0:00:15 > 0:00:17You're going to a...
0:00:17 > 0:00:19a where?
0:00:19 > 0:00:20To Titan.
0:00:20 > 0:00:23- Titan? Where's Titan? - It's to be our new home.
0:00:23 > 0:00:25- And who told you that?- The Origin.
0:00:25 > 0:00:26Did they say why?
0:00:26 > 0:00:29ALL: We are pioneers. We are special.
0:00:29 > 0:00:32We need sleep. Tomorrow's a big day.
0:00:35 > 0:00:37What happens tomorrow?
0:00:38 > 0:00:41Tomorrow, we summon The Origin.
0:00:42 > 0:00:44DOG BARKS, TALK OVER RADIO
0:00:49 > 0:00:51Steph?
0:00:52 > 0:00:55Can you do me a favour and come and double-check these?
0:01:05 > 0:01:07You're right.
0:01:13 > 0:01:15How well do you two get on with AJ?
0:01:15 > 0:01:17It's just he's got one of those Pictish balls I told you about.
0:01:17 > 0:01:19Could really use it for my research.
0:01:19 > 0:01:21Wondered what his price might be.
0:01:21 > 0:01:24- I'll ask him.- Thanks, mate.- Yeah.
0:01:26 > 0:01:29Hey, if I was looking to buy that ball,
0:01:29 > 0:01:31what kind of price would I be looking at?
0:01:31 > 0:01:35It's not for sale! Mackenzie would skin me alive if I got rid of it.
0:01:36 > 0:01:39You know this is the first thing she's ever given me?
0:01:39 > 0:01:41It's like a millstone in our relationship.
0:01:41 > 0:01:44- I think you mean milestone. - No, he was right the first time.
0:01:44 > 0:01:47That thing's got massive strings attached to it.
0:01:47 > 0:01:50Hey, good luck getting your dad to agree to lunch!
0:01:50 > 0:01:52HE LAUGHS
0:01:52 > 0:01:54Don't eat it!
0:01:54 > 0:01:55Dad, can I have a word?
0:01:55 > 0:01:57- Not right now.- Wait, it's urgent.
0:01:57 > 0:02:00- Can I have a look? - It's not that interesting.
0:02:02 > 0:02:04We're in the middle of vital defence work here, AJ.
0:02:04 > 0:02:06I don't have time to traipse down to the village to play
0:02:06 > 0:02:08tea parties with a schoolgirl.
0:02:08 > 0:02:11Well, I wasn't asking you to play "tea parties."
0:02:11 > 0:02:12I was asking you to be a good dad.
0:02:15 > 0:02:16AJ.
0:02:17 > 0:02:19Half an hour, that's all.
0:02:19 > 0:02:21Where's Lieutenant Winters?
0:02:22 > 0:02:23AJ.
0:02:25 > 0:02:28Sorry, I slept through the alarm. Have I missed training?
0:02:28 > 0:02:30Did the mentors notice?
0:02:30 > 0:02:32We do not train before the summon.
0:02:33 > 0:02:35ALL: We thank you, Origin,
0:02:35 > 0:02:39ancient and wise, for teaching us the ways of the universe.
0:02:39 > 0:02:43We thank you, Origin, for the wondrous object,
0:02:43 > 0:02:45the oracle of our destiny.
0:02:45 > 0:02:49We thank you. We thank you. We thank you.
0:02:56 > 0:02:57HE TAPS ON WALL
0:02:59 > 0:03:01What are you doing?
0:03:01 > 0:03:05It's how we contact each other when one of us is up there.
0:03:05 > 0:03:08It's time for Caitlin to return.
0:03:08 > 0:03:11The Origin would be displeased if he finds out she is not here.
0:03:14 > 0:03:16Mm, the food we get is nothing like this.
0:03:16 > 0:03:18TAPPING FROM BEHIND WALL
0:03:18 > 0:03:20Shouldn't we be going? We'll be late.
0:03:20 > 0:03:24No, it's private study time. It doesn't really matter if we're late.
0:03:28 > 0:03:29She's not responding.
0:03:31 > 0:03:33You know, it doesn't look like Caitlin's going to be coming
0:03:33 > 0:03:35back any time soon.
