When (Kathy Bates) (Iris) brings the food to the young couple in their room, you can see on the TV a brief scene of Suspiria (1977), one of Dario Argento's most popular movies.
Darren Criss guest stars as Justin, the obnoxious guest giving Iris (Kathy Bates) a hard time. He previously starred in Ryan Murphy's Glee (2009), as Blaine Anderson, where Matt Bomer guest starred as Blaine's older brother.
The kids represent the characters of Peter Pan. The boy as Captain Hook, Madeline as Wendy, the boy in the green lizard suit as Peter. They will be forever young. Later the boy as Peter is positioned next to Madeline as Wendy, with the evil boy as Captain Hook standing behind them. There is also a boy in a wolf mask as one of the lost boys, a girl with fairy wings as Tinkerbell, and the secretary dressed as Tiger Lilly. And another boy has a feather in his headband as one of the Indians.
Matt Bomer's character, Donovan, calls Angela Bassett's butler, "Jeeves," as Madison Montgomery (Emma Roberts) did to the Coven's butler, Spalding (Denis O'Hare), in Season 3.
