Glad to see the vest still fits.
Max busted me to level one, so I'm here

Anything else I can do, let me know.
How about you do what I ask.
I just want to earn back what we lost.
It's not your trigonometry

It's my judgement.
CHAVEZ: Robert Cuevas worked
in this factory the last eight years.
You didn't kill him, did you?
JACK: This robot
hit our victim on the head.
Very hard.
Cliff.
Very hard.
Cliff.
Robert wasn't even supposed to be

Cliff?
Maybe the brakes were out.
We're not thinking the AI somehow did this, are we?
BEAU: Old camera.
Can't wait to see what's on that film.
If there were any film in here, it's long gone.
I just know this case was weighing on you.
Hope you rest a little easier now that it's closed.
ROBY: For now, you stay put.
Drive safe, stud.
Call me next time you're in town.
Yep. See you around.
No tip? Cheapskate.
Hey.
Hey! You dropped something!
You're still here?
Your shift ended four hours ago.
Um, I still need a response

about the timecards sign-offs...
I'll get to it, soon as I can. Thank you.

CHAVEZ: So, we've got two victims, a father and son.
Dad was Harry Pallatine.
He sits on a few state committees,
got the key to Henderson once.
Looks like the family's got some money.
CHAVEZ: Yes, indeed.
Now, second victim
was Harry's son Nic.
A junior at Cornell back for spring break.
There's more than two victims.
Don't forget about us.
RAJAN: What happened to him?
The first two EMTs at the scene rendered aid for an hour
before calling it.
When they were waiting for the coroner,
they started feeling sick.
Sick how?
Nausea, vomiting, bleeding.
By the time I got here,
one of them was already unconscious.
Has anyone been inside since?
Nope. We cleared out.
Good luck in there.
Could be a gas leak.
Uh, that might be best case.
Or could be some kind of aerosolized poison was released.
Whatever it is, time for a costume change.
Why don't I stay back here?
You know, interview the EMTs.
Don't be silly.
Yellow looks great on you.
I don't see anything that screams of "gas leak."
I'll check the air.
There's no carbon monoxide.
There's nothing unusual at all, actually.
The air's clean.
CHAVEZ: Whatever it was could've dissipated.
And maybe it was pumped in?
Something airborne dangerous enough to kill two people...
...would... surely would leave something behind.
I don't know any kind of gas that causes you
to bleed from your eyes.
RAJAN: Me neither.
If this wasn't gas, then
what was it?
That's weird.
CHAVEZ: What?
That's weird.
CHAVEZ: What?
FOLSOM: There's some artifacts on the picture. I...
I've never seen that before.
Something wrong with your camera?
I don't think so.
It's not on the screen or the lens.
It must be something that...
It's radiation.
What?
FOLSOM: These spots-- t-they're radiation particles
hitting the camera sensor.
CHAVEZ: Guys?
I think this dude was a nuclear expert.
Do these suits protect us from radiation material?
Uh, we don't have time to find out.
We got to go. We got to go.
Okay. All right, let's move.
Hey.
Where's Allie?
Uh, no, she's still scrubbing.
The longer the hair, the longer the decontamination.
Are you okay?
Yeah. We dodged a bullet.
BEAU: A radioactive bullet.
We did a test with an extended range Geiger-Müller detector.
The radiation dose that you absorbed
was safe for the five minutes you were in there.
Best defense against radiation is limiting the exposure.
You're lucky.
The EMTs were in there for hours.
They said the Pallatines
died from complete circulatory collapse.
That's how radiation kills.
Blood pressure drops, heart stops,
followed by multiple organ failure.
Even if they had gotten to the hospital immediately,
Harry and Nic Pallatine stood no chance.
Okay, we need to figure out what is causing the radiation,
how it got there and who put it there.
I-I got to believe this is about Harry.
He was on the state nuclear committee.
Maybe somebody took him out because of his work.
We need to get back in there.
I called the cavalry.
Who's the cavalry?
Nevada's Department of Radiation Management.
They're gonna monitor the scene
and liaise between state and federal agencies.
Boss.
I, uh...
I would love to be in front on this.
Max...
Max, I can handle this. Please.
