Nothing much happened on American Horror Story this week, except for an appearance by The Black Dahlia, a cameo by The Pope and the revelation that Vivien might be giving birth to the anti-Christ.

You know, just your basic episode of the FX drama.

It's unclear to which character the installment's title, "Spooky Little Girl," was even referring: Mena Suvari's version of real-life murder victim Elizabeth Short? The sort-of-reincarnated-and-totally-freaky Hayden? The fetus growing inside Vivien that may very well be "the essence of evil?"

I'll just go with all of the above, since each made quite the impression on viewers throughout the hour.

The seemingly random inclusion of The Black Dahlia as an actual player in this haunted house made more sense when you stopped to consider what she has in common with Hayden, Vivien, Tate and Constance; all characters who want what they can't have. In these respective cases, that would be: Ben, a happy marriage, a normal existence and a healthy family. And, for Short, fame.

Ironically, she ended up attaining this goal in death, something that could also be said for Hayden - in her warped mind, at least, as she believes she can manipulate her way back into Ben's arms - and also for Tate, who was clearly a troubled teen (school shooting and all), but who has managed to find love with Violet in the after-life.

We already knew that after-life could include sex between ghosts and humans, as Tate also proved with Violet... but, man, it was still disturbing to watch Hayden test this theory with Constance's clueless boy toy. It doesn't seem like much has changed with her, does it? That flashback to her and Ben's drunken night in Boston depicted the same sort of obsessive, scheming, direct young woman who now commits murder without thinking twice and who is now more dangerous than ever, considering she has no life left to lose.

Ben, conversely, is hopefully realizing exactly what he does stand to lose: his not-crazy wife. You're finally seeing things as they actually are. Well said, elderly Moira.

While this doctor's cold-hearted words to Vivien inside her padded room were obviously hypocritical - the guy cheated first, after all - they were also understandable in the heat of the moment. He's treated like absolute crap, only to find out that Vivien was having affair of her own the entire time?!? Combined with the fact that Ben is sort of a jerk overall anyway and the speech about not lifting a finger to help was true to his character.

But perhaps Ben is one figure who can get what he wants without dying first. He just has to make his way past his late, psychotic ex-lover and her band of ghostly friends. (The most troubling of which, by far, is Dr. Montgomery. His pleasure at draining and cutting up bodies gives me shivers just to think about.)

As for the closing reveal that Vivien might be carrying a "perversion of the immaculate conception," a demonic child that will destroy all the good in the world and end mankind as we know it... what can I say? That sucks. But it does drive home the lesson I've already preached:

Never have sex with a man in a rubber suit unless you are 100% sure of his identity. Remember that, kids.
