Proof? World's End

This is seriously messed up.

-What is that?

-The Object.

-That's The Object?

Luke found a stone circle like that down in the cave.

Why has Casey got a picture of it up here?

It was around here somewhere.

There! There is it.

I didn't want to pick it up in case it was ancient, you know?

You beauty!

Wait, there could be more buried around here.

-It'll be getting dark soon.

-No, no, I can run and get us a flashlight.

Some other time, Luke, eh? I'm under the cosh at the moment, mate.

OK, yeah, sure.

More importantly, why has he got photos of us up there?

Am I the only one freaked out by that?

Why is Luke's face crossed out?

-Why is my face crossed out?

-Come on...

Let's find the equipment and get out of here.

I'm really sorry, Cat.

Yes!

How'd you find that?

I have an eye for detail. You should know that by how I accessorise.

Great. Now what?

Goodbye, Luke. Ho-ho-ho.

Psst.

-Did you find it?

-No, but we found something else.

'Morning. Time to wake up. All teenagers to the mess immediately.'

Welcome to a new era.

Your test results were so appalling,

we've decided to intensify your curriculum.

By the time we've finished with you,

you will be in peak physical and mental condition.

And have bags under our eyes the size of suitcases. I do not approve.

You think the last few weeks have been tough?

Well, that was just the warm up.

Fuel up! See you outside in half an hour.

I'm not loving the sound of this.

How are we going to see Mac and Skink with my dad watching over us all day?

What are you doing? - Playing him at his own game.

Ah, Lieutenant.

Quarterly audit, have the results on my desk by lunchtime.

It's a bit below me, don't you think?

Alternatively, the bed in the holding cell is still warm.

- Come on. No pain, no gain.

What did Lena mean, "By the time we finish with you"? Are we leaving?

Well, why would we have to be in peak condition?

Yeah. I'm happy as I am, thanks.

They're training us up to be the next soldiers.

-What?

-Think about it.

That's why they brought us here.

When our twins have gone, who's going to fly the next missile?

And Casey was playing good cop to lure us in.

I don't believe my dad would do that to me.

Well, he's doing it to your sister.

We've got to get our twins out of there.

- Less of the chat.

Put those back, refuel, then back outside for orienteering.

Hey! How's it going? Nelly misses you.

She's like, "Ahooo."

Yeah, I should...

-I'll meet you in there.

-Where are you going?

To find out the combination and break into the vault.

How? You can't get into Casey's quarters, they haven't got a key any more.

Cat, you can't. Cat!

- Come on, Lexy. Quick smart.

I know how we get out of the castle - we go underground.

Mate, I'm not digging our way out, not after this mornings torture.

Not dig.

I don't know why we didn't think of this before.

Look, if the rocket really is buried under that island,

there's got to be a way the adults get to it from the SZ.

We don't need a boat.

What about Mac and Skink?

We don't need them either.

Look, we go to the SZ, find our bros, they show us the rocket.

Boom, no more mission. You up for it?

-Would you stop that?

-I'm just saying.

-He's coming, OK?

I can practically hear him running here right now.

-You looking for something?

-Oh, hi.

Eh, yeah, my earring.

I think I dropped it on the way back from Gaia's. Doh, clumsy.

-You should be more careful.

-Yeah.

Anyway, it's nothing important, just sentimental.

I'll help you look.

You see, I'm a sentimental fool myself.

Never like to lose anything.

Cat, if you want my style advice, don't keep me waiting. Come on.

Right. Well, if I do find it, I'll bring it right back.

Thanks.

I think he was threatening me. Don't look.

This is the SZ?

What's everyone raving about? It's tiny.

Yeah, underwhelmed much.

OK, I take it back. Come on.

Let's go wreck a rocket.

-Why did you go on your own?

-I know, I was fired up. I'm sorry.

Anyway, hijacking his equipment is a no-go. We need a new strategy.

Well, even if we did stop him controlling our twins,

how are we going to stop whatever it is he's planning?

Let me have a look at that again.

It's got to be tied in somehow.

When I was down there, they talked about The Origin

and The Object, like it was part of the same thing.

And they do The Origin ceremony around The Object.

Why? What's so special about The Object?

-Exactly.

-What are you thinking?

Well, if we find out why it's so important,

-maybe we also find out how to stop Casey.

-How are we going to do that?

How do you think? We go back down to the SZ and steal it.

-You can't ignore me forever.

-I can and I will until The Origin returns.

Get rid of them.

Where are our brothers?

OK, before you go all sparkly-eyed and try to rip our heads off,

we were hoping that you might be able to show us where the rocket is.

-Titan 2?

-The imposters sent them to sabotage the mission.

-What?

You mean Cat? No.

Look, seriously, Cat doesn't even believe in the whole Titan thing.

I told you, she is one the lies The Origin spoke of. Get rid of them.

No, wait. Why do you want to see Titan 2?

Because we think that if we find...

We think that if we can go back and tell Cat that we've seen it,

then she'll stop banging on about the mission being a lie.

-Mate, I thought we agreed that...

-We don't know where Titan 2 is located.

But we can show you proof that we are going to Titan.

Put these on.

Check me out. I look like a right boffin.

The minute we're out of classes, we go down to the SZ.

Yeah, sounds good to me.

Actually, I was thinking me, Lexy and Luke should go.

All right, children, nap time's over. Grab a compass, grab a map.

This will test your brain and your brawn.

Where's Slim and AJ?

What's up?

-Wow, what is this place?

-The control room.

-We need to access the T1 files.

-The T1 files? But they're classified.

- Yes, they are.

- Please.

-What's he doing?

-These files have a higher level security than others.

You can hack into top level security files? Can you show me?

It's an algorithm. It emulates the system's encryption algorithm.

Wow, found the real boffin. So, what's your superpower?

-What do you mean?

-Well, he's like super brainy and you are...

Super serious? Wow. You two are nothing like us.

We're in.

'Ground Control, this is Commander Lawrence Winters.

'We have landed on Titan. I repeat...

'..mission accomplished.

'We have done it.

'Phase 2 can begin.'

Holy macaroni.

That's from Titan.

- It's the landing log from the first mission 12 years ago.

- Is that enough proof for you?

Hey, Gregor, wait!

-Have I done something to upset you?

-No.

Come on, I thought we were friends.

I heard you talking to Lexy yesterday...

-about me.

-No.

Greg, I'm so sorry. I didn't mean to stick my nose in.

-I know you like Lexy, but she's...

-But I don't. I mean, I did, but...

I like someone else now.

I mean...

really like.

Who?

Hey, can you do me a favour?

Sorry, am I interrupting something?

No, you're all right.

OK. Lawrence Winters' manuscript, can you see

if there's anything like this in it?

I found it in the cave.

I'll show you sometime.

Thanks, man, I owe you.

All right, you lot, inside. Task's over.

I better go.

OK, shower then meet back here in 20.

The sooner we get The Object,

the sooner we can stop Casey and save our twins.

-Nobody move!

-Where have you been?

-Hanging out with our brothers.

-What?

Zip it. You will not believe. Drumroll, please.

The mission to Titan's totally real.

We've seen evidence with our very own eyes.

I didn't find an earring, but I did...

find this...

..in my room.
