Nothing is known about Pat's life before the apocalypse except that she had two kids, Charlene and Dax, and was friends with the Otto and Trimbol families long enough to have Jeremiah hold the honor of godfather to Pat's daughter.
Pat is at the memorial service for her daughter and she says a few words about Charlene while holding back her tears. The next morning, she is having breakfast with Vernon as Jeremiah informs the crowd about the missing search party.
Pat and her son Dax attempt to remove supplies from the armory and are stopped by Troy. She informs Troy that Jeremiah gave her permission to remove what's hers as she plans to leave the ranch with her son. After learning that the Trimbol family was slaughtered, she decides to stay on the ranch and returns the supplies to the armory.
At night, Pat is with a group of ranch residents, including Bob, in Jake's house complaining about the rationing of the water, stating that her horses and cattle need at least 5 gallons of water a day. When Alicia interrupts the angry residents, she is able to calm them down by reminding them that Jake is trying to keep the peace despite losing his father and brother. Pat calms down and hugs Jake in gratitude for all he has done.
Pat is among the ranchers to evacuate to the underground pantry. As Alicia addresses the crowd regarding those bitten, Dax stands up to sacrifice himself and Pat cries out. Later, Pat is among the survivors to pass out due to the lack of air and eventually dies or is killed by the reanimated residents. Shortly after her death, she reanimates and proceeds to gnaw on Alicia's boot as she is passed out. When Alicia wakes up, she kicks Pat away and proceeds to stab her in the head.
- Troy Otto (Caused)
Troy secretly redirects a massive horde of walkers towards the ranch. When the horde gets to the ranch and attack everyone, the remaining survivors enter the pantry.
- Suffocation (Alive, Caused)
Due to the lack of air, several survivors suffocate, among them Pat.
- Alicia Clark (Zombified)
Later, a zombified Pat attempts to bite a dazed Alicia, but is stabbed in the head.
This list shows the victims Pat has killed:
- 1 unnamed Broke Jaw Ranch resident (Infected)
- Possibly numerous counts of zombies
