Theory:Doctor Who television discontinuity and plot holes/Survival


 * Why doesn't the Master, as much a Cheetah Person as Ace was, just teleport off the planet?
 * The Master doesn't realise that to use the teleportation powers does not necessarily mean becoming a full Cheetah Person.
 * It is equally possible that the Master has never had a place that he truly considers home.
 * Further to this point, since the closest thing he has to a true home is Gallifrey, where his life is almost certainly forfeit (after the treasonous incidents of his last two visits), he may have deemed it marginally safer to remain on the Cheetah world until he could effect a less suicidal escape route.
