Numb3rs (2005–2010): Season 4, Episode 1 - Trust Metric - full transcript

Peter MacNicol returns as a regular cast member. Colby is being interrogated by a man named Agent Kirkland, who passes him a handcuff key and gives him escape instructions. Don and his team get information about and from Colby and must figure out if that information is reliable then realizes that everything about Colby being a double agent may not be what it seems.

Previously on Numbers:
Dwayne Carter.

We did a tour
together in Afghanistan.

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

The man who saves your
life... You put him in jail.

Things I could tell you about
squeaky-clean Colby Granger.

If you find the
Janus List, trust it!

(explosion)

Ashby was building a Janus List.

A master list of double
agents and traitors.

ASHBY'S VOICE:
Welcome to the Janus List.

The following people
have been co-opted.



United States FBI agent
Colby Granger, by the Chinese.

DON (on video): I mean, do you
understand what you're telling me?

COLBY: Nothing you don't know.

Nothing everybody's not
going to know tomorrow.

David... How long have
you been lying to us, huh?!

DON: Just relax. COLBY:
From the beginning, David.

That's what a spy does.

You ain't no damn spy!

You're a traitor!

All that crap about
serving your country!

Get out of here!

You ain't no damn spy!

You're a traitor!

All that crap about
serving your country!



Get out of here!

DON: Spying on your own country?

I mean, do you understand
what you're telling me?

♪ ♪

(indistinct
conversations, laughter)

(panicked shouting)

This man, do you know this man?

♪ ♪

Do you know him?

This man, you
know this man here?

Yo, turn around!

♪ ♪

You know him?

I will put cases on
every one of you!

Every one of you!

How long have you been
lying to us, huh? Just relax.

You ain't no damn spy.

You're a traitor.

All that crap about
serving your country!

Get out of here.

COLBY: Dwayne Carter approached
me while I was in the Academy

and asked if he could make
a copy of a training manual.

It didn't seem like a big deal.

You know, he'd ask for a file
or a pass code to a database.

Before I knew it, I was
spying for the Chinese.

It didn't seem like a big deal.

You know, he'd ask for a file
or a pass code to a database.

Before I knew it, I was
spying for the Chinese.

CHARLIE: So consider
the game of chicken

in which there are
three Nash equilibria.

Each driver can choose to
drive straight at the other...

Consistent with a
rational strategy...

And rationally crash.

So game theorists recognized

this conundrum during the
1950s as we contemplated

nuclear annihilation.

Mathematical theory confirmed

what we instinctively
understood... that the sane man

often operates
at a disadvantage.

So what am I illustrating?

I'm illustrating the
ability of math to do more

than define the
parameters of our lives.

It can illuminate
the human condition.

And some day,
perhaps, it will even

define what lives
deepest in our hearts.

Okay?

Tomorrow, however, we are
going to return to parameters.

Specifically partition
congruences.

All right, you guys are done.

Enjoy the rest of your day.

(clears throat)

Oh, hey. There you are. Hi.

Your analysis of game
theory seems a little bleak.

Oh.

(laughing): Yeah.

And I noticed you
haven't been doing

any consulting work for the FBI.

Well, Don hasn't
asked me, you know.

Honestly, it's been kind of
nice getting back to teaching.

Breathing.

Kissing you.

Before I knew it, I was
spying for the Chinese.

DON: Yeah? How did it feel?

Spying on your own country?

I didn't do it
because I believed

in Communism or China.

I did it because I could.

Because after Afghanistan,

I just didn't really believe
in much of anything.

So, are you finding
your answers here?

At least the monks and I are
asking the same questions.

Hmm.

Hey... Well, I'm
sure you know this.

The Dobsonian telescope
owes its very existence

to the hours that
John Dobson spent

at the Vedanta
Society monastery.

I did not know that.

Oh, I just think I needed

some kind of surcease
from the madness

of daily obligations.

You...

to what do you owe your respite?

What makes you think
I'm taking a respite?

Well, given the many
hours you've spent here,

their distribution over
the past many weeks...

I mean, it's highly doubtful

that you could be maintaining
your official duties as well.

I had some leave time coming
that I think I really needed.

You know, with everything
that happened with Colby,

and my work for
the DOJ before that...

Still not at liberty
to discuss it?

I'm not sure that I'm ready.

You know, I...

I feel like I've been
sleepwalking since I got back.

