Gracie is a survivor of the outbreak in AMC's The Walking Dead. She is the daughter of a Savior. After the death of her father and the end of the war between the Militia and the Saviors, she is adopted by Aaron and resides with him at the Alexandria Safe-Zone.
Gracie was born into the apocalypse, and lived with her father and the other Saviors for the 5 months prior to the war between the Militia and the Saviors. It's unknown what became of her mother but her father is known to have survived long enough to be able to take care of her for those 5 months.
After Rick kills Gracie's father in a scuffle, he enters her room expecting to see guns but instead finds a baby Gracie sleeping in her crib, causing him to break down in tears knowing he just left her without a father as well as thinking what would happen to Judith, his daughter, should he meet his death.
After the outpost she had been living in is cleared out, Rick brings Gracie outside to the other Alexandrians. He suggests that he can bring Gracie home but Aaron, distraught following the death of his boyfriend, offers to take her to the Hilltop Colony where she will be safe.
When the heartbroken Aaron is greeted by Maggie at the Hilltop, she sees that he is carrying Gracie in his arms. Later that day, Maggie holds the baby as she talks with Jesus about the captured Saviors.
As the days passed by, Gracie settled permanently in the Hilltop and began using a crib inside the Barrington house. When Maggie is informed about the supplies, she watches as Gracie plays around in her crib.
Early in the morning before the final battle against the Saviors, Rick watches over Gracie as Siddiq comes to take care of her. When the Saviors arrive, Gracie is escorted outside of Hilltop by Enid and the remaining Hilltopers. Due to her cries possibly catching attention, Tara along with Alden and the defected Saviors stay behind to attack the bandits.
Sometime after the war ends, Gracie is adopted by Aaron and she moves to Alexandria to live with him under his care where at first she was considered a challenge to him, especially when he had to change her diapers. Six years after Rick's assumed death, Gracie is now 8 years old and has grown to accept Aaron as her father, calling him "daddy". One morning as she plays with other children on the playground, Gracie gets happy to see her father return and runs over to him with excitement but Aaron tells Gracie to stay back as he deals with a group of strangers.
When Michonne goes to visit Aaron at his house, Gracie happily greets her at the door and then calls for her dad to come so he could talk with Michonne before going to play inside.
Gracie plays with Judith and R.J. on a bike in the street when Michonne comes out of her house and orders Judith to keep her brother safe as she goes over to the front gate.
In a flashback, a two-year-old Gracie sits in Eugene's lap, wearing a Jack-o-Lantern costume, during the Halloween bonfire with Jocelyn's group and other Alexandrians. One morning, as Michonne heads to pick up Judith from a sleepover, Gracie is out on a walk with Aaron around Alexandria.
Some months after the blizzard, Gracie is part of a class of young students trying to learn how to read. She is supportive of Lydia and tries to help her with some words, despite Lydia being frustrated by her failures. When the council enters the meeting room to discuss the threat of the Whisperers having returned, Gracie goes back home.
Gracie attends the funeral service for Siddiq and listens to Gabriel's religious remarks. She silently pays her respects and then leaves the ceremony with her father. Later that day, Gracie plays with Aaron a game where she has to guess the capitals of each state from the license plate mural he made with Eric years prior.
After winning, Gracie high fives her dad with her handmade fake prosthetic and asks for a story as her prize. She listens as Aaron says he once went hiking with a man he loved in Eureka, California. They stood in ancient ruins and listened to the sound of the ocean waves which were far away and wondered what life was like for the old civilization. She asks for the villagers' whereabouts but Aaron doesn't know what happened to them.
When Aaron returns back to Alexandria the next day after Beta's attack, he introduces Gracie to Mary. Afterwards, she leaves with her father and a group of Alexandrians and coalition soldiers in wagons towards Hilltop.
Gracie is among the children and parents to be evacuated from Hilltop. However, the caravan is prevented from reaching Oceanside after reaching a roadblock consisting of a fallen tree, the doings of the Whisperers. The caravan turns back to Hilltop, along with the bodies of murdered scouts Felix and Penny. Upon arriving at Hilltop, she runs into her father's arms. That night, she takes refuge inside Hilltop with the other children and civilians as the coalition soldiers fight against the Whisperers and their horde.
The Whisperers attack the Hilltop Colony with their horde and flaming arrows - setting fire to the Colony. Ezekiel began to lead the children out of Hilltop - including Gracie - but could not locate Judith. Earl Sutton was able to locate Judith and took charge of Gracie and the other children while Ezekiel fought at the Hilltop.
Earl brought Gracie and the other children to a safe-house in the woods awaiting for their parents while he continued to suffer from the bite from a walker on his arm. He refilled Gracie's water cup and told her that she was brave and her father would be proud of her. Gracie asked when Aaron and the other parents would arrive, and he answered soon.
Judith took care of Earl in the backroom while Ezekiel led Daryl and Jerry to the children and reunited.
