Season 4

Jesse follows Walter’s instructions and murders Gale. Gus decides to discipline the two by enforcing stricter policies at the lab. He also tries to break Walter and Jesse’s friendship by assigning them to separate work details. While Walter works in the meth lab, Jesse escorts Mike (Jonathan Banks), one of Gus’s enforcers, to retrieve payments and provide back-up. Walter and Jesse become increasingly distant from, and hostile to, each other. Meanwhile, Hank, who has been recovering from his last engagement with the cartel, finds evidence linking Gale to Gus. He believes Gus is a major drug distributor and starts looking for tangible evidence to file charges. Gus realizes Walter’s close ties with Hank could jeopardize his entire operation. Gus fires Walter and threatens to kill his entire family. Jesse and Walter put their differences aside and agree to murder Gus, convincing former cartel enforcer Hector Salamanca to detonate a suicide bomb; Hector succeeds in this endeavor, killing himself, Gus, and Tyrus, Gus’s henchman. Walter and Jesse then destroy the meth lab and Walter declares to his wife, “I won.”
