13 Blink-and-You'll-Miss-Them Moments From the AHS: Apocalypse Trailer

The presence of the Rubber Man could only mean one thing: Apocalypse is set on the land that use to be home of the Murder House. Outpost 3 is clearly an entirely different building, but we don't need the same structure to encounter all the ghosts from season one. My guess is they built right on top of the remains of the Murder House, and that's why the Harmons, the Rubber Man, and all the other spirits are still around.
