Numb3rs (2005–2010): Season 5, Episode 11 - Arrow of Time - full transcript

Buck Winters, who murdered and stole with his older lover in the season three premiere, escapes from prison and comes after Don. Don uses his newfound faith to guide him through.

CHARLIE: Entropy...

A measure of randomness;

a parameter of disorder;

energy broken down
in irretrievable heat.

(man singing in Hebrew)

What might appear to be chaos,

even decay, is
really a system's way

of smoothing out differences;

its search for equilibrium.

Too florid?

For 30 overachieving
grad students? Probably.



But for me...

Tell me more about
irretrievable heat.

Where language might fail us...

the poetries of math
and physics bring clarity.

Observing spontaneous changes...

in isolated systems.

♪ I see the rifles
coming over the hill ♪

♪ And if you shout, maybe
they stop and won't kill ♪

♪ But if you think like me,
you'll be as dead as he... ♪

(alarm blaring)

♪ I see the lion
crawling over your bed ♪

♪ And if you stay... ♪

Entropy is our yardstick

measuring progress,



defining the
boundaries of a story,

a beginning and an end.

Entropy has the unique ability

to choose a particular
direction for time.

The Arrow of Time.

The Arrow of Time.

♪ I see more
color in your eyes ♪

♪ Than the reflections... ♪

Uncorrelated parts interact

and find their connections
in an evolving system.

♪ I see the rifles
coming over the hill ♪

♪ And if you shout, maybe
they'll stop and won't kill ♪

♪ And if you think like me,
you'll be as dead as he ♪

♪ Some day ♪

♪ I see the color
in your eyes... ♪

So, from one perspective,

entropy is a clock,

charting the irreversible.

♪ ...The world as your side. ♪

Looks like an arrow
pointing straight back to L.A.

Nice of them to leave
us a trail of bread crumbs.

OFFICER: Hey, Sinclair.

Hey, Joe.

What do you need? Great big net.

Got three men over the wall.

Had a car waiting.

Tire tracks say

older model, long wheel base.

Well, that narrows it down.

Unless we hear reports
about three bad-asses

terrorizing the countryside
in their underwear,

count on a change
of clothes, too.

So, they already made it
past the roadblocks, huh?

JOE: Long gone.

Look at this here.

Oh, looks like...

Dental floss.

LIZ: How the hell did

they get that much dental floss?

Well, that's a very
good question.

They must've had a lot

of time on their
hands. "They" being...?

Well, that is why I
dialed you in on this.

WOMAN: Hey, Ugly!

Ugly? Uh, yeah, that's Ugly Joe.

There's a Big Joe,

Little Joe and an Ugly Joe.

There's a bigger Joe?

No, an uglier one.

(sighs) Damn.

NIKKI: Buck Winters.

Tell me about the other two.

Gray McClaughlin.

Doesn't look like he's
had any time to commit

a crime where he
didn't get caught.

Started off low-level
drug dealing.

Couldn't make that work.

Yeah, I just read something

like 95% of small businesses

fail their first year.

He's not a bad-looking cat.

Really?

Oh, but when you
guys notice, it's okay.

DON: All right, come on.

Next.

Uh, Rafe Lansky.

He's an Aryan-looking
individual,

but he's pretty
ethnically enlightened.

He freelanced for
the Colombians,

the Jamaicans,

the Russians... DON: As?

Hit man... dropped at least

six bodies we know of.

OC moved four others into
the "pending inactive" column

as "likely but unprovable."

DON: Anything with
known associates?

I just got the files, boss.

DON: All right.

It's a fugitive case
just like any other.

You know, any other
case, the first thing I look at

is the guy who shot his wife.

Go to the second.

Okay.

DAVID: Buck
Winters, 17 years old,

hooks up with his
teacher, Crystal Hoyle.

Buck's father already
beats the crap out of him

on a regular
basis... He finds out,

he beats some more
of the crap out of him.

Buck killed him

for trying to keep them apart.

Pit bull puppy love.
Buck and Crystal

rob and shoot their
way across the country,

get married in Vegas.

LIZ: Because,
really, who doesn't?

These are two seriously
fearless individuals.

They robbed a meth
lab and blew it up.

We caught Buck, and Crystal
retaliated by kidnapping Megan.

Megan Reeves.

This is that case?

Don never talked to
you about any of this?

No.

COLBY: When Hoyle took Megan,

Don lost it... Some
things happened

during his
interrogation with Buck.

NIKKI: Things like...?

All I know is Don got the
information he needed,

Buck went to the hospital,
and we got Megan back.

Crystal Hoyle went
down shooting.

Actually, she drove
at our roadblock

with a carload of hand grenades.

Don's the one that
pulled the trigger.

NIKKI: Just another day in the
exciting field of crime fighting.

Why is Don acting like
he did something wrong?

Just, sometimes,
this job forces you

to ask yourself some
really hard questions,

and I guess that was one time

Don just wasn't
ready for the answers.

