Aleks Rasputin: Kitty and Storm are close so figure their children are too? Al is like 2-3 years older but they both also have a knack for languages, probably hung out as kids? Tried babbling at each other in whatever new stuff they picked up? Maybe Kitty visited Wakanda a few times while the family was there and Al came with her. Xkid friends! He's been gone a few years but is back now and they can always reconnect and catch up.
Cara Drew: Probably haven't really met, though they could through her bro Cal. They have the same focused work ethic in common though so that's good. Other than that...she's his teammate's lil sis is all XD
Cliff Bishop: He's a teenager and boring. Booo. Nothing from him.
Peggy Rogers: Yay close in age! I think they're pretty similar in that they're both tough, independent, take on a lot by themselves, and have high expectations of themselves. So I think they could get along just by those things. Peggy is obviously more outgoing and social (and bothersome! :D), but probably would have a respect for Ainet since she sees her as having a similar work ethic. Also flying buddies? Flying buddies? Yes?
