Warning! This article features spoilers from AHS: Hotel episode 8. Read at your own risk!

American Horror Story: Hotel returned FX last night after a short hiatus, giving us the biggest reveal yet.

Titled "Ten Commandments," the episode went into great detail to explain the killer Detective John Lowe (Wes Bentley) has been hunting down. We were shocked to find that Lowe has actually been coming to Hotel Cortez for five years. But as Sally (Sarah Paulson) explained, the hotel is a jealous mistress, it's possessive so it never lets you take anything with it. This is why Lowe had no memories about his double life up until now.

We finally got to see just how infectious James March (Evan Peters) can be, as Lowe just needed a little budge to reach the darkest place in his heart. We also found out the real reason why The Countess (Lady Gaga) took Holden.

While this episode finally gave us answers we've been burning for, that doesn't mean there won't be any more plot twists during the rest of the season.

In next week's episode titled "She Wants Revenge," it appears like just about everyone associated with Hotel Cortez is on a mission to take down Countess Elizabeth.

No one wants revenge on the Countess more then Ramona Royale (Angela Bassett), and it seems she will stop at nothing to make sure this happens. Ramona and Donovan (Matt Bomer) must figure out a plan to finally put an end to the queen of the castle's reign before she marries Will Drake (Cheyenne Jackson).

Between her enemies plot to get rid of her, and even the housekeeper advising Drake not to go through with the marriage, it may turn out that The Countess' wedding doesn't go as planned.

Here's how FX describes the episode:

The Countess is reunited with her one true love. Donovan and Ramona take another stab at revenge. A careless decision lands Alex in hot water.

Directed by Michael Uppendah and written by Brad Falchuk, "She Wants Revenge" airs Wednesday, Dec. 9 at 10 p.m. ET on FX. Check out the promo in the clip below.
