As Michonne and her pet walkers trudge through the wilderness, Aiden and an injured Bailey suddenly emerge from the trees, startled to see Michonne. They cower in uncertainty and fear at first but Aiden pleads for help from Michonne, indicating they need to re-group with their caravan seen in the distance. She states that they need help and the caravan won't wait for them, to which Michonne agrees. After dispatching of her pet walkers, she assists Aiden and the injured man and begin the trek to meet up with caravan.
