Factual error: When Elizabeth asks Zeb how Vanessa can be happy, Zeb has his old catalog with a bunch of flower seed packets on his lap, and as they both hold up the packets, particularly Elizabeth, the modern Universal Product Codes are at the back of the packets.

Visible crew/equipment: After Jim-Bob gets home he and John talk for a bit, then just as Jim-Bob walks behind his father and says, "I hope you find your fishing pole," the arm of a crew member is visible at the right side of the screen. (00:08:10)
The Recluse - S6-E3

Visible crew/equipment: Near the end, while John is working alone in the mill Ben shows up, and when Ben asks, "Need some help," a crew member is hiding behind the stack of drawers, toward the right side of the screen. It's not Zeb or Easy or any family member. (00:46:30)
