(dance music playing)

(tires squealing)

COLBY:
Victim's Michelle Kim.

She used to look like that.

What's the deal?
Why can't LAPD handle this?

Uh, she used to work for
the Chinese Consulate.

You know how those guys are --

15 minutes after they
find out she's dead,

they'll have her
apartment cleared out.

What did she do
for the consulate?

Interpreter.

Witnesses?

Yeah. It's a hit and run.

Some say Tahoe,
some say Explorer.

No way to know for sure.

There's got to be at least
a dozen bars in the area --

figure a D-U-I hits her,
panics, takes off.

No skid marks.

Nope.

Any damage to these cars?

No.

Lucky drunk.

Yeah, tell her that.

Mmm.

You know, they say
there's nothing sexier

than a man who knows
how to cook.

Well, what do you say,
you agree?

I don't know.

I like guys who are
good at math.

Aw. Well, actually I'm using
differential geometry

to perfect
the chocolate chip cookie.

That's right.

What, is this in case the whole
math genius thing doesn't work out?

- It's for Senior Ditch Day.
- Hmm.

You mean Senior Beach Day.

Yeah, when they're away,
the underclassmen will play.

Remember, last year,
they ransacked my office.

Yeah, so this year...

This year, I leave a peace
offering for the hungry natives.

Hmm, needs bigger chips.

So...
(clears throat)

I guess congratulations
are in order.

For?

It's a bit controversial,
but I like it.

I mean, Larry used

a non-standard analysis
instead of the conventional

Borel approach in treating
the singularities.

Can I... just... (stammers)

So Larry published an article...

on zero point energy and quan...

and quantum cosmology.

You didn't know?

Well, I thought he would have
asked you to collaborate.

Me, too.

Coroner found paint chips
under her skin.

Color traces back
to the Ford Motor Company.

They have a model yet?

Either Explorer or a Jaguar.

Better notify the locals.

If that SUV was stolen,

it's gonna be headed straight
to a chop shop.

Looks like Michelle Kim
moved back and forth

between here and
China growing up.

We got a file on her?

Yeah, this is Granger,
FBI, for Jackson.

No, but we have on her father.

Okay, just have him
return it, thank you.

Former Chinese diplomat.

Retired in '97.

FBI Counter Intelligence ran
a background check on her

when she moved back
into the country in '03.

Counter Intelligence?
Why were they looking at her?

I don't know.

Whoa, whoa, wait a second.
Scroll back down there.

Right there.
That background check

was filed by an old Army buddy
of mine.

- Dwayne Carter.
- Yeah.

Carter and I did a tour
together in Afghanistan.

You guys still tight?

I've called him a few times,
but he hasn't been around.

(exhales)

That guy saved my ass.

No way.

Yeah, we were in this Humvee
together,

got hit by an RPG and the thing
just exploded into flames.

I got trapped, had this piece of
metal just wrapped around my arm.

Thought for sure
my ticket was punched.

Dwayne, he just... jumped in,
man, ripped me out of there

and the dumb bastard, he got
third-degree burns on his hand.

Sounds like the guy to talk to.

DON:
Hey, what are you doing here?

Oh, I'm just gathering some information
for a paper that Larry's working on.

Hey, you know, you guys have
direct access through NASA's firewall.

That's right.
Big Brother's always watching.

Hey, is this a new case?

Yeah, it's a hit and run,
but I don't know,

I'm thinking it's looking
like something more.

Something more like what?

Well, like it's intentional.

Okay, you want me
to take a look at it?

No, that's all right.
Don't worry about it.

Because, you know, I-I... I can
factor in steady motion regimes --

you know, body stiffness
coefficients,

and not to mention, you know,
subtle body undulations

generated
by the ground-reaction force.

You got me there.
Go for it.

Because, you know, was she walking,
was she standing still?

- I don't know.
- How fast was she moving?

Once you have that data,

these impact marks
can tell you a whole lot.

- This is no problem for me to work...
- Knock yourself out.

I'll have an answer for you
as soon as I can.

You're the one who's always
saying you're overworked.

Hey. How'd it go
at Kim's place?

I spoke to a couple
of the neighbors.

She was quiet, kept to
herself, no boyfriend.

