Todd cooks a methamphetamine batch of only 76% purity and not the distinct blue color expected by European customers. Lydia comments that consumers expect the “blue”, which is a signal of quality and purity, and will pay top dollar only for it. So while even though they are getting better, they aren’t as good as Walter’s blue meth. The blue coloring is important to signal to the European market that the product is high quality (even though it isn’t). If customers believe the meth is the same, they will pay top dollar for the product. Lydia recognizes that without the color, her profits are about to fall.
This clip shows Jesse interviewing for, what he thinks it is, a standard sales position. However, he soon finds out that he is in for a sign-twirler job. Nevertheless, the employer would have considered Jesse for the sales position if he possessed the required skills (i.e., a sales license, two-year and on-the-job sales experience, and a college degree). Even though Jesse has significant (on the street) sales experience, he is not qualified for the standard sales position he thought he applied for. Since Jesse lacks the prerequisite skills, he must continue to be frictionally unemployed (until he can find a suitable position).
There’s an arrest on school property, and Hank shares why he believes the janitor was responsible for the recent thefts at the school. The theft corresponds to popular equipment used to make meth, and the janitor (Mr. Archilleya) had a past record for possession of marijuana, had access to the school, and during a search of his vehicle, had possession of marijuana. Skyler is confused how Hugo could even get a job at a school with his record, but Walt notes Hugo doesn’t seem like a drug dealer. This is a classic example of mixing correlation with causation. Just because Hugo has markers that could potentially make him a criminal, it doesn’t mean that it would cause him to be willing to steal from his employer. Society often mixes correlation with causation, which results in some unfortunate outcomes.
