Dispatch, 1-4 on scene. Possible trespass in progress.

1-4 copy. Will notify.

What do you see, rookie?

Not much, Sarge.

Looks empty.

Maybe just a false alarm?

Maybe. But we should take a closer look.

Trust me. Take 30 seconds now,

save three hours later.

Ooh.

Do they always smell so bad?

Come on, rook, this here's a four-star alleyway.

Urine-free. Not a rat in sight.

Mm. Oh, God!

Guess you found our trespasser.

Is he...

dead?

Sure smells it.

Check his pulse.

I'll call it in.

Turn off the light, please.

Did he just talk?

Yes.

And I said turn off the light.

- Trying to sleep here. - Aw, for real?

- Another drunk sailor? - What do you expect?

The entire Second Fleet is anchored just offshore.

We're being invaded.

Oh, yeah. Let's go!

Hey, stop! Police!

Tell me, rook, do we ever leave the keys in the car?

No, ma'am.

It's our top priority, Chief. We got a BOLO out

on your stolen squad car. When we find it,

these sailors are looking at serious charges.

Yeah. Yeah, tell me about it.

Last year's Fleet Week was a cakewalk compared to this one.

It's like there's something in the water.

Look, Chief, I got to go.

Okay, please tell me this isn't your work.

Oh, no. No, they did this to one another.

Early-morning bar fight.

Typical NCIS. Always riding us.

Give us a break, man. We've been at sea for months.

We're just trying to have a good time.

They almost killed each other.

Not even close.

You know, you guys are total fun police.

What'd I tell you about calling us that, man?

Okay, okay, okay. Just get 'em to the garage.

We're holding everybody there till their commands

can pick them up. Go.

- Let's go. - Lead the way, fun police.

Yeah, no, no, no. Uh, understood.

We'll, uh, we'll do our best.

McGee, MPD needs an update on their stolen squad car.

Yes, uh... I had Kasie pull up its GPS,

but, unfortunately, it is malfunctioning.

Tell you what, though... least it has GPS.

'Cause you know what doesn't? Goats.

- Goats? - Yeah.

Goats. Eyewitnesses saw a sailor

release them from an enclosure on the National Mall.

Now I get to put out a BOLO.

Why are there goats on the Mall?

Nature's lawn mowers, man.

National Park Service uses them to cut the grass

without using gas.

Actually right.

Can we help you?

- Oh, it's... - Oh, no, no, no.

He's with me. He's mine.

Sorry, sorry.

I told you to stay with me.

- I'm sorry, pretty lady. - Mm.

Found him doing pull-ups in a cherry blossom tree.

Mm. Why is he wearing a banner?

Because that's all he's wearing, Tim.

- Oops. - Ooh.

Oh! Okay.

So, let's... yeah, let's just keep this... okay.

Let's just keep that on.

Can we get him some clothes, please?

Paulson, can, uh, you take this sailor

down to autopsy and have Jimmy give him a fresh pair of scrubs?

Yeah, maybe some munchies, too?

- No, it's okay. You can go. - Come on, champ.

This way. That's it.

Is it me or is Fleet Week crazy this year?

Yeah, and it feels really wrong.

I mean, everybody's out here celebrating,

meanwhile in here, we're still...

Yeah. Well, we went straight from Director Vance's funeral

last week to the chaos of Fleet Week.

It's like we haven't had the chance

to process anything.

Well, the world moves on.

DoD just sent another memo.

They want Vance's office cleared out by Friday.

In the middle of Fleet Week?

What's the rush? Interim director

hasn't even set foot in the building.

Well, don't get too attached.

We'll probably get five more just like him

before they settle on someone.

We'll just have to find the time.

Or not.

Oh, my phone's dead. What's it say?

The BOLO came back on the stolen squad car.

Sailors abandoned it across the river.

Oh, wow.

Yeah, MPD is not gonna be too happy.

Ooh.

How the hell

did they even do this?

I mean, look at these parked cars.

There's not a scratch on them.

Well, maybe they parked there after the crash.

And who parks next to a crashed police car?

