At the high school, Walt and Skyler attend a PTA meeting concerning the chemistry lab thefts. Seated next to each other, Walt begins to stroke Skyler's thigh under the table. She resists at first but then revels in the erotic moment, which is cut short when Walt is called upon. Later in the parking lot, the two have sex in Walt's car. Skyler wonders why this tryst felt especially good, to which Walt replies because it was illegal.
While a realtor shows Jesse's house to a couple, Walt arrives and looks for Jesse. Walt finds him in the RV, his ribs still bandaged from his run-in with Tuco. Walt hands Jesse his cut from the deal with Tuco, but Jesse is unhappy to learn that the deal requites them to make two more pounds of meth. Jesse mocks Walt's "brilliant business plan," saying that it's almost impossible to procure enough pseudo to produce that much meth.
At a meeting with Dr. Delcavoli, Skyler notes that Walt's color is better and that he has become more sexual since starting his treatment, and expresses interest in alternative therapies. Dr. Delcavoli says they're fine as long as they don't interfere with his treatments.
Walt arranges to meeting with Tuco at a junkyard. When Tuco arrives, he is displeased to learn from Walt that there were "production problems," handing him far less than the two pounds he was expecting. Tuco says he thought Walt was a player, but Walt holds his ground and dares to ask for more money, proposing that Tuco consider it a capital investment. The two men work out a loan at twenty-five percent weekly interest. Walt ups the ante by asking if Tuco wants four pounds instead of two. Tuco agrees but delivers a stern warning: "Talk is talk. But owing me money, that's bad."
Back at his house, Jesse frets that it'll take "two, three hundred boxes of sinus pills" to make four pounds of meth. Walt says they'll produce their own ingredients, but when he hands Jesse a list of chemicals and equipment to buy, Jesse tries to back out. It is after Walt encourages him to believe in himself that Jesse agrees to take on the endeavor.
At a festive baby shower held at the White residence, Skyler is shocked by Marie's gift: an expensive baby tiara. Hank and Walt go out by the pool to share Cuban cigars and stiff drinks. Hank explains that he did a little favor for an FBI colleague to get the cigars, which are illegal. The men talk about what's legal and illegal; when Walt concludes that "it's arbitrary," Hank replies that a lot of guys in jail talk like that and says that sometimes stuff that's legal shouldn't be. That night, Skyler talks about returning Marie's gift. Walt switches the subject to alternative medicine and talks about going to a Navajo sweat lodge for the weekend.
After Walt arrives at Jesse's house, he congratulates Jesse for scoring the supplies, though a key chemical -- methylamine -- is missing. Jesse has found some professionals who can steal it from a warehouse, but they want $10,000 for the job. Seeing one of Junior's old toys on a shelf in the garage, Walt suggests they steal it themselves.
In Jesse's kitchen, Walt extracts the aluminum powder from Etch-a-Sketch toys, and mixes it with powdered iron oxide to make thermite, which produces a surface temperature high enough to melt through four inches of solid steel, and thus will break any lock that the warehouse is likely to have on its door.
Later, at a jewelry store, Skyler attempts to return the tiara, but instead of getting cash back, she is detained for shoplifting. Skyler tries to explain that the tiara was a gift, but the owner says he's pressing charges. Thinking quickly, Skyler threatens to call the local TV news and fakes going into labor. After bluffing her way out of the store, she angrily phones Marie.
That evening, after locking a guard inside a portable toilet, Walt and Jesse break into the warehouse and, despite a few glitches, pull off the heist and steal a drum of methylamine. Unfortunately, the RV fails to start the next day, forcing the duo to cook in Jesse's basement. Even more unfortunate, the realtor has scheduled another open house. Walt tells Jesse to get the visitors to leave while he tries to cook. When one of the buyers insists on inspecting the basement, Jesse pushes him back into the kitchen and announces the house is not for sale anymore.
Meanwhile, Skyler chases down Marie at a women's clothing boutique, asking her why she stole the tiara. Marie denies Skyler's accusations and says she doesn't know what her sister is talking about. When Walt comes home, Skyler explains the situation and criticizes Marie for refusing to admit to her wrongdoing, to which Walt says that people sometimes do things for their families. Skyler asks if that justifies stealing. Walt asks what she would do if it were him, and asks if she would divorce him or turn him into the police. Skyler warns him that "you don't want to find out".
The following day, Walt and Jesse meet Tuco again at the junkyard. When Tuco becomes curious to know why the meth is blue, Walt tells him that they used a different process. Sampling the product, Tuco is ecstatic about the results. However, when one of his henchmen presumes to speak for him, Tuco viciously attacks him, showing Walt and Jesse his bloodied knuckles. The duo look on, horrified by the scene. Finishing up, Tuco laughs and tells a bewildered Walt that he'll see him next week.
