Hey, Cam. Carly, great.
I need a kilo of tuna, a kilo of salmon,
as much shrimp as you've got.
What's the catch of the day? I think it's swordfish.
Throw in some of that too. While you're at it, some flake.
And I need it all delivered.
Are you having a party or something?
No.
Suddenly got a bit of a taste for it.
Be careful. You've been hanging around Zac too long.
Nixie. Hey, are you hungry?
I've just placed a delivery order—
Is it safe?
Of course.
I'll show you.
Okay.
And you're sure Zac doesn't know it's here?
Beyond sure.
He wouldn't think to look here.
And you're not gonna tell him?
Not a chance.
You have my word.
Thank you so much, Cam.
Then this is it.
Zac's gonna be back to normal,
and we can finally return to the pod.
This could never have happened without you.
What can I say?
I'm a rare find.
You know, Zac might not be too happy
with being turned back into a normal guy. Right?
We're not planning on giving him a choice.
Right?
Hey, girls.
Rita, there's something we wanna ask you.
Anything.
We want you to come with us tonight.
Back to the pod, be a real mermaid again.
After all, you've given us a lot of help.
I'm sure the council would let you back.
No.
Thank you, but no.
Look, you girls belong with the pod,
but Mako is not my home anymore.
My life's here now.
But it's not gonna be the same here without you.
I can't believe you lied to me.
And for such a long time.
I know.
That was wrong.
But I wanted to tell you so many times.
I never wanted to lie to you.
I was trying to protect you.
And them.
Yeah. And them.
This is all their fault.
No, it's not.
Why are you defending them?
I'm not. I'm just...
The whole thing was an accident.
Wrong place, wrong time. It's not their fault.
I don't believe that.
And I can't make you.
It's the truth.
Listen.
Evie...
Telling anyone would just be bad news
for me, as well as for them. You know that.
If you're gonna say something, could you just
wait until tomorrow?
Tonight's a full moon.
If it's not all back to normal by tomorrow,
then go ahead, shout it from the rooftops.
But until then, could you
keep it quiet?
Please?
Okay.
Fine.
I won't say anything until tomorrow.
Thanks.
Hi, Evie.
I know you're mad at me.
Understatement.
I can explain.
Really?
Then go ahead, Cam, explain.
Explain why you ganged up on me with Nixie.
Explain why you helped steal the Trident from me.
Explain how my so-called best friend of 15 years
could just turn on me with no warning.
I deserve that.
But we had to do something.
We thought the Trident was controlling you.
You told me about the dreams you're having.
We were trying to help.
Evie knows all about me, thanks to you.
I'm sorry, man.
Evie was collateral damage.
I didn't want her to get involved,
but I didn't have any choice.
I know you know that.
She did have a right to know.
And I did feel bad keeping it from her.
So...
Are you really gonna do it?
Give it all up?
Yeah, I am.
After tonight, I'm gonna be a normal guy.
No scales, no tail.
It's time to get back to my old life.
It's over.
The Trident is safe, I made absolutely sure of it.
The Trident was safe with Zac. You didn't need to interfere.
Well, I don't regret anything.
Then it's real.
We're leaving.
We're not really leaving.
We're going home to the pod.
No more land people.
No more legs.
Yes, but that's if Zac keeps his word.
Zac will keep his word.
It's not gonna be easy for him.
It'll be good to get back to the pod,
and I'm sure, in time,
we'll forget the things we've left behind.
Zac's here.
I spoke to Evie. She agreed to keep quiet until tomorrow.
So we're all set.
Well, that's assuming everyone
will keep to their side of the deal.
Everyone will.
I'll be back at moonrise.
How are you feeling, Sirena?
Ready for tonight?
As ready as I'll ever be.
So you've said your goodbyes, then?
Not exactly.
You haven't said goodbye to David?
I don't wanna hurt him.
I know it's hard.
I had to choose between two worlds too.
But sometimes the things we don't do
hurt more than the things we do.
Sirena, hey.
I have to tell you something.
Okay.
Whatever it is, it can't be as bad as you think.
Come on, out with it.
I'm going away.
Away?
A long way away.
I'm guessing this isn't just a weekend thing.
No.
I won't be back.
Isn't this a bit sudden?
It's been a long time coming,
but I guess I just really wasn't prepared.
I know the feeling.
I'm so sorry, David.
I can't explain,
but I should have warned you that this might happen.
I really didn't wanna believe it.
We can stay in touch.