Eh, it's pretty hard to find a spot in this part of town.

Hey, Tim, tell me you found a security camera.

We need to see how this happened.

Well, the café doesn't have any, so we still have

no idea on the sailors who did this.

Well, maybe I can pull some fingerprints

from the inside of the car.

- Yeah, I'll take some photos. - All right.

So, how'd the, uh, MPD chief take the news?

Better than I thought. I think Fleet Week is wearing him down.

Can't say I blame him.

You know, of all my Fleet Weeks,

I've never seen anything like this.

I got to say, could've been a lot worse.

At least nobody got hurt.

Found a key fob.

You were saying?

The body in the trunk belongs to Petty Officer

Third Class Kyle Rivas, he was a machinist's mate

aboard the USS Allegiance.

They docked in Baltimore for Fleet Week.

Well, half the guys we picked up this week

were from the Allegiance.

Hey. Do we know that guy?

Is that Joey Deets?

What are they doing up here?

Uh, the restrooms downstairs are out of order,

so we're allowing them to use the facilities on this level.

- Great. - Just ignore them.

According to our victim's XO,

Rivas was a dedicated sailor

with a perfect service record.

Not the type to steal a police car.

Well, except that it looks like he did.

Or at least, went along for the ride.

Fingerprints were all over the passenger seat.

Who was driving?

Seaman Daniel Harvey.

We found his fingerprints

on the steering wheel.

Shipmates say that Harvey and Rivas

were best friends, and that they were even liberty buddies

during Fleet Week.

Aren't liberty buddies supposed

to keep each other out of trouble?

We also found Harvey's prints on the murder weapon.

Oh, damn.

- Joey Deets is dead? - Can somebody please

get these guys out of here?

Still got to use the bathroom.

Not cool, fun police.

- Okay, I'm gonna hit him. - All right, all right.

Hey, hey, hey.

All right, where is our missing car thief now?

Uh, AWOL for the past 12 hours.

We have a BOLO out on him.

These guys are from the same town,

they joined the Navy together, they're best friends.

What the hell happened last night?

They met a girl.

Got Rivas's phone here.

Battery was dead so I had to charge it.

Look at the last photo that was taken.

Now, time stamp says that it was taken

after they stole the squad car,

but only an hour before Rivas's time of death.

She's probably the last person to see Rivas alive.

We need to find her.

It's just disrespectful.

We're not the fun police,

we're the "keeping you safe" police.

Why don't they get that?

Oh, come on, Nick.

Sailors have been calling us this for years.

It's nothing new.

Eh, it's just different now.

You mean, after Vance?

Yeah, I get that.

Vance sacrificed everything so we could keep doing this job.

Hurts to hear them trivialize what we do.

Yeah. It's also not very clever, you know?

"Fun police"?

No. We can do better than that.

Ahoy, there.

Can I help you?

Oh.

Do you like it?

I'm trying on my costume for our Fleet Week Social.

Just don't call it a party.

Do you guys know about Fleet Week?

Yeah, we've heard of it. NCIS.

And you are?

Samantha Barnes.

TAG House president.

What's this about?

We're looking for this woman.

We believe she may be a member of your sorority.

Oh, yeah, yeah, that's Annie.

Annie Carson. Let me guess.

Did she break one of these sailors' hearts?

Stabbed to death?

That's awful.

I-I don't know how I can help.

I only spent a few minutes with them.

- How did you meet? - At the bar.

It's usually quiet, and I go there to study.

But last night, it was packed with sailors.

They were nice, just...

a little too drunk for my liking, so I left.

Can anyone confirm what time you got home last night?

I can.

This is Annie's digital check-in.

She got home at 10:20 p.m.,

like the responsible TAG sister she is.

That's 30 minutes before Rivas was killed.

Did they say what their plans were

or where they were going?

We really didn't talk much.

The two of them were arguing, a lot.

About what?

Um, well, it sounds kind of weird,

but they were arguing about "nukes."

Nukes? Like nuclear weapons?

I don't know.

- I hope not. - Oh, honey.

