The Incinerator Room Was Modeled After a Concentration Camp
The second episode introduced viewers to the incinerator room by panning on the exterior of the room with the flames visible through a rectangular window. It turns out that the design of the room was modeled after the incinerator room at the Auschwitz concentration camp.
Ominous music plays in the scene as boxes with pink bows are brought into the room to get incinerated. In another episode, a drop of blood pops out of a box, but one of the workers simply drills the box shut and tosses it in the incinerator.
