The Piggy Man (Marti Matulis) from this season is connected back to Season 1 in murder house. Derek (Eric Stonestreet), an insomniac who's paralyzed with terror over urban legends, was Ben's (Dylan McDermott) new patient. He had been afflicted by the Piggy Man legend. The Piggy Man- Kincaid Polk, was a hog butcher in Chicago during the 1903 Worlds Fair. The Piggy Man would wear a mask made from one of his slaughtered pigs and would kill people by gutting and skinning them upside down in a bathtub. Derek tells Ben that, if you stand in front of a mirror and say "Here Piggy Pig Pig," he'll return for the slaughter.
Fans speculated that the next episode preview of Chapter 9 had Taissa Farmiga appearing, wearing a blue jacket in the preview, and holding a selfie stick, although you can't see half of her face, fans could also tell by her hair.
Many of the camera angles make no sense in this episode as most of the characters are not depicted filming their point of views and the production certainly didn't mount that many cameras.