What, you don't buy it?

She's 24 years old.

Her last stop was one of
the hottest nightclubs in L.A.

I have my doubts.

Bartender remembers her getting
a call right before she left.

- Oh, yeah? Did it trace anywhere?
- Didn't.

Call came
from a prepaid cell phone.

Techs just lifted Kim's online
bank account records.

Got over a hundred grand
in all-cash deposits.

Well, the Chinese pay their
interpreters really well.

We got untraceable cell phones,

cash deposits.

What was this girl into?

Since when is the FBI interested
in zero point energy?

Huh? Uh...

Are you checking
Larry's work, Charlie?

I'm just looking --
just taking a look at it.

Did he ask you to do that?

No, no.

What he's done
is fairly impressive.

Oh, "fairly impressive."

Well, you know what I mean.

No.

What do you mean?

Nothing. It has, it has
great potential.

Yeah, but it needs
your assistance.

To be honest with you...
yeah.

Yes.
Mm-hmm.

Charlie, did you ever think that
maybe Larry doesn't want you...

Why wouldn't Larry want my help?

I don't know, but he sure
didn't ask for it, did he?

(elevator bell dings)

PFC Granger, you son of a gun!

(laughing)

- Man.
- What's up?

I practically had to put you
under surveillance to find you.

Yeah, if I was easy to locate,

I wouldn't be in Counter
Intelligence now, would I?

What's up?

Well, I caught this case --
Michelle Kim --

worked for the Chinese.

Yeah, they said somebody
was coming up to talk to me,

so I took a look at my
report -- wasn't much.

Any reason you guys were
looking into her to begin with?

Immigration flagged her.

She entered the country
with two passports,

parents both Chinese nationals.

Post 9-11. Thought was,

we had to know what she'd
been up to on the mainland.

And?

She'd been in
Beijing at university;

she came back to take a job

with the Chinese Consulate
as an interpreter.

Everything seemed
on the up and up.

Why? You got
something different?

She died last night.

- Died?
- Yeah. Hit and run.

Maybe more. That's why
I want to talk to you.

Yeah, I don't know.

Uh, I'll ask around.

See what I can dig up.

How you doing?

Adjusting. You?

Yeah, the same, I guess.

Never really goes away, does it?

No, never does.

Al right, you catch something,
give me a call, all right?

Absolutely.

Come here! Come here!

(laughing)

- It's great to see you.
- You, too.

(clears throat)

Ah, Charles.

Say, did you know that
an Oort cloud has a mass

somewhere between five and a
hundred times that of the Earth?

Oort cloud? Cloud
that spits out comets?

Oh, yeah.
Thousands of comets.

- You know, I had, I had no idea.
- Yeah.

So, I've, uh, come by here to
congratulate you on your paper.

Well, that was nothing.

Nothing. Well, what you did,

analyzing the effective weight of
zero point energy in a nonstandard way,

well, that-that could lead
to a solution

for the cosmological
constant problem,

- right?
- Yeah.

Well, I mean, The Uncertainty
Principle of Quantum Mechanics

does say that there must
be some virtual mass, so...

- I'm sorry, I'm running late here.
- Oh, I'm, I'm curious.

Um, who collaborated with you
on the math?

Uh, Brian Stromsborg.

- Oh, Stromsborg's good.
- Yeah, he is.

- He is good.
- Yeah, he's good.

Uh, now, I'm sensing that

there might be something more
involved here than well wishes.

Oh... did you forget
where my office was?

No! No!

Stromsborg has so much
experience in this field.

Yeah, I know, I know.

Yeah, but...?

I'm so used to you
coming to see me.

Perhaps I was getting
a little too used to it myself.

Well, Larry, you know, I hope
I've never made you feel like...

No, absolutely not.

No, I just, I feel of late

just a need to do some
branching out, that's all.

Branching out?

Yeah, well, I'm maybe like a comet
trying to break out of its orbit, uh...

find my own escape trajectory,

just come into my own entity,
I don't know.

I'm so sorry, I'm running late,

but, Charles,
I think I just need

to stretch myself a little,
that's all.

Pure and simple.

I've been cleared by my
ambassador to cooperate in any way.

