"Thank you." Quiet, steady. At the reassurance. Which isn't quite what he asked for... and is, at the same time, very much what Steve would do, if it came to that.

But then, finally, Bucky looks down. "Nobody has to tell me, Steve. I know what I've done, and to how many. If it were just about anyone else..."

If it were almost anyone else, there wouldn't be reassurance. There would be working to neutralize him and put him behind bars. Not that any bars can make a difference to seeing their faces in his dreams.
