Ozymandias - S5-E14
Visible crew/equipment: Skyler pulls up in her car at the home, talking to Walter Jr. about the truck in the driveway. During this scene the camera comes down to her side of the car. Its reflection is visible in the glass of the driver's side window. (00:32:50)
Ozymandias - S5-E14
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.
Chosen answer: It is part of the ritual for la Santa Muerte. It is a sign of humility and sacrifice.
