Uncle Charlie thought the lost caves of Gaia were in the East Jungle. But if I'm

right, it's up ahead.

What is that noise?

The Spangled Jongo. They're the loudest birds on the island.

Even louder than lilacs.

Hey, cool rock.

Coarsely vesicular, pyroclastic with a basaltic composition.

I like it.

I think this is it.

Uncle Charlie could never find the caves.

But we have.

The no longer lost caves of Gaea.

What if the caves were lost for a reason?

Maybe there are animals in there. Like cave -dwelling rat snake.

Wait for me!

Actually, don't.

Gee, okay, wait!

Wow, this is crazy.

Amazing. No way.

Brilliant.

I'm standing in the last caves of Gaia, and guess what's here?

Glowworms. I know what you're thinking.

What kind of island mysteriousness is this? Right?

Actually, it's a chemical reaction between luciferin, luciferase, adenosine

triphosphate, and oxygen. In other words, these beautiful creatures were

this way.

Do you feel that?

Uh, what just happened?

The glowworms just became no glowworms. They probably just ran out of battery.

Oh, now how will we find Alice's cave -dwelling rat snakes?

Oh, no. Alice,

stay still!

Hit your head.

Ow!

Anyway, if you feel my vibe, make sure you hit subscribe.

I knew it was a bad idea to go into a cave without a helmet or an airbag.

body armour.

You'll live.

What happened to the rock?

According to Sunny, It died the day they invented disco.

Listen.

The birds, they're silent.

Is it normal for glowworms to just switch off?

It happens, but not suddenly.

But they did stop suddenly, so it has to at least be possible.

Science says no.

Let's go back to the Bermuda Queen. I'll catch you guys later. I've got to edit

this blog, and me, you promised to help.

You're not going to put in that clip of me falling over, right?

Right?

Would we do that?

Right?

What? Where is the Bermuda Queen?

Maybe it's a mirage?

Maybe someone stole it?

How could something that big be removed without leaving any trace?

It was the only proof that I had that Uncle Charlie didn't go missing in a

crash.

And now it's gone.

Hi, Lila.

You need to come home.

I'm kind of in the middle of something. Trust us. You need to come home right

now.

How was it? It was not through the flight yet. She practically flew

She's a dream on days like today.

Uncle Charlie!

Hey, kiddo.

It's you.

Really, you?

Yeah, who else would it be?

What happened to your trip to the mainland, kids?

We... We came back early.

Is it really him?

I... Hi, Nori.

Ella.

You know me?

Of course, you're part of the gang.

going on?

Wow, that is quite a welcome.

What's with the 20 questions?

Where have you been?

Aerial survey of the East Coast, you knew that. I got you something.

For your collection.

My collection?

Cool.

Why are you all acting like this is just a regular day?

This is amazing!

Uncle Charlie is back!

You're delirious. Have you got a temperature?

Everything okay, kiddo?

Lola and Misha were weird earlier too.

Where are they now?

In your bedroom.

Can you excuse us for a minute?

I didn't know what to do, so we ran in here and waited.

This is crazy.

What's going on? I don't know, but from what I gather, we're sharing a room now.

And I really like what we've done to the plays.

And where did they come from?

That's not all. Look at this.

That's us.

With him.

And your cross -country award from, like, the other week.

Maybe this is some kind of prank.

We need to check the hidden cameras.

Mum wouldn't do that to me. Not about Uncle Charlie. Besides, we already

checked. Maybe he's a body double. You know, someone who looks like him but

isn't. It's him.

A little older, but definitely him.

His journal's gone.

Hey, kiddo.

Missed you back early.

Why don't we bring forward your maiden voyage on the Bermuda Queen?

Fly up the coast.

Flying?

In the Bermuda Queen?

Um, sure.

Taylor, do you think this is a good idea?

Uncle Charlie's back, and he wants me to fly with him. In a plane that went

missing. It might not be safe.

No offence to you, Uncle.

