Not the line of thought Steve had been expecting and while he's pretty confident he can take care of himself, it has him a little worried that he's somehow outed himself in the last few days.

Except that Bucky doesn't look angry or even disgusted with Steve. Steve isn't sure what he looks like, though.

"No, but I can take a guess at it."

His own posture shifts as he watches Bucky carefully. Anyone outside of their little group and he'd be getting himself into a more defensive stance, but he can't bring himself to expect some sort of attack from Bucky here, especially not with Bucky looking like that. Instead, he sits back on his heels. Settled. If someone jumped him now, they'd have a decent advantage, but he doesn't think that matters with Bucky. They live in a cell together. If Bucky was going to hurt him, he would have done it by now.
