Giselle was the Programme Controller's secretary. She was secretly in charge of the whole Meson Broadcasting System station, manipulating events through its web of surveillance equipment. When Krllxk invaded the station, she sent Jak Martyn and some security guards to stop it. They failed and were killed. The station was evacuated and she went to her office to collect the blackmail data she had gathered to maintain her power. However, by the time she finished, all the escape pods had left. The Sixth Doctor, though, was able to use the Marston Sphere to transport her and the others still alive on the station to Torrok. With Anson Hammond, they were able to hold off the Watchers and the robot Peace Keepers until Grant Markham and Firn Kaerson deactivated the Peace Keepers. (PROSE: Time of Your Life)
