Corrected entry: Jax pulls out 2 of another prisoner's teeth. You can't just put a handkerchief on your hand and pull out someone's teeth. Jax makes it look so easy. Your teeth don't just come out with a simple yank.
Corrected entry: When Jax is driving him and Gemma back from the county jail, Jax holds Gemma's hand in the car. The position of the transmission shifter is in the forward position - 'Park', showing the car is on a trailer for filming. (00:20:10)
Correction: There is no way to tell the shifter is in 'Park' since only the top part is seen/showing. This is just a guess. Although, from the looks of the top of the shifter, being aligned with the steering wheel and not further over to the right, it looks to be in 'Drive'.
Correction: Jax has just finished beating the guy and it is highly likely the teeth have been loosened.
