Siren

Previously on Siren...

Non-human blood?

You mean, like an animal or something?

-Everything okay? -Yeah, just a case I'm working on.

I went out to confront her.

Hyah!

And she threw a damn metal pole at me.

- Hey! - I got a text from Chris.

Donna Stevenson lives in Bremerton.

Says she's a registered nurse.

What's happening?

Where the hell are we?

On some kind of military fort?

Go! Go, go, go, go, go!

That's her.

Steady.

Security breach, Zone One.

Repeat, Zone One security breach.

Follow protocol for system-wide lockdown.

This is a Stage One lockdown.

Security breach in the Med Lab.

All personnel observe lockdown protocol.

Keep the perimeter!

Clear! Movin' up!

- Clear! - Go! Go!

This is a Stage One lockdown.

Security breach...

Come on.

Come on. Let's get out of here, okay?

Security breach in the Med Lab.

-All personnel observe lockdown protocol. -Go!

Watch your corners!

Stage One lockdown.

Security breach in the Med Lab.

Go, go! Go, go, go!

Security breach in the Med Lab.

All personnel observe lockdown protocol.

Which one is yours?

The car?

Which car?

It's the keys, okay?

Come on.

Go on.

Go!

Come on!

Come on. If you're comin', get in!

Come on!

I think she's not coming home tonight, is she?

Probably working the night shift.

Chris is gonna be okay, right?

We're gonna see him again?

Count on it.

He's a total badass.

Tough as they come.

Yeah.

We'll get Donna when she comes home.

Make her take us to Chris.

Couldn't sleep?

Too much on my mind.

Me, too.

Got room for one more?

Ryn!

Xander, give me a call when you get this.

Let me know what's happening.

He thinks he found Chris?

He tracked down that nurse whose phone Chris used.

They were following her.

- Sister? - Maybe.

Yeah, if we find Chris, there's a chance

she'll be in the same place.

Ben, look.

She's been out of the water for a couple of days now.

Last time, it only took a day

till she started drying out.

Seems like she's able to stay on land longer.

You like it?

Moon.

It's Xander.

Hey.

Yeah?

No way.

Where are you?

I'll be right there.

They followed that nurse to some military facility,

got chased away.

They're staked out in front of her house in Bremerton.

Hey, wait. I'm going with you.

- Maddie. - Ben, don't even.

Me go.

Ryn, I don't think that's a good idea.

This place, it's very far from here.

On land. You'd be trapped

if you needed to go back into the ocean.

Look, if we find your sister,

we'll bring her to you.

We promise.

We can't just leave her here.

You know, this is the worst coffee in town.

I know, you say that every morning.

I'm a creature of habit.

That's one word for it.

Morning, Sheriff.

Hey, Janine.

You recover from last night?

Didn't even have a chance

to get a buzz on before you guys showed up,

ruined all the fun.

Serve and protect.

Jerry's gonna manage that motel right into the ground.

Delicious as always.

You happen to see this girl?

Janine, you have a look.

No. No, never seen her.

What's the deal with her?

Just asking if you seen her.

We weren't formally introduced or anything,

but, yeah, I saw her at the party last night.

She was with Maddie.

I wonder why she can't just get in the water

then get back out like last time?

It's not that simple.

You saw the video.

Her bones crack. It's agonizing.

I just wish we knew how long she can last.

The stories handed down

say they can stay longer and longer

each time they come to land.

I will wait

for sister.

I can't say for sure we're gonna find her.

Okay? We don't know.

I wait.

Stubborn creatures, aren't they?

Maddie?

Let's go.

Let's see what we can do about your skin.

Where are we?

This area, I don't know it.

So what was that place?

Some kind of prison?

Hey, are you all right?

We need to get you to a hospital, or...

I think you might be in shock.

My name's Chris, by the way.

Donna?

You know, I had a nurse in there named Donna?

We called you as soon as we secured the site, sir.

This is how we found it.

Any survivors?

None, sir.

When Ryn goes back in the water,

I want to put a tracking unit on her.

What?

I don't... I don't know.

I'm not sure how I feel about that.

She's not one of our sea lions.

I know.

What are we saying if we ask her to do that?

I just... I wanna know what she's doing out there.

Her dive rate, range, velocity.

Yeah, I get it. I do. And I want to know, too,

but, babe, she trusts us.

I want her to know we don't think of her

as some kind of experiment.

She knows that.

This way, we can look out for her,

make sure she's safe if she gets caught.

We owe that to her.

I don't want to just let her go.

This should help for a little while.

It's castor oil, sea salt,

buttermilk, and Boswellia.

Old family recipe.

I wouldn't eat that if...

Can't say I didn't warn you.

They call it an autoimmune response.

That's the word they use

when they don't understand what something is.

You have to sit still for a little while.

Let it soak in.

Why did you and your sister come so close to the surface?

You know better.

I'm sure you've been warned.

Food.

Hey, wake up.

I wasn't sleeping.

Yeah, we were surveilling.

It's 10 AM.

She should have been home by now.

Maybe she's working a double.

Well, we can't just sit here.

You got a better idea?

Yeah, let's get in there,

figure out who the hell she is.

They teach you that in college?

No, grad school.

What are we looking for?

Anything to do with Chris, that facility, this nurse.

She's got a serious thing for pigs.

Hey, check this out.
