- The Doctor: [looking at the pyramid] Hmm! It's a pity we didn't bring a ladder with us. We might be able to see what's on the top.
- Ian Chesterton: Well, it isn't Nelson.
- The Doctor: No. No pity.
- Ian Chesterton: You've ruined it. It was my Coal Hill School tie. You've just...
- The Doctor: Saved your life. You were about to have a wash in there, weren't you? Or probably drink some of it? We very nearly had the remnants of a Coal Hill School teacher in there, instead of his wretched old, ragged old tie.
- The Doctor: I wouldn't have thought it possible, but somehow we've materialised, for a split second of time, and been imprisoned in some kind of force. I simply can't break its hold. Somewhere, somehow, we're being slowly dragged down.
- Ian Chesterton: Dragged down? To what?
- Ian Chesterton: What's happening, Doctor? What's happening?
- The Doctor: We seem to be caught. Trapped somehow. This is some strange phenomena. There's no power in the ship. It's useless.
- Ian Chesterton: Well, come on then, Doctor.
- [pause]
- Ian Chesterton: Ah! How do we open the doors? We have no power.
- The Doctor: Dear, dear, dear, dear, dear. Hmm... It's one thing after another.
- Ian Chesterton: Hmm?
- The Doctor: Yes, well, I uh... I uh... I didn't want to uh...
- [hands him an small metal object]
- The Doctor: This is not merely a decorative object. Come along. Come along.
- Barbara Wright: Vicki? Here, take these. You'll feel much better.
- [hands Vicki a sedative]
- Vicki: What is it?
- Barbara Wright: Oh, it's just something to make you sleep.
- Vicki: May I see the container?
- [Barbara hands her the container]
- Barbara Wright: Any aches or pains?
- Vicki: No, I didn't hurt myself. My ears still sting a bit, but that's all.
- Barbara Wright: Well, have you decided yet whether to take the prescribed dose?
- Vicki: It looks a bit medieval.
- Barbara Wright: What do you mean?
- Vicki: Well, you wouldn't like it if I tried to stick leeches all over you, would you? And I mean, it boils down to the same thing. They might have taken these in your time, but that doesn't mean...
- Barbara Wright: Now, wait a minute. You can't blame my generation for everything, and those pills belong to the Doctor.
- Vicki: He must've picked them up on his travels then, 'cause I've never seen Aspirin before.
- Barbara Wright: Oh, so you studied medicine at school, did you.
- Vicki: Yes, of course, I did. Didn't you teach it?
- Barbara Wright: No. We worked upwards from the three R's.
- Vicki: Hmm?
- Barbara Wright: Reading, writing, 'rithmetic.
- Vicki: Oh, it was a nursery school?
- Barbara Wright: It was not!
- Vicki: Oh! I wish I'd gone to your school. We had to take a certificate of education in medicine, physics, chemistry...
- Barbara Wright: Now, wait a minute. How old were you?
- Vicki: Well, I was ten when I took those, and then...
- Barbara Wright: Ten! What did you do in your time? Live in the classroom?
- Vicki: Live in the what?
- Barbara Wright: Classroom.
- [Vicki still looks confused]
- Barbara Wright: Lecture hall. How long did you study?
- Vicki: Almost an hour a week. We had these machines, you see, and we all...
- Barbara Wright: All right. Now, look, you don't think there's anything wrong with those pills, now do you?
- Vicki: No.
- Barbara Wright: Well, why don't you just pander to my old-fashioned, medieval superstitions and take them for me?
- Vicki: Well...
- Barbara Wright: After all, it would save me having to put make up on and a mask and dance around a fire in order to get rid of evil spirits.
- Vicki: All right.
- Barbara Wright: Good.
- The Doctor: Well, well, well. That is remarkable.
- [chuckles]
- The Doctor: Gracious. During all my travels, I don't think I've ever come across this. Magical. Isn't it extraordinary? I say, are you there Chesterton? Chesterton. What are you doing, dear boy? Fiddling and gaping over there. Come over here and learn something.
- Barbara Wright: Well, it's the things we don't understand that frightens us. I'm sure there is a perfectly simple explanation. I'm just letting my imag...
- Ian Chesterton: Doctor! There! There's something in there. I saw light. It broke the surface.
- The Doctor: Light? Is it a reflection from a planet?
- Ian Chesterton: No, no, it was in there. I saw something in there, I tell you.
- The Doctor: Now, my young man, if this is your idea of revenge for that tie, then I say, I think it's a pretty poor effort.
- Ian Chesterton: Doctor, this is not revenge.
- The Doctor: Listen, we came here to find the source of interference. Now, I suggest we keep our minds on this subject. You're rambling on. come along!
- Ian Chesterton: Doctor, can't there just be something wrong with the TARDIS?
- The Doctor: Wrong? My boy, we've been dragged off our course. The question is, is it some natural phenomena, or is it intelligent, deliberate, or for a purpose? Hmm?
