Since we know that IM:AA is getting a second season, I thought I might as well make a topic for things we'd like to see in Season 2.
For me, I've got a character I want to see make an appearance: Natalia Romanova, A.K.A. the Black Widow. Obviously, she'd be working for Nick Fury, though I think in this incarnation she should appear as a teenager at around a similar age to Tony Stark. It'd add an interesting, possibly comedic depiction of Black Widow maybe trying to charm Tony, only to make life hell for him later on.
Anything else you want to see in future episodes?
