DOCTOR: Nothing’s sad until it’s over, and then everything is.

CLARA: No. Why would you even do that? I was dead! I was dead and gone. Why? Why would you even do that to yourself?

DOCTOR: I had a duty of care.

DOCTOR: It doesn't matter what the Hybrid is. It only matters that I convinced them that I knew. Otherwise they'd have kicked me out, I'd have had nothing left to bargain with.

CLARA: What were you bargaining for?

DOCTOR: What do you think? You. I had to find a way to save you.

DOCTOR: Never eat pears. They're too squishy and they always make your chin wet. That one's quite important. Write it down.

CLARA: I don't think I could ever forget you.

DOCTOR: Clara, I don't think you're ever going to have to.

CLARA: There has to be something I can do.

DOCTOR: Smile for me. Go on, Clara Oswald, one last time.

CLARA: How could I smile?

DOCTOR: It's okay. Don't you worry. I'll remember it.

DOCTOR: Run like hell.

CLARA: What?

DOCTOR: Run like hell because you always need to. Laugh at everything because it's always funny.

CLARA: No, stop it. You're saying goodbye. Don't say goodbye.

DOCTOR: Never be cruel, never be cowardly, and if you ever are, always make amends.

DOCTOR: When something goes missing, you can always recreate it by the hole it left. I know that there was an ice warrior on the submarine and a mummy on the Orient Express. I know we sat together in the cloisters and she told me something very important, but I have no idea what she said... Or what she looked like... Or how she talked... Or laughed.

CLARA: You don't know who you're looking for, I mean... She could be me, for all you know.

DOCTOR: There's one thing I know about her. Just one thing. If I met her again, I would absolutely know.

CLARA: You said memories become stories when we forget them. Maybe some of them become songs.

DOCTOR: A long time ago, there was a student at the Academy. He got in here, disappeared for four days. Showed up in a completely different part of the city. Said the Sliders talked to him, they showed him the secret passage out. And we just need the code.

CLARA: What, and the kid told you the secret?

DOCTOR: Ah, no, he didn't tell anyone anything. He went completely mad, never right in the head again. So they say. Last I heard, he stole the moon and the President's wife.

CLARA: Was she... Was she nice, the President's wife?

DOCTOR: Ah well, the was a lie put about by the Shabogans. It was the President's daughter. I didn't steal the moon, I lost it...

CLARA: I'd know you anywhere.

RASSILON: You missed. All of you. Every single one of you! How is that possible? What is it? Is the firing squad afraid of the unarmed man?

(Rassilon grabs Gastron by the scuff of the neck.)

RASSILON: You, explain.

GASTRON: There was a saying, sir, in the Time War.

RASSILON: A saying?

GASTRON: The first thing you will notice about the Doctor of War is he’s unarmed. For many, it’s also the last.
