Continuity mistake: When Walt writes Chiral on the board, the writing changes style. Note the C. (00:09:20)
Cancer Man - S1-E4
Visible crew/equipment: When we see a close up of Jesse stamping on the spliff you can see an orange marker on the floor where Jake is stood. (00:42:20)
Visible crew/equipment: When Walter talks with Jesse outside the Mesa Credit Union, just after giving him the money to buy the RV, a boom mic pole can be seen reflected on Jesse's car door. (00:36:12)
...and the Bag's in the River - S1-E3
Continuity mistake: When Hank takes Junior to the motel to see how disgusting drug life can be, it is raining over Junior's shoulder when you look at the passenger window. But when you look at the driver's window from Hank's point of view, it is not raining. (00:21:30)
Continuity mistake: Emilio and Krazy 8 show up to the cook site to visit Walter. Krazy 8 leaves the drivers side door open when he exits the vehicle. Later when Walt is trying to flee the area in the RV, he drives past their car. The door is closed.
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)
...and the Bag's in the River - S1-E3
Visible crew/equipment: At the start when Jesse looks over his shoulder at Walt, a stage light and what appears to be a light screen are reflected in his mask. (00:02:00)
Visible crew/equipment: At the very beginning of the episode where the RV crashes against a rock in the middle of the desert, a camera badly hidden behind a bush can be seen on the right side of the screen immediately after the crash. (00:00:57)
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)
Visible crew/equipment: When Walter puts the mask over Jesse's unconscious face after drugging Emilio and Krazy-8, in the POV shot of Jesse where the camera is looking up at Walter, the reflection of the camera can be seen in Walter's mask. (00:51:05)
Continuity mistake: When Jesse picks up the apron and asks "What the hell is this", the apron is held so that part of it is placed over the top of Jesse's hand. When the camera changes angles, none of the apron can be seen placed over the top of his hand. (00:33:55)
Continuity mistake: When Jesse reminds Walter that he flunked him, he is holding a bottle of beer that is raised to his stomach. When the shot cuts, the beer bottle is lowered away from his stomach. (00:33:20)
...and the Bag's in the River - S1-E3
Character mistake: When Walt and Gretchen are talking about the elements in the body, they list hydrogen, oxygen, carbon, nitrogen, calcium, iron, sodium, and phosphorus. The percentage is short and she says "supposedly that's everything." But they don't count elements like sulfur (which has a greater abundance than sodium), potassium, chlorine, and magnesium. Even as college students, they would know those elements are in the body.
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)
Cancer Man - S1-E4
Factual error: Walt places a squeegee on the battery of a car to blow it up. This car is a BMW e36, which has the battery in the trunk.

...and the Bag's in the River - S1-E3
Continuity mistake: The position of Walt's right foot changes when he collapses. When he first collapses his foot is pointing toes away from his left foot. We then see Krazy8 stand up and now Walt's right foot is pointing toes towards his left foot. (00:23:10)
...and the Bag's in the River - S1-E3
Continuity mistake: Walt writes a list with the title "let him live." The position, style and size of the writing changes from when he writes it to when we see the list with 2 entries on it. Note the T in "let" has moved off the margin line. (00:20:10)
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 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)
Chosen answer: It is part of the ritual for la Santa Muerte. It is a sign of humility and sacrifice.
