Theory:Doctor Who television discontinuity and plot holes/State of Decay


 * The Doctor says the Tower decor is rococo when actually it's late Saxon/early Romanesque.
 * It's technically not quite either style, depending on whether development in the appropriate period is part of your definition. This was decorated in the future on an alien planet. The Doctor is being glib, as he often does. Rococo can also refer to any style that one considers to be unnecessarily elaborate, which the Doctor might well consider this to be.


 * In the cliffhanger to part one there are hundreds if not thousands of bats - who seem to conveniently disappear before the reprise in episode 2.
 * Some bats can move quite quickly, and these may well have simply flown out of shot.
