Theory:Doctor Who prose discontinuity and plot holes/The Dark Path


 * How did neither the Doctor not The Master know that Ailla was a Time Lord?
 * If the Master suffers at the hands of Chronovores here, why is he so ignorant of the, in The Time Monster(set later)?
 * In Terror of the Autons, the Master is clearly coming to seek revenge on the Doctor, yet the Doctor is not even the one responsible for the Master's problems at the end of The Dark Path.
 * Multiple stories and interviews stress the significance of the Doctor and the Master being the only two offworld Time Lords at this time, yet the Doctor has no idea who this mysterious stranger calling himself 'Koschei' is.
 * To say nothing of Ailla.