The kid threaten Don?

He didn't have to.

I'll take Lansky.

Why don't you take McClaughlin?

Unless, of course,
you think you're

gonna lose yourself
in his deep brown eyes.

Oh.

Hey. I thought
you snuck out early

to work on your lecture.

You guys remember
that idea I had

for finding a complex
polynomial encryption?

Withers just patented it.

It wasn't Withers.

It was his collective.

In fact, I think
a civil engineer

suggested attacking it
through Riemann's hypothesis.

LARRY: Yeah, I'm sorry.

Color me stodgy,
but these attempts

to manufacture
insight by committee

run counter to the entire
history of great thought.

AMITA: There are
plenty of instances

of great thought coming
in the works of groups.

Uh, Pisarro, Monet and Degas.

Wedgewood, Watt and Darwin.

Oppenheimer, von Neumann,

Wilson, Weisskopf.

The neo-Confucians. Okay, fine.

Go ahead, pelt
me with specifics.

Hey, we should start
our own think tank.

You know, once a month.

Anything anyone comes up
with, we all... everyone shares in.

Well, I don't know why

I didn't suggest
that in the first place.

We could get Osaki

for chemistry, Galuski for that

down and dirty
engineering perspective.

You know who would add a
fresh dimension of thought?

Who? Your dad.

LARRY: Hey.

Certainly.

35 years of practical experience

in urban planning,

but that fresh
eye of the student.

CHARLIE: Yeah.

I don't think so.

So...

who wants to talk dental floss?

NIKKI: Gray McClaughlin
has a girlfriend.

Deanne Drake.

Yeah, visited him 12 times

in the last 18
months... And marshals

are staked out at her house,

tapped her
phones... no activity.

I got a work address.

Figured we could
go shake her up.

Pier 16, huh?

And she is?

Forklift driver. Huh.

McClaughlin really
attracts the, uh, girlie,

super-feminine types, huh?

So, how did she, uh, meet
this "good-looking cat"?

Prison pen pal Web site.

Insert your next joke here.

Oh, no. No way I
squander this opportunity.

I figure I'll toss a few
ideas around with David,

make sure we really
get this one right.

You do know I'm never
gonna share again.

(elevator bell dings)

Hey, Nikki just found a known
associate of McClaughlin's,

figured we'd...
Yeah, that's good.

DAVID: It's 30 feet long.

AMITA: Floss is sold
in containers of 20

to 150 yards.

I'm an informed shopper.

CHARLIE: Eyeballing the density

of this rope, I'm thinking

it's got to be 18,000,
maybe 19,000 feet.

LARRY: Three and a
half miles of dental floss,

even assuming an average
container size of 50 yards.

127 rolls of floss.

LIZ: You guys find
new and special ways

to freak me out all the time.

DAVID: 127 rolls of floss,

which is a restricted item

in prisons for
this exact reason.

LIZ: Yeah, well,
this and the fact

that it's a great way to slice
through someone's jugular vein.

Ew...

Well, I mean, we could
apply a simplex algorithm.

The time it took
to build a ladder

based on the difficulty

of access.

LARRY: They had limited time

to work on it, when
the other prisoners

and the guards
weren't watching them.

AMITA: And they'd
have to find a way to hide

the containers, throw them out.

So, some floss math

tells us when they
get started, so it might

say something about...

where they're going... what?

"Floss math."

DAVID: Okay, so we're
talking about at least months

of planning; Buck
Winters... He was all impulse.

The other two...

eh, they're no
masterminds, so...

Buck Winters?

Don didn't...?

You know, it all,
it all went down

last night so I'm pretty sure

he doesn't even
know you're up yet.

So...

I just saw the teletype.

Yeah, the marshals dialed us in.

All right, let's just assume

the requisite stoic
Don Eppes posture.

You lock up enough
of these guys,

sooner or later, they get out.

Don, this kid
breaks out of jail,

he makes a beeline
straight towards you

and he doesn't even
bother to cover his tracks.

He's just another fugitive.

You know, we hunt him down

and we put him back.

I hope you're just lying
to me, and not to yourself.

Come on.

COLBY: Deanne Drake?

Yeah? NIKKI: FBI.

Hell, no.

How about a hand, please?

Punch her. She's a girl!

Girl must mean
something different in Idaho.

Okay, hand, please?

And something to
remember when that

next funny remark
comes in your head.

Got your Glock nines,

Walter P .22,

Beretta .25,

If you're going in close,

drop a silencer on this puppy,
and you're like a whisper.

Dan Wesson .357

Now, this is six shots,

but what a six.

Feel that metal on your hands.

Whatever you want.

Desert Eagle 50-caliber.

That thing's
bigger than you are.

DEALER: Man's not lying.

That's a whole lot of gun.

(clicks)

BUCK: That's fine.

We got a whole lot of plans.

You got nothing to hold me on.

How about a stolen Cadillac
you left outside the prison?

I drive an F-150.

Deanne, come on, you watch TV.

