This Breaking Bad episode was interesting, because of the way it fleshed out Gus’s backstory. We see Gus and his original cook approach the runners of the Mexican cartel. He gets them interested in the production and marketing of meth instead of cocaine. They can keep all of the profits and be more than a middleman. The old man who warned Tuco with the bell is present for the pitch. In the end, Gus’s partner gets gunned down in front of him, and we see Gus vulnerable for the first time. His partner’s blood pours out into the swimming pool and the camera closes in on the blood blending with the water.
