This all makes sense, and it goes hand in hand with my understanding of how effects are usually added. I was hoping for an answer that was specific to Breaking Bad, though -- maybe a behind-the-scenes clip or one of the creators talking about it.

@ChristianRau Well, that's the thing. I couldn't find a good plot summary (in English), and I feel a second viewing would be more helpful once I have read a summary.

@ChristianRau understood. I was looking for guidelines on specificity in the help section of this SE, but didn't find much of use (perhaps this is a discussion more suited to meta). My dilemma is, if I didn't understand really what was going on or who was doing what, I can't really ask more specific questions.
