Part One

SARAH JANE [OC]: Is there anything more beautiful than a star filled sky? As a child, I would dream of what might be up there, but never imagined that one day I would find out. The fiery rings of Coulabria, interstellar lightning across the Voorheiden Horizon. I've seen the death of worlds and the birth of stars. So many wonderful sights, and things to terrify, even here on Earth. Because, although it's easy to forget, we're a part of the universe too, and we really aren't alone. Sometimes, the most amazing people and creatures can find their way to Earth, and so can the most terrifying.

(A tramp is scavenging in a wrecker's yard when a fireball comes hurtling through the sky, to crash nearby. He watches as an armoured biped clambers out from the remains of the old cars it has landed amongst. It scans him, then presses buttons on its forearm.)

SARAH JANE [OC]: Life here can be an adventure, too.

(The tramp runs.)

[Attic]

SARAH JANE [OC]: But after all my adventures, the last thing I expected was a family. And that's been the most amazing adventure of all.
LUKE [on PC]: I've got to go soon. Saturday is band night at the Student Union.
CLYDE: What? You're going to watch a band? We are talking music here? Electric guitars, drums, not some physics experiment with elastic, right?
RANI: Clyde, don't be soft. Soon Luke will have seen more cool new bands than you've ever heard of.
LUKE [on PC]: Yeah, you'll be so after my tunes next time I'm home.
SARAH JANE: Oh Luke, I can't wait.
LUKE [on PC]: Look, I've got to go now, so I'll catch you later.
SARAH JANE: Love you.

(But he's already out of range of the webcam.)

CLYDE: Right, homework.
RANI: Yeah.

[Front door]

RANI: Luke will be back soon, clothes all over the place. Empty mugs, dirty places, lots of loud music.
SARAH JANE: You're tight. I should make the most of the peace and quiet. Night, night.
RANI: Night, Sarah Jane.
CLYDE: See you tomorrow.

[Sarah Jane's home]

(At 5.34 on Sunday, Sarah Jane is woken by an insistent ringing of her doorbell. She opens the front door.)

SARAH JANE: Hello?

(To discover a carry cot on her doorstep. Naturally, it contains a baby.)

SARAH JANE: What the?

(She runs to the road to see who left it, but there are no other people around. She carries the infant indoors.)

SARAH JANE: Oh, why would anyone leave you on a stranger's doorstep?

(The baby cries and all the light bulbs explode.)

SARAH JANE: Oh!

[Chandra home]

(Rani is woken by her text alert tone. 07:12 Help! Come quickly. SJ. Meanwhile, downstairs -)
GITA: All the bulbs in the house? Even the fridge? I'm telling you, Haresh, that's not normal.
HARESH: I'll get an electrician to check the wiring on Monday.
GITA: I hope we're not on a ley line. I saw this programme on the telly. They run all over the country connecting sites of ancient power, like Stonehenge and the White Horse.
HARESH: What, the pub on Bishton Street?
GITA: Very funny, aren't you. You should give up teaching and become an undertaker.

(Rani rushes in, looking for her jacket.)

GITA: Hey, where are you off to in such a hurry?
RANI: Sarah Jane's. Luke's texted me. He can't get an answer. Wants me to check up on her, you know. It's probably nothing. Bye.
HARESH: Phone's probably on the blink. It'll be the ley lines.

(Rani leaves.)

GITA: Here, how many comedy headmasters does it take to change a light bulb?

[Attic]

RANI: Sarah Jane, what's
SARAH JANE: Shush.
RANI: That baby doing in your arms?
SARAH JANE: Shush. Don't make her cry. She cried earlier, and every light in the house blew.
RANI: In the street, more like.
CLYDE: I got what you said in your message, but what do you want nappies for? (then he sees.) I sort of feel that should explain everything, but actually I'm even more confused.
SARAH JANE: I found her on the doorstep. I was going to call the police, but I don't think they'll have much luck finding her parents. Not on this planet.

(Baby cries, bulbs go bang.)

SARAH JANE: Shush, it's all right. it's all right. Luke was born a thirteen year old boy. A teenager I can handle. But a baby? An alien baby? I need help.
RANI: Don't look at me.
CLYDE: Or me, obviously.
SARAH JANE: Yeah, well, your mums must know.
RANI: If I start asking Mum questions about how to look after a baby, well, she's going to totally freak. Besides, she's an alien. What do any of us know?
CLYDE: What about Mister Smith?
SARAH JANE: Ah. Mister Smith won't come out. Well, would you if you might get your circuits fried?
RANI: You see, with most babies, all you have to worry about is poo and puke.
SARAH JANE: Yeah, well, this one doesn't blow bubbles, she blows things up.

(Whaa! Bang!)

CLYDE: I only know one way to shut up a baby.

[Lounge]

(So Clyde gets to feed baby her bottle of formula milk.)