Okay.
You got to get back on the horse sometime, huh?
But...
they're the experts,
you're in the sidecar.
Yeah.
Follow their lead.
I don't care how quick, Mike, no one gets anywhere near
this scene without proper protective...
That's my son in there.
You have to let me in.
I need to see my son.
Mrs. Pallatine,
it's too dangerous, I'm sorry.
No, I flew here as soon as I could.
I thought I'd get to see him.
Mrs. Pallatine, I'm Catherine Willows with the crime lab.
We are very sorry for your loss.
Please, just talk to us.
How long have you been out of town?
Just a week, in Palm Springs.
I was on a girls' trip for a friend's 50th.
And are you sure this was on purpose?
I mean, couldn't it have been an accident?
We're not sure of anything just yet.
It is suspicious.
I can't imagine anyone wanting to hurt my son.
What about your husband?
Harry, too, but he...
he made enemies.
Please understand,
he didn't come from money, not like,
well...
Like you?
well...
Like you?
Yes, like me.
I mean, I opened some doors for him, I...
helped his career a bit.
His position on the nuclear committee--
I got him that job.
You said he had enemies.
I got him that job.
You said he had enemies.
Why?
He supported the Yucca Mountain plan,
to store nuclear fuel outside of Vegas.
He thought it was safe and could provide jobs, but
not everyone agreed, so he got death threats.
Oh, God.
This is my fault because I got him that job.
Should I have done something more
about the death threats?
OFFICER: Folks, we need to clear this area.
Mrs. Pallatine, I assure you,
we will do everything we can
to find out what happened to your family.
Mike here will take you someplace safe.
Thank you.
Okay.
CHAVEZ: Who is that?
That is the cavalry.
FOLSOM: What's in this thing-- bricks?
Lead bricks, correct.
Oh.
Lead bricks, correct.
Oh.
You can never have too many of those things
in this line of work.
Thanks for carrying that for me.
It's been, like, 16 years since my last incident,
and it's... Age has caught up to me.
No, thank you. We need all the help we can get.
Okay, you remind me of my nephew.
A handsome genius type?
And humble. Hmm.
And very enthusiastic about his work.
Now ours begins, huh?
Poor Harry Pallatine.
I always liked him.
You knew him?
Oh, not well, but, uh,
you know,
the world of nuclear regulation is small.
And by all accounts, he was a good man.
Didn't deserve this.
No one does.
Hi. You must be the radiation management supervisor.
I am.
Angela Hoppe. Pleasure to meet you.
My team's already in the neighborhood
scouring for radiation,
but I'm gonna be working here,
keeping us all safe.
Great. What do you need from us?
Just your patience and cooperation, really.
My job is to help you do your job safely.
We have a very specific
incidence response playbook to work from.
Step one.
Keep these dosimeters on you at all times.
My team has shut down
all the nearest cell towers to prevent interference.
Oh, that's why my texts weren't going through.
If this ever reads
above 25 rads, you turn around.
You exit the area quickly.
Do not pass go, do not collect $200.
What happens if you don't leave?
You will get sick.
Just like the EMTs who stayed too long in the hot zone.
Hot zone?
That's step two.
Hot zone?
That's step two.
We establish a hot zone around the crime scene
using our dosimeter readings.
Inside that perimeter, only personnel wearing
the class 3 isolation suits I brought are allowed in.
And only 30 minutes at a time.
♪ ♪
Not all of us are as familiar with these regulations.
Is there a literal playbook?
Just stay close to me. I wrote it.
Oh.
WILLOWS: What could be waiting for us in that house?
HOPPE: Cesium-137 from a radiotherapy machine.
Cobalt-60 from a chemical plant.
Metal from a scrapyard. There's no way to know.
I have seen them all before, but first things first:
we need to evacuate this neighborhood now.
Get all the homeowners out.
That is vital. It has to happen now.
Dr. Roby's already working on that.
We're gonna stay here, we're gonna go in.
Mr. Rosner?
Hey, Max, it's not like you to farm out the science.
And you keep checking your phone.
Is everything okay?
Why don't we focus on getting this man out of here.
Mr. Rosner?
What the hell are you doing, man?
