Editing Theory:Doctor Who television discontinuity and plot holes/Robot

{{Discontinuity}}
*K1 with doll Sarah and Action Man tank. His legs keep vanishing as well. 
::Perception as the living metal changes size.

*The SRS goes to great lengths to get the disintegrater gun, and then all they use it for is to blow open a safe door. Couldn't they have found an easier way into the safe? 
::It is implied that high explosives would be the only other thing capable of opening the safe, and would carry the risk of destroying its contents. Presumably the disintegrater gun can be controlled well enough to only destroy the door. It also makes a nice weapon for them to have for later, should they need it.

*Miss Winters' feminist views (her comments to Sarah in episode one) don't accord with SRS views on women. 
::In what way? All the SRS man at the meeting hall says to Sarah-Jane is that she should not be allowed to wear trousers. This could well be a private view and may not explicitly be about women. Secondly, all Miss Winters says in episode one is that she wouldn't expect <u>Sarah Jane</u> to make a stereotypical assumption about who was running the think-tank, not what her own views are on feminism. Besides, Miss Winters herself is never seen wearing trousers and does not call herself 'Ms Winters'.

*Kettlewell changes from a good boffin to the villain of the piece and back again, in a most unconvincing way just as Jellicoe can't decide if he's a squeamish villain or a Nazi maniac. 
::Kettlewell's motivations are explained - he is initially pretending to be unaware of ThinkTank's activities so that UNIT will trust him. For all his issues with human society however, Kettlewell isn't willing to see it totally destroyed, hence why he starts helping UNIT again later in the story. Jellicoe seems to be consistent throughout.

*The robot's motives change from scene to scene and show contradictory programming regarding obeying orders and striving for self preservation. 
::That is part of the inner conflict that the story is about.

*The Doctor chops a brick in half, but it's clearly a block of balsa wood. Listen for the noise when it hits the ground. What is a brick doing there in the lab anyway. 
::There are any number of possible reasons why the brick may be there. Since this is the Doctor's lab after all, the substance it is made of could be anything. What sound it should make is indeterminate.

*The height of the robot is inconsistent after it grows to a huge size. 
::An effect of the living metal.

*Why does all the robot's non-metallic circuit components (e.g. plastic wire coatings, transistors, resisters, diodes, eye lenses, flashing bulbs, etc) also grow with the robot when he is hit with the disintergrator gun? 
::It's never indicated what they are made of, but they obviously are somehow connected with the living metal.

*The plot continues to contradict itself when it is revealed that the SRS's plan of using the nuclear codes to blackmail the world can be cancelled with a simple fail-safe.

*The lynchpin of the plot makes no sense whatsoever. In an effort to defuse international tension, the superpowers would allow Britain (which was neutral in the Cold War) to publish the codes that would allow anyone in the world to launch their nuclear missiles?

*The elite UNIT soldiers not only let a slow-moving 3-metre tall silver robot escape from them, at various points during the firefight, they are shooting at each other.

*The note the Doctor leaves on the TARDIS is very short when he posts it but much longer when Sarah reads it.

*It is highly unlikely that the UK would be regarded as a 'neutral' country by Russia or China.
::Most of Russia and China's quarrels are with the United States and in the Whoniverse the UK may have decided to have little to no presence in the Cold War.
