Cuatro, what just happened?

[GASPS]

What the...?

[SCREAMS]

Oh, hold it.

Oh.

Hey.

We don't have to be...

Look, I know we're
not together anymore...

[ELEVATOR BELL CHIMES]

- Good morning.
- Hey.

I'm sorry.

No...

How have you been?

I'm, uh, I'm fine.

We should still be able
to talk, you know?

- Share stuff.
- [FOLSOM LAUGHS]

CHAVEZ: It's not like I'm
still reporting on you guys

to Internal Affairs anymore.

And the venue was so great and...

But there's no pressure
to set a date, though.

No pressure at all.
I was just writing in the future log

in my b*llet journal.

Maybe you're not
a "long-term plan" kind of gal.

Also cool.

Everything okay?

Did you just hear what Chavez said?

- Uh, uh, no, no. What?
- Detective Chavez.

She just said it's not like
she's still reporting

on us guys to Internal Affairs anymore.

Not like she's still, as in she was.

Chavez was reporting on us
to Internal Affairs.

All of us. In secret.

Probably this whole time.

Which is... bad.

I-I can't believe this. I got to go.

Yeah.

[SIGHS]

[INDISTINCT CHATTER]

Smile, Allie, you're on camera.

Don't get too excited.
Some kind of power surge

knocked everything offline.

Cameras, motion sensors,

and most of the robots.

Most of the robots?

Mm-hmm. They cleared them
all out for us.

And apparently they call
this place a "dark factory."

Machines run all night,

and they set up for human
workers the next day.

They weren't just using the machines.

Look, they were building them.

CHAVEZ: So, robots building robots.

RAJAN: Robots all the way down.

The overnight shift is maintained

by just one man. Well, it was.

Robert Cuevas, 48.

Worked in this factory
the last eight years.

Contusions here and here.

Probably some more here.

So cause could be blunt force trauma.

Hey, what do you make of this?

- FOLSOM: Whoa.
- CHAVEZ: Whoa?

What's whoa?

This spatter is all over the map.

It came from only a handful of impacts,

but the size of the blood droplets...

These are around four millimeters.

These are maybe two, 2.5.

All normal.

Those are one millimeter.

Less than a millimeter
means really fast,

like a b*llet or a table saw.

But the pattern is similar
to a blunt impact.

- Like a punch.
- SABRINA: Hi.

Hi there.

Sorry to bother. Sorry.

I'm Sabrina, Mr. Thomas's assistant.

Mr. Thomas?

The owner of this company,
among many others.

I was asked to let you know
that the techs

who found Mr. Cuevas's body are here

if you maybe want to talk to them.

Yeah.

Hey.

A man lay dying with all these machines

moving and working all around him, huh?

It's kind of dehumanizing.

ROBY: Wait a minute.

Is that blood?

RAJAN: Yeah, there's more here.

ROBY: Allie.

RAJAN: Are those hairs?

ROBY: Yep.

Same color as our victim's, right?

Well...

Did they go out that way or...?

Let's see.

Look there. It's going this way.

That's a bit bizarre, right?

[POWERS UP]

Hey there, little fella.

So, you didn't k*ll him, did you?

[WHISTLING]

Hey, where's your little bestie?

Beau and I drove separately.

Believe me, we see enough of each other
under Allie's partner system.

You don't really think that
a robot k*lled that guy, do you?

Well, the experts say
it couldn't happen.

RGB/lidar array combined with
a proximity guidance system

means it can see perfectly.

It couldn't collide with objects.

We built it to not collide with objects.

Thank you for that
very thorough explanation,

which wasn't an answer to my question.

Is it literally impossible

for one of these machines
to hurt someone?

CLIFF: We've been building
these guys for six years.

Never had an injury.

Well, Bill burnt his hand

on a soldering iron last month.

We've never had
a robot-related accident.

Okay, what if it wasn't an accident?

Could someone tamper
with one of these things

to make it more dangerous?

Well, I ran diagnostics
on the bloody one, uh, Ocho.

Uh, Ocho's his name
because he's the eighth robot.

