I think if Sasha were left alive she would actively doom herself over and over again. Oh sorry where’s Sasha? Well, while Jon was exploring the tunnels she already got Mike Crew’s location and has been hunting him for the past few days. Yeah, she doesn’t stop. She’s been cursed three different times. All different avatars. She’s been wearing a glass eye for the past week for unrelated reasons. I mean, it was clawed out by Michael, but that’s not important. Her and Jon have completely separate arcs that he doesn’t even realize she’s two seasons ahead. (“Sasha has been…. Missing for the past few days.”)
Sasha James who managed to avoid being First Girl, but she’s so committed to this mystery shit she’s not even trying to be Final Girl.
