The Beating - S3-E7
Continuity mistake: Near the end of the episode, Kayce has tracked his stolen cattle to a trailer. He bangs on the door, identifying himself as a livestock agent. The lock clicks audibly, so Kayce runs around back where a gunfight ensues, and he kills the cattle thief. Moments later, he is back on the other side of the house where he was knocking and hears a child's scream. Rather than running back around to the side of the house where the dead guy is, he enters the now unlocked door to find a little girl crying over the dead guy.
Continuity mistake: When the bikers are grilling on the ranch, there are only 10 bikers. Butin the various shots that show the bikes, there are 12 bikes (2 groups of 6).