CLYDE: See? Happy tummy, happy baby, whatever planet you're from. I've looked after my little cousin a few times, not that she's an alien.
RANI: You're a natural, Clyde.
CLYDE: Well, little kids are cute, aren't you, Sparky?
SARAH JANE: Do you think so? I always think babies look a bit rubbery.
RANI: Her mum and dad will be going out of their minds with worry. They must be scouring the galaxy.
SARAH JANE: Maybe. Maybe not. Whoever left her on my doorstep, that was no accident. I think someone needs me to protect this baby.
CLYDE: Protect her from who?
SARAH JANE: That's what we have to find out, before they come looking for her.

[Summerwell nuclear power station]

(A technician is walking through the turbine hall when static electricity starts playing over various metal surfaces. Then a big round energy ball appears, like the time travel balls in Terminator.)

CALEB: What is that? Oh, no.

(He is knocked down by the force as a fully clothed woman walks out of the ball. She walks over and puts her stiletto heel boot on his chest.)

MYERS: You're flesh. Good.
CALEB: Who, who are you?
MYERS: My name is Miss Myers, and you're going to help me find my child.

(She energy zaps his face.)

[Outside Sarah Jane's home]

SARAH JANE: I've scanned her. Now, give the readings to Mister Smith and hopefully he can give us a clue who she is and where she came from.
CLYDE: Received and understood. If Sparky blows her top again, we don't want her any where near Mister Smith.
SARAH JANE: Right. Time to get clear of Bannerman Road. Park should be safe enough.
RANI: Yep.

(Gita walks up the drive.)

RANI: Oh, no.

(Rani hands the carry cot to Sarah Jane.)

GITA: There you are, Rani. Oh, is there something you've not been telling us, Sarah?
RANI: Mum, there is a simple explanation.
GITA: Oh, you've started fostering, haven't you, darling? How wonderful. I always thought you made such a perfect mum to Luke.
SARAH JANE: Oh, thank you, Gita.
GITA: No wonder Luke couldn't get you on the phone. Bet she's a proper little handful. Aren't you? Aren't you, my
SARAH JANE: Yes, well, it was all a bit sudden, really. Yes, I practically opened the door and there she was, like she'd fallen out of the sky.
GITA: Oh, like that thing last night. What's her name?
CLYDE: Her name?
SARAH JANE: What thing last night?
GITA: I heard it on the local radio. A meteor landed in that wrecker's yard on Peel Road.
RANI: A meteor?
GITA: She must have a name, Sarah.
SARAH JANE: Sky.
GITA: Sky?
CLYDE: Yeah. Like she'd fallen out of it.
GITA: Oh, that's beautiful. Just like you.

(Baby Sky squeals, and all the car alarms in the street go off.)

GITA: Oh, flipping heck. First all the light bulbs, and now the car alarms. I'll catch up with you later.

(Gita leaves.)

CLYDE: An alien baby turns up on your doorstep and a meteor crashes on the same night? That's like a galactic coincidence.
RANI: We should check it out.
SARAH JANE: Absolutely. Clyde, give me my watch back. Mister Smith can analyse the scan later. We need to check out what's landed in the wreckers yard.

(She hands the carry cot to Clyde.)

CLYDE: What? What are you doing?
SARAH JANE: There's no baby seat. And the last thing I need is her blowing the car's electrics. And make sure Mister Smith stays out of harm's way.
RANI: You'll be fine. You're a natural.
SARAH JANE: Look after her, Clyde. I'm sure someone left her here because she's in danger. I'm relying on you.
CLYDE: Yeah, yeah. Don't worry.

[Control room]

MYERS: Take a power nap, boys.

(She zaps the workers, and they go to sleep on their feet.)

MYERS: I'm looking for a power surge in the area last night.
CALEB: Here. Exploding light bulbs.
MYERS: Bannerman Road. Don't worry, baby. Mummy's coming to get you.

(So is the thing from the wrecker's yard.)

[Wrecker's yard]

RANI: So you think Sky's in danger?
SARAH JANE: Why else would anyone leave her on my doorstep? What's got me confused is, who put her there?
RANI: The Doctor?
SARAH JANE: Oh, he'd never just leave her and take off without a word.
POLICEMAN: I'm sorry, you can't come through here. It's dangerous.
CELESTE: It's all right. Miss Smith is quite used to danger.
SARAH JANE: Professor Rivers!
CELESTE: Sarah Jane. Good to see you again. Come through, come through.
SARAH JANE: Thank you.

(In amongst the rubble.)

RANI: So where's the meteor?
CELESTE: Good question. We know a body impacted. Our seismographs at the Pharos Institute recorded it.
RANI: You don't really need a seismograph to see that, Professor.
SARAH JANE: Well, this was no meteor, and these energy traces don't look like any life form I've ever seen before.
CELESTE: You mean an alien?
RANI: Sarah Jane?

(Rani has found a big boot print.)

RANI: Whatever landed here last night, it had big boots.
CELESTE: Not only big, but heavy. Very heavy.
SARAH JANE: Whatever was here, there's something else now.
CELESTE: Something alien?
SARAH JANE: No, human.

(The tramp.)

SARAH JANE: Hello. No, no, no. It's all right. I only want to talk. After him. He might have seen something.
CELESTE: Oh, wait for me. I'm in Wellingtons!

