“American Horror Story” season six could probably have two themes in one season.

The upcoming sixth installment of the FX hit series is expected to explore two themes within one season after creator Ryan Murphy announced that he has two ideas in mind for season 6, TV Line reported.

“The interesting thing about this season is we’ve been working on two ideas at once, which we’ve never done. So I don’t want to say what it maybe is,” Murphy announced at the recent PaleyFest. “Both things that we’re writing right now – we haven’t declared a winner – will have a different form, so we’re excited about that. We’ll talk about it soon, but we haven’t landed on it yet,” he added.

iDigitalTimes has suggested that the two themes in season 6 could be achieved by introducing travel, reincarnation, or multiple personalities.

Murphy earlier hinted that the sixth season of AHS will have something to do with children. However, he did not mention if the kids will play scary characters. “If you look at horror tropes, the innocence of children, that sort of wide-eyed entryway into some world is always very dramatic and satisfying,” Murphy teased.

So far, the actors that were confirmed to make an appearance in season six are Lady Gaga, Angela Bassett, Denis O’Hare, and Evan Peters. However, these stars have been keeping details of the roles that they will play in the upcoming season under wrap, iDigitalTimes wrote.

Murphy earlier said Kathy Bates, Sarah Paulson, Matt Bomer, Wes Bentley, Cheyenne Jackson, and Finn Wittrock have been invited to return in season six. Wittrock, on the other hand, told The Wrap that many of the previous “American Horror Story” characters may not return this season. “I have heard it is going to be a little tighter — there were so many story lines in the last one and it was so big and epic, I have a feeling it might be a little more claustrophobic. A smaller cast,” he said.

The “American Horror Story” season 6 filming will most likely begin this summer. It is expected to premiere on FX in October 2016.
