Article is pretty messed up. Claims it's the real Doctor. Ok, but then says maybe between the 2nd and 3rd because Ruth didn't recognize the sonic screwdriver. Um. Troughton was the first with the sonic! At least they got the thing about Hartnell being the first with the Police Box shape. And, Jack not showing up again this year? Sounds like the director of the finale shot his scenes . . . um. Oops. And, even if it were true, how stupid to not have Jack meet the Doctor. I can't believe they'd pass that up.
Stuff isn't adding up. Not sure what the truth is, but it's not all the straight scoop.
I would also say that a Doctor from an alternate universe is a real Doctor . . . from that universe. Just like Pete was the real Pete from his universe.
