Bucky appreciated the space even if the practical side of him couldn't help silently commenting about the apparent lack of safety consideration therein. After all, what if he was, say, an assassin?

(Realistically he acknowledged that David didn't seem naive enough to let just anyone go traipsing about his home, but he still found himself evaluating his surroundings for advantages and possible ambushes.)

David's return came with a once-over, a simple head to toe scan that was force of habit now. Bucky's lips quirked slightly at the mug and at the easy way David navigated the space. Compared to scientists who looked at his arm with the glee of a child given a new toy, the casual ease was welcome.

"Functions as an arm," he replied, though the joke fell a little flat. Truly Bucky didn't try too hard for levity, too busy studying the other man for a clue behind his words. "What do you mean, uncomfortable?"
