Hello! I'm Paige and I've got too big a cast to list off, but you can check the full list out in the Contact list thingy. My big ones that would interact with yours are my MCU folks:
Pepper Potts - will mostly frowny face and try to reign in Tony's more destructive pokes. She has a stabilized Extremist inside her, so she might get flame-y around him.
Natasha Romanoff - kinda doesn't give a shit about Loki until he starts causing trouble. She does feel like he owes her for what he did to Clint, but since her Clint isn't in game, she's probably just going to watch Loki from afar.
Jane Foster - she'll be surprised to see him alive, for sure. She thinks he's kind of a dick, but since he "died" helping her, she's inclined to give him a second chance and make an effort to be nice to him.
Steve Rogers - he will turn on his Captain America voice and warn Loki that he isn't to cause trouble in Test City, and if he does, the Avengers will be there to stop him.
Mostly, only Jane likes him lmao. Oh well! The rest of mine are either badasses or supremely innocent and Disney Princess-like.
I'm up for whatever, and you can reach me at any of my peeps' drop boxes! Welcome!
