I was looking for something new to do with Tony, and thought taking him from an earlier point in his canon might be interesting. To see in what ways his character grows when he doesn't get that kick in the pants from Fury and find himself joining the Super Secret Boyband anyway. So it's kind of like IM3 where he has to rely on himself, but then there are also other people from other fandoms that could probably help him if he can just get out of his own head enough to realize being part of a team isn't the worst thing in the world.
Ron is definitely down for that. The first person he met when he arrived in the game was Julia, and they did a kind of magical show and tell. So he's super interested in the other kinds of magic.
