Todd Alquist

Todd Alquist (played by Jesse Plemons), is an exterminator for Vamonos Pest, a fumigation company used by Walt, Mike, and Jesse as the front to their meth business after Gus Fring's death. Todd and the other Vamonos employees are burglars, gathering information and selling it to outside parties from the houses they tent, though this practice stops once they conceal the meth operation. Todd notices and disables a nanny cam at Walt and Jesse's first cook site, attracting their attention. He is later used as an accomplice in the heist of methylamine from a freight train. The heist is successful, though Todd shoots and kills a young boy named Drew Sharp, who stumbled upon the crime. Todd does not show much remorse about the murder; he explains to Jesse that "shit happens" and keeps the boy's tarantula as a trophy. The team reluctantly keeps Todd employed after he explains his actions: there could be no witnesses, and his uncle, Jack, could be valuable to the operation. After Jesse and Mike exit the business, Todd becomes Walt's partner in the cooking process. Todd helps Walt dispose of Mike's car and body after Walt murders Mike, and Todd uses his uncle's prison connections to help Walt eliminate Gus Fring's nine former employees and their lawyer who were imprisoned. With no one opposing them, Walt and Todd partner with another meth distributor, Declan, and Madrigal Electromotive executive Lydia Rodarte-Quayle to run a highly profitable meth empire for months across the American Southwest and overseas in the Czech Republic, until Walt bows out of the business. This causes the purity of Lydia's product to fall to an unacceptable 68%, prompting her to (unsuccessfully) try to bring Walt back into the business and ultimately to hire Todd, his uncle, and the Aryan Brotherhood to massacre Declan and his men, in order to reinstate Todd as the primary cook. They then take the methylamine from Declan's lab and return to New Mexico.
