0:00:15 > 0:00:17That's Whatshisname Winters from the castle.
0:00:17 > 0:00:19I thought she said she was getting a taxi into town?
0:00:19 > 0:00:21Maybe he's kidnapped her.
0:00:21 > 0:00:22Follow that car!
0:00:27 > 0:00:28What now?
0:00:40 > 0:00:41Why have you stopped here?
0:00:42 > 0:00:46I understand what it's like to be fed a cover story which later
0:00:46 > 0:00:48unravels into a pack of lies.
0:00:48 > 0:00:51Just take me back to the castle and get it over with.
0:00:51 > 0:00:55I'm sure Lena's waiting, ready to dole out some punishment or other.
0:00:55 > 0:00:57Is that what you think?
0:00:57 > 0:00:59That I'm Lena's lapdog?
0:00:59 > 0:01:01I detest that woman.
0:01:05 > 0:01:10I was away at boarding school when I found out that my father had died.
0:01:12 > 0:01:14Heart attack.
0:01:14 > 0:01:16Why are you telling me this?
0:01:16 > 0:01:18Several years later,
0:01:18 > 0:01:21I discovered that my father hadn't died after all.
0:01:21 > 0:01:22Lena had lied to me.
0:01:24 > 0:01:27So what did happen to him?
0:01:27 > 0:01:29Disappeared.
0:01:31 > 0:01:33Like my parents?
0:01:33 > 0:01:35Yes.
0:01:35 > 0:01:39You see, Cat, we have more in common than you might think.
0:01:39 > 0:01:42- I'm trying to help you. - By keeping me prisoner?
0:01:46 > 0:01:49Look, if you really want to go...
0:01:49 > 0:01:50Just go.
0:02:00 > 0:02:02Just tell me one thing.
0:02:04 > 0:02:07What are you hoping to find in town that you can't find here?
0:02:07 > 0:02:08Why I was brought here
0:02:08 > 0:02:11and who's been looking out for me all these years.
0:02:13 > 0:02:15Well, that's easy.
0:02:15 > 0:02:18It was me.
0:02:18 > 0:02:19What?
0:02:19 > 0:02:22At least, I'm the person who's been paying money into your account
0:02:22 > 0:02:25- every month.- You're lying! You would have told me when I first got here.
0:02:25 > 0:02:29I couldn't, I was acting under orders - Lena's orders. I am sorry.
0:02:30 > 0:02:33Come back to the castle with me, I'll prove it to you.
0:02:33 > 0:02:36And I promise, I'll answer any other questions that you might have.
0:02:38 > 0:02:40I'm on your side, Cat.
0:02:43 > 0:02:46But if you still want to go into town, that's fine.
0:02:46 > 0:02:48I'll drive you there myself.
0:02:49 > 0:02:51We need to phone the police.
0:02:51 > 0:02:52No, they won't take us seriously.
0:02:52 > 0:02:55- Remember the yeti footprint phone call?- Oh, and the UFO phone call.
0:02:55 > 0:02:57Exactly! We weren't the only ones
0:02:57 > 0:03:00- to see strange, flying aircraft that night.- But would they listen?- No.
0:03:00 > 0:03:02Too busy arresting drunks and giving out parking tickets to
0:03:02 > 0:03:05worry about a little thing like an alien invasion.
0:03:05 > 0:03:07Look who I bumped into in the village.
0:03:07 > 0:03:10- Your mum said I left something behind?- Yeah, be with you in a sec.
0:03:10 > 0:03:11There's your change...
0:03:11 > 0:03:14So will you have a think about me helping out in the kitchen, Moira?
0:03:14 > 0:03:19Oh, I don't think it would be really very practical. I'm sorry, Gaia.
0:03:19 > 0:03:22Although I could possibly do with an extra pair of hands cleaning
0:03:22 > 0:03:26- the tables?- I'll do it!- OK. I'm warning you, I don't pay very well.
0:03:26 > 0:03:29- Ask Gregor.- Mum!- What?
0:03:31 > 0:03:33So, what did I leave behind, exactly?
0:03:33 > 0:03:34She came back.
0:03:37 > 0:03:41- I looked everywhere for you! - She's actually pretty friendly.
0:03:43 > 0:03:46- We need to find out where she lives.- Aye.
0:03:46 > 0:03:48She can stay for now, but mum won't let her inside,
0:03:48 > 0:03:52so it'll have to be temporary. I'll save her some snacks.
