Sarah Jane. You came to say goodbye.
The collision of the moon and Earth will release the Xylok from beneath the planet's crust, where it has been buried for 60 million years.
You're going to kill thousands of people!
The Xylok are a crystalline lifeform. We crashed here as what you would call a meteorite, but beneath the Earth, our crystals have regrown and become strong again, but nevertheless remain trapped.
You're still part of the original crystal, you're still in contact with it!
The release of the Xylok is my purpose. You gave me the chance to fulfil it, the chance to plan.
All this time... you used me! Mr Smith, you're evil!
No - effective. We will do so much more than the human race. The universe is served much better by our survival.
Any race thinking it's better than another, that's evil, Mr Smith!
So what have you done with Clyde?
[teleports Clyde back to Earth] Am I not merciful?
[points lasergun at them] You made all this possible, Sarah Jane. I owe you the mercy of a quick death.
But what about all the other people, don't they deserve mercy? You've been here millions of years, you've seen us evolve! Don't we matter to you?
Maybe you could change your purpose?
No, I told you, Sarah Jane, we all have a purpose. Yours is to die, so that the Xylok will live. After all, what life do you have, alone in your attic?
Alone?! You think I'm alone?! You think I'm defenceless?! Well, meet my dog! K-9! Protect me!
K9K-9
Affirmative, mistress! Activating defence mode!
[Sarah Jane pulls out a phone and calls Mr Smith]
Well, actually, for once, it's not you I need, it's K-9.
That's the one, patch me through Mr Smith.
Boosting telephone signal, connecting now.
K9K-9
Greetings Mistress!
K9K-9
Affirmative, Mistress!
K-9, you're coming home, for good this time...! K-9, I'm in a spaceship under a beach on the south coast. The spaceship needs a blackhole, reckon you can help?
K9K-9
Affirmative Mistress. Spaceship? Can you read me...? I am currently generating a shield around the blackhole.
SShip
If you send me your coordinates, I can absorb the energy.
K9K-9
Sending coordinates now! My Mission is completed.
[K-9 teleported from the safe, in a flash of yellow light re-appearing in the attic]
K9K-9
Greetings, Mr Smith.
It's good to see you, K-9... will you be staying here now?
[sarcastically] Oh, good.
[Rani, Luke and Clyde are sitting in the attic after spying on Sarah Jane]
What are you all doing here!
We have a test coming up-
And Luke's helping us revise.
[Sarah Jane looks over to Mr Smith who is still on]
Why is Mr Smith still on?
Sarah Jane's car is now outside the house.
Big Mouth! You did that on purpose.
K-9 What's going on here?
K9K-9
I have been told to withhold information.
[Rani and Clyde are smug]
What exactly was that information?
K9K-9
I was told by Mistress Rani to not tell you that you were being followed.
Here we go K-9, questions! Now, just relay your answers into this [points to earpiece]
K9K-9
Relaying answers is unethical.
You said a test was one human demonstrating interlectual superiority over others. I have bought a super computer into school. It's pretty smart, wouldn't you say?!
[K-9 takes a moment to consider Clyde's argument]
Now, Sarah Jane, what was your son's name?
Luke! He's called Luke...And the computer's called Mr Smith!
Calling Luke and Mr Smith! This is the Doctor! [Luke looks up from where he's sitting] Come on, shake a leg!
Oh, she's fine and dandy!
Now, Mr Smith, I want you to harness the Rift power, and loop it round the TARDIS - You got that?
I regret I will need remote access to TARDIS basecode numerals.
[winces] Oh blimey, that's gonna take a while...
No, no! Let me! [runs up to the monitor] K-9! Out you come!
[K-9 materialises in the attic]
K9K-9
Affirmative, Mistress!
[laughs delightedly] Good dog! K-9, give Mr Smith the basecode!
K9K-9
Master. [connects to Mr Smith] TARDIS basecode now being transferred. The process is simple!
