TEGAN: I can't go back there Doctor, you can't let me go back there.

DOCTOR: I won't.

ADRIC: The Doctor can find a way out of this Tegan, you know that, he'll never let any of us down.

DOCTOR: You must've injected me with something on the way in! No, no, no, I'd feel it in my veins, my veins aren't where I feel it.

ADRIC: Feel what, Doctor?

DOCTOR: Pain.

DOCTOR: It’s a maternity suite.

TURLOUGH: A maternity suite?

DOCTOR: For babies. They do have babies on your planet, don’t they? I’m not gonna have to explain where they come from?

FOURTH DOCTOR: I'm essentially a pacifist. Although that does sometimes involve blowing things up.

DOCTOR: Mind over matter. Or more accurately, I have a mind and you don’t matter.

DOCTOR: Blaming the Universe is the only way I can get out of bed in the morning.

TURLOUGH: I tried to get back to the TARDIS, and I used that TARDIS tracker you gave me.

DOCTOR: Yes, yes –

TURLOUGH: And it pointed in three directions at once. I assumed it was just faulty.

DOCTOR: I built it myself.

TURLOUGH: Exactly

DOCTOR: You see, women... they're not exactly my area. Apart from Tegan, and Nyssa. But they were friends, I was responsible for them -- that wasn't the same.

TURLOUGH: Good friends.

DOCTOR: Then there was Sarah-Jane, of course, and Jo. And Romana, both of her. Zoe and Victoria, Dodo and Vicki, and.. Barbara.

TURLOUGH: And Susan?

DOCTOR: Ah, well of course, she was my granddaughter. Sometimes I feel very old.

TURLOUGH: Tegan, no!

(The Doctor floats to the surface, face down.)

TEGAN: Doctor!

TURLOUGH: There's nothing we can do.

TEGAN: We can't just leave him.

TURLOUGH: Face it, Tegan. He's drowned.

(The Doctor sinks below the surface again.)

TURLOUGH: If ever you had to kill someone, could you do it? Could you?

TEGAN: No. I don't know. If it was important, to save my friend, to defend myself.

TURLOUGH: But cold-bloodedly?

TEGAN: You're weird, Turlough.

ROMANA: How did you know?

DOCTOR: Oh, knowing's easy. Everyone does that ad nauseam. I just sort of hope.

SECOND DOCTOR: If only I could find my recorder, I could play you a little something to pass the time.

BRIGADIER: We must be thankful for small mercies.

DOCTOR: Goodbye, Jamie.

JAMIE: I won't forget you, you know.

DOCTOR: I won't forget you. Don't go blundering into too much trouble, will you?

JAMIE: Oh, you're a fine one to talk.

(A metallic clang echoes loudly.)

DOCTOR: Great jumping gobstoppers! What's that?

DOCTOR: Oh, my giddy aunt.

JAMIE: We're stuck here in this lift now!

DOCTOR: No, no it's the lift that's stuck, not us. Look.

(The Doctor points up at a maintenance hatch on the ceiling)

JAMIE: Hey, where does that lead to?

DOCTOR: Out into the lift shaft, I imagine. Quickly, on me back.

(The Doctor leans down)

JAMIE: You know something?

DOCTOR: Mmhmm?

JAMIE: You're a clever wee chappie.

DOCTOR: I hate computers and refuse to be bullied by them!

JAMIE: Well it's simple isn't it? All we've got to do is dig a tunnel through from here to the borehole and catch the seed device thing on it's way down. Well, it was just an idea.

DOCTOR: But Jamie, it's a brilliant idea! It's so simple only you could have thought of it.

JAMIE: Oh. Eh?

DOCTOR: An unintelligent enemy is far less dangerous than an intelligent one, Jamie. Just act stupid. Do you think you can manage that?

JAMIE: Doctor, come on, will ye? The whole place is going to blow up.

DOCTOR: Oh, it's quite all right, Jamie. The planet is quite safe. There's just going to be a localised volcanic eruption. It'll only affect the island.

JAMIE: Maybe so, but we happen to be on the island.

DOCTOR: Oh, my word!

JAMIE: Have you thought up some clever plan, Doctor?

DOCTOR: Yes, Jamie, I believe I have.

JAMIE: What are you going to do?

DOCTOR: Bung a rock at it.

DOCTOR: Victoria, I think this is one of those instances where discretion is the better part of valour. Jamie has an idea. Come along.

DOCTOR: You look very nice in that dress, Victoria.

VICTORIA: Thank you. Don't you think it's a bit--

DOCTOR: A bit short? Oh, I shouldn't worry about that. Look at Jamie's.

DOCTOR: Well, this is gay!
