Re: A thought on regenerations (spoilers for "Night/Day of the Doctor"
Actually, I think the Meta Crisis Doctor looks more like a spin-off from the Doctor, thus for the Eleventh Doctor really being actually the Twelfth incarnation of the Doctor.
I don't see how that follows. My understanding of the Season 6B theory is that yes, they did regenerate Troughton into Pertwee, but only after sending him on missions including "The Two Doctors."
I've always wondered why it was just the Doctor and Jamie in that story. Since no female companion was mentioned, there had to have been a time between Victoria and Zoe when it was just the Doctor and Jamie...
Actually, Victoria is mentioned briefly in The Two Doctors
, as follows:
: We don't usually get to where you say we're going.
The Second Doctor
: I got Victoria to where she wanted to go. Why she wants to learn graphology, I have no idea!"
Basically, the Doctor asked to have Jamie accompany him for his missions, and off they went for The Two Doctors
"Spock...?" Kirk said, whispering.
"I am... most pleased to see again, Captain" Spock formally replied.
McCoy shook his head in disgust. "Oh, for crying out loud, Spock. Its been eighty years!"
"Seventy eight point four years, Doctor."
