- Previously on
"The Irrational"...

- Nearly all
irrational behavior

is driven by our emotions.

It's nice to meet you, Izzy.

I had up to fifth-degree burns
on 60% of me.

- Got a couple sixes.

- I survived. You will too.

Your scars won't have
to feel like this.

You can come through this
with a good life.

- Do you know
Professor Rachel Myers?

- Yeah.
- She offered me a position.

- I know.
What happened was crazy.

- But it's always crazy.

I have to tell you something,

and I don't want you to be
upset or hurt.

- You're taking the job
with Rachel Myers.

- You know what this means.
You're number one now.

You'll have to help
the professor

choose a number two.

[Allen Stone's "Sunny Days]

- * She's the wave
that I am riding *

* The thunder
to my lightning *

* She's the one and only cake
that I am icing *

* Oh, something's
coming over me *

[doorbell chiming]

* I'm obsessing *

- I'll be right there.

- * Head over feet *

* You know life *

* It ain't always *

- Need access
to my backyard again?

[gunshots]

[thudding]

[dramatic music]

* *

[light music]

* *

- This place is ridiculous.

It doesn't even feel
like a real school.

It's actually fun.

- [laughs] Thanks, Izzy.

Learning doesn't
have to be boring.

It all depends on the approach.

- I can't believe how fast
they redid this place.

It's impressive.

- I could say
the same thing about you.

Look how much progress you've
made in less than a year.

- Thanks.

The doctors say I should be
ready for laser therapy soon.

It's supposed to help
with the scarring

and mobility issues too.

- That's great news.

- From what I've read,
laser therapy works

on old scars too.

- [chuckles]

- Ever thought about it
for yourself?

- I have not.

- I can send you the studies.

- Well...

how about I show you
the cafeteria?

* *

[knocking]

- Sorry to bother you.

How was your visit with Izzy?

- She's doing great.

Something tells me
she's not the one

I should be worried about
right now.

- I think I finally found

the perfect person
for our team.

He went to Stanford Undergrad,
Northwestern Grad School.

Field of study is
psychobiology,

which I thought was a fun,
new perspective for our group.

And he's in the lounge
right now.

- It sounds great,
but why are you doing

your nervous pacing thing?

- [chuckles] It's Simon Wylton.

And I'm worried about hiring
him because he's a Wylton,

and I'm worried
about not hiring him

because he's a Wylton.

- What part of him
being a Wylton

actually factored
into your decision?

- None.

The truth is I saw
his last name was Wylton.

I didn't realize
till our interview

that it was that Wylton.

- Rizwan, you know
what this department needs.

If you think he's
the right person for the job,

let's give him
a chance to prove it.

If there's any blowback,
I can handle it.

Let's not keep him waiting.

Simon, good to see you.

It's been too long.

- Alec--
um, Professor Mercer,

it's great to see you too.

I'm kind of geeked out
to be here.

This was always the most fun
spot on campus.

- Well, I've got
some good news.

You're hired--starting now.

- What? Really?

- We do things a little
differently around here.

You join the team
for a week trial period,

learn the ropes,
get acclimated.

And then after a week,
we'll evaluate.

- That sounds amazing.

I, um--I won't let you down.

[phone ringing]

Me? Uh, OK. [chuckles]

Uh, hi.

Um, Professor Mercer's phone.

Right, and is that Marisa
with one S or two?

- I--I got it.
- Oh.

- Thanks.
- Sure.

- Hey.

[suspenseful music]

[indistinct chatter]

[helicopter rotors thrumming]

* *

Hey.
- Hey.

The victim is Serena Barton
from Channel 4.

- I guess that explains
all of this.

- Yep.
It's not every day that

the face of the 11:00 news
is the 11:00 news.

- What happened?

- Looks like a knock-knock
burglary gone wrong.

But there were
two similar murders

in two different states
last week.

This makes three.
- You think they're linked?

- I'm not big on coincidences,

especially when
they cross state lines.

It's been a nightmare
at the Bureau.

They bumped our SAC
to the head of Intelligence

but haven't found us
new leadership.

With no one steering the ship,

I could use
all the help I can get.

- Any guesses who your
new boss is gonna be?

- Knowing the FBI,
it'll probably be

the safest, most boring choice.

- Wow.