Would it surprise you to learn
I speak Spanish?

Right.

Well, he's as good as he was
fresh off the assembly line.

Uh, nobody's tampered with him.

But the robots can be controlled. Right?

Like a person drives a car.

Who here could get behind the
wheel of one of these things?

Our bipedal hydraulic humanoid robots

use keyframe programming
and a suite of AI tools

to operate.

That takes experience, but,

I guess a lot of the folks who
work here could figure it out.

At least in theory. I just think...

Hey, hey!

Hey, hey.

Hey, what do you think you're doing?

That's proprietary technology.

Well, this proprietary technology

is at the very least a m*rder w*apon.

Or an actual m*rder*r.

Either this man-made machine
k*lled Mr. Cuevas...

or that's what somebody
wants us to think.

Either way, some person is responsible.

Ocho and the blood spatter...

that's all the evidence we've got,
so, yeah, he is coming with us.

[MACHINE WHIRRING]

Beau, that Roomba's headed
toward my blood spatter.

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

I got it. I got it.

JACK: I'm fine.

Just weird doing an autopsy

where the k*ller might actually
be in the same room as me.

Max and Allie are here.

Love you. Uh, listen to
your physical therapist.

[CHUCKLES]

Your sister doing better?

Comes home Friday.

The doctors thought
it would take much longer

to bounce back from thallium poisoning,

but they are happy with her progress.

That, and also she won't stop critiquing

her physio's understanding
of anatomy, so...

Sounds like she's back to normal.

So, Mr. Cuevas.

Cause of death is clear.

Blunt force trauma
to the head, neck and chest.

Manner of death, on the other hand,
is trickier to define.

Not natural, not su1c1de,
which leaves us with accident

- or...
- Homicide.

- Robocide, though, right?
- Mm-hmm.

"Cide" meaning act of k*lling,

"homi" meaning by human, whereas...

You think Ocho is responsible.

Almost missed it in the examination,

but I caught it in the X-ray.

Now, this is a bit
of our victim's skull,

cleaned and lit obliquely.

You can see the impact here.

Something hit him hard,

leaving this very distinctive wound.

Now, this is the robot's hand.

You see the manufacturing defect,
this little curve?

ROBY: I'd call that a match.

This robot hit our victim on the head

- very hard.
- RAJAN: Oi.

I have something here.

There's something reflective
in this wound.

Some kind of piece of glass.

I didn't notice any chipped
or cracked glass on Ocho.

Maybe he was struck
by some secondary implement.

A bottle or a drinking glass?

Remember that one time,
with the snow globe?

I don't know what a snow globe's
doing in a robot factory.

Find out where the glass came from.

And I'm gonna get together with Folsom

and try and recreate his att*ck.

[CLICKS LIPS]

I wish he would just
tell us what happened.

But I guess if we want
to find the person responsible,

we're gonna have to figure out

what happened to this man, blow by blow.

[SNIFFLES]

My dad was a really good guy.

I'm sure everybody
who comes in here says that,

but he...

Everyone at his job
said he was really kind.

We'd go to the supermarket, the bank,

and everybody working
there knew him, like,

"Hi, Robert." "How's it going, Robert?"

He got along with everyone, almost.

Almost?

There was this woman at his work.

She's around my age. Her name's Eve?

Her and Dad got into it
pretty bad a couple months ago.

I think she kind of hated him, actually.

Do you know what the fight was about?

He didn't want to tell me,

but I think it had
something to do with a patent.

- Which is weird.
- A patent?

My dad was really good
at putting things together.

But he wasn't like
a real engineer or anything.

He didn't go to college.

I think he got it in his head

that he was contributing
more than he really was.

He was actually pretty stuck on that.

But you don't think
that that's why he...

Right now we don't know.

I hope that he didn't...

whatever it was, you know...
push it and get himself...

I'm sorry, I just...

I'm not ready to not have him
around, you know?

GILL: I can feel it.

This is gonna be the one.

It's gonna float up to that little line,

tell us it's a match
to that tiny shard in the victim's neck.

RAJAN: Okay.
The next one will be the one.

