Mental notes taken while watching the third episode of American Horror Story: Hotel: Check your mattresses extra carefully before getting into bed, and don’t even think about haunting Sally’s hallways.The death count — and undead count — grew even higher this week, plus we saw the arrival of Angela Bassett (we’ll get to that in a bit) and even a Ponzi scheme, for good measure.The episode opens with Tristan strutting around the hotel like he owns the joint, and making nice with Evan Peters’ ghostly James Patrick March. “I know everything about you,” he tells him (How? Google, of course). Flattered by the psychotic praise, March encourages him to put all the Cortez’s secret murder hallways to good use (there’s a glimpse of a “Black Closet” I would not be surprised if we visit again at some point this season, if only in my nightmares). But they’re interrupted by Will Drake and his fashion editor pal Claudia, who marvel at Tristan’s new youthfulness and the lack of scar on his face before turning their attention to how they want to renovate the hotel. Tristan tells March and Miss Evers not to worry, because he’s going to take care of it.
