Continuity mistake: When Jax and his crew meet up with a Hispanic gang to sell them guns and are outnumbered, they run in the station wagon. The run the station wagon through a gate and roll it, destroying the front end, but magically the station wagon's front end appears with little damage afterwards.
Continuity mistake: In the episode prior to this one, Clay severely beat Gemma in the face. Bruised and cuts. Swollen eyes. This episode, which is the next morning, her face isn't nearly as bruised - it sure wouldn't have healed that much overnight. And the swollen eyes aren't as bad either.
Revealing mistake: In the scene where Jax and crew go to help escort Tig after he ran into Laroy with a car at the cafe, they get caught in a traffic jam and have to drive on the breakdown lane. Jax shoots at the SUV with Laroy and kills the driver and the car slams into a car that is stuck in traffic, but there is no one sitting behind the wheel of that car.
Plot hole: Tig thinks it's Opie driving the truck. Problem: When Donna stops at the stop sign, Tig has a clear view of the driver. Also, when he pulls up behind her, it's obvious that Donna is much shorter than Opie and isn't wearing a hat like Opie always does. Tig doesn't realize it's Donna until he pulls up beside her.
