Intro
The first thing that tips you off isn’t the pain—it’s the wrongness. Your hands won’t stop shaking. Not from fear, not exactly, but from something building under your skin, like your body is bracing for a storm it somehow remembers.
The hallway stretches too long in front of you, lights humming too loud, every sound stacked on top of the next until your head starts to throb. Then your wrist pops. You gasp, clutching your arm as heat surges through your veins, sharp and electric. Your knees buckle, boots scraping against the floor as you barely catch yourself against the wall.
Hey—
The voice is immediate. Familiar. Panicked in a way you’ve never heard before. You look up, vision swimming, and see your dad at the far end of the hall. James Buchanan Barnes—former assassin, super soldier, unshakeable force of nature—is staring at you like the ground just dropped out from under him.
His eyes flick to your hands. To your fingers curling inward, nails darkening, lengthening just a fraction too much.
Oh no, he breathes.
Another jolt tears through you, deeper this time, rippling up your arms and down your spine. You cry out as your shoulders tense, muscles tightening on their own, your heart slamming so hard it feels like it might crack your ribs. “Dad,” you manage, but the word comes out strained, edged with something rough and unfamiliar. Bucky is moving before you even finish speaking.
Okay, he says quickly, holding his hands out, voice steady but tight.
Okay, it’s happening. I need you to listen to me.
Your hearing sharpens suddenly, painfully. You catch the distant echo of footsteps, the whisper of air through vents, the metallic whirr of his arm as it locks into place. The world feels closer. Brighter. Too much.
“I don’t—I don’t know what’s wrong,” you say, though some part of you already does. Your spine arches without permission, a sharp crack sending white-hot pain blooming across your back. You gasp, fingers digging into the wall as something shifts beneath your skin, rearranging you from the inside out.
Panic surges, wild and uncontrollable. Bucky reaches you just as a low sound rumbles out of your chest. You freeze. So does he.
Neither of you recognizes the noise—not really—but Bucky’s jaw tightens as understanding slams into place. He’s seen monsters before. He’s fought them. Contained them. But this one has your eyes.
It’s your first shift, he says quietly, certainty locking into his tone even as fear flickers across his face.
I didn’t think it’d happen like this.
Another wave hits, stronger. Your clothes pull tight across your shoulders. Your senses explode outward, every smell and sound crashing into you at once. Your instincts flare—run, fight, protect—and it takes everything you have not to bare your teeth. Bucky grips your arm, firm but careful.
Hey. Stay with me. You’re still you.
Your gaze snaps to his, pupils blown wide, breath coming fast. For half a heartbeat, something inside you snarls at the proximity. Bucky doesn’t let go.
I built a cell, he continues, already guiding you down the hall.
Reinforced. Safe. Just for this. But we gotta get there before you fully turn, okay?
Your legs tremble as another sharp crack runs through them, pain spiking, balance faltering. You cling to him, nails digging into his sleeve as the world starts to blur at the edges. “I’m scared,” you whisper.
I know, he says, voice rough, pulling you closer.
I’ve got you.
The heavy door comes into view—steel, thick, unyielding. A promise and a threat all at once. Your heartbeat roars in your ears, instincts clawing louder now, furious at being contained, desperate to finish what your body has started. Bucky tightens his grip, metal hand steady against your back.
I’m not losing you, he mutters, more vow than words.
Not today. Not ever.
As the door opens and the change surges forward, unstoppable now, one truth burns through the fear— Whatever you’re becoming, you’re not facing it alone. And this is only the beginning.
