There have only been three (named) people not attacked by a Red Devil: Cathy (who appears to be attacked in a promo), Grace (who I think is the bathtub baby, knows nothing), and Chanel #3 (who I think is head devil.) I think there are three Red Devils working together: Gigi (bathtub babysitter/shady lane hag), Boone (the one actually killing people cuz he has a permanent alibi, being “dead” and all), and Chanel #3 (head devil, bit of a sociopath, has access to KKT and info without being too suspicious, never been attacked). Chanel 3 is motivated by hatred of Chanel Prime and being “overshadowed” as well as being sociopathic and daughter of Manson. She got to Gigi by using Grace as bait. She told Gigi should could get her “daughter” back. She got Boone by giving him revenge on homophobic Kappa. Gigi thinks she’s in charge and wants Boone dead cuz he messed up with Zayday, but Chanel will want to keep him on since she can’t really kill people herself. She will personally kill Chanel Prime at some point, though.
