Other mistake: The bullet they pull out of Bobby is the entire bullet, casing and all, not just the slug.
One One Six - S6-E2
Continuity mistake: When the Sons are meeting with the Irish, Jax rides up on his motorcycle late to the meeting. He removes his helmet and his hat is backwards, revealing the Sons logo. In the next shot, when he's shaking the Irishman's hand, it's forward, then in the following cut back, it is backwards again.
Revealing mistake: When the police SUV is flipped, you can briefly see the cylinder of the air cannon used to do this on the underside of the car. (00:28:00)
Continuity mistake: When Happy is captive with the Chinese, there is a scene they are watching cartoons. Initially Happy is shown eating takeout without a drink. In the next shot, a beer is sitting on the box.
Visible crew/equipment: When Roosevelt is in Toric's room at the motel, you can briefly see a person holding a camera in the left mirror. (00:42:43)
Factual error: When Tara goes into her office there's dried blood on the carpet from her faked miscarriage. Considering it's a bio hazard that happened days ago it would've been cleaned up and sanitized since it's a hospital.
Suggested correction: The blood is on carpet which is very difficult to clean as it's such an absorbent material. The carpet will keep the stain, but as long as it has been thoroughly sanitised there is no issue here. Yes, the carpet could have been replaced, but hospitals don't generally keep spare carpets laying about. Plus the fact that her office isn't a treatment area, there isn't much of a hazard anyway.
Doctor's office with a blood stain on the carpet? Highly unlikely.
Highly unlikely doesn't make it a mistake.
Wolfsangel - S6-E4
Continuity mistake: Toric died with his eyes open. When the crime scene guy is taking pictures, his eyes are closed. (00:04:00)
Suggested correction: Otto cuts his throat, his eyes are open. The guards then shoot Otto and he slumps onto the bed then the floor. As the camera pans up to Toric, his eyes are shut. People don't die as soon as their throat is slit. It takes about 30 seconds.
