Mom, I know what's going on.

If you're running
product for these guys,

I can't help you.
Previously on CSI: Vegas...

They killed her, she's gone.

You cannot investigate

the death of a family member.

Jeanette Folsom. Who did it?

Raphael Tarquenio...
is that your boss?

I'm not telling either
one of you a damn thing.

I found the guy who did it.

Kahn Schefter killed my mother.

Josh was officially charged.

I'm looking for
Raphael Tarquenio.

How long has it been?

Not nearly long enough.

I killed Kahn Schefter.

So we're supposed to believe

this was your idea?

I trust this
concludes the matter.

Murder charges got dropped.

I want to say thank you

for believing in me.

I'm not sure you're gonna
keep your job, Josh.

I saw that, Hernandez.

The four-month sleep
regression is no joke.

Where's the cavalry?

Oh, should be here soon.

Till then it's just us

and the body.

- What do we know?
- Not a whole lot.

A fisherman called 911

when he saw a stranger
trespassing on the dock.

Which, in hindsight, may
have been a bad idea.

Gunshots rang out on the call,
then the line went dead and...

So did the caller.

Explains the dead body.

And what about the container?

Your guess is as good as mine.

Well, let's not guess.

What?

Whoa! Slow down!

Officer Hernandez
died in an instant.

It's a miracle I didn't, too.

When I came to in the
hospital the next day,

I was told that my camera,

the dead body and that
yellow plastic container,

- all gone.
- The whole crime scene was wiped.

Like it never happened.

Whoever it was got
what they came for.

Case was never solved.

- What are you thinking?
- The thing I've never been able to shake

is that I recognized
that car that hit us.

It was part of this drug
investigation I'd been working.

- Raphael Tarquenio?
- One of his associates.

God, the man needs
to go down, Max.

Lord knows.

- Joshua agrees with you.
- Well, the problem is,

the SUV was never found.

We were never able
to establish a link

between Tarquenio and the boat.

The man is my white whale,
and I could never prove

that he even got onto the water.

Until now, maybe.

Look what I found at his house.

Boss.

Hey. You asked to see me?

Yeah.

I'm gonna go back to the boat,
pick up where I left off.

I'll let you know when it's
time to start the engines.

Go get him, Ahab.

So

These time cards are
now your responsibility.

Happy days.

I know you and I knocked heads

over your idea to
partner people up...

It's okay. No need to apologize.

I wasn't planning on it.

So, you partnered

Catherine and Beau,
and Chris and Penny up.

Mm-hmm.

Any of them have a say in it?

No.

Do you care to reveal why

- those would be. - The best pairings?
- I have my reasons.

Of course, I told them

that I drew their
names out of a hat.

I didn't want anyone to object.

Okay, the pairings worked before
you knew they were permanent.

Hmm.

Two heads are always
better than one.

You'll see.

I'll get right on these.

You don't have to go.

I know things have been

complicated lately,

but you can stay.

I don't bite.

Yeah, well, I'd
just keep you up.

I'm spooked about my date with
Internal Affairs tomorrow.

Hey.

You have the Garrity rule.

Use it. You don't
have to say a thing.

You shouldn't say a thing.

Yeah. Still, I should go.

Damn it.

Well, it was worth a shot.

I've taken a dozen shots

against Tarquenio.

I need one of them to land.

Are you okay?

Catherine.

If we're gonna be
partners, you should know.

I-I don't do well
with long silences.

I just took a breath.

Yeah, good. Good.
Get it out of there.

Don't let it fester.

Okay.

You leave me no choice.

Fill the gap, I will.

You know, I think...

I think I could be a
boat guy in my next life.

Although the idea of a life
without socks freaks me out.

But, you know, the-the... the
wind in your hair, the sun.

It's not really my thing.

Right.

Yeah, yeah.

It's downright depressing
when you think about

what the drought's
done to the waterline.

I mean, look at the
dock here, this tangle,

the fishing line, it didn't
look like that a few years back.

Here.

Look.

Today. 2019. Today.

2019. Today.

Y-Yeah, yeah, yeah. H-Hold
on a second. Just...

What?

Is that a prosthetic limb?

What looked like the top
of a bumper back then...

