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.
Continuity mistake: When Walt is sitting on the overpass it is clear that his car is parked on the part that straddles the median between the lanes, but when the shot is inside his car the view appears as if he is parked directly over the right lanes of traffic.
Continuity mistake: When Pinkman and White are having breakfast in the diner, the items on the table keep changing in each shot. Specifically, the jelly, the milk, the cup with the cream and, most noticeably, the rolled napkin with the cutlery inside: Sometimes folded, others opened.
Continuity mistake: When Mike and Walt and Jesse are driving toward each other in the desert and they both spin out to avoid a wreck, Mike can be seen leaving his Cadillac, which is in the middle of the road/tire tracks, and the front wheels are in the tire tracks. In the middle of the scene, the Cadillac has moved to the right slightly, but is still in the road. At the end of the scene when the three drive off together, the Cadillac is seen off the road, having moved significantly to the right without a driver present.
