0:00:24 > 0:00:26Cat? Cat, what is it?
0:00:26 > 0:00:29I was in here, Noah. With my parents.
0:00:29 > 0:00:30I think. And...
0:00:32 > 0:00:33And Lexy was with us.
0:00:33 > 0:00:34Lexy?
0:00:36 > 0:00:37Where are you going? Cat?
0:00:41 > 0:00:42- Is Luke down there?- Yeah.
0:00:47 > 0:00:48You can't just leave us with that!
0:00:48 > 0:00:51He's fine. Noah might need some help getting him out.
0:01:01 > 0:01:03BANGS ON DOOR
0:01:06 > 0:01:07What?
0:01:08 > 0:01:09Lexy...
0:01:11 > 0:01:13I know this is going to sound strange, but...
0:01:13 > 0:01:14..my parents...
0:01:15 > 0:01:17..they disappeared.
0:01:17 > 0:01:19Here, I think. And...
0:01:20 > 0:01:22..I think I saw you with them.
0:01:22 > 0:01:24How could you have seen me with them?
0:01:24 > 0:01:25I don't even know your parents.
0:01:25 > 0:01:27And I've been in here all evening.
0:01:27 > 0:01:29I don't mean now, Lexy. I mean...
0:01:31 > 0:01:33Please... Just tell me.
0:01:34 > 0:01:36Do you know what happened to them?
0:01:36 > 0:01:38How would I know?
0:01:38 > 0:01:39Tell me!
0:01:40 > 0:01:42I have no idea what you're talking about.
0:01:42 > 0:01:45And get your low-rent low tops out of my doorway!
0:01:47 > 0:01:48Oh...!
0:01:48 > 0:01:51Noah, I can't see.
0:01:51 > 0:01:52That could be a concussion.
0:01:52 > 0:01:55No! It's you, shining your flashlight in my eyes.
0:01:55 > 0:01:58You got a nasty bang to the head. You got to get it checked out.
0:01:58 > 0:01:59I'm fine.
0:02:02 > 0:02:04Whoa...
0:02:04 > 0:02:05There really is a cave!
0:02:05 > 0:02:07Yep. There really is.
0:02:07 > 0:02:09Cat said you might need our help.
0:02:09 > 0:02:12Yes! Thank you. Will someone, please, tell him...
0:02:12 > 0:02:14Ouch! That looks nasty.
0:02:14 > 0:02:15I feel fine.
0:02:15 > 0:02:17Oh...! And what happened to your arms?
0:02:17 > 0:02:20Gaia, it's just pen...
0:02:20 > 0:02:21Why would you do that?
0:02:22 > 0:02:24OK... Group vote.
0:02:24 > 0:02:27Hands up who thinks Luke should get checked out?
0:02:39 > 0:02:41Did you do this?
0:02:41 > 0:02:43- No!- I told you.
0:02:43 > 0:02:47I ate a bad sandwich, passed out, hit my head.
0:02:48 > 0:02:50You three, wait outside, please.
0:02:50 > 0:02:52What happened?
0:02:52 > 0:02:54A violent sandwich, apparently.
0:02:56 > 0:02:58Well, you'll live.
0:02:58 > 0:02:59But you take it easy.
0:02:59 > 0:03:02I don't want you on your own at all for the next 24 hours.
0:03:02 > 0:03:04You got it?
0:03:04 > 0:03:07Yes, that's fine. Noah can keep an eye on him. Can't you?
0:03:07 > 0:03:10If he's sick, woozy, slurry,
0:03:10 > 0:03:11you come and get me straightaway.
0:03:11 > 0:03:14- I don't need a baby-sitter. - I mean it, Luke.
0:03:14 > 0:03:16Or I'll watch over you myself.
0:03:17 > 0:03:18It's fine. I get it.
0:03:20 > 0:03:21Stephanie...
0:03:22 > 0:03:25Where were you when this happened?
0:03:25 > 0:03:26What, me?
0:03:26 > 0:03:30He's not a kid any more. I can't keep watch over him 24-7, Duncan.
0:03:30 > 0:03:31So it would seem.
0:03:31 > 0:03:34How long's that been Noah's job?
0:03:34 > 0:03:37Criticise my parenting when you've actually done some, OK?
0:03:37 > 0:03:40Well, I would. But I wasn't given the chance, was I?
0:03:40 > 0:03:41Oh, get over yourself!
0:03:44 > 0:03:47- I'll be out there. - No, there's nothing wrong with me.
0:03:47 > 0:03:49Hey, where did you rush off to?
0:03:49 > 0:03:51- I went to see Lexy.- And?
0:03:52 > 0:03:54Just leave it, Noah, yeah?
0:04:00 > 0:04:02Mummy, last night, I had a visit from Caitlin.
0:04:02 > 0:04:03Ssh...
0:04:03 > 0:04:06- But...- What have I said about speaking to me when I'm busy?
0:04:06 > 0:04:07But I've looked in your diary
0:04:07 > 0:04:10and I can't find any other time to speak to you.
