Oh Loren will DEFINITELY try to make Lina rue the day if she punches him, his face is VERY IMPORTANT. Nevermind that he's a shapeshifter and he can fix that real fast, it's the principle. Nick and Frankie would probably get along really well, plus comics!Bucky and Wolverine know each other so obviously they have to get a drink sometime. And Nick will appreciate Quinn's contribution once he actually loses that arm. And also the chance to talk shop with Rana.
I MEAN if you want to set Cady up with having to deal with Loren... they'd never be friends but he would definitely be resentful of her success which is equally fun.
Nick'll pass on the werewolf. Loren would consider it. That Fenrir thing worked for mythology!him.
