Allen is almost just as sociopathic as Kevin is, with his interests being smoking, drinking - as well as criminal activity. Allen often encourages Kevin's sociopathic behavior, usually asking him to do illegal, indecent, and/or dangerous things simply for the sake of the thrill, or for vengeance. However, Kevin, being a sociopath, often shows ambivalence towards Allen, sometimes threatening or intimidating the bird. During such times, Allen often reminds Kevin of the futility of these outbursts, since Kevin is simply imagining Allen's existence, and that no real harm can be done to the imaginary goose.
