K-MASTER: You will obey me.

PERI: No.

K-MASTER: I am the Master!

PERI: So what? I'm Perpugilliam Brown and I can shout just as loud as you can.

MEL: How could they? It's obscene.

DOCTOR: Not to a Vervoid.

MEL: You can't justify it. It's just-

DOCTOR: It's a matter of perspective, Mel. In your house in Pease Pottage, you had a large garden. What did you do with the plants and weeds you uprooted?

MEL: Put them on a compost heap.

DOCTOR: They're obeying instinct, like migrating birds or salmon swimming relentlessly upstream to spawn even though they may die. A compulsive following of the life cycle. Come on, Mel.

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.)

“Great chunks of my past, detaching themselves like melting icebergs.”

“Great name, Mundy Flynn. You should marry Ruby. Then you'd be Mundy Sunday. Go on, get married, I'd laugh every day.”

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.

“I know we see so much death Nyssa, but... there's an invincibility I feel around the Doctor, even after Adric, though I'll admit I lost it for a while. I didn't mean to bring him up, I- I'm kinda hoping you can't hear me. I can't hear you at least.”

SKAGRA: Take over the universe? How childish. Who could possibly want to take over the universe?

DOCTOR: Exactly. That's what I keep telling people. It's a troublesome place, difficult to administer. And as a piece of real estate, it's worthless, because by definition there'd be no one to sell it to.

“Is that pettiness, or attention to detail? I'm an artist Doctor, an auteur of misery and death, and this is my finest work.”

DOCTOR: So, what are you going to do while I pop over and get her?

TEGAN: You must be kidding, you're not going in there without me.

DOCTOR: I don't want to argue with you Tegan.

TEGAN: Then don't. You can't leave me behind, we're in this together.

DOCTOR: You realise the danger?

TEGAN: Of course I do! And I get why you're worried, okay? But what happened to Adric, isn't going to happen to me.

DOCTOR: You don't know that.

TEGAN: I do know that I'm not staying here while you and Nyssa are in danger. So unless you plan on locking me up-

DOCTOR: Alright, alright.

POLICEMAN: Sir, ma'am, go back to your vehicle.

GRACE: What? Stop! He's er, he's British.

DOCTOR: Yes, I suppose I am. Jelly baby, officer?

POLICEMAN: Jelly baby?

GRACE: Just take it.

(The policeman takes a sweet and sniffs it while the Doctor makes lip-smacking noises. When he bites into it, the Doctor takes his gun and points it at his own chest.)

DOCTOR: Now, would you stand aside before I shoot myself.

Turlough shook his head. 'Is it any wonder I was so keen to leave this ridiculous country behind? Everyone here is completely barking mad.'

'Oh, you think so, do you, sir?' The mouse-like man drew himself up to his full height and glared at the schoolboy.

'I do actually, yes,' Turlough jeered. 'And as for all that sucking up you all do to royalty and the nobility and the like, I've never heard such outdated nonsense!'

DOCTOR: Tegan, sometimes I wonder how well I'd get on without you

TEGAN: Thank You

DOCTOR: Probably quite alright, all things considered

“I had the strangest dream the other night. I dreamt that we were on a case, another infestation of infernal invaders, and after applying your deductive powers and bearding them in their lair, you'd been caught by the nasties. I forget what they looked like, all a bit vague, that's dreams. Yet one thing was clear, clear as a bell, they were going to kill you, and they were gloating about it the way nasties always do. Somehow they knew that I had promised to look after you, and they were taunting me. Laughing in me face. And when I woke up I thought- if they did carry out their ghastly threat, if you were to suffer and expire at their hands, the last thought to pass through your mind would be 'Where's Henry? He said he'd be here.' And I'd realised that I'd rather face a thousand nasties than to have you think that of me.”
