Yesterday, American Horror Story: Coven fans watched the FX show's bewitching finale. Cordelia actress Sarah Paulson is revealing what the finale means to her and what is next for season four of American Horror Story.

WARNING: This article contains spoilers from the finale of American Horror Story: Coven.

Paulson said she was surprised when creator Ryan Murphy told her that Cordelia was the Supreme. She had her bets on Queenie.

"I had to pull the car over," she told The Hollywood Reporter. "I was so surprised. 'What do you mean I have to burn Myrtle (Frances Conroy) at the stake?' I was less interested in my being the Supreme and more concerned that I had to burn her at the stake."

Paulson was satisfied with the season finale.

"I was most pleased with how it ended up between me and Fiona," she told E! News. "...Of all the scenes done this season to be proud of ... the thing I'm most proud of is my scene with Jessica [Lange] in the finale."

Lange has stated that season four of American Horror Story will be her last. Paulson is hoping that this isn't case.

"I can't imagine doing American Horror Story without her," she told E!. "I do think Jessica Lange and American Horror Story are synonymous with one another, and I do think she makes it something really extraordinary, no question. I can't imagine her not doing it, but at the same time, if they feel the show must go on, the show must go on ... Maybe everyone will just have so much fun next year that she won't be able to say goodbye."

Paulson, on the other hand, says she will definitely return for the next chapter of the shocking series.

"I'm on track, and that is the plan," she told THR. "Last year, [Murphy] announced [the season theme] at PaleyFest, so he might do that again...I know what he has in mind for me, and I hope it happens because it would be one of the more exciting things that I've gotten to do."

The Supreme promises that her next role will be just as supreme as Cordelia and Lana, her American Horror Story: Asylum character.

"I know it will not disappoint and it will be, for my money, one of the more exciting themes," she told THR.
