Crosby meets with Ash's gang when Lem turns into a deadite after their encounter at a diner. Ash asks for Crosby's help and for some weapons and ammunition. Crosby and his people are suspicious of Ash and they refuse to aid him. Instead, they lock him and Amanda in their bunker and leave Pablo and Kelly hostage until they decide what to do with them. Deadite Lem attacks his former friends, killing a few of them. The attack gives enough time to Pablo and Kelly to escape Crosby's grasps.
When Ash and Amanda deal with the zombified Lem, they turn their fortune around and capture Crosby and what's left of his followers. They pack a bunch of weapons, but they are suddenly attacked by one of the deceased militia guy. Ash and his posse dispatch the monster right in front of Crosby's eyes, making him finally understand what's going on.
After released, Ash lets Crosby go and tells him that they should prepare for what's coming ahead. The two gang part ways with Crosby now believing that the evil has been released into the world.
