NCIS

Look, I'm telling you guys,

Deputy Director Laroche is dirty.

It's time you know the truth.

He was a double agent working for SecDef this entire time.

Olivia Garcia... she's an old girlfriend of mine.

My name is Mateo. I'm 18 years old.

Why didn't you tell me I had a son?

I know. And I'm sorry.

I would like to be a part of Mateo's life.

You didn't give up your life for nothing,

dear boy, you saved your agency.

To Leon.

All right, order for Stephen with a P-H,

Jenn with two Ns, and

sadly, just Mike.

Here you go.

Oh. It's a capital morning

at Capitol Oaks Coffee. How may I help you?

Mobile order for Kayla.

- With a "K." - Coming right up.

Sorry. He's got a strong arm.

Here you go, cutie.

Aw, it's...

Oh, he sees your badge.

Thinks you're a superhero.

Oh, smart kid. What's his name?

- Evan. - Well, Evan.

You can be a superhero, too.

- Sound good? - Thanks.

- You're welcome. - Order for Kayla with a "K."

Have a capital day.

Duty calls.

See you around, Evan.

Bye.

You couldn't text, Director?

I'm calling as Dad.

We still on for dinner?

Well...

it depends. Who's picking?

I am.

In that case, I'm busy.

Kayla.

Kayla!

Started without me.

You're still having trouble sleeping?

- I'm fine. - It's been a month.

You barely walked away from a suicide bombing.

Other people didn't.

Well, maybe this will help.

The FBI and ATF just closed the case.

And their conclusion?

A disturbed kid with a bomb in his backpack.

A lone wolf.

- Lone? - Yes.

I read the ATF report.

That bomb was sophisticated. Professional.

It had parts you can't just buy at Home Depot.

This wasn't just some kid googling at 3:00 a.m.

This was training. Or guidance.

- Or both. - Now...

- you're making assumptions. - No. They are.

They missed something.

Just like I did.

Kayla.

It's not your fault.

Sometimes agents don't see everything.

If the FBI misreads this bombing,

they'll misread the next one.

What if this wasn't a one-off?

Kayla.

What do you want?

I want to do everything I can

to make sure it never happens again.

MPD says the vehicle belongs to Navy Petty Officer Victor Lee.

Worked at the Naval Research Lab.

Pretty sure this man was carrying the explosive.

Extensive damage to the torso.

A piece of fabric fused to his shoulder.

Looks like it could be remnants of a bag or a backpack.

Young man. Backpack bomb. Sounds familiar.

Coffee shop bombing from last year.

Yeah, and FBI thought that was a lone wolf.

Well, maybe the lone wolf had some friends.

Careless ones 'cause unless their target was an empty alley,

I'd say the device went off early.

Then what was the real target?

Phone and laptop aren't gonna help.

Is that Mateo?

Ah, you guys are getting thick as thieves.

Yeah, we've been bonding lately.

So what is it? Baseball? Laser tag?

- Geohash. - Oh.

I am so afraid to ask.

Geohash is a form of coding. Latitude

and longitude compressed. I'll tell you what, this kid

got some pretty amazing computer skills.

Hmm. Who could've guessed that?

Even told him about the internship program, you know,

in NCIS Cyber, so Mateo's gonna come by tomorrow, take a tour.

That's a big step.

But it's just a tour. You know?

Don't know for sure that it's gonna happen.

We got a Navy bomber to deal with here.

Negative on the Navy part.

Petty Officer Lee is alive and well.

Currently holding Warrior Two

in a hot yoga class two blocks over.

If our bomber isn't Navy, who is he?

Got one wallet here. Extra crispy.

Ryan or Bryan Wallace. 19.

Organ donor.

I'd say the ship has sailed on that one.

Oh, Ryan Wallace.

Lives in Reston.

Uh, registered vehicle's a blue Honda.

You mean like that one?

Oh. Uh, yeah, could be.

Be careful.

Maybe our bomber left behind something useful,

like info on his actual target.

Targets. Plural.

Better clear the area. Get the bomb squad back in here.

I don't think those backpacks are filled with school supplies.

I found a manufacturing defect.

This capacitor was cracked before the explosion,

causing the premature detonation in the alley.

Mm, bad luck for the bomber.

Very good luck for everyone else.

Because the other six devices... all fully functional.

If he had made it to his targets...

We would be counting dozens of bodies, not just his.

I confirmed our bomber's DNA... Ryan Wallace.

- 19. Single. No next of kin. - Device data?

Laptop and phone were completely destroyed in the blast.

Apartment was basically a mattress and a router.

All we've got are the contents of his car.

Trash, receipts, and this.

Agnors Bliss.

It's a sci-fi space opera that's a little too niche, even for me,

and I read the Dune glossary.

So we've got nothing?

Not nothing. Keep walking.

I compared all of the alley bombs

to last year's coffee shop device.

Same parts. Same soldering technique.

Same assembly sequence.

That's not a coincidence.

Oh, no. That's a signature.

Someone's training people to build these.

So it's not one bomber, it's a network.

Which means we need to reopen the FBI's coffee shop case.

Figure out what got missed.

I already pulled the original witness list,

and look who's on it.

The director's daughter was there?

Mm, according to this, she stepped outside

just before the blast.

- And we never heard about it? - Oh, Vance and Kayla probably wanted

to avoid the media attention.

Haven't seen her since his funeral.

I heard she took personal leave.

Okay, so maybe we don't make Kayla relive

the day that almost killed her.

There are plenty of others to start with.

Maybe they can help.

The FBI was wrong about that coffee shop.

They called my son a lone wolf. My Danny

detonated that bomb... I'm not denying that...

but he didn't do it on his own.

NCIS agrees, Mr. Hammersmith.

Uh, call me Hank.

Listen, Hank, we are investigating

a second backpack bombing. We believe

that it may be connected to the one from last year.

I knew it wasn't just Danny.

Well, these are the items that we recovered...

from the latest bomber.

Does anything look familiar?

Anything connect to your son?

None of this rings a bell.

Danny...

kept things to himself.

His whole life was online.

He talked about chatting with friends,

but I never bothered to check in.

Told myself it was just a phase.

The mood swings, the anger, him

pulling away from family.

Whatever was going on with my son, I missed it.

It's hard to know what's going on in any teenager's head.

But I could have asked.

Don't let me keep you.

Oh. It's, uh, it's actually my son.

Just checked in for an internship tour.

That's good.

Stay close.

If family doesn't fill the space...

...someone else will.

Like these, uh, "friends" your son met online?

Yeah. On that website Archive.
