The Bug

Three years after her selfless act to save her family, Nancy is released early from Danbury prison and paroled to a halfway house in New York City. She learns that Esteban was killed in prison and his drug cartel has disbanded. After talking with Jill and Stevie via Skype, she sets out on a scavenger hunt at the behest of her romantic partner from prison. She takes possession of a cache of military-grade weapons hidden in a car trunk. Andy, Shane and Doug, who are living new lives in Copenhagen, return to America upon learning of Nancy's release. Silas returns to New York as well to work on his modeling career.

Walt drives to Gus's restaurant with an eager Hank to retrieve the tracking bug he left on Gus's car. Hank's suspicious when the bug only shows Gus driving between home and work: "He's so clean he must be dirty." Skyler is alarmed when Ted, whose company's cooked books Skyler signed off on, visits to tell her the IRS is auditing him. She pretends to be his ditzy, untrained accountant, putting off the investigation so long as he pays the fines and back taxes, which Ted tells her he doesn't have the money to do. Hank's research uncovers Gus's depot, so Jesse is brought in to help clean and move all the product out of it. While there, one of the cartel's top lieutenants, sniping, kills one of the workers, but Mike pulls a shock-stilled Jesse to safety. Gus calls the cartel, giving in to their demands; Gus invites Jesse over for dinner and asks him if he can cook Walt's formula. The next night, Jesse calls Walt to come over; he then explains that Gus is sending him to Mexico to show the cartel how to cook Walt's formula. Walt responds by asking him if he poisoned Gus; Jesse says he didn't see him. Walt knows he saw him, he says, because he put a bug on Jesse's car that showed he was at Gus's. Jesse, furious at Walt's distrust, throws the bug at him, cutting his forehead open. The two fight and Jesse gets the upper hand, punching Walt repeatedly in the face, then telling him to leave and never come back.