0:03:35 > 0:03:37I would love to meet The Origin
0:03:37 > 0:03:41and thank whoever it is for looking after my sister for all these years.
0:03:43 > 0:03:46We thank you, Origin, ancient and wise.
0:03:53 > 0:03:55You'll need these.
0:03:59 > 0:04:02Hey, can I borrow the ball for a couple of hours?
0:04:02 > 0:04:03I just want to check something out.
0:04:03 > 0:04:06I've already told Noah, it's not for sale.
0:04:06 > 0:04:09Borrow, not buy.
0:04:09 > 0:04:11I'll guard it with my life. I promise.
0:04:11 > 0:04:12Please?
0:04:15 > 0:04:17- HE SIGHS - Just be careful.- Thanks.
0:04:17 > 0:04:19What information does it give you?
0:04:19 > 0:04:21Erm, none.
0:04:21 > 0:04:24It's just a made-up story and an overly sentimental one at that.
0:04:27 > 0:04:30Caitlin, you know you said you didn't have any toys
0:04:30 > 0:04:31when you were little?
0:04:31 > 0:04:34Well...I want you to have this.
0:04:34 > 0:04:37- Oh, no, I couldn't. - I've always hated it.
0:04:37 > 0:04:41I just don't like the idea that you didn't have any toys...
0:04:41 > 0:04:43or that Alexa didn't.
0:04:44 > 0:04:46What was she like?
0:04:46 > 0:04:50All I can remember is that she was very kind...
0:04:51 > 0:04:53..just like you.
0:04:55 > 0:04:57Want to know about the world?
0:04:57 > 0:04:58Better get reading.
0:05:01 > 0:05:04My mum caught her in the cafe, scrounging for scraps.
0:05:04 > 0:05:07Said she had to go. Thought maybe you could keep her here.
0:05:09 > 0:05:11I don't think my dad would go for that.
0:05:13 > 0:05:16Actually...I've followed him around my whole life.
0:05:16 > 0:05:18He owes me.
0:05:18 > 0:05:19What do you reckon, Nellie, eh?
0:05:19 > 0:05:21Do you want to come and live here with us?
0:05:21 > 0:05:23Nellie?
0:05:23 > 0:05:25It's my mum's name, Eleanor,
0:05:25 > 0:05:27but everyone called her Nell.
0:05:27 > 0:05:28Come on, Nellie.
0:05:28 > 0:05:32Come on, I'll show you around where you're going to live now. Come on.
0:05:36 > 0:05:39It's my mum's never-know-when outfit. How do I look?
0:05:39 > 0:05:41- SHE LAUGHS - Perfect.
0:05:41 > 0:05:42SHE SQUEALS
0:05:43 > 0:05:46I said swans, not lumps! DOOR OPENS
0:05:46 > 0:05:48I said yes to 100 quid and I didn't get that either!
0:05:48 > 0:05:51Casey, call me back. I've left five voicemails. Where are you?
0:05:51 > 0:05:53Dad.
0:05:53 > 0:05:54Scram!
0:05:54 > 0:05:56MUSIC: True by Spandau Ballet
0:05:56 > 0:05:58Hello, Mr Javadi.
0:05:58 > 0:05:59Major.
0:06:01 > 0:06:03Please...do have a seat.
0:06:04 > 0:06:06Dad.
0:06:06 > 0:06:09I thought we should get to know each other, seeing as, you know,
0:06:09 > 0:06:11we didn't exactly get off to the best start!
0:06:11 > 0:06:15Still, the less said about the whole fire thing, the better, eh?

0:06:32 > 0:06:34WAVES CRASH, SEAGULLS CAW
0:07:04 > 0:07:06And everyone was like, "It's Mrs McGonagall's dog,"
0:07:06 > 0:07:08but the footprints were...
0:07:08 > 0:07:09I swear!
0:07:09 > 0:07:12Oh, that stuff gets everywhere. So, anyway, I was thinking,
0:07:12 > 0:07:15my brain's hard-wired for military research.
0:07:15 > 0:07:18I can spot a yeti from a mile off and a selkie.
0:07:18 > 0:07:20Well, selkies, I'd probably need to be a bit closer,
0:07:20 > 0:07:23but, if you're ever recruiting, I'm totally in.
