Peter / Tony
No one would blame Peter, for not being able to properly look at Tony. Not even Tony could blame him, even if it did hurt a little. Not that he was going to say that because look, Tony had learned to be pretty good at being parental the last few months and he was putting it into practice here. Or trying to.
He knew Peter healed faster than most and that he'd probably be fine without getting checked out, but that didn't mean he didn't worry or want to make it happen anyway. But mostly he figured it'd have to be something they both played by ear. He frowned at the idea of ribs being broken, and eyed up the way that Peter was holding at his waist. "Twelve," he said, because he wasn't really great at any kind of wet sciences, but Tony knew more than enough about the ribcage and sternum due to the arc reactor and lack of parts of his own to last a lifetime, frankly. "Do they just hurt a lot, or is it like -- a very bad sharp stabbing going to pass out pain when you move?"
