Revealing mistake: When Nero and Gemma are talking, a woman can be seen in the background moving a paint roller up and down without actually touching anything. (00:54:45)
Other mistake: When Patterson goes to see Wayne, he says that there is no one from SAMCRO at TM, but as they are talking, you see someone wearing a SAMCRO cut in the background. (00:43:15 - 00:45:10)
Chosen answer: The First 9 wore these, as can be seen on old pictures. They later switched to leather, but Piney just never did.
