She'd honestly probably really like Jack, with or without the gossip (though she loves good gossip) - and she'd find how he uses his magic fascinating. Since hers operates such a specific way, I think learning about how his works would delight her.
Aw, but Theo just wants to be friendly! (And is full of bs anyway. But she won't press.)
I think as long as Eva doesn't lump her in with humans, they might actually get along pretty well? I can see them not sharing the same tastes though, but in like a fun way rather than an argumentative way. She'd probably end up making a deal with Eva that if Eva picks out her dress, she gets to pick out Eva's.
And yay! A card partner! And he probably would? Anyone who can follow that her powers can't really...replace psychic ability could figure it out real quick, and she's not super shy about it either, as long as its after hours. She doesn't actively and awfully cheat anyone at the carnival (except little things for shits and giggles), but customers are free game, you know? I think she'd find him really interesting!
