- "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? (...)

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 is later seen cleaning her boots as she sits on a set of steps when Dr. Carson approaches her.

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.