- Detective Brown,
meet Alec Mercer.

He's consulting on the case.

- Hi.
- Eric Dent.

Works with
Secure View Sentries.

They provide security for a lot
of the houses in the area.

He was first on scene
after the murder.

- Yeah, one of our clients
heard gunshots next door,

hit the panic button.

I followed protocol.

I didn't see anyone
suspicious in the area,

but the front door
to this house was ajar.

That's how I found the body.

- Eric gave us backend access
to Serena's doorbell camera.

Forensics is analyzing it now.

- Thanks, Eric.
I can walk you out.

- Yeah, sure.

- We know if anything
was stolen yet?

- A few of the drawers
were rummaged through.

Brown talk to Serena's husband.

He said the only items missing

were an amethyst geode

and a high-end pair
of sneakers.

- A rock and some sneakers?

- Mm-hmm.

- It looks like our robber
wasn't very good at robbing.

- Which leads me
to believe that

the robbery was just a pretext.

The whole point
of a knock-knock burglary

is to make sure that
someone is not home

so that you can clean house
without confrontation.

In all three cases,

our killer was knocking
to make sure someone was home.

- So he could kill them?

- Exactly.
And not only that.

The killer smashed her veneers,
same as the other two.

- You think
this is a serial killer?

- It has all
the earmarks of one.

- Except one.

Serial killers target people
they think won't be missed

because they have one goal,
to keep on killing.

Why would a serial killer
target a high-profile victim?

[suspenseful music]

[doorbell rings]

- Everything OK?
Can I help--

[gunshots]

* *

.

- Who's going to talk
to the reporters?

- I guess I'm going
to have to do it.

- Here she comes.
- Excuse me.

- We are still assessing

whether this murder is related
to the previous murders.

- Are you saying
this is a serial killer?

- We don't know that yet.

- What about
the people at home?

Should we be scared?

- We should take the same
precautions we always do.

- Is it definitely
a city worker?

Who is he targeting?

- I understand that
you're worried.

There are a lot of unknowns.

But this is my community too,

and you can trust me
when I say that

we are taking
every single measure possible

to find this individual
and bring them to justice.

* *

- Now exhale slowly
to the count of five.

[soft music]

Now repeat.

Meditative breathing
not only soothes the soul,

but helps with critical
thinking and productivity.

And one final round.

[singing bowl ringing]

* *

Great job, tribe.

- Professor Myers,
I just have to say,

I love our morning meditation.

Before this, I could barely
sit still for five seconds.

- Me neither. [laughs]

Turns out I just had to find
the right practice.

- And the right place.
- Mm.

- The last few months
have been incredible,

but I'm ready to take on
more responsibilities.

Is there anything that
I can take off your plate?

- You're a worker bee.

And that's commendable,
but trust the process.

Let me set the pace.

- Of course. You're right.

[chuckles]

- Hey, Phoebe.
- Hey, Ava.

- I hope this doesn't
sound weird,

but I overheard
your convo with Rachel.

And I know she doesn't really
encourage collaboration,

but I was wondering if

you could look at a paper
that I'm writing.

- Of course.
I'd love to help.

- Yeah? Cool.

- Send it my way.
I'll take a look.

- OK.

- A serial killer?

For real?
- I don't know.

Real serial killers--

the ones sensationalized
by the media, anyway--

they're extremely rare
nowadays.

There's cameras everywhere,

and it's hard
not to get caught.

Their whole goal is
not to get caught.

- But this guy goes
to houses with cameras.

I mean, why take that risk?

- Hey.
- Hi.

- Hey.

Saw you on the news earlier.

Gotta say,
you did your thing, sis.

You were great.

- Well, it didn't feel great.

Public speaking is
really not my thing.

- You could have fooled us.

- I might have eased the crowd,

but people need answers.

They want to know that
the next knock on their door

isn't gonna be a serial killer,
and I can't promise that.

I'm gonna check in with Brown.
[phone chimes]

See if they found anything else
in forensics.

- I--I know.

- Damn.

Remind me to never
send you a text again.

- [sighs]
Izzy sent some articles.

Uh, she's thinking
about getting

the scar revision procedures.

She thought
I might be interested.

- Are you?

- [sighs] With what time?

If I'm not here,

I'm doing my research
at Wylton,

and I can't take a year off.

