Theory:Doctor Who television discontinuity and plot holes/The Myth Makers


 * Would the Doctor really have assisted in the sacking of Troy, even if his life depended on it, when he knew it would lead to the mass slaughter of hundreds of innocent men, women and children? This seems most out of character. I could understand his not acting to prevent it, in the interests of preserving the flow of History, but not actively engineering the destruction of a whole city to take place.
 * The Doctor doesn't appear to expect the wooden horse to work. He even laughs at the idea when Steven suggested it to him. He probably meant to use it as a stalling tactic while he tries to find a way to the TARDIS. When he realises it is going to work, he's horrified and tries to leave, which would tip the Trojans off. Odysseus has to hold him at sword point to stop him doing so.
