not memory but a full-body recoil. His left hand clenched, the servos whining softly in the quiet.
“Her name was Sage Vance,” Tony said, his tone clinical now, a tour guide in a museum of horrors.“Lead geneticist’s daughter. Theorized by Hydra to have inherited some latent… potential.They brought her in for observation. According to the fragment, she was their prime candidate for the next round of cryo-stasis.The file ends there.”
No. Bucky’s mind screamed it.The file didn’t end.He knew how it ended.He was there.
The memory didn’t come as a flashback, but as a reality overwriting the present. The sterile lab smell became the tang of old blood and antiseptic. The holographic glow was the cold fluorescence of overhead lights. He felt the chill of the chamber, the weight of the rifle in his right hand, the passive chill of the metal arm.
The Asset stood at the foot of the gurney. The girl strained against the leather straps, her head lifting off the thin pad.“Pozhaluysta,” she whispered, the please a cracked thing. Her eyes, those devastating blue eyes, locked onto his. They didn’t see the mask, the armor.They saw him.They begged him.
The order was a flatline in his inner ear.Terminate the subject.Cleanse the chamber.His metal hand rose. It was not his hand.It was a tool. It moved to her throat, the cool vibranium plates a grotesque parody of a caress against her frantic pulse.Her skin was warm. She made a small, choking sound. A tear traced a path through the grime on her cheek.He was supposed to squeeze.To crush.A quick, efficient deletion.
He didn’t squeeze.His fingers hesitated.A micro-second.A glitch in the programming.
A voice barked in Russian from the observation deck above.A reprimand. The order repeated, more urgent.His hand tightened.Just a fraction. He felt the delicate architecture of her trachea begin to yield. Her eyes widened, not with fear now, but with a heartbreaking, final understanding.Her lips formed a word without sound.Why?
Then the blast doors at the far end of the lab exploded inwards.Al Klaxons shrieked.Red light flooded the room. Overwatch was screaming about an incoming Allied strike.The order changed.Secure the primary research drive. Evacuate the level.The Asset’s hand snapped back from her throat as if burned. He turned, shouldering his rifle, and moved toward the data core, the programming reasserting its cold flow.He did not look back. He left her there, strapped to the table, gulping in ragged, sobbing breaths, the echo of his metal fingers still printed on her skin.“Barnes?”
Steve’s voice.Bucky blinked. The briefing room swam back into focus.His right hand was splayed on the cool tabletop, palm sweating. His left was still clenched, a fist of solid metal.He could still feel the ghost of her pulse against the plates.
Tony was looking at him, head tilted.“You alright? You’re looking a little… pre-2009.”
“I’m fine,” Bucky ground out. It was the oldest lie in the book.“You know the place,” Steve said, not a question. He’d been watching, reading the minute ticks of tension in Bucky’s jaw, the way his eyes had gone vacant and haunted.Bucky nodded once, a sharp jerk of his chin. “I’ve been there.”
“Great.So you know the best way in. Any structural weak points we should avoid?” Tony asked, tapping the schematic.Bucky pushed off from the wall. He walked to the hologram, his movements too precise, too controlled. He ignored the schematic, his eyes fixed on the frozen image of Elara Volkova. The guilt was a physical sickness, a lead weight coiled in his gut.He remembered every name on his list. But some of them… some of them he remembered in color.In sound.In the feel of their pulse under his hand.
He had left her there. In the chaos, amidst the explosions and the frantic evacuation, he had followed his new orders.He had never known what happened to her. He’d assumed the strike had buried the facility, and everyone in it.But the file was here.She was listed as a candidate. The ice was melting.
“The weak point,” Bucky said, his voice low and rough, “is the central cryo-bay.West wall. Supports were compromised during the shelling.” He finally turned to look at Steve, then Tony. The dread was a cold stone in his chest, but beneath it, something else ignited—a terrible, necessary resolve. “I’m going on this mission.”
Tony opened his mouth, probably to make a quip about babysitting, but one look at Bucky’s face killed it.Steve just gave a single, slow nod.
“You sure?” Steve asked.Bucky’s gaze returned to the girl in the hologram. To her pleading blue eyes.He had walked away once.He had followed orders.Not this time.
“I have to,” he said, and it was the only truth left in him.
“I have to,” he said, and it was the only truth left in him.
The plan formed with a brutal, surgical speed.Bucky’s intel on the structural weaknesses was the key. They’d breach through a secondary ventilation shaft on the west side, one he remembered as a maintenance crawlspace, now likely collapsed but more easily cleared than the reinforced main doors.
“It’ll be a tight fit for the suit,” Tony said, manipulating the 3D schematic, his fingers moving through the glowing lines.“Then you go in the undersheath.Minimal armor. We’re not expecting a standing army, we’re expecting… rust.” Steve’s voice was steady, but his eyes kept flicking to Bucky, who had retreated back into his corner, arms crossed tight over his chest.
“We need someone who can handle… non-physical barriers,” Bucky said quietly, not looking at anyone.“In case there are psychic dampeners. Or if she’s…”
He didn’t finish.Couldn’t.“Wanda,” Steve concluded. “She’s back.She’ll go.”
