Theory:Doctor Who television discontinuity and plot holes/Under the Lake


 * What did the crew do in the missing three days? Just run around like headless chickens getting supplies and finding somewhere to hide whilst dodging cutlery throwing ghosts? Not bother to contact the Main base?
 * It presumably took them some time to realize that they were safe where they were, and that the ghosts didn't come out during the day. That, along with gathering supplies, investigating what was going on, occasional sleep, etc, probably accounts for the time.


 * I'm a little confused! The base is now underwater. I assume that the "city" was somehow flooded, and because it was flooded, there was no use for the "city" and everyone was evacuated. So why does the base have a computerized day and night setting?
