It’s a question as old as time – just how many times can the Doctor regenerate? We know the canonical answer – 12 – which dictates that there can only be 13 Doctors, and then he’s dead. But we also know that there are ways around it (the Time Lords offered the Master another regeneration, and he’s cheated it several times already). And, of course, it’s science fiction – they can just come up with something new. But it sounds like we will get a definitive answer – at least for the Doctor – in an upcoming episode of The Sarah Jane Adventures.
The two-part episode “Death of the Doctor” (to air as episodes 5 and 6), airing towards the end of this month in the U.K. (no U.S. airings are scheduled yet), is being written by Russell T. Davies and will feature Matt Smith as the 11th Doctor, and the return of Jo Grant (Katy Manning), one of the Third Doctor’s companions. And among some teaser lines provided by Digital Spy (who saw a sneak peak), “The Doctor doesn’t have to be white. And he can regenerate more than 12 times – a lot more!”