I know you heard the evacuation order. You got to go.
I got you. I'm gonna evacuate, of course.
I just need to get
my perishables down into my bunker.
Your bunker?
Most people think it's nuts.
But most people only think what they are told to think.
They take no precautions for the imminent collapse
of the global system. Not me.
You're weirded out.
No, no. I'm interested.
You know
what my dearly departed neighbor did for work.
If you lived next to that you might prepare, too.
My bunker is safe
from chemical attacks, nuclear attacks,
airborne and waterborne viruses...
It seems like you got a problem with Harry.
Problem? No, I had a major ideological feud
with that nuke lover. As far as I'm concerned,
his chickens have finally come home to roost.
Now, which way do you want me to evacuate?
FOLSOM: Five rads here. Is that dangerous?
It's about eight times what we absorb
in a year from the atmosphere alone.
In these suits, for this amount of time, we're safe.
But if you're within a yard of this source
for hours, you're gonna have a bad day.
How do you have a good day with radiation?
HOPPE: By being far away from it.
You ever play "hot and cold" as a kid?
Basically, that's the game here.
Find the hottest spot, find the source.
FOLSOM: 5.1 rads, five rads.
It's not hotter or colder.
Yeah, I'm lukewarm, too. Five, five, five.
4.8 and 5.2 rads all the way down the hallway.
What are you guys seeing?
The same. Everywhere.
Was this entire place dipped in radiation?
PARK: Here.
And here.
It's funny how you found enough lab work
to avoid a radioactive crime scene.
W-What do you mean? I'm champing at the bit
to put on a hazmat suit.
Isolation suit.
You sound just like Chavez.
Well, she and I share
a keen sense of fashion.
How's it going here?
About done inputting
all the dosage readings, then we'll be able
to see where the radiation's hottest in the Pallatine house.
Hopefully spot a pattern that'll point us in the right direction.
Hey, have you noticed anything strange with Max?
Strange how?
Um, she's been off the past couple of days.
You don't think
she has a problem with how I'm running my shift?
No. Max trusts you.
No, she's probably just dealing with some personal stuff.
Yeah, but if she were,
wouldn't you know? You two talk about that kind of thing.
Well, we used to. I mean,
since everything happened with my mom.
Okay. Ready.
Whoa.
Who says data can't be beautiful?
This heat map looks like an early Roy Lichtenstein.
What? I'm cultured.
The radiation really is everywhere.
How's that possible?
It's almost like it's in the walls.
Actually, maybe it is
in the walls. It could be in the pipes.
Gray water.
Gray water?
Gray water.
Gray water?
Does the house even have a water reclamation system?
I don't know. But if it did, any water
that was contaminated by the source
would just cycle through the whole house
over and over, irradiating everything.
That's the bathroom, isn't it?
Yeah.
How far do you think that is?
Got it.
What's that glow?
Cherenkov radiation.
Charged electrons passing through water.
It's cracked.
What is that--
It's cracked.
What is that--
cesium from a hospital
or scrap metal or...
It's-it's a uranium pellet.
Uranium?
It's-it's a uranium pellet.
Uranium?
How the hell would someone get ahold of that?
There's only one way you can.
From a nuclear fuel rod.
Wait, hang on.
There's something on the lid.
Oh, my... What?
That sticker...
That's Harry Pallatine.
So, the killer was leaving us some kind of a message.
How many pellets are in a fuel rod?
Hundreds.
Well, then whoever did this-- there's
plenty left for everyone on this committee.
Yeah.
Hard to believe this is all because of something
the size of a thimble.
Well, you know what the saying.
the size of a thimble.
Well, you know what the saying.
It's not the size of the pellet, it's the motion of the photons.
A motion that killed two people.
Two people who were exposed for days
without shielding, without suiting.
We'll-we'll still make it quick, yeah?
Oh, for sure.
Hey, how's it going out here?
Don't take another step. You're fine right there, but...
No, no, no. I'm just checking in for a second.
It's not every day you have
a mobile nuclear lab in your parking lot.
So what's that gonna tell us?
Nuclear spent fuel's
a smorgasbord. Uranium.
Cesium. Barium. Xenon.