- No, it couldn't be.
- Yeah, i-it could be.

Let's get it out.

All right.

Holy mackerel. It's a leg.

That is one funky plastic leg.

Wow. This thing's been
in the lake so long,

it has its own ecosystem.

I need help figuring
out how to clean it off.

Beau's still on the water,

seeing what else
he can dredge up.

What are you hoping to find?

Proof that this
prosthetic is somehow tied

to Raphael Tarquenio.

I'm convinced that he is
connected to that dock

where this leg bobbed up.

Well, we can't use bleach
as a cleaning agent.

No, it would destroy the algae

but also any remote
chance of usable DNA.

And it'd require scrubbing,

which would compromise
the integrity of

whatever evidence we do find.

No, we need something
that's gonna break the bond

between the algae cells.

Maybe an oxidizing agent.

Something that causes
free radical formations.

Sodium carbonate and water.

I'm so glad you two
found each other.

Wait.

Look at that.

Something corroded the
metal on the prosthetic.

But the plastic's
totally intact.

Only a few types of chromic
acids could have done this.

I wonder if the person
attached to this leg

was dissolved the same way.

Dark.

Well, it might explain
that plastic bin

I found on the boat that night.

Maybe all the contents were
just dumped in the lake,

leg and all.

The, uh, leg's serial
number was eaten away,

but, look, the atomic pattern
was still down in there.

EBSD machine just gave us this.

Entering the serial number

into the national
arthroplasty register,

and... Theresa Moren.

Looks like she's a dean at
a prep school here in Vegas.

Or at least was.

So, what's her leg doing in
the middle of Lake Mohave?

I don't know, but
check out that caption.

"Farnsworth Prep's
Jocelyn Tarquenio

sinks a three-pointer."

Raphael Tarquenio has a daughter
who just so happens to go

to the school whose
dean lost her leg?

I can see him raising Dobermans.

But a sweet little
shooting guard?

And according to
her obit, she died

in a scuba diving
accident in Mexico.

The body was never found.

Check out the date. Dean
Moren died five years ago.

That's the same week that I
was almost run over by the SUV.

Best question in Vegas:
What are the odds?

I didn't want to believe it, but

this does look like Mom's.

Courtney, this is Max Roby,
she runs the crime lab

here at CSI.Hey.

So... so you do think
there was a crime?

The detectives back then,

they told me Mom
died on a scuba trip.

Well, there is quite a bit of
evidence that said that she did.

Your mom was never seen

after school ended that Friday.

Her car was found in Baja at
a scuba shop in Punta Azul.

I know.

My mom and I weren't
that close at the end,

but that story never
sat right with me.

Had she ever scuba'd before?

Before she lost her leg, yes.

But after it was
amputated, never.

But you said you
two weren't close, so...

Even at our worst,

I knew when she was traveling.

She never called.

Does the name Raphael
Tarquenio mean anything to you?

It rings a bell,

but I'm not sure why.

Wait, he's one of
Mom's big donors

at Farnsworth Prep, right?

I don't mean to make
this about me, but

what's the LVPD angle here?

What do you mean?

I mean, how is a prosthetic

going to help us take
down a narco-trafficker

who had Josh's mom killed?

We don't know that it will.

I mean,

- we don't know yet.
- That could change

if we could prove someone
in the Tarquenio camp

had access to the specific acid

that was used on Dean
Moren's leg five years ago.

And that Tarquenio staged Dean
Moren's death down in Baja.

And that he stole everything
of value from the crime scene

on that boat five years ago.

Should be no sweat.

I mean, we already
have a plastic leg.

A plastic leg which showed up

right next to the spot
where a cop was killed.

All right. Let's
reopen some cases.

Okay, let's figure
out what made this

look like this.

Go ahead and add sulfuric acid

to the no-no list.

It's eating through the
metal, the plastic...

Oh, the table.

You're never going to pin
this down on Tarquenio

if we can't even
find the right acid.

There are still
dozens more to try.

These are just
over-the-counter basics.

Dean Moren was last
seen at Farnsworth Prep.

Maybe someone there
brewed up something

more unique in their chem lab.

I still think it
needs to be chromic.

How about a break? We've been
at this for over an hour.

