Theory:Doctor Who television discontinuity and plot holes/Human Nature


 * Didn't the Seventh Doctor have a remarkably similar adventure in the book, "Human Nature"? Bit unlikely that it would happen again so similarly.
 * The comics are often times not canon to the show. The comic actually inspired the TV episode, which is why it has many things in common.


 * John Smith's statement that his adventures with Martha take place in 2007 contradict the timeline.
 * Incorrect, they are time travellers. They were in 2007, a year in Martha's relative past, when the Family caught up to them. Martha's myspace blog states that they were attending the Eurovision concert of that year.
 * A related point is that is that it is "John Smith" and not the Doctor who is talking, and that he is relating a dream of his, not necessarily the literal truth experienced by the Doctor.


 * Since the Family would have died out pretty soon, why didn't the Doctor and Martha hide out in the TARDIS, in the Time Vortex, both of which would be practically impenetrable, even for the Family, until it was over?
 * It is mentioned during John Smith's dream that the Family had stolen Time Agent technology, specifically, a Vortex Manipulator. Obviously they'd be able to follow them wherever they went and presumably infiltrate the TARDIS.


 * John Smith said that he learned how to draw on Gallifrey. The Doctor's conversation with Romana II in City of Death suggests that all drawings on Gallifrey are done by computers.
 * Actually it's said that painting is done on computer not all drawings.
 * Also, John Smith is just guessing he learnt to draw there, as it is the place he grew up.


 * How did Martha get John Smith out of the TARDIS without him noticing where he was?
 * A shock most likely occured when the Doctor made himself Human thus causing him to faint and giving Martha the time to get him out of the TARDIS.

That's a production error, not a plot discontinuity.
 * When Martha enters the TARDIS. In the long shot you can see inside the TARDIS, the room inside is lit up but when Marth is inside the walls are dark.
