Walt uses a remote-controlled machine gun rigged in the trunk of a car to massacre Jack’s gang. He finds Jesse, a beaten, emaciated slave. Jesse refuses to kill Walt. Walt asks Jesse to shoot him, but Jesse just says, "Do it yourself." Walt then tells Jesse that he watched Andrea die—and that Todd killed her. Jesse strangles Todd with his own chain. As Jesse escapes, Walt is shot by a fragment of his own machine gun. He wanders into the lab.
Walt, Jesse, and a resentful Mike go into business together. They need a new distribution network. Walt approaches Lydia Rodarte-Quayle, a nervous, high-strung Madrigal Electromotive executive (Gus’s parent company). She connects them with Declan, a local Phoenix kingpin. Declan laughs at Walt’s proposal of $15 million for the methylamine. Walt coldly retorts, "Then I’ll just cook my own." He buys a Vamonos Pest control company as a front, cooking in the tents of fumigated houses while the owners are away. breaking bad season 5
Their methylamine is running out. Declan cuts off supply. Lydia suggests stealing a tanker car of methylamine from a passing train. The plan is a masterpiece of precision: Walt, Jesse, and Todd (a bug-eyed, polite, sociopathic pest control worker Jesse brought on) must drain the car while the train is moving, replace it with water, and vanish within 90 seconds. They succeed perfectly. As they celebrate, a kid on a dirt bike, Drew Sharp, appears from the desert, having witnessed everything. Before anyone can react, Todd calmly draws a pistol and shoots the boy dead. Walt uses a remote-controlled machine gun rigged in
Jesse is shattered. He has a full-blown breakdown. Walt tries to rationalize it as "necessary," but Jesse sees the truth: they are now monsters. Walt tries to get Todd’s uncle, Jack Welker (a white supremacist prison gang leader), to handle the methylamine distribution, cutting Mike out. Walt asks Jesse to shoot him, but Jesse
Mike decides to "retire" by selling his share of the methylamine to Declan for $5 million. Walt demands Mike give him the names of the nine lawyers who handle the hazard payments. Mike refuses. A heated argument ends with Walt pulling a gun. Mike taunts him: "You just had to be the man. You just had to win. You couldn't let it go. You're not half the man Gus was." Walt shoots him. Then, in a moment of haunting humanity, Walt realizes he could have gotten the names from Lydia. Mike dies alone by a river, telling Walt to "shut the fuck up" and let him die in peace.
