Everyone’s favorite “American Horror Story: Hotel” characters survived another night at Hotel Cortez – but can they make it through another Halloween celebration? With “Devil’s Night” out of the way, the tricks and treats continue with episode 5, “Room Service.”

The synopsis for Season 5, episode 5 teases that Alex (Chloë Sevigny) will get back to work after taking Countess Elizabeth (Lady Gaga) up on her offer to spend eternity with her son, Holden (Lyric Lennon). Alex is now infected with the ancient blood virus and has the “thirst.” But that doesn’t mean she’s going to quit her job as a pediatrician.

The promo video for “Room Service” shows the noticeably paler doctor visiting with her measles patient at the hospital. His health is continuing to down spiral and his anti-vaccination mother is fearing the worst.

“They asked me to sign a DNR,” she tell Alex, frantic at the thought. “Please tell me that we’re not there yet.”

But Alex can barely focus on her patient because she’s too busy eyeing the pulsing vein on the mother’s neck.

“I’ll figure it out,” Alex says weakly.

But can Alex save the little boy? The synopsis adds that she’ll use an “odd treatment” on him. Fingers crossed she doesn’t try to experiment with her deadly new blood.

Meanwhile, Alex’s husband, John (Wes Bentley) is ready to rip Hotel Cortez apart after his Devil’s Night Soiree with James March (Evan Peters). Although Sally (Sarah Paulson) tried to convince him that he was drunk and hallucinating, it appears as if John knows what he saw. However, that doesn’t mean that he’s “well.” The detective looks almost crazed, demanding that his task force “strip those walls down to the studs” if need be.

Finally, “American horror Story” viewers will catch back up with Iris (Kathy Bates), who died in episode 3 and was brought back to life with the ancient blood virus by her estranged son, Donovan (Matt Bomer). The synopsis reveals that she’ll be “tested by a couple that hates Halloween.” But the promo video hints that she might have bigger problems than that.

Donovan takes his mother to Ramona Royale (Angela Bassett), who warns him that he’s “reckless.” We know that The Countess doesn’t like her “creations” using their blood to sire others – so does that mean that Iris’ life is in danger? Either way it sounds like the trio has a plan to take down the Hotel Cortez owner.

“American Horror Story: Hotel” episode 5 airs on Wednesday, Nov. 4 at 10 p.m. EDT. Watch the promo video for Season 5, episode 5 below:
