Mindy and Debbie Willett are cowering in fear in the storeroom of a woman's clothing shop as Paul threatens them with a Molotov Cocktail. Debbie pleads for him to stop, saying that they never did anything to him, but Paul accuses her of laughing at him. When Frank approaches them, Paul warns him to stay back or he'll burn the place down.
After Paul is defeated, Frank rescues Debbie and Mindy from the storeroom and offers to bring them to the Security Room.
Viewed from her dialog options, she appears to be one of the calmest people in the game: she forgives Paul for threatening her life, doesn't mind the zombies, and runs through hordes of zombies with a smile on her face.
