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


 * The film crew is reflected in Mickey's grandmother's glasses.


 * Rose informs the Doctor that Mickey's parents are gone and that his grandmother raised him, but had stated earlier in DW: Rose that she would have to tell his mother about his death.
 * Foster mother? ''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, also remember, Rose was gone a whole year with the Doctor, his mother could have died. 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!", while the Doctor hadn't had told that to her as he and Mickey had just seen her.


 * The Doctor and Rose don't have earpods when they are posing as the catering staff, wouldn't they get noticed?
 * It is implied at the start that Jackie has only just got her earpods maybe not everyone has them. It might be expected that servants wouldn't wear them at work, much like bluetooth devices it's considered rude. People might just not say anything, its a bit like when they turn up in the past you would think someone would make comment on their attire.


 * 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 (he was much younger then). The presence of the TARDIS on Pete's World might have also influenced things. The Doctor also repeatedly warns users of the Dimension Hopping Disks in Doomsday and The Stolen Earth that they are damaging the fabric of Space Time by using the devices.


 * 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?
 * Everbody started running so the Cybermen assumed they were refusing.
