Theory:Doctor Who television discontinuity and plot holes/Time-Flight


 * As the Doctor correctly indicates, landing some 140 million years ago puts them towards the end of the Jurassic Period. However, he then says that they can't be 'far off' the Pleistocene 'era' (should be Pleistocene epoch), which wouldn't actually occur for another 138 million years.
 * He must surely have meant the Cretaceous Period, and the 'nip in the air' therefore cannot be the indication of an approaching Ice Age.
 * "Far off" is a relative term - assuming he wasn't simply being flip, as he often is.
 * Pleistocene "era" and Pleistocene "epoch" are both correct terminology, and are commonly used by the scientific community.


 * Why does the Master bother to dress-up and pretend to be Kalid? He surely can't be expecting the Doctor. What purpose can it serve, especially when dropping the pretense seems to have such little effect on his plans?
 * Possibly for the same reason (or lack of) he chooses to put on silly accents in "The Time Monster" and "The King's Demons". As a "master of disguise" (at least in his own estimation), not to mention as a wanted criminal, he prefers not to flaunt his real identity whenever it is avoidable
 * The Master is expecting the Doctor. A line in part 3 from the Master to the Doctor saying he had fallen into his trap.


 * A bird flies in front of Concorde when it takes off from Jurassic England.
 * There were birds in the Jurassic Period, particularly in the Late Jurassic Epoch.


 * Angela Clifford vanishes halfway through the story
 * The Master didn't need quite so many people anymore. Let's hope he didn't have the TCE handy at the time.


 * Assuming that the various apparitions Nyssa and Tegan encounter are the Master's doing, how exactly would he have known about their encounter with the Terileptils or Adric's death?
