0:00:22 > 0:00:23Luke...
0:00:23 > 0:00:26- What have you done to them? Are they dead?- No...- You liar!
0:00:26 > 0:00:29- They're not dead because... - Duncan, no!
0:00:29 > 0:00:32- What choice do we have? - Tell us!
0:00:32 > 0:00:35Because...they were never really alive.
0:00:35 > 0:00:38They're "clo-bots".
0:00:38 > 0:00:40How did you get down here again?
0:00:40 > 0:00:42What are "clo-bots"?
0:00:42 > 0:00:44- Answer me.- No!
0:00:44 > 0:00:46You answer me.
0:00:50 > 0:00:52- You cloned us?- Not exactly, no.
0:00:52 > 0:00:58A clo-bot is basically a unique, high-functioning robot.
0:00:58 > 0:01:03A what? They're made of synthetic cells using human DNA coding.
0:01:03 > 0:01:07- Yeah, OUR DNA.- So they divide and grow just like human cells.
0:01:07 > 0:01:09You stole our DNA?
0:01:09 > 0:01:12They're a magnificent scientific achievement!
0:01:12 > 0:01:15Nobody else in the world has done anything like this.
0:01:15 > 0:01:17Probably because it's illegal.
0:01:17 > 0:01:20They have made a vital contribution to the success of
0:01:20 > 0:01:22our Titan programme.
0:01:22 > 0:01:26These particular clo-bots were due to fly out later on this year
0:01:26 > 0:01:29to help with the preparation at the space station. But now...
0:01:29 > 0:01:32Now the mission has been brought forward.
0:01:32 > 0:01:34They are being fast-tracked ready for the flight.
0:01:34 > 0:01:37Their software is therefore being... upgraded.
0:01:37 > 0:01:40Yes, and that's why they appeared the way they did.
0:01:40 > 0:01:46In any event, they are not your siblings. They are machines.
0:01:46 > 0:01:50They are not machines. Caitlin's more human than you.
0:01:50 > 0:01:52Thank you.
0:01:52 > 0:01:55- So how long will this upgrade take? I still want to see her.- No.
0:01:55 > 0:02:02D-Quadrant remains strictly out of bounds for your own safety.
0:02:02 > 0:02:06Now, we have work to do. Lots of work.
0:02:06 > 0:02:08May I have a word with you, please.
0:02:13 > 0:02:16I'm sure your heads must be spinning.
0:02:16 > 0:02:19- So, have you got any questions? - Clo-bots...- Clo-bots!
0:02:19 > 0:02:22- Do they have any blood? - It's awesome!- It's disgusting.
0:02:26 > 0:02:28What happened to not wanting to lie to the kids?
0:02:28 > 0:02:30- I thought it'd be too much. - I agree.
0:02:30 > 0:02:33Kids don't need to know about Protocol-B till the very last minute.
0:02:33 > 0:02:37- They might be right. We don't want a mutiny on our hands.- Whatever.
0:02:39 > 0:02:41More importantly, we need to find out
0:02:41 > 0:02:43how they're still managing to get down there.
0:02:46 > 0:02:47DOOR OPENS
0:02:50 > 0:02:51You're back early.
0:02:51 > 0:02:53I've been fired.
0:02:53 > 0:02:58- You mean you didn't deliver my note to AJ?- Mum! Are you OK?
0:02:58 > 0:03:02- SHE GASPS - She is so selfish!
0:03:02 > 0:03:04SHE SIGHS
0:03:04 > 0:03:09I saw your face. You're thinking the same as me, right?
0:03:09 > 0:03:10We might be natural twins.
0:03:13 > 0:03:15Or one of us might be a clo-bot.
0:03:20 > 0:03:22If one of us was a machine, we'd know, surely.
0:03:22 > 0:03:25I mean, I've just seen the others rebooting or whatever.
0:03:25 > 0:03:28None of us have ever had to do that.
0:03:28 > 0:03:32How would you feel? If it was you?
0:03:32 > 0:03:33I don't think I can live with it, Luke.
0:03:39 > 0:03:43- Boys... - No. I don't want you to tell us.
