QUELL: So, what are you a doctor of?

DOCTOR: Now, there's a question that's never asked often enough. Let's say intestinal parasites.

PERKINS: You know, Doctor, I can't tell if you're a genius or just incredibly arrogant.

DOCTOR: Well, ah, on a good day, I'm both.

DOCTOR: I'm so pleased to finally see you. I'm the Doctor and I will be your victim this evening. Are you my mummy?

DOCTOR: Sometimes the only choices you have are bad ones. But you still have to choose.

PERKINS: Perkins. Chief Engineer.

DOCTOR: The Doctor. Nosey Parker.

DOCTOR: Let me tell you about scared. Your heart is beating so hard, I can feel it through your hands. There's so much blood and oxygen pumping through your brain, it's like rocket fuel. Right now, you could run faster and you could fight harder, you could jump higher than ever in your life. And you are so alert, it's like you can slow down time. What's wrong with scared? Scared is a superpower. It's your superpower. There is danger in this room and guess what? It's you.

DOCTOR: This is Clara, not my assistant. She's, er, some other word.

CLARA: I'm his carer.

DOCTOR: Yeah, my carer. She cares so I don't have to.
