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)
Other mistake: At the end of the previous episode, the ornate SAMCRO table is shown in the ice cream shop clubhouse. Then in this episode, the same table is in the Red Woody meeting room. Can't be a second table - it's got the original's burn damage from the season 6 clubhouse IRA bombing.
Chosen answer: The First 9 wore these, as can be seen on old pictures. They later switched to leather, but Piney just never did.
