Previously on "The Rookie"...

HARPER: An arm was found
near Silverlake Reservoir

- this morning.
- I honestly don't know

what instrument was used to remove it.

That arm is related to
a case in Arizona.

A coroner there found an arm

that was severed with
that same mystery tool,

and both were done while
the victim was still alive.

That's horrible.

And it means we're looking
at a possible serial k*ller.

- Should we be calling the feds?
- Yeah, I already did.

I'm so happy for you.

Really? You're okay that
I'm putting down roots here

Of course.

I love youuuu-ur neighborhood.

It's so eclectic and...

You just dropped the L-b*mb

That tile is original.

What?

You're so spontaneous.

- Come on.
- [CELLPHONE VIBRATING]

Um... no.

- What?
- Seriously?

I have to go into work.

Uh, this is...
You're in the middle of a move.

- Garza gave you the day off.
- I know.

And he would not bug me
unless it was serious.

Movers are coming in literally an hour.

They're not gonna know
where to put any of this stuff.

Oh, but you will.

Is this a test?

%.

And if you love me, you'll ace it.

Mm-hmm.

Thank you.

Okay.

Here you go.

One more kiss.

- Mm.
- Bye.

GARZA: Okay, listen up.

During a recent m*rder investigation,

LAPD uncovered what could
possibly be a serial k*ller

operating right here in Los Angeles.

- Please.
- We discovered a severed arm

that was not linked to our m*rder.

It had a unique cut.

Unique how?

It was too clean.

There were no striations
from a commercial blade,

no burn marks from an industrial torch.

We matched that unique cut
to a severed leg

from a Black female found in Arizona.

That's when we called in Agent Clark.

And that's when I called in Antoinette.

I haven't been able to fully
examine the limbs yet,

but it's clear that both were
severed using a waterjet cutter.

The waterjet uses an industrial pump

that propels water faster
than the speed of sound.

It can cut through metal like butter.

It is not a common tool,
which means our k*ller needed

both access and technical expertise.

Like a specialized factory worker.

Right. Or high-end
construction contractors

often use waterjets to cut glass,

granite, marble, porcelain.

Does that mean you had access to one?

Yeah. I have a friend
who lends me his whenever I...

I just made myself a suspect, didn't I?

- Yeah.
- [LAUGHTER]

Swear it wasn't me.

They all say that. Don't worry, Carter.

I'm keeping my eyes on this one.

Were you able to I. D. The victims?

Not yet. Both limbs were
compromised from exposure,

so DNA typing is in process.

My next step is to examine the arm

that just landed in my lab.

- Good.
- Would you mind if I watched?

Sure.

- Happy to have you.
- Sweet.

Most serial murderers target
a certain type of victim.

On the face of it, the fact
that our current victims

are different genders and races...

It suggests that there's a-another
factor that connects them.

Could it be opportunity k*lling?

Possible. But not probable.

Okay. I want everyone
bringing their A-game today.

Understood?

Let's stop this guy
before he takes another victim.

Let's move. Thank you for your help.

Please reach out
if you need anything else.

Of course.

So, how's the remodel design going?

Slowly, sorry.

Protecting and serving
has been a little hectic.

Tell me about it.

I still say you should hire
a professional architect.

I say don't dim your shine.

Everything you've shown me
so far looks great.

Okay, well, I will send you
some revised drawings.

And good luck with
your psychopath of the day.

- Thanks, handsome.
- Bye.

So what's the first step?

A physical examination...
Which I've already done.

Aside from the amputation area,

the condition of the limb is consistent

with the two-week
timeline since removal.

So while the victim was still alive?

Yes.

And the Arizona victim's leg

was removed approximately
two weeks before that.

That means our psycho k*ller
is due to k*ll again soon.

Possibly. But careful
jumping to conclusions

at this early stage.

Science is about facts, not supposition.

And two instances
don't constitute a pattern.

- Is that an infrared camera?
- [CAMERA SHUTTER CLICKING]

Very good.

Now that I've examined the limb
with the naked eye,

it's time to see
what I can't see naturally.

[DRAMATIC MUSIC PLAYS]

What's that?

That is how we're going to I. D.
Our victim.

Sebastian Milner... Thirty-two years old

at the time of his death,
out on parole for armed robbery.

His wife, Sheriece, reported
him missing two weeks ago.

SIMON: Thank you
for coming in, Sheriece.

