Other mistake: Abel was 18 months old when Thomas was born. All through the series, Thomas hardly ages. In season 7 Abel is 5 and in kindergarten yet Thomas looks younger than 3. He's not even walking or talking yet! Thomas should be at least 3 years old according to the time span of the series.
Sons of Anarchy (2008)
1 other mistake in show generally - chronological order
Starring: Charlie Hunnam, Katey Sagal, Kim Coates, Mark Boone Junior
Visible crew/equipment: When Jax and Clay are meeting with Alvarez (when they figure out the niners are branching out), the camera man is visible in Alvarez's sunglasses.
Trivia: Jax (Jackson), is Katey Sagal's sons name in real life.
Question: Does anyone know why Piney wears a jean vest instead of leather like the others?
Chosen answer: The First 9 wore these, as can be seen on old pictures. They later switched to leather, but Piney just never did.
