Steven Moffat has revealed that, as many
have speculated, Matt Smith is the last life of the Doctor. To give context, a
Time Lord has thirteen lives, facilitated by 12 regeneration cycles. The War
Doctor took up one of those cycles and the Tenth Doctor wasted one in order to
heal himself in “Journey’s End”. This means that when Ten regenerated into
Eleven he used his last regeneration cycle and is no longer capable of brining
himself back to life in a different body.
So how’s he gonna do it?
Peter Capaldi has the role; he even
appeared as the Twelfth Doctor in “The Day of The Doctor”so how will he
survive.
Theories:
The limit is artificial:
It could be that the higher ups in Time
Lord society, such a Rassilon and other members of the council could regenerate
as many times as they wanted and that lowers such as the Doctor and the Master
were limited as a means of ultimate control over them. Part of the Second Doctor’s
punishment at the conclusion of his trial was to be forced to regenerate,
effectively bringing him one cycle closer to the limit; a warning shot if you
like, to tell him to stop breaking the rules or they’d burn out all his lives.
This also showed that the Time Lords could control aspects of the Doctor’s
regeneration such as his appearance; meaning that they could feasibly have the
power to control how many times one could regenerate.
Of course this theory doesn’t really
stand up as if they artificially controlled the regeneration cycles, there’s no
reason that they wouldn’t have just stripped him of his ability to regenerate
at all and told him he was welcome to break the rules, in the knowledge that
when one his adventures inevitably got him killed he’d be dead for good. The
revived series has also demonstrated that the process is born out of
regenerative energy, which would suggest that the limit is caused by this
energy being too depleted to bring a Time Lord back to life properly. In fact
the Master attempted to regenerate after exhausting his cycles and turned into
a disgusting hooded creature, presumably a half regenerated body.
The Doctor Will be Resurrected
So Gallifrey is still out there somewhere
and the Doctor is tasked with finding it. Add to that that Capaldi’s Doctor
didn’t seem to be present on Trenzalore (at the Doctor’s grave) and all
indications are that Matt Smith’s Doctor will die and be buried at Trenzalore
and then the new Doctor will be the product of a Time Lord resurrection,
something the Time Lords reserve only when absolutely necessary; like bringing
the long dead Master back for the Time War. If the Doctor were to be
responsible for bringing the whole of Gallifrey back from the Pocket Universe,
he may be rewarded by another life cycle. He would still be dead and buried at
Trensalore, but the Twelf Doctor would effectively be a new First Doctor, with
a full set of new regeneration cycles, like the new Master. This is the most
likely way around the limit and does fit with the established grave of the
Doctor.
But who truly knows? Steven Moffat could
simply be lying about not being able to break the rules as he frequently has in
the past. But after what I consider a very successful 50th anniversary,
I am confident that whatever he comes up with will be clever and entertaining.