I've also notified Miss
Kim's parents in Beijing.

You can imagine how difficult
a call that was to make.

I hope you expressed
our sympathies.

To have a child taken from you
at such great distance...

But I suppose a traffic accident
can occur anywhere in the world.

Well, we're not so sure
it was an accident.

I don't understand.

- Well, her job was an interpreter?
- That's right.

Any reason she'd have large sums
of cash in her bank account?

Her personal finances
wouldn't be something

I would have
any knowledge about.

So that would be a "no"?

I'm afraid I didn't really
know her very well.

Well, we'd like to take a look at
a list of people she worked with.

I'll speak with the ambassador,
see what I can do.

Thanks.
Appreciate that.

DAVID: What'd the Consulate
General have to say?

That he knew her less
and less as we stood there.

Well, either he's telling
the truth

or the Chinese have
a very liberal hiring policy.

Why?

Credit card has a bunch
of charges to nightspots,

lingerie boutiques

and the occasional adult store.

Which totally contradicts
what the neighbors told me.

Maybe you should run those
through LAPD Vice, Narco...

You know, we're not even sure
this girl was actually murdered yet.

Um, yeah, actually, we are,

As promised, I do have an answer
on whether or not this was an accident.

I thought you had class.

I do. I have lunch and I...
oh, and dinner.

Look, you guys got, like,
sandwiches around here?

- We'll order out for you.
- A nice turkey thing...?

What do you got?

All right, I tried using
a steady-motion algorithm

to try to determine the motion of
your victim at the point of impact,

but my results
were inconclusive.

- But you persevered.
- I did, I did.

You know,
I imagined her walking,

the motion of her feet,

and then it occurred to me --
curtate cycloid.

Oh, curtate cycloid.

- C.C.
- Right, of course.

Think of someone's, uh,
someone's stride

like the Moon orbiting
around the Earth.

As the Moon moves
around the Earth

and the Earth moves
around the Sun,

the Moon traces out a
curtate cycloid curve in space.

In essence, creating a circle
within a bigger circle.

Now, when you walk,
the heel orbiting backward

then forward past the knee,

creates the same pattern
of circles.

Now, from there, I could
probabilistically determine

the leg motion of your victim
at the point of impact.

And that probabilistically
helps us how?

Well, the marks on her legs
that the vehicle's lights made,

- they're high.
- High?

Yeah, the bumper of the vehicle

was rising on impact.

So what, you're saying
it was accelerating?

Which means this wasn't
an accident.

Oh, no.

Whatcha say, Megan?

Morning.

So, Washington wants us to
handle this on a local level.

How are we doing
on that girl's account?

Not very good. All the deposits
were made in cash

just below the ten grand
reporting minimum.

Yeah? What about Colby's friend?

Uh, Dwayne Carter

said that Kim's background check
was just routine.

A 24-year-old interpreter with
that kind of money ain't routine.

ERT found this access card

during a daylight sweep
of the crime scene.

Kim's prints are all over it

and it does not belong
to the Consulate.

Or her apartment.

I used a key found in her purse
when I went the other night.

- Huh...
- We got ERT running it down right now.

Hey, you guys should have
a look at this.

Techs found something
interesting on Michelle's laptop.

Megan said you
guys got something.

Hey. Yeah.

DAVID:
Michelle Kim's computer.

Seems like she had a thing
for Internet porn sites.

Um, did she save any of the
images from this website?

Oh, yeah, she's downloaded
quite a few images.

Why? What?

Remember that image of the little
girl we found hidden in the photograph?

Right, the child porn case.

This is very similar.

It's only a lot more
sophisticated.

This picture is really thousands
of pixels reproduced as squares.

Now could you please zoom in
on this portion of the photograph?

WOMAN:
Okay.

That's great.

All right, now remove
some of these squares

and you can still see the photo.

However, a coded message
can easily be hidden

within this missing information.

Yeah, and?

Well, you know those tests they
give people for colorblindness,

the green dots?

To someone who's
truly colorblind,

all they see
is a bunch of green dots,

but to a person
with perfect vision,

the same exact image reveals
a hidden picture.

So you think you can crack it?

