ahahaha oh, Scottie boy. I hope he's learned his lesson about not letting it show when people get under his skin, because Pete's ten thousand times more obnoxious about that crap than Logan. And yes, he will flirt with Jean, because he will flirt with pretty much anything that has a pulse, and maybe a few things that don't.
Ooh, yes, I can see Callisto and Pete getting on marvelously. They can compare weapons and all the interesting ways they know to incapacitate someone with their thumbs. Fun!
If it helps Regan's mental crisis at all, Pete's really only teaching because he has nowhere else to go and he needs money. So...she's down with opportunism as motivation, right? :P
Hee, crazy Russian lady ftw! I'm not really sure how they'd interact either, but I think they could at least have an appreciation for each other's service to shady government practices.
Pete's thrilled to know he has the approval of a snot-nosed bratty rich kid. Really, he is. ;)