- Mm-hmm.

Is that what you tell Izzy?

- Look, with Izzy,
it's different.

She's got the rest
of her life ahead of her

and the chance to change it.

She can afford
to take a year off.

The risks are low.
The benefits are high.

With me, on the other hand--

- I talked to Brown.

He thinks
they caught the killer.

- His name is Carlos Perez.

He's a construction worker,

builds sewer lines
for the city.

Worked in Serena Barton's
neighborhood.

- Giving him easy access.

- I got an eyewitness that said
she saw a construction worker

run out of Serena's
right after the gunshots.

She ID'd Perez this morning.

- You use a lineup?
- Of course.

- That neighborhood is busy
with construction.

There could have been at least
25 men with the same outfit.

- Yeah, but this one did
five years for burglary.

And check his socials.

He has some sort of
resentment toward the rich.

- OK.

A few tweets
hating on the rich.

Do you have any
physical evidence, DNA or--

- We're still combing
through everything.

But in my experience,
if it walks like a duck--

- It doesn't necessarily
make it a duck.

It could be negativity bias,
which causes people

to judge their
present situations

based on their past
negative experiences.

- Mm.

You saying I'm bad at my job?

- I--
- [laughs]

- You were right
to call in Perez,

but according to this,

he hasn't committed a crime
in over 10 years.

- That we know of.

Look, I've seen this
a million times.

Criminals,
they fall off the wagon,

and they go back to the life.

- Still, to jump
from some burglaries in 2010

to multiple homicides now
is a huge leap.

- I told you,
I have an eyewitness.

- This eyewitness, how sure
is she about what she saw?

- 100%.

She didn't second-guess
herself once.

- You mind if we talk to Perez?

- He's in holding.

Be right back.

- 100% sure.

- That's exactly the problem.

- What are you thinking?

- I'll tell you what.

How about you talk to Carlos?

- What you gonna do?

- An experiment.

[tense music]

- I did a lot of awful things
I'm not proud of.

And my world got really small.

But I'm 11 years
clean and sober

ever since I went in.

- What was your method?

B&E, smash and grab?

Reseller?

- I was high out of my mind.

There wasn't a system.

I was just surviving, you know?

- Are these your socials?

- OK, that was over a year ago.

I don't even use
that account anymore.

Trust me, if you had my job,

you'd want to blow off
some steam once in a while too.

But I had nothing to do
with that murder.

- Where were you
on Wednesday afternoon then?

- Across town,
eating lunch in Nottoway Park.

Look, I'm no saint.

I did a lot of messed up stuff
when I was using.

But I didn't do this.

* *

[suspenseful music]

- Quick pop quiz.

Out of all the 12 cards,
how many spades are there?

- Three.
- Three.

- Are you sure about that?

Look closely.

There are five in total.

1, 2, 3, 4, 5.

We don't count
the two red spades,

only the three black.

Our mind sees
what it expects to see.

- Hey, I saw you
hitting on my girlfriend.

Don't lie.
- I would never do that.

Please just chill out!
- No way!

I want you to admit it.

I want you to admit it
right now,

or you're gonna regret it.

- Well--hey, someone stop him.

He took my phone!

* *

- So now that I got your hearts
racing a little bit--

the crime you just saw,

I'm gonna ask you
some questions about it.

[indistinct chatter]

OK, get ready
to lock in your answers.

What type of bag
was Rizwan holding?

Was it a backpack,
a duffel bag, or a laptop bag?

Go.

* *

Remember the guy that
was yelling at Rizwan?

What color was his shirt?

Was it yellow, green, or blue?

* *

OK, last one.

What kind of hat was
the thief wearing?

This one's open-ended.

* *

Now, from zero to 100%,

how sure are you
of your answers?

* *

Wow, so some of you
were 100% sure.

Thanks to a hidden camera,

we can see
what it actually was.

It was a laptop bag,
a green shirt,

and that last question was
a trick one.

He wasn't wearing a hat.

So let's see the results.

Only 15% of you got
all three answers right.

Under stress,
people are often wrong.

Even so,
some are quick to judge,

and they will say that
they are 100% sure.

And someone who is 100% sure
can only be sure of one thing,

that they are overconfident.

Stress can affect how
our short-term memories

are encoded into
our long-term ones.

