DAN LEWIS: I've only been back a month, and I've got to say, I'm glad I'm not on the verge of being exterminated any more. But I do miss her.

IAN CHESTERTON: Sorry. Did you say her?

DAVROS: Impossible. That face. After all these years.

SARAH: Davros. It's been quite a while. Sarah Jane Smith. Remember?

DAVROS: Oh, this is meant to be. The circle of time is closing. You were there on Skaro at the very beginning of my creation.

SARAH: And I've learnt how to fight since then.

SARAH: (To the Doctor) You know, you act like such a lonely man. But look at you. You've got the biggest family on Earth.

DOCTOR: Hello, Sarah Jane.

SARAH JANE: [softly] It's you. Doctor. Oh, my God, it's you, isn't it? [realizing] You've regenerated.

DOCTOR: Oh. Half a dozen times since we last met.

SARAH JANE: You look.... incredible.

DOCTOR: So do you.

SARAH JANE: Hm. I got old. What are you doing here?

DOCTOR: Well. UFO sighting. School gets record results. I couldn't resist. What about you?

SARAH JANE: Same.

JACKIE: Well, I reckon you're mad, the pair of you. It's like you go looking for trouble.

DOCTOR: Trouble's just the bits-in-between! It's all waiting out there, Jackie. And it's brand new to me-- all those planets and creatures and horizons! I haven't seen them yet, not with these eyes. And it is gonna be... fantastic!

DOCTOR: You know, I am so constantly outwitting the opposition, I tend to forget the delights and satisfaction of the arts, the gentle art of fisticuffs.

DOCTOR: As we learn about each other, so we learn about ourselves.

DOCTOR: You wanted advice you said. I never give it, never. But I might just say this to you. Always search for truth. My truth is in the stars and yours is here.

DOCTOR: If you could touch the alien sand and hear the cries of strange birds and watch them wheel in another sky, would that satisfy you?
