Factual error: When going over the logistics of the plan to kill the ten men in prison, Jack tells Walt that killing Osama Bin Laden was less complicated. Breaking Bad takes place over a period of two years, beginning with Walt's birthday in 2008, and ending on his birthday in 2010. Bin Laden wasn't killed until May of 2011. (00:15:23)
Plot hole: Preparing to steal methylamine from the train, Walt, Jesse and Mike measure off a predetermined distance from the railroad crossing, which happens to coincide with a handy arroyo, where they bury their tanks. Problem is that they couldn't have known that distance (calculated by knowing the position of the methylamine tanker car in the train) until Lydia told them. But she didn't call that info in until the night after they'd already buried the tanks.
Factual error: In the opening scene for the episode, a character commits suicide by electrocuting themselves with a defibrillator. The device used was an AED (automated external defibrillator) which analyses the electrical rhythm of the heart and only delivers a shock when the heart rhythm is ventricular tachycardia or ventricular fibrillation. In this case, the device would not have delivered a shock as the person did not have both ECG electrodes attached and therefore would not have detected a cardiac rhythm. The person would also have had a normal heart rhythm.
Continuity mistake: In the scene where the shootout starts in the previous episode, Walter is handcuffed in the back of the SUV and trying to get to the floorboard to avoid the gunfire, and his glasses eventually fall off. After the gunfight when he is yelling at Jack from the back of the SUV, his glasses are back on his face, which would be hard to do handcuffed.
Visible crew/equipment: In the flashback scene where Jesse breaks into the Whites' house and starts pouring gasoline everywhere before Hank stops him from burning the house down, you can see the outline of a crew member exiting the right side of the dark living room at the beginning of the shot. (00:21:35)
Continuity mistake: When Jesse is lying on the rotating disc at the beginning of the episode, in the initial side view Jesse's head doesn't reach the centre of the disc. However, when they switch to an aerial view from the top down, he is lying on the exact centre. Presumably, Jesse's feet couldn't reach the ground to rotate the disc when he put his head on the exact centre.
Audio problem: After Hank and Gomez separate Jessie and Walt after he's arrested, Hank tells Gomez that "I'll call the Tribal Police on my way out, let them know we're here." During the middle of this line, the shot cuts to Walt and you can distinctly hear the sound of a microphone picking up the actor breathing on it as he recorded this line in ADR.
Continuity mistake: Out in the desert, Hank yells at Walt to drop his gun. Walt, in a frontal shot, extends his arm out to his side and lets the gun drop. When it changes to a low angle from behind Walt, suddenly this same arm and hand are down at his side instead of extended out.
Continuity mistake: In the car when Walt meets up with Saul and discusses "Old Yeller" Walt asks what he means and is looking at Saul. When it cuts to a close up of Walt, he's suddenly looking more straight ahead or towards the driver, only then to turn his face to Saul.