0:07:24 > 0:07:26Right. It's been enlightening,
0:07:26 > 0:07:27but I've got serious work to get back to.
0:07:27 > 0:07:29No, wait!
0:07:29 > 0:07:31I wanted you to hear this.
0:07:34 > 0:07:36# I wrote this for my boyfriend's dad
0:07:36 > 0:07:38# Whose first impression was I'm bad
0:07:38 > 0:07:40# I know I sometimes do mad things
0:07:40 > 0:07:42# But that's because of just one thing
0:07:42 > 0:07:45# My head and heart are totes doolally
0:07:45 > 0:07:48# Cos I've lost them both to AJ Javadi. #
0:07:48 > 0:07:50And before you all go, "Oh, that's rubbish,"
0:07:50 > 0:07:53it's really hard to find a word that rhymes with Javadi.
0:07:57 > 0:07:58I have to go.
0:07:59 > 0:08:01Yes!
0:08:02 > 0:08:03A swan!
0:08:07 > 0:08:09Wow. You're a fast reader.
0:08:11 > 0:08:15Lexy said that there are made-up things in your books.
0:08:16 > 0:08:18Is this a made-up thing?
0:08:18 > 0:08:20No, but I can see why you think that.
0:08:23 > 0:08:27That tapping noise this morning, that was for you, wasn't it?
0:08:28 > 0:08:30They wanted me to go back.
0:08:30 > 0:08:32- Why? Is Cat OK?- She's fine.
0:08:32 > 0:08:34Adam will look after her.
0:08:34 > 0:08:36Adam? Why Adam?
0:08:37 > 0:08:40He...cares about me.
0:08:40 > 0:08:43Until now, we've never spent a day apart.
0:08:43 > 0:08:46He's the only thing I miss about that place.
0:08:46 > 0:08:50So, The Origin, is it some kind of God?
0:08:50 > 0:08:52The Origin is our leader.
0:08:54 > 0:08:55Your leader?
0:09:07 > 0:09:09Adam?

0:09:44 > 0:09:47I've been doing this job for years. Those results are indisputable.
0:09:47 > 0:09:49- Dad!- (Not now.)
0:09:50 > 0:09:52Er, fine. I'm on my way.
0:09:55 > 0:09:57We'll talk about that later.
0:09:59 > 0:10:05Gaia, I know I'm not supposed to ask, but what is going on around here?
0:10:05 > 0:10:08If I tell you something, you have to promise not to tell anyone.
0:10:08 > 0:10:09Cross my heart.
0:10:11 > 0:10:13A few days ago,
0:10:13 > 0:10:17I found a secret area hidden underneath the castle and there's
0:10:17 > 0:10:20a lab there, and scientists, and all these weird symbols everywhere.
0:10:20 > 0:10:24- What?- Whatever's going on down there, all our parents are keeping it
0:10:24 > 0:10:27top secret and they won't tell us the truth about anything.
0:10:27 > 0:10:30- Have you called the police? - No, and you can't either.
0:10:30 > 0:10:31The centre would just cover it up.
0:10:31 > 0:10:34Please, please don't tell the others that I told you,
0:10:34 > 0:10:36or our mums and dads. They can't know we know.
0:10:36 > 0:10:38I won't tell, I promise.
0:10:39 > 0:10:42- Just so long as you're all right. - Thank you.

0:12:00 > 0:12:03What's with all the voicemails? I am entitled to the odd day off.
0:12:03 > 0:12:05Casey, it's coming.
0:12:05 > 0:12:07We have a revised ETA.
0:12:07 > 0:12:09I need you to instigate Protocol B.
0:12:10 > 0:12:13- No, I can't. - I gave you fair warning.
0:12:13 > 0:12:16Fair warning is years, not days.
0:12:16 > 0:12:19Stand them down, that's an order.
0:12:19 > 0:12:21All right, everyone, back to work.
0:12:21 > 0:12:23Not just yet. We've got other problems.
0:12:23 > 0:12:26AJ's gone and got himself a scraggy girlfriend.
0:12:26 > 0:12:28And Gaia's got herself a scraggy dog.
0:12:28 > 0:12:31I said they'd start putting roots down if we let them out.
0:12:31 > 0:12:34Maybe it's time to prepare them, too.