0:04:10 > 0:04:12Then, don't.
0:04:22 > 0:04:24Are you OK?
0:04:27 > 0:04:30Get these repugnant things out of my room!
0:04:30 > 0:04:31- Sorry.- Don't!
0:04:38 > 0:04:40She's not a morning person.
0:04:45 > 0:04:47Where's Cat?
0:04:47 > 0:04:49She's not feeling too well, apparently.
0:04:49 > 0:04:50You could say. When I saw her,
0:04:50 > 0:04:54she was screaming some sort of lunacy about her parents.
0:04:54 > 0:04:57- And what did you say to her? What do you know about them?- Nothing.
0:04:57 > 0:05:01Oh, come on. You're practically your mum with the wrinkles peeled off.
0:05:01 > 0:05:04You expect me to believe you don't know what's going on round here?
0:05:04 > 0:05:06Er, yes. Because I don't.
0:05:07 > 0:05:09Then, more fool you.
0:05:15 > 0:05:16What are you looking at?
0:05:19 > 0:05:21No wonder she's like she is.
0:05:21 > 0:05:23Lena won't even let her speak!
0:05:23 > 0:05:25What?!
0:05:25 > 0:05:27- That's horrible!- Yuh-huh.
0:05:27 > 0:05:31OK, today we're going to look at cultivating plant life
0:05:31 > 0:05:34in difficult terrain.
0:05:34 > 0:05:36Lexy?
0:05:36 > 0:05:38How do you kill plants?
0:05:45 > 0:05:48- Where are you going?- To the cave.
0:05:48 > 0:05:51What? And you think it's a good idea to drag him in there?
0:05:51 > 0:05:54Well, we won't be dragging him. That'd be a bit weird.
0:05:54 > 0:05:55And messy.
0:05:55 > 0:05:58Maybe we should, you know, wait until you've got the all clear.
0:05:58 > 0:06:01Oh, we could go to the cafe, shoot some pool?
0:06:01 > 0:06:03Oh, and AJ's girlfriend's always good for a laugh.
0:06:03 > 0:06:05- She's not my girlfriend!- I'm in.
0:06:05 > 0:06:08Wait. I need to get my purse. See you guys there.
0:06:10 > 0:06:11Fine...
0:06:12 > 0:06:15But if you're going to fuss over someone, try Cat.
0:06:15 > 0:06:17She seems more affected by that cave than me.
0:06:24 > 0:06:25Ah...
0:06:25 > 0:06:27Misting my plants!
0:06:27 > 0:06:28You're so sweet!
0:06:30 > 0:06:32- Weedkiller?! What are you doing? - Plants belong outside.
0:06:32 > 0:06:35No! Please, Lexy! Not Lucy! Please...
0:06:35 > 0:06:38What is all this horrendous girlish shrieking?
0:06:38 > 0:06:41- She's taking up all my space! - She's trying to kill my plants!
0:06:41 > 0:06:43Lexy, put down the weedkiller.
0:06:43 > 0:06:46Gaia, take them back to your quarters.
0:06:46 > 0:06:47But they'll get lonely!
0:06:47 > 0:06:49Do not question me!
0:06:50 > 0:06:52You may keep one plant. The rest go.
0:06:52 > 0:06:54Now!
0:06:57 > 0:06:59I know what you're doing.
0:07:00 > 0:07:03You're taking your anger at your mum out on me.
0:07:04 > 0:07:07No. I'm taking my anger at you out on you.
0:07:08 > 0:07:11The way things are here, with you and your mum,
0:07:11 > 0:07:14that's not everyone's version of normal. You know that, right?
0:07:15 > 0:07:18I mean, me and my dad, we talk all the time.
0:07:18 > 0:07:21We don't keep anything from each other.
0:07:22 > 0:07:23Just saying.
0:07:26 > 0:07:27Go away.
0:07:29 > 0:07:30Go away!
0:07:36 > 0:07:37Cat?
0:07:39 > 0:07:42Cat, I'm not going anywhere until you speak to me.
0:07:53 > 0:07:57I managed to copy some of them down, but the rest got smudged.
0:07:57 > 0:07:58What do you think they mean?
0:07:58 > 0:08:00Don't know.
0:08:00 > 0:08:04But whoever drew them clearly didn't have any paper.
0:08:04 > 0:08:07I mean, why else would they draw on a cave wall?
0:08:07 > 0:08:09Er, maybe to record historical events?
0:08:09 > 0:08:11No, you'd just use a computer for that.
0:08:11 > 0:08:12Oh...
0:08:12 > 0:08:15You found the cave? When?
0:08:15 > 0:08:17You never tell me anything!
0:08:17 > 0:08:20- I haven't seen you! - Yeah. He hasn't seen you.
0:08:21 > 0:08:23- You never tell her anything!- Aw!
0:08:25 > 0:08:27Wait... I've seen those before.
0:08:27 > 0:08:29- Where? - On this documentary thing.
0:08:29 > 0:08:32These explorers found a cave full of these symbols
0:08:32 > 0:08:35and they were like, "What are these?"
