- "So, if you don't remember, I'm Bertie. And I owe my life to you all, twice over. A bunch of us do. Enid says that you want Gregory to get us to fight the Saviors with you. Is that true? (...) Do you think we can win, that we really could beat them? Us? (...) Well, Enid says you could show us the way. I'm ready."

Bertie is a survivor of the outbreak in AMC's The Walking Dead. She is a resident and former supply runner of the Hilltop Colony. Following the end of the war, Bertie became a teacher for the children at the Hilltop.
Nothing is known about Bertie's life prior to or as the outbreak began.
Bertie became a resident of the Hilltop Colony at an undisclosed point before this episode. She traveled on a supply run with Freddie, Carson, and Wesley to scavenge supplies, most importantly medical supplies. Their car crashed on the way due to Walkers, and the four hid inside a nearby house from the dead. She and Wesley were subsequently rescued when Rick and his group arrived to rescue her group on behalf of Jesus, after-which she alerted her rescuers to the fact that two of her members were still in the building, one of them being hurt. She joined the group in the RV on the ride back to Hilltop and entered with the group once they got there. She later cleans her boots as she sits on a set of steps when Dr. Carson approaches her.
Bertie is among the Hilltop townspeople to gather in front of the Barrington House and pledge allegiance to Rick and his crew, thanks to the recent efforts of Maggie and Sasha, who saved the town from a zombie attack that was started by the Saviors.
Bertie, alongside Freddie, Eduardo, and other Hilltop members, train in hand to hand combat with Maggie, Sasha, and Enid. Later, Bertie is outside with Freddie as the Saviors take Dr. Carson away to the Sanctuary.
Just as the Kingdom regiment arrived in Alexandria and began attacking the Saviors, Bertie and her fellow Hilltop militia join the fight. Bertie yells orders to the militia as the Alexandrians are liberated and everyone fights back against the Saviors and Scavengers. As she and the others clear the streets of hostiles, Maggie orders Bertie and Eduardo to cover the houses as they perform a final sweep, giving chase to the fleeing Saviors. They open fire as Negan and his surviving soldiers drive away in their trucks. She is unsuccessful in opening the gate so the militia can chase after the Saviors, unaware that the gate was jammed with a red umbrella.
Later, Bertie is present for the leaders' speech and listens to Rick, Maggie, and Ezekiel as they address the crowd of Alexandrians, Hilltoppers, and Kingdommers. She listens with a focused look of determination on her face as she is encouraged to unite with her fellow survivors and communities to fight back against the Saviors.
Bertie and her fellow residents help secure sheet metal onto multiple vehicles at the Hilltop. The next day, she speaks with Maggie as other prepares for an upcoming assault. She is among the militia to listen to the leaders' speeches before they launch their assault on the Sanctuary. She listens on to Gregory's attempt to dissuade the Hilltoppers from attacking the Saviors but ignores his demands. After successfully ambushing the Saviors' headquarters, she and the others leave in their vehicles so the incoming horde may swarm the factory. She is among those to accompany Maggie back to the Hilltop.
Though unseen, Bertie is in the last car of the Hilltop convoy heading to the Kingdom when they are stopped by a tree in the road. Maggie, sensing something is not right, radios Bertie to turn her car around so the convoy can head back home, but the Saviors arrive and prevent them from doing so.
Bertie works alongside other Hilltoppers and Kingdommers as they help with improving the town's defenses. At one point, she conducts an inventory of the Hilltop's rations with Dianne and conclude that they will have to reduce rations by a third to survive the week. After the arrival of the Alexandrians, she gathers by some vehicles and chats with Nabila, Kevin, Barbara, and other Hilltoppers.
Bertie is among the lookouts who blares their horns to signal to the Hilltop that the Saviors are en route to the town. She, along with Rick, Daryl, Jesus, and Scott, arrives at the Hilltop during the battle to provide cover fire as they enter through the gates. After the Saviors are successfully driven away, Bertie rests in a room full of survivors, including an injured Bruce. At night, she remains in her room as zombified residents attack one another. When a zombified Tobin enters the room, Bertie is attacked but saved by Carol. When the survivors realize what killed their friends, a sick Bruce begs someone to put him out of his mercy.
Bertie remains behind in Hilltop with Eduardo, Kal, and other members of the militia to protect the town and the civilians hiding inside. When the Saviors arrive, Bertie helps evacuate everyone out of the settlement and into the woods for safety. She later returns back to the Hilltop in the aftermath of Oceanside's counterattack on the Saviors.
Bertie works inside the Barrington House as Tara makes her rounds collecting updates from the townsfolk on their projects.
In Hilltop, Bertie watches as the group arrives with Jesus' body and the captive girl, causing her to look in shock and sadness. Later, she listens as Tammy tells Tara that the Hilltop will now look to her for leadership, reminding her that includes getting justice for Jesus.
A while later, a funeral is held for Jesus and everyone take turns hammering the nails in his coffin. Bertie is present and looks in sadness.
