lily + ethan.
Let's see, I think Betsy Braddock has been here the longest. She's the most settled in, but she also might have the most patients attached to her already. And she's psychic, so whether or not you're comfortable with that is also a thing.
Major Lilywhite (his actual first name) has also been here a long time. No psychic powers on that one.
I don't know Rachel Summers or Charles Xavier very well, but I know they're both psychic, and that Charles disappeared for a while and came back recently. I've heard they're good people.
Phoebe Halliwell I believe is a witch? Not the kind of witch I am, though, different universe. She's been quieter on the network, so I'm not really familiar with her, but she seems nice.
