The Doctor: [reassuring Victoria, who misses her father, with recollections of his own family] I have to really want to - to bring them back in front of my eyes. The rest of the time they... they sleep in my mind, and I forget.
[At her expression]
The Doctor: And so will you. Oh, yes, you will. You'll find there's so much else to think about, to remember. Our lives are different to anybody else's. That's the exciting thing! Because nobody in the universe can do what we're doing. You must get some sleep, and let this poor old man stay awake.
The Doctor: The power cable generated an electrical field and confused their tiny metal minds. You might almost say they've had a complete "metal" breakdown.
Jamie: [groans] Oooh!
The Doctor: I'm so sorry, Jamie.
Cyber Controller: You belong to us. You shall be like us.
Cyber Controller: We will survive. We will survive.
Cyber Controller: Enough. These humanoids are not like us. They still have fear. Place the Cybermats on the runway. Cybermats will attack.
The Doctor: Oh! I'm on your side, remember? Hey, why didn't you wake me? I should have been on watch half an hour ago.
Victoria: I thought you should rest.
The Doctor: Why me?
Victoria: No reason, really.
The Doctor: Oh, I think I know. Is it because I'm...
Victoria: Well, if you are four hundred and fifty years old, you need a great deal of sleep.
The Doctor: Well, that's very considerate of you, Victoria. But, between you and me, I'm really quite lively actually - all things being considered. Are you happy with us, Victoria?
Victoria: Yes, I am. At least, I would be if my father were here.
The Doctor: Yes, I know, I know.
Victoria: I wonder what he would have thought if he could see me now.
The Doctor: You miss him very much, don't you?
Victoria: It's only when I close my eyes. I can still see him standing there. Before those horrible Dalek creatures came to the house. He was a very kind man. I shall never forget him. Never.
The Doctor: No, of course you won't. But, you know, the memory of him won't always be a sad one.
Victoria: I think it will. You can't understand, being so ancient.
The Doctor: Eh?
Victoria: I mean old.
The Doctor: Oh.
Victoria: You probably can't remember your family.
The Doctor: Oh, yes, I can, when I want to, and that's the point really.
The Doctor: Jamie, Victoria, Callum, wake up! Wake up!
Victoria: What is it?
The Doctor: [a Cybermat is crawling up Jim Callum's chest] Callum, Callum.
Victoria: What are those terrible things?
The Doctor: Don't move, Callum. Don't move.
[the Doctor knocks it onto the floor]
The Doctor: Now, get back to the controls, all of you. Steady. Don't make any sudden movements. Parry, Parry, wake up, Parry. Wake up. Wake up. Don't panic. Come back with us. Steady. Now, we'll all go in the other room and lock them out.
Victoria: [screaming] Aagh!
Jim Callum: Let's get out of here. The main doors.
[runs over to the main doors where another Cybermat is coming]
Jim Callum: No, look!
Victoria: Oh! Oh, Doctor, we're trapped!
The Doctor: Back against the controls, everybody! Here.
[picks up a power cable]
The Doctor: Give me a hand, quick!
Professor Parry: The what?
The Doctor: Lay this down on the ground. Come on!
Jamie: We can't move it, Doctor!
The Doctor: Come on!
Jim Callum: Well, let's blast the filthy things!
[begins shooting at them]
The Doctor: You're wasting your time. There are too many of them! Now, do what I say. Come back!
[the Doctor switches the power on and the Cybermats begin to die]
The Doctor: There you are, you see?
Professor Parry: What are those creatures?
The Doctor: Well, they're... They're a form of metallic life. They home on human brainwaves and attack.
Victoria: Urgh! Are they safe now?
The Doctor: Oh, yes, quite safe now.
Victoria: What about Klieg and Kaftan? They'll probably attack them as well.
Professor Parry: The testing room.
The Doctor: Now, come on. Mind your feet.
Eric Klieg: Most ingenious, Doctor. Now, let's see what you can do against this.
[holds up a Cyberman X-ray gun]
Jamie: Watch out, Doctor!
