Corrected entry: When Walt is building the battery and explains how it works to Jesse, he says that the cathode is the positive terminal. The cathode is always the negative electrode and the anode is always the positive electrode. Walt is a chemistry teacher who would know the difference. (00:37:15 - 00:38:30)
Corrected entry: In the desert, after Hank witnesses the head on the turtle, he runs off to his pick-up truck and catches his breath on the driver's side (left). The next shot is from behind the other cops grouped around the turtle. The vehicles can be seen in the background with Hank standing casually on the right hand side of the pick-up with the left door still open but no-one behind it. The shot then returns to Hank on the driver's side.
Corrected entry: In the opening teaser scene they show a man in a hazmat suit bagging evidence from the later revealed plane crash. One of the bags contain the eyeball from the pink bear. However in a future episode Hank discovers it in the pool filter, after the hazmat team would have bagged it. (00:00:55)
