Friday works for me.
For relationships... Ellen is from Portland. She goes to college there, as well, for dance; working with the Fine Arts department sounds possible, so she may know Jess from campus, although she would stick more to the music/performing arts as opposed to painting and sculpture. But she is from an upper-middle-class background, so she may go to the art gallery occasionally; seeing Jess there sometimes wouldn't be out of the question, especially if they were in the same hiking club.
I notice they both have Attractive 2 as advantages; there might be a slight rivalry there, but it seems more likely that they would be at least casual friends.
For Romana; she hasn't been in America long, has she? Is it possible that she has been around to meet with the hiking club? They have at least that one excursion to the Cascades together, don't they?
Padrick wants to be an artist. Could they have run into each other occasionally in Jess's gallery, or do you just want to be friends from the hiking club?
Taran likes musical theater. Other than the hiking club, would he have hung out with dancers and performers?
I'm not really sure about Jack.
And, of course, I don't know Bran.
