Theory:Doctor Who television discontinuity and plot holes/The Power of Three


 * If the Doctor, Rory and Amy were able to jump through the portal as it exploded, surely parts of the explosion itself would also travel through?
 * If the cubes could scan all information on people, then what was the point of kidnapping the humans?
 * Who were the aliens with large mouths and what happened to them?
 * In this story electricity effects the doctor like a human, but in several other stories (Terror of the Zygons, World War Three, A Christmas Invasion, The Pandoric Opens etc) he's shown an incredible resilence to electricity.
 * When removing the cubes from the hospital, no one seems to notice the little girl still has one.
 * Surely someone would have noticed the fact that the same girl was in the hospital for a year.
 * Why does no one notice the disappearing patients?
 * In this story having only one heart is impossible for a timelord to manage, but in the past he's survived with only one heart.
 * How does the visual aid recognise the doctor?