[Hugo's home]

(The tramp runs through the piles of old cars into a home he has built for himself out of spare parts. It has a van door for a door.)

HUGO: I wasn't doing anything wrong.
RANI: What have you been living off, battery bunnies?
HUGO: They're for my radio. Not that it works since that great ruddy iron bloke dropped down last night.
SARAH JANE: Yeah, well, my name is Sarah Jane Smith. I'm a journalist. I just want you to tell me what you saw.
HUGO: The press? I'm not talking to you. I've seen what you put in the papers about people that have seen what I've seen. I do read them, you know.
RANI: It's all right. You can trust Sarah Jane.
HUGO: And I won't be able to listen to The Archers now.
SARAH JANE: Oh, well, what if I fix your radio for you. Will you tell me what you saw?
HUGO: With a lipstick? I'm homeless, I'm not brainless.

(Sarah Jane sonicks his transistor radio and it comes back to life.)

HUGO: It works. You fixed it. How did you do that? What sort of batteries do you use in that thing?

[Lounge]

CLYDE: And then the big bad Bane went bang, and everyone got covered in gunk.

(Gurgle.)

CLYDE: Don't, don't.

(His phone rings.)

CLYDE: This is Clyde. Speak to me. Thanks, Sparky. Flat as Jedward. No, no, don't cry, don't cry. Oh, come on, think, Langer. You're a born entertainer.

(So he tries mime, walking down pretend steps behind the sofa, etc.)

CLYDE: Say hello to Sid the Sleeve. Hello, Sky. Hello, Sid. What do you call a man who wears paper trousers? I don't know, Sid. Russell! Yeah, do you get it? No, too advanced, obviously. No, no, no. Don't cry, don't cry.

[Hugo's home]

SARAH JANE: Please, I just want you to tell me exactly what you saw.
RANI: You saw an iron man. Like a robot?
HUGO: Did I say he was a robot? No. I know what a robot looks like. I've seen Star Wars. This was a bloke. His skin was all metal.
SARAH JANE: Well, what happened?
HUGO: He fell out of the sky, and then stood up without a scratch on him and turned himself invisible.
RANI: Invisible?
HUGO: That's right. And I'm telling you this. He was armed to his flaming big steel choppers. If there's any more of them on the way, we don't stand a chance.

[Wrecker's yard]

RANI: A metal man? Is that even possible?
SARAH JANE: A biometalloid life form. Why not? It's a big universe. But now it's here and it's got to be looking for Sky.

(She tries her mobile phone.)

SARAH JANE: Oh, Clyde's not answering. Whatever it is, we've got to find it before it finds Sky.
RANI: Er, it's invisible.
SARAH JANE: Well, nothing's ever completely invisible.
CELESTE: Oh, there you are. What have I missed?
SARAH JANE: Celeste, do you have equipment on your van that can track an ultra high frequency electromagnetic signal?

[Garden]

CLYDE: Okay. No computers out here. No alien tech, no phones. You're safe. Oh, you like leaves. Leaves are good. Leaves are green. But not salad. Salad's green but it's also kind of yuck.

[Outside the Chandra home]

CALEB: Hello, Mister Chandra. We're from West London Power.
HARESH: This wouldn't be about all the bulbs blowing, would it?
CALEB: There was a freak power surge in Bannerman Road. We're visiting every house, looking for the cause.
MYERS: It needs to be isolated.

[Pharos Institute van]

SARAH JANE: Whatever crashed here emitted UHF electromagnetic radiation. That's what scrambled the radio. And whatever made those footprints might be able to make itself invisible, but it can't hide that energy trace.
CELESTE: There's something here. A regular UHF-ME pulse. And it's moving.
SARAH JANE: Right towards Bannerman Road. Rani, try Clyde again. Warn him. He has to get Sky away from there.
CELESTE: Who's Sky?
SARAH JANE: A defenceless child, and there's something very dangerous coming after her.
RANI: He's still not answering.
SARAH JANE: Come on. Thank you, Celeste.
CELESTE: Oh, my pleasure. Oh, and be careful.
SARAH JANE: Oh, I'm never careful. Always prepared.

(Rani and Sarah Jane leave. Celeste takes out her own lipstick.)

CELESTE: Zap! Zap, zap!

[Chandra home]

HARESH: Every light in the house went, and I don't suppose West London Power are going to reimburse me for those, are they?
MYERS: I'm afraid not. Mrs Chandra, do you have young children?
GITA: No. Just our daughter, Rani. She's seventeen, and very clever. She's going to be a journalist.
HARESH: What do children have to do with your company blowing our lights?
GITA: And you're going to blow a blood vessel, Haresh, if you don't calm down. Would you like a cuppa, my darlings? Now, our neighbour over the road, she's just fostered a baby. Earl Grey?

[Garden]

(The invisible visitor arrives in the road.)

