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?

♪ Who... are you? ♪

♪ Who, who, who, who? ♪

♪ Who... are you? ♪

♪ Are you! ♪

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?

Mm-mm.
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.

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.
