Theory:Doctor Who audio discontinuity and plot holes/Relative Dimensions


 * The Doctor says that he took Leonardo to see the birth of Jesus "in the Year 0". However, there is no 'Year 0'. The Year 1 BC is followed by the Year 1 AD.
 * Maybe he isn't being literal. He might simply be explaining it in the simplest possible terms.
 * But 'the simplest possible terms' would be saying "the Year 1". And when we take into account that this is the Doctor, it just makes it all the more absurd.
 * While it's certainly not the intended situation, "the Year 0" could be a location rather than a date, and Jesus' birth a holographic simulation rather than the genuine article. Alternatively, the Whoniverse dating is somewhat different from our own?


 * When Susan and the others look at the rooms, they are the rooms of Susan Foreman, Ian Chesterton, Barbara Wright, Vicki Pallister, Steven Taylor, Dodo Chaplet, Polly Wright, Ben Jackson, Jamie McCrimmon, Victoria Waterfield, and then they go to the end where Tamsin Drew's room is. This means that these Audios don't recognise John and Gillian. But it also means that they don't recognise Big Finish's own Companion Chronicle series, as there are no rooms for Sara Kingdom or Oliver Harper. And there should probably also be a room for Katarina.
 * Leaving aside the relative brevity of Katarina's stay in the TARDIS, as well as the fact that certain materials can't even agree that John and Gillian existed, it is possible that some of the rooms were simply reused. Additionally, given that rooms have been jettisoned from the TARDIS before, perhaps Oliver and Sara Kingdom's were among the casualties.