0:08:35 > 0:08:37Turns out the cave was a demon portal.
0:08:39 > 0:08:43But it's true! I saw one about a mermaid that'd been washed up, too.
0:08:43 > 0:08:46OK. Well, thank you, Mackenzie, er...
0:08:47 > 0:08:48..we'll keep it in mind.
0:08:49 > 0:08:52Come on, Skink. They've just got imagination deficit disorder.
0:08:59 > 0:09:01Where did you find those?
0:09:01 > 0:09:03We found the cave. Why?
0:09:03 > 0:09:04I've seen them before.
0:09:04 > 0:09:05Don't say it.
0:09:05 > 0:09:08A documentary, a creepy cave, demon portal...
0:09:08 > 0:09:10No. I've seen them for real.
0:09:18 > 0:09:19Mummy...
0:09:19 > 0:09:21I'm busy.
0:09:21 > 0:09:24Caitlin told me she thinks her parents disappeared here
0:09:24 > 0:09:25and I was with them.
0:09:25 > 0:09:27What did she mean?
0:09:29 > 0:09:31Don't be so gullible, Lexy.
0:09:32 > 0:09:35Caitlin's obviously just making a joke at your expense.
0:09:35 > 0:09:37Of course she is.
0:09:37 > 0:09:39I knew there was a reason I didn't like her.
0:09:39 > 0:09:40I have work to do.
0:10:00 > 0:10:04Hey... I was starting to think you'd made another run for it.
0:10:05 > 0:10:08You think the military did that after my parents disappeared?
0:10:08 > 0:10:09To stop anyone else getting in?
0:10:11 > 0:10:12I don't know.
0:10:15 > 0:10:17I thought that finding the cave
0:10:17 > 0:10:20would give me the answers I was looking for.
0:10:23 > 0:10:24Come on.
0:10:29 > 0:10:33So, why were you digging around in that cave in the first place?
0:10:33 > 0:10:36Got anything to do with what's going on in that freaky castle?
0:10:36 > 0:10:39No, we're looking for some dead teenagers' bones.
0:10:39 > 0:10:41We think they're haunting the place.
0:10:41 > 0:10:44So, we want to give them a proper burial, finally lay them to rest.
0:10:44 > 0:10:45Why didn't you just say?
0:10:45 > 0:10:48Me and Skink have literally got hundreds of years
0:10:48 > 0:10:49of ghost-hunting under our belts.
0:10:49 > 0:10:51Hundreds.
0:10:51 > 0:10:52Literally.
0:10:52 > 0:10:53If you're looking for bones,
0:10:53 > 0:10:57our limited edition divining rods are a scientifically proven success.
0:10:57 > 0:10:59Last year, we found a dinosaur bone.
0:10:59 > 0:11:02Well, my granny said it was actually a cow's pelvis.
0:11:02 > 0:11:03Shut up!
0:11:05 > 0:11:06Do you want them or not?
0:11:06 > 0:11:07Sure.
0:11:07 > 0:11:10Thanks, Mac. I think these will come in very handy.
0:11:14 > 0:11:15He called me Mac...
0:11:17 > 0:11:18I hate that.
0:11:27 > 0:11:28Where did you find this?
0:11:28 > 0:11:30It was in Lieutenant Winters' jacket.
0:11:30 > 0:11:32Casey's?
0:11:32 > 0:11:35Why would Casey have drawings of the cave symbols?
0:11:35 > 0:11:37You think he knows something?
0:11:37 > 0:11:39Only one way to find out.
0:11:39 > 0:11:40Can I have this?
0:11:40 > 0:11:42Sure.
0:11:58 > 0:11:59BEEPING
0:11:59 > 0:12:00Yes.
0:12:16 > 0:12:18The materials have arrived.
0:12:26 > 0:12:28I still think it's a wasted expense.
0:12:30 > 0:12:32But I've told them to begin construction tomorrow.
0:13:01 > 0:13:02Hey...
0:13:03 > 0:13:05Sorry for laying into you earlier.
0:13:05 > 0:13:09But if you can remember anything about Cat's parents disappearing,
0:13:09 > 0:13:10she really needs to know.
0:13:10 > 0:13:14Oh, so this isn't about me. It's about Caitlin.
0:13:14 > 0:13:16Of course it is.
0:13:16 > 0:13:18I don't know anything.
0:13:19 > 0:13:21I take it back. You're just like the adults.
0:13:21 > 0:13:23Open your eyes, Lexy, you're being played.
0:13:23 > 0:13:25Really?
0:13:25 > 0:13:28Because, from where I'm standing, I'd say that you're being played.
0:13:28 > 0:13:30What's that supposed to mean?
0:13:32 > 0:13:33Birth certificates.
0:13:35 > 0:13:37Apparently, all of us were born here.
0:13:38 > 0:13:40Mine's missing. Where is it?
0:13:40 > 0:13:42Good question.
0:13:42 > 0:13:44Maybe you're going to disappear, too.