CLYDE: And that's a tree, and oh, and this is grass. Cows eat grass. And they go moo and they make milk. You like milk, don't you. They also make steak. I like steak. Especially with chips. But they have to come from the chippie, definitely not from the oven. Oven chips are the work of bad cooking goblins.

(The gates appear to open on their own.)

CLYDE: Did you hear something? It was more like feel something.

(Footprints appear in a flowerbed.)

CLYDE: Oh, what made those?

(Clyde reaches out and knocks on something metal.)

CLYDE: Oh, this is not good.

(The metal man makes himself visible.)

CLYDE: Not good at all.

(And produces a gun.)

CLYDE: Not getting any better. Uh oh.

(He looks over its shoulder.)

CLYDE: Hi!

(Metal man turns. Clyde grabs Sky's carry cot and runs, dodging energy bolts.)

[Bannerman Road]

MYERS: Get in if you want the child to live!
CLYDE: Who are you?
MYERS: I'm her mother. Drive.

(Clyde gets into the back of the West London Power van. They zoom away with energy bolts bouncing off the back, then the metal man goes invisible again.)

[Chandra home]

GITA: Did you hear that?
HARESH: Don't worry. After the lights exploding and all the car alarms going off, it'll probably be the gas mains blowing up. Just a regular day on Bannerman Road.

[WLP van]

CLYDE: I don't know about you, Sky, but my mum always told me never to take lifts off strangers.

[Sarah Jane's home]

SARAH JANE: Clyde? Clyde?
RANI: He's not here.
SARAH JANE: Clyde!

[Attic]

SARAH JANE: Mister Smith, I need you now.
MR SMITH: Sarah Jane, what can I do for you?
SARAH JANE: I need you to find Clyde. Connect with every CCTV camera in London, every speed camera, whatever it takes, just find him.
MR SMITH: There are five hundred and twenty one thousand, three hundred and twenty one CCTV cameras in operation across London, Sarah Jane. It may take some time.
SARAH JANE: Just do it.
RANI: Maybe he's just taken Sky for a walk?
MR SMITH: He is at the Summerwell Nuclear Power Station.
RANI: Well, that didn't take long.
MR SMITH: I was lucky. It was only the ten thousand and fifty second camera I checked.
SARAH JANE: Who is that woman?
MYERS [on screen]: My name is Miss Myers.

[Summerwell nuclear power station]

CLYDE: That doesn't sound like much of an alien name.
MYERS: We don't spell it the same way. Now give me the child.
CLYDE: No, no, no. Answers first. What was that thing back there and why is it after the baby? And what are we doing here?

[Attic]

SARAH JANE: Come on.

[Summerwell nuclear power station]

MYERS: My child has a destiny. A destiny to change worlds, and that some will do anything to destroy.
CLYDE: Oh, what, like Tin Man back there?
MYERS: Hmm? The metalkind. The enemies of my species. Of all flesh.
CLYDE: But I don't get it. She's just a baby.
MYERS: How could you even begin to understand? You might be flesh, but you are Earth flesh. Just a few evolutionary twists from protozoa. Now give me my child!
CLYDE: I don't think so.

(Clyde runs off.)

MYERS: Get him!

(The man chases Clyde through the turbine hall and down some stairs. Clyde hides behind a pair of sleeping workers and the man runs on.)

CLYDE: Typical I'm in the middle of a nuclear power station and I'm carrying Baby Bang Bang.
MYERS [OC]: Find the boy!

[Outside the power station]

SARAH JANE: Looks like a back door to me.
RANI: See, why would that woman take Clyde and Sky to a nuclear power station?
SARAH JANE: I don't know, but you've seen the effect she has on anything electrical. Imagine what could happen there. Come on, we may not have much time.

(They leave the gate open for the invisible metal man to go through.)

[Summerwell nuclear power station]

MYERS: Oh, how perfect. You see, a baby will always find her mother. Give her to me.
CLYDE: No. What are you going to do to her?
MYERS: Take her home, of course. She's the saviour of my kind. She will be the stuff of legend. Now give her to me!
SARAH JANE: Clyde! Clyde, run!

(Then the now visible metal man turns up.)

RANI: Oh, boy.
METALKIND: The flesh whelp must be destroyed.
MYERS: No!
SARAH JANE: Get back. I won't let you hurt this child.
METALKIND: She is no child. She is a weapon.
MYERS: And she is unprimed. She isn't ready for this. You have doomed us all!

(Sky starts crying. Energy plays around her carry cot.)

RANI: What's going on?
SARAH JANE: Sky's energy, it's flooding out of her.
MYERS: Yes, the weapon is priming itself. Your presence has activated it. The doom of the Metalkind is come!

(Sky transforms into a young girl.)

SARAH JANE: Sky?

Part Two

[Summerhill nuclear power station]

RANI: What just happened?
SARAH JANE: I think Sky just grew up.
CLYDE: What, with no birthdays? That's just rubbish.
METALKIND: I am too late.
MYERS: Face your destruction, Metalkind. The child is your doom.

(Energy plays over Sky.)

SKY: What's happening to me?
MYERS: Destroy him!

