New this month Continuity mistake: While Walt is out of his car and arguing with the police officer, there are other cars visible in the far distance behind him. The cars appear and disappear in between shots, there isn't time for them to pass and we don't hear them pass.
New this month Continuity mistake: When season 1 left off, at the very end of the last episode, Tuco examines the blue meth seriously and says, "What is this shit? This is blue." At the start of season 2, the scene is repeated, only when Tuco sees the blue meth, he laughs and then says "What is this? It's blue." Even though its supposed to be the same scene, the dialogue is slightly different and Tuco's demeanor is completely different.
New this month Continuity mistake: When Walter drops the plate, it shatters into four pieces, with one piece sliding to the edge of the frame, where it stops without splitting further. The other three are in clear view and are in three intact parts. We cut away and back, and now the piece on the right is suddenly shattered into several smaller pieces. Also, the fourth piece that slid out of frame is still there when Walt wakes up, and he picks it up with the rest. The piece that Krazy-8 grabbed was too small to be one of the original four pieces the plate split into, and the piece closest to him didn't shatter further. In addition, when Walter reassembles the plate, the pieces don't match up with what they were in the basement. After the mysterious second shattering, there should be 8 total pieces of plate. If the piece Krazy-8 grabbed broke off from another part, that would mean 9 pieces. Yet Walt's reconstructed plate has only 6 parts plus the gap for Krazy-8's piece. Also, the final plate has smaller pieces at opposite ends, which wouldn't be possible given where the quadrants broke. Walter reassembles the plate upside down, so the part on top to the left of the gap (combined with the piece that is missing) is likely the piece that slid toward Krazy-8. So the large solid piece to the right of the gap would have been the piece that shattered into 5 pieces, but it is intact here. There is also a smaller piece between the piece Krazy-8 could have broken his piece from and the piece next to it, but this piece couldn't have come from either piece when the plate broke or if Krazy-8 broke his piece off the other piece. When Walter picked the pieces up, the piece closest to Krazy-8 was a single piece.
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 Hank is standing between the ATM and the pumps at the gas station, the shadow cast by the roof over the pumps shifts between shots. The shot from away, taken next to the pole with the Indian logo was taken earlier in the day, casting a long shadow. The other shots have a higher sun which has moved by several hours.
