Walt and Jesse struggle to obtain sufficient pseudoephedrine pills for large-scale production, forcing them to find alternative precursor chemicals. Jesse, now living in the RV, puts his damaged house on the market. Skyler hosts a baby shower where Marie gifts her a diamond tiara. When Skyler attempts to return the expensive gift, store security detains her and reveals the tiara was stolen. Skyler confronts Marie about the theft, but Marie flatly denies stealing it, creating tension between the sisters. Walt and Jesse break into a chemical supply warehouse and steal a large barrel of methylamine, allowing them to produce meth through an alternative cooking process that doesn't require pseudoephedrine. They deliver four pounds of high-quality product to Tuco and his associates No-Doze and Gonzo at their meeting location. When No-Doze makes a casual comment during the transaction, Tuco flies into a violent rage and brutally beats his own associate in front of the horrified Walt and Jesse. Tuco then drives away, leaving Walt and Jesse shaken by the unpredictable violence of their new business partner.
