Revealing mistake: When Cameron gets Abel out of the car and starts running towards the boat, you can plainly see that he's not holding Abel, but a doll.
Small Tears - S2-E2
Revealing mistake: When Tara takes off the band aid holding Gemma's "wound" together, you can see its not a cut at all. Just a smear of blood.
Continuity mistake: When Jax goes to Cara Cara to find it burned down, he stands behind a line of yellow caution tape. In the very next shot it shows him several feet in front of it.
Falx Cerebri - S2-E6
Other mistake: Tara and Gemma are practising shooting. Tara is using a .38 which holds five rounds. She shoots all 5 rounds, then she shoots Ima's car 5 more times without reloading. (00:31:35)
Suggested correction: The barrel is open in her hand when she's shown then she fires at the car. One would assume the barrel is open to reload.
We hear Tara open the barrel when she and Gemma are watching Ima get out of the car and then it's a quick shot to her with the open barrel. There was no time to reload in that time.
Thank you Bishop.
Revealing mistake: When Opie breaks in to the lady's car at the store, he uses a tool that slides in between the door to pop up the lock. You can plainly see the door isn't locked in the first place.
Suggested correction: Opie was in a hurry and didn't check the door isn't locked. Not a mistake.
He used the tool to pop the lock that wasn't locked in the first place.
Continuity mistake: When Gemma pulls in in her her SUV outside Zobelle's store, her car is dry at first, then after she's been in that spot for a while it's wet like it's been raining, but other cars and the road are still dry.
Suggested correction: The road is wet, as is AJ's car. There is a patch of dry road where AJ's car was when he pulls away.
Albification - S2-E1
Other mistake: When Gemma walks over to Wayne sitting on the bench and says his name, the subtitles say Wade.
Continuity mistake: When awaiting news from the police station after the drug declaration, Jax throws his cigarette to his right when the camera is behind him. When the camera changes to show his front, he throws his cigarette again. (00:03:25)
Continuity mistake: Chibs starts the van and hears a bomb. He jumps out and starts running. He lands on the ground in a vertical position. When everyone runs over to him, he's lying horizontal on the ground.
Suggested correction: He does not jump. The blast from the explosion throws him into the air and he lands on his back. He is on his back in every subsequent frame until the rest of the Sons get to him.