Nuclear weapons? Murder?

What a night you've had.

But don't worry. I know just what you need.

TAG House Hug!

Why would two junior enlisted sailors

be arguing about nuclear weapons?

Well, why don't we ask Daniel Harvey?

Police picked him up, and you'll never guess where.

Seaman Daniel Harvey.

So, how was, uh, the Lincoln Memorial?

Inspiring.

Until the cops slammed me to the ground

and brought me here.

Didn't know it was a crime to go sightseeing.

Well, it's not, but, uh, going AWOL is.

Failed to report to your command last night.

Me and half the fleet.

Why do I get the special treatment?

Is this an act

or does he really not know why he's here?

What do you remember from last night, Danny?

Do you remember stealing a cop car?

What?

No.

Remember crashing

that cop car?

I don't know, I...

Maybe I had a little too much to drink?

I must have blacked out.

Oh, Kyle.

Petty Officer Kyle Rivas.

A-Ask him.

He'll vouch for me.

That's gonna be a problem, Danny.

We found Kyle's body in the trunk

of that crashed cop car.

And we found your

fingerprints on that knife.

No.

No, no, Kyle was my best friend. I would never hurt him.

We've been through everything together.

Except that was about to change.

We have a witness who said you two

were arguing last night about "nukes."

But we know you weren't talking about nuclear weapons.

Navy Nukes are the people that work on nuclear propulsion.

We found a transfer order in Rivas's file.

He wasn't coming back to the ship with you

after Fleet Week, was he?

Before we went out last night,

he told me he'd applied to be a Nuke.

He said he was going to the Naval Nuclear Power School

in South Carolina.

Uh, your best friend was about to leave you.

I'd be pretty angry, too.

Danny, if you can't remember

stealing a cop car,

then maybe you can't remember killing your buddy, either.

Truth is starting to sink in.

I almost feel sorry for him.

- Hey. - What's up?

I just got the toxicology report

for Seaman Harvey and our victim Rivas.

Okay, how drunk were they?

That's the thing. They weren't.

Yeah, they had alcohol in their system,

but not enough to make them black out

or stupid enough to steal a cop car.

Yeah, it doesn't seem like Danny's lying.

Oh, I don't think he is.

Something messed with his head, and it wasn't the alcohol.

I found a toxin in both of their systems.

He and Rivas were poisoned.

Could that cause him to black out?

Oh, we're lucky if that's all it did.

Any healthy immune system

is gonna fight that toxin tooth and nail.

We're talking dangerous allergic reactions, vomiting,

anaphylaxis.

What about hives?

We need to get Jimmy up here right away.

Hey, Jimmy,

we need you to... what?

Wait, hold on. Slow down.

Slow down. I'll be right there.

It's getting worse.

When the ambulance gets here,

this one's priority.

Hey, Jimmy, what's going on?

I don't know.

They started complaining about, uh, nausea,

dizziness, hives, and then they just started collapsing.

Dr. Palmer!

Oh, it's the same symptom.

Hey, how many are getting sick?

All of them.

Okay, breathe in.

And breathe out.

All right. Sounding much better, Danny.

Let's see. Your hives are already starting to clear up.

You can take him back to interrogation now.

So, he's the last of them?

Yeah. All stable, thankfully.

Things could have been a lot worse

if Kasie hadn't traced all their symptoms

back to that toxin.

Left untreated, we're talking

organ failure, even death.

What the hell is this toxin?

Uh, Kasie's still researching it now,

but initial symptoms seem to mimic the high

one gets from amphetamines.

Amphetamines?

So, it's like a drug?

Does that mean that they took it willingly?

I don't think so.

None of the sailors in that file over there

have any record of drug use.

Plus, recreational drugs

wouldn't trigger an immune storm 12 hours later.

No, this wasn't designed for fun.

This was designed to harm.

It does explain the sudden uptick in "Sailors Gone Wild."

You think the toxin is the reason that Fleet Week

has been so crazy?

Yeah, it gives its victims one hell of a high.

Could that also explain why Danny stole a cop car

and stabbed his best friend?

