Main Masterlist | Whispers of the Gifted Masterlist

You weren’t recruited. You were assigned.

Born from a black-ops experiment the government quietly buried once the serum stabilized, you were a living weapon they kept in their back pocket. A contingency plan. When word came that the Avengers might need more muscle in the field, they didn’t ask. They deployed.

You didn’t come to make friends. You came to fulfill orders and win.

And yet, here you were, staring across the mat at Bucky Barnes, the Winter Soldier himself, while Sam smirked from the sidelines and Steve muttered something about “team bonding.” You were here to train, but Bucky had that look again that said you’re not welcome here.

“Again,” You say flatly, shrugging out your jacket and stepping onto the mat.

Bucky’s jaw ticks. “Thought you’d had enough yesterday when I put you on your ass.”

Your lip twitches. “I slipped.”

“Sure you did.”

He circles you slowly, assessing. His arms are relaxed at his sides but you’re not fooled. He’s reading your stance, waiting for your weight to shift, for your hips to square. You’d be insulted if you weren’t doing the exact same thing. You lunge first, test him. He blocks it easily, metal arm catching your strike mid-air. You twist, pivoting into a sweep that nearly clips his ankle, but he hops back with a grunt.

“Getting slower, Barnes,” You mutter.

“You talk a lot for someone who hasn’t landed a hit all week.”

The sparring sessions had started as training. Then they became contests. Now, it was just war. He didn’t like the way you fought. It was too sharp, too efficient. You didn’t like the way he looked at you, like he recognized something he hated in himself.

You fake going left and land a solid elbow to his ribs on the right. The air leaves him in a hiss. He recovers fast, but not fast enough to stop the cocky grin that pulls at your mouth.

“Gotcha.”

He narrows his eyes. “Beginner’s luck.”

He rushes you, sudden and aggressive. For a moment, you're toe-to-toe, exchanging blows with brutal precision. Metal arm meets gloved knuckles. You both move like predators. Mirrored, practiced, and too much history in your blood to fight sloppy. Eventually, you end up on your back, panting, his knee pinning your chest, breath hot against your cheek.

“Yield,” He growls.

Your fingers flex against the mat. “Not a chance.”

He hesitates for a beat too long and that’s when you slam your forehead into his nose. He yelps, a very undignified sound you wish you had recorded, and rolls off with a curse, cradling his face.

You scramble to your feet, wincing slightly from the impact. “You get distracted too easily.”

He looks up, eyes narrowed, blood trailing from his nose. “You’re insane.”

You toss him a towel. “Takes one to know one.”

For a moment, the room goes quiet, both of you catching your breath. Then he says, “They trained you like me, didn’t they?”

You don’t answer. You don’t have to.

“I can tell,” He continues, voice lower now. “You fight like you’re not allowed to lose. Like you don’t know what it means to stop.”

Your jaw tightens. “Then stop underestimating me.”

“I don’t,” He says quietly. “That’s the problem.”

The air shifts. Charged and uneasy as you both stand there, bruised and sweaty. Too close and too silent. Then Steve’s voice cuts in from the hallway.

“Good session, you two.”

You step back. Bucky wipes his nose. Neither of you says another word. But the next day, he’s already waiting on the mat before you get there. And he doesn’t hold back anymore.

The compound is quiet at midnight. The kind of stillness that wraps around you and presses into your bones. You slip into the kitchen in your sweats, body sore from training, head still buzzing from the adrenaline you never quite know how to shake. You don’t bother turning the lights on.

The fridge hums in the background. The tile is cold beneath your feet as you reach for the kettle. Then-

“You always drink tea like you're in a British spy movie, or is this just your midnight ritual?”

Your spine stiffens. You recognize the voice behind you, of course you do. But you don’t turn around, acknowledging him in a flat tone. “Barnes.”

“Didn't peg you for the insomnia type.”

You glance over your shoulder. He’s leaning in the doorway like he owns the room. Loose black t-shirt. Arms crossed. Shadows catch the angles of his face just enough to make his scowl look carved.

