- "She's awake."
- —Winnie alerting Jocelyn as Michonne is awake.[src]
Nothing is known about Winnie's life prior to or as the outbreak began.
In a flashback, Winnie, Jocelyn, and Mitchell are found by a group from Alexandria in the woods and are brought to the community. Michonne recognizes Jocelyn as her friend from college and decides to let her group stay.
A while later, Jocelyn runs from the infirmary panicking and tells Michonne she needs to get back to “them.” Michonne calms her down and offers help. Later, Michonne and a group follow Winnie to a factory where they find several kids hiding out and bring them to Alexandria.
At night, Winnie and the rest of Jocelyn's kid group enjoys a bonfire with the community kids. In the middle of the night, Jocelyn and her group kidnap Judith and other children, kill a resident, and leave with the food supply and guns.
The next day, Michonne and Daryl spot P.J. outside of an abandoned school. They chase him until they're met by all of the kids in a hallway. Daryl gets shot in the shoulder with an arrow while Linus knocks Michonne unconscious.
Sometime later, they wake up bloodied and tied to a pipe. Linus painfully brands an iron X on Daryl and Jocelyn tells Michonne the kids can't be soft. Winnie then brands Michonne as she shrieks in pain. However, Michonne and Daryl manage to get free.
Michonne finds an exit and is immediately beaten over and over with a wooden plank by Jocelyn. Michonne summons the strength to stab her in her leg and the chest, killing her. Michonne gets up and tells the kids they can all return to Alexandria, but Mitchell instructs the kids to kill the Alexandrians as he deals with her. She's forced to kill him as the other kids close in. Michonne begs the kids to stop but they all attack her and she's forced to kill them one by one until Winnie remains. She cries at the sight of her dead friends and then runs away.
Her ultimate location and fate remain unknown.