Weak. An hour is nothing.

I can hold a plank for an hour.

No, you can't.

Are you doubting me?

Let's go right now.

I'm serious. I'm
warmed up. Let's go.

Guys.

Whoa, she's pregnant.

This can't be good.

Guess she's making more
little IAB detectives.

Who is that?

That's Nora Cross.
Internal Affairs.

She spent some time here
before you came along.

You don't think...?

I do.

I think she's handling
Folsom's inquiry.

She looks nice, right?

Sweet, even?

That's the face you see before
the axe falls on your neck.

They really sent the one
IAB detective I know?

Prior knowledge of a suspect

is actually a good thing
in my line of work.

But do you want to talk
about conflicts of interest?

We could start with you
springing Trey Cahill from jail.

Guy you arrested
a few days prior?

I-I've known him
since we were kids.

I wish I was better at keeping
in touch with old friends.

Carolyn Lim, Brittney Tichey...

We don't even swap
Christmas cards,

much less post
each other's bail.

Well, I'm here to answer
any questions I can.

Okay.

Here's one.

Why did you cover for Trey

during Kahn Schefter's
murder investigation?

You can stay mum.

Obviously, your union
rep's advised you.

But your conduct in the
time that you and Trey spent

with Mr. Schefter,
that's what is at issue.

You can ask. I-I...

I don't remember all of it.

Truly.

But

go ahead.

Nah.

- This isn't going to work.
- Wait, is that it?

Are you going to talk
to my co-workers? No.

I'm gonna talk to you tomorrow

at the hangar where Trey
brought Mr. Schefter to you.

We clearly need
to do what we can

to refresh your memory.

Raphael Tarquenio? Yeah. Gosh.

I got to be honest. I
barely know the man.

Aren't you the dean here?

Yeah, and I try to
meet all of our donors.

But Mr. Tarquenio likes
to keep to himself.

- Tarquenio Fieldhouse.
- Fancy.

It has been a labor of love.

We spent the past five years
refurbishing this, uh, old gym.

Five years?

So, is there anywhere we'd
find chromic acid on campus?

I don't think so.

And I used to be the head
of the science department,

so I would know. To be fair,

I'm just a biologist.
It's a hard "cell."

"Cell." Nice.

Just to be on the safe side,

we'd like to visit
the science lab.

Yeah, whatever you need.
Yeah, right this way.

Are you investigating or
kissing this guy's ass

to get your daughters
into school here?

Little bit of both.

Fieldhouse may be the
jewel of the campus,

but this is my pride and joy.

It's not a science lab,
it's a maker's lab.

A maker's lab.

You've got robotics, uh,
you can make pottery.

Look at that huge
3D printer. Wow.

He excites easily.

He's a man after my own heart.

Looking at atoms all
day can be Bohr-ing.

Yeah?

- Let me show you something.
- Okay.

You two knock yourselves out.
I'm gonna take a look around.

This is the latest and greatest.

Oh.

Yeah. You're not
allowed back here.

I'm with CSI.

I'm investigating
Dean Moren's death

from a few years ago.

I'm new here, but apparently
everyone loved her.

Do you know Raphael
Tarquenio? He was...

Yeah, I know who he is, we
all do. His nightmare daughter

was supposed to be
expelled a few years ago,

and all the teachers keep
praying it'll still happen.

Which it won't if he keeps
writing those fat checks.

Right.

Have you ever seen anything like

chromic acid around the school?

No. You really wouldn't find
something like that at a school.

More like an
aeronautics facility.

Maybe a construction site.

Excuse me.

Allie Rajan.

Hey, Allie.

So, no chromic
acid at the school,

but what if Tarquenio uses it

at one of his legit businesses?

Afraid you're going to have
to put that back, ladies.

Raphael Tarquenio, in the flesh.

Unless he gave you
permission to, uh,

test the lumber
without a warrant?

Congratulations. We visited a
couple of your projects today.

It seems that
business is booming.

At least, your legitimate one.

All my business is
legitimate, Ms. Willows.

You don't have anything
that says otherwise.

Don't be so sure.

We collected samples

of lumber from your job sites.

A lot of it has been treated
with CCAs, chromic acid.

And your point is?