But the Bermuda Queen doesn't have the best track record when it comes to not

vanishing with people inside.

I can't not go with him.

Fine. I'm coming along, though, just in case something happens up there. And

we'll stay here in case something happens up there.

You need to get some more fruit.

I bought all this this morning.

And I just watered this.

Hey. Uncle Charlie, is it okay if Nori comes with us?

Of course.

There's no backseat flying.

Will you be passing over the northern reef, Charlie?

We can do. Why?

I just got an urgent report that the coral there is bleaching. Could you

it out? Yeah, we'll do a flyover. Radio back what we see.

Enjoy yourself, Taylor.

You've waited a long time for this day.

You have no idea.

You really don't.

Bye. Bye, guys.

There she is, kiddo.

Now we know where the plane went.

So this is real?

Really real?

Believe it.

You never forget the first time you take the controls.

You want me to fly it? You've been doing simulations long enough. I'll be right

by your side.

What's going on with you two?

It's been a strange morning.

It's about to get a whole lot better.

Get ready for takeoff.

Did you say I could take off?

I think so.

We've done weird before, but this is next level.

Only the three of you here today.

Yeah, Taylor and Nori are with Uncle Charlie.

Lucky them.

He's a dying breed, that man.

Did you see that?

She didn't react at all to Taylor being with Uncle Charlie. So we're the only

ones who think Uncle Charlie was ever missing.

But how can that be?

He has been missing.

Hasn't he?

Maybe we're experiencing a shift in reality.

A multiverse. Same time, just different events.

But I like this universe.

Uncle Charlie's back. I'm sharing a room with Taylor.

But what stops us from shifting realities again?

To one where there is no cake.

Or insects are our overlords.

Or both!

We need to work this out. Now!

You know you can't fly this, right?

I know none of this makes sense, but I don't want to let him down.

He promised me this years ago. What if it's my only chance?

I mean, what if he disappears just as suddenly as he reappeared? And what if

disappear with him? That won't happen.

It might be out of your control.

Safety check complete.

We're all set.

Wait, first, where are the parachutes?

You can do the honours.

You want me to take off? Well, no. That would be crazy.

Yeah, that would be the craziest thing to happen today.

But you can start the engine.

Once we're cruising, she's all yours.

This is amazing!

Alright kiddo, place your hands on the controls.

Nice and steady.

I'm flying!

In the Bermuda Queen, in the air!

Now remember to keep watching the altitude.

BQ62351, copy.

BQ62351 here, go ahead.

We need you to do a flyover of Cape Duncan Archipelago and update the

survey.

Copy that, we'll head there now.

Erosion survey at Cape Duncan Archipelago?

Everything alright?

I could do with a break.

I might stretch my legs.

Exactly what he was doing when he disappeared.

Are you sure?

Yes. What are you going to do?

I don't know.

Taylor! He doesn't like you. What's going on?

I can't go to Cape Duncan Archipelago.

And neither can you.

You flew out there to do that same survey five years ago.

And you never came back.

Once we found the Bermuda Queen, I knew you were still out there somewhere.

So we kept it a secret until we could work out what happened to you.

Until this morning.

I know all this sounds crazy and hard to believe. Are you kidding?

This is me.

I've gone with mermaids, spoken to animals, been chased by shadows. There's

such thing as crazy or hard to believe.

I know, right?

I'm good with finding those lost caves.

I could never do it.

Wait, so we can skip the survey of Cape Duncan Archipelago?

Normally I'm up for anything, but I might pass and go missing for five

Can we still check the reef for mum?

Good call.

Just about there.

Well, what's happening?

Turbulence. Tighten your seatbelt.

Can't you traffic control? This is the Bermuda Queen.

We've encountered some bad air. We're going to try and climb out of it.

So there's the Mandela effect where a bunch of people have a clear memory of

something that never actually happened.

But we were there when it was happening.

So it's not a dream, not a delusion, not a false memory. What if Uncle Charlie's

disappearance isn't the only thing that never happened?