Eh, it's possible, there's still so much about this toxin

that we don't know yet.

If we knew what all these sailors had in common,

that may tell us how they were exposed.

Except I need answers now.

I've got the vice admiral of the Second Fleet

waiting for me upstairs.

I need to tell him something concrete.

Okay, uh, in that case...

Agent Parker, it is my medical opinion

that someone is deliberately poisoning

U.S. Navy service members.

I just can't prove it yet.

Find out what they all have in common.

Yeah.

Sorry.

Looking for an outlet. Phone died.

Busy day.

Uh, Special Agent Alden Parker.

Are you, uh, with the vice admiral?

Yes, but I'm afraid he couldn't make it.

Cooper Ellis, Second Fleet STRATCOM advisor.

Are we waiting on the director?

Well, we would be, but I don't think the interim director

is going to be as hands-on as his predecessor.

Of course.

And my condolences on your loss.

I hear Director Vance was an impressive man.

That he was.

I assume this is regarding the murder?

Petty Officer Rivas? Have you made an arrest?

We have. Seaman Daniel Harvey, a liberty buddy.

Another sailor. That's unfortunate.

From a communications standpoint.

The message of Fleet Week

is "Strength through Brotherhood."

Well, then, you're gonna love this next part.

Uh, we believe that service members are being poisoned.

At least a dozen so far.

That's terrible. Are they okay?

They're all recovering, but only because

they were treated quickly.

So, for everyone's safety,

I think it's best that all Fleet Week sailors

return to their commands.

I take it we're not talking about

a bad case of food poisoning?

No. We believe that there is someone

trying to harm these service members.

Do you have a lead on who? Or why?

We're working on it.

Do you know how these sailors were poisoned?

We're working on that, too.

Agent Parker, I'm beginning to suspect

that this meeting was a bit premature.

We're just trying to get ahead of the situation.

As a, as a PR rep, Mr. Ellis,

I'm sure you can appreciate that.

Strategic communications advisor.

Little different.

Of course.

- I didn't... - Thank you for briefing me

on this, Agent Parker.

I'll be sure to brief the admiral.

And it will be brief.

But for now, I suggest you just keep "working on it."

The moment you have something actionable,

you know how to reach me.

You made it look easy, Leon.

Oh. What is this?

Another line for the bathroom?

No, this is just me

trying to figure out what all these sailors have in common.

Well, join the club. We got nothing.

Yeah. They all come from different ships,

hit up different parts of town last night.

Yeah, they were eating at different restaurants

and drinking at different bars.

Yeah, we did a deep dive and we came up with nothing.

You guys, the answer was right in front of our eyes.

And under their clothes.

- Come again? - So, when I was examining these sailors,

I got to see them all with their shirts off.

Guess what they all have in common.

- Chiseled abs? - What?

No. No.

No, no, no. They-they all have brand-new tattoos.

Uh, excuse me, everyone, can you please,

uh, show us your tattoos?

Oh, okay... uh, no, sir.

No. Thank you. We will take your word for that.

Okay. All-all right, everyone, that'll do. Uh...

As you were.

Okay, the point is,

all these sailors had fresh ink within the last 24 hours.

I mean, even our victim Rivas had a brand-new tattoo.

Well, getting a tattoo is a shore-leave tradition.

Exactly.

So, if you wanted to secretly inject a toxin

to a bunch of sailors,

a tattoo would be the perfect delivery mechanism.

How can we confirm it?

Well, you got to take a lot of samples.

But if the tattoos are the source of the toxin...

Then we need to find out where all these sailors got inked.

Okay, just hold still.

Wait. Have you done this before?

Have I ever biopsied a tattoo to see if the ink was toxic?

- No. - Seriously? I don't know if I'm comfortable...

And I'm done.

Thank God for local anesthetic.

So, since none of our sailors

can remember where they got their tattoos,

I've uploaded all of their phone location histories

to see where their paths line up.

They were all over the map. There's no overlap.

Except for the National Mall.

Right, but no tattoo parlors there.

Just museums and goats.