Almost moments after
a stressful event happens,

we start forgetting.

That's why witness stress

leads to less accurate
eyewitness accounts.

- I know you don't want
to hear this,

but there is not enough
evidence to convict Carlos.

- There is now.

Some new evidence
came in today.

Carlos said he wasn't
in the neighborhood

the day of
Serena Barton's murder.

- Right.

- Eyewitnesses make mistakes,

but cameras don't.

[tense music]

.

- OK, I was
in the neighborhood,

but I swear
I didn't kill anyone.

- Carlos,
I told my friend Alec here

that I'm inclined
to believe you,

but we are the only ones
on your side.

If you don't tell us the truth,

you could be convicted
for four murders.

- OK. OK, I lied.

But I was there to see a woman.

[tense music]

Her husband's a cop.

If he knew, he'd kill me.

- What's her name?

- Bree Garland.

We met about a year ago

at a bar called
the Bronze Rabbit.

I knew she was married,

but she said
she was over with him,

that it wasn't a real marriage,
you know, that kind of thing.

- You still seeing each other?

- On and off.

After a few months,
she broke it off.

But then a--a few weeks later,
she called me.

The last time we hooked up was

the day the newscaster
was killed.

After that,
she called it off again.

- It's called limerence.

It can seem like love,
but it's more like obsession.

People can get a high from it.

The problem is,
when limerence wanes,

so does their interest.

- If you're telling us
the truth,

Bree could alibi you, right?

- Please, if her husband
finds out, he'll kill me.

I'd rather be in prison.

- So we talk to her
where we won't find him.

- It's a marriage in name only.

I'm leaving him.

- Why do I have the feeling

you've said that line before?

Carlos Perez.

- Oh.

That's what this is about.

- He says that he was with you

the day
Serena Barton was murdered.

- Are you his lawyer?

- I'm kind of lawyer-adjacent.

- If I alibi him in court,

my husband will kill me,
for real.

- Mm.

You could sign an affidavit
in private.

- I'll think about it.

- When people have trouble
making decisions,

the default position is
do nothing, rather than act.

But in this case,
inaction is a very real action.

[tense music]

Carlos will go to prison

for four murders
he didn't commit

for the rest of his life.

The real killer will
keep on killing people.

Can you live with that?

* *

- Hey, Mom.

Yeah, I just got off.

Yeah, I know, I know.

Dentist appointment
tomorrow morning.

Yeah, the one by the old
karate studio, right?

[chuckles] Don't worry.

I did not forget.

OK, love you.

[gunshots]

[thudding]

- Scott? Scott!

Honey, please answer me.

Oh, gosh. Scott, please.

You're scaring me!

[police radio chatter]

[indistinct chatter]

[siren wailing]

- I appreciate the ride, Simon,

but you don't have to come
to the crime scene.

- No, I--I want to.
- You're sure?

- I might be able to help.

I did my, uh--my thesis

on the, uh, psychobiology
of psychopaths.

I've never seen
a serial killer IRL, though.

- IRL. I hope you never do.

- Hey, you brought Simon.

Isn't he new?

- He wants to help.

- Well, the CSI techs are

still working
the crime scene.

Ballistics match
the other murders

and the teeth-kicking ritual.

- One of the common brain
abnormalities in serial killers

is a reduction
in size and activity,

the prefrontal cortex.

- Causes them to be more
obsessive-compulsive.

- Er, exactly.

Yeah, they, uh,
they live for a pattern.

Shooting a blue-collar kid in
the middle of the street is...

[clears throat]
It's off pattern

if you've been
shooting the rich

on their front doorsteps.

[gulps] So, in my opinion...

[clears throat] I'm sorry.

[clears throat]

[retching, coughing]

- That's a normal
biochemic reaction

to seeing a murder victim
up close.

He has a good point, though.

Serial killers don't change
their MO.

The MO is the point.

- So you're still not convinced
it's a serial killer?

- At least not
the traditional kind.

There's a reason he's choosing
the victims he's choosing.

We just need
to figure out what it is.

[crickets chirping]

[keys clacking]

[knocking]

- I was just emailing you.

Your paper is great.

- Really?
- Really.

You have a lot
of interesting findings.

- OK, good. Yeah.

