Olivia Cormack is Nick's wife and a waitress at the A&G Diner. In contrast to her husband, she is kind and very helpful to the investigation. She appears uncomfortable at times and doesn't seem to have a close relationship with any other women in town. Despite all of the accusations surrounding Nick during the investigation, she stands by him and promises to wait for him to be released from jail.
- After Nick is arrested, the player can catch Olivia doing laps around her living room at home. She will even stop and touch her wedding photo, and seems so distressed that she will walk right up to the window and not notice York's face.
- Her trading card states that Olivia had a bit of a dark past. However, nothing comes up during the game to explain it.
- Nick and Olivia sleep in seperate bedrooms, even after his name is cleared.
