Hey.
What... What are you doing?
You said I should drop by.
Yeah, well, I figured you'd look a little more... normal.
Relax. I know what I'm doing.
Well, your mermaid friends wouldn't be happy,
- you flaunting your tail like this. - They trust me.
And so will the rest of their pod as soon as they hear
what a harmless dude I am.
- Someone's coming.
I know what we were taught about mermen,
but you have to believe me.
Zac's no threat. He's harmless.
Sirena, we've had this discussion.
If he wasn't a threat, the pod would not have fled Mako.
But he's our friend.
Just ask Nixie and Lyla.
They've gone to join the search for a new home.
The pod can't stay here in the open ocean.
Zac proved himself. He destroyed the Trident.
There are things you don't understand.
Tonight, the merman will enter the seventh cycle of the moon.
His connection to Mako will deepen.
He won't be able to help himself.
Like it or not, he is an enemy...
to all mermaids.
We have to do something about this merman.
We tried.
He was in the moon pool during the full moon
and he didn't lose his powers.
Maybe he wasn't in there long enough.
Exactly.
You may have tried, but Mimmi and I haven't.
Ondina, whatever you are suggesting,
the mermaid council will never agree.
I know.
That's why we're not going to ask them.
Hey, gorgeous.
Why are you so cheerful?
It's a full moon tonight.
Relax, I've been through it before.
Still...
Evie, I can handle it.
Hey, Evie. What can I get you?
Oh, this is Erik.
He's new. He started this morning.
- Erik, this is... -Zac. I know. I've heard about you.
It's good to meet you.
- I'll have a tropical juice. Thanks. - Same.
You got it.
I wish you two would work it out.
I've tried.
What is this place? Somewhere safe.
- Is the boy here? No.
There's something you need before you meet him.
Legs?
If you're going to talk to Zac, then you've got to get them, too.
I don't understand
how land people manage on these stupid... things!
A mermaid lives here.
Her name's Rita. She's a friend.
- A cat!
Hey, Poseidon, I've missed you.
Come here.
He won't hurt you.
Poseidon's a friend like Zac.
There you go.
Where's the boy?
You do realize land people are different?
Look, just follow my lead
and try not to do anything to stand out.
Sure. We'll fit in just fine.
- That's him. Him?
He's not going to be a problem.
I'll introduce you.
Sirena!
It's so good to see you.
David, it's so good to see you, too.
Sirena says you're harmless.
Excuse me?
If you do what we tell you, you'll be fine.
And then everything can go back to normal.
Oh, so, you're...
I'm Ondina. She's Mimmi.
Hello.
We've come to solve your problem.
You go back to being a land boy, the pod returns to Mako.
Everybody's happy.
Except I'm happy the way I am.
Hi, what can I get you?
Fish burger, thanks.
Ladies? - What?
Uh, something to eat? Something to drink?
I bet you're coconut smoothie girls.
Serves in a coconut shell with a straw and a cute little umbrella.
Delicious.
As I was saying...
Guys, I appreciate you coming all this way,
but there's really nothing to worry about.
I've been thinking about you a lot.
In fact, I've even written some new songs...
about you.
Really?
Hey, Zac, the shirt I ordered for you came in.
- Try it on. - Great timing. Thank you.
Obviously, we need to be more direct.
Let me try.
What my friend was trying to explain is...
- Do you mind! - Not at all.
The seventh full moon cycle is very significant.
The island will start to control you...
Excuse me, can we discuss this outside?
Probably better in here. You're not properly dressed.
The thing is,
you'll be drawn to the island but you mustn't let it happen!
You've got to stay with us.
You will need our help to resist the pull of the...
Thanks, but I don't need your help.
I can control my own powers, thank you.
I'll try it on later, thanks.
He still won't listen.
What's the matter with him?
What happened?
Thank you.
Maybe I haven't been clear.
Tonight, you're going to do exactly as we say.
The thing is...
I like to make up my own mind. I don't take orders from you.
Enjoy.
I think it might be better if you went home.
That's what I'm trying to do.
Are we...
Yes.
Well, I guess they just... really needed to cool off.
What were they on about?
What's a seventh moon cycle?
There are legends that speak of a sudden escalation in merman powers,
but no one knows for certain.
You see? This is all an overreaction.
So, tonight's a full moon. Big deal.
I've already been through, like, six of them, and I'm fine.
Zac, if there's even a possibility those mermaids are correct,
you need to be extra careful.
Promise me you won't go out to Mako.
- Evie... - Promise.
All right.
I'll stay with you the whole time.
You happy?
I told you to be careful.
He attacked me!
You started it.
The boy is not going to listen to us.
We have to look after him tonight.
It's getting dark.
Where will he be?
Probably at the café. I'm gonna be singing.
Why?
David asked me.
He's written songs about me. I'm supposed to be rehearsing.
Do that.
We'll meet you there.
Don't do anything without checking with me first.
You're up to something.
I think I know how we can break the boy's connection to Mako.
- One Mediterranean. - Thank you.
How was the swim?
Fine. Why?
Jumping off a customer's table
isn't the normal way to get into the water.
Life's no fun if you're normal all the time.
You okay?
Yeah, I'm fine.
Sea urchin spines.
- Ambergris.
Do you know how powerful this is?
What is it, Poseidon?
Zac?
Got it?
Rita had everything I needed.
Sirena said he wasn't affected by the power of one full moon, but...
when he's hit by the power of 50, he won't stand a chance.
Zac?
I told you, I'm fine.
What's happening?
♪ Back with me... ♪ - It's starting.
- Do you want a drink? - Please.
Be right back.
- I need to get out of here. - Not without me.
I just need some fresh air.
I'll be right back.
Whoa, whoa, whoa, whoa. What's up?
Zac's being drawn to Mako. We can't let him go there.
Come on!
Zac?
I need to get to Mako.
You said you had it under control.
Come back with us.
Come on, man. It's too dangerous.
This has nothing to do with you.
I know we've had our differences,
but you need to come back inside.
- Don't tell me what I need. - Take it easy.
Zac!
You want him to go.
Sirena?
What are they gonna do to him?
I don't know. They didn't tell me.
Cam, we're going after him.
Whatever happened between you, get over it.
Zac needs our help.
I'm coming with you.
Sirena!
I thought you bailed on me.
You ready for the next song?
Hey! That's my boat.
This is my island. Leave.
Your island?
- You heard me. - We'll see about that.
What's going on? Who are those fish chicks?
Where is the entrance to that pool that Zac talked about?
Under a rock ledge about three meters down.
What are you doing? Evie!
Get ready.
Now.
- Zac. - Evie?
Evie! What have you done? Evie!
Evie! Evie!
Evie! Evie, come on! Evie.
Evie!
Zac!
Are you okay?
What happened last night?
Nothing.
Mimmi's potion didn't work.
I don't understand.
He was hit with the force of 50 moons.
- Maybe the girl affected its power. - What girl?
The boy wasn't the only land person in the moon pool.
Evie?
She was in the moon pool under a full moon?
- You don't think...
Hey.
How are you doing?
I'm fine. It's you that I'm worried about.
What were they trying to do to you?
Well, whatever it was, they blew it.
You were so brave last night.
But you shouldn't have put yourself in danger.
Now, are you okay... with the whole...
water thing?
How many times do I have to tell you?
I'm totally fine.
I even had a shower this morning.
See?
- Ahh! - Whoa.
Zac!
Evie.
What have you done?
