Nightmare Fuel: American Horror Story: Coven
Madame LaLaurie's attic where she tortures and imprisons her slaves
One slave had his eyes and mouth sewn shut, and it was heavily implied that she forced feces into his mouth before having it sewn shut.
Another slave had the skin of his face removed.
Even worse: LaLaurie is based on a real person. Her French Quarter mansion is said to be the most haunted house in New Orleans.
The consequences of having sex with Zoe.
Madison's explicit gang rape by the frat boys. The scene is horrifically detailed, and is regarded as a horrifying scene.
It's far more intense than the Lana rape scene in Asylum, to make matters worse.
LaLaurie forces a slave to wear a dead bull's head over his face. Just think about how disgusting that would be.
LaLaurie's fate. Many would say that it was rather karmic and well-deserved, but it's still incredibly unsettling. It's a wonder she didn't go insane. That could also be chalked up to the immortality potion, which is kind of worse in a way.
"The Perfect Boyfriend" when it awakens. Evan Peters' complete rage is far scarier than anything achieved in any of the seasons so far, and it lasts only a few seconds.
While his rage doesn't last long, he seems disoriented, almost feral, and only grunts and whimpers. So far, there is no sign of the nice young man Kyle used to be.
And it gets worse in "The Replacements", the following episode. FrankenKyle kills his mother in a fit of rage to the point of caving her face in with a statue. Granted his mother was incestuous with him...
Kyle's mother is unhealthily obsessed with her son. After her son gets back home barely able to walk or speak, what does she do? She rips his shirt off, feels him up, and starts kissing him. Which implicitly triggered FrankenKyle's memories of the OTHER times she did things like that, so we really can't blame him for going nuts and bashing her face in.
Fearful Pranks Ensue has a lovely scene where a living Minotaur head is mailed to Marie's hair salon.
FrankenKyle smashing his head into the bathtub in a catatonic state, covered in blood.
Spalding took Madison's body after she was killed by Fiona and is using it as a doll. Let us hope dressing her up is the only thing he does with her...
Joan's parental discipline techniques, but especially the bleach enema. Poor Luke.
The cold steely fury on Hank's face as he shoots up Cornrow City
Though it's played for comedy, the method Myrtle uses to procure Cordelia's new eyes is still frightening, as she cuts out one eye each from Quentin and Cecily while they're paralyzed, then dismembers their bodies and dissolves them in acid.
Cordelia stabbing out her eyes with garden shears is not fun to watch.
LaLaurie and Marie's ultimate fates: Marie has to spend her afterlife torturing Bourquita, something that even she doesn't relish, and LaLaurie is forced to watch.
According to the latest episode Hell is different for everybody, but the same in the sense that they are eternally stuck in the worst time of their lives with minor changes from their situations from when they were living. During her brief time there Queenie had a never ending work day at the restaurant she worked at before she went to the academy.
Probably is some kind of Fridge Horror but Kyle strangling Madison to death even though in the beginning of the season he was the only member of his fraternity who tried to actually stop his frat brothers when he caught them gang-raping Madison.
Don't tell me you didn't shit a brick when Marie did that white-eye-tongue-wagglin' thing and caused the two cops to fatally shoot each other. What a crazy/creepy display of power. Here's a nice reminder.
