Will David Tenant come back as Doctor Who as doctor 12?

Answer 1

Regular viewers of the show will have picked up on the ‘Cracks in the universe‘ to which many fans believe that later in the series,Billie Piper and Tennant will reprise their roles as ‘Rose Tyler‘ and ‘Meta-Crisis Tenth Doctor‘ who was last seen in the episode ‘Journey’s End.’ It’s theorized that the cracks in the universe will allow a cross over between realities.

Also of interest is the concept of ‘TARDIS Coral‘ the substance which TARDIS‘ are in fact grown from (grown, not built.) In the DVD Box set, there was a scene at ‘Bad Wolf Bay‘ where The Doctor gives ‘Meta-Crisis Doctor’ a piece of TARDIS coral which would take thousands of years to grow into a fully fledged working TARDIS. However, Donna, still influenced by the Meta-Crisis previously mentioned in the episode tells the ‘Meta-Crisis Doctor’ and Rose that the growth of the TARDIS coral can be accelerated by suggesting “…if you shatterfry the plasmic shell and modify the dimensional stabiliser to a foldback harmonic of 36.3, you accelerate growth by the power of 59!” Whilst the scene was not aired as it would add complications to Rose’s departure, it’s very well in the realm of probability that the TARDIS coral could be written in to a future script.

One last possibility is that 2013 may hold a return of Tennant as the show celebrates its 50th Anniversary, making room for the possibility of a Doctor Who special.
