Mack is first seen with Addy and Doc buying weapons from traders Skeezy and Sketchy. He helps fight off a small wave of zombies attacking them and the traders. He is later present with Doc when the camp of the Upstate New York survivor group is found destroyed. Mack joins Garnett in finding the military convoy, finding it destroyed near a building. As he searches the surrounding area he encounters a pack of zombies surrounding a cage. After clearing away the zombies together with Doc and Addy, he breaks the lock and enters the cage to interact with the survivor inside. The survivor, Cassandra, pins him to the cage wall with a knife. She calms down after holding him there for several seconds. He joins the Westward-bound survivor group to California.
Mack leaves the group in Utah outside the Sisters of Mercy camp, where Addy is. He refuses to leave Addy behind and is then promptly shot at by Helen forcing him to get on the truck containing the Westward-bound survivor group. However unable to leave Addy he jumps off the truck as it leaves and several gunshots are heard.
He is seen at the end of the spisode looking up at the nukes in the sky.
While looking for Murphy, Mack and Addy gets separated. His attempt to escape was thwarted by a locked door and despite Addy's best efforts, she was far too late on saving Mack as he was caught by zombies and devoured just as she opened the door. His last moments as a human have him smiling despite being in pain. Addy tearfully shoots him in the head for a mercy kill.
