Nothing is known about her life before the outbreak started, other than she lived with her father and brother.
At some point after the apocalypse her father sacrificed himself so that she and her brother could escape. After meeting Negan she panicked in a Walmart which resulted in her brother getting killed. At some point either before or after her brother's death she got bitten on the neck but didn't realize it, which pissed off Negan due to her being "weak". Ultimately he decides to leave her to die and reanimate in the car park,
- Killed By
- Zombies (Alive)
While in a Walmart she got bitten on the neck without realizing it. After showing her bite to Negan, he got angry and left her to reanimate in the car park, because he saw her as weak.
This list shows the victim this survivor has killed:
- "I can still hear his screams."
- —The sister recalling her father's death.[src]
She and her brother presumably had a good relationship.
- "You're bit?! FUCK YOU! Go fucking fuck yourself up your fucking ass, you fuck. I'm sick to death of this shit! You ran and let your father die. You fucking flipped your shit in there... and let your fucking brother die, and for all your trouble... you get to fucking die. I'm sick of you people. You're all fucking weak. All you ever do is die. So go die."
- —Negan to the Sister.[src]
