"Oh. You like a cliffhanger, don’t you?" Clara Oswald, Doctor Who - S09E12

Stories are where memories go when they’re forgotten.

Clara: Tell me what they did to you. Tell me what happened to the Doctor.

Clara: The Hybrid. What is it? What’s so important you would fight so long? The 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 and I’d have nothing left to bargain with. Clara: What were you bargaining for? The Doctor: What do you think? You. I have to find a way to save you. I knew it had to be the Time Lords. They cost you your life on Trap Street, Clara. And I was going to make them bring you back. I just had to hang on in there for a bit. Clara: How long? The Doctor: It was fine.

Clara: One question. And you will answer. How long was the Doctor trapped inside the Confession Dial? Ohila: We think… four-and-a-half billion years. The General: He could have left anytime he wanted. He just had to say what he knew. The Dial would have released him.

Clara: Four-and-a-half billion years? The Doctor: If she says so. 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? The Doctor: I had a duty of care.

Clara: Okay, listen. I have something I need to say. The Doctor: We do not have time! Clara: No, my time— my time is up, Doctor. Between one heartbeat and the last is all the time I have. People like me and you, we should say things to one another. And I’m going to say them now.
