Mrs. Mitchell was a P.E. teacher at Hollyoaks Comprehensive School. In September 2001, the class prepared for a swimming lesson. However, Lisa Hunter refused to get changed - fearing that her wounds from self-harming would expose her - and locked herself in the bathroom. Lisa's friend Abby Davies warned Lisa that Mrs. Mitchell was enraged, resulting in Mrs. Mitchell finding the pair in the bathroom. Attempting to confront Lisa, Lisa ran off.