SHERIECE: Did you find Sebastian?

Whatever it costs
to bail him out, I'll pay.

Honey, I am sorry to tell you this.

But your husband has been m*rder*d.

I knew he didn't leave me.
My family can suck it.

Wait. Uh, what?

I've been defending Sebastian
ever since we became penpals

when he was in prison.

They all said he was using me,
but, uh-uh, we fell in love.

Yeah. Um, when was
the last time you saw him?

days ago.

He went out to the liquor store
at midnight to get a six-pack.

Never came home.

Before his disappearance,
did you notice anything strange,

like phone calls where people hang up,

or was anyone following you guys?

No.

He always said
the only way he would leave me

was if God took him.

Right. Well, God didn't do this.

But if you can remember
what liquor store he went to,

maybe we can find out who did.

Do you remember seeing this guy
two weeks ago?

[SIGHS] Negative.

Do you know how many people
come in and out of my store every day?

Plenty, but this guy's a m*rder victim.

So look again.

[SIREN WAILING IN DISTANCE]

Answer's the same. Don't recall.

BRENDON: Don't recall, or won't recall?

Maybe it'll jog your memory
if we check behind the counter,

see if you're stocking something...

Okay, okay.

Guy tried to rob me.
Pointed a . in my face.

Then out of nowhere,

some dude shows up in a mask
and tases him.

So you witnessed a m*rder?

- Whoa, slow down.
- [BELL JINGLES]

I didn't witness nothing.
I hit the deck.

When I got up, both guys were gone.

Why didn't you call the police?

I get robbed every other week.
Cops don't do squat.

Dude with the mask saved my life.

Ain't no way
I was dropping a dime on him.

Well, now you are.

Get us your surveillance tapes.

[SIGHS]

So our serial k*ller
is a masked vigilante?

[CELLPHONE BEEPS]

How's the decorating going?

Come on. A man of your skills

and you have it up against the wall.

- Yeah.
- BRENDON: Atlas. Hey, buddy.

Hey, Brendon. Um, Laura,
when are you coming back?

Maybe it's better if you did this.

I can't. I'm on a serial.

Hello. My specialty.

- Mine too.

by getting my house squared away.

So glad I'm not dating you.

SEBASTIAN: Money! Now!

- LARRY: Okay, okay, okay.
- SEBASTIAN: Money!

I got it.

[TASER CRACKLING]

What the hell kind of taser is that?

It's a picana.

It's basically a cattle prod
used for t*rture.

It delivers twice the voltage
of a stun g*n.

Our suspect thinks he's Batman.

Last I checked, the caped crusader

doesn't cut criminals
into tiny, little pieces...

Well, unless we're talking
about Frank Miller's Batman.

You know, we just got a report
that a teenager was att*cked last night

by a guy with a big-ass Kn*fe.

Only to be saved by a masked man
with a cattle prod.

An impatient boss
breathing down my neck.

Come on, Matt. You know this takes time,

finding a serial k*ller.

And we hardly have anything to go on.

We don't even know
how he picks his victims.

It's just... It can't be a coincidence

that he's ending up at crime scenes

at the exact right moment
to save people.

It's not. Because
he's not there to save them.

He's there to stop the attacker.

Most serial K*llers
stalk their victims, right?

Well, odds are
he's doing the same thing.

Right. But if he's looking for
violent criminals,

- how does he target them?
- The obvious assumption

is that he's law enforcement, right?

Well, let's not jump to that
conclusion just yet, Brendon.

DNA results came in on both victims.

We couldn't find a match
on the female victim.

But we did find a match
between her and Sebastian.

Our victims are related?

Yes. They had the same
biological father.

Okay, boss. According to
Sebastian's widow,

he never knew
who his biological father was.

His mother purchased donor sperm

from a fertility clinic
at Saint Stephen's.

We need to find out if our female victim

was a product of the same donor.

Or if her mama was knocking boots

with our mystery donor in real life.

Hopefully, the doctor at Saint Stephen's

can give us the answer.

Patient records are confidential.

Yes, sir. But we're hunting
a serial k*ller who m*rder*d the child

of at least one of your old patients.

My clinic has delivered
thousands of kids

through IVF over the decades,

so odds are some of them
have met untimely ends.

But we may be able to keep someone else

from being m*rder*d.
And your files could really help us.

Unless there's another reason

you don't want us looking
at your records?

