0:00:32 > 0:00:35You're watching me sleep?
0:00:35 > 0:00:36That's creepy.
0:00:36 > 0:00:39It doesn't change anything, you know.
0:00:39 > 0:00:42- You being a...- A clobot?
0:00:42 > 0:00:43Yeah.
0:00:43 > 0:00:45I know.
0:00:47 > 0:00:50This stays between you and me, OK?
0:00:50 > 0:00:53- No-one else needs to know. - Of course.
0:00:57 > 0:01:01The atmosphere on earth is predominantly nitrogen and oxygen,
0:01:01 > 0:01:04the atmosphere on Titan is predominantly nitrogen and methane.
0:01:04 > 0:01:07So, they're sending us to a world that smells like farts.
0:01:07 > 0:01:08Thanks a bunch(!)
0:01:08 > 0:01:11It'll just smells like your side of the bedroom then,
0:01:11 > 0:01:13- you'll feel right at home.- Silence.
0:01:13 > 0:01:15- GAIA LAUGHS - I said silence!
0:01:15 > 0:01:17You're late.
0:01:17 > 0:01:19What is that thing? I saw something like that at the lab.
0:01:19 > 0:01:20Are our twins...?
0:01:20 > 0:01:22I mean... The clobots joining us?
0:01:22 > 0:01:24We told you, they're upgrading.
0:01:24 > 0:01:27Yeah, well, for advanced machinery, they take a long time to upgrade.
0:01:27 > 0:01:31Caitlin, your time would be better spent focusing on human survival,
0:01:31 > 0:01:33not clobot revival.
0:01:33 > 0:01:35They're of no significance to you.
0:01:35 > 0:01:37Sit down!
0:01:37 > 0:01:41This morning I'm going to be talking to you about re-acclimatisation.
0:01:41 > 0:01:44Pay very close attention.
0:01:44 > 0:01:46SHE CONTINUES
0:01:46 > 0:01:49Do you think they know which one of them's the clobot version?
0:01:50 > 0:01:52They're talking about us.
0:01:53 > 0:01:54Just ignore them.
0:01:57 > 0:02:01PHONE RINGS
0:02:03 > 0:02:05Hello?
0:02:06 > 0:02:08What?
0:02:11 > 0:02:13Gregor...
0:02:13 > 0:02:15Gregor!
0:02:15 > 0:02:17Oh, no, no, no, no, no, no.
0:02:17 > 0:02:21Can you just please wait? I'll be right there.
0:02:21 > 0:02:22- Where's Gregor? - We've been waiting on him.
0:02:22 > 0:02:25Oh, no, no, no. Girls, you need to get out.
0:02:25 > 0:02:26Eh, Gregor's Mum, here's some feedback -
0:02:26 > 0:02:28that's terrible customer service.
0:02:28 > 0:02:31Here, just...you can lock up on your way out, OK?
0:02:31 > 0:02:34Wait, where's Gregor? We're supposed to meet him here?
0:02:34 > 0:02:36I've got to get my answer to AJ.
0:02:36 > 0:02:38Guitar lesson, he'll be back soon.
0:02:40 > 0:02:42DOOR CHIME DINGS
0:02:42 > 0:02:45Carrot cake or black forest gateau?
0:02:45 > 0:02:47Oh, carrot cake, please.
0:02:53 > 0:02:56The clobots were due to change the colony's climate ahead of
0:02:56 > 0:03:00human arrival, that responsibility obviously now falls on us.
0:03:00 > 0:03:03So, why bother using the clobots in the first place?
0:03:03 > 0:03:06Cos they can breathe both oxygen and methane.
0:03:06 > 0:03:09They were also built to withstand extreme temperatures, we're not.
0:03:09 > 0:03:10KNOCK ON DOOR
0:03:10 > 0:03:12Excuse me.
0:03:14 > 0:03:18Hey, so that's how Evil Gaia must have escaped the fire!
0:03:18 > 0:03:20Oh... How cool is that?!
0:03:20 > 0:03:22Guys, did you hear that?
0:03:22 > 0:03:24One of you must be made of like, Teflon.
0:03:24 > 0:03:27We haven't been gossiping, honestly, we're just curious.
0:03:27 > 0:03:29- (Hey, mouth!) - GAS HISSES
0:03:29 > 0:03:32- ALL: Whoa! - Sorry.- What are you doing?!
0:03:32 > 0:03:35- Seeing which one of you breathes methane.- You're pathetic.
0:03:35 > 0:03:37Neither of us can breathe methane, we're natural twins.
0:03:37 > 0:03:40- Yeah, right, and so are me and Slim. Who told you that?- Our mum and dad.
0:03:40 > 0:03:43Well, I'd say they were lying and they've all got form on that front.