Tony nodded.“Fine. Recon trio: Barnes, Maximoff, and yours truly in the party suit lite. Rogers and Wilson provide overwatch at the shaft entrance. We find her, we secure her, we get the data, we blow the place back to the Stone Age.Emotions stay in the quinjet.Understood?”
They all understood. Especially the part about emotions.
The Siberian wind was a living thing, howling across the tundra and knifing through even the advanced polymers of their gear. The quinjet was a ghost against the endless white, landing miles out. Their approach was a silent trudge through deepening twilight, the facility nothing but a faint, unnatural hum under the wind.
The shaft was exactly as Bucky remembered, and that was the worst part. The grate was pried open, the darkness within smelling of cold metal and stale, chemically-treated air.A memory flashed: dragging a body bag through this same tunnel. He shook his head, the motion sharp.
“Ladies first,” Tony murmured, his face illuminated by the soft blue glow of his repulsors. The Iron Man armor was stripped down to its essential plating—a sleek, gunmetal grey skeleton.
Wanda went next, her crimson energy a gentle pulse that warmed the frozen air for a second. Then Bucky, dropping into the darkness without a word, his metal hand finding familiar rungs in the shaft wall.Inside, the facility was a tomb. Ice glistened on rusted pipes.Broken monitors littered the floor.Their footsteps echoed in a way that felt accusing. Tony’s scanners painted a map on their HUDs, leading them deeper, toward the central cryo-bay.They passed empty pods, their glass frosted and cracked.The silence was oppressive.
Then the map indicated a divergence: a sealed corridor leading away from the main lab block. A solitary cell.The security here was different—heavier, older. A single, rusted steel door with a small, barred window at eye level.Bucky moved forward first. His breathing, which he’d kept deliberately even, hitched. The memory was a sharp, physical pain behind his eyes: blue eyes, staring, begging. He raised his right hand, the flesh one, and pushed the door.It was unlocked.It swung inward with a scream of dead hinges.
The cell was a concrete cube. The air was cold enough to see, and it stank of mildew and a fainter, more biological decay.A thin pallet lay in the corner. On it, a form.Sage.
She was curled on her side on a simple, stained mat, wearing nothing but a torn and filthy hospital gown that did little to cover her. Her hair, once dark and sharp, was a matted veil across her face. Her skin, where it was visible, was the color of old paper, stretched tight over bone.Bucky’s stomach plummeted.The world tilted. This wasn’t a ghost from a file.This was a woman, reduced to a breath.
Tony’s breath caught audibly over the comms. The glow from his arc reactor seemed to dim, as if bowing to the horror in the room.
Wanda, behind him, gasped softly, a sound of pure, wounded empathy.At the noise, Sage stirred. A shiver racked her frame.With a effort that seemed to cost her everything, she lifted her head a fraction. The movement was agonizingly slow.The matted hair fell away from one side of her face.
Those blue eyes, now clouded with exhaustion and a depth of suffering that hollowed out Bucky’s soul, blinked slowly. They focused, drifting past Wanda’s glowing hands, past the stark figure of Iron Man, and landing on him.On the man with the metal arm.
Recognition did not flash.There was no energy for that.But her gaze held his. A weak, confused, animal misery.She opened her mouth.Her lips were cracked. A thread of sound emerged, so faint it was almost stolen by the hum of the failing lights.
“You…” she whispered, the word breaking. “You came back?”
The words hung in the frozen air, a fragile accusation that pinned Bucky to the spot. His throat closed. Every rehearsed explanation, every pathetic fragment of an apology, turned to ash. She didn’t sound angry. She sounded lost. Like a child who’d been promised a rescue that was seventy years late.
Wanda moved first, a swirl of scarlet energy and compassion that cut through the shock. She knelt beside the pallet, her movements deliberately slow. “Shh,” she murmured, her voice a soft contrast to the industrial groan of the facility. “You’re safe now. We’re getting you out.” Crimson light wreathed her hands, not a threat but a gentle warmth that began to seep into the air around the shivering woman.
Tony’s helmet retracted with a faint hydraulic hiss. The usual sarcasm was absent from his face, replaced by a stark, clinical assessment that couldn’t mask his horror. “Jesus Christ. Life signs are minimal. Severe hypothermia, advanced malnutrition. She’s running on fumes.” He glanced at the empty nutrient IV bag hanging from a rusted stand, the tube still attached to a port taped to her skeletal arm. “The support systems failed weeks ago. She shouldn’t be alive.”
But she is, Bucky thought. She stayed alive. The will that must have taken was a magnitude of suffering he could barely fathom.
Sage’s eyes, still locked on Bucky, fluttered at the warmth from Wanda’s power. A full-body shudder racked her, so violent it seemed her bones might snap. Her breath hitched, a wet, dangerous sound in her chest.
“We need to move her now,” Tony said, his voice low and urgent. “A thermal shock blanket from the pack, Barnes. Gently.”
The command broke Bucky’s paralysis. He shrugged off his pack, his metal fingers fumbling with the catch. The sound of the servos seemed obscenely loud in the small space. He pulled out the dense silver blanket and stepped forward, unfolding it.
