Egentligen han ljög (nu är det något nytt ... men i det ögonblicket bestämde han sig förmodligen att bli Hybrid, se nedan) som transcript av" Hell Bent "visar (betona min):
[Cloisters]
ASHILDR: Sometimes you do. It's always the way with things we'd rather forget. You remember now, though, don't you? Tell me, Doctor, who is the Hybrid? Who threatens all of Time and Space?
DOCTOR: Oh, but that's easy. That's very, very easy. The Hybrid is you.
[Tardis]
ASHILDR [on scanner]: I'm human, with a little bit of Mire inside me. The Hybrid is supposed to be half Time Lord, half Dalek.
DOCTOR [on scanner]: No, it isn't.
[Cloisters]
DOCTOR: The actual prophecy specifies only two warrior races. The Daleks and the Time Lords have made assumptions, of course. And they would. Humans and the Mire, both warrior races. It fits perfectly.
ASHILDR: It's an interesting theory.
DOCTOR: Do you have a better one?
ASHILDR: By your own reasoning, why couldn't the Hybrid be half Time Lord, half human? Tell me, Doctor, I've always wondered. You're a Time Lord, you're a high-born Gallifreyan. Why is it you spend so much time on Earth? (Because in the Movie, the Master worked out that the Doctor's really half-human - on his mother's side.)
DOCTOR: That's your best theory? I'm the Hybrid? I ran away from Gallifrey because I was afraid of myself? That doesn't make any sense.
ASHILDR: It makes perfect sense, and you know it. Am I right? Is it true?
DOCTOR: Does it matter?
ASHILDR: No. Because I have a better theory.
DOCTOR: Really?
ASHILDR: What if the Hybrid wasn't one person, but two?
DOCTOR: Two?
ASHILDR: A dangerous combination of a passionate and powerful Time Lord and a young woman so very similar to him.
[Tardis]
ASHILDR [on scanner]: Companions who are willing to push each other to extremes.
DOCTOR [on scanner]: She's my friend. She's just my friend.
ASHILDR [on scanner]: How did you meet her?
CLARA: Missy!
[Cloisters]
DOCTOR: Missy.
ASHILDR: Missy. The Master. The lover of chaos, who wants you to love it, too. She's quite the matchmaker.
DOCTOR: Clara's my friend.
ASHILDR: I know. And you're willing to risk all of Time and Space because you miss her. One wonders what the pair of you will get up to next.
DOCTOR: Nothing. Nothing at all. I know I went too far. I get it. That's why I'm doing what I'm doing.
ASHILDR: And what would that be?
DOCTOR: I'm taking her back to Earth. Somewhere safe, somewhere out of the way. I'm going to wipe her memory of every last detail of me.
Så kärnan av det är, doktorn visste faktiskt inte förrän Ashildr gnuggade sin näsa i svaret. Och hybriden är inte honom
alone, but him and Clara together.
Hans påstående att vara hybrid är ganska baserat på den profetia han citerar
Efter det som Timelords gjorde till honom, så gjorde han dem (eller åtminstone bekännelsesklockan) vet att han "bara" 1 nu har bestämt sig för att bli Hybrid och tår Gallifrey ner. Självklart, efter att ha haft lite tid att tänka på det, inledde han sig inte bara händelserna av "Hell Bent" som i sin tur gjordeThe Hybrid destined to conquer Gallifrey and stand in its ruins...
threaten all of time and space because the Doctor wanted to save Clara and thus almost fulfilling the prophecy.
