Fiona will call a truce with Marie Laveau to fight against someone threatening the witches in the next episode of "American Horror Story: Coven". As a witch hunter is roaming out there, Fiona looks for an alliance with the Voodoo Queen.

Hank looks tortured as Marie performs magic with a voodoo doll. Meanwhile, Zoe and Madison visit Luke at the hospital only to be scolded by his mother for bringing darkness into their house.

Also in "Head" that will air Wednesday, December 11 at 10 P.M. on FX, Cordelia's attacker is revealed and Nan learns a disturbing truth about Luke's past. The show will be on hiatus after airing the said episode and return in January. "Fringe" alum Lance Reddick has just been cast as Papa Legba, a "voodoo Satan," who will appear in the remaining four episodes.

Series creator Ryan Murphy tells EW.com that Fiona and her daughter Cordelia will "never be on good terms." He gushes, "That's one of my favorite relationships on the show. I think just when you think Cordelia has forgiven Fiona, something comes up, Fiona tries something else."

He goes on dishing, "Cordelia in the last four episodes in January finds out something even darker about her mother that turns things upside down. This isn't 'Gilmore Girls'. We don't have a mother daughter relationship that you love."
