Re: The Curator.... Who is he? (SPOILERS for "The Day of the Doctor")
Essentially, he's Moffat's version of the Woman in White from The End of Time. The Woman, of course was intended by RTD to be the Doctor's mother but her identity wasn't stated on screen so that she could be whoever the fans wanted her to be.
I thought she was Susan. Put photos of them side by side, you'll see why.
You know, I DO think so too. Which would be great - it means that, if the Doctor ever finds Gallifrey again, he can find his own granddaughter again.
"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."
