I'm Grace and I've got this guy, Remus Lupin from the HP books universe. He's coming from about six months after the first war and has been a pretty sad pup. But he's adjusting, slowly but surely. He's a friendly fellow, generally polite. The only time he's a little edgy is a day or two leading into the full moon.
I've also got Bucky Barnes (MCU), who's coming from just before the battle in Wakanda during Infinity War. He's a grumpkins and kind of just old and tired and right now he's in a bit of a dark emotional space but he's trying to pull himself out of it slowly but surely. When he's not brooding he's actually a pretty fun guy with a great wit and sarcastic sense of humor.
Then there's Thor (MCU). He's coming from literally right when Thanos snapped his fingers after his whole 'you should've gone for the head' thing. So he's slowly sliding into the whole decline into PTSD situation we saw in End Game (I'm just trying to handle it differently than one long-running fat joke). While he's deflecting his depression and anxiety, he's usually trying to get people to have fun and make jest. He tends to like the Spiderlings. He won't be sure what to call this Peter, as he already has labeled Peter B as Peter the Elder and MCU Peter as Peter the Younger. But I'm sure he'll come up with something.
Last but not least, I have Gwen Stacy from Earth 65. She's got a sad history pattern with Peter Parkers dying in her arms for one reason or another so it's a little rough for her sometimes. She's not at the point in her life where she actually goes into his world and meets 616 Gwen yet but she knows that Gwen existed and that she died. She's spunky, definitely has the Spider-Wit and is usually pretty nice despite her kind of chip on her shoulder from her world where everyone thinks Spider-Woman is the worst.