I have been working on it
for almost a year.

- Just--uh, just a few small
comments and one thought.

The title doesn't
really do it justice.

- What?

You don't like
"Improving Idiosyncratic Fit

Across a Multitude
of Chat Clients"?

- Maybe something more fun.

AI's role is to help us
find the perfect product,

so maybe, um,

a play on finding
the perfect fit.

Um, how about
"The Glass Slipper"?

- Oh.

Yes, I love that.

Uh, hey, chatbot,
find me my glass slipper.

- Yes, that's it.
That's the one.

- That's so good.

[soft music]

- * I'm always lurking
with people *

* Looking for a... *

[rattling]

- Hey.
- Hey.

Oh, I'm starving.

What in the "Magic:
The Gathering" is going on?

- I'm trying to find a pattern
among our victims.

[sighs]

This shade of blue
stimulates creativity,

and the cards are a way
of tricking my mind

into finding connections,

like our brain does
with playing cards,

like suits or numbers.

- Or tarot arcana.

- OK.

- That's pretty clever,
but in my experience,

pattern finding is much easier
on a full stomach.

- Nice.
- [laughs]

So I've been reading up
on those laser treatments

that Izzy mentioned.

It seems legit.

You know, that new stuff
that they're doing

is really exciting.

- Yeah.

Izzy seems really
hopeful about it.

- I'm not talking about Izzy.

You remember when you tried
to teach me how to swim?

I was seven, and the only thing
I hated more than raisins

was the deep end of the pool.

And it terrified me,
but you showed me

that it wasn't so scary
and that--

- Ah.

I know what you're getting at,

but it's not the same thing.

So please, just leave it.

* *

- Ugh!

Why?

They put cilantro
on my fried rice.

- Cilantro city here too.

- This is gonna taste
like soap.

- You can blame OR6A2 for that.

- OR-who?

- OR6A2.

It's our cilantro-hating gene.

Wait a second.

[suspenseful music]

- Mm-mm.

You're doing the whole
"Beautiful Mind" thing again.

* *

- It's their genes.

Our killer's signature was
to smash their teeth in.

And it turns out nearly
all of our victims

have had extensive dental work.

- You think their bad teeth
is a genetic condition,

like our cilantro gene?

- Maybe.

[phone keys clicking]

- Amelogenesis imperfecta.

- Amelogenesis
imperfecta.

- It causes abnormal
enamel formation,

and it is hereditary.

- Our victims, I think
they're somehow related.

.

- OK, thanks, Rizwan.
Let me know.

Simon didn't show up
for work this morning.

- Is it too early
for I told you so?

- I'm not ready to give up
on the kid just yet.

- Fine.

How about you were right?

All five victims were
siblings--

donor siblings, to be exact,

conceived at
a donor clinic in DC,

which leads us
to sperm donor number 3462.

- Number 3462 cleans up nicely.

- Steve Thomas.

Apparently he invented
something called Map Moves,

paved the way
for all the navigation apps

that we use today.

- It still doesn't answer
the central question.

Why would anyone want
these siblings dead?

- Maybe donor dad
has some answers.

[suspenseful music]

- Hi. Angelo Petrillo.

- I hear you're
Steve's attorney.

How long have you known him?

- Well, we go way back,
Yale Undergrad.

Just a couple of
scrappy scholarship kids

trying to fit in.

But Steve was different.

He was a machine.

He took twice the number of
credits required in a semester.

Mm, sperm donations paid
for his meal plan.

- What happened to him?

- Well, he never stopped
being that machine.

He worked seven days a week
with only three hours of sleep.

Eventually, his lifestyle
caught up to him.

He had a stroke
and then another.

That's when I got the call
saying he made me

executor of his estate.

Asked me to divide his fortune
among his biological children.

- Giving you access
to a secret list of donor kids,

the same list that the killer
is using to target his victims.

- Hey, legally,
I'm not allowed access

to any of that information
until Steve passes.

Those records are sealed
until then.

- What about their inheritance?
Is it substantial?

- Yeah, like I said, I don't
know how many kids he has,

but either way,

$50 million isn't exactly
chump change.

- No, it isn't, but it's
definitely motive for murder.

- What we're dealing with here
is similar to a tontine.

- A ton-who?

