Plot
After receiving an anonymous warning from Saul Goodman about Hank Schrader having been targeted by a drug cartel, the DEA dispatches a squad of agents to guard Hank and Marie Schrader's house. The White family is also brought to the Schrader household for protection, but Walter White convinces Skyler White to let him stay behind at their own house, ready to face the consequences of his actions. Walt sits nervously in the backyard, spinning a gun on the table that keeps pointing at him, but takes note when it points at a potted plant. Hank deduces that his investigation of Gus Fring is the reason for the threat on his life, so he asks Steven Gomez to search the industrial laundromat for him.
Gomez and an officer with a drug-sniffing dog later check out the laundromat but do not find anything, although Jesse Pinkman and Tyrus Kitt were below them in the hidden meth lab. Gus, in a phone call to Jesse, implies the police attention is Walter's fault, and Walter must be killed to protect the operation, but Jesse again refuses to cook if Walter is killed. Saul later hands Jesse's entire share of the meth profits to Jesse, since Saul is planning to temporarily flee Albuquerque until the feud between Walter and Gus is over. Saul reveals that Gus took Walter to the desert and threatened his family, a revelation by which Jesse is taken aback. Jesse later receives a call from Andrea Cantillo that her son, Brock Cantillo, has become seriously ill and is in the hospital. Jesse discovers that the ricin cigarette, which he kept handy to poison Gus, is missing and concludes that Brock somehow ingested the ricin.
Jesse confronts a paranoid Walter at the Whites' house. Jesse grabs Walter's gun and points it at him, accusing him of poisoning Brock out of spite. Walter claims that Gus must have planned Brock's poisoning and framed Walter for it in order to manipulate Jesse into killing him; the cameras around the lab probably spotted the cigarette, and Tyrus must have taken it out of Jesse's locker, tracked down Brock, and poisoned him.