- Totally.
- It better be.

We're running out of glass
from the crime scene.

Unless there's some more
stuff in this vacuum thingy.

If I can figure out how to...

Oh! ...open it. [LAUGHS]

You good?

Are you ready for the next one?

Yeah.

Are you still thinking about Chavez?

No.

Well, I mean, it's just, when,
when I told you about Chavez

reporting to the IAB, you said yeah,

but you said yeah like you already knew.

I did. For a few weeks now.

And that didn't bother you?

[SIGHS]

Is it annoying if I say "Not really"?

Yes.

Well, not really.

Hey, this is really bothering you.

No, it's just weird.

[STAMMERS] We should get back to work.

On the glass?

Okay.

- [DROPS IN LIQUID]
- Yep.

This one for sure.

CHAVEZ: We know your boss is here.

LVPD saw his Bentley pull in


I understand. It's really frustrating.

But I'm afraid I just
don't have him right now.

CHAVEZ: "Frustrating"?

One of his employees
was m*rder*d last night

on the floor of his factory.

Any idea when you will "have him"?

I'm so sorry.

Believe me, we are all still reeling

from Mr. Cuevas's passing.

But all I can say at the moment is,

I don't have him.

What about the woman I spoke to earlier?

Eve.

We have some follow-up
questions to ask her.

Unfortunately, I don't have
her at the moment either.

Oh. You don't even have to look?

- I don't have her.
- Of course you don't "have" her.

'Cause you can't "have" people.

You can have a good time.

You can have a hankering for pancakes.

You can have chlamydia.

Okay. [CHUCKLES NERVOUSLY]

We are happy to wait
until they're ready.

For now could you just
show us to the restroom?

Mm-hmm.

You do know that your job
comes with a badge, right?

This way's faster. And more fun.

Besides, I badge her,
she lets us through.

By the time security
leads us to his office,

he's already out the back door.

Plus it's you and me.

What does that mean?

Well, you, I trust
with something like this.

I love all my CSIs,

but some of them struggle
with keeping a low profile.

Oh, cut 'em some slack.

They didn't all start off
as undercovers.

I did not set out to either.

It was a fast track to detective.

There's actually a whole story to...

Huh.

Yes! Yes!

You see how it happened?

WILLOWS: Truman Thomas.

Let me guess,
this little demonstration...

not what it looks like?

ROBY: Somebody's been busy.

Yes, ma'am.

I've isolated what I think are

the different trails
of impact and castoff.

And I've also gotten started in
on the math you're gonna need

for that adaptive model.

This is a lot, even for you.

Trying to cross every "T"
and dot every "I."

So, uh...

how you doing?

I know that, after what happened,
you don't trust me.

Not like you used to.

Well, you did save
Allie's life last week.

That ought to count
for something, right?

I just want to earn back what we lost.

What I lost.

You know, it's not your trigonometry

or your work ethic that I worry about.

It's my judgment.

RAJAN [ROBOTIC VOICE]: Who is ready

to do the robot?

Hey.

Hey.

Is now a bad time?

No, no, we're just getting
started on the blood spatter.

Well, uh,

we struck out on glass
from the crime scene.

Penny and Beau are sampling
every glass bauble you can imagine,

trying to figure out where that
tiny shard in the wound came from.

So I thought I would, uh...
[SNAPS FINGERS]

come help you guys out.

We could use all the help
we can get, right?

Okay. So, I've color-coded the spatter.

Yellow for the big droplets,

what we would normally expect
for blunt trauma.

And then the blue,
the tiny droplets that had to have come

from something moving really fast.

Question is, how did
the tiny ones get there?

["SUFFER IN SILENCE" BY REZZ PLAYING]

Nope, that's not it. Try something else.

Uh-uh. That angle won't work.

FOLSOM: What about from above?

ROBY: I'm afraid that's not it either.

RAJAN: No, the blood
drops are still too big.

Uh-uh, still not enough force.

No, no, no. We're headed
in the wrong direction.

Based on these readings,

there's no way a person
could punch hard enough

to create blood spatter
droplets this small.

