Hawaii Five-0

- Hey. -Where's my girl?

Good morning to you, too.

Yo!

Uncle Steve.

- Steve. - What's up? What's up?

Don't do that. Don't get up.

Don't get up. Stay right there. Oh, hi, hi, hi.

- How you doing? - Good.

- Good. You look good. You look good. - Thank you.

How's Pops doing? Is he looking after you okay while Mom's away?

That's a silly question. Of course I am.

- Whoa, hey. - What?

What's the matter with you? What are you, an animal?

- Just want a little piece. - She's, uh, recovering

from a serious accident.

You don't need pancakes. She needs pancakes.

Sit down and relax.

Eat up, so you can get back in bed.

But I'm not at all tired or hungry.

- Yay! Oh, whoa, whoa, whoa, whoa.

Please put the, uh, plate back in front of my daughter, please.

Thank you. Okay, here's the thing.

Doctor said you got to eat a lot of food,

you got to get a lot of rest, and you'll feel like

a nice young lady again, you'll feel normal,

like a person, so please eat your pancakes.

Okay. But, Dad, I was actually feeling a little cold.

Could you get me my sweatshirt?

Please?

You're cold?

You don't have a fever or nothing.

All right. Don't touch her pancakes, you animal.

Please. You got to do something. He's driving me crazy.

- It's that bad? - Yeah.

He's all up in my business all day.

Checking up on me, bringing me food.

So much soup.

- Soup? He's doing soup? - Soup.

Matzo ball?

Oy, he's like a Jewish grandmother with that stuff.

All right, look, Gracie, here's the thing.

When you were in the hospital,

Danno was really upset, of course.

He felt helpless, there was nothing he could do.

He just had to sit there and wait for the news,

but now that he's got you

back home, he wants to take care of you, you know?

And he's gonna do everything he can to get you

back on your feet. He loves you, you know.

- And I love him for that. - Hmm.

But if you could just get him out of here,

even for a few hours.

- Give me one of those pancakes. Hey.

What's the matter with you? Why aren't you eating? Huh?

I was waiting for you.

You were waiting for me so you could start eating?

- Yeah. Yeah. - Eat. Come on.

You want me to butter your pancakes like you're six?

Yeah.

You never butter my pancakes.

Yeah. McGarrett.

Yeah, I'm with him right now. We'll be right there.

"We"? What's "we"?

I need you, buddy. I just got a homicide.

I'm gonna need you on this one.

I'm so sorry. Grace, are you gonna be okay if I take him?

Aw. You go.

I'll be okay, but I was really

looking forward to spending the day with you, Daddy.

Me, too, Monkey. Eat, please.

: Thank you.

So, uh...

you've been spending a lot of time with Rachel, huh?

Yeah. We're taking care of our daughter

who was in a near-fatal car accident.

Uh-huh. I'm just saying, this whole, uh,

this whole "playing house" thing,

wondering how much it's got to do with...

Rachel as well as Grace. What's going on there?

I... Nothing's going on. I mean, we don't want

to kill each other for the first time in a long time.

Is that... is that all right with you, or...?

Yeah! Yeah, yeah, yeah.

I-I'm just wondering if you've thought about, maybe,

what the plan is, you know?

No. No, no. No plan. It's not, uh...

it's not like a special op, you know what I mean?

There's no... no specific plan.

So it's just, it's, uh, freestyling,

you're freestyling, like, relationship jazz?

Yeah, I'm basically Miles Davis.

Noelani, good morning.

Commander McGarrett, Detective Williams.

Glad I didn't let you eat those pancakes.

Why?

'Cause of him?

Oh, I don't have a weak stomach like you.

Uh, sorry. What do we know so far?

John Doe. Couple surfers found him this morning.

Throat was slashed. My stethoscope camera

indicated no water in the lungs,

which means he was dead before he hit the water.

No, I don't think this guy was killed and thrown

in the ocean; I think he was

killed at the bottom of the ocean. - Really?

Commander McGarrett's right. The internal bleeding

and marbling of the skin are signs of sudden

and massive decompression.

Decompression. So, like, he came up too quick

and got the bends?

Exactly. The rapid change of pressure

causes the nitrogen in the body to separate,

forming bubbles in the blood, wreaking havoc

on the internal organs. It's like when you

shake up a bottle of soda and then remove the cap.

This guy literally exploded from the inside.

And decompression-- or rather

a lack of decompression-- this severe means this guy

had to have been deep.

I mean, at least 150 feet plus,

and he had to have stayed there for a prolonged period of time.

All right, so where's his dive gear?

I mean, the guy looks like he's ready

for his shift at Banana Republic.

That's a really good point.

The guy's not wearing any dive gear, so what

was he doing on the bottom of the ocean?

Hey, what are you doing?

Hey!

I guess Mom didn't tell you I was coming over.

She told me you might need a hand with this deck.

- Wrong. - Are you sure? 'Cause...

it looks like nothing's changed

since the last time I was here at Thanksgiving.

You brought the wrong wood.

It's red cedar. It'll last longer.

Sure. It'll take me days

to power-wash and re-coat every year,

but that's not your problem, is it?

You're never here, anyway.

- I'm here now. - Hm. Yeah,

until you make up some excuse to go run off.

You and your, uh, busy schedule.

All right.

You know what, Dad?

This time, I don't need an excuse to leave.

You're enough.

Victim's name is Jason Kamaka.

He was a professor of oceanography at Oahu State.

That is until three months ago, when he took a leave of absence

to work on this project.

The Neptune One. It's a deep-sea research lab.

Okay, well, now we know what our victim

was doing on the bottom of the ocean.

Oof. I thought my commute was bad.

The Neptune's crew is six weeks into a two-month mission,

and they are studying the effects the Kilauea's lava flow

has on marine ecosystems.

Everything was put together by this guy.

Who's he?

Claude Nostromo. Guy made his fortune

in database software

and cloud engineering systems. Now his company has interests

in everything from rockets to hydrogen fuel

to the Neptune One.

This thing's on the bottom of the ocean,

completely cut off from the outside world,

which means our victim had to have been killed

by one of four people, no?

So you're saying that this murder could've been

over lava research?

I don't know. Maybe. I don't know what it was over.

But here's the thing.

There are some other factors to take into consideration.

I mean, these guys are in

serious close quarters for long periods of time.

That can make anybody crazy.

Plus, you got the depth factor and what that does to the brain.

Something called high-pressure nervous syndrome.

I'm talking about paranoia,

hallucinations, delusions.

Before you know it,

you got a highly combustible situation down there.

This is unbelievable.

I mean, with projects like this,

y-you make contingencies for every possible situation.

Truly, I never could've imagined that...

Murder. Yeah, that's

a crazy one. Mr. Nostromo,

when was the last time you heard from the Neptune One?

- We lost contact 12 hours ago. - I'm sorry, 12 hours?

No, I mean, it's... Because of the depth,

it's not uncommon to go several hours without contact,

but usually the comms are restored relatively quickly, which is...

I mean, given the circumstances,

uh, your communication problem's

probably not a coincidence, right?

Somebody just killed Dr. Kamaka,