You gesture at the kettle. “Some of us have things on our mind.”

He steps into the kitchen, walking past you to open the cabinet above your head. You don’t move from your spot. He reaches over you, brushing against your shoulder on purpose, you’re sure. His body heat trails behind him like a warning.

“Stealing my tea now?” You ask flatly.

“You took my towel earlier.”

“You were bleeding on it.”

“I was using it.”

You roll your eyes and pour the hot water into two mismatched mugs. He raises an eyebrow when you slide one over.

“Poisoned?”

“Not yet.”

You both sip in silence as the fluorescent light over the sink flickers. He leans against the counter across from you, sipping slowly as he watches you. He always watches like he’s looking for something, maybe cracks in your walls.

“You always like this?” He asks.

You tilt your head. “Like what?”

“Walled off and sharp edges. Acting like you don’t need anyone.”

Your jaw tightens, resisting the urge to roll your eyes. “Better than acting like you used to be someone else.”

His expression darkens. The silence stretches. You should apologize, but don’t.

“Right,” He mutters, setting the mug down. “Guess we’re both good at pretending.”

You don’t look at him, but your voice comes quieter than intended. “Maybe we don’t know how to stop.”

He hesitates, and you notice something shift in his tone.

“You hit hard,” He says.

“You go easy on me.”

He scoffs. “I don’t go easy on anyone.”

You glance up at him. “Then maybe I hit harder than you expected.”

His lips twitch, just slightly. “Maybe.”

You stand there for a moment, two supersoldiers in the dead of night, staring at each other over mugs of tea like it’s some kind of game neither of you knows the rules to.

Then he says, voice lower now, “You’re not like them.”

You blink. “Them?”

“Soldiers. The ones they send. You’re colder, smarter. Meaner.”

You smirk. “Flatter me some more, Barnes.”

“I’m saying I know what it feels like to be made for war and expected to act like a person afterward.”

Something sinks in your chest. Deeper than you want it to.

“You think I’m not a person?” You ask.

He looks straight at you. “I think you’re trying real hard not to be.”

That lands too accurately. Way too close to the bone. You grip the mug a little tighter. He notices, but doesn’t push.

“I’m going to bed,” You mutter, setting the mug down.

As you pass him, his voice follows.

“Don’t forget tomorrow. Training at seven.”

You pause in your tracks, glancing back at him with narrowed eyes.

“You trying to kill me?”

“No,” He says with a ghost of a grin. “If I was, you’d already be dead.”

You smirk just a little. “Maybe you’re getting slow.”

His smile fades, but something warm lingers in his eyes.

“You wish.”

And for the first time, your heartbeat feels less like a threat, and more like a dare you don’t know whether to act upon.

-

The comms crackle in your ear as the wind howls around the rooftop. Rain slicks the concrete beneath your boots. Below, the city lights blur and flicker, distorted by smoke, shadows, and chaos.

The mission was to apprehend the target then turn them in. A simple in and out. Something you should have been able to complete with ease.

But you had been ambushed.

You skid across the rooftop, breathe ragged, blood sticky under your ribs. Something’s broken, probably more than one thing, but you don’t stop. You can’t.

Bucky’s voice cuts through the storm as he calls your name, sharp and commanding, “You’re heading for the west corner. That fire escape’s blown out. Stop moving.”

You ignore him. Every second wasted is another second the target might vanish. You need to cut them off. You need to move.

“Damn it—”

The roof crumbles under your weight. You drop.

It’s not far, three stories, maybe, but pain flares bright as you hit a ledge hard, the edge of it catching your side with a crunch. You roll, barely catching yourself before you slide off completely.

And then he’s there. Hands on your arms. Dragging you up, fast, rough, and angry.

“What the hell is wrong with you?” Bucky’s face is too close, eyes wide, rain streaking through his hair. “You were told to pull back!”

“I had them!” You wheeze, swallowing the metallic taste of blood. “We can’t let them run-“

“You can’t breathe.”

