Continuity mistake: The position of Cousin's white headband and the way it is tied vary, even though there is a tight knot at the center of his forehead that prevents such changes. The straighter part of the bow, to his right, is diagonally upward at a ~ 60° angle and the left side is more ear-like and parallel to the floor. Next, the left side is diagonally upward at a >60° angle and the right side is shorter and more parallel to the floor. A little later, the left part is shorter and the right longer, sloping down.

Continuity mistake: Before "The Bailiff" shocks Killjoy in the chair, the skin above Killjoy's left lip is visible, not painted solid white like the rest of his face. Going down the elevator, that section of his mouth is uniformly painted white. (00:20:55 - 00:22:32)
