The question of precisely how many lives DOCTOR WHO’s title character will live just refuses die; and lately it’s been regenerating with increasing frequency, thanks to the impending arrival of the Doctor’s 12th incarnation, as well as the suggestion that another Doctor is going to be retroactively inserted into the established order, bumping the Doctors ahead one incarnation.
No matter which number Peter Capaldi will bear when he takes over as the Doctor after this year’s Christmas Special, I believe there must be a way for the last of the Time Lords to persevere — even if Hurt is inserted into the timeline, and Capaldi become the 13th and (apparently) final Doctor.
BTW, what does it say about DW fandom that so many people are already preoccupied with the question of how long Capaldi is staying with the role? The man hadn’t officially been the Doctor for 10 minutes before people started wondering when he will quit. The near-instantaneous speculations on the 13th Doctor struck me as insulting to the incumbent as well as the show. It appears that Capaldi’s professional stature is working against him; folks cannot imagine that the respected actor will stick with the role for very long.
