Chase is first introduced on a rooftop, lying unconscious against a wall. He is awakened a minute later by Harris, who hands Chase a crowbar as a weapon. Across the way, a storage facility is seen and Harris suggests heading for it to collect supplies. Down on the street, Chase spots a picture of children and Harris is attacked and devoured by walkers, while Chase manages to break down the facility's door and enter the building. Chase then darts into a storage unit and attempts to lower the shutters, but some walkers manage to reach underneath them. Suddenly, all three walkers are shot dead by an unseen person in the corridor.

Chase is being chased by walkers and runs to a storage locker. He enters the locker and attempts to close it. On the other side of the storage door, Chase hears gunshots from a man named B.J., who killed all the walkers chasing him. B.J. tells Chase to leave the storage locker and show himself. After, B.J. tells Chase to leave the facility. B.J. is questioned by Chase, and Chase says he'll power up the generators, in return for powering up the generators, Chase would get a truck. While walking to B.J.'s office, he is told to look through a storage room that was owned by a cop. It is revealed that the cop is Rick Grimes. Chase finds pictures of Rick's family and smiles upon looking at them before grabbing a new shirt and heading to the office.

Chase enters B.J.'s office and B.J. orders Chase to head up to the next floor to turn on the power. Chase walks upstairs with a crowbar and reaches the generator area. While figuring out the generator's controls, a walker, Lenny, roams up behind him and Chase accidentally kills it. He then returns to B.J., who informs him of the walker's identity, a former co-worker of his. Chase goes outside with him, only to be betrayed and shot by B.J.

Chase was only grazed and survives the gunshot and slowly makes his way around the facility. While walking to a door to enter the facility, he encounters a zombified Harris. Chase smashes Harris' head in with a cinder block and takes his machete. Chase manages to break a lock and enters the facility. While up there he enters a room full of furniture with a lone woman named Kelly being held against her will. She screams, but Chase reassures her that he is a good person. After that, the two begin to escape the facility knowing B.J.'s dark secret.