You could throw a dart at a periodic table,
and whatever you land on's probably
gonna be found in that fuel pellet.
Each nucleus
in that pellet creates a huge amount of gamma rays
that fly at the speed of light, ionizing
and destroying everything they can in their wake.
Now, this gamma ray spectrometer--
that's gonna give us the ratio of photons
to gamma rays, and that will tell us...
The age of the pellet, and that way we can
determine the specific reactor that it came from
and, hopefully, that leads us right to the killer?
Five points, Mr. Folsom.
Um, I-I did a little reading.
Let me know when you guys have results.
You got it.
Ready to hold the most dangerous object on earth?
Uh, I guess so.
I got to hand it to you, Josh.
I've seen a lot of tough guys lose their backbone
when it comes to radiation.
You... you did great.
Thank you.
What do we have?
The specific isotope is uranium-235.
Based on the decay rate, it's about ten years old.
Probably from a North American light water reactor.
So this should give LVPD enough to start
narrowing down the search.
Yeah.
(sharp inhale) Mm...
What?
(sharp inhale) Mm...
What?
Spent fuel is, like,
under the tightest security in this country.
How did this go missing?
Are the rest of the people on the committee safe?
They are in protective custody, like you.
Is there anything here that looks familiar?
Uh, not specifically, no.
But Harry did get some death threats
for his support of Yucca Mountain.
He told me he wasn't in danger, but...
Were the death threats anything you found credible?
Anything you remember?
Uh, no, uh...
he threw them all away. He...
he said it was a bunch of nonsense.
No one ever took it into the real world.
Except?
Well, there was Dennis Rosner.
Your neighbor.
You know,
he has enough guns and ammo in that bunker of his
to stage a federal coup.
He keeps every cent of his savings in gold
because he thinks the U.S. dollar's going to collapse.
Maybe he thinks that
killing Harry would save the world.
Well, LVPD is giving him a look.
They're working up a whole list, but I'm...
I'm most focused on how the killer
got on to your property.
I thought we had the best security system
money could buy. I...
We never had a single break-in.
I can't figure out how they got inside.
That's all right. That's our job.
Am I safe?
How do you know there isn't another
radioactive source?
Mrs. Pallatine,
believe me, if there's another source
anywhere in this city, we will find it.
PARK: Each of these dots is a radiation detector.
WLVU, the hospitals, the air force base.
The range on each is pretty limited,
but, put them together...
We've got most of the city covered.
The system was originally designed to locate dirty bombs
but, thanks to Folsom and Ms. Hoppe,
we have it dialed in and looking for uranium-235.
Mm, probably our best shot of getting a quick answer.
Chavez is calling
every nuclear site and storage facility
where the pellet could have been stolen from, but
she's already running into jurisdictional problems.
Well, if any of the pellets from the fuel rod are in Vegas,
they'll trip one of the detectors and, bing-bong-bing,
it'll pop up here.
Chris.
it'll pop up here.
Chris.
Something's going on with Max.
You don't think she's feeling sick
like the EMTs at the scene?
No, I don't think that's it.
Oh, good. You had me worried.
There are other reasons to worry about someone
than them getting blasted with nuclear radiation, you know.
Mm...
WILLOWS: So, now that
the uranium is gone, does that give us
more time in the hot zone?
Well, usually, I'd give us another 15 minutes,
but since we still don't know how the source got inside,
we should play it safe.
Playing it safe and sticky.
It'll take 36 hours
for the house's rad levels to normalize.
So, unless you want to end up like those EMTs...
Say no more. I love my suit.
Just gonna have it tailored next time.
Sand.
Aw, I didn't see this last time.
Oh, God, I hope we didn't track it in.
Well, my treads are clean.
Flag it. Come take a look at this.
What do you got?
That's corrosion
of some kind. I-I saw the same splotch of this stuff earlier.
Acid, maybe? Killer could've
used it to open a lock.
All right, time's up. Coach is subbing us in.
RAJAN: There's orange slices and juice boxes back in the tent for you.
FINADO: Not a moment too soon. I'm wilting.
Be on the lookout
FINADO: Not a moment too soon. I'm wilting.
