“One day, I shall come back — yes, I shall come back. Until then, there must be no regrets, no tears, no anxieties. Just go forward in all your beliefs, and prove to me that I am not mistaken in mine. Goodbye, Susan, goodbye, my dear.”

“I love humans. Always seeing patterns in things that aren’t there.”

“As we learn about each other, so we learn about ourselves.”

SETH: If we don't pay tribute, the Nimon will destroy us.

ROMANA: Sounds like an insecure personality to me.

SETH: He lives in the power complex.

ROMANA: That fits.

ROMANA: Oh, I do love the spring. All the leaves, the colours.

DOCTOR: It's October.

ROMANA: I thought that you said we were coming here for May week.

DOCTOR: I did. May week's in June.

ROMANA: I'm confused.

DOCTOR: So was the TARDIS.

ROMANA: Oh, I do love the autumn. All the leaves, the colours.

DOCTOR: The Earth isn't my home, Sarah. I'm a Time Lord.

SARAH JANE: I know you're a Time Lord.

DOCTOR: You don't understand the implications. I'm not a human being. I walk in eternity.

SARAH JANE: What's that supposed to mean?

DOCTOR: It means I've lived for something like seven hundred and fifty years.

SARAH JANE: Oh, you'll soon be middle aged.

“Fear makes companions of all of us.”

“It's still a police box. Why hasn't it changed? Dear, dear, how very disturbing.”

DOCTOR: Grace, let me in. We can sit down, we can have a cup of tea, we can talk about this reasonably.

GRACE: Sure, Time lord to Earthling.

DOCTOR: Yes, that's right. I am a Time Lord.

GRACE: I thought you were a doctor.

DOCTOR: I thought you were a doctor!

GRACE: I am calling an ambulance to take you back to Psychiatric from which you have obviously escaped!

(The Doctor gives Jo the Metabelis crystal.)

JO: It's beautiful. Thank you, Doctor.

JONES: Hey, Jo, come and drink a toast to the happy couple.

JO: But that's us.

JONES: Aye, so it is. Don't worry, Doctor. I'll look after her.

POLICEMAN: Sir, ma'am, go back to your vehicle.

GRACE: What? Stop! He's er, he's British.

DOCTOR: Yes, I suppose I am. Jelly baby, officer?

POLICEMAN: Jelly baby?

GRACE: Just take it.

(The policeman takes a sweet and sniffs it while the Doctor makes lip-smacking noises. When he bites into it, the Doctor takes his gun and points it at his own chest.)

DOCTOR: Now, would you stand aside before I shoot myself.

JO: We’re still on Earth, aren’t we?

DOCTOR: No, that’s impossible.

JO: Don’t you ever admit that you’re wrong?

DOCTOR: No, that’s impossible too.

JO: I only left you because I got married. Did you think I was stupid?

DOCTOR: Why do you say that?

JO: I was a bit dumb. Still am, I suppose.

DOCTOR: Now what in the world would make you think that, ever, ever, ever?

JO: We'd been travelling down the Amazon for months, and we reached a village in Cristalino, and it was the only place in thousands of miles that had a telephone, so I called you. I just wanted to say hello. And they told me that you'd left, left UNIT, never came back. So I waited and waited, because you said you'd see me again. You did, I asked you and you said yes. You promised. So I thought, one day, I'd hear that sound, Deep in the jungle, I'd hear that funny wheezing noise, and a big blue box right in the middle of the rainforest. You see, he wouldn't just leave. Not forever. Not me. I've waited my whole silly life.

DOCTOR: But you're an idiot.

JO: Well, there we have it.

DOCTOR: No, but don't you see? How could I ever find you? You've spent the past forty years living in huts, climbing up trees, tearing down barricades. You've done everything from flying kites on Kilimanjaro to sailing down the Yangtze in a tea chest. Not even the TARDIS could pin you down.

JO: Hold on. I did sail down the Yangtze in a tea chest. How did you know?

DOCTOR: And that family. All seven kids, twelve grandchildren, thirteenth on his way. He's dyslexic but that'll be fine. Great swimmer.

JO: So you've been watching me all this time?

DOCTOR: No. Because you're right, I don't look back. I can't. But the last time I was dying, I looked back on all of you. Every single one. And I was so proud.

JO: It really is you, isn't it?

DOCTOR: Hello.
