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.