0:03:52 > 0:03:55Hey, you! If that Cat girl doesn't come back to the
0:03:55 > 0:03:58castle tonight, come and talk to us - we're gathering intel.
0:03:59 > 0:04:02Ignore them, I always do.
0:04:03 > 0:04:05So, here's the amount going out of my account every month
0:04:05 > 0:04:09and these are the payee details here.
0:04:09 > 0:04:11That is your account, right?
0:04:11 > 0:04:12I don't understand.
0:04:12 > 0:04:14After your parents went missing,
0:04:14 > 0:04:17my father took it upon himself to set up a trust fund for you.
0:04:17 > 0:04:20Six months later, he "died".
0:04:22 > 0:04:23There was a will.
0:04:23 > 0:04:27Unfortunately for you, I inherited father's estate.
0:04:27 > 0:04:30- You're the owner of World's End Castle?- Yeah.
0:04:30 > 0:04:33I said I wanted the fund to remain in place.
0:04:33 > 0:04:35Lena was dead against it, but there wasn't much she could do.
0:04:35 > 0:04:38She did, however, insist that you were sent away to school
0:04:38 > 0:04:42and all links to World's End severed.
0:04:42 > 0:04:44And you agreed to that?
0:04:44 > 0:04:46I was very young, Cat - I trusted the adults.
0:04:46 > 0:04:49But now, like you, I'm beginning to realise they're all liars!
0:04:49 > 0:04:52And that something very sinister's going on.
0:04:52 > 0:04:54And what about my parents?
0:04:54 > 0:04:56What do you know about them?
0:04:56 > 0:04:59- Let's continue this later, somewhere private.- No, please, now!
0:04:59 > 0:05:00Oh, there you are, Casey.
0:05:00 > 0:05:03We need to have a chat about those stats you gave me earlier.
0:05:03 > 0:05:04If we must.
0:05:06 > 0:05:08Decided not to go then?
0:05:08 > 0:05:10Noah and Luke mentioned something.
0:05:10 > 0:05:12Didn't have much choice in the end.
0:05:14 > 0:05:18- Any sightings of either the kidnapper or the girl?- Nothing.
0:05:18 > 0:05:19What's Private Combover doing?
0:05:19 > 0:05:22Ugh, mining for bogeys?
0:05:23 > 0:05:25It's boring being a detective on a stakeout.
0:05:25 > 0:05:28We need doughnuts, they have doughnuts in all the movies.
0:05:28 > 0:05:31Why is this sand so lumpy? It's hurting my bum.
0:05:31 > 0:05:35- I think there's a rock... - Just move, why don't you?!
0:05:35 > 0:05:37Skink, I've found something.
0:05:42 > 0:05:44And this is big, right?
0:05:44 > 0:05:48Luke and Cat think our wacko parents are training up guerrilla soldiers!
0:05:48 > 0:05:50- Is that even possible? - Of course it's possible!
0:05:50 > 0:05:52I know they're intelligent and everything,
0:05:52 > 0:05:55but how do they get them to fight?
0:05:55 > 0:05:57- Who?- The gorillas.- Ha!
0:05:57 > 0:06:00Gorillas are definitely more intelligent than you, you bozo.
0:06:00 > 0:06:01Yeah?
0:06:01 > 0:06:04And with nicer personalities than you, you witch.
0:06:04 > 0:06:06Guys, knock it off.
0:06:06 > 0:06:07I wonder how Cat's getting on.
0:06:07 > 0:06:09Funny you should mention that. I was in the mess earlier
0:06:09 > 0:06:12- and I saw...- Cat!
0:06:12 > 0:06:14Hey, you changed your mind.
0:06:14 > 0:06:17No. Someone ratted me out to Casey...
0:06:17 > 0:06:20and I think we all know who that was, don't we, Noah?
0:06:20 > 0:06:22I didn't say anything to anybody.
0:06:22 > 0:06:25It's true, he's been with me the whole time.
0:06:25 > 0:06:27Well, someone told him.
0:06:27 > 0:06:29It was me.
0:06:29 > 0:06:32- You.- Why am I not surprised?
0:06:32 > 0:06:34It was an accident.
0:06:34 > 0:06:36It just sort of slipped out.
0:06:36 > 0:06:38- Sorry.- Whoa-ho!
0:06:38 > 0:06:40Lexy just apologised!
0:06:40 > 0:06:42Falls on the floor in amazement!
0:06:44 > 0:06:46How did he manage to talk you out of going?
