From the official site:
Mary (Deputy Head and Gene Simmons' Mentor)
Mary was asked to be Gene
Simmons' mentor, helping him to understand what was expected of him when teaching at Christ's Hospital. In return, she was invited to visit Los Angeles to gain a better appreciation of his rock star life style, attending the American Music Awards as his guest. She and the pupils somehow managed to fit this in on top of most of their normal school commitments.
