Nothing is known about Ellen's life prior to or as the outbreak began. It's possible she had prior prep do to the fact she taught survival courses.
Ellen is described by June as a survivalist who taught her a few things during her stay at the FEMA settlement. However, it was revealed Ellen was bitten and succumbed to her injuries, eventually reanimating. She died inside a Land Rover vehicle at the settlement and was put down by June as Madison distracted her.
- Killed By
June left her sick daughter, Rose, behind so she could go get antibiotics to treat her. June didn't tell anybody about Rose. She turned and soon infected the whole group of survivors along with Ellen.
After finding the complex overrun, June discovers a zombified Ellen in a car and stabs her in the head with the help of Madison.
