Haha, yes, I definitely read over Corbin and Tanner and Scorpius and...well, I always read at least some about everyone before I join a rpg because I want to have a handle on all of the characters. I didn't read everyone in detail but I picked up a lot of it and as I'm responding to SLs I'm reading more. I'm kind of anal about that, haha.
Smoking buddies it is, then! I can see them getting along okay -- it helps to have the cigarettes thing in common, but I also agree that they probably wouldn't be the greatest friends, or very close at all -- possibly with the potential of not getting along if they got much closer because they're similar in some ways that might clash. But in that distant, better than acquaintances since they're dormmates but not really any closer than that kind of way, I think they would get along fine.
I don't know how much Leicester would interact with JJ. I guess depending on how it goes, he could either enjoy interacting with her or prefer to not interact with her. >.> She's one of the hardest to say about so far, because Leicester is inclined to not be interested in people who are loud and unintelligent like that, but he might actually enjoy interacting with her. Hard to say. :)
Aww, Feiyi's adorable! I don't think Leicester would probably interact much with her, either. I don't think he would personally get the housewife goals, but he's of the opinion that everyone should do what they want with their lives, so he wouldn't have a problem with it.
Haha, I see what you mean about Cody and Leicester. They'll probably either ignore each other or clash horribly.
Toby sounds really cute (and I adore his PB). I'm not sure how much he would have interacted with Leicester before, but I don't think they would have gotten along horribly have or would get along horribly if they do. He would find the flowers thing interesting, just because it's sort of an unusual thing, and Leicester appreciates when people are different like that.
And I'm not really sure how much Fred and Leicester would have interacted either, being in different houses and different years, but I don't think there would be any conflicts, but maybe also not much interest, since they seem to be very different types of people.