I'm... I'm physically present,
but I'm somewhere else

at the same time.

You know, I had a
very similar experience

on my first space walk.

Just this sense of, oh...

For want of a
more elegant term...

Quantum disconnectedness.

And did it go away?

Unfortunately, it did.

Hmm.

DON: Who else was involved?

Carter was my cutout.

He never let me
near his handlers.

ALAN: Donny?

Come on. It's been five weeks.

There's just something
about his confession.

It just... doesn't feel right.

I mean, do you understand
what you're telling me?

DON: It just doesn't seem right.

ALAN: Like what?

I don't know.

Like, I didn't see it
coming, for one thing.

Well, no one did.

Come on.

You got to allow yourself
a few mistakes in life.

Yeah, well, people die that way.

How's it been?

Last chance to turn back.

I've spent two years lying to
everybody about everything.

Stop now, it's all for nothing.

Expect something to
happen during the transfer.

Take the guard's cell phone.

Number six on the speed dial.

Who else knows?

Almost no one.

So I'm alone.

You got me.

(sighs)

(sighs)

MAN (over radio):
Delta Three Niner,

confirm for transpo
to secure facility two.

(speaking Spanish)

(man singing in
Spanish on radio)

Any chance you got some
Johnny Cash up there?

Seriously, I may be a traitor,
but at least I'm an American.

Any of you guys
even got green cards?

Dwayne, do you ever shut up?

Solitary for three weeks...

Conversation's
been a little thin.

♪ ♪

Excuse me for being social.

(tires squealing)

(truck horn blares)

(groans)

Don't move, or I'll
blow your brains out!

Dwayne, grab his gun.

(indistinct yelling)

Ride's here.

(sirens wailing,
tires squealing)

This ain't going
our way, Granger.

We got to go.

GRANGER: Hey, get down!

Don't move.

WOMAN (on TV): We could see that
there was a fire or explosion of some sort.

We're getting no confirmation...

Oh. Didn't hear
you get up. Oh, hey.

Well, you know, since
Millie's been on me

to publish lately, I
thought I'd dust off some

of my insights into
Groebner basis calculations.

"A Mathematical Analysis
of Friendship Dynamics."

Yeah, I figured I could navigate

through the 11th grade
using the minimax theorem

and n-person games.

Did it work?

Actually, my insights into
the network externalities

of school elections were
absolutely bulletproof.

Payoff strategies for doing
other people's homework were not

quite as well reasoned.
ALAN: I'm telling you.

It's absolutely
new. I just bought it.

I know, but this is, like,
your third one this year.

With the shoes, which I
have to try on right now.

Charlie, last chance.

Oh, I-I... I love the
game of golf, but no.

Thank you. We have
other plans, all right?

All right, all right.

Can I see this? I
still remember this.

You remember it? Yeah,
yeah, the Friendship Math, right?

Wow. Yeah. That's
right. Yeah, yeah.

I tried to read this. Really?

Yeah. I thought I could... Why?

Uh, you know, I thought I
could, uh, pick up girls with it.

Of course. What, it was,
like, 11th grade, right?

Wow. Yeah. (phone rings)

11th grade.

All right, Dad, let's
get out of here. Eppes.

Oh, no. They're
going to be too small.

DON: What?

When?

Yeah, yeah, all right. Uh...

Yeah.

I'm on my way. I got to go.

ALAN: Why? What's up?

Dwayne Carter and
Colby just escaped.

(pry bar clanging)

There's gotta be
something in here.

Where's my keys? Where
the hell are my keys?!

You left them on the
hook in the kitchen.

Charlie, I think
you better help him.

Come on, you did this
before. What was it?

Uh, chase curves, right?

Pursuit curves,
and they're not really

applicable here, Dad.

Although, you know, I
have always suspected

that the Set Covering
Deployment Problem

could be an invaluable aid
in positioning police units...

DON: No, no,
these aren't my keys!

They're on the coffee table.

MAN (on TV): there was a
fire or explosion of some sort.

We're getting no
confirmation from the LAPD

or the Department of Defense...

CHARLIE: It's
potentially revolutionary.

Now picture,

uh, picture a
coastline at night.

To keep ships from
crashing on the rocks,

we build lighthouses, right?

But lighthouses are
a limited resource

because they cost time,
they cost money, materials.

But using Set
Covering Deployment,

we can determine
the best placement

for our limited
number of lighthouses

to illuminate the ocean.

