The Sarah Jane Adventures s01e10 Episode Script
The Lost Boy: Part 2
MILLY: 'Tracy Beaker, shut your big, fat gob!' # I can make my world come true All my dreams will see my through # And the fight won't get me down No! No! # My dreams will turn things All around # With a smile upon my face I can see a better place # It doesn't matter What may come my way No! No! # Believe me now I will win some day.
# It's been five months since we saw Ashley.
'I have a comprehensive genetic match.
' What? 'Luke and Ashley Stafford are the same person.
' Why can't I remember them? Ashley, thank God.
Children have no place in my life.
You don't mean that.
Go home.
Mitre.
Who developed it? You told her about Mitre? Those headsets take the latent raw psychic ability all humans possess to move objects with the power of thought, and directs it.
Mr Smith, are you asking me to go back to Pharos and steal a headset? It would be of great assistance.
We'll see about that.
It's Luke with the pair who reckon he's their kid.
I think it's a fake.
Xylos, are you there? You're right Clyde, I faked it.
EVIL GROANING You're Slitheen? Aagh! HA HA HA HA HA HA HA HA! BUZZING BANGING NOISE BUZZING BUZZING RADIO CRACKLE SIREN BLARES 'Intruder! Perimeter defences have been armed.
'Any attempt to escape may result in death.
'You have been warned!' Noted.
Hope that didn't sting too much.
GROANING 'This is Clyde.
If you want me - and I don't blame you - leave me your number, specially if you're cute.
Clyde! What's going on? Ring me back! Where are you? Hello, hello! Anyone? Where am I? Where am I? Just a clue? At least I'm still alive.
I think.
No Mrs Langer, I haven't seen him.
Don't worry, I'm sure he's stayed at a mate's.
If I see him, I'll tell him to ring you, OK? Something wrong? Clyde's not answering and he didn't go home last night.
When did you last see him? Lunchtime yesterday.
He skipped school to see Luke.
He rang me later.
He says he doesn't think they're really Luke's parents.
I know I'm new to this X-Files stuff, but isn't it more likely that Luke is a normal boy who lost his memory rather than Frankenstein Junior made by these aliens, The Bean.
The Bane, and Clyde thought he had proof that these people are fakes.
What? Fake parents or fake people? Maybe both.
What if they've done something to Clyde? His mother must be going out of her mind.
I've got to go and look for him.
No you don't.
I'm part of this now.
I'm coming with you.
If I was an alien bent on invasion, I'd choose a palace rather than this place.
They're not in.
Come on.
Where? If the house is empty, it's our chance to find out about them.
Maria! Come on Dad, there may be a window round the back.
Housebreaking, great! Your mother was right about you hanging out with Sarah Jane.
Just keep quiet, Dad.
And start looking.
What are we looking for? Who they are, or what they've done with Luke and Clyde.
Who they are, what they've done with Luke Oh! They've skinned someone! They're cannibals! They're not cannibals.
They're Slitheen.
Where are you taking me? "Where are you taking me? Why take revenge?" Why are children full of stupid questions? You're a child.
I'm Slitheen, you will give me my revenge.
I don't want to do that.
Should be doing this? The Xylok said we should wait? Are you questioning my authority? You'd trust a Xylok, Dak Fex Fize? You're as thick as a human.
What's a Xylok? See what I mean? THEY LAUGH This is looking distinctly un-cool, Clyde.
No way in and no way out and no-one to tell me what the hell's going on! 'I can tell you.
' Mr Smith? Where are you? 'Surely the relevant question, Clyde, is where are you?' Hold on, you've gone bad.
You zapped me.
'I haven't gone bad, I'm fulfilling my purpose.
' Which is to zap me into where, exactly? 'This will have to wait, but we can chat later, 'it will pass the last few hours before you all die.
' Before what? Mr Smith, I need you! 'You called me, Sarah Jane.