Except now there are no goats there, as well.

Still no hit on the goat BOLO?

No. There's a few reported sightings,

but nothing panned out.

No, I think those, uh, goats are now ghosts.

Yeah, and so is our tattoo parlor.

You interviewed everyone?

Yeah. Everyone, uh, except for him.

Seaman Harvey,

have a seat and please show me your tattoo.

Hey, Danny.

You feeling better?

Sure.

Great.

Listen, um,

we're trying to find out where you got this tattoo,

because we think whoever gave it to you,

uh, probably put some toxin in the ink.

And you think that's what made me kill Kyle?

Uh, we're still investigating.

Save yourself the trouble.

Even if I was

out of my mind when I killed him,

it doesn't matter.

My best friend is dead,

and nothing you say or do is...

...gonna bring him back.

You're right. Your friend's not coming back.

He's gone.

But you're still here.

So, you have the opportunity to try to help other sailors

who might be exposed to this toxin.

And I think that Kyle would want that.

Don't you?

Okay.

It smelled of exhaust.

What did?

The tattoo place.

Like a running car.

Maybe it was near a freeway?

It was small, too.

The ceiling was low. I had to bend down to walk.

Maybe the parlor wasn't near cars,

maybe it was a car.

A mobile parlor.

That's why there was no overlap on their location histories.

Because they all got their tattoos in different places.

From the same mobile tattoo parlor.

Do you remember anything else?

There were teeth.

Hey, you two.

Get back to the ship.

You really don't want

to get a tattoo from there.

Back up.

NCIS. We got a warrant.

Open up or we're coming in.

Back.

Ready?

Well, that's our tattoo artist.

Looks like his killer was searching for something.

Yeah, my money's on that toxic ink.

I think he found it,

but left us something.

A stab wound.

And a fresh tattoo.

That was done in a hurry.

The killer's sending a message.

In Russian.

Our dead tattoo artist

is Gideon Mays,

the sole owner of the Dragon Wagon mobile tattoo parlor.

Where all the sailors got inked.

We found photos of their tattoos in Mays's phone.

He was offering a Fleet Week special on social media.

Free tattoos for all sailors.

That deal is way too good not to have a catch.

A catch like getting inked by a toxin?

Yeah. Kasie confirmed that the tattoos were the source.

So, this guy was luring U.S. sailors

to his tattoo parlor in order to poison them.

But he actually wasn't doing it for free.

Somebody paid him.

Five days ago, Mays only had $604.52 in his bank account.

But then, on the first day of Fleet Week,

he got a deposit of $50,000 from an offshore account.

And I have an idea of how far offshore.

Take a look at this.

Well, according to Jimmy, this tattoo was inked

after the tattoo artist was stabbed to death.

The word is Russian for "purge."

It's also the calling card for this group,

- Pale Sun Brigade. - I've heard of them.

State Department considers them a terrorist organization.

Well, in Russia, they've been responsible for shootings

and bombings against ethnic and religious minorities.

They want to purge the world

of anyone who is not them.

But why purge the tattoo artist if he's working for them?

Well, Pale Sun Brigade has been known

to posthumously ink traitors,

so maybe Mays tried to double-cross them?

What about the toxic ink? Was it still in the van?

Gone. We think the killers took it.

Which means there's nothing stopping them

from doing this to more people.

Agent Parker, we are mere hours away

from the Fleet Week closing ceremonies.

People are already gathering to watch the fireworks.

What exactly do you want me to do?

Shut it down. All of it.

Because of tattoos that made some sailors sick?

Because we believe a terrorist organization

is targeting the U.S. Navy,

and you are organizing a U.S. Navy event.

Maybe these terrorists

are just trying to scare us into canceling the ceremony.

Have you thought of that?

We could be playing right into their hands.

You asked for something actionable, Mr. Ellis.

We have two dead bodies and a direct threat.

You're the strategic advisor. Do your job.

Advise the admiral: shut it down!

Excuse me. What are you doing?

Is this from the director's office?

Who told you to do this?

No, Parker, it's okay.