Uh, look, if there's
a message in here,

yeah, then I should be able
to find it.

Yeah, it's a pass card
for the building garage.

Something happen?

You recognize this girl?

15-C.

She had an apartment here?

Yeah. Had?
What's going on here?

She was killed in an accident.

Oh, wow.

That's horrible.

You know how long
she lived here?

Two years, give or take.

She live alone or with someone?

Uh, alone, I think.

I'd see her come in maybe
one, two nights a week.

You guys keep the tapes
to that camera?

It's all digital.

The footage gets online
to a database somewhere

for insurance or something.

MEGAN: So, Kim maintained
a second apartment?

DAVID: Yeah, under an alias.
We checked it out.

There's no food in the fridge,
no cable hookups.

What do you think?
A meeting place?

The lobby has security cameras.

Colby's checking out
the footage right now.

LARRY:
You know, what amazes me here

is that they're hiding
their messages

using the very same
encryption programs

that the privacy groups
hired us to develop.

Back when I was real little,

I heard that the KGB and the CIA

used to send these encoded
messages via shortwave radio.

- I thought I was the only one.
- Oh, no, you and me both.

Yeah, I'd be listening
to these people talking

in these languages
I couldn't possibly understand.

I was imagining their operatives
in Paris and Germany.

I even tried sending my own
secret messages in response.

I never thought
about doing that.

Well, the police came
to my house.

The police came?

Yeah, it was some FCC violation.

I think they were police.

You know, that reminds me
of that time that we rewired

the P.A. system at Princeton.

Listen, I have to say
it was refreshing to see

your sense of humor that time.

It really was. Up till then,
I was a little concerned

that your natural intensity
might well be your undoing.

It wasn't just about IQs.

Our working together?

No, no, no. I knew your sense
of analysis suited my own.

You're making it sound
like, like that's changed.

Charles, let's face it.

Your passion has taken you
down many new roads:

your work with Don,

your convergence theory...

(clears throat):
My program's got something here.

Hey, look in the eyebrow.

I think those are numbers.

My algorithm was able to
find an image embedded in,

in this region here.

I e-mailed a JPEG to your techs.

They stripped away
the extraneous squares,

which then revealed a series
of letters and numbers.

MEGAN:
Two letters and nine digits;

can't be a phone number.

But it could be
an international banking number.

It's definitely
an offshore account.

Cyprus.
Check it out.

First two letters: C-Y.
That's the country code.

Now, this next file
is very interesting.

This is one that Kim
posted of herself.

I gave it to your guys
to isolate, as well.

DAVID: It looks like
a Chinese character.

DON: Yeah. Enhance that?
Enhance that?

Okay.

Two names.

"Terry Evans," uh,

and "Richard Freeman."

She file-shared the photograph
from a chat room,

but you know there's no way

to trace who might have
downloaded it, so...

Evans and Freeman were federal
witnesses scheduled

to testify against a
guy named Jason Ming

until they were murdered.

DAVID:
Double tap. That's center mass.

This is not just a murder,
it's a hit.

Ming was arrested four months
ago for selling laser gyroscopes

to North Korea
for a Chinese contact.

So the next time the North
Koreans fire a missile,

maybe it hits North America
and not the ocean.

Ming posted a $3 million bail.

A week later the two witnesses
against him were dead.

You know, these two witnesses'
names were in a sealed indictment.

That's a paper file.

So someone physically had to
get that info and give it to Kim.

Only people with access to a sealed
indictment are federal prosecutors.

MEGAN:
And federal agents.

Which means there's a mole
in the Department of Justice,

and if the Chinese have
someone in the DOJ...

Then they can get
to any witness they want...

any case they want.

Hey.

Man, Granger, you scared
the crap out of me.

Michelle Kim --

the last time you saw her
was two years ago?

I already told you that.

Yeah, tell me again.

It's boot camp.

They train you
to put your shades on your back

when you're approaching
a target.

I guess old habits die hard.

I should bust your ass right now
for lying to me!

She approached me

after I did
the background check,

and we ended up
sleeping together.

But that's it.

Why didn't you just tell
me that from the get-go?

Why do you think I didn't tell you?
I work counterintelligence.

I'm supposed to be following
people like Kim.