Put your ankle up here.

Where did you get the key?

Swallowed it right
before they busted me.

Figured it was just
a matter of time.

Standard-issue cuffs
use the same one.

Give me this thing.

I have to make a call. Use the
phone right in the office there.

Right in there.

No, it's me.

Yeah, we need a ride.

Now!

Hold on.

5th and Alvarado?

We got a ride, but we got to go

to 5th and Alvarado. All right.

Hey, man, put on
something to cover that up.

Oh, yeah. Good idea.

(siren wailing) Oh, man, I
must've tripped the alarm.

What? The cops! The alarm!

Say, Mike, what do you got?

Thanks.

What's up, Megan?

Thanks for coming back early.

All right, so what do we got?

Carter and Granger
were being moved

to a new holding facility.

The transport was
ambushed en route.

Driver hit the panic button.

The response time was faster
than they probably expected.

Which would explain why
there's two dead, a third in critical,

and the fourth guy was
ID'd as Jimmy Hong Tran.

What's that, like, Vietnamese?

Yeah, he's a local
mope. He's not talking.

Strictly hired muscle.

Granger and Carter
used a diversion,

overpowered the guards.

They slipped away
during the firefight.

Now, eyewitnesses saw
them taking off down Hill Street.

They were shackled
together at the ankles.

But the driver said that
Colby's hands were free,

so they must have
gotten a key somehow.

Yeah, it's right here.

That explains
how they got loose.

And if they lost it,

why they're still
in leg shackles.

Yeah, so they're gonna be
trying to cut those off, right?

Charles, the monks do
not appreciate FBI agents

knocking at their doors,

especially during
morning contemplation.

Yeah, I didn't have
any way to call you.

Yes, by design.

You know, much as I respect,
I've even embraced your work...

Colby escaped from jail.

All right.

So you're programming a matrix
for Set Covering Deployment.

It doesn't seem to be much
use for a cosmologist here.

Plenty of use for
a friend, though.

Look, intellectually, I know
that this case is no different

than any other case
I've worked on...

A problem needs to be solved.

And, as in every case,

there is a human component.

In this instance, a
personal component.

I can't reconcile

what I know about the
man with his actions.

Try as I might to put
that out of my head.

Oh, no, no, no, no, no, Charles.

You ignore any reality, no
matter how uncomfortable,

only at your own risk.

But on the other
hand, you incorporate it,

and I don't know,
who knows what insight

might rise up here
from the depths.

I'm not sorry I dragged
you out of bed, Larry.

♪ ♪

They lost the key,
they cut the link.

It looks like one of them
is still wearing a belt.

They made a call. Tried to.

Well, I can get a dump
on the phone line. Yeah.

DAVID: All right. Hey.

LAPD lost them in a back alley,

but thinks they might've
ducked into the farmer's market.

Why are we doing this?

We're acting like this is
any other case, and it isn't.

What do we do? Go home,
leave it for somebody else?

No, I think we got to address

what we're feeling 'cause
it's affecting the work.

I'm feeling like I'd really like
to put them back in prison.

Sure you're up for this?

Hey, that's not fair.

That's not what I said.

What do you want me to say?

How do I feel?

I feel like it's my fault.

That Colby's my responsibility.

We move the foot patrols

into the unknown
occupancy grids.

Won't that compromise

the coverage in
the central zone?

Okay, how about a terrain
guarding algorithm? (phone ringing)

It's always terrain guarding
algorithms with you.

Hey. Charlie Eppes.

Charlie, it's Colby.

COLBY: I need to talk to Don.

CHARLIE (on phone):
Then why call me?

Because the FBI doesn't
have enough time to trace me

through your phone, Charlie.

Look, think like
a mathematician.

Is there any reason

not to put me through to Don?

Uh, no.

It's Colby.

I got to call you back.

What, you call my
brother? Is this a threat?

Don, my handler is
Agent Michael Kirkland,

counterintelligence out of DC.

Your handler?

Look, when Dwayne first
came to me back at Quantico,

I reported it.

Kirkland has been
using me to feed

cherry-picked information
through Dwayne to the Chinese

because he's sure
that Carter's working

for someone high up at the DOJ.

Who's that?

That's the thing, Don, we
haven't flushed him out yet.

When Carter got busted,
Kirkland figured if I got thrown

in jail with him and escaped
with him, that was our only shot

that he might lead me up.

