Her father was Tony Mack, one of the two onsite executives of the Cwmtaff drilling project. (TV: The Hungry Earth) She was mocked by the captured Silurian, Alaya and unintentionally killed her. She helped her father and Rory Williams carry the body down into the Silurian city, where she confronted the Silurians and angered them except for Eldane who was more forgiving than Restac.
