So, we have a female Doctor, after months of speculation. Well, we have had a female version of the Master, everyone says, so why not a female Doctor? I think if they had given us a male Doctor after all that, there would have been howls of outrage from the fans. Especially after that scene where the Doctor tells Bill that Timelords don't worry about all that gender stuff. If that wasn't a powerful hint, then we needed a big marching band, preferably all female, to announce it.
Me, I will wait for the stories before judging. All I can say is, if XX or XY Chromosomes don't count among Timelords, then that race is very, very different from ours, and it's a lot more than the two hearts, so it's highly unlikely that the Doctor is half human as suggested in the Paul McGann film. And I say this as a great Spock fan.
Are all Gallifreyans Timelords? Do you get peasant Timelords like the peasant elves we meet in The Hobbit? There must be someone to grow the food and wash the dishes and so on. And as I recall, there was a barn in one episode. The Day Of The Doctor, I think. So yes, there probably are people on Gallifrey who don't go having adventures in time and space or playing politics on the Council of Timelords. Didn't Leela marry one? It's been a long time since I saw that episode, so don't complain if I got it wrong, just inform me.
If there are ordinary people on that planet who don't regenerate, are they more like us, apart from the two hearts? With XX and XY chromosomes that don't allow them to change gender except by medical means? When you think about it, regeneration with the option of a new cycle of twelve for everyone could stuff up inheritance and you'd really have to keep the population down.
Or it might just be those who graduate from the Academy who get that privilege... As I recall, the Master was offered a new round of regenerations in return for helping the Doctor in The Five Doctors, and it has since then been confirmed, so ability to regenerate can't be merely a genetic thing. And if it's not genetic, perhaps they can get around this whole chromosome issue. Problem solved!
Do the Timelords perhaps bring in children who have shown certain abilities for training and give them the ability as part of the deal?
Certainly, the Master has some amazing abilities. Think of the number of times he has come back from the dead, even in the Paul McGann movie, when the previous Doctor was bringing back his ashes, for heaven's sake! Maybe he/she will come back yet. In fact, I predict they will. Let's face it, we saw the last Dalek in New Who series 1 and we STILL have them!
We know that there are children on Gallifrey - remember that episode where the Doctor is talking about how they are taken to stare into this abyss(he sensibly ran away)and we see a flashback in which a young boy who will become the Master is taken there and, it's implied, goes crazy as a result? (Talk about child abuse!) And yet, the first Doctor we saw was an old man with a granddaughter - seeing he was the first incarnation, not the first regeneration, surely he grew up and aged this first time. Hell, he must have been a child at some stage!
There was an article in a fanzine I read years ago, speculating on what a Timelord family picnic might look like - the elderly man might be the youngest family member while the young girl is an aged Timelord on her final regeneration...that would be bizarre!
One thing that I have always found mildly amusing is the matter of Susan. As far as we know, she is his granddaughter. That implies some sort of family life, or maybe a companion who managed to get into his pants. But as I recall, there was an early novel which told us that Susan was not actually related, she just called him "grandfather". See, someone worked out that having a granddaughter implied that at least once the Doctor must have fooled around - can't have that on a children's show!
And with that particular silliness I will leave you. Feel free to comment, although if you have seen every last episode and remember the lot, I should explain that this is not the case with me and I would appreciate not being abused for having forgotten something. Let's keep this fun!
