ALSO! THEORY:
Since only 7 people can be in purrgatory at one time, I feel like that might mean every character represents a deadly sin? Idk tho.
sean: lust (bcuz hes always talking about sex)
oliver: pride (kinda obvious, when he talks about never liking being wrong when u are doing his arc)
kyugsoon: gluttony (bcuz she eats stuff)
natalie: sloth (only because she mentioned being lazy and not liking exercise)
idk on the others :p maybe elijah is envy but idk. will update.
