Dave is a survivor who had been traveling around for an unspecified amount of time since the outbreak began with Tony,Randall, Sean, Nate, Jane, and around 30 other survivors. He served as the secondary antagonist of Season 2 (despite his very short time on the show) and the primary antagonist of the episode "Nebraska".
He and Tony arrived at Patton's Bar that Hershel, Rick, and Glenn had occupied, and commented on the fact that they were both still alive. Dave, the "people person" of the two, was seemingly thrilled to discover other survivors. However, Hershel and Rick instantly found the men untrustworthy when they mentioned the farm's existence when neither had mentioned it before, as well as Rick's natural instinct upon learning Dave's humor in stealing his pistol from a dead officer. An overzealous Glenn acknowledged the farm's existence until Rick stepped in and said that Dave and Tony would not be coming with them.
Dave once again attempted to earn the survivors' trust before the shoot-out, casually leaping over the bar and placing his gun on top of the counter while looking for better liquor. Upon withdrawing a bottle of whiskey, Rick rebuffed his inquiry of the farm once again before Tony gave away what was obviously an ambush. As Dave went for his gun, Rick whipped out his revolver and shot him in the head, killing him instantly before doing the same to Tony.
