After Officer Stevens and Officer Brooks tell Zach the penalty of filing a police report, Gale reprimands Zach and sends him home. Before she leaves to chaperone the school dance, Gale calls Lorraine over to watch Zach.
At first. She didn't believe Zach about the monster invasion. But she finally does when a Giant Praying Mantis grabs one of the attendees and she helps barricade the school. When Stine blows the monsters up with the bus, she cheers and hopes Zach will be careful, then replies, "not a good time" when Coach Carr begins flirting with her.
Following the aftermath of the monster attack, she is seen arriving at school with Zach.
- In the novelization, Zack reveals (after snapping from Gale not believing him) that the REAL reason she forced them to move to Madison is because she couldn't stand to live in her home in New York was because her husband, a fire fighter, had died in a fire.
