AHS: Hotel celebrates Halloween tonight in episode 5, “Room Service.” Heading out into the night might turn out to be safer than checking into the Cortez.

Not ready to shake off the Halloween spirit just yet? AHS: Hotel episode 5, “Room Service,” extends the holiday. The ancient blood virus The Countess inflicts upon the chosen few demands to be fed with the blood of a thriving human being. What will a couple from the valley taste like? Our guess is probably kale with a hint of lemon. Iris is likely to find out when guest star Darren Criss checks in and tests the limits of her patience!

Recent convert Alexis Lowe will be reunited with her son Holden for eternity tonight as well. But will her new condition place her patients’ parents in jeopardy when she sees a way to save them from certain death? The Countess’ child army may be gaining a few new members by night’s end.

Meanwhile, John Lowe is coming undone. After a night dining with the nation’s finest serial killers, Lowe’s attention turns away from the Ten Commandment Killer and focuses on exposing the dark secrets of the Hotel Cortez. How can he prove to someone that in the 1930s the walls, chutes, nooks, and crannies were filled with the bodies of Mr. March’s victims without sounding insane?

A storm is brewing just outside the Hotel Cortez. Donovan, Ramona, and Iris are teaming up to take down the woman who ruined their lives — The Countess.

Watch AHS: Hotel episode 5, “Room Service,” tonight at 10:00 p.m. ET on FX.