0:06:46 > 0:06:47Or did he make you come back?
0:06:47 > 0:06:49- No, he didn't make me.- So...
0:06:53 > 0:06:56By the way, I think you owe me an apology!
0:06:56 > 0:06:59- Can we put one up in here too? - Sure.
0:06:59 > 0:07:01Hooray, I am off.
0:07:01 > 0:07:04Gregor, could you lock up for me, please?
0:07:04 > 0:07:05Oh, hello, Gaia. You still here?
0:07:05 > 0:07:09I know, I should get back before they send out the search party.
0:07:09 > 0:07:12- Look what we found! - We found it buried in the dunes.
0:07:12 > 0:07:15- Do you know what it is?- Yeah, some kind of alien pod or egg.
0:07:15 > 0:07:18- We need to get open, come on, Skink! - Hang on, we're closing.
0:07:18 > 0:07:21I saw this film once when music was, like, the universal language,
0:07:21 > 0:07:24which finally got through to the barbaric alien life form.
0:07:24 > 0:07:26TUNELESS HIGH NOTES
0:07:26 > 0:07:28That's painful.
0:07:28 > 0:07:30The higher the frequency the better.
0:07:30 > 0:07:32FURTHER TUNELESS NOTES
0:07:34 > 0:07:35I really need to go.
0:07:35 > 0:07:37THEY CONTINUE SINGING
0:07:40 > 0:07:41They're nuts.
0:07:41 > 0:07:43It's actually a Pictish ball.
0:07:43 > 0:07:45There are drawings of them in the cave.
0:07:45 > 0:07:47I'll see you, Gregor.
0:07:54 > 0:07:58- I'll get the new stats back to you first thing.- Make sure you do.
0:08:01 > 0:08:03Casey!
0:08:03 > 0:08:06- Cat, what are you doing here? - Looking for you.
0:08:06 > 0:08:07I wanted to finish our talk.
0:08:09 > 0:08:12Well, come on then, before the Ice Queen catches us.
0:08:19 > 0:08:20You OK?
0:08:20 > 0:08:21It was you.
0:08:22 > 0:08:24You were the one that found me in the cave,
0:08:24 > 0:08:26right after my parents disappeared.
0:08:26 > 0:08:28You remember that?
0:08:28 > 0:08:30You helped me.
0:08:30 > 0:08:32Yeah.
0:08:32 > 0:08:35Just like I'm going to help you now.
0:08:35 > 0:08:36Come on.
0:08:41 > 0:08:45- So, what happened to them? You can tell me the truth.- The truth?
0:08:46 > 0:08:48I don't know.
0:08:48 > 0:08:49- But you have to.- Nobody knows.
0:08:49 > 0:08:53Your mum and dad were last seen doing some research on those old
0:08:53 > 0:08:56- paintings in the cave. You were with them at the time.- And Lexy?
0:08:56 > 0:08:59Not that I'm aware of. What makes you ask that?
0:08:59 > 0:09:00A memory.
0:09:00 > 0:09:02I used to hang out in that cave.
0:09:02 > 0:09:07I came in and found you there, crying for your mum and dad...
0:09:08 > 0:09:09..but they'd gone.
0:09:09 > 0:09:11It's that cave.
0:09:11 > 0:09:14Two children disappeared there during the '60s, did you hear about that?
0:09:14 > 0:09:16I've heard the rumours, yes.
0:09:16 > 0:09:19Look, Cat, I understand how important all this stuff is,
0:09:19 > 0:09:22and I promise I will try and help you, but it's what's happening
0:09:22 > 0:09:25at the castle now that concerns me more.
0:09:25 > 0:09:26The chemical weapons?
0:09:26 > 0:09:31- Oh, so Noah's told you then! - Only what he saw.
0:09:31 > 0:09:33So, what happens now?
0:09:33 > 0:09:37What happens now is that we work together and we find out the truth.
0:09:37 > 0:09:40Leave me to deal with Lena and the others. Give me some space,
0:09:40 > 0:09:44I'll find out what's going on. Can you be patient and do that?
0:09:44 > 0:09:46Good.
0:09:46 > 0:09:49But what about me? What can I do?
0:09:49 > 0:09:52You, keep your ears and your eyes open,
0:09:52 > 0:09:54and let me know if you find out anything, OK?
0:10:01 > 0:10:02- Oh, Cat!- Hi.
0:10:03 > 0:10:06- You OK? - Little bit in shock, to be honest.