0:03:43 > 0:03:45Leave it, Lexy!
0:03:45 > 0:03:48If one of you really is a clobot, then you'd be fireproof, right?
0:03:48 > 0:03:50- No, no, no.- AJ!- AJ, no!
0:03:50 > 0:03:53What on earth do you think you're doing?!
0:03:53 > 0:03:55We want to know which one of them's a clobot.
0:03:55 > 0:03:57By burning them?
0:03:57 > 0:03:59Ridiculous and dangerous.
0:03:59 > 0:04:00OK, this has gone far enough.
0:04:00 > 0:04:02If you really must know...
0:04:02 > 0:04:04Right, it's me, OK? I'm the clobot.
0:04:09 > 0:04:11There we are, then.
0:04:11 > 0:04:14Now, can we please get on with learning how to survive?
0:04:16 > 0:04:18Do you thrive on deceit?
0:04:18 > 0:04:20What is it?
0:04:20 > 0:04:23The thrill of knowing that, at any moment, you might get found out?
0:04:23 > 0:04:25What are you talking about, Lena? I'm busy.
0:04:25 > 0:04:27- Luke, claiming to be the clobot. - You what?
0:04:27 > 0:04:29Presumably you put him up to it to protect Noah.
0:04:29 > 0:04:33- No, I didn't.- You told me that he thought they were natural twins -
0:04:33 > 0:04:36an equally stupid lie in my opinion.
0:04:36 > 0:04:38Do you really think that Luke can keep up this facade
0:04:38 > 0:04:39for the rest of his life?
0:04:39 > 0:04:41You should have left Noah where he was.
0:04:41 > 0:04:44What you're doing is cruel to both of them.
0:04:44 > 0:04:47I don't think you have any right to talk about cruelty, Lena.
0:04:52 > 0:04:54- LENA SLAMS DOOR - Thank you.
0:04:56 > 0:04:59Dude, why did you tell everybody? I thought we agreed?
0:04:59 > 0:05:01I know.
0:05:01 > 0:05:05- Yeah, you really didn't have to do that.- I kind of did.
0:05:05 > 0:05:08They weren't going to let up till they found out. I mean...
0:05:18 > 0:05:22So, how different do you think the clobots really are from us?
0:05:22 > 0:05:26I mean, they're like robots but they digest food.
0:05:27 > 0:05:31So do they...you know?
0:05:31 > 0:05:33Poo!
0:05:33 > 0:05:35Luke does poo, right?
0:05:35 > 0:05:37Eugh, AJ, that's gross!
0:05:38 > 0:05:41- So, do they have like, synthetic bowels?- AJ!
0:05:41 > 0:05:44Have they got like, metal bones and stuff?
0:05:44 > 0:05:45What?
0:05:46 > 0:05:49Lena told us about your announcement.
0:05:49 > 0:05:52- Luke, I thought we'd agreed. - I didn't have a choice.
0:05:52 > 0:05:55- Of course you did. - I didn't!
0:05:56 > 0:05:59And I wouldn't expect you to understand.
0:05:59 > 0:06:01Family meeting?
0:06:01 > 0:06:04Uh, yes. I was just saying that Lena told us about Luke's announcement
0:06:04 > 0:06:09and I was just checking that you're both OK with it really.
0:06:09 > 0:06:10I guess. Luke?
0:06:13 > 0:06:16Yeah, I'm OK.
0:06:16 > 0:06:17That's good.
0:06:23 > 0:06:27So, they're flame busters and they breathe like
0:06:27 > 0:06:30fart gas, but what else can they do that we can't?
0:06:32 > 0:06:36I know. How about we put it to the test?
0:06:36 > 0:06:38Put what to the test?
0:06:38 > 0:06:42We want to know what makes us different to the clobot.
0:06:42 > 0:06:46Think of it as a friendly duel - man vs machine.
0:06:46 > 0:06:49This is stupid. Don't let them do this to you, guys.
0:06:49 > 0:06:53No, do. I want to know exactly what a clobot is capable of.
0:06:53 > 0:06:54THEY GIGGLE
0:06:54 > 0:06:56I'm down. Luke?
0:06:57 > 0:06:59Sure.
0:07:02 > 0:07:04So, the tests are...
0:07:04 > 0:07:08memory, strength, intelligence and dexterity.
0:07:08 > 0:07:11Test number one, memory.
0:07:12 > 0:07:15Soap, bike horn, box, creepy doll, flashlight, ball,
0:07:15 > 0:07:18camera, book, spinning top, clock.
0:07:20 > 0:07:25Camera, soap, flashlight, book, bike horn, spinning top, soap...
0:07:25 > 0:07:27Said that!
0:07:27 > 0:07:32Um...box. Uh, clock, ball...
