Same Worlds Meet World's End

None of it makes any sense!

Why would our parents do that - separate us from our twins?

Shh.

More to the point - what are they doing with them down there?

-They're like...lab rats.

-You think they're experimenting on them?

Maybe that's why Mom left with us when we were babies, Noah -

-she didn't want any part of it.

-So why has she come back now?

So, if it's Gaia's twin that's been acting weirdly with us,

where's our Gaia?

-She must be down in the secret zone.

-Where's that, again?

Underneath the castle. You can get to it through the cave.

Yeah, we'll tell you everything we know,

as soon as we get back from there - with Gaia. Let's go.

Hang on, not so fast. Is that the best plan?

Why don't we talk to her twin first,

-find out what it is that she knows...

-No way!

She might not be parallel-universe Gaia any more,

-but she still cannot be trusted.

-Slim's right.

We need to rescue our Gaia, like, fast -

before they start experimenting on her, too.

Are you ready?

Will you look after that for me -

seeing as you're practically my boyfriend now?

Sure...

-We need Lexy.

-Lexy?

-She's the only one can unlock the doors down there.

With her eyeball.

Did he say "eyeball"?

Where is she?

Duncan, what's going on? Is that my Gaia in there, or not?

Let's find out.

Gaia?

Gaia?

She's gone.

KNOCKS AT DOOR

KNOCKS AT DOOR

-You are needed.

-Now.

What for? What's going on? Where are we going?

We'll explain on the way.

-I don't want to go down this way, it freaks me out.

-Tough.

-Why can't I try my eye thing on the main door?

-Too risky.

Anyway, how can Gaia be in danger?

I saw her half an hour ago and she looked perfectly fine to me.

-Lexy, come on.

-Not until you tell me what's going on.

You're keeping something from me - I know you are.

OK.

This may sound a little weird,

but you know how Noah and Luke are twins?

Wow, I never knew that(!)

Well, what if I told you we'd all got twins

and they're being kept prisoner down in the secret zone?

Twins?

And twin Gaia has escaped

and now our Gaia's the one being kept prisoner.

There are two of me?

What are we waiting for? Let's go find them.

No, Lexy - that's not our mission, OK?

Lexy!

CAT SIGHS

KEYPAD BEEPS HYDRAULIC HISS

KEYPAD BEEPS HYDRAULIC HISS

-(Shh, Lexy - keep it down.)

-Look at my nails.

I've broken one and chipped another. They're almost as bad as yours, Cat.

Idiots! What you doing here?

What have you done with Gaia?

The lift...

Follow me now, if you want her back.

Gaia, over here!

Noah!

Cat, is that really you?

Let me out.

-Hurry up and unlock the door.

-KEYPAD BEEPS

I don't understand. This is my room, I should be able to open it.

KEYPAD BEEPS

They must have changed the access code.

-Now what?

-Let me try.

-KEYPAD BEEPS Oh.

-What's that?

Replicates General Winters' iris.

Lars made them for us.

We don't have access to the main door,

so we use these to get in and out of the place.

Let's hope it works here, too.

KEYPAD BEEPS

-Someone's coming.

-Go, now!

With this scanner, we can tell definitively.

-What does it do, exactly?

-You'll see.

KEYPAD BEEPS

Gaia?

Who are you?

This is your father, Gaia.

You asked me to fetch him for you, remember?

What's a father?

What's that?

Relax, it won't hurt.

DEVICE BEEPS

She's the right one.

Who made the decision to chip them?

Lena.

They're not animals.

Shh!

One of us should have gone down there.

We're more Gaia's friends than Noah and Cat.

They know that we're around. It makes sense for them to go.

-You OK, AJ?

-Thinking.

You'll fry your brain, trying to make sense of this, trust me!

-You know that spyware Dad put on my phone?

-He did what?

What if that's the start of them experimenting on us, too?

Monitoring us, seeing how we react to things -

what if all our phones are bugged?

No...

But if our parents were keeping tabs on us,

we would have been busted by now.

Yeah, let's not get paranoid here, OK?

And who'd have guessed, Noah and Cat being so tight with Lexy?

-Yeah, I know.

-And how weird is it,

her being able to open the doors down there with her eye?

Does she actually have take her eyeball out to do that?

SLIM CHUCKLES

-What?

-I can't stand this any more.

Let's go to the cave and wait for them there.

20 minutes ago, you were insisting you weren't who we think you are.

What did you mean by that?

Er... I don't know. I got confused.

I'm not angry with you, I'm just interested to hear

what it is you think you know about the castle upstairs.