Uh, they're not taking anything

out of Vance's office.

Those are files that are being returned from CID.

Oh.

Sorry. Just... carry on.

Hey.

- Uh... - You okay?

Yeah. I...

I don't know how I am.

I haven't had a second to think about it.

I understand that.

I should be an expert

in handling loss after this last year.

I'm not sure that's how it works.

Did you have something?

Yes, and it's actually good news for Danny.

Really? The guy just lost his best friend.

Yeah, but whoever killed Rivas also killed the tattoo artist.

Jimmy says the wound profiles are exactly the same,

meaning that the same knife was used in both murders.

But how is that good news for Danny?

It sounds like he killed them both.

Except he didn't kill either one.

He couldn't have.

Jimmy puts the tattoo artist's time of death at 9:30 p.m.

- At that same time... - Danny was across town,

stealing a cop car.

Exactly. He's innocent.

Yeah, but why would a Russian terror group

kill the tattoo artist, and then track down

and murder a random sailor?

That is a good question.

We're still missing a big piece of the puzzle.

Yeah, the Russian terrorists.

Has Kasie been able to find anything

in the, uh, the Dragon Wagon

that might help us track them down?

Unfortunately, she's been having some...

technical difficulties.

Nothing is working.

Mass Spec keeps giving me error messages,

my modem won't get any signal

and my cell phone battery keeps dying.

Wow, Kasie, that's a lot.

Maybe it's time to get some new equipment.

Don't say that. Okay, because this software upgrade

was the last thing that Director Vance...

...approved for me.

God, I know that sounds stupid.

No.

It doesn't.

We all honor him in different ways, Kasie.

Oh, I, um...

I did manage to get one result from Mass Spec

before it conked out, but even that doesn't make any sense.

Okay. Show me.

Okay, well, I finally managed to ID the toxin

as a phenylethylamine substitute.

Very weird stuff.

But not as weird as what I found in the tattoo ink.

This ink is made with a chemical suspension

that simply shouldn't exist.

Oh, come on, don't tell me it's aliens again.

No. No.

But whoever could design this suspension is a genius.

I mean, they made the theoretical possible.

What's that?

Grad school thesis paper.

It's the only research I found that outlines a method

for creating the suspension.

Huh. We might want to talk to the author.

Actually, we already have.

Yes, I wrote this,

but it was rejected

by the chemistry department last year.

Then how'd it get online?

I may have... posted it.

They were wrong to reject it. It's good science.

The chemical suspension is viable.

We know. We found it.

In the blood work of the sailors you met two nights ago.

And inside that chemical suspension, we found a toxin.

A dozen Navy service members

were poisoned by your invention.

No. I didn't do that.

- You didn't invent it? - No, I did,

but I didn't poison them.

Then who did?

You don't want to tell us,

then maybe your bank records will.

Over the past six months, you were paid $200,000

from an offshore account.

Goodbye, student loans...

Hello, Russian terrorists.

Those are your employers, right?

Not only yours. We believe that they paid

a tattoo artist

to inject these sailors with your toxin.

Annie, you need to tell us how we can find

these Russians.

Okay, see, the problem is, I can't talk about this.

I signed an NDA.

With the terrorists?

No.

I mean, I really hope not. I...

I thought they were a legit company.

Who?

Okay, Annie.

Two people are dead.

You really want to go to prison over an NDA?

Okay, yes.

This company paid me to synthesize the suspension.

But they also paid me

to test a "mystery additive."

I did, it worked and I never heard from them again.

Did you know that this additive was a toxin?

No. You've got it wrong.

The additive isn't a toxin.

The suspension itself is toxic.

That's why it shouldn't be in the human body.

And I warned the company about this,

but clearly they didn't listen, because two nights ago,

I got an alert that the additive was walking around D.C.

Excuse me?

I tracked it to this bar.

What do you mean, you tracked it? How?

I shouldn't have said that.

I'm sorry, I think I need a lawyer now.

I really can't afford to get sued.

I think Annie is telling the truth.

- Which part? - About the additive.

It's not a toxin. Okay.