But the problem is,

I can't get ahold of
Kirkland right now.

I don't know if something's
happened to him

or if I'm being set up.

Who else can verify this?

The ranking guard
on the transport.

Other than that,
Don, I-I don't know.

Kirkland kept this whole
op extremely contained.

Colby, you're giving me a
story here I can't even check out.

I'm giving you Kirkland, Don.

Okay, you don't trust me.

I get that, all right?

But you have to
understand that I trust you.

The fact is, you are

the only person that
I can trust right now.

So DC says there is

a Michael Kirkland
in counterintelligence,

and he's been in North
Hollywood for the past six weeks.

Any number of ways
Granger could've known that.

It could be a name he sold to the
Chinese. So you go talk to him, all right?

But, uh, let's just keep
this among ourselves, okay?

We're not going

to report contact with
an escaped prisoner?

No, I just want to find
out what Colby gains

by telling us this
story, you know?

MEGAN: Because you think

he could be telling the truth?

Any of you familiar
with trust metrics?

Uh, sure, in psychology,
it's a measure

of how much a member of a group
is trusted by the other members.

We can't trust
anything Colby says.

Well, it's not an
either-or proposition

if we employ a fuzzy system.

Yes, I am done with that.

Now, how would we
describe this ice cube?

Wet, hard, cold.

But none of those
words mean anything

unless we have a
basis for comparison.

Using fuzzy logic, we
create a range of those states,

and assign the ice
cube values accordingly.

Similarly, a person's honesty

is not absolute; we all lie

to varying degrees
for varying reasons.

DON: So what, you're going
to tell us what percentage

to believe him?

More like a
probabilistic statement.

Let me do the work.

If you guys don't
want to use it,

then at least I tried.

Charlie, don't you really
have your hands full

trying to figure out their
possible escape routes?

Actually, my Set
Covering Deployment

yielded a very
interesting byproduct.

AMITA: So we created a
dynamic, adaptive system

adjusting for crowds,

911 calls and
suspicious activities.

Yeah, of course, it must
seem all fairly abstract to you.

No, no, no, I get it; the
thicker lines are higher

probabilities, right?

We start where they escaped,
take them to the garage.

Why do the subway
stations have lower values?

Coverage... there are police

on the station
stairs and platforms.

DON: Yeah, but
not all the trains.

If they disappeared here...

And they haven't shown
up here, right? Yeah!

Well, well, Don has gotten
much better at the math.

He puts on a good game face,
but he seems like he's hurting.

Well, it's hard enough
Colby betrayed him,

and now, even more confusion

about who he is
and what he's doing.

You know something, we
might do well to consider

a strange neutral B meson here.

Okay.

If something as simple as...

as a heavy bottom
antiquark bound

with a strange quark can

reverse its identity three
million times a second,

how do we expect something
as complex as the human mind

to simply remain unchanged?

Colby!

Don't move!

Colby!

Don't move!

Colby! (train horn blowing)

Colby, Carter, freeze!

Carter!

Ah, damn it!

I let Colby go.

Oh, come on, man,
you didn't let him...

But we do have to assume that

he's moved beyond the boundaries
of my Set Deployment by now.

I let him get away. I had
him. I was looking right at him.

All right.

Were you basing your
decision on his statement,

the circumstantial context,

or a disposition towards

giving him the
benefit of the doubt?

What, are you actually
putting it in an equation?

Well, of course, man.

It factors into my trust metric.

I mean, I just, I don't
know why I believed him.

Unless it's so simple
as I don't want to admit

I was wrong in the first place.

Don,

you have a big ego. Thanks.

No, you have a ginormous ego.

Thanks. But you're
not stupid, you know?

You made the best
decision you could

with all the available
information you had.

And if past performance
is any indicator, man...

you are probabilistically right.

Probabilistically, huh?

I know math is full
of absolutes, and...

unfortunately,
the rest of life isn't.

This guy doesn't say much, huh?

Never heard him
talk, come to think of it.

Remember when I dragged your ass

out of that Humvee?
Yeah, you remember why?

Sometimes I think the burns are

payment enough for the
things that we've done.

Other times, I know they're not.

Holding that key, sitting
in jail for five weeks,

you trusted me to make a move,

and I knew I could
trust you to wait.

Well, we're in this together,
right? Damn straight.