No.

Doctor, let me remind you

that lying to the FBI is a crime.

Okay. A couple months ago,

someone hacked into our system.

Accessed patient records
from thirty-plus years ago,

then wiped them from the servers.

Please tell us you have hard copies
of those files somewhere.

[DOOR CREAKS, WATER DRIPPING]

You know who would love
to go through these boxes?

[ELECTRICITY BUZZING]

Oh-ho-ho-ho, I just did an escape room

that looked exactly like this.

But this place smells
way more authentic.

I didn't mean to drag you into this.

It's fine. Fertility records
are highly technical

with an emphasis on anonymity.

Elena will need my help
deciphering them.

CARTER: Our first priority
is to identify

Sebastian's donor father...
Use him to get the identities

of any other children from his samples.

They might be the k*ller's next targets.

We won't let you down.

No doubt. Happy hunting.

So... how do you want to start?

By getting organized.

Hopefully, they'll get an answer

before our unsub strikes again.

I'd put money on those two.

Wh... Hold up, Carter.

Daddy?

W-What are you doing here?
What's going on?

It is nothing.

No, no, really.

I-I just got a little dizzy.
I did not want to worry you.

Doctor, should I be worried?

His dizziness could be caused
by any number of things,

most of them fairly benign.

- See?
- But due to his age,

we need to run some tests,
just to be sure.

So we'd like to keep him overnight.

CUTTY: Of course you do.

Damn capitalist medical system
just wants my money.

Knock it off. You got good insurance.

You're gonna stay here
as long as they tell you to.

And guess what else.

I'm gonna be right here with you.

- Absolutely not.
- Why?

Because it's just
a lot of waiting around.

And tell me you do not have something

more important going on.

Look, I'll call you if anything changes.

And I will call with regular updates.

Thank you, Doctor.

You, next time, call me
before you head to the E. R.

[MUTTERS] Y... Mm-hmm.

Why do I know that name?

about a bunch of strangers who exist

'cause I got touchy-feely

Then why the hell did you drive

all the way out here
to ask me about this?

Someone's k*lling off
your kids, one by one.

[LAUGHS]

Now, that's more interesting.

And I can see why
you didn't want to share that.

Do you have any idea
who could be behind this?

I mean, if it was me,
I'd, uh, pay a visit

to the families of my victims.

After what I did to their loved ones...

I'd want revenge, too.

- That's the last box.
- Okay.

That means we have seven
children from Briggs' samples.

All born between and .

We already knew about Sebastian Milner.

And Edwina Davis here matches

our African-American Jane Doe.

Reported missing a month ago.

And the others? Are they local?

We should get them protection.

I haven't been able to track
down everyone's whereabouts,

but, this one... Maggie Whitlock...

- Lives in Grenada Hills.

Uh... hey, Theo, I noticed

Would you mind showing me your trains?

I'm totally into those.

Is that okay?

BRENDON: Given who his father is,

you really think it's a coincidence

that Sebastian Milner
turned into a violent criminal?

There's no way to tell.

Sebastian's childhood is
a litany of abuse and neglect.

In and of itself,
that's causal for psychopathy.

And DNA from a serial k*ller
didn't do anything

to our other victim, Edwina Davis,

other than make her

[SUSPENSEFUL MUSIC PLAYS]

What kind of danger?

Someone appears to be targeting

Were you aware that
your mother used a sperm donor?

No. My parents never told me
that they used a donor.

And now you're telling me

- [CLEARLY] Very good.

You're one of the kids...

And you're taking out your siblings.

Yes.

And you're gonna help me
finish what I started.

ATLAS: There we go.

Now we can play Call of Duty in K.

I can't believe Laura has an Xbox.

She didn't, till now.
I got it as a housewarming gift.

I.E., you bought it for yourself.

What's taking Laura so long?

I don't know. Didn't she say the store

- was just down the street?
- Yeah.

[SUSPENSEFUL MUSIC PLAYS]

Car's still here.

ATLAS: That's...

♪

[CELLPHONE RINGING]

- You hear that?
- BRENDON: Yeah.

[RINGING CONTINUES]

♪

Oh, no.

Okay. Why did he take her?

Not sure. But we might have
an idea of who he is.

Now is not the time for suspense, so...

He's one of Briggs' biological children.

The files that were stolen were sealed.

Except for his offspring.
Any one of them

could have looked
into their biological father.

