Continuity mistake: In the scene with the horse trainer, the character has a wedding ring on, then doesn't, then does, and finally doesn't again. (00:30:40 - 00:32:50)
Continuity mistake: As Raylan sits down opposite the thug, who says "I just take orders", his gun is held vertically. Cut to a shot from the front and it's on its side. (00:25:00)
Continuity mistake: Ava spills Coke on her blouse and creates a big circular stain. As she walks to the bathroom, the stain becomes a long narrow one. When she is leaving the pizza place, the stain is still narrow, but much shorter. (00:21:00 - 00:22:00)
Chief Deputy Art Mullen: Just what part of "under investigation" confuses you?
Raylan Givens: So many things confuse me, Art.
Question: Mags poisons herself with the same "it was in the glass, not the jar" approach she took with Loretta's father. But we see her grab two glasses - one from the cupboard and one off a shelf. Does she slip poison in while off camera, or is it just that the cupboard/shelf glasses are always poisoned, trusting that everyone knows not to use them? Seems like a crazy risk to take.
