Theory:Doctor Who television discontinuity and plot holes/Nightmare in Silver
From Tardis Wiki, the free Doctor Who reference
- When the Doctor refers to using up his current regeneration and not knowing what his next life would be like, is this a reference to the Valeyard, and thus the 6th Doctor reference for this episode?
- When the Doctor bluffed that he is about to win the game in three or five moves, that would not require the Cybermen to invest a significant effort to verify. A 6-ply (three move pairs) look-forward in chess game does not involve that many different combinations even if they are checked using brute force. In fact, a typical desktop computer of today can do it in a few minutes, and I'd presume the Cyberman is more efficient than a today's computer. (Tested with: http://www.vanheusden.com/DeepBrutePos/ ) Also, they did not negotiate a time limit for the moves... A match with a computer is pretty much meaningless when the computer can spend an eternity thinking a move.
- Three million Cybermen hiberating/recuperating completely undetected? An empire that can destroy a galaxy will have routine detection equipment sensitive to detect such things before leasing a planet for commercial development.
- What was comical about Nanny Longshoe's Comical Castle?
- Why did the children sleep in the manniquin room rather than be kept safe in the tardis?
- Why did the emperor not evacuate and destroy the planet the first moment he became away of a cyber infestation?
