Well, that was gross. This week's episode of American Horror Story finally wraps up a main storyline, but it also contains the most vile thing I've ever seen on TV. We learn all about what drives modern-day Bloody Face to his murderous ways, but not before a nauseating (and more than a little traumatizing) scene with a pneumatic prostitute who . . . nurses him. Yes, it tops the list of things I can't unsee, but I won't cry over spilled milk.

Now that Sister Mary Eunice and Dr. Arden have met their fate, there's room to focus on the alien subplot. It seems that it's not so much their existence that matters as it is the baby they plant inside of Grace . . . and Alma? Let's break down the most insane moments of this week's episode when you read more.

A lot has happened in the aftermath of last week's holiday-themed episode, with the most significant change being Sister Jude's major demotion. She wakes up shackled and restrained in a cell as a Briarcliff patient, in one of those "this is my worst nightmare realized" kind of scenes. Too bad for her, it's reality. You could call it karma, but I call it a setup. While things may be looking grim for Sister Jude, Lana and Kit get their first real chance at escaping Briarcliff, Bloody Face, and the electric chair.

But a silver lining is never what it seems on American Horror Story, and the gruesomeness doesn't let up this week, either. At least we get an explanation for the aliens (finally!), and it could be connected to that other seemingly rogue story line: Dr. Arden's Nazi experiments. Let's break down the most insane moments after the jump.

It's beginning to look a lot like Christmas at Briarcliff in the latest episode of American Horror Story. Instead of tinsel and ornaments, however, the asylum tree is strewn with dentures and hair bows with the hair still attached. And Santa? After the last two episodes introduced the little serial killer girl and the angel of death, "Unholy Night" gives us our newest creepy character, a family-murdering Saint Nick (played by a darkly magnetic Ian McShane) who ends up locked in a room with Sister Jude and a closet full of whips.

Whatever has been simmering inside Sister Mary Eunice finally boils over, and she gets even more blood on her hands. Dr. Arden seems to struggle with her lost innocence, and for the first time ever, we see him and Sister Jude working as an odd-couple team. But it wouldn't be an episode of American Horror Story without some jaw-dropping surprises. Let's break down the most insane moments after the jump.