' Holy Joe! Mr Smith's going to kill us, and I'm inside him! I got the headset.
'It will be of great assistance.
' No! Sarah Jane! Can you hear me? He's the bad guy! 'I will let you have my conclusion in due course.
'Assessing.
' This does not sound good at all.
You've got to do something.
Think! You're inside a computer what can you do? We have to tell Sarah Jane.
That you've got a kitten to replace the boy she kidnapped? I don't remember giving you a key.
You didn't lock the door.
Lucky I came by.
Computer's making a noise.
I'd better look at it.
Would you pop to the shop, get some teabags? Sure.
Won't be long.
Will she be OK with the child-snatching maniac around? Yes! She can look after herself.
Sarah Jane's not a child-snatcher, or a maniac.
Come on.
What are you doing? More stupid questions.
I told you, I don't want you here.
They're not Luke's parents.
They're Slitheen! Hello Nathan.
What are you doing here on a Saturday afternoon? Aaagh! Aaagh! Aaaagh! Go! He'll be out cold for hours, by then it will all be over.
You can't just go out and leave things on, Alan.
It's a fire hazard.
Look at it.
It's not supposed to do that.
Well, I can't hang around.
Ivan's taking me shopping.
Oh, make sure you keep Maria away from her over the road.
Sooner she's locked up, the better! Yeah.
Sure.
It's always your trouble, Alan.
Work.
Don't worry, let myself out.
Mr Smith, we need you.
'You called, Sarah Jane.
' Do you know of any Slitheen activity on Earth? 'Slitheen? Why do you ask?' You got it wrong! They weren't Luke's parents.
They're Slitheen! 'Ha ha ha ha ha ha ha!' Mr Smith? 'Humans.
So inevitably predictable.
' Get out now! Mr Smith is one of the bad guys! Don't be ridiculous.
Who told you those people were Luke's parents? Mr Smith? What's going on? 'I have a Purpose.
It must be fulfilled.
'The Slitheen have been useful.
'And so have you.
But you are no longer required.
' Get down! 'Ha ha ha ha ha ha ha ha ha!' Let's get out of here.
I trusted him with my life, with the whole planet.
What's happened to him? Some kind of computer virus? Maybe Clyde can tell us.
Clyde? Yeah.
Come on.
'Now this is refreshingly unpredictable.
'Communicating with Mr Jackson's computer.
'Well done, Clyde.
You're not as stupid as you pretend, are you?' When it comes to pretending, you take the biscuit.
We thought you were on our side.
'I'm a Xylok.
I'm not on anybody's side.
'I have my Purpose.
'As for your interference, it is of minimal inconvenience.
'Sarah Jane can't stop me achieving that Purpose.
'And soon you will play your part in it.
'But now your communications are terminated.
' COMPUTER SOUNDS CRASH It wasn't on-line messaging.
He was just there.
He'd hacked in? I've never seen anything like it.
We have to find out what's going on.
Does Mr Smith has anything to do with Luke and the Slitheen? He must have.
But how? Could Mr Smith have some connection with the Slitheen? Where did he come from? The biggest volcanic eruption civilization has ever seen.
researching volcanic activity, a geologist friend sent me a crystal from the site of Krakatoa.
The crystal had become a curiosity among geologists.
They'd never seen anything like it.
Neither had I.
But they didn't see what I did.
It was as if the crystal was communicating with my laptop and using it to communicate with me.
It was a cell from a space craft that crashed millions of years ago.
Its computing power, its knowledge, it was phenomenal.
It told me amazing things.
It said it could help track alien life coming to Earth, could protect the Earth, but our technology was limited.
And so it designed, and it created .
.
Mr Smith.
So why, after all this time, turn against you? We'll work it out as we go.
We have to find Luke.
I gave him to the Slitheen.
Whatever they want, I have to get him back.
They want to use him to invade? The Slitheen don't invade.
They're not a race.
They're scavengers.