Maybe the Bermuda Queen never happened.

You're right.

Maybe it never existed in the first place.

Maybe we never existed in the first place.

Oh, no. What if we're just figments of someone else's imagination?

Is this chair really a chair? If the birds don't sing, are they really there?

Do something. We're losing him.

Was that really

necessary? We need you to think, not panic.

Clear skies.

You two hanging in there?

Let's have a look at that reef.

Completely white.

It wasn't like that last time I flew over here.

Well, what does that mean?

That it's either dying or already dead.

So, what do we do?

We find out what's causing it.

You do get so fearless.

The dead section looks like it's a path.

Let's follow it back towards the island.

You got it, kiddo?

Here we go again. Hold on.

What happened to that plant? All the grass outside is dead too.

I have no idea. Yesterday it was thriving and then all of a sudden this.

I mean, I'm no great gardener, but this is nuts.

What happened to him?

He's fine. Nothing to see here.

We need to get out of these clouds.

Drawing.

Tyler, I need your help. There's no parachute time, is there? Grab onto the

controls.

What do I do now?

I need you to help me keep her steady, hard as you can.

We need to keep level through this.

That was nuts.

Is that normal?

No. That must have been a freak Rock Island weather event.

Forecast was clear.

It's not just the reef that's sick. The jungle looks like it's dying too.

But why?

I should get you two on the ground.

After we find out what's going on.

You're the boss, kiddo.

We need to think like Taylor.

She'd say the answers are in the details.

But what details?

Everything was fine this morning until... The lost cave. We need to go

everything we did then and since.

My phone!

The dead section stops there, on the west coast, near the cliff.

That's where the lost caves were.

There was this cool rock outside and the birds were singing.

Then we went inside.

I'm standing in the lost caves of Gaia and guess what's here?

I know what you're thinking.

What kind of island mysteriousness is this?

In other words, these beautiful creatures were born this way.

Then there was this weird sound.

So we went back outside.

What happened to the rock?

According to Sonny, it died the day they invented disco.

Then I went home.

And you were there.

Everything that's changed has changed since we went inside the cave.

So what does that mean?

The Lost Caves! They're it!

How? What if the Lost Caves aren't glowworm caves? What if they're glowworm

wormholes?

It's like we've been transported through some kind of... Portal.

Are you saying that Uncle Charlie has come from a parallel world?

No.

We have, and our presence is killing this world because we're not supposed to

here.

Since we've been here, the birds have gone.

The reef is dying.

The jungle.

Everything.

We have to go back.

Well, how?

Theoretically, a wormhole works as a bridge between different universes.

So we go back across the bridge, which is a cave.

From what I understand, you need to retrace the steps in reverse.

Otherwise you risk entering another parallel universe.

One with insect overlords. Or one where the effects might be worse than here.

It wouldn't be safe.

For anyone.

And Uncle Charlie has to make sure the cave entrance is closed.

So no one can access the wormhole again.

Even me.

But it's so great having you back.

We'll find each other again.

We just need to find the right way.

Come on.

I'm so proud of the person you've become.

I miss you so much.

Don't give up on me.

I'm out there somewhere.

Solve my mystery.

Okay, so what was the last thing we did in the cave?

Alice ran into the wall.

After the womp.

We'd better do it to be on the safe side.

Fine, but only because I don't want insect overlords.

Ow!

Drongo, check.

Rock, check.

Where to next?

Here goes nothing.

Plants.

Check.

Fruit.

Check.

Hey, how was your day?

Amazing.

How was yours?

Same old.

Work, groceries. You know the routine.

Hey.

You okay, huh?

Just missing Uncle Charlie.

It's been five years.

I still miss him every day, too.

I need to go somewhere.

Okay. Bye, Mom.

Hey. Look what I found.

I know I'll find you.

I'm sorry you had to say goodbye.

No need to be. It was the best day of my life.

And like Uncle Charlie said, we'll see each other again.

Mysteries.
