Re: Renumber The Doctors?
While Capaldi might be the 13th, it really doesn't make much sense to adjust the last 3 retroactively. If Voyager introduced a secret Enterprise between B and C we wouldn't suddenly start calling the D the E and the E the F, etc. As far as 8, 9 and 10 are concerned he is an aberration that doesn't deserve the name, and 11 only knows the truth after the events of The Day of the Doctor, so just let him be The War Doctor and there simply won't be a 12th Doctor.
That's hardly comparative because each of the Enterprises are different ships while The Doctor is the same physical person with different faces and personalities.