It's Only Fools and Horses with claws.
They're dealers, they sell anything and in some parts, telekinetic energy fetches a huge price.
They could have got plans for the energizer from across the galaxy, had it built at the Pharos.
I knew I didn't care for Nathan.
Telekinetic energy? Moving things with your mind? Luke's mind.
Created by the Bane.
The most incredible mind on the planet.
If the Slitheen harness it, Luke's telekinetic powers could be massive.
So they bottle it and sell it? What happens to Luke? If they take it all - and they never leave anything behind that they can sell - Luke will die.
We have to find him, and I know where to look! Have you got any vinegar? No, we're all out.
Then we may have to stop off at a chip shop.
Go! MANIC LAUGHTER Whatever you want, I'll fight you.
Love it.
The more brain activity, the faster we harvest the telekinetic energy.
And we want it all.
Every spark from every synapse.
Until you're dead.
EVIL GIGGLING We're all set here.
Then let's energize! It's working! He's filled up two storage tanks already.
I've never seen so much energy, we're going to be rich! He's a telekinetic power station! We'll have a supernova of a holiday this year, Bloorm Vungah Bart! Oh, Dak Fex Fize! Look out, he's overloading the system! What's happening? Bloorm Vungah Bart! He's using his own telekinetic energy! He's getting away! Nazdracks to the profit.
I'll have my revenge warm and dripping! I'm coming, Luke! I can smell your fear, Luke.
Yes, Luke run, run.
Never mind phasers or photon torpedoes.
Never mind Arnie's Uzi 9 mm.
We're taking on aliens with vinegar? It's acetic acid.
Slitheen are calcium.
Calcium and acetic acid don't mix.
Trust me.
Sure, why not? Aah, revenge at last, Luke, I'm going to enjoy this kill.
This is for my father! You slippery the same blood that made you.
What happened here? With a little luck, Luke did.
Oh, oh, oh! Oh, my head! Oh, my I'm armed.
What's going on? What have you done with my son? The misbehaving little brat? Back on Raxacoricofallapatorius, we'd spank him with a Bartleboigle tree.
We're not there.
Where is he? He got away.
That doesn't matter.
Leave her alone! You killed my father, Sarah Jane Smith.
At the school.
Use your sonic device open the door, open the door! Aaaaagh! You were the child? I didn't want you to die.
But you were going to kill our planet.
Get away from my daughter, you overgrown newt! No.
You drop your weapon.
Or she dies.
Now let her go, frog face.
Dad!.
What now? Now we contact the Xylok.
Get this deal back on the rails.
Once we've found the youngling again.
The Xylok? You know him as Mr Smith.
Why would Mr Smith make a deal with you? He contacted us.
He said he had seen what you did to my family.
He wanted to help us get revenge.
If that was what he wanted, why did he send me here to find the energizer? He sent you here? It's all been part of his plan.
He brought you to Earth to build the telekinetic energizer.
He told me to come here looking for it.
I don't understand.
Neither do I.
Not yet.
But the last part of his plan has just fallen into place.
Mr Smith knew Luke would escape and he knew that, when he did, he would run straight back to my house.
Right back to him.
Sarah Jane! Sarah Jane! 'Luke! Up here, Luke.
' What does Mr Smith want with Luke? Luke.
And the telekinetic energizer headset.
Mr Smith had me steal one of them, the prototype's in my attic.
I don't care.
I'll deal with the Xylok later.
We don't need him for revenge! If you kill us, you won't stop Mr Smith, or get off this planet.
Save your breath.
You'll need it for screaming.
Get off! Let me go! She's my kill! A claw for a claw! When you're older, you'll learn not to make snap decisions.
Now what do you mean? Something Mr Smith said about the energizer.
With the right mind, it could destroy worlds.
He meant Luke's mind.
I think he's planning to destroy the Earth.
'Come in, Luke.
' Where's Sarah Jane? 'She left something for you.
