Theory:Doctor Who television discontinuity and plot holes/The Mind of Evil


 * The Doctor fears Koquillion and War Machines yet in their featured episodes, he had no or little fear of them.
 * There is a difference between not showing fear, and not feeling it on some level.


 * The destruction of the 'deadly' Thunderbolt missile at the climax of this story seems to do surprisingly little damage to the surrounding area.
 * Destruction of the missile itself doesn't automatically mean detonation of the payload, especially with nuclear missiles. At any rate, Thunderbolt has a poison gas warhead, and a nuclear-powered rocket engine. The explosive contents of the actual warhead / detonator are not mentioned, but presumably they are only sufficient to ensure widespread distribution of the poison gas and not massive ground-level destruction (Indeed, it sounds like a weapon designed to kill people and leave buildings and property mainly unharmed).


 * How does the water get into the drowned man's lungs if he's only killed by his fear of drowning.
 * The fears are physically manifested as well, as explained in the story.


 * During a fight sequence in which water is spilled, the Master twice slips in the puddle.
 * This may have been intentional on the actor's part.
 * How would it be a plot hole that someone would slip on a wet floor? Seems perfectly normal.
