She wouldn’t listen to the Doctor’s protests to stop doing the ghost shifts. However after a while she heeded the Doctor’s warning and delayed the next ghost shift. However some of her staff did it anyway and more Cybermen who capture her, the Doctor, and Jackie. The Cybermen then activate more ghost shifts, causing nearly 5 million Cybermen to come to Earth.
