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


 * The clothes found in a box in the farmhouse fit the travellers perfectly.
 * There may have been many more, unseen, outfits of different sizes elsewhere in the farmhouse that the travellers do not mention. Furthermore, if this is a safe-house, then clothing of various sizes to dress people that have been helped to escape is a very prudent consideration.


 * The dying Webster tells Ian of 'Le Chien Oris' and Jules Renan, but he remembers him talking of 'The Sinking Ship' and Barrass.
 * We didn't hear the entire conversation Ian had with the dying man, obviously.


 * Renan has made a rule that the escape line works on first name only terms, yet he knows two of the people on it as Rouvray and D' Argenson.
 * It may be Renan's personal rule (desire) but he can't prevent others from sharing their surnames if they want to.


 * The involvement of Robespierre and Napoleon in this story is historically inaccurate.
 * Both Robespierre and Napoleon were in France in 1794


 * The physician Susan is taken to after falling ill doesn't seem to notice Time Lord anatomy differences.
 * He does act suspicious of them, but that seems to be purely about what side of the conflict they're on.
 * Do we know for certain that Susan is a Time Lord? Is she really the Doctor's grandaughter? He might have adopted her when her family was killed, and called her his grandaughter to avoid suspicion. (That would explain why he was willing to leave Susan on Earth at the end of The Dalek Invasion of Earth.) Even if she is his blood-grandaughter, she could be as little as 1/4 Time Lord.
 * Without mentioning works that came after the episode in question, in "The Sensorites" she describes "Her home planet" [Gallifrey, but it wasn't named that yet] and she has telepathic abilities, which are implied to be common on her home planet. Then again, the Doctor calls himself human in that story, but that doesn't change the fact that that term is used VERY loosely by him and other Time Lords. There are many places that specifically state or at least imply that she was a Time Lord. As for the Doctor leaving her behind at the end of The Dalek Invasion of Earth, we can't expect him to have the same concept of family and emotions as an ordinary human being because he's an alien, all of his incarnations have acted strange like that at some point. Not to mention, since that story came after this one, we can't use evidence from it to explain something in this story.


 * Getting back to the original point - medical science and capability weren't at the same level then as they are today. They may not have noticed any anatomy differences, or simply chalked them up to her being ill (double heart beat being interpreted as a flutter, temperature indicating a fever/chill, etc).


 * The sign the Doctor sits on reads "Paris 5 km". The meter wasn't formally defined until 1799 and the kilometre wouldn't enter common parlance in France until far later. The more common term was myriametre and even that wasn't common at this time.
