-We know it's a girl.
-It probably isn't the Chanels since chronologically, they were still at the house while Boone was being murdered.
-We know that the 3 murderers planned one faked death, so even some of the dead characters can't be ruled out.
Here's a list of characters who the final Red Devil absolutely can't be:
- All male characters (except maybe Pete if he had a gender reassignment surgery at some point)
- Zayday (Boone was in love with her)
- Dean Munsch, Denise Williams (Adult women, not related to the baby)
Here's a list of who probably aren't the Red Devil:
- Grace (It's likely her Dad isn't lying about her past, and that her police records weren't faked)
- Chanels 1, 3, 5, 6 (They were in the middle of a fight while Boone was getting slaughtered)
Here's my prime list of suspects though, the only people who could be the Red Devil in my eyes:
1. Chanel #2: If Boone faked his death, it stands to reason that his partner may have as well. Also, her parents didn't care at all about her death, which may point to her only recently being adopted instead of someone who grew up with them. Also, her "fever dream" appearance would make a lot more sense. The biggest knock against her though, was her death being on screen so...
2. Chanel #3: She's just creepy. She claims her father is Charles Manson which just sounds like bull shit, she wanted to be Alibuddies with Predatory Lez, and people tend to die when they see her ears apparently. I'm guessing she may have a split personality that emerges whenever she takes off those muffs, which would explain why when she saw Boone she was surprised. Of course, timeline wise, it'd be awkward explaining how she got dressed as the Red Devil, killed Boone, slipped back to the house, and then witnessed Chanel killing Hester so quickly.
3. Pete: No alibi for anything substantial, established creep from episode 1, could have had gender reassignment surgery at some point to explain why he isn't a girl. Shocking, but not all the likely in my eyes.
4. Grace: Besides maybe Chanel #2, she was the only plausible girl that was totally unaccounted for at the time of Boone's death. That's all there is to this possibility though, there's way too much other stuff contradicting this.
Yup. I thought about this way more than I should, but to my credit I called Gigi as the mastermind back in episode 1.
