Re: YOUR CHARACTER'S TEAM?
Clem's a big supporter of the Sweetwater All-Stars, which absolutely everyone would know because she has a lot of All-Stars swag (both wearable and up in her room). I'm not going to fully open this can of worms, but she also has a favorite Quodpot team, which is the one her father played for and is local to Shreveport.
Reece is also a fan of Sleepy Hollow. His family's preferred sport is baseball, though, and they're Yankees fans.
Todd is a fan of Elysian Fields.
Ariadne, being British, is a fan of the Falmouth Falcons, but only nominally. She's never really followed the sport.
Ivy's family have always been big supporters of the Klamath Krakens, so the team's recent rise to prominence has been exciting for them. Ivy's not really a fan of the sport outside of school, but she'd probably say the Krakens, or maybe whatever her friends' favorite teams are (unless Laurel has a strong opinion, in which case her favorite team is whatever Laurel's favorite team is)