There's no way a person could.

RAJAN: You really think
hecan punch that fast?

We're gonna have to find out.

Sorry, you want
to turn on a k*ller robot?

We're gonna need some help.

You were teaching
that robot to k*ll a man.

Are you trying to tell us
it was a coincidence?

I'm not trying to tell you anything.

- why you were out here with...

I'm not gonna discuss my day.

I have work to do.

High score.

So, how can I help you two ladies?

A man was k*lled
in your factory last night.

Possibly by one of those machines.

We come out here
and we see your employee

demonstrating how it was done.

You think that Eve had something to do
with the death of that worker?

Oh, come on.

That's totally stupid.

Eve's a programmer. That was a...

proof of concept.

To prove that a bot like
Ocho could have done it.

If I didn't know it was totally stupid,

I'd say it sounds like you were hoping

that's what happened.

Well, I would think that was obvious
that that would be optimal.

I'm with you.

I mean, this could be huge.

Huh. She agrees with me.

Oh, the implications
would be staggering, right?

Well, I mean,

fate loves irony. [CHAVEZ CHUCKLES]

For years, I've been warning the world

about the dangers of sentient AI.

And now, if it's finally here...

"Fate loves irony"?
You've been warning us for years?

About what?

The things you've been racing
to build in this very lab?

- A man is dead.
- TRUMAN: Yes.

And that's a terrible tragedy.

But what's done is done.

And wouldn't one human life be worth it

to herald the birth
of an entirely new sentient species?

- That you helped create.
- I mean, not just helped create.

I'm the very reason
the technology exists.

I've long feared AI.

But if a man must shepherd it
into existence,

there's only one man I trust.

CHAVEZ: You know, I wonder
if LVPD, with our legal resources,

could... help you.

- How so?
- CHAVEZ: Well,

if we could prove
in a court of law that your AI,

your creation, acted on its own...

[EXHALES, CHUCKLES]

Yeah, you could open up a few
doors to our investigation.

Let us help you prove
your breakthrough legally.

It's interesting.

I suppose a sort of alliance
could be, uh...

mutually beneficial.

[BUZZING]

GILL: Chavez lied to us to our faces.

I just don't get
how that doesn't bother you.

Well, when I was at Dow,

I got an offer to be on Undercover Boss.

Seriously? You did?

No, not really.
I just thought it'd be cool.

FOLSOM: I didn't even know

CLIFF: Well, uh, you need special tools.

Uh, Thomas is insistent

that only our people
can open up these guys.

The sensors store data in a board inside

Ocho's chest. Uh,

if we pop it open, we can desolder

the memory modules and, if you're lucky,

get some lidar info,
maybe even some videos.

Doubt you'll find a smoking g*n,

but it's worth a sh*t.

so, um, what's next?

We need to know if there's any way that

this thing could move faster.

Is there maybe a limiter

or something with the software?

I guess I'm not totally sure,

but I'm not controlling Ocho
like a remote control car here.

Uh, he uses what's called

"model predictive control."

Um, so I tell him what I want him to do,

and then his learning AI

figures out how it wants to do it.

Wait a minute, so this thing
really is thinking?

I always think we've
capped out the hardware,

then the AI iterates itself,

and develops new behavior that's more

athletic or coordinated.

Ocho and his brothers
are always surprising us.

Is it just me

or does this thing
seem just a little bit more

like the Terminator now?

CLIFF: I mean, I'm not saying
he sped himself up, but...

theoretically...

ROBY: It could've
found an inner strength,

like a mother
lifting a car to save a baby,

only malevolent.

You know what worries me?

We don't know how
to test that empirically.

FINADO: All right, that should do it.

There you go.

It's all yours.

marked rush. You had me
run them through AFIS,

- You got a magnifying glass.

You focus on what you know

Get to it.

Okay, what do we think happened?

- Could be random.
- It doesn't feel random.

Well, I was down in Reconstruction,

and that robot's eyes turned on
right when it happened.

You think there's a chance
that thing flipped the switch

- on the whole building? How?
- ROBY: Not just how,

but why?