- Back in World War I,

soldiers would pool
their money,

and the ones that survived
the war would split the pot.

The more deaths, the bigger
the share for the survivors.

- OK, that's bleak.

Steve unknowingly created
a tontine amongst his children.

- They weren't raised together,

so they were strangers
to one another.

- You run the numbers.

$50 million split
evenly among, say,

20 kids, that's $2.5 million.

- And with each murder,
the share increases.

Now, with five kids dead,

the killer would get
a million more dollars.

- That's a geometric
progression.

Each death becomes more
valuable than the last.

- A huge incentive for
someone wanting to win big.

[phone buzzing]

It's the donor clinic.

They've tracked down
all the donor kids.

- One of them is
probably the next victim.

- Not only that.

One of them is
probably the killer.

[suspenseful music]

- Phoebe? Hey.

- I was in the neighborhood.

Thought I'd say hi.

- How's Professor Myers?

She keeping you busy?

- Uh, yeah.

I mean, it's super low-key,

but it's good
for my stress levels.

We, uh, do daily meditations.

- Seriously?

You once told me
your definition of hell

was doing nothing
for 10 minutes.

- Hmm.

I'm working my way up
to 3 minutes.

[chuckle]

So it's about the intention.

[papers rustling]

Are you OK?

- Uh, of course.

- Then why did you mark this
student's name as incorrect?

- [sighs] Honestly,

I hired a new RA
on a trial basis.

- OK.

- He called in sick today,
his third day.

- Maybe he is sick.

- Professor said he freaked out
at the crime scene.

- Professor said that?

- OK, not those exact words,
but today he's a no-show.

I'm putting together profiles
of the donor's siblings.

- Donor siblings?

- It's a new case we're on.

And I'm grading
last week's papers

and prepping the professor's
lecture for tomorrow--alone.

- That's a lot to do alone.

- [sighs]

I met with dozens
of qualified candidates.

I could have chosen
anyone else.

I think I messed up,
picked the wrong one.

- OK.

You must have chosen this guy
for a reason, right?

You weighed the pros and cons?

- Yes, I did
everything you said.

- Well, that's the purpose
of a trial week, right?

See if he's a good fit for you,
if you're a good fit for him.

Even if the answer is no,
that's OK.

Maybe you just need
to trust the process.

[upbeat music]

It will be OK, Rizwan.

- Look at you all Zen.

The meditation is
totally working.

* *

- As for your other problem,
how about I grade the papers,

you work the case,

and we organize
the lecture together?

- Really?
- Of course.

I'm on my lunch break.

That gives us an hour.

We've done far more in less.

* *

- Wait.
- You're saying someone is--

- Trying to kill me?

- And you think I did this?

- I was in the hospital.

- I was at my kid's
soccer practice.

- In Paris.

- Screw where I was!

You dragged us in here

and make us answer
a million questions,

but what are you doing
to protect us?

- Everyone, including
this guy with an attitude,

has an alibi for at least
one of the murders.

- Which means they're all
potential targets, right?

- I'm going to notify Brown.

Keep them under
police protection.

- What?

- It took us forever
to get this list of siblings,

and that was with a warrant
signed by a judge.

How did our killer
get their hands on it?

[suspenseful music]

- [chuckles] Genetic testing.

Sites like Two DNA Chains
help the FBI

find killers through
their living relatives.

- You think our killer is using
one of these sites

to track down their siblings?

- Or they could have used
all of them.

I mean, that's what I would do.

The siblings were scattered
through several sites,

but one person showed up
related to all of them.

- Did you get a name?

- A username.

It's pretty generic.

Ed33.

- You have to upload
your DNA to these sites,

right, to get a match?

Which means all we have to do
is get a warrant,

and then we have
our suspect's DNA.

.

- Simon, you're here.

- Yeah.

Um, sorry about earlier.

I'm feeling a lot better
now, though.

- No worries.

There, uh, anything
you want to talk about?

- No, I'm good.
Thanks.

I just want to focus
on the case.

Any news?

- We've been tasked
with getting DNA samples

from all the donor siblings

who aren't on any
of the genetic sites,

see if their DNA matches up
with our suspect's.

So far, they've all consented.

- Which is good and bad news,
right?

I mean, if I were the killer,

I probably wouldn't consent
to a DNA swab.