You try to shake him off. He doesn’t let go.

You hiss, teeth gritting, “I didn’t need your help.”

“That’s not what it looked like when you were halfway to death’s door.”

His grip tightens on your arms, but it’s not pain he’s trying to inflict. It’s panic he’s trying to hide. His metal hand is cold from the rain and trembling just slightly. You hate that you notice.

You turn your face away. “I’ve survived worse.”

“That’s not the point.”

“Then what is it?”

“That I care, damn it!”

The words slip out hot and ragged, louder than the rain.

You freeze and so does he.

The only sound for a moment is the wind, and your breath, shallow and uneven between you. His hands drop away from your arms slowly, like he’s just realizing he touched you at all.

He backs up a step. “Forget it.”

You stare at him, stunned. Blood is still soaking through your shirt, but your heart is thudding hard behind your ribs and not from the pain.

“You care,” You echo quietly, almost like a question.

He exhales, clearly frustrated and embarrassed. “Forget I said anything.”

“I didn’t think you did.”

“I didn’t want to.”

You look at him. Really look. There’s a flicker of something soft beneath all that steel. Vulnerability edged with guilt. It’s the one of the first times he’s looked at you without his guard up. It’s one of the first times you’ve looked at him without wanting to hit him.

“You should’ve let me fall,” You whisper.

He shakes his head. “No. I shouldn’t have.”

He pauses for a moment before adding:

“And I wouldn’t have.”

You say nothing as he steps closer. He doesn’t touch you this time. Doesn’t need to. But his voice drops to a murmur only you can hear, “You don’t have to keep proving you don’t need anyone. I already know you don’t. But that doesn’t mean I’m going anywhere.”

You hate how much it rattles you. You hate that you believe him. You lower your gaze to your hand, still bloodied, still shaking slightly from adrenaline.

When you speak again, your voice is barely audible.

“Help me back up.”

He does.

This time, his hand stays in yours longer than necessary. And neither of you lets go first.

-

You hate medical bays. Always have. Sterile light. Quiet beeping. That faint scent of alcohol and regret. You had shooed away the staff, saying you could do it yourself and would call if you needed anything.

You sit on the edge of the bed, shirt peeled halfway off, bruises blooming violet-black across your ribs, blood crusted at your temple. You’ve already tried to patch yourself up, but your hands won’t stop shaking and the gauze keeps slipping.

Bucky walks in without knocking.

You glare up at him. “Ever heard of privacy?”

He tosses a med kit onto the table and takes off his jacket. “You lost that privilege when you almost threw yourself off a roof.”

You scoff, but don't argue.

He opens the kit, pulling out antiseptic and gauze, and stands between your knees without asking. You don’t stop him even though you should, his admission earlier still echoing in your mind.

He dips the cotton in alcohol. “This is going to hurt.”

“I’m not new.”

He raises a brow. “Then stop flinching.”

You open your mouth to snap something back but he presses the soaked cotton against the gash on your side before you can, and pain sparks like electricity up your spine. Your hand shoots out instinctively and grips his arm. You feel the muscles tense under your fingers.

“Still not flinching?” He murmurs.

You grit your teeth. “Screw you.”

His lips twitch, barely.

The silence that follows is tight and thick, like something fragile stretched to the edge of breaking. His hand moves gently now, slower, wiping away blood. His touch is careful in a way that makes your chest ache more than your ribs.

You glance up at him. He’s too close. And he’s not looking at the wound anymore, he’s looking at you.

You could lean in. Just a little. You could close that impossible space and finally… you don’t. He doesn’t either.

Instead, he murmurs, “You don’t take care of yourself.”

You look away. “Don’t need to.”

“Bullshit.” His voice is low. Angry. Not at you, at whatever taught you to think like that. “You treat your body like it’s disposable.”

“Maybe it is.”

The silence that falls after that isn’t the kind you fill. It’s the kind that hurts.

