Theory:Doctor Who television discontinuity and plot holes/The Curse of the Black Spot


 * Wouldn't the TARDIS translation circuit make Captain Avery understand what the Doctor meant by "sensors"?
 * If he doesn't know what they are, he still wouldn't understand what the Doctor meant. It's like how the people in Pompeii didn' t know what a volcano was.
 * If the crew on the alien spacecraft got a human disease then why didn't the 'Siren' put them in stasis as well instead of leaving them to die? Toby had a fever and he was put under stasis. Shouldn't the same apply?