I couldn't get Mass Spec to analyze the tattoo ink,

so I put it under a microscope, and this is what I saw.

The "additive" is nanorobotics.

Essentially, microscopic machines.

Are you saying that all of these sailors

have tiny machines inside of them?

Doing what?

Transmitting their location. We were wrong.

The tattoos weren't designed to poison the sailors.

That was an unintended side effect.

The tattoos were designed to track them.

So, this isn't terrorism.

This is espionage.

Someone is spying on the U.S. Navy.

Okay, so, all of the sailors' tattoos,

or rather, the nano-trackers inside of them,

work essentially like liquid Bluetooth trackers.

You know, the kind that you drop in your luggage.

Right, it transmits a signal

so you can follow it wherever it goes.

That's how Annie tracked the sailors to the bar.

Yes, and like the Bluetooth trackers,

the nanotech can't transmit very far on its own.

It needs to piggyback on a more powerful device.

Like our phones.

The sailors' tattoos are the reason

that our cellular phones keep dying.

The-the constant signal is draining them.

Yeah, and that signal is why Mass Spec

keeps giving me error messages.

Too much interference.

Can we access this signal

to find out who's tracking these sailors?

Well, so far, we've only been able to track

who's been transmitting, namely, the sailors with tattoos.

But with Annie's help, I might be able to hack the signal

and figure out who's tracking them.

What about the ink itself?

We didn't find any at the tattoo parlor,

but shouldn't that be transmitting?

Theoretically, yes, but if it's not near any phones...

- Or if it's in a Faraday cage... - Then we can't track it.

No, the bigger concern here is why are terrorists

tracking U.S. Navy sailors?

Well, this is military-grade technology.

How much you want to bet the Pale Sun Brigade

is working for the Russians?

Russian technology in American service members?

I don't like the sound of that.

I like the sound of that, though.

I found an embedded ID number

in the nano-trackers, ran a search.

- That's weird. - What?

It's not Russian technology. It's ours.

Agent Parker. I did what you asked.

The Fleet Week ceremony is canceled,

and I have a communications nightmare on my hands.

What is so urgent that you needed to see me?

Well, I was hoping you could clear up something for us

before we, uh, hop on a call with the Secretary of Defense.

SECDEF?

What's this about?

You recognize that?

It's a patent for nano-trackers.

You filed it on behalf of the Defense Advanced

Research Projects Agency two years ago.

True, I worked for DARPA, but we parted ways.

Actually, uh, you were fired for cutting corners.

So what?

Aren't you supposed to be chasing down Russian terrorists?

We were.

And we thought we chased them to this offshore account.

But when our warrant came through,

we discovered it belonged to you.

You used it to pay Annie Carson to find out how to incorporate

these nano-trackers into the human body.

And the way we look at it,

there are two possible explanations here.

Either you are working with some sort

of off-book DoD operation...

Or more likely, you, uh, stole the trackers

on the way out the door, and now you're trying

to sell them to the Russians.

I am not a traitor.

Sir, we have connection.

SECDEF's ready.

Well, I guess we're gonna find out.

Put him up on the screen.

Wait, wait! Stop.

Yes, I stole the nanotech.

But I did it for our country.

I was always going to give it back to DARPA.

I just needed to show them that the tech was viable.

And Fleet Week was the perfect proving ground.

You had hundreds of sailors all looking to get tattoos.

You used them as unwitting test subjects.

How do you justify that?

Because we've done it before.

MKUltra?

The Edgewood/Aberdeen experiments?

Come on, Agent Parker.

What's a few sick sailors in the name of national security?

"National security."

I think you just wanted your old job back.

But hey, whatever helps you sleep at night.

Sure hope you still have the rest

- of that ink. - It's safe.

I picked it up from Mays a few days ago.

I don't know how the Russians got involved,

but I didn't involve them.

- Then who did? - I don't know.

I don't know.

Annie was the only other person who knew about the nanotech.

No, someone else does, too.

Kasie detected a ping on the nanotech signal.

Someone's still tracking the sailors.

