The Doctor and Rupert in “Listen”

[to Rupert] Are you scared? The thing on the bed, whatever it is… Look at it, does it scare you?

Yes.

Well, that's good. Want to know why that's good?

Why?

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 can 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 super power! It's your super power! There is danger in this room, and guess what? It's you. Do you feel it? [Rupert nods. The Doctor nods at the creature on the bed] Think he feels it? Do you think he's scared? [Rupert shakes his head] [mockingly] Nah. Loser.
