Sebastian Stan imagines!

I'm my worst nightmare.

You immediately awoke when the opposite side of the bed dipped, and a low groan sounded from Bucky's side. You eyed him carefully, wondering if his dream had triggered Winter.

It had been three months since Bucky had tried to kill someone, and so far it's been Steve, Tony, or Sam. Never you, it was like Bucky knew that something would happen when it was going to be you, and on those nights he'd disappear into the training room, and hit as hard as he could.

"Bucky?" You whispered, setting a hand on his shoulder. He immediately reacted, pulling your arm behind your back and pressing into your shoulder.

"Okay, you're not Bucky." You groaned as you slipped from out of his grasp. He slammed you down on the ground, bringing black spots to your vision.

"James, it's me. Look-I know, I know you don't wanna hurt me." His dark eyes looked lifeless as you stared into them, trying to pry his fingers from your throat.

"B-Buck..Look at me." He snapped your arm away, literally causing it to snap in two places. You couldn't scream, but the pain was very, very much demanding to be felt.

"James, it's me. It's Y/N, your girlfriend."

"You're nothing to me, but my mission." Black spots were becoming clearer and clearer and by the time you had lost too much air, Bucky was knocked out, and you fell to the ground.

Two days later, 9 am.

Pain. That was all you felt. It was shooting up your face and right arm, but you could barely remember why you were in so much pain.

"..Bucky..?" You rasped, attempting to sit up, but Bruce came into your line of vision and pushed you back into the bed. "Don't get up, Y/N. You're not stable enough yet."

You felt your powers glitch, your body warming up, then returning to a freezing state. The state you were only in when you were sick or worried.

"What-What happened? Where is everyone?"

"Barnes lost control." With those three words, everything came flooding back. Bucky slamming you to the ground, then against the wall, fracturing your arm, and choking you to the point of unconsciousness.

"Oh my god, he - is he okay?"

"They're out looking for him now. Have been for the last two days." You slowly processed his words. "I've been out two days?"

"Yeah. Bucky brought you here when he regained consciousness, then he took off. They just made it to Siberia today."

Siberia. Where Bucky was held. Why would he go back there?

"I gotta help them- They're...He's too far away." You shivered. You'd also remembered that since you met Bucky, every time he was too far away from you, your powers would begin to turn to ice instead of fire, freezing you from the inside out. No. No, this was not a benefit.

If you froze, You died.

"I know you have some sort of connection to Bucky, but your arm is fractured in two places, you've got three broken ribs, and a dissolving concussion. You're gonna have to do your best to track him while I put you in a cast."

You groaned as he moved your bones back into place, and wrapped it in a white cast material, so that you could draw whatever you wanted on it.

"Bruce, get me on their comm."

"Y/N! How're you feeling?" You smiled at your brothers enthusiasm.  "I could be better, Sam,"

"We got a lead on Bucky from some workers in Siberia, so we're checkin it out." Steve added. "How're you feeling?"

"Like Banner's doing all this work on me for nothing.." You were freezing, and this was just the beginning of it. "You're not gonna die, Y/N." Natasha started.

"Bucky wouldn't do that to you." Tony added. "He's way too in love with you."

"Well, the feeling's mutual." You hissed as you felt the bruise on you neck, in the mirror there were two handprints around your neck, blue and bruising badly.

"Guys, please find him. Check everywhere you can, okay?" You were beginning to worry. What if Bucky was so focused on getting away that he'd forgotten the connection you shared? What if he felt so guilty he ended up hurting himself? He left, You thought. But what if he didn't agree that that was punishment enough?

"We're doing our best, I promise. You'll be alive and warm when we get back." Sam's voice somewhat calmed you down, your heart no longer beating fast as it was.

"You're going to be alright. I promise you."

2 am, Compound.

"Is she okay? Y/N!" You pulled the blankets up to your neck, and smiled at Sam.

"Are you okay? How're you feeling?" You shrugged, it immediately turning into a shiver. "I've s-s-seen better d-d-days."

"God, you're freezing." Cap frowned as he felt your forehead. "You're not feeling any better?"

"I-I w-was f-fine earlier. H-he h-had b-been here. B-but now, he's-he's so far away." Your teeth chattering drove Tony insane. He hated that Bucky would do this to you. He hated that you would let him. He knew that if you died that he would also, but he wouldn't risk Steve or anyone else falling into that depression.

"You're coming with us tomorrow. So we'll find Bucky and Give you a chance to get some warmth up in the air, alright. We'll get closer to Bucky, and all this will be okay." Tony ordered. He was not going to let the girl he thought of as his daughter die.

"O-okay."

"We leave at Eight."
