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?
 * An "aspect" of the Eye of Harmony remained attached, which presumably supplied the power. The cables from the TARDIS were likely just needed at the beginning.


 * 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...
 * The typical explanation for a drastic change in temperature in the psuedoscience of ghost hunting is a spirit attempting to drain energy, eg heat, batteries etc, from an area so that it might manifest physically.
 * How did the doctor know at what point exactly Hila was going to appear?
 * He guessed
 * Or, he likely calculated it.


 * 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 react.
 * No they mention it, and we do see the doctor and Clara react for a short while, but when the shot changes to Emma and the professor despite the temperature dropping bellow zero no one's shivering.
 * They can certainly feel cold without overtly reacting to it by shivering, etc.


 * 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.
 * Then how did they all turn up in the great ones lair?
 * Again, as a reminder, it's time travel. He can take the crystal, keep it from a thousand years, and return it back to the same moment he took it from. Hence, they can all be there by the time of Planet of the Spiders (which does take place in the far future as well).


 * 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
 * So its been in the same place for millions of years?
 * Or for a few minutes. Time is flowing at a different rate in that universe, so Hilda's arrival spanned a hundred thousand years.


 * 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.
 * As mentioned in the story, the Doctor believed that it was trying to make him (and Hilda) scared, so they would run - and, it assumed, head back to wherever its mate had disappeared to.


 * 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.
 * Lots of places and words have multiple pronunciations (data, tomato, etc). He's just using a different pronunciation now than he did all those centuries before.


 * 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.
 * Presumably the writing was also a manifestation or psychic interpretation of the message from Hila.