0:10:08 > 0:10:11Casey's the one that's been looking out for me, Luke.
0:10:11 > 0:10:13- The one paying into my account. - What?!
0:10:13 > 0:10:16He's under orders not to tell me, so we have to keep it quiet, but...
0:10:16 > 0:10:18He knew my parents.
0:10:18 > 0:10:21I actually remember him helping me after they disappeared.
0:10:21 > 0:10:23And I think Noah's right, I think he's on our side.
0:10:23 > 0:10:25Bit of a coincidence, isn't it?
0:10:25 > 0:10:27The day you decide to go to the authorities,
0:10:27 > 0:10:29Casey gives you all this info.
0:10:29 > 0:10:32Well, he's not lying about the money, I saw the proof.
0:10:33 > 0:10:35If he is being genuine, then...
0:10:37 > 0:10:39Does he know about the twins?
0:10:39 > 0:10:43I don't think so. He didn't say. Then again, I didn't either.
0:10:43 > 0:10:46- Do you think I should have? - No, uh-uh.
0:10:46 > 0:10:47But how can we find out the truth
0:10:47 > 0:10:49if we don't even tell each other everything?
0:10:49 > 0:10:53I think you should wait, play this out with Casey first...just in case.
0:10:54 > 0:10:58When did you become so cynical? I thought that was my job.
0:10:59 > 0:11:01There is one thing I can do though,
0:11:01 > 0:11:04- while Casey's investigating Lena and co.- What's that?
0:11:05 > 0:11:07Talk to my sister again.
0:11:07 > 0:11:09So, coming?
0:11:09 > 0:11:13What, now? I don't know.
0:11:13 > 0:11:16- I mean, shouldn't we talk to the others first?- Oh, come on.
0:11:16 > 0:11:20I know how desperate you are to see the "SZ" for yourself.
0:11:22 > 0:11:23OK, follow me.
0:11:25 > 0:11:26Wow!
0:11:28 > 0:11:30Wait - don't we need Lexy to open the doors for us?
0:11:30 > 0:11:32Not where we're going.
0:11:35 > 0:11:38What do they want? Get rid of them!
0:11:44 > 0:11:46DOOR LOCK BEEPS
0:11:49 > 0:11:50Come on.
0:11:52 > 0:11:54- DOOR LOCK BEEPS - Get in.
0:11:58 > 0:12:01Why do you keep doing this? Coming here, putting us at risk?
0:12:01 > 0:12:04We're just looking to get some answers, the same as you.
0:12:04 > 0:12:07- Gaia says you're here to replace us on the mission.- What mission?
0:12:08 > 0:12:10Please, you can trust us - what mission?
0:12:10 > 0:12:13Is something to do with chemical weapons?
0:12:13 > 0:12:15- When is it happening?- Soon.
0:12:18 > 0:12:20Here.
0:12:20 > 0:12:21I want you to have this.
0:12:21 > 0:12:23Why are you giving me your things?
0:12:23 > 0:12:25Because you're my sister.
0:12:31 > 0:12:34You have to let me help you, Caitlin.
0:12:34 > 0:12:37Please, tell me about this mission.
0:12:41 > 0:12:45Gaia says it's very different in your world.
0:12:45 > 0:12:47It is, yes.
0:12:47 > 0:12:50Very different.
0:12:50 > 0:12:53- Maybe you'd like to go and see for yourself?- Cat!
0:12:53 > 0:12:58Before it's too late and you go on the mission?
0:12:58 > 0:12:59What are you saying?
0:12:59 > 0:13:00She doesn't know what she's saying.
0:13:00 > 0:13:02Cat, a word.
0:13:07 > 0:13:11- What are you playing at?! - I'm staying down here, Luke.- No!- Yes!
0:13:11 > 0:13:13I have to find out about this mission -
0:13:13 > 0:13:15the best way to do that is for me to be down here.
0:13:15 > 0:13:17Now come and help me persuade her.
0:13:17 > 0:13:19Cat, no!
0:13:26 > 0:13:30Oh, Luke finally persuaded you to come and apologise then?
0:13:30 > 0:13:33- Are you Luke number two?- What?
0:13:33 > 0:13:35Noah, I tried to stop her, really, I did,
0:13:35 > 0:13:38but you know what Cat's like when she makes a mind up about something.
0:13:38 > 0:13:41No way - you idiot! What have you done?!
0:13:45 > 0:13:47Has the impostor gone?
0:13:47 > 0:13:48Not quite.
