His smile turns a bit goofy when Pepper gives him that look -- it's one he knows well, but it never fails to melt his heart on contact. It takes him a second to refocus on Steve, but he's just as concerned with the other man tonight, if not more. There's a lot riding on this night.

"And we don't usually have guests. At least... ones with manners." Cough Harry Osbourne cough :) Tony makes a dismissive noise at the suggestion of Steve lifting a finger to help, how dare tbh. "Guest means you relax and we do all the hard stuff. You already made cookies." He won't hear an argument on this!!!
