She is located on the Stadium field along with Ryan Taylor, another nurse. She is grateful to be alive and unharmed. She was on the 4th floor of the hospital when the zombies burst in. She believes that she shouldn't have made it, and that she tried to help as many people as she could, but not everyone was able to escape.
She has the same name as Anna Williams, a character in the Tekken fighting game series. Ironically, her blond ponytail is more reminiscent of Anna's sister and bitter arch-enemy, Nina Williams. It should also be noted that their personalities and character roles are opposite: the Union City Anna Williams is a nurse who assists and saves people who are in need, while the Williams' sisters in Tekken are both assassins, and murder people for a career.