I'm betting
we don't get a match.

- [sighs]
It just doesn't track.

Only an heir to Steve's fortune

would want their siblings
dead, right?

So it has to be one
of the donor siblings we met.

[suspenseful music]

- What if we're all getting
so caught up

in the high-tech biology,
we're missing a simple fact?

Steve was once a young
biological machine

with sexual drives.

- You're right.

Steve was a tech disruptor,
super risk prone, right?

He could have brought
that lack of caution

to his own sex life,
fathered an illegitimate son.

- Or it was just the '80s.

- [laughs] True.

I'll call the professor.

[soft music]

* *

- You were asking
for more to do.

I've got the perfect
assignment.

- Really?
- Yeah.

I've been working
on a grant proposal,

so I need you to proof it
and suggest edits.

- I'd be happy to.

- Wonderful.

- It's for a study
in how AI can improve

the consumer experience,

particularly
with online shopping.

Take a look.

See for yourself.

The title's pretty cute, right?

The Glass Slipper
is a nice touch.

- It's great.

* *

- Detective,
I got your message.

You said there was
a new development?

- I was working protection
detail for one of the siblings,

Jack Polanski.

I parked here
a few houses down,

and that's when I saw him.

- Are you sure it was him?

- He was wearing the vest
and everything.

I mean, he walked up
to the house,

was about to ring the doorbell,
and then he stopped.

Something spooked him.

- You get a look at his face?
- I couldn't see.

By the time I got close enough,

the guy jumped into his
service truck and took off.

Don't worry. I got--
I got a photo of his plate.

We're running the plates now,
but it'll take a second.

- Some kind of technician?

- Can't quite make out
the initials.

- That damaged back bumper
looks familiar.

It was at Serena's house,

the--the SVS
patrol officer we met.

- Eric Dent.
- You think it was him?

- Quick way to find out.

[phone rings]

- Hey, Alec, what's up?

- Can you look up
an Eric Dent, D-E-N-T,

from Secure View Sentries?

- Try and find a picture
of him smiling.

- I got you.

[keys clacking]

Hmm.

He doesn't smile
in any of his pics.

Let me try his work profile.

[keys clacking]

[suspenseful music]

Damn.

I see why he's so angry.

Those teeth.

- It's the amelogenesis
imperfecta.

I'll call you back.

Eric may not be
a donor sibling,

but he is a sibling.

- And just as much an heir
as the others.

- But if he made me, he'll go
underground, disappear.

- He's come too far
to bail now.

Something called goal gradient
shows us that

when people get close
to the finish line,

it's nearly impossible
for them to stop.

It's irrational,
but Eric's invested.

He's got to end this.

And if I'm right...
[sighs]

He's got one more person
to kill.

[tense music]

- Security cameras
are still on.

- I just tried Steve's lawyer.

It went to voicemail.

Kylie did a deep dive on Eric.

His mother was a waitress.

She had one-night stand
with Steve

decades ago.

She died last year--cancer.

- Eric's grief could be
fueling his resentment.

- It's not about money anymore.

- We need to protect Steve.

Alec, stay here.

SWAT should be arriving soon.

If you see anything, call me.

Don't try to Jedi mind-trick
this guy.

Let's check the house.

[suspenseful music]

* *

[knocking]

* *

[clicking]

Clear.

- [gasps]

- FBI.

We're just checking
to make sure everything is OK.

- Power went out.

Mr. Thomas's machines.

What happened?
- We're not sure.

Why didn't you answer the door?

- I had my headphones on.

He doesn't get
too many visitors.

Battery backup won't last
more than an hour.

- We need to get him
to a hospital.

It's safer there.
- I'll call an ambulance.

Hopefully it gets here
before Eric does.

- He probably shorted
the power.

Chances are he's already here.

[suspenseful music]

* *

- It's over, Eric.

You're too late.

The FBI is already inside.

Wait, wait.

- Like you care?

You don't know me.

- I do know you.

I know that your mother
struggled to take care of you,

but she did the best she could.

- My mother?

My mom would be here right now
if she had the money,

all the money that
he could have given her!

- She would.

It's not fair
what you went through.

I'm guessing she told you about
your father before she died.

- I went to him.

I told him who I was.

He said he'd take care of me,
just like he was

taking care of the rest
of the test tube babies,

as if we were the same.

