As much as Tony's become a father figure to him, he's not sure he'd ever be able to get to the point where he could call him Dad. It was embarrassing for him, and even though Tony said it'd be okay, wouldn't it be embarrassing for him, too?

Peter's sure Tony would get just as ribbed for it as he would. Probably more.

"I'll try not to disappoint you, either."
