"The thing is, if you just do stuff, and nothing happens, what's it all mean? What's the point?"
- Jesse PinkmanJesse Bruce Pinkman is the deuteragonist of Breaking Bad. He is the former partner of Walter White in the methamphetamine drug trade. Jesse was a small-time methamphetamine user, manufacturer, and dealer. He was also an inattentive student in Walter White's chemistry class, leading to his dropping out. In his mid-20s, Jesse became Walt's business partner in the meth trade. Before his partnership with Walt, he, operating under the pseudonym "Cap'n Cook", added a little Chili Powder to make his methamphetamine stand out in the market.
Walt insisted on making a pure product, however, and thus eschewed the chili powder altogether, patronizingly teaching Jesse how to make "proper" meth. Walt often treated Jesse like a foolish son in constant need of stern correction. Jesse's own family kicked him out because of his drug use. Despite the friction between them, he and Walt have a deep bond of loyalty. Like Walt, Jesse is horrified by the brutality at the higher levels of the drug trade, but does what he thinks is necessary. He wrestles with feelings of guilt about the deaths, all drug-related, of people he's been associated with, especially his girlfriend Jane Margolis. He often attended Narcotics Anonymous meetings to help deal with these feelings.
Later on in the series, Jesse's loyalty to Walter becomes strained upon learning from Saul that Walt tricked him into helping him bring down Gustavo Fring by poisoning his girlfriend's son, Brock. As a result, he teams up with Hank Schrader, Walt's DEA brother-in-law, to bring Walt down. They were almost successful, but were stopped by Jack's White Supremacist Gang before Hank could make the arrest. After Hank was killed by Jack, Jesse was later taken prisoner by the gang and forced into labor as a meth-cook slave which he complied with for the sake of his ex-girlfriend Andrea and her son Brock, even though the former was killed when he tried to escape. During the final episode, Jesse was freed by Walt, leaving him mentally and emotionally broken from the events that occurred throughout the course of the series.
