What happens when the Doctor runs out of regenerations?
Audience Member: This question for Mr. Moffat. How are you going to keep doing the regenerations because, the Doctor is only supposed to have 12 and he's used them all up apart from that last one.
Moffat: First of all, he can regenerate 12 times and that would mean there would be 13 Doctors. What we'll do in the event that we reach that point, and we've had 13 Doctors, there's this emergency BBC protocol. We will....make something up.
