'American Horror Story'

Sister Eunice has a word with monseigneur Timothy Howard. Meanwhile, Santa Claus is coming to town. (FX / December 6, 2012)

I would think that threatening an atheist with religious omens would be unsuccessful, but it rattles Arden enough to ask his arch-enemy Sister Jude for help in bringing down the corrupt nun.

"I don't believe in God," Arden says. "But I believe in evil. I've seen up close and personal."

Arden agrees to bring Mary Eunice to Sister Jude's room. But there's one problem. Dr. Arden is evil. He always has been and always will be. The error in judgment makes for a stunned Sister Jude when killer Santa walks through the door to her room.

"Guess what?" nutcase Santa asks Sister Jude rhetorically. "There is no God. But there is a Santa Claus."

As the crazed Santa pummels Sister Jude inside a locked room, Arden can't help but to be proud of himself.

"I trust my loyalty is no longer in question," he says to Mary Eunice.

Santa continues punishing Sister Jude, lashing her with a cane.

Earlier in the episode, Arden told Mary Eunice not to underestimate Sister Jude, but Arden himself does this by thinking Jude will be killed by a man who has been locked up so long, he probably couldn't see the sun through a telescope.

Sister Jude stabs Santa in the neck, ending the Christmas festivities.

Bloody Face reborn

Lana picks up at Briarcliff where she left off in Dr. Thredson's basement -- bed-ridden. That is, until she sees Kit drugged up and realizes the authorities are unaware of her situation and no one is coming to save her.

If she were Kit, Lana would probably smash a security guard over the head with a telephone to escape. Instead she uses a phone for its more conventional purpose and tries to call for help.

What Lana doesn't know is that Thredson is lurking in the shadows waiting for his opportunity to reclaim his victim.

"You made me kill Bloody Face," he says to her. "But like the phoenix, Bloody Face had to burn so he could be born again. Your skin will be the start of a whole new Bloody Face."

Thredson grabs Lana and begins his intimidation routine, but the doctor is a lot of talk. His lecture gives Kit enough time to reach the scene and knock Thredson unconscious.

Lana wants Thredson dead, but Kit needs the doctor to corroborate his story and prove his innocence in the murder of Alma and the other girls. Instead, Kit and Lana tie Thredson up and leave him in one of Birarcliff's abandoned rooms.

"One day I'll bury you," Lana says.

Final thoughts

The devil displays a good sense of humor as Mary Eunice. When she's not killing people, Mary Eunice is usually messing with their minds. In this episode, she used Christmas as another opportunity to have some fun. With Sister Jude no longer in charge, Sister Mary Eunice decided to celebrate her own way.

"That mean old Grinch tossed out all our ornaments, so we need to improvise," she tells the patients.
