Okay. So I've got 6, including one who will have the most connection.
First is Corbin (corbin_ff), who hopefully you looked over when applying. Corbin....well, probably smokes cigarettes with Leicester. I doubt they'd call each other friends, but they might get along alright?
Next is JJ Higgs (jjunkie), Tanner's little sister. She's loud, rather unintelligent, emotionally immature, and generally all around fun. Um, she hates being alone and tends to pester just about anyone. She's a 5th year Gryffindor.
Next is Feiyi Moon (feiyi_moon) my 6th year Gryffindor. She's sweet as sugar and totally affectionate. She'll be nice unless he's ~real mean to her. She's Tori's (7th Slytherin) little sister.
Next is Cody Bexton, my 7th year Salem manager. I can't imagine they're going to get along.
Last is Toby Pucey (tpucey) my 7th year Ravenclaw that makes magical flowers. He's a nice guy, generally quiet, and his little brother is Gil, a 5th year Slytherin.