(Sky throws an energy bolt at Metalkind, and he flies back backwards into a wall.)

MYERS: Again, my child.
SARAH JANE: No.
SKY: What am I?
SARAH JANE: Oh, Sky, don't be frightened.
MYERS: You are the hammer to crush the Metalkind. You are the weapon and salvation of our species. Destroy your enemy.
SARAH JANE: No, Sky. You don't have to destroy anything. You don't have any enemies. Just be calm, and trust me. It's all right.
SKY: Sarah Jane?
SARAH JANE: Everything's going to be all right, I promise.
MYERS: Stop your meddling. Come with me. Return home and fulfil your purpose.
SARAH JANE: I don't think she wants to go with you.
MYERS: I am the child's mother.
CLYDE: Introducing Miss Myers. She spells it the alien way.
SARAH JANE: Well, my name is Sarah Jane Smith, and I don't think you're a fit parent.
MYERS: She is a weapon, grown in a laboratory to destroy the enemies of my species. I grew her.
SKY: What does she mean?
RANI: Oh, don't listen to her, Sky.
SARAH JANE: Well, none of us can help the way we come into this universe, but we have a say in what we become. And whatever you had planned for her, this is an innocent child, not a weapon, and I will protect her from the Metalkind and I will protect her from you.

(Sarah Jane sonicks a piece of equipment to create sparks as a diversion.)

SARAH JANE: Run!
CALEB: Shall I stop them?
MYERS: I have a better idea.

[Outside the power station]

SARAH JANE: I have to get you as far away from that woman as I can.
SKY: Is she really my mother?
SARAH JANE: All I know for sure is somebody brought you to me to protect you, and that's what I've got to do.

[Summerhill nuclear power station]

(Miss Myers kneels over the fallen Metalkind and takes his gun.)

METALKIND: Have you come to finish the job, Fleshkind? Perhaps your weapon isn't as powerful as you thought.
MYERS: The weapon will do its job. And you're going to help me. (to Caleb) Wire him up.

[Outside Sarah Jane's home]

SKY: This is where you live, I remember.
RANI: What, you remember when you were a baby?
CLYDE: It was only about half an hour ago.
SKY: Why do you call a man who wears paper trousers Russell?
SARAH JANE: I beg your pardon, hmm?
CLYDE: It was a joke. It was meant to be funny. You know, it was supposed to make her laugh. Boy, does this feel familiar.
SARAH JANE: You were telling her jokes?
CLYDE: I was trying to stop her crying.
RANI: By making her laugh? You know what she does when she laughs.
SKY: I like Sid the Sleeve.
CLYDE: You had to be there. It's like
SKY: Everything's so green.
RANI: Well, this is England. It rains most of the time.
SARAH JANE: Sky, do you remember being brought here? Can you remember by who?
SKY: You are the first thing I remember.
SARAH JANE: Oh, I see. Well, now that you're grown up, can you control your powers?
SKY: I think so.
SARAH JANE: You've got to promise me that you will, because I need you to meet a friend of ours.

[Attic]

CLYDE: Welcome to the Bat Cave.
SKY: There's a cave on top of the house?
RANI: It's not a cave. It's an attic. Clyde was joking again. He does that. Sort of.
SARAH JANE: Mister Smith, I need you.

(But he doesn't come out of the fireplace.)

RANI: What's going on?
SARAH JANE: It's all right. Sky won't hurt you.

(Mister Smith comes out.)

SKY: Wow!
MR SMITH: Is the child under control?
SARAH JANE: It's all right. I promise.
SKY: What are you?
MR SMITH: I am a Xylok. A crystalline life form with highly sensitive cybernetic interfaces. I would be grateful if you would remain distant.
SKY: But can we still be friends?
MR SMITH: If my circuits remain intact.
SARAH JANE: Sky has undergone a metamorphosis. I need you to make sure she's unharmed. Now don't worry, it won't hurt.
MR SMITH: Scanning.
SKY: It tickles.
MR SMITH: Please, try not to laugh.
SARAH JANE: Mister Smith, stop fussing and analyse the scan.
MR SMITH: Biologically, Sky appears to be a healthy twelve year old child.
SKY: Twelve? Is that a good age?
RANI: Well, until the spots start.
SARAH JANE: Rani, take Sky. Have a look through Luke's things. See if you can find her something to wear.
RANI: Sure. Come on, Sky.

(Rani and Sky leave.)

SARAH JANE: Mister Smith, how did she transform into a teenager?
MR SMITH: Sky's synthetic DNA was programmed for this level of maturity to maximize her effectiveness.
CLYDE: As a weapon?
MR SMITH: As a bomb. Full activation would not only destroy Miss Myers' enemies across the universe, but also kill Sky.

[Luke's room]

SKY: Is Sarah Jane Luke's mother?
RANI: Yeah. She adopted him. Luke was made by aliens that wanted to take over Earth.
SKY: I like Earth. It's beautiful, noisy, smelly.
RANI: Yeah. It's all that. This must be so weird for you. Like, seeing the world for the first time. Everyone else, they just sort of grow up with it.
SKY: It's exciting.