That thing is supposed to pick up
screwdrivers and boxes.

It's not supposed to be
a damn James Bond villain.

I don't know how a robot
like Ocho could power off

an entire building,
but it's possible, right?

"When you eliminate the impossible,
whatever remains..."

not saying that it was...

but if it was, its timing
couldn't be better.

Thanks to the power
surge, our best lead...

Ocho's memory module...

has, quite literally, gone up in smoke.

That is not the first time
that's happened.

Yeah, you're talking about
the surge at the factory.

Wiped out all the cameras
just before Robert was k*lled.

Maybe you should head down
to casa de robot,

check out their power system, hmm?

Well, if a human k*ller
is causing these surges,

could be they left something behind.

Let's head down to Reconstruction.

You, me, and Folsom
finish what we started.

Everything looked normal to me.

Ooh, Catherine and I are
headed back to the factory.

You coming with?

No. Max asked me to check out

the power situation here, so, no.

This Chavez thing's really
stuck in your craw, isn't it?

Chavez and I aren't besties,
but we're friends.

Or, at least, I thought we were.

I look back at this last year,
and how much of it was a lie?

I feel like I'm crazy.

Am I crazy?

You are not crazy.

I mean, you are crazy,
but I kind of get it about this.

Well...

nothing works.

I hate to admit defeat,

but I am officially out of ideas.

Well, you had some good ones.
It was a valiant effort.

ROBY: Before you go,

the power surge at the factory
the night of the m*rder,

can you explain that?

They looked at it. Couldn't
figure out what happened.

Out of curiosity, who was
assigned to look into it?

Uh... I think that was Eve.

Yeah, uh,

anyway, I will

let you guys know
if I think of anything.

Thanks, Cliff.

So, I'm open to the idea that

this robot taught itself to hit harder

and faster than we could make it, right?

But if there's no way to test it...

Then we have to rule out
everything else.

ROBY: So then let's
get creative, shall we?

What are other possible ways could

account for this unusual blood spatter?

What if the robot's only responsible

for the medium velocity spatter,

and the high velocity spatter

was caused by some other source?

Like an implement of some kind.

Like a club or a

thin pipe or a...

Something like that
might explain the glass.

ROBY: There you go.

Pretty good at-bat,
but it's not fast enough.

Turn the hips, squash the bug
with the back foot.

- Squash the bug?
- [LAUGHS]Yeah, turn them hips.

Yeah, I do 'em all, baby.

Your coworker's just down here.

Really appreciate you showing us
down here personally.

Yeah, well, my people have

But I guess you can get a warrant, so

what choice is there?

What happened to letting us
help you prove

your robot really is a k*ller?

I don't think it's possible.

Yet.

Quite the about-face. I'd say.

What's changed, Mr. Thomas?

WILLOWS: I bet your people

came to the same
conclusions that we did:

that it's physically impossible
for that machine

to have struck the k*lling blow.

CHAVEZ: That'd be bad news, huh?

All the downsides
of a wrongful death lawsuit.

WILLOWS: None of the upsides

of birthing new AI life.

Whatever.

My mind is preoccupied

with far more interesting
things right now.

More interesting than one of
your employees being m*rder*d?

Gee,

I got to see what's on that phone.

Look, one of my teams, MKD-1...

Eve's team... they suffered

a mechanical issue that
set them back a few months.

Now, I'm not ready to say
that it was sabotage, but..

[PHONE BUZZING]

Look, I'm needed elsewhere. Sabrina.

Sabrina can help you.

Excuse me.

You know, you expect billionaires

to be rude, standoffish weirdoes,

but I got to admit,
that guy is a charmer.

[CHAVEZ CHUCKLES] CATHERINE: The grid?

- That way?
- Yes, it is.

He told us there were
some files set aside for me.

Do you have them?

Of course. This way, Detective.

Hey.

Hey.

Splash of almond milk?

[LAUGHS] Beau.

You're really getting to know me.

Thanks.

[ROBOTIC VOICE]: You may not
always enjoy me, but I am your friend.

