RYAN: That bit you said earlier, about choosing friends over fear. Is that why you brought us along with you?

DOCTOR: That’s part of it. But not all. You know when you’ve seen your favourite film dozens of times? What’s the one thing you can do to make it feel brand new again?

RYAN: Uh… show it to someone who hasn’t seen it before?

DOCTOR: Exactly! New eyes… they can make even the universe itself feel new too.
