1x4 - The Walking Dead: Torn Apart

Andrew travels to his neighbour's (Palmer) basement in search of guns and supplies. Palmer asks Andrew why he needs his gun, and Andrew mentions his dog, Max, who has been torn up by the walkers. Palmer tells Andrew he's got more of a problem than his dog and then reveals his wounded leg. Andrew insists that Palmer should go to a hospital, but Palmer mentions that the CDC is searching for a cure and claims that the outbreak was organized by terrorists. He tells him how he had to kill his wife, Maggie. Palmer then explains to Andrew how to operate the shotgun and hands him the weapon as he helps Andrew point the gun at his own head.
