Theory:Doctor Who television discontinuity and plot holes/The Age of Steel


 * When the Doctor disabled the Emotional Inhibitor, why did this not affect the newly-converted John Lumic?
 * It did. He pursued the Doctor and his companions with rage and frustration. He might very well have seen himself as he had become, but due to the power of his mind, as he was a genius, he might have been able to overcome his pain in order to vent his revenge on the Doctor.
 * Lumic planned to be converted eventually. He wished to become like that.


 * If only the brain is needed in a Cybersuit, why do the Cyber-Converters appear to chop up body parts?
 * It is not known what it chops up. It could easily just be cutting the brain out and creating places for it to be linked up.
 * The machines also need to remove nervous systems, so likely had to remove other body parts to access it.


 * If Lumic was so keen on everyone becoming Cybermen, why is he so reluctant to be converted himself?
 * He may have wanted to live as long as possible in his Human body so that if any problems arrived he could fix them easier.


 * Why does Lumic need a tube-ridden chair and dry ice afterwards?
 * It is shown that he did not need it since he chases the Doctor, Rose and Pete.
 * It may help him control the Cybermen and/or electronics.
 * The chair may simply be a throne for effect.


 * The Doctor told Mickey to take Rose's phone as it stored the code to break the emotional inhibitor, yet when they say goodbye for what they think is the last time, Mickey doesn't receive Rose's phone.
 * It could have been given to him off screen.


 * After this episode, Rose has a different phone.
 * When the factory is exploding, they just re use explosion footage from Rose.
 * Given that Mickey had taken the phone, believed to be off-screen, it is understandable that she would purchase or obtain another one.
