Theory:Doctor Who television discontinuity and plot holes/Hide

You are exploring the Discontinuity Index, a place where any details or rumours about unreleased stories are forbidden.
Please discuss only those whole stories which have already been released, and obey our spoiler policy.

This page is for discussing the ways in which Hide doesn't fit well with other DWU narratives. You can also talk about the plot holes that render its own, internal narrative confusing.

Remember, this is a forum, so civil discussion is encouraged. However, please do not sign your posts. Also, keep all posts about the same continuity error under the same bullet point. You can add a new point by typing:

* This is point one.
::This is a counter-argument to point one.
:::This is a counter-argument to the counter-argument above
* This is point two.
::Explanation of point two.
::Further discussion and query of point two.

... and so on. 

• 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.
