0:00:15 > 0:00:16Lockdown! Everyone to quarters now!
0:00:16 > 0:00:18ALARM BEEPS
0:00:18 > 0:00:21- What about us? - We've got to get out of here.
0:00:23 > 0:00:27- If the outer zone has already been breeched, we could be too late.
0:00:30 > 0:00:32Don't be afraid. It's me.
0:00:34 > 0:00:37I am The Origin, your leader.
0:00:37 > 0:00:38It's not working.
0:00:38 > 0:00:41- He's been a Loose Cannon for quite some time, Adam.
0:00:41 > 0:00:43I've been protecting him.
0:00:45 > 0:00:47- It's time to fulfil your destiny.- Now?
0:00:47 > 0:00:50- You must obey me. - We are ready.- Follow me.
0:00:50 > 0:00:53- Arrest him!- Not so fast, Casey. - No, you can't do this.
0:00:55 > 0:00:58- No, he's The Origin! - I believe in you. Still have faith.
0:00:58 > 0:01:00The Origin will return! Get off!
0:01:00 > 0:01:02Get to your rooms, please.
0:01:04 > 0:01:07- Where's Catlin?- Here. - Get to your room now.
0:01:09 > 0:01:10Do it.
0:01:16 > 0:01:20- Why are you locking us in? - For your own safety.
0:01:34 > 0:01:36He was right there...
0:01:36 > 0:01:39just staring at me.
0:01:40 > 0:01:44I really thought I was a goner, Noah.
0:01:44 > 0:01:45You're safe now.
0:01:55 > 0:01:59I hope Luke's OK...and Lexy.
0:01:59 > 0:02:00And my sister.
0:02:10 > 0:02:12Please can we go? I hate this place.
0:02:20 > 0:02:22Where did everyone disappear to?
0:02:29 > 0:02:31You think it'd be crawling with guards.
0:02:31 > 0:02:35Maybe the alarm was nothing to do with us taking the object.
0:02:35 > 0:02:38I say we go, before it really is missed.
0:02:45 > 0:02:51These look a bit similar. Then again, it could just be Lawrence's doodles.
0:02:51 > 0:02:55That looks like an upside down L or a T.
0:02:55 > 0:02:57Oi, anyone serving in here?
0:02:57 > 0:03:00Sorry, yes. What can I get you?
0:03:00 > 0:03:03What is it that's so interesting anyway?
0:03:03 > 0:03:06Oh, is it a code? I'm good at codes.
0:03:06 > 0:03:08AJ, come over here and help.
0:03:08 > 0:03:11Eh, thanks, Mackenzie, but I think we're doing OK actually.
0:03:11 > 0:03:13Skink, you too.
0:03:15 > 0:03:19Oh, is it a crossword? I hate crosswords.
0:03:19 > 0:03:21Can I borrow this?
0:03:21 > 0:03:23Hey, I hope you're going to pay for that.
0:03:23 > 0:03:25Look at this.
0:03:25 > 0:03:29- It's a mirror image. - Oh, yeah, they're letters.
0:03:29 > 0:03:31A-C-T. Act?
0:03:31 > 0:03:33- Oh, it's one of those anagrams!
0:03:33 > 0:03:35- Acronyms.
0:03:35 > 0:03:36- That's what I said.
0:03:36 > 0:03:39I can't believe how small he was.
0:03:39 > 0:03:40Catlin was right -
0:03:40 > 0:03:43he's just an ordinary man.
0:03:43 > 0:03:44What about the mission?
0:03:44 > 0:03:45Is he still our leader?
0:03:45 > 0:03:49How can he be? They placed him under arrest.
0:03:49 > 0:03:53Of course he's our leader. Did you not hear what he said? "Have faith."
0:04:13 > 0:04:16Alien conference tonight?
0:04:16 > 0:04:19All clear, Thomas?
0:04:20 > 0:04:22- Who's Thomas?- Timothy?
0:04:22 > 0:04:24Maybe it just means act,
0:04:24 > 0:04:29like "act now," "act one," "act silly."
0:04:29 > 0:04:31What are you doing?
0:04:31 > 0:04:33SHE LAUGHS
0:04:33 > 0:04:35Look at her go!
0:04:35 > 0:04:39Guys, you know, thanks for your input and that,
0:04:39 > 0:04:44but I really think that Gaia and I can take it from here.
0:04:44 > 0:04:46Fine.
0:04:46 > 0:04:48We know when we're not wanted. Come on, babes. Skink.
0:04:50 > 0:04:54- I think it might be, "something something team."- Nice one.
0:04:54 > 0:04:56DOOR OPENS
0:04:56 > 0:04:58There's some sort of security breach up at the castle.
