If you looked at the realtor on this week's American Horror Story: Hotel [1] premiere and thought she looked familiar, it's because she's already been on the show. We actually already knew that Christine Estabrook would reprise her role as Marcy [2], but we didn't anticipate that she would make a fantastically subtle reference to her time on the first season. One of her first lines on Hotel is: "I had to put my dog down. He came to me through very unfortunate circumstances." It's easy to glaze over this line, but wait! Marcy is referring to Hallie [3], the Harmon's dog!

If you recall, she adopts the dog after — spoiler alert — the Harmons all die in the Murder House. When the Ramos family comes to check out the now-vacant home, Marcy tells them a sugar-coated version of what has happened in the house. She's holding Hallie, who she calls "the only remaining member of the Harmon family." Spooky!