Be on the lookout
for acid. We found it
in a couple of spots.
FINADO: Good luck.
Hey, welcome back, you two.
FOLSOM: Hey.
Oh. Is that your time?
No, just bad news.
Radiation Management took custody of the fuel pellet,
FBI and NNSA also
took a look, but no point of origin yet.
So they can't point us to the killer?
Well, the best theory is that a fuel rod
was stolen from a transport truck.
But that doesn't narrow it down.
Ugh. I better go.
But I'll be right outside if you need anything, J, okay?
All right, I'll come find you when we're done.
Yeah.
You two are
fast friends, huh, J?
It's nice to work with someone
who appreciates what we do.
Well, bet she'd appreciate it
if we found something left by the killer.
You mean something that isn't uranium?
PARK: Normally, this iron capsule
would be enough to shield the radiation,
but see how it's broken open?
So, what's that residue? Get a swipe of that.
Could that be... rust?
I don't know.
So, we know that rust coats iron, right?
When it's been exposed to elements,
but this looks like something ate through the capsule.
Yep, the splotch was acid.
Muriatic acid strengthened by alum.
Alum's overkill.
Muriatic acid can eat through any metal on its own.
Maybe the killer used it to break open the capsule, too?
ROBY: Nope.
It was bacteria
that broke open the capsule.
Leptothrix, to be exact.
FINADO: Leptothrix?
(chuckles): Oh, that's... that's clever.
It's a metal-eating bacteria.
We used to call it "sewage fungus" back at Dow.
If the killer put some in with the capsule
inside the toilet tank, it was just a matter of time
before the bacteria chewed through to the metal
and released the radiation.
Like a biological fuse, takes days.
Plenty of time for our killer to get far, far away.
Say, to Palm Springs?
Mrs. Pallatine's trip did land at a very opportune time.
How would she have access to that kind of bacteria?
Well, you can get leptothrix from any lab supplier online.
They use it for all sorts of stuff,
like making dirty water drinkable.
I know someone who'd be pretty interested in that.
I'll talk to you,
but there's no way in hell
I'm giving you my DNA.
What's with the sunscreen, man?
In case you haven't heard,
radiation is running amuck in Vegas.
We all have to take precautions.
Sunscreen's not even the worst of it.
I had to liquidate my chickens.
Liquidate?
Those chickens were supposed to feed me
when the global food supply
is contaminated. If they're irradiated--
talk about defeating the purpose.
I'm not gonna play make-believe apocalypse.
I want to talk about your neighbor.
Well, look, I opposed Harry's policies,
but I would never hurt anyone.
I'm a survivor, not a killer.
Tell it to your chickens, man.
Can you pull your collar back for me?
This is getting ridiculous.
Oh, God. What-what have you done to me?
That's not your blood.
What?
Get me out of here!
Angela.
I must have been exposed.
Angela.
I must have been exposed.
Angela...
Stay back, stay back.
ROBY: Angela.
No, no, no.
I've been exposed to...
Hold on, hold on.
It could... This could be nothing.
No, get back.
I'm dead.
APANA: We'll continue testing every few hours
to monitor your vitals,
but in the first draw, we noticed
a low level of lymphocytes in your blood.
Now, it could be any number of things. Infection,
an immune...
Doctor, you know exactly what it is.
an immune...
Doctor, you know exactly what it is.
Lymphocytes are the first thing to drop when
a body's absorbed a fatal dose of radiation.
Well, given the environmental factors that we discussed,
that is a possibility.
Any news?
Only the bad kind. Hi.
APANA: We'll check back in a few hours.
I... I checked your suit.
I thought you'd want to see this.
(scoffs) One tiny mistake.
I always knew the risks. Everyone else is okay?
Yeah, our tests were clean.
The EMTs are still sick,
but there were no red flags in their bloodwork, so...
They didn't handle the source. I did.
You know, you should check
everyone's suits, okay? And go back to the house and-and
retest everything, make sure there's no more contamination.
I just don't want anyone else
to end up here.
Is there anything you need?
I just need a ride home.
I...
do not want to die in this room.
I'll take you.
Yeah?
How is she?
She's got days, not hours. I want another round
of tests for everyone here.
