"Oh, Whew. Lucky me." Despite how it's a joke, it's kind of not, too. Being thrown around the room has nothing on this, even if he'd actually let B do it, too.

This is pretty good.

He doesn't exactly lead, but he does sort of try to at least show he's into it by nudging B this way or that, when it seems appropriate. Mostly just circling in place - just to prove they're dancing.