Weather-proofing lumber

is one of its more
productive uses.

But it's also great
at dissolving bodies.

It's time for you two to go.

We were just leaving.

Ah. Can you run the
other tests by yourself?

I have to go. Sorry.

Everything okay?

I don't know. Sorry.

That bad? What happened?

Nora Cross. She
does her homework.

She kind of made it seem
like I was already screwed.

Maybe she's bluffing.

Although

she did email me,

asking to meet her at
the hangar tomorrow.

I'll be there, too.

Okay.

Hey, Allie,

I saw a piece of paper
sticking out of her file,

like a little note.

And?

I could've sworn it was
in Serena's handwriting.

What, she never
mentioned Nora before?

You don't think...

I really don't
know what to think.

Oh, speak of the devil.

Chavez, hi. What's going on?

All right. I'm on my way.

- What was that about?
- Just a case.

She was updating
the very important

new day shift supervisor
on a development.

That's right. H-How's it going?

Trying something new. Partners.

Oh. Yeah.

Max isn't quite on board,

but fake it till
you make it, right?

You'll make it. Hey.

I was meant to be
making you feel better.

You did.

Go on. I'll see you tomorrow.

What's going on?

School janitor went
to empty the trash

and instead found this.

Okay.

There's enough blood
here for someone

to have died from
exsanguination.

Only problem is,

I don't see a body.

There isn't one.

Oh, and by the way?

Dean Canto never showed up
at a fundraiser tonight.

He can't be reached.

I think he's missing.

The kiln's been on.

Ooh.

What is it?

Well

it's not a ceramic vase.

I think I recognize
that gold watch.

Dean Canto was wearing
it earlier today.

So, uh, for anyone
keeping score,

that makes two dead deans.

Whatever happened here was ugly.

Even this guy got
his butt kicked.

Better than being melted
in a kiln. Savage.

That is his M.O.

You think Tarquenio is
behind the dead dean, too?

24 hours after we started asking

questions, another
body disappears.

Almost disappears.

You know, there might
not be chromic acid here.

But there may be the ingredients

with which to
titrate chromic acid.

Can somebody help me
open the door, please?

For what it's worth,

I never believed that
whole scuba story.

I even filed a missing
person report back in 2019.

What do you think
really happened?

I was working one night and

you know, minding my business,

and I hear this loud
fight, lots of yelling.

It was Dean Moren and
that Fieldhouse guy.

Raphael Tarquenio?

About a month before
she disappeared.

I don't know what she did
to get him riled, but...

I thought maybe
that Tarquenio guy

he was the wrong dude
to get tangled with.

How's it feel to be
back? Scene of the crime.

What crime?

You tell me.

Mr. Folsom, the last time

I was called out to CSI,

I wrote a glowing report
about how honest you all were.

I don't mean to make
your job harder for you,

but, um, I'd like to keep mine.

I get it. You
don't have to talk,

but you might want to speak
up in your own defense.

Let's see where the
evidence leads us.

Allie, what do we have?

It's pretty thin.

Um, the padlock on
the gate was cut.

We found a box cutter
on the ground here

that was covered in blood
that we later confirmed

belonged to Kahn Schefter.

Luminol was sprayed
around the area.

A large circle, about
five feet in diameter,

fluoresced. The
reactant was bleach.

Did you clean up blood here?

No DNA or blood
proteins were recovered.

No fingerprints either,
for that matter.

There were none in
the entire caged area.

Someone knew how to clean
up after themselves.

Didn't they, Mr. Folsom?

Uh, that is

a reasonable deduction.

All I'll tell you is,

Trey and I were here that night

with Kahn Schefter.

We asked him who
had killed my mom,

and eventually

we realized it was him.

Josh.

- And then?
- And then we left.

Allie, a moment?

Can you be neutral here or not?

Yeah, of course I can. Good.

'Cause if that's all
we're getting out of him,

this inquiry is gonna hinge on
what little evidence we do have.

- Where did you get this?
- Serena.

Detective Chavez.

She had to relinquish her file.

Run the blood for me.

Let me know what you find.

Something on your
mind, Catherine?

- What's with the side-eye?
- Nothing.

I'm just, uh,

picking my moment
to ask about Folsom.

