Bethany Breen is the lab partner of Greg. While they're dissecting frogs, Greg feels disgusted and does not help her, as well as staying a safe distance from the dissection. Greg also once considered asking her to got to the school dance with him, but remembered the frog thing and decided against it. She only appeared in The Third Wheel.
