Siren

- Previously... - I made a choice in the water.

- I had a chance to save him. - You let him die.

- So, what does this mean? - I don't know.

It feels different now.

Robb Wellens started this project

to clean plastic from the ocean.

Do you want to grab a bite, and I could tell you about the energy data?

What is it? Application for the Sheriff's Academy.

Fill out the paperwork, hand it in end of day.

The procedure went exceptionally well.

They implanted the first embryo in you.

A mermaid baby isn't compatible in a human body.

Sarge, he was trying to tell me something. What does it mean?

War is coming.

You're suggesting we continue the treatments at an increased dosage.

- We extracted them from Ryn's sister. - After you dug up her grave.

My God.

It's only half transformed.

We buried her.

She is one from another tribe.

I will put an end to these humans,

and to you if you interfere.

- It's really bad - She's strong.

Stronger than any I've ever seen.

Stronger than Ryn.

Ryn!

You need to rest.

No. No rest.

Your body needs time to heal.

Okay, come on.

Before, it did not take me so long to heal.

Why?

Your injuries were very bad this time.

I fight hard before.

This is different.

Maybe because I am human for so long.

Harder to heal.

That's possible.

Ryn, you should know.

I saw Sarge again.

I went to the ocean.

I saw him under the water.

He told me war is coming.

It is her.

I must be ready.

For 50 years this milk crate was floating in the ocean.

I couldn't believe it.

And this is boring the crap out of you.

No, sorry.

It's just been a crazy couple of days.

I know I talk a lot,

but I'm actually not a bad listener.

A friend of mine got hurt.

She should be fine, but I've been helping her out.

Sorry to hear that.

Yeah. I appreciate you being cool with a quick coffee.

Of course. Of course.

I like you.

And I want to get to know you, at whatever pace.

But sometimes I come on too strong,

like a socially inept dork.

Just tell me to back off.

I like socially inept dorks.

Would you want to go with me to do...

to do a gyre cleanup?

Did you just invite me on a date to a garbage pile?

Not a date,

though that would be quite romantic.

No...

as colleagues.

It'd be amazing to go, see the project in action.

You had some great thoughts the other night,

about how to tweak the machine.

I like how your brain works.

Look, just think about it.

Let's go, McClure. We don't have all day.

McClure!

Drop your weapon!

I'm not going down for this!

We can still end this peacefully.

Just put your gun down and slide it over!

Come and get it!

Come on, McClure. Focus.

Xander, wait!

Bang, bang!

McClure, you're dead.

You can't take your eyes off the prize, people.

Every day, you're on the front line.

You're going to see some crazy shit.

You're the one between innocent people getting hurt

and a total free-for-all.

All right, sprints!

McClure.

Go.

That's it. All the way down.

Good.

Just one more.

- Good, Elaine. - Wow, Mom.

- Look at you. - Hey.

What a nice surprise.

I'll de done in a minute.

All right. Let's get you seated.

You said you wanted to talk to me?

Yeah, let's go out here.

All right, I'll get the TheraBand.

I...

I think I should try standing.

Let's take it slow.

We just got your upper body strength up.

I have some questions about this study.

What they've been putting in your mother.

Stem cells from some deep-sea marine creature.

Is it one of them?

It's working, Dad.

You... you knew, and you let them anyway?

We didn't have a lot of options.

You saw what she was like.

She was dying.

You didn't know what it would do to her.

- It could've killed her. - But it didn't, did it?

I need to talk to Commander Kyle about this.

Kyle's not in charge anymore.

There's been a change of command.

Look, I'm not even sure if the treatment can continue.

What's going on?

- What? - Mom!

- Elaine! Get her, get her! - Mom! Mom!

My God! Get her!

- Elaine. - My God! Elaine!

What the hell happened? Baby, what happened?

Everyone relax.

- Are you okay? - Yes, I'm fine.

How long were you under?

I don't know.

A few minutes, maybe? It's okay.

A few minutes?

I'm okay.

Tia wants our territory,

but we cannot let her rule us.

The tribe is violent. Dangerous.

I must stop her.

- How? You are weak now. - You stay to help me heal.

And you. We will practice fighting on land.

Make me strong again.

I make medicine for you.

I can help.

Katrina and the others will stay in the water.

Guard against her.

They will wait and watch for her.

Tia will be going back to her tribe,

to lead them again.

I must be ready.

Attack like we fight in water.

Better if we fight in water.

First on land.

Then in water.

Anything you need, just help yourself.

I have bowls, a hand mixer,

measuring cups.

I bring this, to make our medicine.

Helpful and delicious.

You're doing great.

Okay...

Her body temp is too high for a mermaid baby.

But she can only stay in this ice bath

for a half-hour, max.

Then that's how long she'll stay.

If I could take her to my lab at the ranch.

No. No way.

Anyone finds out about this, they will keep her there.

If we do nothing, she could die.

She won't.

You won't let that happen.

You teach me to read.

Ryn, it might not be the best time.

Tia is more human than Ryn.

I must have knowledge to be more human.

Okay. I'll teach you to read.

But, you know, an easy way to get knowledge

is just to ask your phone.

What does phone know?

A lot of things.

How many bones are in the human body?

The human body includes 206 bones.

How many bones are in my body?

The human body includes 206 bones.

Phone does not know everything.

A.

B.

C.

"There are four different categories of..."

Oceanography.

It's like ocean and science.

You got the fish.

Great.

Everything okay. Is Ryn feeling better?

Yeah. All this spear fighting is making them hungry.

Ryn is determined to be as strong as Tia.

This is the medicine Eliza made.

She said it's supposed to help speed up her healing.
