Fortitude

Well, it's the beginnings of a pattern.

And Shirley attacked

and attempted to kill her mother.

Vincent: We don't see that happen.

It's psychotic.

We're only looking for a body now.

Vincent: The toxins accumulate

in apex predators.

Shirley Allerdyce was an apex predator.

Frank! Oh, my God.

If I don't get the truth, they'll take Liam.

Who was there when Bill Pettigrew died? Come on, Henry.

You'll have to accept

that there's some things we'll never understand.

Morton: When's he coming back? I'd like to talk to him.

He's not coming back, is he?

( Classical music playing over headphones )

Elena!

Elena: What?

- Are you... Oh. - ( Phone rings )

- ( Piano notes playing ) - ( Phone rings )

Midnight Sun Hotel. How can I help you?

Yeah, hello. I'm trying to get hold of DCI Morton.

Do you know where he is?

He's out.

If you see him, could you tell him...

Tell him to call his office.

Of course. Of course I will. Thank you. Bye.

- ( Barks ) - Shh, shh.

Would you like me to take you to the medical center?

Shh, shh, shh, shh.

You called the police?

Is that why you're here?

No. I wanted to make sure you're okay.

Not okay. I know that...

Well, I'm not okay, Mrs. Sutter.

I'm very far from okay.

When someone behaves the way your husband did, though...

- ( Whimpering ) - Shh, shh, shh, shh, shh...

Consequences are inevitable.

He's all right, isn't he?

I don't know.

I don't know.

So tech department

have enhanced this GPR scan,

and you won't believe what Pettigrew found.

Those squiggly lines are bones,

animal remains, and tusks,

an elephant's graveyard of mammoth beasts,

a hoard of ivory underneath the ice

worth a bloody fortune.

So call me when you surface.

They're here.

Hildur: Thank you for coming.

Please have a seat.

I want to talk to you about something

that affects Liam very much.

Liam?

What I'm about to say is sensitive,

so I need your word that you won't talk about this to anyone.

Okay.

It's been suggested that there are

some kind of environmental toxins on this island,

and it may be possible

that Liam's been affected.

Now, we want to see

if there are any of these toxins in Liam's brain,

and in order to do that,

we need to take a little fluid from his spine.

No, I'm sorry. I don't think he's ready for that, not now.

As I understand it,

it's not a complicated procedure.

It's over in a couple of minutes.

I know how difficult this must be.

How?

How would you know that, Governor?

We need to understand what made Liam

attack Professor Stoddart.

Because it may still be affecting him.

He may not be getting any better.

If we found that a chemical

had altered Liam's behavior,

then that would change everything.

It would mean that what happened

wasn't Liam's fault.

I am here to see Shirley.

The medical center said she was here.

Why was she moved?

We needed to perform some tests.

This place is for animals.

I'm sorry.

I need to see her.

Der na.

Min stakkars vakker.

Postmortems are usually performed

on the victim of a crime, not the perpetrator.

These were exceptional circumstances.

I can tell you now

there was no violence in Shirley,

none at all.

What happens when you are finished?

She's released to the family.

There is only her mother.

Then I don't know.

No one seems to.

What were you whispering about?

Whispering?

You and Dan were

earlier today.

Yes. Um...

What was it?

Dan thinks...

that we have to be prepared for the worst.

What?

Is it your father's?

Yeah.

I'm so sorry, Carrie.

No. Just get off of me.

Don't say that!

He's not dead! He's not!

My dad wouldn't leave me! He's coming home!

- ( Knocks ) - Carrie.

Carrie.

Open the door, please.

- Carrie. - ( Ronnie gasping )

Vincent: Liam, this is gonna hurt a bit, okay?

Won't be for long.

- ( Moans ) - Shh, shh, shh, shh.

It's okay. It's okay.

Good boy.

It's okay.

- ( Wails ) - Breathe.

- ( Liam groans ) - Shh.

Hold still, sweetie.

It's nearly over.

- ( Groaning ) - Stay still.

Just breathe.

Keep still.

Keep still.

- ( Groans ) - Thanks.

That's all.

Nearly there.

How's it look?

They're negative.

Absolutely no trace of PFAs in Liam's system.

Shirley's levels are through the roof.

Yep. Well, maybe it was her diet,

maybe how long she's lived here.

Maybe children process PFAs differently.

I don't know.

I don't know enough.

We hurt a little boy.

Well, this is something we've eliminated.

We move on.

We rerun the data

with a different set of search criteria.

Yep.

I need some air.

Daddy's home.

Hanna, don't drag your bag.

Celia: Jason.

Jase?

Where's daddy?

He's... He's out.

Go and get the rest of the stuff out the car, love.

Jason!

Baby.

What happened?

What do you think you're doing?

That sound he made.

Mr. Sutter.

Sounded like an animal caught in a trap.

I can't imagine being a dad

and having to submit your own child to pain like that.

I'm just not...

What?

I came here to do research for my PhD,

not inject children

and witness a murder and...

Liam Sutter had an illness...

and was seen by Dr. Allerdyce.