There's always the Internet and phones.
We can write and talk. No, we can't.
I don't understand.
After today, we're never gonna see each other.
Goodbye, David.
Sirena, wait!
Let's go.
We need to talk.
Sirena...
Will you be okay if I leave you alone for a minute?
Those mermaids have got Zac completely fooled.
Tell me something I don't know.
The sooner he gets turned back into normal Zac, the better.
No, that's it.
They're not gonna turn him back into a normal guy.
Not tonight, not ever.
But they have to! No, it's not gonna happen.
They want him for their pod.
Tonight is a full moon.
They're gonna turn Zac into a merman forever.
We have to do something. Yeah. We do. Come on.
Cam tricked you, Nixie.
He's scheming behind our backs. He has been this whole time.
You can't trust him. You're wrong.
Nixie, you have to believe me.
I heard him talking to Evie.
He's up to something.
What if he's not? How can you know for sure?
Fine. Don't believe me.
I'll prove it to both of you.
Show me where he's hiding the Trident.
Evie, what are you doing here?
Do I need a reason?
It's just...
I have to go. It's nearly time.
You can't go out there.
You're walking into a trap, they've got you fooled.
Look,
I know you don't like them, but they're on my side.
Now, I have to go. No!
Evie, move. No!
I really have to go.
If you go to Mako, our deal is off.
I'll tell everyone about them and you.
You wouldn't do that.
I'm sorry, Zac.
But I will.
It's right here.
He lied to me. He actually lied to me.
I'm sorry, Nixie.
Why did Cam lie to Evie?
He's using her to stop Zac going to Mako.
Yeah. He wants this all to himself.
Cam's always been jealous of Zac's powers.
Cam wants to be a merman. We've got to do something.
If he takes the Trident into the moon pool—
No, don't worry, Sirena. I'm not gonna let this happen. Okay?
Are you kidding me? There's just one thing we need.
Why are you doing this?
I know those girls. I know I can trust them.
You're wrong, Zac.
Cam said that— Cam?
What's Cam got to do with it?
He said that they wanna make you like this forever.
Cam said that?
Whose idea was it to go to Mako to get the Trident from me?
Cam's.
Right. And who has the Trident? Now?
Cam.
Who planted the seed of information
into your head earlier today
to try to get you to stop me from going to Mako tonight?
Cam.
I have to go.
What are you doing? Yes, what are you doing?
Rita, I have made a huge mistake.
But we really need these right now.
Cam is out there with the Trident,
and we have to stop him.
I know we haven't finished much of our training,
but I'll understand any punishment that follows.
We're taking these.
So, what are you waiting for?
Thank you.
Don't do this.
You're too late.
I'm gonna do what you couldn't do.
You're making a big mistake.
You're wasting your breath.
Come on, Cam.
Put it down.
We don't belong here.
Speak for yourself.
You could get hurt.
Seriously hurt.
You take that thing in there, it will destroy everything.
Do you remember that night we camped here?
It should have been me.
Not you.
I won't let you do this.
I'm not asking your permission.
You had your chance,
and you gave it up.
But I'm not going to.
This was meant to happen, Zac.
You can't stop it.
Give it to me!
You shouldn't have done that.
You can't stop me!
What's going on?
I don't know.
I think my moon ring's losing power.
It's the Trident.
It's stronger than our moon rings.
Hold on, Nixie!
You're no match for me!
Lost something?
Guess we have to give these back to you now.
No.
I remember three young mermaids who were banished from the pod
for failing to protect the moon pool.
But no one could have protected the pool as well as you have.
Today, I see three mermaids
who saved the moon pool from destruction.
The pod would be as proud of you as I am.
Now,
I know there's a journey ahead,
but all three of you have earned your moon rings.
Sorry, we're not open yet.
I'll wait.
Sirena?
I don't understand.
I thought you were...?
Does this mean...?
I thought I'd stay a little bit longer, if that's okay.
It's more than okay.
I was in the moon pool during the full moon,
and I didn't change back.
You realize this means that you're stuck dating a merman
for a little while longer.
Well, it's lucky that I love you for who you are,
not what you are.
Somebody get me a bucket.
I was hoping to see you three today.
I wanted to apologize.
I shouldn't have judged you so quickly,
and I really am sorry.
I should have trusted you.
It's all history now, Evie.
Go on, go.
I'd race you to Mako,
but let's face it, you're too slow.
Dream on, mer-boy. I can out-swim you any day.
So can I. Me too.
