Theory:Doctor Who television discontinuity and plot holes/Dinosaurs on a Spaceship


 * At the end Nefferteti stays with Riddle, but doesn't that change history?
 * Not necessarily - The actual Nefertiti disappeared from the historical record, making this a historical in-joke.


 * How does Riddle, who is from early twenth Century Africa know about Anestetic?
 * Anaesthetic was invented long before the twentieth century. Incidentally, it's doubtful he's from Africa, but England instead, where Anesthetic was known from the 1700's.


 * If its just to change a bulb, why ask Brian to come round?
 * As implied by dialogue in the episode, it wasn't the light bulb that was the problem but the fitting. Rory couldn't work it out initially so got his Dad round.


 * In this story Neferteti hates her husband, but in actual history, the two were quite close.
 * she was bored by him (after over 14 years of marriage); this doesn't necessarily mean she hated him. He also had other consorts.


 * At one point, one of Solomon's robots comments that they've been on the ark for two thousand years. But they came there with Solomon, and he doesn't seem to have been there very long.