That's not a motive
to m*rder their siblings.

No, but it is a lead.

So three of the kids
are either dead or assumed so.

Who is left?

Uh, Maggie Whitlock seems unlikely.

Roman Griffith is in Vancouver.

No, he's not.

That's the man I saw
in Maggie's backyard.

I'm positive.

Okay. We need a deep dive
on Roman Griffith.

And we need it yesterday. Let's go.

Alright. Let's do this.

Mm.

[SIGHS] Okay.

Clearly you're a serial m*rder*r.

With the pathology that entails.

Clearly.

When I spoke with you on the phone,

I wouldn't call you a monster.

And that resonated with you.

[HEAT LAMP BUZZING]

You think you're acting
for a righteous cause.

Um, uh, a rational one.

See, I knew you had the juice.

Exactly, exactly.

You know, for a minute, I thought

that you were targeting
your siblings out of jealousy.

You alone would carry
your father's bloodline forward.

But...

No, that's not right.

You're ashamed of it.

You think it made you what you are.

When I was growing up,

my parents were...

kind to me.

They... They never stopped loving me,

uh, despite how I was.

And we... We tried everything.

Doctors, therapists, priests, meds.

Nothing worked.

Nothing would relieve
this pressure in my head,

nothing except v*olence.

- m*rder?
- ROMAN: No. I wanted to.

But I found ways to stop myself.

And then I found out
who my real father was.

And that he was the worst version of me.

And then I dug a little deeper

and found out
that he had other children.

Violent children...

- No, not all of them.
- ROMAN: How can you be so sure?

I mean, yes, Sebastian
and Chet... they...

They are out and proud
about their cruelty.

[GROANS]

But you don't know what goes on
behind the scenes

- with the others.
- LAURA: So, you thought

that you were doing the world a favor

by taking your siblings out of it?

- Yes, yes.
- But that...

That doesn't explain
why you want me here.

I'm not one of your siblings.

And I'm not telling you
anything that you don't know.

It's the boy.

- Maggie's son?
- Mm-hmm. Yeah, he has the DNA.

The only sane thing
I could do was take him out.

But I couldn't do that.

Why?

Some might call that a conscience.

Don't mock me.

Don't you dare mock me!

I have been agonizing over this.

I just got off the phone with LAPD...

Roman's apartment is empty.
But there is a BOLO out.

I am not gonna hold my breath.

So what have we pulled on our subject?

Roman Griffith, raised
in Claremont by two professors.

Discipline issues growing up,
but nothing serious.

No criminal record.

He wound up in a trade school,
became a machinist.

He's worked for a decade plus

at various aerospace manufacturers.

Explains how he knows how to use
a waterjet cutter.

Yes, but not how he had access to one.

Those machines cost hundreds
of thousands of dollars.

Wait, wait, Boss.

Two of the factories
Roman worked at closed

in the past six months.

Blue Sphere Aviation
and Descent Aerospace.

And... both of these

are in quiet, industrial areas.

Carter, Simone, you're with me.
I'm gonna contact SWAT,

have them meet us at Blue Sphere.

Brendon, Atlas, you take Descent.

Let's move. We are running out of time.

Why don't you get this?!

You spend your life
tracking people like me.

Like my father.
And... And like this boy.

Think of... of the...
The victims he will hurt and...

And the... the families
that will grieve.

Sorry, just to be clear,
you... you want a pep talk?

To k*ll a six year old.

To stop a m*rder*r before he strikes.

It is no different than what you do.

Maggie's son might have had
some of the DNA as Briggs.

And as you.

But, Roman...

You k*ll because you want to.

And there is no amount of rationalizing

that's gonna change that.

I sent her home with Atlas.

She's hurting, but she's gonna be okay.

The rest of the siblings?

Safe and sound.

But even with Roman gone,
I don't think it's a bad idea

to keep tabs on the rest
of the Briggs clan.

For their safety? Or the world's?

Well, one thing I learned
by having children

is that there are some traits

you can't do anything about.

No amount of nurturing will change it.

My daughter Billie came
into this world stubborn

and opinionated
and has yet to see the light.

Yeah, that's definitely in her DNA.

work with you on this case.

It was fun.

I should be thanking you.

Your attention to detail

is quite impressive.

I learned more cool stuff
in the last two days

than in the past two years.

I'm constantly learning myself.

It's the best part of the job.