0:04:58 > 0:05:01Gaia, AJ, you need to get your stuff together.
0:05:01 > 0:05:04My chaperone is waiting outside to take you two back.
0:05:04 > 0:05:06- What's going on?- No idea.
0:05:10 > 0:05:12Whatever it is, MacAJ is not being split up this time.
0:05:12 > 0:05:13Hey!
0:05:15 > 0:05:17Let's go.
0:05:43 > 0:05:46Hey, good to see you. I was getting worried about you guys.
0:05:46 > 0:05:49There's been all sorts of alarms going off,
0:05:49 > 0:05:51- I thought you'd been caught. - We thought we'd been caught too.
0:05:51 > 0:05:53Did you get it?
0:05:57 > 0:05:58Whoa.
0:05:58 > 0:06:01Hey, has Cat turned up?
0:06:01 > 0:06:03If she did I haven't seen her.
0:06:03 > 0:06:04Here, come on.
0:06:09 > 0:06:10Who's that?
0:06:12 > 0:06:13Gaia!
0:06:16 > 0:06:17Are you angry at me?
0:06:17 > 0:06:20For allowing the imposter Cat to come to the summoning
0:06:20 > 0:06:23- and weaken you? - I'm not angry with you...
0:06:23 > 0:06:24but I have been weakened.
0:06:26 > 0:06:28I don't even have the power to unlock this door.
0:06:39 > 0:06:41How did you do that?
0:06:43 > 0:06:46This lens replicates General Winters' iris.
0:06:49 > 0:06:52That's ingenious. You...
0:06:53 > 0:06:56You're going to be my number two in the new world.
0:06:56 > 0:07:01Now, let's get me out of here and into the castle grounds.
0:07:01 > 0:07:04Good. Give it to me.
0:07:05 > 0:07:07Give it to The Origin.
0:07:13 > 0:07:16Luke, where have you been? Look, just find your brother.
0:07:16 > 0:07:18- Stay inside the apartment, please.- Why?
0:07:18 > 0:07:21Is it something to do with the alarms going off earlier?
0:07:21 > 0:07:23Yes, there's been some sort of security breach.
0:07:23 > 0:07:26It's just a contingency operation, but I would like you to stay inside.
0:07:26 > 0:07:28You two, do the same as well, please.
0:07:30 > 0:07:32So, if the alarms are nothing to do with you guys,
0:07:32 > 0:07:35- what are they to do with? - Casey, maybe.
0:07:35 > 0:07:38Mummy and Major Javadi were after him for some reason.
0:07:43 > 0:07:48- Hey, where have you been? We were worried.- You were worried, you mean.
0:07:48 > 0:07:50It's a long story.
0:07:50 > 0:07:53I mean, for goodness' sake, look at her.
0:07:53 > 0:07:56What is the point in giving them all ID cards
0:07:56 > 0:07:58if you don't check them every time?
0:07:58 > 0:07:59And where's my daughter?
0:07:59 > 0:08:01- I don't even know who your daughter is.- It's OK.
0:08:01 > 0:08:04Gaia's back at the cafe. She didn't want to come home yet, so...
0:08:04 > 0:08:07I expected better of you, AJ. Now get back to your quarters.
0:08:07 > 0:08:10- Can I at least say goodbye first? - No. Go.
0:08:10 > 0:08:11Bye.
0:08:11 > 0:08:14Now get this girl back to the village and fetch Gaia, immediately.
0:08:14 > 0:08:17- No, AJ, wait!- Hey. Get her!
0:08:17 > 0:08:18Look, AJ, come back!
0:08:19 > 0:08:23- You can't treat us like this.- Come on.- What are you doing?- Not so fast.
0:08:23 > 0:08:24- Get off her.- AJ!
0:08:25 > 0:08:28This is private property, young lady, and you are trespassing.
0:08:28 > 0:08:30- Not for the first time either. - I was just saying goodbye,
0:08:30 > 0:08:32or is that a crime round here too?
0:08:33 > 0:08:35Get in the truck.
0:08:52 > 0:08:54Maybe it isn't, "Team."
0:08:55 > 0:08:59- How about, "Something, something technology?"- No.
0:08:59 > 0:09:03I think we were onto something with team.
0:09:03 > 0:09:05Maybe there's a clue in here.
0:09:05 > 0:09:08"Collaboration team?"
0:09:08 > 0:09:09- "Combat team?"- It could be combat.
0:09:09 > 0:09:11It is a military base.
0:09:13 > 0:09:14Maybe if you could tell me
0:09:14 > 0:09:17a bit more about what's going on in that lab...
