I’ve seen the raws and short explanation about the possession

Short explanation if you’re still confused about the whole Tori and Troy sharing the same body concept and if Toris alive. Basically, Troy spirit currently has control over Tori’s body however her spirit is still alive, just that her consciousness is in a sleep like state. Think of it as, when two souls in the same body but the stronger soul will end up dominating the body forcing the other one to be dormant. That’s what’s happened here, but rest assured, she’s still there, in the subconscious, alive
