So apparently Ryan Murphy told Lily Rabe (and every other witch) that she was going to be the next supreme. But then at some point he must have taken her aside and said, “Just kidding swamp bitch, you’re goin’ to HELL!!”
And we wonder why she’s not back for season 4.
I think that probably did something for them all as actresses though. Every girl on some level believed she was/could be the next Supreme. It’s one thing for the character to think that, but for the actress in the back of her mind to know (false or not) that she’s the next supreme it likely brought a subtle edge to her performance that would have been difficult to achieve otherwise.
