Crazy Handful of Nothin' - S1-E6
Continuity mistake: Tuco puts the money in the bag and hold it out for Jessie. When the camera cuts to a different angle the way Tuco is holding the bag has changed completely. (00:30:00)
Gray Matter - S1-E5
Continuity mistake: When Jesse spots Badger he is in the sun. Camera cuts to Badger running over to him and he is now in the shade. (00:01:20)
...and the Bag's in the River - S1-E3
Continuity mistake: When Walt collapses we see the blood stain on the floor is a deep crimson. When he collects the bits of plate, the stain is very faded, even though only a few minutes has passed.
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)
Continuity mistake: When Emilio's body crashes through the ceiling and lands on the downstairs floor, there is one huge chunk of carcass that lands on the floor in one piece. When the remnants of the body are shown from a different angle, they have been replaced with numerous, smaller chunks. (00:45:30)
Gray Matter - S1-E5
Character mistake: The actor that plays Walter Jr. is laughing in the scene where they confront Walter about treatment. Hank is reaching for items from the cheese plate and RJ Mitte is trying to hide his laughter. (00:25:30)
Revealing mistake: When Jesse puts Emilio's dead body in the bathtub and we see a view from below, Emilio blinks. (00:42:27)
Revealing mistake: Emilio's eye twitches when the gun is dropped on the bottom of the bath next to his head while he is supposed to be dead. (00:42:54)
A No-Rough-Stuff Type Deal - S1-E7
Continuity mistake: While Walt and Jesse are talking with Tuco at the junk yard for first time, the sun changes between shots.
Crazy Handful of Nothin' - S1-E6
Continuity mistake: When we see the red liquid being injected into Walt, there is a lot of liquid in the syringe. Camera cuts and there is suddenly much less. (00:18:10)
...and the Bag's in the River - S1-E3
Continuity mistake: When we see the basement while Krazy-8 is alive, we can see that there is no light coming in from outside or any windows. When Jesse returns and goes to the basement all of a sudden there is loads of daylight streaming into the basement. (00:42:10)
...and the Bag's in the River - S1-E3
Other mistake: Walt pushes water jugs and several items toward Krazy 8 who is locked in the basement. Notice the ground has been disturbed where the jugs slide, indicating previous takes.
Chosen answer: It is part of the ritual for la Santa Muerte. It is a sign of humility and sacrifice.
