"The Ten Commandments Killer" is the eighth episode of the fifth season of the anthology television series American Horror Story.
There, behind the armoire, John finds the preserved body parts from the victims of the Ten Commandments Killer.
Sally convinces John that he is the new Ten Commandment Killer, following the path set by James March.
In the aftermath of Holden's disappearance, John frequently visits the Hotel to meet March and to continue an ongoing sexual relationship with Sally.
March also explains to him that the Cortez cannot be linked to the crimes, so John set up the lovers to stage their murder elsewhere.
"The Ten Commandments Killer" was watched by 2.31 million people during its original broadcast, and gained a 1.2 ratings share among adults aged 18–49.
