Continuity mistake: When Jax injects Wendy with the heroine in the previous episode, he puts the needle in the side of her shoulder, yet when she shows the bruise to Tara in this one, it's on the front.
Visible crew/equipment: When Jimmy Smits and Dave Navarro are talking to the shopkeeper, a microphone wire can be plainly seen under Navarro's wife-beater. (00:14:25)
Chosen answer: The First 9 wore these, as can be seen on old pictures. They later switched to leather, but Piney just never did.
