“American Horror Story” fans better get ready – because a war is brewing within the Coven. While the Salem witches definitely have problems with Marie Laveau right now, they’re putting the Voodoo Queen on the backburner to deal with a more deadly issue … Supreme witch Fiona.

For those that haven’t been following, Fiona’s health is failing. Desperate to stay the Supreme witch forever, she murdered Madison and has been plotting ways to stay young and powerful.

Unfortunately for Fiona, Madison is back from the dead, and Cordelia and the other Miss Robichaux witches are onto her deadly plans … and have hatched an equally lethal scheme of their own.

The drama will begin to unfold in episode 8, and “American Horror Story” fans are in luck because they can watch a sneak peek video before “The Sacred Taking” airs at 10 p.m. on Wednesday, Dec. 4.

In the clip leaked by SpoilerTV, Nan discovers that Luke’s mother, Joan, is punishing him next door for his involvement with the girls at Miss Robichaux’s. However Nan can’t rescue Luke because Cordelia is laying down the law with her pupils.

“Sit down, Nan,” Cordelia warns her. “Let go of everything outside this room right now.”

Long gone is the warm and innocent headmistress. Cordelia is now bent on making sure that no one destroys the Coven.

“Losing Queenie is a terrible failure … my failure,” the headmistress continues. “But as of now she’s dead to me. And no one else will slip through the cracks.”

Beginning to map out their battle plan for Fiona, Zoe warns that they need to kill her immediately. However Madison demands that she get the honor of slitting the Supreme’s throat.

“No,” Cordelia tells the witch. “You have to stay hidden until it’s time. She cannot know your back. We have one shot, that’s it.”

But their meeting is interrupted by the doorbell, and when no one answers (due to the unfortunate absences of Spalding and Madame LaLaurie), it’s up to Zoe to see who is paying the witches a visit.

And that’s not all that “American Horror Story” fans can look forward to. According to TV Line, episode 8 will also find Kyle’s speech improving. While that sounds like a step forward for Franken-Kyle, TV Line teases that “Madison isn’t exactly thrilled with what he says.”

“American Horror Story: Coven” episode 8 airs on FX on Wednesday, Dec. 4, at 10 p.m. What do you think will happen? Let us know in the comments section or send me a tweet at @AmandaTVScoop.