Already ahead of you. We all retested.
Normal lymphocyte levels, no signs of radiation damage.
Angela says that we should
go back to the house to make sure
that there is no radiation that we missed.
Yeah, and we still need to figure out
how the killer broke in.
Whoever did it
brought the muriatic acid there for a reason.
I'm gonna recheck the locks to the house.
This woman deserves answers.
Dr. Apana. Quick question.

FOLSOM: What's with the sunscreen, man?
Sorry. Better safe than radioactive.
Are Beau and Catherine already inside the house?
Yep. On the hunt for sand and acid.
We'd love to find a few more breadcrumbs
on the killer's trail.
Josh.
Your shift doesn't start for another 45 minutes.
We need to expand the search to Dennis Rosner's house.
He might have been using the sunscreen
on his hands to-to hide radiation burns.
Didn't you get my call?
No.
Hoppe shut down the cell towers
to prevent dosimeter interference.
It's been a dead zone ever since.
They're still down? Are you sure?
Yeah.
For sure.
I got to, uh...
I got to check on something. I'll be back.
Oh, hey.
There's no acid on any of the locks.
I'm not seeing any sand, either.
There's no trail at all.
That's not the only thing
that's gone cold. The radiation's completely gone.
Got rid of the source, got rid of the gamma rays.
Well, that's a relief. I can't wait
to get out of this damn suit.
Amen.
I guess Hoppe got exposed before we found the pellet.
RAJAN: Adios, suits.
I've never been more thankful
to see a zero in my life.

Ah.
RAJAN: That would be Dennis Rosner's house.
Ah.
Right where Folsom told us to look.
Found the beach.
And more acid.
This doesn't make sense.
What doesn't?
Is this really the best getaway route?
What doesn't?
Is this really the best getaway route?
Shouldn't you be in an isolation suit by now?
She got an email in the hot zone.
I'm sorry, what?
Hoppe. She shut off the cell tower
to prevent dosimeter interference,
according to her own playbook.
Mm-hmm.
according to her own playbook.
Mm-hmm.
The whole scene's a cellular dead zone.
Hey.
Oh.
This must be the entrance to Rosner's bunker.
Lock looks brand new.
Because the killer dissolved the old one.
And replaced it.
So no one would know where they'd gone.
Even Rosner didn't notice.
Are you saying we have this whole thing backwards?
The killer didn't go through Rosner's backyard
to the Pallatine house.
They went through the house
to get to here.
This is the break-in we've been looking for.
The only way she could have gotten an email
was through the house's Wi-Fi, but...
how would she
have the password?
But she said she and Pallatine
knew one another, right?
Yeah, but she just didn't say how well.
I've been testing the blood from the tissue Hoppe left,
looking for DNA damage from radiation.
Mm-hmm.
There is no DNA damage.
In fact, there's no
human DNA at all.
That tissue's covered in feline blood from her cat.
She faked her own poisoning.
She was lying to us the whole time.
Sounds like she could have killed two people.
I just... I don't know why.
Whoa.
Someone's been down here. Look.
Yeah.
What have we got here?
Whoa.
Rosner's end of the world stash.
There must be millions worth of gold in these bags.
Hmm.
Not anymore there isn't.
We had the motive wrong.
This was a heist.
So, we got played.
Hoppe knew that she'd be called in
for a radiological incident
and she used the playbook that she wrote
to sneak into that nutjob's
bunker and steal all his gold.
Almost all his gold.
She left just enough so Rosner
wouldn't notice right away.
By the time we noticed,
she was gone.
Nobody sees us nice little ladies coming.
You never expect one of your own
to turn into Hans Gruber, do you?
What I don't understand is
how did she haul off all that gold?
I mean, Angela Hoppe's pretty fit for her age,
but she's still just one person.
She hid it in plain sight.
And I helped her.
Hoppe had total authority over that uranium pellet.
She probably had me cart the gold out along with it.
Nobody was gonna risk opening it.
And by faking her poisoning,
she bought herself a few hours to slip away
without anyone noticing.
If Hoppe moved the gold along with the uranium,
then chances are it was irradiated.
Which means we can track it.