You're telling me that
you knew she was a spy?

I had a pretty good idea.

How about an idea
about killing witnesses

who were going to testify
against a fugitive

on the U.S. Marshal's
Ten Most Wanted list?

Think I had something
to do with that?

What do you want me to think?!

After I got back
from Afghanistan,

things with Jenny and me
went south quick.

I ended up living
in a small apartment

with some judge telling me
when I could see my son.

After I interviewed Michelle,
she called me,

and we met up a couple of times.

She showed me some
attention, you know?

I knew better,
but I went for it.

But that was all it was.

So when-when was the last time
that you actually saw her?

Not the night she was killed.

Look, a-any of this
becomes an issue,

I will come clean --
you have my word.

(sighs)

You'd be baked inside a Humvee
if it wasn't for me.

You really think
I'd screw you now?

(sighs)

CHARLIE: You know, the number
of espionage cases

that we've prosecuted in the
past decade has increased... 300%.

Spies, huh? Is that
what you're working on?

Yep.

Hey, did you know that nobody
ever heard of James Bond

until President Kennedy
confessed

that he had read the Ian Fleming
novels before going to bed?

Did you know that?

What, you don't believe it?

Well, this is more than fiction.

Hey... you ever
have a problem with...

someone that you
respected at work?

Why, you having
troubles at work?

Larry.

- Larry?
- He published his latest paper.

He didn't ask me to collaborate.

Well, I mean,
with his experience,

what has he got to do,
check with you?

- Well, okay, that's not the point.
- Well, what is the point?

That his paper is good.

It could be great.

With your help, huh?

Well...

You know, there was
a time at work,

I was at the City
Planning Office.

My, uh, my boss had
a design, and, um,

I don't know,
I thought I saw something.

I mean, the plan
was fine as it was,

but I thought that, um,

I had seen something...
that I could make better.

What'd you do?

Nothing.

Because I had to decide
which was more important,

my relationship with my boss
or with our client.

Why don't you ask yourself this:

Are you really ready to tell
Larry that his work is good

but just not good enough?

COLBY:
Hey, David.

Any luck finding
more cameras in Kim's building?

No, these were the only
ones, here in the lobby.

Couldn't really tell which apartment
the guests were going up to,

and so far Kim's
always been alone.

CHARLIE:
You know, um...

(clears throat):
that might not be true.

What's up, Charlie?
What are you doing here?

Well, I'm just...
working on something for Larry.

Look, you said that the footage
from these cameras is archived, right?

Yeah, that's right.

Okay, well, then, look, if the
apartment is a meeting place,

then chances are your mole
has been there more than once.

Yeah, but, I mean, there are months
of footage and hundreds of guests.

Okay, but we know when
Kim was there, right?

Yeah, but so?

So I can run
a series of Eigenfaces.

COLBY:
Eigenfaces?

Advanced facial-recognition
techniques.

I've been working on a program
that matches human asymmetry.

So I can create an algorithm

that matches all visitors
to the apartment

at the times that we know
that Kim was there.

Asymmetry points?

Come on, Charlie,
help us out here, man.

(sighs): No human face
is perfectly symmetrical.

Let's say that each little
square of a Rubik's Cube

represents a symmetry point --
nose, ear or eye.

When the right combination
is found,

an individual symmetry point
or body part is matched.

Hey, I just heard from the LAPD.

There's a chop shop in
Van Nuys that has an SUV

that matches the
one that hit our girl.

- What's up?
- Help you with something?

Yeah. You Tyler?

- Yeah.
- I want to get some rims.

What size?

- 22's.
- How many you need?

- COLBY: Four of 'em would be great.
- Four rims.

Means we've got four guys
to deal with.

Nice and chromed,
if you can swing it.

Chrome.
Somebody's got a gun.

All right, let's go.

Call it a thousand even.

FBI! You! Down!

Hey! You with the gun!
Put it down!

Hey! Put the gun on the floor!

Hey! Hey! Don't!

He dies, you die!

Oh, no, no!
Here's how it goes!

I get out of here,
or you both die!

David, shoot this dude.

- Will you just shoot him?!
- Shut up!

- Drop him now!
- Shut up! Shut up!

Easy! Easy. Think.

Think about it --
there's no way out of here.

You got no options.
Put it down.

- I mean it.
- David,

shoot...

- (grunts)
- (yells)

(Tyler groaning, coughing)

(cries in pain)

You okay?

Yeah. Already
told you, I'm fine.

That was a close call
earlier, man.

Comes with the territory, right?

Just saying, man,
that's not like you

to not bring
your "A" game, brother.

A guy gets a jump on me,
and suddenly I'm losing it?

I'm just saying, man.

Last couple of days
you been kind of quiet.

I'm your partner, man --

if there's something on your
mind, just let me know, okay?

Look, David, I appreciate what
you did in there, all right?

But I am fine.

See you tomorrow.

Okay.

Hey, I got it.

Got what?

I-I got an idea on your mole.

That asymmetry model
really paid off.

Check this out.

This is your
most likely suspect.

The past three months,

Kim was at her
apartment 24 times --

eight of those times this
guy shows up within an hour.

You sure about that?

Yeah, I mean, I'm very sure.

Once I established this image,

I cross-referenced it
with the photo I.D. database

at the Department of Justice.

Whoa...
that's Dwayne Carter.

Isn't that, like,

Colby's Army buddy
in Counter Intelligence?

It's not like; it is.

Hey.

Where is he?

He's on his way in.

What are you gonna do?

I don't know yet.

What, you got something
you want to say?

Don, if Colby
withheld something,

I'm sure he had a
good reason for it.

Where are we on the warrant
for Carter's place?

The attorney general
approved that this morning.

All right, well, as soon as they let
us know he's out, we're going in.

Sure you want to wait?

We have enough to bring
him in right now.

That's Homeland's call --

they want to find out
more about the setup,

see if there's any connection
to the consulate.

Well, so far, the cash withdrawals
from Kim's bank account

correspond to a bunch
of deposits that Carter made,

but we haven't had any luck
tracing Kim's source.

Just keep digging.

Hey, you wanted to see me?

Uh, yeah, you got that right.

All right, straight up, I want to know
if you knew it was Carter on that tape.

(exhales) I had a feeling, yeah.

You had a feeling,
and you don't bring it to me?

Don, the guy's a friend of mine.
He made a mistake.

It had nothing to
do with the case.

Your friend is bought and paid
for by the Chinese government.

(sighs)

I had no idea.

Any money exchange hands
between you two?

You lied to me -- I'm not exactly
clear on the reason now.

I would never tank
an investigation, Don.

- You know that.
- Well, you crossed the line here.

What, and you haven't?

Excuse me?

When Megan was kidnapped --
you know what I'm talking about.

Yeah. To save a life?

Yeah, I was trying to save a buddy's
career from going down the drain.

Look, Dwayne admitted to me
that he was sleeping with Kim,

but he swore to me that it
had nothing to do with our case.

He swore to you.

Look, you're off the case.

(groans softly)

Do you have him?
Megan?

Megan.

Biceps look pretty good.

He should be in there a while.

Now that you're done staring,

we might be able
to get the job done.

(mock chuckling)

Dining room.

Bathroom.

Clear.

I got a laptop in here.

(chuckles) Hey...

they look like brothers there,
don't they?

Yeah.

I'm in.

Damn it, he's getting out
already.

No, no, I need more time.

How about 45 seconds?

Do I have 46?

44. Come on.

David.

I'm coming.

Come on.

- (knocking)
- Yeah, I'm coming.

- Hey, Larry.
- Alan.

Hey, is-is Charles here?

- Uh, no.
- Good.

That's good.

That's very good.

Can I get you something?

Hey, look at this.

Why, to graduate Princeton
at 16!

I was good, but...

it took me till the
more normal age of 19.

Yeah, well, in that first year,

we heard an awful lot
about Professor Fleinhardt.

Yeah.

You know, he spent half the time

trying to prove the
T.A.'s thesis was wrong.

Well, Charlie was never afraid
to give his opinion.

Yeah, well, of course,
Charles was right.

Is there something
bothering you, Larry?

Charles is having trouble
understanding

why I didn't ask for his help

on this recent paper
that I published.

Oh?

