Murphy's Miracle

S3, E4: While on the road to establish his headquarters in Spokane, Murphy saves the life of a dying girl. When her parents show up in Spokane and ask to be bitten too, Murphy's mission gains momentum. Elsewhere in the Apocalypse, Warren and the others follow a survivor named Wally toward supplies. Wally's town is completely zombified, but for some reason these zombies are solely interested in Wally.
