Bucky Barnes

 Bucky wasn't sure what he was doing here, he knew Steve had been looking for him for months, he knew Steve wanted him to come home. He remembered the only problem is, he remembered everything.  But he was tried of running, he was tired of working in the shadows, he was dirty hungry and a little broken. 

So he raises his fist to the door and knocks, hoping there wont be an answer so he can just bolt.
