Steven (left) follows Alfredo into the diner
Steven is the silent muscle to Alfredo's explanatory enforcer, part of the duo who accost Guerrero when first we see him, and attempt to make him aware of the error of his ways in sniffing around Soucha's Bank. Although neither of them introduce themselves, Guerrero displays a knowledge of their identities, as well as peripheral information, such as Steven's marriage to Marla and the fact he has daughters, which backs up his claim that "Your employer keeps sensitive information on a drive he thinks is secure. It isn't.". Steven flees in the wake of Alfredo when Guerrero's true colors come out, and tips his hand concerning his potential plans for murdering both of them. ("Pilot")