(Rani lays out jeans and a t shirt.)

RANI: Try these. Now, they're not exactly fashion but you'll be all right.
SKY: What's fashion?
RANI: Clothes. Like wearing nice clothes, made for a girl.
SKY: What's a girl?
RANI: And Clyde thought he had it tough with Luke. Okay, let's log on to Ranipedia.

[Attic]

SARAH JANE: Why have they done this? To create a child that's a bomb. What sort of sick species is Miss Myers?
MR SMITH: A binary planetary system exists at the eye of the Tornado Nebula. One has carbon based life forms similar to those on Earth. The other evolved as boron based life.
CLYDE: And for those of us who were watching the netball team out the window during chemistry?
MR SMITH: Boron is a metalloid element.
SARAH JANE: On one planet, people evolved like us. Blood, bones, flesh. On the other, metal. That's amazing.
CLYDE: So this Fleshkind planet, that's where Sky's from?
MR SMITH: Yes. The Metalkind and Fleshkind have been at war for centuries. I believe Sky was created as a doomsday weapon to destroy the Metalkind.
SARAH JANE: Of all the terrible things I've seen, I've never known anything as hideous as using a child as a bomb.
SKY: What's a bomb?
SARAH JANE: Oh, Sky.
SKY: Miss Myers said I was a weapon. That's bad, isn't it? Am I bad?
CLYDE: No. No way. Miss Myers, she's the bad one, not you.
SKY: What am I, then?
SARAH JANE: The thing inside you. Miss Myers created you like that to kill her enemies, Metalkind.
SKY: Kill? What's kill?
SARAH JANE: You take away life. It dies. It no longer exists. And that's wrong. It's always wrong.
SKY: But if that's what I was made to do, that makes me bad.
RANI: No, because it's not your fault.
SARAH JANE: Mister Smith, there must be a way to reverse what Miss Myers has done to her.
SMITH I regret not. At a molecular level, Sky is a weapon programmed to destruct on contact with energies of massed Metalkind. I'm sorry, this cannot be undone.
CLYDE: Okay, if she's a bomb, can't we just defuse her?
SARAH JANE: Oh, Clyde. That's brilliant. Turn off the genetic trigger. Stop her detonating. Mister Smith, is that possible? So genetically she'd be a weapon but disarmed.
MR SMITH: Only Sky's creator can do that.
SKY: Then let's go ask her.
SARAH JANE: Sky, it's not going to be as easy as that. Taking you back to the power station, that's dangerous.
SKY: What's dangerous?
RANI: You could die.
SKY: Mister Smith said I could die, anyway. I don't want to be a bomb. Sarah Jane, will you help me?

[Outside the power station]

RANI: I can't help thinking this is a bad idea.
SARAH JANE: I know. The last thing I want is that woman anywhere near Sky. But Miss Myers is the only one that can deprogram her DNA, so she has to come with us.
CLYDE: Before we get as far as that, a small point. Miss Myers may have put the techies into a trance, but the guard looks lively.
SARAH JANE: I don't want to risking the gates again. Old investigative reporter's superstition. Never break in the same way twice.
SKY: I can do this.

(In his office, a guard watches the CCTV showing Sarah Jane driving towards the station, while he sips his mug of tea. The patrolling guard joins him just as all the car alarms in the staff car park go off. They run outside to investigate, and Clyde sonicks the barrier up behind their backs so that they can drive through.)

SARAH JANE: Now, I need you to stay here with Clyde and Rani.
SKY: What for?
CLYDE: Yeah, ditto.
SARAH JANE: I need to make sure that Sky is safe until I'm ready.
RANI: Oh, great, so we get baby-sitting duty?
SKY: Who are you calling a baby?
SARAH JANE: We're doing this by my rules, Sky. Until I convince Miss Myers that there's another way to end this war, a peaceful way, you're still in danger, and I need you to stay with Clyde and Rani. Now, do you promise me?
SKY: I suppose.
SARAH JANE: Right.

[Summerhill nuclear power station]

(Sarah Jane checks the sleeping techies, then Caleb sneaks up on her.)

SARAH JANE: Oh. Good. Now, take me to your leader.

[Outside the power station]

SKY: She might need our help.
RANI: She told us to stay here.
SKY: Do you always do what Sarah Jane tells you to?
CLYDE: Look this is a nuclear power station, which makes going in with you like doing a Houses of Parliament tour with Guy Fawkes.
SKY: What are you talking about?
RANI: He means it's not safe. Anyway, you promised.
SKY: I don't really understand promises.

(Sky runs towards the main building.)

RANI: Hey, wait!
CLYDE: That kid's going to get us into so much trouble.

