Theory:Doctor Who television discontinuity and plot holes/The Macra Terror


 * When Medok is called to provide the Doctor's alibi, the Doctor tells the Pilot not to believe everything that Medok is going to say.
 * Perhaps because he expects Medok to lie and try and get the Doctor into trouble.


 * How the atmospherically challenged Macra could take control (even with the charming voice one seems to possess) is never explained.
 * It obviously happened a long time before the story begins, and they are obviously an intelligent race. Many possible scenarios exist.


 * Scenes such as the Macra standing around the old Pilot, threatening him and pushing a microphone in his face, are hard to imagine.
 * Not really... They can hold a microphone easily enough, and have no trouble being threatening.