The rest of them can go to hell,

as long as we keep dragging
each other out of the wrecks.

What were you thinking

trying to shoot it
out with the cops?

I was thinking, I'm gonna
die before I go back to jail.

DAVID: You know this
is a smoke screen, right?

Granger sends us off chasing
ghosts while he gets clear.

You know, the best
way to find out is

we'll just ask
Kirkland ourselves.

Do you smell that?

Only one thing smells like that.

Damn.

(grunts)

Clear.

Mmm.

Special Agent Michael Kirkland.

It's Agent Sinclair.

Yeah. Oh.

Do you have an Agent
Michael Kirkland?

Yeah, he's dead.

Whoever tortured
Kirkland didn't know he had

aortic valve stenosis.

Induced a major heart attack.

And DC is pushing us off.

Their official
statement is that, uh,

because Kirkland was
in counterintelligence,

his operations may be beyond
our "need to know." Yeah?

What about unofficially?

I got the impression

no one has any idea what
he was doing in Los Angeles.

Obvious theory is, he was a spy.

Maybe Carter's mystery contact.

He outlives his usefulness
with the Chinese,

and they kill him.

Well, what do you think?

I don't know.

DC's already asking us

how we found the body...

Don, we have to come clean.

Look, if Colby's
telling the truth,

we got a leak at the DOJ.

Come on in.

How you doing?

Take a seat.

Any problems?

Nothing we couldn't handle.

Do you know who I am?

Should I?

Well, that's a question I need
answered, Agent Granger.

Oh, it's not “agent” anymore.

Mike Kirkland says differently.

Am I missing something?

You've been missing
it for two years.

He's a triple agent, Dwayne.

He's been feeding us lousy intel

and spying on the FBI
for the last two years.

(cocking gun)

May I have the,
uh, phone, please.

How long were you
planning on playing this?

All the way through to China?

If I had to.

So, you were
responsible for transporting

Carter and Granger?

Yes, sir.

The orders came in late.

I was ranking
officer on the block.

Sir, am I in trouble?

You know an agent
named Mike Kirkland?

No, sir.

All right, let's suppose

your orders were, in fact,
to help these guys escape.

Agent Eppes, are you
accusing me of treason?

That's what helping traitors

escape from custody
would be... treason.

Agent Kirkland was found
dead this morning, okay.

So, if there was some
kind of classified operation

going on, there's
people's lives in jeopardy.

You understand what I'm saying?

Yes, sir.

DON: Kirkland
picked the right man.

The guy can
definitely keep a secret.

Or he has no idea
what we're talking about.

All right, either way

it would only
confirm Colby's story.

It's not going to
help us find him.

All right,

maybe we're just
chasing this thing wrong.

The last time we went
after Carter, what did he do?

Made a run for China.

Then he arranged a
murder from prison,

he pretended to
cooperate with us...

Yeah, but that was only

to convince the CIA to
trade him back to China.

Right, so how's he
plan to get there?

You're suggesting

we develop a projective
analysis assuming

that Colby and Carter
intend to get to China.

Not Colby... just Carter.

Everyone agrees

on who he is, you know,
what his motivations are.

Well, that makes sense, Charlie.

Isn't there a
mathematical term for, uh,

uh, removing the clutter?

Yeah, we call it
“removing the clutter.” Oh.

(chuckles)

I mean, I suppose we could
develop some expressions...

I have to go.

Well, that's how
it is, you know.

He gets an idea.

Yeah.

So, how you doing, David?

Uh, you know, just

trying to treat it like
another case, you know.

I don't see how you can.

I mean, it's you
and Colby and...

Yeah, that's the
thing about friends...

sometimes they turn on you.

Yeah, that's the
big test, isn't it?

How do you deal with a really
close friend who lets you down?

Mr. Eppes,

he did not just forget to
pick me up from the airport.

He sold out his country.

I don't want to get all
1960s on you, but, um,

I've heard that accusation
tossed around a lot

in my lifetime.

And the truth is, uh...

it's never that simple.

I mean, you might owe
it to yourself and Colby...

to try to understand
why he did what he did

before you actually
close the book on him.

Excuse the camera.

I can't remember
things like I used to.

I should have realized you
were a plant from the start...

we have that in common.

I was born in Beijing...

Absorbed into an
extensive training program

just after I could talk.

They sent me to
the United States

where I was educated
and assimilated.

I was even pre-med before I...

followed my path into
government service.

