Oh god. Why do I see this group ending up a fucking riot? And Cole trying to get them all high on top of that and Billie is just sitting there, "Don't mind Cole, she's our hippie"
"No sis, got it twisted. Good vibes roll better than bad, and he best vibes really high vibes." Cole will laugh a bit 

Oh god. Clary might just scare him at first with how hyper she gets. Because, you know, she loves new people.

She'll be all like. "Hi! I know you! Um.. umm... umm... fuck! Shit!" She'll be trying to think of his name. She'll shake her head a minute before looking at Logan and asking. "I know him. Why do I know him but not his name?" 

Ha ha. Poor guy doesn't know what he's getting into.
