Theory:Doctor Who television discontinuity and plot holes/Hide


 * As the device that allowed Emma to break through into the pocket universe required the Tardis's power to function, thus the long extension cord from the Tardis, why does it keep working after it departs?
 * Exactly why was that specific spot cold? And why did the temperature drop so suddenly?
 * How did the doctor know at what point exactly Hila was going to appear?
 * Despite dropping to bellow zero, we don't see anyone's breath after the doctor leaves the spot.
 * Also if its so cold how come no one reacts to the sudden great change?
 * Where did the doctor get a Metebelisis III Crystal from, weren't they all destroyed at the end of Planet of the Spiders?
 * How did the Crooked Man's mate get trapped outside the pocket universe, the only doors were opened by Emma, and nothing got out of them.