Unfortunately,

Kirkland died before
he could answer

the important questions like,

does the FBI know my name yet?

And, um...

if I go to Washington,
will I be arrested?

Why don't you just ask Dwayne.

He's been working
with us this whole time.

Why don't we start
with something simple...

Something I already
know... Like your op name.

Arabian Knights.

Stalking Horse.

Lesson number one...

You can't lie,
and I don't bluff.

I may need to find
a new monastery.

(bell tolling)

So, I was on my way to the FBI
to help answer some questions,

and I had to stop and
take a deep breath

before I went
the rest of the way

because I'm not sure
about the optimality

of giving Don the
solutions he's asked for.

Why, because you're not
sure he'll use them wisely?

Well, because I'm
not sure they're right.

I mean, they're right,
but... how can I be sure

that they'll produce
the right outcome?

Yeah, well, you've certainly

wrestled with this
question before.

Yeah, the stakes have
seldom been so personal.

Well, you know, one could posit

that any outcome
the solution produces

is the one that was meant to be.

Science transcends
functions, facts...

It's all a path to
understanding higher truths.

Just yesterday I made
that very same point

to my Intro Game Theory Class.

Every professor
should spend time

in the back of his
own classroom.

Ah, you're right. Thank you.

Sorry to interrupt
your meditation.

Silent contemplation has
certainly taught me one thing.

What's that?

You can contemplate silence,
but you can never find it.

What I administered

was a nonlethal
dose of tubocurarine.

It paralyzes the muscles

and depresses the
respiratory capabilities,

creating what I've
heard described

as the sensation
of slowly drowning.

You and I are in
the same position...

Both fighting for freedom,

we're both fighting
for our lives.

Think of what you'd
do in my position,

multiply that by five,

and you'll understand what
I'm willing to put you through.

We assume that
Dwayne Carter intends

to get to China from Los Angeles

by a direct and safe path.

Now, he is aware

of all the resources
at your disposal...

Police dragnets and
surveillance on family and friends.

I mean, you don't need
Karmarkar's algorithm

to see where this is going.

Ernst Straus posited
a roomful of mirrors

and a man lighting a match.

Like lighthouses,

that man wants to
illuminate everything.

Now, as the reflection
of the light bounced

from wall to wall,

Straus wondered if there
was a room so complex

that a match lit
in the right place

couldn't reach every corner.

Well, it was 40 years

before George Tokarsky

devised an answer...
A 26-sided room.

In the spirit of that
problem and solution,

I looked for Carter's
dark corner...

The nearest,
safest Chinese soil.

We already have the
Chinese consulate staked out.

Ah, but he has

a much simpler,
more viable option.

Any ship

flying a Chinese flag is
considered foreign soil

once it's out of the
contiguous zone,

24 nautical miles offshore.

It's practically untouchable.

Right,

so a value-based
algorithm ruled out

private yachts and cruise
ships and any boat incapable

of making a
transpacific journey.

However, it weighted
heavily towards freighters,

and the Port of Los Angeles

recorded 13 Chinese
freighters as of yesterday.

Do they know my name?

Have they been
watching my contacts?

How much of my
network is compromised?

COLBY: Kirkland never
said, and I never asked.

Is that what Kirkland
said when I asked him?

I know Kirkland.

If you tortured him, he
didn't tell you anything.

That's right.

Quinuclidinyl benzilate...

produces...

akathisia, an intense
desire to move.

It also amplifies
pain receptors...

so that even a pinprick

will feel like you're
being stabbed.

It also causes hallucinations

and a loss of mental
and physical control.

Good.

Then you'll know what to expect.

DAVID: Four Chinese freighters
pulled out of harbor this morning.

The Tian Xi was scheduled
to load bicycle parts

and paper pulp headed
for Vietnam next Tuesday.

Instead, it pushed out
of harbor this morning.

NSA's satellite image is two
hours old, but you can see

she's moving past
the 12-mile mark.

What makes the Tian
Xi really interesting is

the bicycle parts
are being loaded

by the China National
Export Company,

which is on our watch list

as a possible front for
Chinese intelligence.

You see that boat right there?

(typing) Take a look at this.

Actually, you know
what? Do me a favor...

Zoom in on that black SUV.

Yeah. (typing)

I mean, that's a whip antenna,

isn't it? One of ours?

(typing)

Let's see.

