Theory:Doctor Who video game discontinuity and plot holes/TARDIS


 * The Doctor asks Amy a number of questions she would not have known.
 * He's not really asking, more trying to sort out his thoughts. The questions are more for himself than Amy.


 * The Fourth Doctor's scarf is hanging up in the drawing room, but the fifth Doctor unraveled it in Castrovolva.
 * The fourth Doctor had more than one scarf. It was shown to be in the TARDIS wardrobe before. (TV: The Christmas Invasion)


 * The Doctor's fob watch is in the drawing room, and he later uses it, but he gave it to Tommy, in The Family of Blood.
 * There is no reason that he could not have retrieved it after Tommy's death.
 * He also could have had another fob watch.


 * Amy has to rig up a tractor beam to save the Doctor, but in several other stories the TARDIS already has one, activated by the control panel.
 * They were different versions of the TARDIS console. This one may not have one built in.


 * The Doctor can't breath in the time-space vortex here, but in The Time Monster and Shada he seems fine in there, he also mentions in The Enemy of the World, that being thrown out into the vortex wouldn't kill Salamander.
 * It was not the time vortex, it was a rift.


 * There is a scycorax staff in the drawing room, but the Doctor never took one in The Christmas Invasion.
 * He had prior meetings with the Sycorax and could have had more after. It is easily possible that he could have obtained one in many of the gaps in his history.


 * Same goes for Liz ten's mask.
 * The Doctor was specifically given Liz' mask, on screen.