Tracking treasure isn't really what the system is built for.
Is it gonna work?
It might. We can thank Ms. Hoppe for that.
She pulled off the exceedingly rare
accidental Goldfinger maneuver
and blasted all her loot with radiation.
Just got off the phone with the folks at WLVU and Nellis.
They got their sensors dialed in
to find some gold that glows in the dark.
Well, Hoppe helped set up the system.
She'll know where all the detectors are
and how to avoid them.
Which is why I sent Beau
and how to avoid them.
Which is why I sent Beau
and an army of volunteers out
with dosimeters. They're fanned out
all over the city. We will find her.
RENEE PALLATINE: Of course
I know Angela Hoppe. She's a good friend of the family.
She said she hardly knew Harry.
She's over for dinner once a month.
We'd laugh about Dennis and his crazy chickens.
I can't believe I trusted her.
We all feel the same way. I'm... I'm sorry.
You know, I-I have calls to make.
Um, if anyone I know sees her, I'll call.
Just, thank you. At least now I know.
I know you're gonna be tempted to
take this personally. Do not.
She played me like a fiddle.
Yep. She saw you needed connection,
she exploited it.
That's not on you, Joshua.
You did a good job.
Thanks, boss.
You'll be all right.
Will you be?
You seemed distant today, I don't know.
Preoccupied.
Is something going on with Bryan?
CHAVEZ: Hey, we got a hit.
I-11 near Railroad Pass. We found her.
How's your leg healing up?
We retested your blood--
your real blood-- from the hospital.
You took corticosteroids
to lower your lymphocytes temporarily.
You were never dying.
We also found where the uranium pellet came from.
A truck from the McKittrick Bay nuclear reactor in California
transporting spent fuel to a facility in New Mexico.
RAJAN: Thanks to your position
with radiation management,
you could easily hide the theft.
It was under lock and key,
but you had an answer to that.
Just change one number on a spreadsheet.
It was a very thorough plan.
Just like your incident response playbook.
Genius, really.
I mean... (chuckles)
Well, I don't know about that. Look where I am.
You made a mistake with the gold.
You don't understand.
Nobody was supposed to die,
not Harry, not his son. That was my failure.
You hid a radioactive pellet
in the Pallatines' house.
What'd you think was gonna happen?
Harry knew the symptoms of radiation poisoning.
I assumed he'd call it in long before
he absorbed a fatal dose.
Then everyone
in the neighborhood would evacuate,
I'd get in...
Nobody had to die.
But you didn't care if they did.
I've spent 38 years
working for the people of Nevada.
I'd have to spend another 40 just to
retire on cheap beer and peanuts.
I just wanted...
one last shot at the good life.
Your shot
cost two people their lives, Angela.
Give it another 30 years.
Maybe when you're my age, you'll-you'll understand.
No. No.
I never will.
CHAVEZ: All right, hands behind your back.
Let's go.
The gold's been returned to Dennis Rosner.
Would you believe he didn't say thank you?
RAJAN: He made a stink about
needing to decontaminate it all, but that's his problem.
I may have failed to mention that
it's not a health risk and won't be radiated after two days.
So, we're all wrapped up there then, huh?
Yeah, on that--
we're wondering about you.
You've seemed off lately.
It's not how I'm handling my supervisor role, is it?
No, Allie, no.
Then what is it?
Close the door.
So, you're right.
I have been distracted.
I've been working another case.
What case?
The Robert Cuevas murder.
Remember? The poor soul
who was killed at that robot factory?
M-Max, that case is closed.
Uh, there is another reason why
I have kept Ocho around.
It's not because he's such a great conversationalist.
What is that?
So, you remember Cliff Roland?
There was a last sliver
of a photo in his camera,
so I developed it in the trace lab.
When I saw you crying...
Yeah, I got some fumes in my eyes.
That's what you were talking to
the doctor about at the hospital.
Yeah.
He gave me some eyedrops. But the point is
I developed the photo.
There was someone else there when the murder went down.
I'd say we've got a platinum blonde person of interest.
CHAVEZ: I take it back.
This case isn't closed.
No, ma'am.
This case isn't closed.
No, ma'am.
Not anymore.
