- "What is it, Coop?"
- —Mrs. Twomey to Cooper[src]
Nothing is known about Mrs. Twomey's life before the outbreak began, except that she was married and had a daughter named Erin.
Mrs. Twomey is standing with Erin and other horrified residents as they watch the Browns' cabin burn. She begins sobbing after realizing that Martha and Russell must be dead.
Mrs. Twomey and her daughter are present at the front gate with the other townspeople when the Black Hat Natives arrive to move onto the ranch. At night, Mrs. Twomey is in her camper with her daughter when Cooper and Klah knock on the door, asking for any weapons being stored inside.
Mrs. Twomey is in line with Erin waiting for water from the main well when Ofelia offers Erin a glass of water, to which she knocks it to the ground. Mrs. Twomey brings an upset Erin closer to her and tells her that "it will be okay, sweetie". The next day, Mrs. Twomey and her daughter are talking to Alicia at the well when a fight breaks out. As Nick makes a stand and refuses to back down from the well, Erin joins Nick in his stand, followed by her mother and Blake Sarno. Mrs. Twomey and the other ranchers refuse to back down from the well and successfully drive the Natives away. As the crowd disperses, Mrs. Twomey continues to hold her child out of concern.
While her daughter Erin is seen safe in the underground pantry, Mrs. Twomey is no where to be seen, suggesting she was one of the many people killed when the horde of zombies broke through the RV wall.
- Killed By
- Troy Otto (Caused)
Troy secretly redirects a massive horde of walkers towards the ranch.
When the horde gets to the ranch and attack everyone, Mrs. Twomey is among those devoured by walkers.
This list shows the victims Mrs. Twomey has killed:
- Possibly numerous counts of zombies
- In "The Diviner", during the scene where the ranchers and Natives clash at the well, when Lee fires a warning shot in the air and everyone turns to look at him, the actresses who portray Erin and Mrs. Twomey can be seen running in the background towards their mark on set for the next shot in the scene, where they stand by Nick’s side in protest.