It's not right!

- It's not right.

That's when you looked them up,
and you saw

how much better
they were living.

It hurt you.
- He owes me!

The only thing I wanted
from that man is what I'm due!

- I understand, Eric,

but after
the first few murders,

you knew you weren't
getting that money.

But you couldn't stop.

You resented them,
and you hated him.

But you're not just
your father's son.

You're your mother's too.

You were there for her.

You put her life
before your own.

Now the question is,
who are you gonna be?

The person who lives
in the shadow of their father

or the person your mother
knew and loved?

And will you live
long enough to prove it?

[suspenseful music]

* *

- Eric Dent,
you're under arrest.

.

[elevator bell dings]

[light music]

* *

- Hey, Kylie, what's up?

- Now, I probably shouldn't
be telling you this,

but I can't keep it to myself.

Guess who is being tapped to be
the head of your department.

- I hope it's not Ned
in Narcotics.

- No.

It's you.

* *

- How do--how do you know that?

- Uh, let's just say...

upgrading all the FBI's
computers to a new email system

has its perks.

You're the new boss, Boss.

Honestly, nobody deserves it
more than you.

[elevator bell dings]

[indistinct chatter
playing on speaker]

[knocking]

- Come in.

- Uh, you're busy.

I'll come back.

- No, no, no, no, no,
it's fine.

[beeping]

[chiming, powering down]

People say that noise is bad,

but studies have found that
noise on this level

increases alertness
to the brain

and boosts performance,

which is why people write
in coffee shops.

- Or it's because
the caffeine stimulates

dopamine release,
which improves motivation

and increases
divergent thinking.

- That's another influence.

But you didn't come here
to talk about coffee.

- No.

Um, today's the last day
of my seven-day trial.

Before you make any decision,
I just wanted to be honest.

The other morning when I said
that I was sick,

I wasn't.

I lied.

- The crime scene.

- It was a lot.

And I wasn't sure
I'd be able to do this job,

let alone do it right.

- Crime scenes are upsetting.

I'd be more worried
if it didn't bother you,

considering
your family's history

and your brother's accident.

- It wasn't about that.

- Look, you and I both know
what it's like

to have the worst thing
that's ever happened to us

replayed over and over again
on the evening news.

- OK, maybe it was
a little about that.

But still, I was dishonest.

I didn't show up for you.

I left Rizwan in the lurch.

It was wrong.

- [laughs]

I guess Detective Brown
isn't the only one

with a negativity bias.

- What do you mean?

- You're so worried
about the things you did wrong

that you're forgetting about
all the things you did right.

You pulled off your performance
for that experiment.

You brought valuable
insight to the crime scene.

And best of all,

you helped us track down
Eric Dent.

Simon, that was
your first week.

And I know you can do the job,
but the question is,

do you want to?

- I do.

Very much.

I swear.

- Well, then, young one...

welcome to the team.

- * There are no answers *

* There are only questions *

- I was talking to Simon
about negativity bias

when I realized I was guilty
of the same thing.

I was so scared
of reliving my past,

being back in that hospital,

that I wasn't giving myself
a fair shot at the future.

You were right.

I'm not too busy
to consider laser therapy.

I was just lost
in my own negativity bias.

- But for good reason.

I mean, it's not like
being in the hospital was

a walk in the park.

Those surgeries,
they were hard and painful.

So call it bias if you want,
but I get it.

- Still, I know better now.

- You do.

Look, if you want to get
the treatments, I support you.

And if you don't,
that's cool too.

You know I got your back
no matter what.

I just don't want you
to miss out on life

because of fear.

And you would want
the same for me.

- In a heartbeat.

[knocking]

- You order something else?

- Guess who I invited over.

- Hey.

- Heard there was an order
for an extra side of cilantro.

I'm just kidding.
I brought dessert.

[laughter]

- Thank you. Come on in.

- You must be the famous Izzy.

I've heard so much about you.

- Same.

It's so good
to finally meet you.

- I thought Izzy could
come around for dinner

to help me weigh the pros
and cons of the treatment.

- Now, that's
what I like to hear.

- I'm very lucky to have
this one as a sister.

- [chuckles]

- I know.

[laughter]

Now let's eat.

- All right.

- [vocalizing]