[LAUGHS]

Ha, ha, ha, ha. [NORMAL CHUCKLE]

RAJAN: That thing would be way cuter

if its face wasn't a nightmare mask.

The face isn't what bothers me.
What you got?

The glass from the crime scene
remains a mystery.

None of these was a match?
Is that a bong?

We tried everything.

And it gets worse.

I tested the compressive strength

of the glass from the wounds, it's way

too brittle to do too much damage,

even if swung at those speeds.

Well, we're having better luck.
I'm getting close to matching

the speed needed to account
for the high-velocity spatter.

- Close?
- No, but not close enough.

Folsom is swinging like
a walk-on at a D2 school.

And unless our k*ller was,
like, ready to go pro,

- I'm kind of skeptical.
- I don't think there's many

power-hitting first basemen
at the robot factory.

- No, just a huge pack of nerds.
- Hey, hey, glass houses.

Now I'm kind of thinking
maybe a flexible implement?

Like what? Like a whip?

Maybe a whip? Is a whip crazy?

ROBY: With those wound patterns?

- Uh...
- Golf club, maybe?

Big graphite driver? They flex.

But the hardest hit
to our victim was here.

The skull. And that impact was

an exact match to Ocho's arm and hand.

How is that possible?

Well, I only got close 'cause
this bat is long, like a lever.

How could Ocho's arm
ever travel that fast?

Ocho's arm could move that fast
if it wasn't attached to Ocho.

We appreciate you heading down

- so quickly, David.
- DAVID: Of course.

Just don't know
how my dad's tools will help.

Do you need his fingerprints, or...?

Well, not his fingerprints,

but something almost as unique.

The other day you said
sometimes your dad

took his work home with him?

- That's right.
- To do that...

he needed this.

DAVID: Driver bit?

Not just any driver bit.

MKD uses proprietary tools.

This is like a key.

To open a very specific lock.

♪ ♪

- This is it.
- Mm-hmm.

The joints, look at this.

Yep. That's our whip.

Would you stop swinging
that damn thing, please?

- Yeah.
- So that thing, swung hard enough,

could reach a velocity

sufficient to create

that unique blood spatter pattern.

FOLSOM: What are
the chances that our k*ller

b*at Mr. Cuevas with this arm

- as a w*apon of convenience...
- ROBY: Mm-hmm.

FOLSOM: and then reattached it
to the body in order to frame

Ocho for his crime?

- Guys?
- ROBY: What'd you got there?

David?

Did your dad wear eyeglasses
or contact lenses?

No, he didn't.

Thank you, David.

FOLSOM: What you got, Al?

Polymer-hydrogel. Contact lens.

And odds are, if it doesn't
belong to our victim...

Then Ocho just gave us a little
sample of DNA from our k*ller.

[KNOCKS ON GLASS]

Heard we're about to have
a solve on the Cuevas case.

What's DNA telling you?

Nothing yet.

Should be a minute.

Hmm.

Did I forget your birthday?

Is that it?

Happy birthday, Penny.

[CHUCKLES]

Whenever it was.

Can we be cool?

You lied to me.

You lied to all of us.

You reported on us to IAB for a year.

That was...

It was my job.

To report back the truth and...

and the truth I reported was

that everyone in the Vegas
Crime Lab was hardworking,

and smart and-and totally honest.

Okay. Great. Thanks for your help.

I know everyone here just assumed

that CSI was in the clear
after Hodges and Anson Wix.

But not Max.

You know, she knew what I knew.

That the powers that be
still had their doubts

until I proved to them that
everything was on the up-and-up.

Look, I'm sure you're right.

Okay? I'm sure everything
you're saying is right.

It wasn't that you did it that's crappy.

It's that you could do it.

I just, I thought it was one way
and it's another way.

Well, and what way was that?

I thought we were friends.

That's up to you.

I did lie.

A lot. I'll give you
all that about the past.

But we are on the same side, Penny.

So maybe just keep
an eye on me in the future.

Notice how the way I work
makes your job easier.

Maybe you'll like me better
as a coworker.

