Steve and Tony's mutual fanboying throughout the oral history is super-adorable! Tony, in particular, manages to sneak in a mention of Steve's awesomeness no matter what the conversation is about. There was a great bit in one of the recent chapters where they're being interviewed about Black Panther, and Tony says lots of complimentary things about Panther, and then he's all "Hey, you know who else is awesome? Captain America!" It's just too cute.