Yeah. I mean, it's not
that I don't value his input.

I mean, you know that I do.

- But?
- Alan, Charles's work

at the FBI
increasingly consumes him.

Yeah, we know that, but...

In my field,

dependence on any one person,

that can spell the end
of a career.

And I'm just not ready to go.

Not yet.

You know, there's also
something called pride,

and I've never found that a
great justification for anything.

That was SOG.

Bank manager inadvertently
tipped Carter off

that subpoenas are being
served on his accounts.

Well, is that your way
of saying he's gone?

Yeah, he knows we're on to him.

All right,
if Carter's on the run,

then he has access to all kinds
of fake IDs, passports.

Yeah, but we have his money.

Just let me ask you this:
you think he's the type of guy

who's gonna hang around
for like one last score?

I'd buy that.

He probably has the name
of every FBI informant

working against the Chinese.

We have the Consulate covered,

so there's no way
he's gonna make contact there.

I mean, it could be
pre-arranged, right?

Look, he's meeting her
on a regular basis.

Yeah, but that was at
the apartment.

Yeah, but at some point,
his handlers got to want to meet him,

they got to want
to check him out.

And there's no way she's gonna
bring them all to that apartment.

You know, Carter's PDA

had a bunch of meetings
on company time

that the Bureau
couldn't explain.

Yeah, you got the times?

They're all like
11:00 to 1:00.

Well, you have, uh,
the locations of the meets here?

They're spread
throughout the city.

You know what, do me a favor,
e-mail them to Charlie,

maybe he can come
up with something.

MEGAN: We're worried
that Carter's going to try

and sell whatever information he's
got before he leaves the country.

And these appointments
from Carter's PDA

are meetings between
him and the Chinese?

We think so.

Hmm...

Well, a lot of these addresses

are within a couple miles
of the FBI.

Now I've learned from the NSA

that operatives will often
schedule meeting places,

like, months in advance --
they're given a list.

And no two meeting places
are ever the same.

Okay, so we can then
logically assume

that the meeting place is
somewhere inside this circle?

Right.

It's a classic combinatorial
optimization problem.

And no one is better at
combinatorics than you.

Who else could be?

It's simply a question
of branching and bounding.

Branching and bounding?

So you're trying to predict
how a tree is going to branch.

And you know where
six of the branches'

meeting places already are.

Now where will that
seventh branch --

Carter's next
meeting place -- be?

Certain factors can help us
eliminate potential branches.

Like, we know that Carter has to
make a clean and fast getaway.

See, these meetings
are taking places in areas

that are zoned for businesses with
open courtyards, with promenades,

with multiple entrances
and exits.

One was Pershing Square...

And one was the Staples Center.

They're both close to the
freeway, easy getaways.

Right, and so,
by running an algorithm

that analyzes the features
of the existing meeting places

to find key variables,

then by applying a branching
and bounding algorithm,

we can hopefully identify

where Carter's next meeting
place will be.

Okay. Thank you.

DAVID:
Sinclair for Eppes.

Go for Eppes.

SOG's got nothing on the other
locations Charlie's listed.

All right, just give it
time, you know?

I thought Carter took all of his
meetings during the daytime.

That's why it's called
probability.

Wait, hold on.

Yeah, I got eyes on him.

DAVID: Whoa, that's Chen,
the guy from the Consulate.

I don't know,
he looks pretty calm.

I don't think he knows
we're on him.

Don, Carter just passed him something.

DON: All right, Position One, follow him.
Don't bumper lock.

Bravo Team take Chen
outside the park.

We got Carter.

(over radio):
Roger that, we got Chen.

Adam-23, go.

Bravo team, copy.

All right, he's turning right
onto Broadway.

Stay back, everybody.
Wait for me, wait for me.

- Copy that, David?
- Copy that.

MAN: Got units stationed
Fourth and Glower.

All right, wait.

He's going eastbound into
the Second Street tunnel.

All right, let's box him in.

- (siren blares)
- Sinclair to Adam 23.

I want you to lock up the east
end of the Second Street tunnel.

Shut it down right now.

(sirens blare)

Get your hands
out of the windows!

Get your hands
out of the windows now!