He gently presses a bandage against your ribs, then tapes it in place. His fingers linger on your skin for a moment longer than necessary.

“You’re not disposable,” He says quietly. “Not to me.”

You freeze. There he goes again.

The air shifts. Then you do something you didn’t expect, you reach out and touch his jaw. Just two fingers, gently as if to test the weight of your own choice.

He doesn’t pull away. But he doesn’t move closer, either. You draw your hand back like the moment never happened. But it did.

“I’ll change the dressing tomorrow,” He says, voice rough.

“I’ll be fine,” You reply, just as quiet.

He turns to leave before stopping in the doorway.

“You don’t have to keep doing things alone,” He says without turning around, and then he’s gone.

You sit there for a long time after. Holding your breath like it’s the only thing keeping you from falling.

-

As time passes and you’re assigned to go on more missions, the tension between you and him builds for better or worse.

You had recently returned from a solo mission. The compound is quiet, but the air inside the training room crackles with something volatile. You slam the door behind you, furious.

And he’s already there. Bucky’s pacing with his gloves off and shirt clinging to his back. His jaw is tight and his hands are fisted like he’s been holding back from punching something or someone.

“I told you,” He growls, not even looking at you, “Not to go in alone.”

“I handled it.”

“You were shot.”

“I’ve been shot before.”

He spins on you, blue eyes wild. “That doesn’t mean it’s fine!”

You throw your bag down, with a frustrated sigh. “Why do you even care, Barnes?”

He’s on you in seconds; closer than he should be, breathe sharp with adrenaline and frustration.

“Because I’m tired of watching you bleed for people who wouldn’t do the same for you!”

“You think I don’t know that?” You snap. “You think I don’t feel that, every time I’m stitched up in some cold-ass medical bay while everyone else celebrates the win?”

His face is stone, but his eyes… God, his eyes are raw.

“Then why?” He demands. “Why keep doing it? Why keep throwing yourself at the fire when you know no one’s coming to pull you out?”

You try to shove him hard, but doesn’t move. You hate that he cares. You hate that he can’t just ignore you and view you as a tool like everyone else. When you go to answer, your voice is loud and it cracks:

“Because I don’t know how to stop!”

There it is. The silence after that is explosive. You’re both breathing hard, staring at each other. Daring the other to say something that will break the last barrier you’ve both kept between yourselves. That fragile, stupid boundary you’ve both pretended exists.

He takes a step forward and you match him.

His voice drops, dangerous. “You think I don’t see it? How you act like you hate me, just to keep from admitting you don’t?”

Your heart kicks into your ribs. “You don’t know anything.”

“I know you fight me harder than you fight anyone else.”

“Maybe because you deserve it.”

His jaw flexes. “Or maybe because you’re scared.”

“Of what?”

“Of wanting something real.”

You watches you flinch like he hit you, but he doesn’t back down. “You act like I’m the enemy, like pushing me away makes you stronger, but every time you fall, you look for me. Don’t lie.”

You swallow hard. “Don’t act like you don’t do the same.”

You’re chest to chest now. The air is boiling. You can feel the heat coming off his skin. Your hand is still curled in the fabric of his shirt from when you shoved him, but you haven’t let go.

He looks at your mouth and you look at his. The moment stretches before it breaks.

“You want to hate me?” He breathes. “Then say it.”

You stare at him, trembling now.

Say it, You tell yourself. End it. Push him away for good.

But the words won’t come. Instead, you whisper, too soft, too vulnerable:

“I don’t.”

That’s all it takes.

His mouth crashes into yours like a dam breaking. Like something starved, angry, desperate. You kiss him back just as hard, fingers in his hair. His hands grips your waist, then your back, then your face like he’s afraid you’ll disappear if he doesn’t hold all of you at once.

It’s not gentle. It’s not clean. It’s everything you’ve both tried not to feel. But it’s real.

When you finally pull back, barely, his forehead rests against yours. No words are shared. Just slow shaky breathing and the terrifying, undeniable truth:

You don’t hate each other. You never did.