[Control room]

MYERS: Miss Smith. Welcome back. Complete your work. I trust you're taking good care of my child?
SARAH JANE: Yes. You won't be getting your hands on her again.
MYERS: Don't judge me. Do you think I like what this war has forced me to do? To become?
SARAH JANE: Then I'm asking you, deactivate what you've done to Sky.
MYERS: Deactivate? She is our saviour. Her touch carries the power and the fury of an exploding sun. Once fully unleashed it will destroy every Metalkind in existence.
SARAH JANE: And Sky will be destroyed along with them.
MYERS: A sacrifice for the preservation of Fleshkind.
SARAH JANE: That's not a sacrifice, that's slaughter. Listen to me, please. There are other ways to end a war. You just have to want peace more than death.
MYERS: You know nothing. For centuries the Metalkind have savaged my people. They have swore to destroy all flesh, and what chance does flesh have against jaws and blades of iron and steel? But perhaps you will learn.

(Miss Myers calls up a CCTV image on a screen. Caleb is wiring the Metalkind into the power station.)

SARAH JANE: What is this?
MYER: The child damaged the Metalkind just enough for me to make use of it. As a homing device.
SARAH JANE: A homing device? For what?
MYERS: It's being wired into the nuclear core. At the flick of a switch it will summon Metalkind and they will swarm here in hordes.
SARAH JANE: You're bringing your war to Earth?
MYERS: Once your Fleshkin experience Metalkind savagery, you will realise that the child will save us all. Caleb, make the final connection.
SARAH JANE: Metalkind, stop this. Earth has done nothing to hurt your people.
METALKIND [on screen]: Fleshkind tore the ore from our planet's womb to make their dumb slaves. They stole our children. We have sworn vengeance on all Fleshkind, on any world.
MYERS: I've scrambled its brain. He thinks he's calling all Metalkind to a glorious battle against Flesh, not to its destruction.
SARAH JANE: You're wasting your time. I will never give you Sky.
MYERS: It doesn't matter. The child is primed to activate on exposure to the massed energy of the Metalkind. When they come, they will be destroyed. She cannot stop it, and neither can you.

(She presses a buttton, and energy pulses through Metalkind.)

[Power station]

METALKIND: Come to me, Metalkindred. Join me and rend flesh.

(Elsewhere.)

CLYDE: What is it?
SKY: The Metalkind. I can feel them. They're coming.

[Control room]

SARAH JANE: If you bring the Metalkind to Earth you're worse than them. You're bringing war to an innocent planet.
MYERS: This is survival. But there's still time before I open the portal. Bring me the child and I will take her home to face our enemy, and your planet will never know the butchery of the Metalkind. What would you put first, Miss Smith? One child or your entire world?
SARAH JANE: Wait and see.
MYERS: Whatever you choose, Sarah Jane Smith, Sky will fulfil her destiny.

[Power station]

SARAH JANE: Sky! I thought I told you to keep her away.
RANI: She says the Metalkind are coming.
SKY: I've got to stop them.
SARAH JANE: No. Wars are ended by people talking, not by killing.
SKY: But Earth won't stand a chance. You've been kind to me, Sarah Jane. You've tried to keep me safe, but this is what I was created for.
SARAH JANE: Sky, listen to me. This is wrong. Killing is always wrong. If you confront the Metalkind, you will die.
SKY: If I don't, you will. Maybe this is why I was brought here. To save Earth.

(Sky runs into a lift and closes the doors with her energy.)

SARAH JANE: No, Sky.
CLYDE: Sky!
RANI: This way.
SARAH JANE: No. I'll go after Sky. You get to the control room and shut down the reactor to stop the Metalkind coming through.
CLYDE: Shut down a nuclear reactor? How exactly are we suppose to do that?
RANI: We find a way. Any way.

(Sky has gone down to the basement where Caleb and the Metalkind are. Meanwhile, Clyde and Rani find a guide to the power station.)

CLYDE: Okay, okay, control room, control room?
RANI: Control room, come on.

(Energy plays over Sky as she slowly approaches the Metalkind.)

SARAH JANE: Sky, stop it. You mustn't.
SKY: Stay back, Sarah Jane.
MYERS: You are too late, Sarah Jane Smith. The portal has opened. The Metalkind come, to their death.
SKY: I have to save you, Sarah Jane. I have to save Earth.

[Control room]

(Alarms are going off.)

RANI: Clyde.
CLYDE: What's all this about? It looks like a big arcade game.
RANI: This is what controls the nuclear fuel rods.
CLYDE: It's just like a James Bond movie. Pull out the rods, close down the reactor, save the world.
RANI: Only it's more like James Bond meets Mario.
CLYDE: Which is ace, because I'm brilliant at Mario.
RANI: If we don't do this right, Clyde, we don't just go back to the last level.

(They use the joysticks to target the rods on the screen.)

CLYDE: But it's not coming out.
RANI: It's not working.

[Power station]

SARAH JANE: Sky, don't let them use you.
SKY: It's what I am, Sarah Jane.
SARAH JANE: You're not a weapon. Not if you don't want to be. You are a child. A beautiful, innocent child. Remember what I told you, it's wrong to kill.

[Control room]

CLYDE: What are we doing wrong? What?
RANI: We've got to remove them in order. Two at a time.
CLYDE: Order? What order?
RANI: It's a spectrum. Richard of York gave battle in vain.
CLYDE: What?
RANI: Just do it. Red, orange, yellow, green, blue, indigo, violet. Well, come on. We haven't got much time.

