Audio problem: The message from Walt that Skyler listens to at the office is different from the audio earlier in the episode. Walt says "no" when we see him, but on the recording he doesn't say it.
Continuity mistake: In her office, Skyler brings up to her boss, Ted, an issue with a "Keller Account" and puts one hand up to her mouth. In this shot her other arm is crossed over with her other hand resting on the one arm held up. When the angle changes suddenly her arm is outstretched more in front of her with her hand on her papers.
Continuity mistake: Walt Jr. throws up the alcohol into the pool and some of it gets on the side walls. In the wide shot this has all disappeared.
Continuity mistake: With the camera angle aimed up through the pan, Jesse cracks an egg into a transparent corning skillet. The yolk breaks and starts to run. The camera angle changes to above the pan as Jesse cracks a second egg. Both egg yolks are now intact. (00:16:00)
Continuity mistake: When Flynn is eating his bacon breakfast, as the camera shots change, he keeps picking up the fork he already picked up in the previous shot. (00:02:35 - 00:32:00)
Continuity mistake: Skyler and Ted talk about the churros and party. Behind Skyler, the power sockets are not being used. The shot after, they are. (00:20:15)
Chosen answer: It is part of the ritual for la Santa Muerte. It is a sign of humility and sacrifice.
