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?
 * It's highly unlikely that the writer simply 'forgot' about this, so it could be part of a story arc, with the answer revealed later on.
 * Or the explanation was cut, the end of the episode is rather rushed...
 * How did the doctor know at what point exactly Hila was going to appear?
 * He guessed


 * 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?
 * They do


 * Where did the doctor get a Metebelisis III Crystal from, weren't they all destroyed at the end of Planet of the Spiders?
 * He may have got one from another encounter with the Eight Legs
 * But they were all destroyed when the great ones chamber exploded.
 * Are we forgetting time travel? the doctor simply has to go to an earlier period in time than when they were destroyed.


 * 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.
 * The mate may have been dislodged when Hilda crashed


 * If the Crooked Man only wanted his mate, why all the sinister laughter? Is that really the only way it can communicate?
 * Maybe the Crooked Man was running from something else that made the laughter
 * it was likely to be how the species communicates and only sounded like laughter.


 * Metebelisis II Crystals are used her very differently than they were in The Green Death and Planet of the Spiders, they still enhance mental powers and such, but before they did so with rewriting the brain, not being used to broadcast the abilities.
 * The Doctor is using it alongside other equiptment.


 * Why has the Doctor forgotten how to pronounce Metebelisis III?
 * It's been several Regenerations since he's pronounced Metebelis


 * How exactly does Hila write the message on the wall? She has not crossed through just yet. And why does it suddenly disappear?
 * Maybe it was written by the Crooked Man?
 * it was written is frost so it simply melted. how it was written, is a different matter.
