After Walt's car bombing plan fails, Jesse is brought in for questioning by detectives because of his remark that Brock may have been poisoned by ricin. Walt pays a hefty bribe to Saul's secretary to get in touch with Saul, and with Jesse's help they realize that Gus may be vulnerable if he visits Hector at the nursing home. Walt visits Hector and offers him a chance for revenge against Fring: "I know that you despise me, but I'll bet that I know someone you hate even more." Hector then requests a meeting at the DEA office, but tells them nothing; he only crudely insults Hank. Tyrus has been tailing Hank and sees Hector leave the DEA office, and informs Gus. Jesse is released after no ricin is found in Brock's bloodwork. As he leaves the police station, Jesse is kidnapped. Tyrus visits Hector's room and sweeps it for any bugs; he informs Gus that it's clean. Gus arrives and berates Hector for speaking to the DEA, calling him a "crippled rata" and prepares to kill him. Hector finally looks him in the eye and then rings his bell, detonating a bomb that he has allowed Walt to plant in his wheelchair. The door is blown off of the room and Gus walks out into the hall and straightens his tie, apparently unharmed. The camera angle changes, revealing that Gus has been mortally injured, the entire right side of his face having been blown off. Gus falls to the floor, dead. Jesse is working at the lab under duress and under guard, when Walt arrives and executes Jesse's two captors. Walt and Jesse then flood the lab with chemicals and set it ablaze, wiping their fingerprints off the door as they leave. Later, Walt meets Jesse at the hospital parking garage, and Jesse tells him Brock's going to pull through and was poisoned by a Lily of the Valley plant, not ricin. When Jesse leaves, Walt calls Skyler, who's watching coverage of the nursing home bombing on the news. She asks, "Was this you?" Walt replies, "It's over. We're safe. I won." As he leaves the parking garage, he smiles at Gus's car, still parked there. In the final scene, on the deck of Walt's swimming pool, the camera slowly zooms in on a potted plant—a Lily of the Valley.
