Grey's Anatomy

Meredith: In a recent experiment...

...scientists observed that single human cells

in a Petri dish will actually seek each other out...

...and adhere to each other to form new connections.

Trying to be the first one in?

I was.

I'm always first.

When cells team up...

Big day.

...they become stronger.Big day.

They thrive and evolve and eventually become something

bigger than their single selves ever could have been.

Morning, Winston.

Uh, Dr. Webber.

Uh, I-I married you and Maggie,

so, you -- you can call me Richard.

Right. Richard.

Ah.

Uh, how's Maggie's father?

Oh, he's better. Ah.

Yeah, yeah. I'm hoping to go out there next week.

Ah.

How's the Webber Method coming along?Morning, Dr. Webber!

Zander: We were just wondering what we should be prepared for today.

Sara: Which O.R. to be in.And what surgeries we're doing.

Please and thank you.

I'd say the method is going pretty well.

Let's move!

Megan: Okay. Don't forget to breathe.

M-Mom, Mom, stop worrying.

Dr. Hayes says Dr. Ndugu is the best in the country.

Other people think so, too.

I looked them up.I'm not worried, my love.

And, also, people don't like being told

that they were background checked.

I'm so sorry. It's all right.

Dr. Hayes and the Internet are absolutely right.

I'm good.

You ready to roll?Yeah.

All right.Okay.

-I will see you later. -Yep.

Bye-bye.

Bye.

All right.

You might want to go and get something to eat.

Pericardiectomy can take five, six hours.

Complex procedure.

Where you remove the calcified pericardium

that's been constricting his heart for God knows how long.

What kind of surgeon-slash-mom did you think I was

if I didn't know that?

I know. Just protocol.

You talk to your brother yet?

Or were the curtains closed because this is one of those

"secret" heart surgeries that Grey-Sloan

is so well known for?

What, you have one drink with a guy,

and you're suddenly in the "no secrets" zone?

Don't you think this relationship

is moving kinda fast?

I'll talk to him. Today.

Now.

Take good care of him, or I'll come back and kill you.

Thank you.

No, but, seriously, I have the training.

Owen: Unfortunately, the VA is still stonewalling

on your coverage, but we are making progress here.

Teddy: Yeah, we now have chest X-rays, blood samples,

and pulmonary function tests on almost everyone.

Except Noah.

Since Colonel Davis passed, Major Hunt --

Doctor. Dr. Hunt.Sorry. Dr. Hunt.

Since the colonel died, no one's heard from Noah yet.

He thinks it's my fault that Roy died.

He's not the only one.

Megan: Uh...

You two have a sec?Yeah, we're done here.

We'll be back and update you later, okay?

Oh! Get down! Get down! Get down right now!

Teddy: Get away from the windows!

-Are we under attack?! -Shh. Quiet, quiet.

What the hell was that?

Okay. All right. Thank you.

Scout and Luna --I-I just called daycare.

Everyone's fine. Scout barely woke up.

Are you okay? Yeah.

What was that? I don't know.

Hope it doesn't happen again.

Hunt wants everyone in the ER.

Have we heard what happened?

I'm trying to call Ben, but he's not picking up.

Owen: We need to activate mass casualty protocol.

We need to start setting up beds

and make sure we have enough blood.

Schmitt, grab another resident.

Prep the trauma rooms, cancel elective surgeries,

and tell the O.R.s to be on standby.

Private, Corporal, help us set up

a triage station outside, A.S.A.P.Yes, sir.

Owen, they're not medical personnel.

They're patients, and they're not in 100% health.

They're also soldiers who have trained for these kind of events.

In a few minutes, we're gonna be flooded with mass trauma.

We need all the help we can get.

There was a pipeline explosion. He's still not answering.

It's gonna be okay.

Yeah.

Meredith: So, the committee at the FDA

said the first step toward getting approval is,

we have to prove that the cells can survive at every stage.

They need to make it through the reprogramming process,

differentiation, suspension prep, and cryopreservation

without turning into cancerous cells.

So we've succeeded in the cell maturation process.

-I've succeeded at that. -Well, you have,

which is a milestone in itself, but now we need to prove

that the cells can survive once they've been injected

into the brain.Ready here.

You're putting my precious biopsied cells

into a fake brain.

It's a 3D-printed hydrogel brain.

Injecting Trial 1 now.

We're using test cells, and we dyed them blue

to visualize their behavior once injected.

Crap."Crap"?

If the cells stay in a blob, they'll die.

Very scientific. How do we fix it?

We need to try different injection techniques.

Okay. How many of these gel brains do we have?

A-And how much do they cost?

Man: Oh, there's plenty.

And think of it as a contribution

for, uh, you know, science. It's a...

Meredith: You made it.

Uh, bad time?

Woman on P.A.: Dr. Lynne McDonald to the nurses' station.

Dr. Lynne McDonald to the nurses' station.

[ Rumbling, high-pitched ringing ]

Sacilotto: Dr. Hunt?

Doctor? Dr. Hunt!

Corporal Sacilotto, what's the sit-rep

in the ambulance bay?Still clear --

other than a few firefighters with minor injuries, sir.

Copy that. Stay ready.

Hey. Have you seen your sister?

I have looked in all the triage areas.

Her name's not on the surgical schedule,

and she's not in radiology and --Have you tried calling her?

Yeah, but she hasn't picked up. I'm worried.

I mean, there was an explosion, and she took off running.

And with her history --Teddy, she's fine.

-Are you? -I'm fine. Megan's fine.

Everybody's fine, except for the people

who were injured by that bomb.

O-Owen, there wasn't a bomb. It was a --

Listen. They're gonna need our help.

I need to do my job, so why aren't you doing yours?

Um, Hayes? What is she doing here?

Megan: Is he okay? There was an explosion. Was he awake?

He was already under when the explosion happened.

What are you...doing?

Okay. You can start now.

Dr. Hunt, all due respect,

I don't think this is a good idea.

All due respect, I don't care.

Hayes: Megan, we've got this.

Great. Then start.

Look, I'm not leaving my son,

so unless you want his already-failing heart to worsen

because his pericardium is crushing his heart

as we speak, I suggest you start.

Scalpel.

How we doing? I thought it'd be busier.

Yeah, it sounds like most patients are either dead

or at Seattle Pres.

I'm sure Ben is --

Thanks for jumping in, Wilson, but you can

head back up to O.B.

An exploding pipeline isn't exactly joyful.

Bailey, I w--Got -- I got it. Go.

32-year-old female firefighter.

Status post-electrocution -- G.C.S. 15, stable vitals.

Hughes!