Or they're tracking the ink.

I mean, if he's telling the truth...

I am telling the truth.

...and the Russians don't have the ink,

that means they're still trying to get it.

That's why they targeted the tattoo artist.

They were looking for the ink.

Yeah, except Ellis here had already taken it back.

Yeah. Russia pivoted, started looking

for sailors who had the ink

- in their bodies. - Yeah. Like Kyle Rivas.

You realize that this means anyone with a tattoo

- is a possible target. - Okay,

are you sure that we got them all?

♪ ♪

Hey, Sailor. What's your name?

Special Agent Nick Torres.

But you can call me Nick, Samantha.

I'm so sorry. I thought you were a sailor.

Yeah, well, were you looking for this?

I don't know what that is.

I'm sorry, I have to go check on something in the house.

You're not going anywhere.

Your sister Annie helped us track the nanotech signal

back to a phone at this party.

Your phone, as it turns out.

Okay, well, it's not a party, it's a social.

And this is an arrest. Turn around, please.

- TAG House Hug! - No...

- No, no, no, no. No hugging. - No, no, no, no.

- No, no, no. - No hugging.

It's the fun police. Figures.

I heard that.

Samantha Barnes, you are under arrest

for the murder of Gideon Mays

and Navy Petty Officer Third Class Kyle Rivas.

Fun police! Fun police!

Fun police! Fun police! Fun police!

Fun police! Fun police!

So, the killer was another

- sorority girl? - Mm-hmm, and a nosy one.

Samantha's family is deep in debt,

and they recently cut her off financially.

Yeah, when she found out that her sorority sister

started working on cutting-edge nano-trackers,

she saw her chance to make some money.

So, she hacked into Annie's research

and started tracking their signal,

and when it finally turned on during Fleet Week,

she made her move.

Yeah. Confessed to both murders.

Now, first, she went after the tattoo artist...

- Wasn't that Russian terrorists? - No.

No, no, no, turns out, there were no terrorists.

Samantha was just trying to throw us off her trail.

Apparently, she was a Russian Studies major.

She was always gonna sell those nano-trackers

to the highest bidder on the dark web.

But when she couldn't get the ink from the Dragon Wagon,

she tracked the nearest signal to the National Mall.

That's where she found Petty Officer Rivas.

She stabbed him, and then tried to cut off his tattoo.

She was stopped by a herd of goats.

Wait, did you just say "goats"?

The goats that you were looking for?

Yep. Turns out, Danny actually released them.

Pretty much chased Samantha away.

It is official: Fleet Week is crazy.

Oh, goats are back home, by the way.

A jogger spotted them grazing on Roosevelt Island.

Well, it's nice to know that Fleet Week

- has at least one happy ending. - Mm-hmm.

For Danny, it is a much different story.

I can't thank you enough, Agent Parker.

For finding Kyle's killer.

And clearing my name.

Well, it means you still have a future in the Navy, kid.

Thing is...

...Kyle was always right there with me.

Every step of the way.

How am I supposed to do this without him?

Tell me about Kyle.

What do you want to know?

How'd you two meet?

It's actually kind of a gross story.

Well, now I definitely got to hear it.

It was the first day of second grade.

Lunchtime.

My mom packed me a tuna sandwich and chocolate pudding.

And there was this kid sitting at the table behind me.

♪

Hey, Parker.

Thanks for coming.

I know it's late.

We really doing this?

I mean, can it wait?

- I just don't know if I'm ready. - And...

it'll be a little hard to pack things up without any boxes.

That's not why I called you here.

What's this?

Well, this is a little something

Vance had in his desk for a special occasion.

Come on. Everybody, grab a glass.

I didn't forget you, Nick.

There's an extra glass.

Yes.

Yeah, there is.

This, uh, this last couple weeks...

...been nonstop,

you know, one thing after the other.

It just seems like the world would like nothing more

than just, just to...

...move on.

You know? And...

...to forget.

But the only way I know how to get through this

is by remembering him.

And there's no one I would rather...

...remember him with

than all of you guys.

So...

...to Leon.