[COMPUTER BEEPS]

CHAVEZ: What is it?

Did we get 'em?

I know who the k*ller is.

The DNA on the k*ller's
contact is a match.

To Cliff.

What?

But he's been here all day.

Truman Thomas did mention
he thought there'd

been some sabotage of Eve's
team. She's Cliff's rival,

I gather. Maybe, maybe
Robert saw something?

We don't have to guess.
We can ask him. Put an ATL

out on him and send a couple squad cars

out to that damn robot factory.

[PHONE RINGING]

CHAVEZ: There's no way he's
listening to us, right?

He has microphones,
but he's powered off.

Hey, Cliff.

Director Roby, hi.

Uh, just checking in.

I heard you called looking
for the proprietary bit

to detach Ocho's arm?

I can grab one

and-and head down to you if you'd like.

Well, that'd be great.

I mean, the team's ready now,

- if you want to head on down.
- CLIFF: Sure.

Just curious, why do you need

to take off the arm?

You got to understand,
Robert wasn't even

supposed to be on that side
of the building.

He, he did his rounds
out of order that night.

[WHISPERS]: Go.

[TIRES SCREECHING, HORN HONKING]

It's okay. Just stay with me, okay?

CLIFF: Robert, he saw what I was doing.

The MKD-1 prototype.

Robert saw.

- I'm gonna...
- Cliff?

[CAR CRASHING, PHONE BEEPS OFF]

Cliff?

Find him.

[SIRENS WAILING][INDISTINCT RADIO CHATTER]

Hey.

Is that Cliff?

Dead.

Penny thinks k*lled on impact.

Among other weird things,
the car's pretty new,

but the airbag didn't deploy.

Thank you.

Only yaw marks. No deceleration.

He didn't hit the brakes.

Maybe the brakes were out.

We're not thinking the AI
somehow did this, are we?

Uh... Hey, old camera.

We'll run it to confirm,
but what do you want to bet...

GILL: That's the source of
the mystery glass on our victim.

Can't wait to see what's on the film.

Well, you're gonna have to.
Wait, I mean.

If there were any film in here,
it's long gone.

The CSIs tell me your help
made the difference,

bringing those tools when you did.

It made a difference to me, too.

I mean, I knew he had stuff
in his garage, but...

going in there and digging through it,

finding his tools.

I loved my dad, but...

I didn't take him
seriously enough as an engineer.

You mentioned your dad thought
he was unfairly

left off a patent
for the robot's hand and arm?

I've been going through MKD's files.

Your dad was a huge part of the project.

This is a patent lawyer.

Friend of a friend, owes me a favor.

If you'd like...

she'll fight for your dad's
claim on contingency.

Thank you.

For the truth, I guess.

About my dad, too.

ROBY: I hear you wanted to talk to me?

So you were right.

As always. I stepped back.

- Looked at the bigger picture.
- Mm-hmm.

Our suspect had been
running from the police

while high on methamphetamine.

When he attempted to open the window,

he squeezed hard enough
to deform his fingerprints.

Manually adjusted for that,
and we got him.

Come on, Zoey. Now come here.

You remember this next time
you want to farm out

your job to something
with an on/off switch, okay?

Mm-hmm. Get out of my office.

- Good job.
- Zoey.

- Hey.
- Boss.

How are you doing?

So, uh,
you're checking in on me now, huh?

I just know this case
was weighing on you.

And I wanted to touch base.

I hope you'll rest
a little easier now that it's closed.

I mean, we got justice.

Guess you'd call that
a partial confession, huh?

You think Cliff knew more than he shared
before he, uh... you know.

It's more than that, it's just, I...

I see this man

just lying on the floor dying,

with machines moving
and working all around him.

Well, we've only got good machines here.

The ones that help
you catch the bad guys.

Don't get me wrong.
I like my EZ-2 and my GCMS, but I...

I do prefer my people.

Flawed though they may be.

Good night, boss.

Hey, you want me

- to get this thing out of here?
- Uh, no.

We'll send him back when
the case is officially closed.

Okay?

All right.

For now, you stay put.