As he leaned over, his shadow fell across her. She flinched, a tiny, instinctive recoil that was worse than a scream. Her cloudy eyes darted from his face to the glint of his left arm, her breath coming quicker, shallower. She was remembering the cold touch of it. He could see the memory surface, a terror more immediate than the freezing cell.
He froze, the blanket held out like a peace offering he had no right to give. “I’m not gonna hurt you,” he said, the words raw and utterly insufficient.
“You need to let Wanda and I handle this, Buck.” Steve’s voice was calm in his ear, the comms a thin tether to the present. “You’re a trigger. Step back.”
Bucky didn’t move. He couldn’t leave her looking at him like that, like the monster from her last waking memory. He met her gaze and did the only thing he could think of. He lowered himself slowly, deliberately, until he was crouched beside her pallet, putting himself below her eye line. A gesture of submission. Of non-threat.
“I’m sorry,” he whispered, the words meant only for her. They weren’t for what he did then. They were for leaving. For every day of the seventy years she spent in this dark, frozen hole because he walked away.
Her confused stare held his. The panic in her eyes churned, mixing with exhaustion and a deep, uncomprehending ache. Her cracked lips parted.
“Cold,” she managed, the word a puff of vapor. It wasn’t forgiveness. It was a simple, devastating report from a body pushed beyond its limits.
“We know,” Wanda said softly. “We’re going to make you warm.” She looked at Bucky, a silent instruction. He laid the blanket over Sage’s legs, moving with a sniper’s cautious precision.
Tony was scanning the room, his jaw tight. “No data core here. Just this. A holding cell. They left her.” The disgust in his voice was palpable. “They stuffed their pockets with hard drives and left the evidence to die. Neat.”
As Wanda gently worked the blanket up, Sage’s hand twitched—a pale, skeletal thing against the filthy mat. Her fingers trembled, then stretched, not toward Wanda’s comforting glow, but toward the dull sheen of Bucky’s metal wrist where his glove had ridden up.
He stopped breathing.
Her fingertips, ice-blue and delicate, brushed the plates. It wasn’t a caress. It was a confirmation. A terrible recognition. She traced a seam, her touch lighter than a ghost, and her eyes flooded with a clarity that was worse than the confusion.
“The Machine,” she whispered, the name curling from her lips like a curse learned in a forgotten language. The memory was whole, and it was ugly. The fear sharpened, focusing into a razor point of trauma. Her breath hitched again, but this time it spiraled. A ragged inhale caught in her ruined lungs, and a low, broken keen escaped, building into a weak, breathless cry of pure animal terror.
“No, no, shh, it’s okay, you’re safe,” Wanda soothed, her power pulsing brighter, trying to cushion the mental avalanche.
But Sage was drowning in it. She tried to push herself away, her strengthless limbs scrambling against the mat. “Ne zapuskayte yego! Ne dayte yemu…” Don’t start it up. Don’t let him…
“Barnes, back off. Now.” Tony’s voice was a command.
Bucky rocked back on his heels, his heart a hammer against his ribs. He was causing this. His presence was a wound. He stood up, turning his back to her, squeezing his eyes shut against the sound of her fractured sobs. The guilt was a physical compression, collapsing his lungs.
Suddenly, the entire facility groaned. A deep, metallic shriek echoed down the corridor, followed by a distant crump of collapsing concrete. Dust sifted from the ceiling.
“Overwatch, report,” Tony snapped, his helmet sealing back over his face.
“Seismic activity,” Sam’s voice crackled over the comms. “Minor, but it’s unstable. The detonations from the old strike… the integrity’s going. You’ve got minutes, not hours.”
“Plan,” Steve’s voice cut in, steady and decisive. “Tony, you carry her. Wanda, you shield them from any falling debris. Barnes, you’re on point. Clear the path back to the shaft. Move.”
The mission parameters crystallized, a clean objective in the moral chaos. Extract the asset. But she wasn’t an asset. She was a person he’d broken, and he was the wrong one to lead her to safety.
Tony moved in, the repulsors in his palms glowing a soft, neutral blue. “Okay, ma’am. Gonna have to lift you. It might feel strange.” His mechanical voice was gentler than Bucky had ever heard it.
Sage was still trembling, her cries reduced to silent shakes, her eyes wide and fixed on the ceiling as if waiting for it to fall. As Tony’s arms slid under her, she went rigid, a small, choked sound escaping her.
Bucky forced himself to move. He strode to the cell door, his rifle snapping up, scanning the dark corridor. The red dot of his laser sight painted a trembling path on the opposite wall. Every sense was hyper-alert, the soldier overriding the man. This was something he could do. He could fight the physical enemy. The crumbling walls. The closing darkness.
He could clear a path.
“Let’s go,” he said, his voice the Winter Soldier’s flat monotone. It was the only voice he trusted not to break.
He stepped into the corridor, leading them back into the belly of the beast, the sound of her ragged breathing and the whir of Tony’s suit following close behind, a haunted procession fleeing a grave that was desperate to keep them.
