What about the year that never was? The people in the close vicinity remembered the year so obviously their pasts did not get erased, just everyone elses. That would add another year to the 10th doctors age.
In regards to the 900 controversy, in Aliens of London, the Doctor states that 900 years is the amount of time he's been travelling for, not how old he is. Perhaps after this, he just used 900 years in reference to his life after leaving Gallifrey.
- I Always assumed that it was just him (and the writer's) excuse to make up some age when in reality after the Time War and other things he had totally lost track. After all, he may think he has spent roughly 100 years in each incarnation (it could be much longer but memory does tend to blur if you don't recall it for a while), so after nine incarnations he decided that 900 a good number "for show" in a way. After that, in the time when Voyage of the Dead occurred, it was three yr=ars after the point in time where he said 900, so he thought it would make sense to take those into account. Anyways its just a theory--99.135.150.62 02:01, May 17, 2010 (UTC)
this article claims that the figure in the astronought suit who kills the doctor in the impossible astronought is a silence, but no other article or source suggests this. unless there is a source for this, it should be removed. if there is, it should be mentioned on the page for the eleventh doctor, and the silence, at the very least.
