Eenie, meenie, miney, moe, which "American Horror Story" theme will make it on the show?

The location of the upcoming installment of FX's anthology series is still up in the air, but executive producer Ryan Murphy made sure to tease audiences about potential story ideas at a PaleyFest panel on Sunday.

"The interesting thing about this season is we’ve been working on two ideas at once, which we’ve never done," Murphy explained at the closing night panel of the annual TV celebration, according to Entertainment Weekly.

The prolific producer, however, did let it slip that the two themes in the running both include children. The previous season featured a considerable amount of child actors, who played the vampire children of Lady Gaga's character, The Countess. Perhaps we'll see those blond bloodsuckers again when Season 6 rolls around.

"The show has always felt to me like an opera," he continued. "Both things that we’re writing right now, we haven’t yet declared the winner, will have a different form than we’ve ever done, so we’re excited about that. We’ll talk about it soon, but we haven’t landed on it."

A few months ago, rumors swirled that Season 6 would take a stab at the Slender Man, a supernatural character who psychologically traumatizes his victims, often children. But the theory was quickly dispelled with a source close to the series reminding fans that they'll have to wait until March to find out the theme of the new season.

Us right now:

To satiate the fan's desires for Season 6 scoop, Murphy did reveal that all the actors on the PaleyFest panel, including Sarah Paulson, Kathy Bates, Denis O’Hare, Angela Bassett, Matt Bomer, Wes Bentley, Cheyenne Jackson and Finn Wittrock, are set to check back in.

"I don’t want to say what it is, but I will tell you that every darling person up here that wants to come back can come back," Murphy told the audience.

One thing we can confirm about the upcoming season is the return of Lady Gaga. After garnering critical acclaim and a shiny new Golden Globe trophy, it's no surprise that the pop star would be open to exploring a new horror story.

Although she was absent at the panel, Gaga's co-stars were quick to sing her praises, with Bomer describing her as "incredibly courageous."

“She reminded me of Jessica [Lange]," Paulson added. "She was one of the most emotionally available actresses I’ve worked with."

As the series progresses, Murphy also promised that the strands connecting the five previous seasons will become more clear, referencing Paulson's dual appearance in Season 5 as Billie Dean Howard of "Murder House" and Sally McKenna from "Hotel."

"The deeper that we go into the series -- hopefully we’ll last decades and decades -- you will see that there’s a definite universe and all the worlds are collided, sometimes in a very bizarre, interesting way," Murphy said. "You will be seeing more and more of that as we go along."
