“American Horror Story” fans might want to grab a pillow to hide behind when episode 9 of “Freak Show” airs on Wednesday. The FX miniseries has had its spooks and scares throughout Season 4, but the upcoming episode is said to be one of the most chilling yet.

As we previously reported, episode 9, titled “Tupperware Party Massacre,” will find Jimmy (Evan Peters) sinking into “drunken despair” while Stanley (Denis O’Hare) and Elsa (Jessica Lange) “track down” Bette and Dot (Sarah Paulson). The twins are guaranteed to be in grave danger with the con man and jealous freak show leader on their tail. But viewers have bigger things to worry about -- Dandy (Finn Wittrock).

Episode 8 of “American Horror Story: Freak Show” concluded with the twisted boy murdering his own mother, Gloria (Frances Conroy). Despite how protective and dedicated she was to her son, Dandy decided to put a bullet through her head, and then proceeded to soak in a bathtub full of her blood.

Murder is nothing new to Dandy. On top of being responsible for killing Dora (Patti LaBelle) and Andy (Matt Bomer), viewers discovered he has a dark history of bad behavior and malicious acts. However, no one anticipated him turning violent on his mother. With the shocking twist behind us, fans are now wondering who's next on Dandy’s list?

Wittrock says his character doesn't plan to slow down.

“I’ll just tell you that the next one, I think his body count might double,” the actor dished to E! Online while promoting his upcoming movie, Angelina Jolie's “Unbroken.” “The next one really, honestly takes the cake. Even I’m scared.”

The synopsis for episode 9 only states that “a reading from Maggie (Emma Roberts) spurs Dandy to action.” It’s unclear what “action” the plot description is referring to, but one theory has to do with Maggie’s connection to Stanley. The pair started off as partners looking to make a quick buck off of dead freaks. However, Maggie has grown fond of the people living at the camp. She refused to kill Ma Petite (Jyoti Amge) and has been urging Jimmy to leave the camp. Could she possibly set up Dandy to kill Stanley? A way to eliminate Stanley as a threat would be to reveal his intentions for Bette and Dot to Dandy.

“American Horror Story” fans will have to wait and see what happens, but the promo video for “Tupperware Party Massacre” does tease some terrifying scenes. The video shows Dandy charming his way into a woman’s home (potentially during a Tupperware party) under the pretense of borrowing her telephone, but the next scene shows a handful of women floating face down in a pool. Meanwhile, Dora’s daughter Regina (Gabourey Sidibe) needs to watch her back. The girl is bent on finding out what happened to her mother -- and it looks like Dandy is ready to tell her the truth.

“American Horror Story” Season 4, episode 9 will air on FX on Wednesday, Dec. 10, at 10 p.m. EST.
