Continuity mistake: When Walt writes Chiral on the board, the writing changes style. Note the C. (00:09:20)
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)
Continuity mistake: Jesse is applying foundation to his eye to hide the bruising. He is then interrupted by Crazy 8 emerging from the RV. He then runs down to the RV and upon arriving at it, the foundation has covered a lot more of the bruise. (00:11:45)
Continuity mistake: When Jesse looks out the window at the RV, the door is wide open. When he gets outside, the door isn't open as wide. (00:11:50)
Continuity mistake: When Jesse looks out of the bathroom window there is a little curtain across the bottom half of the window. From the shot inside the bathroom the curtain is opened however from the outside it is closed. (00:12:00)
Continuity mistake: When Krazy8 falls to the floor, his position on the floor changes between shots. Notice his right arm in relation to the curb. (00:13:20)
Continuity mistake: When Skyler is looking at Cap'in Cook's My Shout page, you can see the whole page. Camera cuts and now the page has zoomed in significantly. (00:14:30)
Factual error: Jesse's home number is (505) 148-3369. However, US phone numbers can't have an exchange that starts with 1. (00:14:30)
Character mistake: When Skylar types in the phone number, the paper reads "505-148-5039," but on the computer she types "505-148-3369." (00:14:30)
Visible crew/equipment: Just as Walt is saying the line about checking to see if the other one is dead in the RV, the edge of the set comes into view very briefly on the right hand side. (00:15:10)
Continuity mistake: When discussing what Crazy8 is capable of, Jesse has his hand by his head. Camera cuts and it's disappeared. (00:16:20)
Continuity mistake: When Walt realises that Krazy8 is awake in the basement, Krazy's foot is sideways showing the tread of his boot. When the camera shows Krazy from the front, his boot/foot is now flat on the floor as it should be. (00:26:40)
Revealing mistake: Walter is in the basement and slides two bottles of water and a plate with a sandwich across the floor to give to Krazy-8. Right before he slides the plate across the floor, the camera wobbles slightly. (00:28:25)
Continuity mistake: Just as Skyler asks Walt who Jesse is, her hands go from curled up on her legs to palm flat on her legs. Her t-shirt also has a ridge in it across the belly which disappears in the second shot. (00:33:20)
Continuity mistake: We see Jessie with the torch to his pipe. Camera cuts and the torch has disappeared. (00:37:30)
Continuity mistake: Skyler tells Jessie not to touch her. When she does she has her hands on her belly in the front shot and one raised in the over the shoulder shot. (00:39:00)
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)
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)
Continuity mistake: At the end when the girl puts the mask on there is a bit of hair hanging over the front of the mask. Camera changes and the hair has disappeared. (00:46:10)
Chosen answer: It is part of the ritual for la Santa Muerte. It is a sign of humility and sacrifice.
