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


 * When the Doctor disables the Emotional Inhibitor, why does this not affect the newly-converted John Lumic?
 * It does. He pursues the Doctor and his companions with rage and frustration. He might very well have seen himself as he had become. Yet due to the power of his mind (he was a genius) he might have been able to overcome his pain in order to vent his revenge on the Doctor.


 * If only the Brain is needed in a Cybersuit, why do the Cyber-Converters appear to chop up body parts?
 * Easier disposal? Keeping part of the nervous system alive by cutting around it so they don't need to grow as much?


 * When Rose and Pete are putting on the fake earpods her hair is tucked behind her ears however when she stands up it is not.
 * Long hair can be untucked if she does stand up. Anyone's hair that is long can move if they stand up. It's not like all of her hair is super glued to her head


 * If Lumic's so keen on the glory that is Cyberness, why is he so reluctant to be Cyberfied himself? Also, why does he need a tube-ridden chair and dry ice afterwards?
 * Possibly because he knew the pain and horror or being upgraded, plus the tube-chair might have been him wired into the cyber-network to give him greater control of the Cybermen, it might even simply be a throne, which would explain the dry ice, either that or it's just for effect.


 * There is one scene in the rain where Cybermen cry out in pain. This is the only scene where rain is seen. Also, when Rose, Pete and the Doctor are saved by Mickey and Jake, no clouds are seen.

after this episode, Rose has a different phone I'm sure. Maybe a production error, or maybe it happened off screen.
 * 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.
