- The Doctor: I'm a Time Lord.
- Sarah Jane Smith: Whoa, I KNOW you're a Time Lord.
- The Doctor: You don't understand the implications. I'm not a hunan being. I walk in Eternity.
- The Doctor: Of course, it would make an ideal headquarters for some paramilitary organisation. This room could easily be turned into a laboratory. Oh hello.
- Collins: Who're you? How did you get in here?
- The Doctor: Through the window. I understood the property was for sale. No?
- Collins: Ahh, you're not fooling me, Sir. You came with Dr. Warlock didn't you?
- The Doctor: Did we?
- Collins: He asked you to scout around while he kept His Nibs busy. Listen, if you're a friend of Dr Warlock's, tell him to watch out.
- Sarah Jane Smith: Watch out for what?
- Collins: The Egyptian. There's no knowing what he might do, he's got the temper of The Devil himself.
- The Doctor: Egyptian, eh? Is this where he keeps his relatives?
- Collins: It's no joke, Sir. He's only been here a few days but, I wouldn't be staying but, well, situations aren't easy to find at my age.
- The Doctor: What are you afraid of?
- Sarah Jane Smith: He locked this wing. He didn't know there was a second key. If he were to find me along here, let alone you two, he'd... he'd go stark raving mad, Sir.
- The Doctor: I see. In that case we'd better leave.
- Collins: Oh not this way Sir, better go the way you came. He might see you.
- The Doctor: As you wish.
- Collins: Uh, and remember to tell Dr. Warlock what I said, Sir.
- The Doctor: Don't worry, I'll remember.
- Laurence Scarman: [astounded at the Doctor recognizing his radio telescope invention] How could you possibly know that?
- The Doctor: Well, you see, Mr. Scarman, I have the advantage of being slightly ahead of you. Sometimes behind you, but normally ahead of you.
- Laurence Scarman: I see.
- The Doctor: I'm sure you don't, but it's very nice of you to try."
- Sarah Jane Smith: Hey Doctor, Doctor. Look what I found.
- The Doctor: Hello Vicki.
- Sarah Jane Smith: What?
- The Doctor: Hmm? Where did you get that dress?
- Sarah Jane Smith: I just told you. I found it, back there in the wardrobe. Why, don't you like it?
- The Doctor: Yes, yes I always did. Victoria wore it. She travelled with me for a time.
- Sarah Jane Smith: Well as long as Albert didn't wear it.
- [Giggles]
- Sarah Jane Smith: Oh come on Doctor, that's worth a smile, surely. What's the matter? You should be glad to be going home.
- The Doctor: The Earth isn't my home, Sarah. I'm a Timelord.
- Sarah Jane Smith: Ohh I know you're a Timelord.
- The Doctor: You don't understand the implications. I'm not a human being. I walk in eternity.
- Sarah Jane Smith: What's that supposed to mean?
- The Doctor: It means I've lived for something like 750 years.
- Sarah Jane Smith: Oh so you're middle aged.
- The Doctor: Yes. It's about time I found something better to do than run around after The Brigadier.
- Sarah Jane Smith: Oh come on, if you're tired of being UNIT's scientific advisor you could always resign.
- Laurence Scarman: Well in view of what you've told me, I'm going to fetch the police.
- The Doctor: No. This is much too grave a matter for the police, Mr Scarman.
- Laurence Scarman: Too grave?
- The Doctor: Yes. They'd only hamper my investigation.
- Laurence Scarman: Your investigation?
- The Doctor: Yes. Why do you think I'm here? Something's interfering with time, Mr Scarman. And time is MY business.
- Laurence Scarman: Who are you ?
