And now for something happier.
Su (the purple haired girl in the middle) is a character who's probably from a different 'universe' than Tori and Iris.
Or at least a different town.
Maybe?
But she's the kind of person who will befriend ANYone/thing, without question, and doesn't need much of a reason to like someone beyond 'they do nice things'. Her best friend is the monster who lives under her bed. And she's friends with the ghost in her crawlspace.
So if they ever were together, Su would be like "let's go climb some trees and pretend we're howler monkeys."
