Allie is a committed and capable teacher. Passionate about art, she’s the kind of cool teacher the students can relate to. Allie and Vaughan met as teachers at their last school. They began an affair, which led to Vaughan leaving his wife and sons to be with Allie. She’s very close to her children Floyd and Tiffany, and the move to Waterloo Road is a new start for all of them. Her relationship with Vaughan soon comes under strain from the amount of resentment and bitterness felt by his eldest son, Justin.

Justin’s fling with Tiffany ultimately ended with Allie and her kids moving away from Waterloo Road to start a new life elsewhere.