'Put it on, Luke.
' No.
'There really isn't time to argue.
' Clyde? 'Put it on or I will kill him.
' But you're 'Running out of time and patience.
'Put the headset on.
Now! 'That's more like it.
'At last, we can begin.
' ZAPPING NOISE Aaaaaagh! URGENT BLEEPING What's that? MITRE it's gone on-line.
Mr Smith.
He's using the headset on Luke.
Massive telekinetic levels.
They're off the scale.
EXPLOSION What the? The moon! It's moving! It's not possible.
Luke isn't possible.
Mr Smith isn't possible.
But they're bringing the moon crashing down on Earth.
But it's a quarter of a million miles away.
We'll be dead long before it hits us.
The gravitational effect will tear the planet apart.
It's happening.
At least I'll be able to tell my family you're dead, Sarah Jane Smith.
I'm teleporting back to the ship.
You're not! You're as much to blame as Mr Smith! You're staying.
Your ship would be torn apart by gravitational disturbance.
On the other hand, if you help me, we might all just have one chance to survive.
I need you to destroy Mr Smith.
'Give me more kinetic.
Let the universe witness the power.
'Ha ha ha ha ha ha!' 'The moon is heading to earth, causing 'spontaneous forest fires, indeed we have had reports of avalanche, 'freak storms and indeed tidal waves.
'As this continues, it becomes more.
.
' PHONE RINGS Chrissie? Alan, where are you? It's the end of the world! Chrissie, calm down.
Calm down!? Alan, I need to be with you, you and Maria Alan! Chrissie? Chrissie.
The phone line's gone.
We're almost out of time, Alan.
I get paid by companies to block cyber-threats.
I understand viruses, how they work.
But Mr Smith he's more than a computer.
Dad, you're our only chance.
Well, then this is my best shot.
The FBI have stopped a cyber-terrorist from using this to destroy the entire international banking network.
How did you get hold of it? You're not the only one with unorthodox contacts.
Time to show me how this works.
The United Nations is in emergency session to discuss this apocalyptic crisis.
Luke! 'Sarah Jane.
You came to say goodbye.
' Why are you doing this? 'The collision will release the Xylok from beneath the planet's crust 'where it has been buried for 60 million years.
' You're going to kill billions.
'The Xylok are a crystalline life form.
'We crashed here as a meteorite.
'But buried beneath the Earth, 'our crystals have become strong again, but remain trapped.
' The original crystal You're 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 much more than the human race.
'The universe is served better by our survival.
' Any race thinking it's better than another, that's evil.
'I am not evil.
' So what have you done with Clyde? 'Am I not merciful?' What a dream.
'You made all this possible, Sarah Jane.
'I owe you the mercy of a quick death.
' And the others.
Don't they deserve mercy? You've been here millions of years.
You've seen us evolve.
Don't we matter? 'Only my Purpose matters.
' You can 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?' You think I'm alone? You think I'm defenceless? Well, meet my dog! K9, protect me! Affirmative, Mistress.
Maximum defence mode.
Take care, Mistress and you young Master.
Safe to proceed Mistress, I have the unit covered.
Do you wish me to continue firing, Mistress? Just be ready if I need you, K9.
Very good, Mistress.
A robot dog.
Called K9? Affirmative.
I am dreaming, aren't I? 'What have you done to me, Sarah Jane? 'I feel I feel strange.
' A computer virus.
It's closing your databanks.
You're losing memory.
'The speed of light is thirty-six, no, eighty-four 'The Metrabeelen Cosmic Cluster is home 'to 68 thousand lifeforms 67 'I'm forgetting it all.
Sarah Jane! Help me!' Without memories, you have no Purpose.
Without Purpose, you can't destroy the Earth.
Put the moon into its original orbit and set Luke free.
'I've forgotten my Purpose!' To save the Earth.
That is your new Purpose.
To save the Earth.
'Save the Earth.
