Theory:Doctor Who television discontinuity and plot holes/The Androids of Tara


 * Romana's restraints look pretty easy to escape from.
 * Assuming, as seems likely, they were designed to restrain malfunctioning androids, they need only be secure enough to resist uncoordinated flailing as opposed to deliberate escape attempts.


 * Why does the prince have such a tiny number of troops at his disposal?
 * Because the population as a whole was diminished by plague, which is why the androids were introduced in the first place.
