Sometimes my brilliance astonishes even me.
“The Invisible Enemy” · Season 15, Episode 2
In this episode: Fourth Doctor (8), Leela (7), K-9 (1)
There was a sort of glow all around you!
There was? Well, a kind of St. Elmo's fire; it happens at sea.
St. Elmo's?
Yes, it causes a sort of halo effect around the masts of ships.
Halo?
Why do you keep repeating everything I say? You're not a parrot, are you?
Parrot?
[incredulous] Yes. A parrot's a bird that repeats things. Move over.
[sarcastic] Move over!
That's it!
[Bang! From inside the console]
I thought you said there was nothing wrong!
Well, there isn't anything wrong. Well, there isn't anything important wrong, but I've got to check, haven't I?
I can still feel it.
Come on, old thing. come on.
[Tendrils of energy leave the TARDIS console and enter the Doctor's eyes. He sways]
Contact has been made.
[The Doctor collapses]
I said, 'I'm perfectly alright, thank you, Lalee'..
But my name is 'Leela'.
I know your name. "Leela"...
What happened?!
I must have had a bot of a shick...
[Finding a disgusting bit of dangling brain matter]
Eugh, what's that?
That is why my brain is so much superior to yours!
What do you know about brains, anyway?
All right, all right, don't get excited!
I'll get excited if I want to! It's my brain! I'll tell you something about brains-- do you want to know something?
Not much.
I'll tell you anyway. Someone once tried to build a machine as efficient as the brain. The only problem was, it would have had to be bigger than London-- do you remember London?-- and powered by the entire European grid. And that was just a human brain. Mine's much more complex.
[Slapping dangling bits of his brain material together in desperation] OW!
What did you do?
I think I told them my liver was disintegrating, I think.
[finding something strange in his brain] Who are you?
I am the Nucleus.
You're trespassing, you know. Treading on my unconscious, affecting my metabol... Nucleus of what?
The Nucleus of the Swarm.
Oh. Oh, I see. Why did you choose my brain?
Because of your intelligence.
Oh well, I can understand that, but you realise you have no right-
I have every right! It is the right of every creature across the universe to survive, multiply and perpetuate its species. How else does the predator exist? We are all predators, Doctor. We kill, we devour to live! Survival is all, you agree?
Oh yes, I do, I do. And on your argument - I have the perfect right to dispose of you.
Don't worry, Doctor. I found the answer: knife them in the neck!
Hahahaha! That was a good idea of mine, K-9, to blow it up!
Affirmative!
What do you mean, it was a good idea of yours? It was my idea!
What was?
To blow it up!
Then you should be feeling very happy.