0:03:43 > 0:03:48If we don't know, we can carry on, can't we? Like before. Like normal?
0:03:48 > 0:03:50- Let's just hear them out, Noah. - Did you not hear what I just said?!
0:03:50 > 0:03:52I don't want to know!
0:03:56 > 0:03:57Mom?
0:04:08 > 0:04:12- Just when we thought things couldn't get any weirder.- I know.
0:04:12 > 0:04:15Robot versions of ourselves living down in the SZ.
0:04:15 > 0:04:19I feel a bit better about it, now that I know they're not real.
0:04:19 > 0:04:23It means my dad's not as cruel as I was beginning to think he was.
0:04:23 > 0:04:26It's still incredibly cruel, Gaia.
0:04:26 > 0:04:28They've been treated worse than caged animals.
0:04:28 > 0:04:31I suppose when you put it like that...
0:04:31 > 0:04:34Animals are sentient beings.
0:04:34 > 0:04:37These "clo-bot" things are not.
0:04:37 > 0:04:39How can you say that?
0:04:39 > 0:04:43So, how do we all feel about one of them living amongst us?
0:04:43 > 0:04:47- What are you talking about? - She means Noah or Luke.
0:04:47 > 0:04:49What... You think that...?
0:04:49 > 0:04:54- Come on, AJ. Get with the programme. - But... They're both so normal.
0:04:54 > 0:04:56Exactly. And so is my twin.
0:04:56 > 0:04:59- Clo-bot.- Twin.
0:04:59 > 0:05:04She has my DNA, or a version of it, at least. She is not a freak, OK?
0:05:05 > 0:05:07None of them are.
0:05:14 > 0:05:16TEARFULLY: I'm so sorry, Luke.
0:05:22 > 0:05:24It's me. Isn't it?
0:05:26 > 0:05:27It's Noah.
0:05:28 > 0:05:29Noah's the clo-bot.
0:05:31 > 0:05:32Oh, my darling.
0:05:32 > 0:05:35- What're we going to... - Don't touch me.
0:05:35 > 0:05:40I ran away with you both to save him, Luke.
0:05:40 > 0:05:44I lost my home, I lost my job.
0:05:45 > 0:05:47It destroyed our marriage.
0:05:47 > 0:05:49Am I supposed to feel sorry for you?
0:05:49 > 0:05:52No, no, of course not. I'm just trying to explain...
0:05:52 > 0:05:56You were involved, Mom! Just like him and all the others!
0:05:56 > 0:06:00You took our DNA and you made artificial copies of all of us!
0:06:00 > 0:06:02What were you thinking?
0:06:02 > 0:06:06- That we'd save the world. - You'd save the world? Wha...?
0:06:08 > 0:06:13OK, listen. If Noah asks, we're natural twins, got it?!
0:06:13 > 0:06:16- No. He won't believe you.- We make him believe it!- Noah's not stupid.
0:06:16 > 0:06:19- It's bound to come out sooner or later.- Dad, he's my brother.
0:06:19 > 0:06:23I love him and... And I know what this would do to him.
0:06:27 > 0:06:29- Mom. Please. - SHE SOBS
0:06:29 > 0:06:31It makes sense now.
0:06:31 > 0:06:33Why the other Gaia was so cold.
0:06:33 > 0:06:36But then, the other Caitlin was really nice!
0:06:36 > 0:06:38And what about Noah and Luke?
0:06:38 > 0:06:41Lexy says one of them must be a clo-bot.
0:06:42 > 0:06:45- Lexy needs to learn how to keep her mouth shut.- Is it true?
0:06:47 > 0:06:50So, how many times did you meet with the clo-bots?
0:06:50 > 0:06:54- Sounds like you were constantly down there.- Not really. Well, not me.
0:06:54 > 0:06:57But once we found the secret passage from the monument,
0:06:57 > 0:06:59the others were down there quite a lot.
0:06:59 > 0:07:02I wanted to tell you but we didn't know what was going on.
0:07:02 > 0:07:03It's OK.
