Post by The DoctorRiver Song's ability to regenerate is due to her being exposed
to the time atoms of the TARDIS.
Not proven.
The only evidence supporting this theory is a few moments of pure
speculation between Vastra, Dorium Maldovar and the Doctor in “A Good Man
Goes to War”. And it’s not even the Doctor’s speculation.
DOCTOR: You've hacked into their software, then?
DORIUM: I believe I sold it to them.
DOCTOR: Ooo. So what have we learned?
[..]
VASTRA: Now, I have a question. A simple one. Is Melody human?
DOCTOR: Sorry, what? Of course she is. Completely human. What are you
talking about?
DORIUM: They've been scanning her since she was born, and I think they
found what they were looking for.
DOCTOR: Human DNA.
VASTRA: Look closer. Human plus. Specifically, human plus Time Lord.
[…]
DOCTOR: But she's human. She's Amy and Rory's daughter.
VASTRA: You've told me about your people. They became what they did through
prolonged exposure to the time vortex. The Untempered Schism.
DOCTOR: Over billions of years. It didn't just happen.
VASTRA: So how close is she? Could she even regenerate?
DOCTOR: No, no. I don't think so.
VASTRA: You don't sound so sure.
DOCTOR: Because I don't understand how this happened.
VASTRA: Which leads me to ask when did it happen?
DOCTOR: When?
VASTRA: I am trying to be delicate. I know how you can blush. When did this
baby begin?
DOCTOR: Oh, you mean
VASTRA: Quite.
DOCTOR: Well, how would I know? That's all human-y, private stuff. It just
sort of goes on. They don't put up a balloon, or anything.
VASTRA: But could the child have begun on the Tardis in flight, in the
vortex.
DOCTOR: No! No! Impossible! It's all running about, sexy fish vampires and
blowing up stuff. And Rory wasn't even there at the beginning. Then he was
dead, then he didn't exist, then he was plastic. Then I had to reboot the
whole universe. Long story. So, technically the first time they were on the
Tardis together in this version of reality, was on their w
VASTRA: On their what?
DOCTOR: On their wedding night.
[…]
DOCTOR: It doesn't make sense. You can't just cook yourself a Time Lord.
VASTRA: Of course not. But you gave them one hell of a start, and they've
been working very hard ever since.
DORIUM: And yet they gave in so easily. Does this not that bother anyone
else?
DOCTOR: Amy. She worried the baby would have a time head. She said that
VASTRA: Only you would ignore the instincts of a mother.
DORIUM: Or the instincts of a coward. This is too easy. There's something
wrong.
DOCTOR: Why even do it? Even if you could get your hands on a brand new
Time Lord, what for?
It’s equally possible that Madam Kovarian obtained Time Lord DNA from
elsewhere and manipulated Melody Pond in infancy, for example.
Post by The DoctorThe Timeless Child is contradicted!
No, if what is said in AGMGTW is correct, River Song contradicts the
previous canon. Cartmel master plan aside (not canon!) all Time Lords are
Gallifreyan. And “They became what they did through prolonged exposure to
the time vortex. The Untempered Schism.” is actually - a bit vague. It’s
hearsay evidence from someone who is notoriously an unreliable narrator and
was a poor student, and it doesn’t even specify “what” they became. It
could just refer to their arrogance and ability to detect changes in the
time stream, to recognise fixed points in time and affect the course of
reality.
It doesn’t alter the bloody stupid Timeless Child legend at all, doesn’t
contradict it, and the Timeless Child doesn’t contradict this story. This
story may not even be TRUE.