Infrared markings.

Run it.

All right, so the car was
signed out to this guy.

His name is Mason Lancer.

He's a Special Assistant to
the Deputy Attorney General.

That's exactly
the kind of position

that would have access
to classified information,

but he'd still need somebody

to go out and steal
what he can't reach.

Yeah, like Carter.

Or Colby Granger.

DAVID: Now, the
ship is 16 miles out.

It's still outside the
12-mile territorial mark,

but it's inside the
contiguous zone.

Which means we still
need a search warrant

from the State
Department if we want

to board.

How long does that take?

Between three
hours and two days,

no guarantee that
they're going to say yes.

Once they cross
the 24-mile mark,

there's no way we
can get on at all.

All right, look, it
comes down to this:

do we, in fact, think
that Colby is a traitor?

That's all it's about.

Do we? And if we do, we
let the Coast Guard watch

and we wait for a warrant.

And if he's not, he
could be dead by then.

Yeah.

Um...

so, uh, th-this is the
trust metric I-I prepared

on Colby Granger.

It's, um,

it's a man's life put down on
a few pages of expressions,

distilled down to an
index of trustworthiness,

which is a single number

that incorporates all
facets of his behavior

like, you know, like
the risks he's taken

or the orders he's obeyed

or disobeyed.

The confidences he's shared.

Yeah, so what does it tell us?

Nothing.

Nothing we don't already
know in our hearts.

I'm in.

I don't know what to believe,
but I'd like to go find out.

All right, we roll in ten.

(exhales)

Do they know my name?

Your name, your dog's name,
your grandmother's name.

Everybody knows everything.

The last syringe is
potassium chloride,

the finisher in a
lethal injection cocktail.

If I can't know what you know,

then it's really best for
me that no one else does.

What it comes down to is...

Do you want to spend the
last hours in unholy pain

just so that you can die?

Granger, don't do
this, it's not worth it

for some secrets
nobody will care about

six months from now.

Dwayne, I really wish

somebody else had
pulled me out of that fire.

Why?

'Cause I hate owing you.

(siren wailing)

MAN (over speaker):
This is the FBI.

Shut down your engines
and prepare to be boarded.

What are you doing?
What I said I would.

(gun cocks, gunshot)

(indistinct yelling)

(gunshot)

(gunfire)

(grunting)

Potassium chloride.

That stuff'll stop his heart cold.
Plunger wasn't fully deployed,

but he's not breathing.

Colby! We got to get a medic.

Stay with me! Wake up!

Let's go!

Wake up!

Colby just keeps
owing this guy, huh?

Only if he lives.
Colby, come on.

Let's go! Come on.

Colby!

We've got control,
but.. Ah, damn!

Colby, you hear me?!

Wake up! Wake up!
Stay with me! Colby!

Doctors say his
vitals have stabilized,

but it'll be a day or so before
the drugs are out of his system.

Until I saw that needle
sticking out of his chest,

I was sure he was guilty.

You saved his life.

I still don't know who he is.

I didn't know him
when he was a spy.

Now he's some guy who
pretended to be a spy.

Who pretended to be my partner.

You coming in?

No... not yet.

I don't feel any the lesser

for a night away from broccoli,

carrots, and coarse grain bread.

I'm stuffed. ALAN: You know,

celebratory food always tastes
better, Larry, don't you think?

Okay, to, um...

Colby Granger and his
rapid recovery, we hope.

Yeah, well, then, in that case,

to Don's instincts.

Yeah, and, uh,
your trust metric.

Sounds like a new
chapter in the, uh,

"Mathematical Analysis
of Friendship Dynamics."

I'm not familiar
with that paper.

That was early Charlie Eppes.

Ah. The mathematics
of friendship.

It was like a self-help
manual for eggheads.

Something like that.

No offense.

(chuckles)

You guys might
be on to something.

Uh, Charlie. Charlie.

Charlie, we were just kidding.

Dust off the old paper,
and convert the playground

to an office, run a
few new expressions.

I could publish anyway.

LARRY: I certainly
laud the attempt

to wrestle order
out of the chaos

of interpersonal relationships,

but how are you going

to address higher
order constraints?

ALAN: Don't egg him on, Larry.

CHARLIE: Heuristics.
Heuristics, of course.

See, no... Everybody knows that.

That's why I didn't get
through it to begin with.

I mean, it's too
complicated... heuristics.