Driver, keep your hands
out of the window,

open the door
and step toward my voice.

Nice and easy.

Just step toward my voice.

Dwayne, you don't want us
pulling you out of that car.

I'm doing it!

Don't shoot!

Unit 17, shut down east side
of Second Street tunnel.

Come on. David.

Come on, hands behind your back.

Come on.

You've got to be kidding me.

Colby was right,
this guy is good.

Here, catch.

Unbelievable.

Chen isn't talking to anyone,

and the State Department's
certainly not going to lean on him.

They've got bigger stakes
with China.

We've got surveillance on the
airports, public and private.

Border Patrol has a copy
of Carter's profile.

Guy works in intelligence
ten years,

he's not taking
public transportation.

Don, if Carter has an exit plan,

Colby is our best chance
for figuring it out.

Yeah, well, Colby's
not on the case.

I mean, I can't trust him.

Whatever happened between him
and Carter blurred his judgment.

Why don't you let David
try and call him?

I already tried.
Got his voicemail.

Guy's got something to say
to me, he knows where I am.

Guess you got to keep the boat
in the divorce settlement.

Do me a favor and untie
that bow line.

For a guy who loves the ocean,

I never could understand why you
chose to go to the desert.

If I hadn't, you'd be dead.

They took my badge, my gun.

Then there's nothing
keeping you here, right?

Look, I got something to sell
that'd be enough for the both of us.

Yeah, and how many people
are gonna die this time?

You killed two
innocent witnesses.

And Michelle Kim?

When I met her, I must've looked
like a deer caught in the headlights.

I mean, this girl,
she was all over me.

At first, it was just
drinks and sex.

Yeah, and then what?

I was only giving her
useless information.

And every dime of it
went to my kid.

No, the information you sold
her killed two federal witnesses.

A murderer went
free because of it.

She blackmailed me.

She told me if I didn't steal

high-level information,
she would expose me.

So, what, you killed her
to save your ass?

I saved your ass once.

You remember?

What help am I to my son
if I'm in prison?

There was nothing I could do.

I didn't have any other choice.

You got a choice now.

You can come in with me.

It's not gonna make
anything right,

but it might just give
your kid one chance

at least to forgive his father.

What if I don't?

Huh?

You were one of the bravest
soldiers I ever knew, Dwayne.

(yells)

No!

Granger.

Granger...

Come on, give me the tape.

Give me the tape.

You gonna kill me?

Go ahead, man.
Go ahead.

(distant sirens approaching)

Put it down!

Carter, drop the gun!

Colby, get out of the way!

I can't believe
you did this to me!

Drop that gun!

- Put it down!
- Drop it!

No.

No, Dwayne...

no, you did it to yourself.

Dwayne Carter!

Drop that gun!
Put it down!

Hands up! Now!

Hands up!

Drop the gun.

You know, I've
never been in combat.

But I've been in my
share of fire fights

and you know what scares
the hell out of me?

It's not dying.

It's letting my guys down.

You know?

Losing trust.

You do it again,
you're going to jail.

Still trying to untie yourself.

There's over 70
precise moves with this.

Well, they don't call it the world's
toughest brain teaser for nothing.

You know, I used to be able to
do these in under two minutes.

Now, it's over six.

Oh, that's still pretty good.

Yeah.

It's not my best.

Neither was hiring Stromsborg
as my collaborator.

Larry, we've discussed this,
Stromsborg's good.

Yeah, but he's not the best.

What I forgot to keep in mind
was the paper meant nothing.

You see,

it was all about the work.

Or should've been.

Speaking of work,

I could still use your help...

if it's not too late.

Larry...

I have a confession to make.

Yeah?

I already read the paper.

Oh.

And?

You want me to be honest
with you?

No, I don't.

I want to remain
a blithering idiot.

Yes, of course,
I want your honesty.

Larry...

I never want to lose you
as a friend.

And you never shall.

Your paper...

it's a work of genius.

Okay, now there.

Was that so hard?

- But...
- But...

it would have benefited

from the work of two geniuses.

Yeah.

Simon and Garfunkel, perhaps?

Okay. Fine, yes.

As long as I'm Simon.

Well, Charles,
ever the pragmatist.
