Biography
Scott McCall, Stiles Stilinski, Kira Yukimura, Lydia Martin and Malia Tate traveled to Mexico in search of their missing friend, Derek Hale. Believing that he had been abducted by the Calavera cartel, they infiltrated one of the cartel's night clubs and attempted to bribe her with $50,000 American dollars for Derek's freedom. Araya communicated with Severo over walkie talkie, who told her that one of the club's guards had been knocked out.

At Araya's instruction, Severo then flooded the entire nightclub with an aerosol form of Wolfsbane, driving Scott out into the open and incapacitating him. Araya had Scott hooked up to a machine that sent electrical currents into his body, and forced his girlfriend, Kira, to administer the shocks. Severo held tightly onto Kira, making sure that she operated the controls as commanded.
