So now that we know that the Doctor will die at age 1103, still in his Eleventh incarnation, does that mean that Matt Smith will be the last actor to play the Doctor? Obviously, time can be rewritten, but River claims that this will cause a paradox.Icecreamdif 17:22, April 24, 2011 (UTC)
Being logical about the series, I think it's safe to say that the Doctor's death must be undone. The producers of the show simply cannot limit themselves into not letting the Doctor regenerate again. Saying that the Doctor will not regenerate after Matt Smith would not work for them. So the only satisfactory resolution of the story arc is to undo his death. Meanwhile, we know that they cannot allow Song, Amy & Rory to use their knowledge of his death to change its outcome. This would create a Paradox. Now, we know that James Corden is back this series. Remember in The Lodger, there was an unexplained Tardis-looking room? Remember how in the Impossible Astronaut, there was a similar looking unexplained Tardis-looking room. I believe these are related. We have an unexplained room that looks like a TARDIS appearing twice, including in an episode which needs a paradox to be resolved. I think that this is to become a Paradox Machine, like the Master created from the Doctor's TARDIS. The explanation of the room must come from something in the long period in which the Doctor has aged. MichaelBlackburn 17:58, April 24, 2011 (UTC)
They probably will find someway to rewrite time without creating a paradox. Whether or not they use the lodger TARDIS to create a paradox machine, the bigger question is where does it come from. It seems weird that whenever they see a character alive in the future, the Doctor believes that it is still possible for them to die, since time can be rewritten, but when the Doctor of the future dies, they can't change anything because it would create a paradox.Icecreamdif 19:06, April 24, 2011 (UTC)
The explanation for that is the usual: the Doctor inately knows what of time can be rewritten and what of time can't; the rest of them don't. What I don't get is why they can't tell the Doctor what's happened and ask him if his death is set in stone. Kayjeth April 25, 2011