You think he'll be able
to get his job back?

Let's just say I'm
glad it's not up to me.

It's up to the review board.

I am having a hard time

compartmentalizing this one.

Sometimes it's impossible.

Sometimes work is personal.

I've noticed that.

Are you turning
this around on me?

I see how you get
around Tarquenio.

All I'm saying is, I
do not need another one

of my CSIs self-destructing.

That's fair.

Will you look at that?

The blood from the maker's lab

at Farnsworth Prep
came from not one

but two sources.

Oh, whoa. You've been busy.

What am I looking at?

Blue is the attacker.

Red is Dean Canto, I assume.

Neither was in CODIS?

Nope. We should have a
DNA match on the vic soon,

assuming it was the guy

- who bled a lot more.
- Then we should iso

the blue stuff,
the killer's blood.

It might tell us

how many injuries he sustained,

how tall he is, handedness.

We just have to go blow by blow.

It started over here.

Three instances

of medium-velocity
red blood spatter.

Suggests the attacker
was punching the dean

in the head.

We have height,
width, directionality

of each blood drop from the
crime scene. Who did this?

It's exquisite.

Max.

Boss did most of the work.

Trigonometry should do the rest.

Best day ever.

Okay, I'll go get
my lucky protractor.

Yes!

Oh, my goodness.

How long have you been
in here with these fumes?

It's not working.

Yeah. So I can sense.

I haven't been able to titrate
the acid that deteriorated

Dean Moren's prosthetic using

the materials from
the maker's lab.

I can't do it at all, actually.

I-I don't know how the killer

ginned up his special brew.

Everything I do is either

too strong or it's
not strong enough.

- Maybe it's time to call it.
- Mm.

Maybe grab something to eat?

In that case, I'm going to take
your very strong physical cues

and, for the sake of our

still blossoming partnership,

I'm gonna leave you to it.

Chavez, can I speak
with you a moment?

Yeah.

What's up?

How long have you
known Nora Cross?

You acted like you
never met her before,

but that's not true, is it?

I used to know her a little.

How?

Should I go ask her?

Nora recommended me for
this post at CSI last year.

After the David Hodges mess,

there was a general consensus,
that someone from LVPD

should keep tabs on folks here.

So, you're informing on us?

This isn't a crime family,
Allie. It was oversight.

- I was just doing my job.
- Does Folsom know?

You never told him either.

I will.

Let me be the one to tell him.

Please.

I'll give you a day.

Good morning.

Allie.

Hey.

That's the same shirt
from yesterday. And you.

Did you both stay
here all night?

Oh, there's about to be coffee.

Do you want some?
We've had a lot.

Well, at least you're not
at each other's throats.

Oh, we're not fighting.
We're fighting the math.

13 hours.

We've been checking and
re-checking the equations.

All we know is that

the person who was
getting hit repeatedly

on the head is only five-eight.

I thought Dean Canto
was taller than that.

Correct. He's six-two.

That's a significant difference.

It's way outside of
our fudge factor range.

- Meaning what?
- Meaning we're still missing something.

Because, the way we've got it,

Dean Canto won the fight.

Then how did he end
up inside a kiln?

You know I want this guy, Max.

- Anything I can do to help?
- Well,

you know I love
to share the rock,

but sometimes you got to

you got to go hard in
the paint yourself.

What constitutes a swish?

I am trying to get

a positive I.D.

on the body that
was in the kiln.

And it is a delicate dance.

How delicate is it?

- 89% failure rate.
- Oh.

Yeah.

Okay. So,

the ash from the kiln

was heated at 2,400 degrees,

and I am using an
enzyme solution

to remove the nitrogenous
bases... excuse me,

and I am gonna try and repair

the tears in this DNA.

Damn it. I missed it.

Well, you did say the
failure rate was 89%.

No excuses. Excuses
are for other folks.

Hey, Max, it's okay.

I mean, this sample
may be kaput,

but there's other
ways to test ash.

Let's pop over to Trace

and see what else
burned up in that kiln.

Okay, what do we got?

FTIR says

the ash contains a cocktail

of mercury, lead,
antimony, beryllium.

Chromium, cobalt, arsenic,

and iron oxide.

