"Never had leave..." Well, of course if he steps back and thinks about it, that makes sense. But it's one of those things where he probably wouldn't have realized if Finn hadn't pointed it out, and he feels a little stupid for that.

He can't help it, he rests his hand on Finn's shoulder again. Tempting to hug him, but he's trying to be careful, respectful, all of that. He just got a big reminder that Finn hasn't exactly had a normal life; stuff Poe thinks is casual might not be for him. "Well. We'll just have to make your first real leave great when it rolls around."