Has someone been telling you things?

Someone must have said something.

I don't remember.

Very well.

I'll have to talk to your mentors.

I'll have to keep you confined to quarters

for a little while longer yet, Gaia -

just until we find out exactly what caused this episode of yours.

KEYPAD BEEPS

I don't understand - why couldn't I talk to my dad?

-Because he's in on it, Gaia.

-In on what?

-We were hoping you'd be able to tell us.

-Hey, you're back.

-Gaia?

-Yeah, it really is me.

It's... It's good to see you.

-And you.

-Hey, good work, you two.

LEXY COUGHS

-I mean, "three".

-Thank you.

So come on, guys - what happened?

Yeah, how one earth did you end up down there?

It was after we had the space clearing ritual, remember, Slim?

How could I forget?

I was headed back to my room and that's when I saw her,

stood in the corridor, staring at me.

What are you?

A girl, like you.

See?

-What do you want?

-Come with me and I'll explain everything -

I promise.

'So I went with her.

'Weren't you scared?'

A bit, but somehow I trusted her.

More fool me.

KEYPAD BEEPS

They all have the same names as us -

Caitlin, Lars, Adam, Gaia.

-How weird is that?

-Not very.

My dad's so vain, he obviously named us both after himself.

And then they started asking me all these questions about

why I'd been brought the castle

and what I knew about the adults' work there,

-but I couldn't answer any of them.

-Didn't you ask them any questions?

Well, yeah, I tried, but they didn't really answer them.

And then the other Gaia suggested we exchange places, just for the night.

And you agreed?

I was curious. I wanted to know more about them,

find out why they were there,

and I thought it might actually be fun.

You need to get out more, Gaia.

But then, the next morning, the other Gaia didn't come back

and I began to get a bit worried

and then, things started getting really weird.

We thank you, Origin, ancient and wise,

for teaching us the ways of the universe.

I'm quite into the whole mystic thing myself, actually.

We thank you, Origin, for the wondrous object -

the oracle of our destiny.

-ALL:

-We thank you, we thank you, we thank you, we thank you...

Shall we eat now?

Although I'm not sure what this is supposed to be...

-ALL:

-We thank you, we thank you, we thank you...

-You know what? Enough's enough.

-We thank you, we thank you...

-I think I'd like to go home now.

-We thank you, we thank you...

-Did you not hear what I said?

-We thank you, we thank you...

I want to go home.

-We thank you, we thank you...

-Please, please will you stop that?

GAIA SCREAMS

You'll bring the mentors. It's OK...

Get off! Help!

-Someone, anyone - help!

-GAIA SCREAMS

'I tried to explain that there'd been a terrible mistake,

'but he wasn't listening...'

and then I think he must have given me something,

because the next thing I remember is waking up in the bedroom

-and the door being locked.

-No...

I kept knocking and shouting

and the others started getting really angry,

and they told me to quieten down, but I wouldn't.

And then, eventually, Dr Morelle came to see me.

Still thinking you were Gaia from the secret zone?

But he wasn't sure any more, so then he went to talk to my dad -

-and the rest, you know.

-Do you know what the Origin and the object are?

I don't understand any of it -

the weird symbols everywhere, the food, chanting...

It's just one big nightmare.

I want to go home now, please...

Of course you do. I'm sorry, Gaia.

Come on.

Hang on, she can't go anywhere looking like that.

Oh, yeah - bit of a giveaway, I suppose.

Bit of a fashion disaster, more like.

Adam, a moment of your time, please.

Marcus is back, I'm calling a meeting here, 2pm sharp.

Oh, and Adam...

Lift the ban on the teenagers going into the village.

-What? But...

-We're expecting several deliveries.

Better to have them snooping around there than here, don't you think?

That almost looks as bad as the jumpsuit.

She'll do. Let's go.

So, what about my twin, Gaia? You never mentioned her.

What was she like?

I didn't see a twin of you, Lexy.

The other Gaia nearly ruined our plan.

I should've come back yesterday, like I wanted to.

You were right, we were wrong. Sorry.

Did you learn anything new?

No...

but they are not working with or for the mentors -

that much I do know.

Gaia, you really can't mention any of this to your dad, OK?

Not just yet, anyway - not until we figure out what to do.

How about you? Hope you're not thinking of telling tales to Mummy.

About what?

The hideous toad who followed me out of the cave,

giving me grief I could actually do without?

She's just trying to find out what's going on, like the rest of us, Slim.

OK.

Look, I take it back. Chill.

Thank you, guys...for saving me.