Put it all together and you get?

Color tattoo ink.

But this guy, he-he was a
dean of a fancy prep school.

Did he look like the type to
have sleeves under his sleeves?

I'd be surprised. I mean,
he'd have to be covered in ink

to reach this level
of concentration.

Maybe the residue is
from something else.

Or maybe the body in the kiln

wasn't Dean Canto.

That would square with
Chris and Penny's findings,

but how did his watch
get in the kiln?

That's the question.

Why just make it look
like Dean Canto died?

I did it.

Oh! I did it. I did it.

Hello? Hello?

Hey, uh, don't-don't you
want to see how it works?

Of course we want to see how it
works, but you sent us all away.

Right. Sorry. Uh, I was putting
too much distilled water

to the chrome oxide earlier.

My-my paste wasn't getting
pasty enough, but now...

- You did it?
- Yeah.

Ugh.

- What was that weirdness?
- Sorry. I think

we only get, like,
two out of the five.

I mean, only a serious chemist

could figure out this cocktail.

I sincerely doubt that.

Tarquenio or any of the goons
he has cutting his drugs

have my chops.

I still couldn't tell
you who did this.

Yeah, I know.

This is the last thing I
want to be doing either.

It is not that.

I ruined a sample earlier.

Can we assume

that your heart is
functioning well

with all that
additional beeping?

I kind of need to focus.

Oh. Oh.

- What?
- I see what's going on.

You have the yips.

I do not have the yips.

I'm mad at myself.

Would it help you to be
mad at someone else? Yeah.

Chavez has been reporting on us

to the I.A.

Wait, you knew she was a plant?

Chavez is not a plant.

She was assigned
here to make sure

that we are doing
things by the book,

which we were,
which we still are.

Which is why there was not
any need for anyone to know.

Any professional reason, maybe.

Folsom didn't even know.

It's none of my business.

Is it yours?

Whoa.

When it rains, it damn pours.

The blood on this photo
belongs to Joshua's mother.

That's better than
Kahn Schefter's, right?

No.

It might be worse.

Where did he get it from,

if he didn't steal
it from the morgue?

Why would he do that?

That is Nora's job
to figure it out.

But I do have to tell her.

The case I was
working five years ago

when I was almost mowed
down... this... Mm-hmm.

Is the man I saw
painting the gym

at Farnsworth Prep
the other day.

- I knew I recognized him.
- Look at all those tattoos.

Tarquenio has the contract
to refurbish the gym.

He's got his guys crawling
all over that campus.

And maybe it was his skeleton
that we found in the kiln, huh?

Self-defense? Could
be why Dean Canto

made it look like he had died.

Or maybe it's more
sinister than that.

Maybe Paul Canto killed
Dean Moren for her job.

And didn't want to stick around
and answer questions about it.

If he's still
alive, he's gonna...

Come on, now.

I have been through the
security footage twice.

Cameras never caught Dean
Canto leaving campus.

He was definitely injured
in the maker's lab.

I mean, we were wrong about
whose blood was whose,

but there was plenty of both.

I'd guess he's hurt
and he's hiding?

Out of view of the cameras.

Dean Canto, come out, come
out, wherever you are.

He's here.

Yeah, we need an ambulance
at Farnsworth Prep.

Stabbing victim,

- near sepsis.
- I'm a dead man.

No, no. Hey, hey. You're
gonna stay right here, buddy.

Who did this to you?

Who do you think?

I got to ask: Why hunker
down in the cafeteria, man?

I-I was gonna get away.
I was gonna sneak out

in a food delivery
truck on Monday night.

- And I almost made it.
- That's five stars.

You were in sepsis with
a lacerated G.I. tract.

You were never gonna make it.

You owe us your life.

And some answers. Start
from the beginning.

The beginning of what?

You started working
for Tarquenio.

I-It started... with his
"donation" for our gym.

He gave us $13 million
for that project,

but it was contingent on
his construction company

doing the work, for
a fee of $13 million.

He was laundering his dirty
money through the school,

and you helped him.

You got in bed with a drug lord.

Never stopped
passing yourself off

as an educator,
though, a-a scientist.

I was looking for a way out.

Then you folks came around,
you started asking questions.

