That's the only thing I'll accept. Succubus is really the only logical thing given that she's always having sex this season, has a nefarious plan (most likely collecting souls for her real bae Satan) and even attracts the women.
Ryan said there would never be vampires or werewolves, so if he lied to me and makes my fave that...
What if Gaga's a succubus and she's collecting souls for Tate's kid, who because he's like half ghost is aging super fast? There's another connection to Murder House.