0:07:03 > 0:07:06Why are we only saving ourselves?
0:07:06 > 0:07:08I still don't understand why someone can't just go speak
0:07:08 > 0:07:10- to someone in the government and... - We tried that.
0:07:10 > 0:07:12Well, why didn't they listen?
0:07:12 > 0:07:16Because mirror-matter theory is just that. It's a theory.
0:07:16 > 0:07:20The ACT's not taken as serious as it should be. Never has been.
0:07:20 > 0:07:23I mean, governments are now tracking the original asteroid we discovered,
0:07:23 > 0:07:27- but as for this one...- Well, why don't we just go to the papers?
0:07:27 > 0:07:29HE SIGHS It's not as simple as that, Gaia.
0:07:29 > 0:07:31Trust me.
0:07:31 > 0:07:33I wish it was.
0:07:44 > 0:07:46- What are you doing? - Looking for Dad's phone.
0:07:46 > 0:07:48If I can't see Mackenzie, then I'll call her.
0:07:48 > 0:07:51Mmm, he always has his phone with him.
0:07:51 > 0:07:53I'll use the one in the office then.
0:07:53 > 0:07:55Respect! Hey, wait up!
0:07:55 > 0:07:58There's a few phone calls I'd like to make while we're at it.

0:08:26 > 0:08:28Mom's telling him we're natural twins.
0:08:30 > 0:08:32Promise me you won't say anything, Cat? Please?
0:08:35 > 0:08:36It'll kill him.
0:08:40 > 0:08:41OK.
0:08:41 > 0:08:43Cat! Cat! We need you.
0:08:53 > 0:08:54All clear.
0:08:55 > 0:08:58- Lexy, you scared us. - What are you all doing?
0:08:58 > 0:09:01- What does it look like? - Phoning our friends and family.
0:09:01 > 0:09:05And the government. We're going to let the world know what's happening.
0:09:05 > 0:09:09- I don't have anyone to call. - Me neither.
0:09:09 > 0:09:11- AJ GASPS - Whoa... I'm going first!
0:09:11 > 0:09:13MY call's more important, AJ!

0:09:27 > 0:09:29We've all been stopped from leaving the castle.
0:09:29 > 0:09:30- MACKENZIE:- We gathered that much.
0:09:30 > 0:09:32Gregor said we should try signalling you,
0:09:32 > 0:09:35so we tried to send for you with Mum's curtains, but it's really...
0:09:35 > 0:09:38- Shut up a minute, will you! - Did you just tell me to shut up?
0:09:38 > 0:09:39- AJ:- I'm sorry, it's just...
0:09:39 > 0:09:42Look, I haven't got long and there's something really,
0:09:42 > 0:09:44- really important I need to tell you.- AJ...?

0:09:51 > 0:09:54- Do you WANT to cause a worldwide panic?- We were trying...- Silence!
0:09:54 > 0:09:57This is the reason we've kept things from you for so long.
0:09:57 > 0:09:59You cannot be trusted.
0:09:59 > 0:10:00Any of you.
0:10:02 > 0:10:05Mackenzie, snap out of it and tell us what he just said!
0:10:06 > 0:10:08I think...
0:10:08 > 0:10:10I think he was about to propose.

0:10:26 > 0:10:28Haven't seen you all morning.
0:10:28 > 0:10:30I've just been trying to get my head together.
0:10:30 > 0:10:32- CAT SIGHS - Tell me about it.
0:10:32 > 0:10:35I guess there's a lot of gossip, right?
0:10:35 > 0:10:38- About who's the clo-bot. - No.
0:10:38 > 0:10:40Well, not much.
0:10:42 > 0:10:46Well, according to Luke, Mom swears we're natural twins.
0:10:46 > 0:10:50- That's great. - She's lied to us before, Cat. So...
0:10:50 > 0:10:53I don't know what to believe, I...
0:10:53 > 0:10:54I guess it could be possible.
0:10:55 > 0:10:59Noah, hey... I'm sorry. But I, um...
0:11:00 > 0:11:04- ..I need to get my own head together right now.- Oh, of course.
