Theory:Doctor Who television discontinuity and plot holes/Rise of the Cybermen


 * Rose informs the Doctor that Mickey's parents are gone and that his grandmother raised him, but had stated earlier in Rose that she would have to tell his mother about his death.
 * She said his mother could not cope and left. She never said whether Mickey was in contact with her or not, so she may have meant she might have to visit Mickey's mother to tell her.
 * Rose was gone a whole year with the Doctor. His mother could have died in that time.
 * Mickey may have been in contact as an adult since his grandmother's death.


 * When Rose decides to go look for her father, she defends by saying "You said 24 hours!" The Doctor hadn't told that to her as he and Mickey had just seen her.
 * The Doctor had told her. When he and Mickey find her, the Doctor says "24 hours".


 * The Doctor and Rose don't have earpods when they are posing as the catering staff, wouldn't they get noticed?
 * It might be expected that servants wouldn't wear them at work. Much like blue-tooth devices it would be considered rude. I disagree with you there because Lucy - the other servant was waearing ear pods
 * Similar to how people from the past do not comment on their attire, people from the present may not.
 * Since they are servants, they may not be thought to be rich enough so no-one would say anything.
 * They are servants, so no-one would take notice of them.


 * The Doctor says in Inferno that taking the alternate Brigadier, Liz Shaw, Dr. Williams, Mr. Sutton, etc. to his universe would cause a cosmic catastrophe, yet Mickey and Ricky are able to coexist without incident.
 * We do not know if the Inferno universe and the Pete's World universe work to the same rules. Also, the Doctor could have been mistaken as he was much younger then.
 * The presence of the TARDIS on Pete's World or the lack of the Time Lords might have also influenced things.


 * After the Cybermen delete the president, why do they start deleting everyone else, even though they don't know if the people they are deleting want a 'free' upgrade?
 * Everybody started running, so the Cybermen assumed they were refusing.