Why did Tarquenio target you?

Because...

I knew what he
did to Dean Moren.

She made the mistake of
turning his donation down.

Mr. Tarquenio did not like that.

Which is why he finished
her off himself.

Can you prove that?

I might be able to tell you

more details if

witness protection
is on the table.

For an accomplice in a homicide?

Oh, dream on.

You mixed up the chromic
acid for him, didn't you?

I wasn't there when
he used it, I swear.

I just made the juice.

If you want our help, you got
to give us something concrete.

Something that ties Tarquenio
to Dean Moren's murder.

The boat, the container

that was stolen from
the old crime scene.

Something!

I wasn't there.

But Tarquenio did hurt himself

when he was... melting her.

The next day he had a bandage

on his hand and he still
has a scar from that.

There was a keloid scar
on Tarquenio's hand.

Keloids are caused by the
buildup of excess collagen.

- Right?
- Yeah, and sometimes

they're formed around
a foreign contaminant.

Did you ever get a
medical warrant, Beau?

Ow!

Ow. You okay?

You could just tell us
how you got the scar.

Why it never healed properly.

Why you didn't have a
doctor take a look at it.

Go to hell, Willows.

Or better yet,

you could just explain what
really happened to Dean Moren.

Here goes nothing.

You flooded this city
with fentanyl and heroin.

You don't have any proof.

You sent someone to a
crime scene five years ago,

and had a good man killed.

You've never had any proof.

You ordered Jeanette
Folsom's murder.

None.

You're right. I can't
prove any of that.

Because

you've always kept
your hands clean.

Until you didn't.

I hurt my hand in
a panini press.

Oh, yeah?

Was it a steak sandwich?

Because there was
a bone in there.

When chromic acid goes to work

on the calcium
phosphate in bone,

you get jagged little
chunks that dissolve

until there's nothing left.

Unless they don't
stay in the solution.

You've been carrying around
a damning little piece

of Dean Moren in your scar

for years.

And I can prove that.

I was just saying
it the other day.

Sometimes it's not business.

Sometimes it is personal.

And I got to tell you,

this one

feels damn good.

How did, uh...?

It's over, Josh.

It's over.

The blood on the photo
belonged to Folsom's mother?

It'll be interesting to see how
the review board interprets it.

Well, I can make one prediction.

They won't.

They'll ask you to interpret it.

Wait, what?!

They want you to testify.

You know the science.

You know the man.

They want me to put
a nail in his coffin.

They want you to do your job.

I can't believe...

I'm sorry.

- I really am.
- Yeah.

Yeah.

Yeah?

- Max?
- Yeah?

Are you doing okay?

Yeah, I'm fine. What is it?

It's just...

Did you ask everyone how the
partnerships were working out?

It might have come up.

I don't understand.

Why can't you just
trust me with my idea?

Because of this.

In my time of running this lab,

I have had exactly one CSI

who permanently
partnered with anybody.

Folsom, he chose you.

And I cannot help
but notice that

he is the only one

who stopped being
accountable to me.

Those two things are
completely unrelated.

Have you ever accidentally

started a fire in a lab?

I have, yeah.

I think everyone probably has.

The most important

type of chemistry in this lab

is between people.

They bond.

They break apart.

And they are just
as combustible.

You put them over an open flame,

you better keep an eye on them.

Mm.

Hey.

Hey.

You're already ready for bed?

I want to get to sleep early.

I got the review board at
8:00. Pizza if you're hungry.

I-I'm probably not staying.

Um...

I couldn't tell you this before.

And then it was
never the right time.

Tell me what?

I didn't just land at CSI, Josh.

I was assigned to the lab

to monitor things after the
David Hodges investigation

for Nora Cross.

I just wanted you to know.

Why are you telling me this now?

Maybe if we'd both
been more open,

it'd be different,

but things haven't been right

between us for a while.

And I know a part of you
will never forgive me.

But I think we both
know this isn't working.

"This isn't working"?
Yeah. I mean,

but was it ever working,
or was it always just work?

That's not fair.

This was real.

Um... tomorrow's a big day.

And I still completely
support you.

I mean it.

Yeah, uh, thanks.

I think I'm probably

better off alone.

Mm-hmm.