Yes.
'I have a Purpose.
Thank you, Sarah Jane.
' The unit is non-functional.
He did it! It worked, the moon's going back! Is everything satisfactory, Mistress? Affirmative, K9.
Must return to the distortion, Mistress.
Without my attention, black hole will turn critical in 0.
4 ti2me spatial increments.
Go now.
Good dog.
I'll see you again soon.
Mum? Oh, Luke.
'I've seen amazing things out there in space.
'But strange things can happen wherever you are.
' There they go.
Back to Raxacoricofallapatorius.
And good riddance.
Will they be back? Oh, I expect so.
Sooner or later.
What about Mr Smith? Can we trust him again? The Armageddon Code wiped his circuits.
He'll re-boot with a new purpose to safeguard the world.
Mum! We were just saying what a beautiful night, please come and join us.
'I have learnt that life on earth can be an adventure too, 'you never know you might find.
'In all the universe, I never expected to find a family.
'
# It's been five months since we saw Ashley.
'I have a comprehensive genetic match.
' What? 'Luke and Ashley Stafford are the same person.
' Why can't I remember them? Ashley, thank God.
Children have no place in my life.
You don't mean that.
Go home.

Leave her alone! You killed my father, Sarah Jane Smith.
At the school.
Use your sonic device open the door, open the door! Aaaaagh! You were the child? I didn't want you to die.
But you were going to kill our planet.
Get away from my daughter, you overgrown newt! No.
You drop your weapon.
Or she dies.
Now let her go, frog face.
Dad!.
What now? Now we contact the Xylok.
Get this deal back on the rails.
Once we've found the youngling again.
The Xylok? You know him as Mr Smith.
Why would Mr Smith make a deal with you? He contacted us.
He said he had seen what you did to my family.
He wanted to help us get revenge.
If that was what he wanted, why did he send me here to find the energizer? He sent you here? It's all been part of his plan.
He brought you to Earth to build the telekinetic energizer.
He told me to come here looking for it.
I don't understand.
Neither do I.
Not yet.
But the last part of his plan has just fallen into place.
Mr Smith knew Luke would escape and he knew that, when he did, he would run straight back to my house.
Right back to him.
Sarah Jane! Sarah Jane! 'Luke! Up here, Luke.
' What does Mr Smith want with Luke? Luke.
And the telekinetic energizer headset.
Mr Smith had me steal one of them, the prototype's in my attic.
I don't care.
I'll deal with the Xylok later.
We don't need him for revenge! If you kill us, you won't stop Mr Smith, or get off this planet.
Save your breath.
You'll need it for screaming.
Get off! Let me go! She's my kill! A claw for a claw! When you're older, you'll learn not to make snap decisions.
Now what do you mean? Something Mr Smith said about the energizer.
With the right mind, it could destroy worlds.
He meant Luke's mind.
I think he's planning to destroy the Earth.
'Come in, Luke.
' Where's Sarah Jane? 'She left something for you.
'Put it on, Luke.
' No.
'There really isn't time to argue.
' Clyde? 'Put it on or I will kill him.
' But you're 'Running out of time and patience.
'Put the headset on.
Now! 'That's more like it.
'At last, we can begin.
' ZAPPING NOISE Aaaaaagh! URGENT BLEEPING What's that? MITRE it's gone on-line.
Mr Smith.
He's using the headset on Luke.
Massive telekinetic levels.
They're off the scale.
EXPLOSION What the? The moon! It's moving! It's not possible.
Luke isn't possible.
Mr Smith isn't possible.
But they're bringing the moon crashing down on Earth.
But it's a quarter of a million miles away.
We'll be dead long before it hits us.
The gravitational effect will tear the planet apart.
It's happening.
At least I'll be able to tell my family you're dead, Sarah Jane Smith.
I'm teleporting back to the ship.
You're not! You're as much to blame as Mr Smith! You're staying.
