Sam, by now, is more or less familiar with Bucky's habits. It's out of character enough that even he's got an eyebrow arched, but Bucky's prone to the occasional bout of moodiness and it's easy to chalk this up to that. Especially considering he's just gotten out of solitary confinement, and Sam doesn't know that his time spent there was anything less than a chore.

He spends the rest of the day dodging in odd places; back of the library, smoking side of the yard, anywhere Steve isn't just to force some space between them for a while. Obviously that can't last, not when they share a cell, but any time he can get to put some distance and perspective into this he gladly takes.

He's almost expecting it to go unnoticed, too, but Steve is Steve and he wastes no time with the commentary. He's already on the top bunk by the time Steve arrives, book in hand and glancing over the top of it. God, you attractive son of a bitch.

"Good thing you know better," Barnes comments, a touch wryly because it's easier to play it off that way.
