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


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


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


 * If it's 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 he got his Dad round.
 * Also, you know how Dads are! Sometimes all it takes is a casual mention of having a problem with a lightbulb and Dad will be there in an instant to take care of it.


 * In this story Nefertiti 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.
 * Actually, Akhenaton (Amenhotep IV) isn't known to have had consorts. Nefertiti was devoted to him, and there is some evidence to suggest that she was his co-regent at one point. However, as religion and not romance was his main focus, I'm all right with a little licence with history for the purposes of this tale.


 * 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.
 * Actually, it states it's been around for two thousand years, presumably they were quite old when Solomon bought them, thus explaining their odd mannerisms and their reported knock down price.