[Power station]

(The big energy ball is getting noisy. Sound of distant marching boots.)

SKY: It's too late. They're coming. They're here!
MYERS: The end is nigh!

[Control room]

(The last two rods are ready to be removed.)

CLYDE: Almost.

[Power station]

SARAH JANE: No, Sky!

[Control room]

CLYDE: Last one.

(Sky screams and the portal disappears.)

[Chandra home]

(Power cut.)

GITA: What did you do to the telly?
HARESH: That does it. Tomorrow we get this house rewired.

[Control room]

COMPUTER: Emergency lighting activated.

[Power station]

(Clyde and Rani run to join the others. Sky is lying on the floor.)

MYERS: What have you done?
CLYDE: We did it. We shut down the core.
RANI: What happened?
SARAH JANE: All that energy had to go somewhere. Sky was like a lightning rod. She absorbed it all.
CLYDE: Is she going to be all right?
SKY: Wow!
SARAH JANE: Are you all right?
SKY: I feel, I feel different.
MYERS: You are different. I can feel it, too. That energy backlash, it's destroyed your genetic programming.
SKY: You mean, I'm not a weapon?
MYERS: Not even a peashooter. I have lost my daughter.
SKY: You saved me. And I'm not a bomb any more. Thank you.

(The Metalkind breaks free and grabs Miss Myers.)

METALKIND: I saved some energy just for you, Fleshkind.

(He transports them both away. Caleb 'wakes up'.)

SARAH JANE: Uh oh. I'm too tired to think of clever answers for awkward questions. Come on. Let's go home.

[Outside Sarah Jane's home]

CLYDE: Right, so all that light bulb popping and stuff, that's all finished?
SKY: I think so.
SARAH JANE: Mister Smith will be relieved. And thank you. I can always rely on you two to throw the switch when it matters.

(Gita and Haresh arrive with a bouquet of flowers.)

GITA: Sarah!
RANI: Mum.
GITA: I was telling Haresh all about you fostering beautiful baby Sky. Hello.
SKY: That's me. Hello.
HARESH: I thought you said she was a baby?
GITA: She was.
SKY: I grew up.
SARAH JANE: Yes, well, that's what babies do. But not just in one day. Obviously.
RANI: Obviously.
CLYDE: That would be, well, you know, alien.
SARAH JANE: Yes, there was a mix-up. Social services brought me the wrong child. Would you believe it? They brought me a baby called Sky when it should've been a teenager. With the same name. Sky. Sky Smith.
GITA: Sky Smith? Amazing.
SARAH JANE: Yes, she is. Really amazing. Now, if you'll excuse us.
GITA: Sky Smith.

(Gita and Haresh leave. The car headlights flash.)

RANI: Did you just see that?
CLYDE: Yeah, I reckon Sparky hasn't totally lost her spark.

[Attic]

SARAH JANE: I just want Mr Smith to make sure there are no ill-effects from that energy blast.

(Squark!)

SARAH JANE: What?
SHOPKEEPER: Really, Miss Smith, how can you possibly see through this?

(It is the macaw and his sidekick from Lost in Time, who is looking through the telescope.)

SARAH JANE: How did you get in here?
SHOPKEEPER: I'm afraid the Captain considers that privileged information.
SARAH JANE: Oh, yes, I forgot. You're the one in charge, aren't you?
SKY: The bird?
SHOPKEEPER: Things are seldom quite what they seem, young lady. And my, haven't you grown?
SARAH JANE: What, it was you? You brought Sky here?
SHOPKEEPER: And might I say, what a perfect name for such a perfect child, young Sky.
SARAH JANE: I'd still like to know who you are. Both of you.
SHOPKEEPER: Consider us servants of the universe.
SARAH JANE: Which means what, exactly?
SHOPKEEPER: Sometimes, things can't be left to chance. Sometimes, a breeze must blow from east to west, not north to south. Sometimes, a sky should be blue, not laden with cloud. And sometimes, a child must find her way home. Which is my task, Miss Smith. To put things in the right place. And of all the homes in all the universe, I could find none safer for this child than yours.
SARAH JANE: But who are you?
SHOPKEEPER: All in good time.
SKY: So, have you come back for me?
SHOPKEEPER: Well, that depends on you.
SKY: Can I stay here with you? That's what I want.
SARAH JANE: Oh, Sky, it's only been a day and I feel like I've known you since you were a baby. Yes, this is your home for as long as you want it to be.
SHOPKEEPER: Well, that's that then. Jolly good. Until the next time.
SARAH JANE: Oh, no, wait.

(The Shopkeeper and Captain vanish.)

SKY: Who was he, then?
SARAH JANE: I haven't the faintest idea. but I dare say we'll find out all in good time. Oh, you must be starving. How does pizza sound?
SKY: What's pizza?
SARAH JANE: Come on.
SARAH JANE [OC]: But the most wonderful thing about the universe is that there's always something more amazing to come.
