Continuity mistake: At the beginning of the episode when Bolsa writes "Hola DEA" with the white paint on the turtle shell, the writing completely changes from how it appeared in the episode "Negro Y Azul."
Negro Y Azul - S2-E7
Continuity mistake: When Jr. is talking about Raisin Bran not being the same as Raisin Bran Crunch, his hand is either by his mouth or lowered, depending on the shot. (00:30:30)
Cancer Man - S1-E4
Continuity mistake: When Mrs Pinkman says that feedback is very important, she has her hand up by her mouth. The shot changes, and now it is back down on the table. (00:24:15)
4 Days Out - S2-E9
Continuity mistake: When Walt gets the news about his tumour shrinking, Skyler gives him a hug. The camera changes, and she goes in for the hug again. (00:42:20)
Visible crew/equipment: At the very end of the episode, right after he tells Jesse how he used the red phosphorus to kill the gunmen, Walt leans down to vomit. You can see his microphone transmitter under his shirt. (00:54:20)
Visible crew/equipment: When Skyler is rubbing oil on her stomach and preparing herself in the bathroom, a camera and cameraman's hand is visible for about a second from the left side of the mirror. (00:10:30)
Green Light - S3-E4
Continuity mistake: In the scene where Walt is talking to Jesse in Jesse's car, when Jesse pulls out the bag of meth it is in a slide to seal bag. The bag changes between this and a regular ziploc bag from shot to shot. (00:19:30)
Visible crew/equipment: When Walter walks towards Jesse's house when he hasn't shown up for work a camera and boom microphone shadow is shown on his back. (00:40:10)
Continuity mistake: Mike Ehrmantraut takes Jesse to a house in the desert. He pulls up behind a dark blue car, which vanishes in the next shot, and then reappears.
Negro Y Azul - S2-E7
Visible crew/equipment: When we are shown the blue truck at the gas station, there is an entire film crew reflected in the chrome bumper. (00:18:15)
Character mistake: When Walt steals the bottles of "hydrofluoric acid," they are misspelled on the labels as "hydroflouric." This misspelling is corrected when hydrofluoric acid reappears in season 4. This was corrected for some DVD releases but is still visible on some streaming services. (00:11:20)
...and the Bag's in the River - S1-E3
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. (00:43:50)
Green Light - S3-E4
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. (00:35:10)
4 Days Out - S2-E9
Visible crew/equipment: When Jesse declares he's going to start walking and sits up in the cot, Walt reaches out to him and a boom mic is visible at the top of the screen. (00:34:25)
Green Light - S3-E4
Continuity mistake: When Mike gets out to throw Walt into his car the back passenger door is shut but when he throws him in it's open. (00:08:35)
Cancer Man - S1-E4
Continuity mistake: When Hank writes Icebreaker on the board, the writing changes drastically. Note the A. (00:00:30)
Character mistake: After Walt tries to slap the fly on the paper, he lifts his hand and the math is wrong on one of the sums. He has 6,012 + 7,287 = 13,301. But the actual answer is 13,299. (00:05:45)
Chosen answer: It is part of the ritual for la Santa Muerte. It is a sign of humility and sacrifice.