0:09:17 > 0:09:19- I can't.- Right.
0:09:19 > 0:09:22DOOR OPENS
0:09:28 > 0:09:31Looks like it's time for me to go anyway.
0:09:31 > 0:09:34- Can I borrow this?- Sure.
0:09:47 > 0:09:49Gaia!
0:09:49 > 0:09:51If they won't let you out after this,
0:09:51 > 0:09:54promise you'll get a message to me, through my mum or something.
0:09:54 > 0:09:56I promise.
0:09:57 > 0:09:59You take care of yourself, yeah?
0:10:05 > 0:10:09I can't believe Casey locked you in that horrible cell.
0:10:09 > 0:10:13- Why was he in the SZ? Where was he going?- The rocket?
0:10:13 > 0:10:16Is that true about Titan? I mean really true?
0:10:16 > 0:10:18I swear on my life.
0:10:18 > 0:10:22- Insane.- Like Casey.
0:10:22 > 0:10:25If this thing is so important, why wasn't Casey taking it with him?
0:10:25 > 0:10:27Maybe I was wrong and it isn't important.
0:10:27 > 0:10:30What if it was just part of Casey's game?
0:10:30 > 0:10:32A way to control our siblings down there.
0:10:32 > 0:10:36No. It's connected to what's going on in the SZ - I know it is.
0:10:36 > 0:10:39Talking of the SZ, I know what those symbols are.
0:10:40 > 0:10:44They're actually letters. A-C-T - it's an acronym.
0:10:44 > 0:10:50An acronym is a word made up of the initial letters of other words,
0:10:50 > 0:10:53like Scuba - self contained underwater breathing apparatus.
0:10:53 > 0:10:55Get it?
0:10:56 > 0:11:00Anyway, the acronym here is ACT
0:11:00 > 0:11:03and I think it might be "something, something team",
0:11:03 > 0:11:06possibly "combat team."
0:11:06 > 0:11:09- Contingency?- What?
0:11:09 > 0:11:11Contingency team.
0:11:11 > 0:11:15Well, it could be. I mean, your mum used the word earlier.
0:11:15 > 0:11:19Oh, and the stone circle might actually be an alter.
0:11:19 > 0:11:23- Hey, nice one, Gaia.- Thanks.
0:11:23 > 0:11:27Casey had drawings of that circle all over his wall, remember?
0:11:27 > 0:11:29Linked to The Object.
0:11:29 > 0:11:32They worship The Object like a god, right?
0:11:32 > 0:11:35So if this stone circle thing really is an alter, then...
0:11:35 > 0:11:38- We go to the cave. - And we're doing that because?
0:11:38 > 0:11:41- Maybe if we put the object on the alter it'll...
0:11:41 > 0:11:42- Roll off.
0:11:42 > 0:11:44LEXY: Have you got a better idea?
0:11:45 > 0:11:48- Weird things happen around that circle, that's all I'm saying.
0:11:48 > 0:11:49- Come on.
0:11:52 > 0:11:55Your fears about sabotage appear to be unfounded, Lena.
0:11:55 > 0:11:59He wasn't planning sabotage, Adam, he was planning on going it alone.
0:11:59 > 0:12:01Not even Casey's that unhinged.
0:12:01 > 0:12:03Is he?
0:12:03 > 0:12:05There's only one way to find out.
0:12:09 > 0:12:10Alert security immediately.
0:12:17 > 0:12:22It's beautiful. Amber - an ancient symbol of energy and renewal.
0:12:22 > 0:12:26- It's fossilised tree sap, Gaia. - It's still beautiful.
0:12:26 > 0:12:29In ancient times, amber was known as electron.
0:12:29 > 0:12:33- I've always thought it would be quite a nice first name.- Electron Roberts?
0:12:33 > 0:12:35Sounds like a vacuum cleaner.
0:12:35 > 0:12:36Amber.
0:12:36 > 0:12:38OK, we're ready over here.
0:12:52 > 0:12:55- What's happening? - Electron energy.
0:12:58 > 0:12:59Wow!
0:13:05 > 0:13:06What is that?
0:13:06 > 0:13:08It's the Solar System.
0:13:08 > 0:13:11There's the Sun, look. There's Earth.
0:13:15 > 0:13:17What is that?
0:13:20 > 0:13:21Duck!
0:13:23 > 0:13:27- It's an asteroid. A-C-T - "asteroid something team."
0:13:27 > 0:13:31- Asteroid combat team? Asteroid contingency team?
0:13:31 > 0:13:34It's going to hit.
0:13:36 > 0:13:39- A is for apocalypse. - The end of the world.
