New this month Continuity mistake: Walt is driving down a deserted road singing "A Horse with No Name." You can see the roadway behind him through the hole in the headrest. At first, the road is empty. But then a white vehicle quickly approaches. The camera angle changes and there are no vehicles behind him, but a police car coming from the opposite direction passes and makes a u-turn. When the camera angle is back inside Walt's car, the white vehicle turns out to be the police car that just made a u-turn.
New this month Continuity mistake: With the camera angle aimed up through the pan, Jesse cracks an egg into a transparent corning skillet. The yolk breaks and starts to run. The camera angle changes to above the pan as Jesse cracks a second egg. Both egg yolks are now intact.
Revealing mistake: At the end of the episode when Tuco shows up at Walter's house in the backseat of Jesse's car, he tells Walter to get in. As they drive off, the shot pans out to show the street sign across from Walter's house. The sign says Piermont, which is the real name of the street. In the show, the Whites live on Negra Arroyo Lane.
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.
Character mistake: When Hank is brought to the hospital with gunshot wounds, the ambulance and its two EMTs are met outside by two doctors. One doctor says "Let's get him two grams of oxygen. What's his hemoglobin?" This episode's technical adviser was perhaps away for this scene. How much exactly is two grams of oxygen? Orders for administering oxygen would be given in liters, such as two liters per minute (LPM). The line is presumably meant to be 'two liters of oxygen'.
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.
Character mistake: When Walt is in the bathroom using hydrogen peroxide to clean his leg wound he received from killing Crazy 8, he notices blood on his pants. He tries to clean the bloodstain off with a toothbrush. I think that any and EVERY chemist would know that hydrogen peroxide almost instantly removes blood stains from clothing. But, instead of using this somewhat common knowledge, Walt scrubs the stain with a toothbrush under the sink. Even if he had never heard of this 'trick', given the nature of H2O2 and Walt's understanding of chemistry, he would have realized this chemical solution immediately... Especially since he used the peroxide seconds before discovering the blood stain.