0:11:04 > 0:11:07- Sorry, that was selfish. - No! It's not.
0:11:07 > 0:11:11It's just...everything is so messed up.
0:11:11 > 0:11:13For all of us.
0:11:14 > 0:11:16Talk later, yeah?

0:11:25 > 0:11:28Even if they can see us here, which I doubt,

0:11:30 > 0:11:32WE don't even know what we're trying to say!
0:11:32 > 0:11:36I know what I'm trying to say - yes! It's one word, how hard can it be!
0:11:36 > 0:11:38Morse code might be easier.
0:11:38 > 0:11:41Oh, the funny dancing thing with the wee bells?
0:11:41 > 0:11:43That's Morris dancing.
0:11:43 > 0:11:46Morse code? Dot-dot-dot? Dash-dash-dash?
0:11:46 > 0:11:50I've got a book on it. We could meet at the cafe tomorrow morning
0:11:50 > 0:11:52- and try learning that instead? - I can't wait that long!
0:11:52 > 0:11:55AJ might change his mind by then, you know what boys are like.
0:11:55 > 0:11:57Have you got a better idea?
0:11:57 > 0:12:01- MACKENZIE SIGHS - Fine. Dot-dot-dash it is.
0:12:03 > 0:12:05SHE SIGHS
0:12:08 > 0:12:13- Luke.- Hi.- I spoke to Noah earlier.
0:12:13 > 0:12:16- I'm really not happy about lying to him.- We don't have a choice.
0:12:16 > 0:12:18You can't protect him for ever.
0:12:18 > 0:12:19I'm going to try!
0:12:21 > 0:12:23I have to, Cat.
0:12:23 > 0:12:26Hey. Come here.
0:12:30 > 0:12:33- What's going on?- Hey, bro!
0:12:33 > 0:12:35- So when did you two become an item? - We're not!
0:12:35 > 0:12:37- You've got that wrong!- Were you even going to tell me?- No...
0:12:37 > 0:12:40I thought all that, "We're practically boyfriend and girlfriend"
0:12:40 > 0:12:43- stuff was just a joke? - It was. Noah...- Forget it.
0:12:43 > 0:12:45I wasn't that into you anyway.
0:12:47 > 0:12:49It's OK, I'll sort it.
0:12:51 > 0:12:52Why're you behaving like an idiot?
0:12:52 > 0:12:55You knew I liked her but you muscled in anyway!
0:12:55 > 0:12:58- What kind of brother does that? - She was giving me a friendly hug! - Yeah, right(!)
0:12:58 > 0:13:02- She heard the rumours and wanted us to know she's there for us.- Liar.
0:13:02 > 0:13:06- There's nothing going on!- What else are you lying to me about, huh?
0:13:06 > 0:13:09- Nothing!- Have you even told me the truth about what Mom said?- Yeah!
0:13:09 > 0:13:12Are you sure she didn't tell you which one of us was the clo-bot?
0:13:12 > 0:13:16- We're natural twins, I told you. - It's me, isn't it?- Noah...
0:13:16 > 0:13:17It is.
0:13:17 > 0:13:20I know it is. And what? That gives you the right to take my girl?
0:13:20 > 0:13:23- Calm down!- I'm not entitled to a normal life any more, is that it?!
0:13:23 > 0:13:25- Now that I'm officially a freak? - Listen to yourself!
0:13:25 > 0:13:28- You're talking crazy, man! - Tell me I'm wrong!- Stop it.
0:13:28 > 0:13:30- N-no, tell me!- Noah... - Tell me I'm wrong, Luke!
0:13:30 > 0:13:32You're wrong, OK!
0:13:32 > 0:13:34It's me! I'm the clo-bot!
0:13:36 > 0:13:38You?
0:13:38 > 0:13:40No... I don't believe you.
0:13:40 > 0:13:42- Have I ever lied to you before? - Swear!
0:13:44 > 0:13:45I swear.
0:13:47 > 0:13:49Luke...
0:13:49 > 0:13:51So sorry, man.
0:13:51 > 0:13:52It's OK.
