As a real estate agent shows Jesse's house to a couple, Walt arrives to find Jesse in his RV, still badly injured from the beating Tuco gave him. Walt gives Jesse his half of the money he took from Tuco. Walt and Jesse meet with Tuco and his henchman at a remote junkyard to deliver slightly less than the meth they promised. This does not make Tuco happy. After Skyler's baby shower, Walt recommends he try an alternative approach to his illness and visit a Navajo sweat lodge - a cover he uses to meet Tuco. The next day, Jesse brings all but one of the supplies needed to cook their next batch of meth. The last ingredient is very hard to come by, but instead of hiring pros to steal it for a $10,000 fee, Walt and Jesse steal it themselves - an entire barrel full. With the new ingredient, Walt and Jesse have developed a purer quality of meth. They again meet up with Tuco to deliver the new and improved product. Tuco is suspicious early on, as he has never seen product of this quality before. When one of his henchmen presumably speaks out of turn, Tuco goes ballistic and viciously attacks him, eventually killing him. Walt and Jesse look on in shock, as Tuco laughs it off, telling them he'll see them next week.