Your ship would be torn apart by gravitational disturbance.
On the other hand, if you help me, we might all just have one chance to survive.
I need you to destroy Mr Smith.
'Give me more kinetic.
Let the universe witness the power.
'Ha ha ha ha ha ha!' 'The moon is heading to earth, causing 'spontaneous forest fires, indeed we have had reports of avalanche, 'freak storms and indeed tidal waves.
'As this continues, it becomes more.
.
' PHONE RINGS Chrissie? Alan, where are you? It's the end of the world! Chrissie, calm down.
Calm down!? Alan, I need to be with you, you and Maria Alan! Chrissie? Chrissie.
The phone line's gone.
We're almost out of time, Alan.
I get paid by companies to block cyber-threats.
I understand viruses, how they work.
But Mr Smith he's more than a computer.
Dad, you're our only chance.
Well, then this is my best shot.
The FBI have stopped a cyber-terrorist from using this to destroy the entire international banking network.
How did you get hold of it? You're not the only one with unorthodox contacts.
Time to show me how this works.
The United Nations is in emergency session to discuss this apocalyptic crisis.
Luke! 'Sarah Jane.
You came to say goodbye.
' Why are you doing this? 'The collision will release the Xylok from beneath the planet's crust 'where it has been buried for 60 million years.
' You're going to kill billions.
'The Xylok are a crystalline life form.
'We crashed here as a meteorite.
'But buried beneath the Earth, 'our crystals have become strong again, but remain trapped.
' The original crystal You're 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 much more than the human race.
'The universe is served better by our survival.
' Any race thinking it's better than another, that's evil.
'I am not evil.
' So what have you done with Clyde? 'Am I not merciful?' What a dream.
'You made all this possible, Sarah Jane.
'I owe you the mercy of a quick death.
' And the others.
Don't they deserve mercy? You've been here millions of years.
You've seen us evolve.
Don't we matter? 'Only my Purpose matters.
' You can 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?' You think I'm alone? You think I'm defenceless? Well, meet my dog! K9, protect me! Affirmative, Mistress.
Maximum defence mode.
Take care, Mistress and you young Master.
Safe to proceed Mistress, I have the unit covered.
Do you wish me to continue firing, Mistress? Just be ready if I need you, K9.
Very good, Mistress.
A robot dog.
Called K9? Affirmative.
I am dreaming, aren't I? 'What have you done to me, Sarah Jane? 'I feel I feel strange.
' A computer virus.
It's closing your databanks.
You're losing memory.
'The speed of light is thirty-six, no, eighty-four 'The Metrabeelen Cosmic Cluster is home 'to 68 thousand lifeforms 67 'I'm forgetting it all.
Sarah Jane! Help me!' Without memories, you have no Purpose.
Without Purpose, you can't destroy the Earth.
Put the moon into its original orbit and set Luke free.
'I've forgotten my Purpose!' To save the Earth.
That is your new Purpose.
To save the Earth.
'Save the Earth.
Yes.
'I have a Purpose.
Thank you, Sarah Jane.
' The unit is non-functional.
He did it! It worked, the moon's going back! Is everything satisfactory, Mistress? Affirmative, K9.
Must return to the distortion, Mistress.
Without my attention, black hole will turn critical in 0.
4 ti2me spatial increments.
Go now.
Good dog.
I'll see you again soon.
Mum? Oh, Luke.
'I've seen amazing things out there in space.
'But strange things can happen wherever you are.
' There they go.
Back to Raxacoricofallapatorius.
And good riddance.
Will they be back? Oh, I expect so.
Sooner or later.
What about Mr Smith? Can we trust him again? The Armageddon Code wiped his circuits.
He'll re-boot with a new purpose to safeguard the world.
Mum! We were just saying what a beautiful night, please come and join us.
'I have learnt that life on earth can be an adventure too, 'you never know you might find.
'In all the universe, I never expected to find a family.
