He had stolen my TARDIS, even. And Tegan and I were taken to where he had put it while Turlough saw Lord Geoffrey off. They were planning to kill us more than likely, Tegan certainly thought so. I told her that co-ordinates were set within the TARDIS, so she just needed to get in and get it going.
She managed that beautifully. Making the TARDIS demateralize distracted them enough so that I could escape and try to find the false king.