0:07:32 > 0:07:35Creepy doll. Yes, 10/10.
0:07:37 > 0:07:39Test number two - strength.
0:07:47 > 0:07:48Yes!
0:07:48 > 0:07:50One-all!
0:07:53 > 0:07:57Test number three - intelligence and dexterity.
0:07:57 > 0:08:01Ye-es, the task-meister's found the perfect little puzzle
0:08:01 > 0:08:04to test both of these skills at once.
0:08:04 > 0:08:06Ta-da! Ha-ha.
0:08:06 > 0:08:09Well, it takes days for any normal human to complete. Sorry, Noah.
0:08:09 > 0:08:12But, Luke, if you're a robot worthy of your name,
0:08:12 > 0:08:13you'll do it in minutes.
0:08:14 > 0:08:17Yeah.
0:08:17 > 0:08:18HE CLEARS THROAT
0:08:21 > 0:08:25This is a lot of pressure with you all staring at me.
0:08:25 > 0:08:26HE CLEARS THROAT AGAIN
0:08:26 > 0:08:28Lunch time!
0:08:28 > 0:08:29I'm starving.
0:08:29 > 0:08:32We can come back later. Come on.
0:08:32 > 0:08:33But we...
0:08:33 > 0:08:37- I'm actually pretty hungry. - And I'm totally bored.
0:08:37 > 0:08:38Mate!
0:08:38 > 0:08:41What day is it? Steak sandwich day!
0:08:43 > 0:08:45You coming?
0:08:45 > 0:08:47Oh, no. I'll be down in a bit.
0:08:49 > 0:08:52If I just found out the brother I grew up with was a robot,
0:08:52 > 0:08:54I'd need some alone time too.
0:08:55 > 0:08:57I mean...
0:08:57 > 0:09:00Not that I think of Luke as a robot. I just...
0:09:14 > 0:09:17Grim. Should have stopped at two slices.
0:09:18 > 0:09:20You've got to be kidding.
0:09:20 > 0:09:23Erm, we were cake sampling for my wedding.
0:09:23 > 0:09:25Just pay up or get out.
0:09:26 > 0:09:29- Guess we better get out then. - Erm, not so fast.
0:09:29 > 0:09:32We've been waiting, like, all day for Gregor to finish his guitar lesson.
0:09:34 > 0:09:35Eh...
0:09:35 > 0:09:37Mackenzie,
0:09:37 > 0:09:40since when does Gregor go to guitar lessons without his guitar?
0:09:42 > 0:09:44BOTH: What's going on?
0:09:44 > 0:09:49- I forgot, he's actually at his dad's.- What, like, for good?- No!
0:09:49 > 0:09:51He will be back soon.
0:09:51 > 0:09:53KEYS CLATTER
0:09:55 > 0:09:58What's up with her?
0:09:58 > 0:09:59Gregor's mum, you sneaky minx!
0:09:59 > 0:10:00What?
0:10:00 > 0:10:03She's only got herself a secret boyfriend and packed Gregor off
0:10:03 > 0:10:05so she can do some sly smooching.
0:10:05 > 0:10:07You're totally right, sneaky minx.
0:10:07 > 0:10:09I wish I could do some sly smooching.
0:10:18 > 0:10:19No.
0:10:19 > 0:10:21I didn't even say anything.
0:10:21 > 0:10:24Let me guess, "Please, can I go and see Mackenzie?"
0:10:25 > 0:10:27That's frightening.
0:10:28 > 0:10:32I know it's cruel, son, but my advice?
0:10:32 > 0:10:34Forget about her.
0:10:37 > 0:10:39I'm going to take these up for Noah.
0:10:51 > 0:10:52Thought you might be hungry.
0:10:52 > 0:10:54Thanks.
0:10:56 > 0:11:00Noah, about last night.
0:11:00 > 0:11:02- Me and Luke, we're not...- I know.
0:11:03 > 0:11:04How did...?
0:11:04 > 0:11:08How did you feel when you found out your sister wasn't real?
0:11:08 > 0:11:11Did it change things?
0:11:11 > 0:11:12She's still real to me.
0:11:14 > 0:11:16It's going to be OK, Noah.
0:11:16 > 0:11:19You and Luke, you've always been brothers.
0:11:19 > 0:11:21It's not going to change.
0:11:22 > 0:11:24What are you...?
0:11:25 > 0:11:27- I should...- No, Cat.
0:11:27 > 0:11:28Wait.
0:11:30 > 0:11:32Tell me the truth.
0:11:32 > 0:11:34Please?
0:11:36 > 0:11:38Am I the clobot?
0:11:39 > 0:11:41Noah, don't be...
0:11:45 > 0:11:46Thought you might be hungry.
