Clara: I never saw that one. I saw all of you. Eleven faces, all of them you. You're the Eleventh Doctor.
The Doctor: I said he was me. I never said he was the Doctor.
Clara: I don't understand.
The Doctor: My name, my real name. That is not the point. The name I chose is "the Doctor." The name you choose, it's like... like a promise you make. He's the one who broke the promise. Clara! He is my secret.
The Other Doctor: What I did, I did without choice.
The Doctor: I know.
The Other Doctor: In the name of peace and sanity.
The Doctor: But not in the name of the Doctor.