When we find it, you so much as

sneezed in that car,
we can DNA match

a booger off the dashboard.

You really want to go
down that road with us?

Accessory to escape is 10 to 15,

especially if you
look like a bad citizen.

And so far, you don't look

like a good citizen.

And look, you are not

the first woman to throw
away a good life on a bad man.

You put it out
there, I get that.

You have to put
it out there, right?

But you drew a creep.

You think I didn't know?

Deep down?

I mean, he's a looker,
but he's no actor.

He's got this...

way about him.

The way he looks
at you, it just...

How'd you get the floss in?

What?

The dental floss.

He wanted a car,

three changes of clothes...

Wait...

What? Dental floss?

She says she set the car,

but she doesn't
know where they are.

Okay, write it up.

Hey, boss?

Look, for what it's worth,

I think you did what you
had to do with that kid.

You know, you made
some hard choices,

but you were on the
side of the angels.

Hmm.

So, has California Corrections

given us more details
on trash procedures?

No, I'm still waiting.
One has to admire

the ingenuity at work here.

I mean, creating the
unexpected out of the mundane,

I mean, it's like
Robinson Crusoe.

Professor on Gilligan's Island.

Similar circumstance.

Necessity plus
freedom from distraction.

Oh, I don't know,
there was Mary Ann.

Smart man, staying
away from Ginger.

LARRY: Hey, speaking
of choosing one's words,

have you spoken with Don?

Uh, if he wants to
talk about this case,

he'll get around
to it, you know?

How about you?
How are you doing?

This must bring up some stuff.

Megan's kidnapping...

Um...

Yeah.

Ah, yet again,
male communication

tests the limits of Shannon's
source coding theorem.

Granting you that,

I will inelegantly
reintroduce the idea

of bringing Alan
into the think tank.

Uh, yeah, sure...

because he and I don't
spend enough time together

under the same roof,
or at the same school.

Okay, I was seven years old,

and I asked my dad
if he could help me

figure out a good estimate

for the remainder term
in a Taylor expansion

of the hyperbolic cosine.

Our eyes met

and there was this...

tacit understanding that
we had crossed the Rubicon.

When you're seven years old,

your dad should
be seven feet tall.

So, I separated
math from my dad.

As irrational as it sounds,
I'd prefer to keep it that way.

Oh, I'm just surprised that you,

uh, even have time for me today.

I mean, uh, what with
Buck Winters on the loose.

Well, you know, there's this
thing called the Internet now.

They give you the news.

You don't have to
worry, Dad, it's all all right.

That's a fairly
ridiculous statement.

I know you're, uh, capable
of taking care of yourself.

What bothers me is this, uh,
strange detachment of yours.

That's what this looks like?

Really?

Detachment?

I'm your father,
I can't help it.

I just, um...

I'm, uh...

scared.

Look, I'm scared
that if I go out there,

I'm going to have
to kill this kid.

Eight to nine months.

That's it? No
bells, no whistles?

CHARLIE: Oh, no,
I mean, I tracked

the rates of floss being
stolen from the infirmary,

allowed for

parallel escape
plans, blah, blah, blah.

But ask me what's really
interesting about this rope.

Charlie, what's
really interesting

about this rope?

Boy, I'm glad you asked.

Floss is generally fabricated

from bundles of nylon
or Teflon filaments.

It's produced in different

decitexes and thicknesses.

Which makes some brands
stronger than others. And sharper.

You know, you build this
rope with the wrong floss,

it's not going to
sustain body weight,

or it's gonna cut your hands.

Lab had the same idea.

They didn't find any blood
anywhere on the rope.

Exactly. You know,
all my models indicate

that there was
no trial and error,

so, this rope wasn't built;

this rope was engineered.

Which requires a certain
amount of aptitude.

Expertise.

Which is none of our three guys.

Excuse me.

Hey.

Hey. What's up, bro?

You don't write, you don't call.

You know how it is.

I thought David
was filling you in.

Yeah, he filled us in.

Dental floss.

So, we, uh, found an
interesting, uh, connection.

All right, good.

(knocking on door)

Tim Pynchon?

FBI.

It's the shoes.

This 'cause I, uh, celled
with Gray McClaughlin, right?

Until 10 months ago, yeah.

Yeah, hit the DNA lottery.

Thank LAPD

for mislabeling evidence.

You can do a phone dump,
toss my capacious abode.

Seems like a long way down

for a guy who's used to pulling

six- and seven-figure takedowns.

Yeah, I guess high end
burglaries don't really

prepare you for the
contemporary job market, do they?

It's all computers these days.

DAVID: Yeah,
well, you do strike us

as the kind of guy
that would put together

a bulletproof escape plan...

Design a rope ladder
out of dental floss.

You know who doesn't
strike us that way?

Gray McClaughlin? Rafe Lansky?

Buck Winters?

You guys gonna give
me some love if this is

a "what if" conversation?

Well, I'd say that
depends on the “what if.”

What if a guy is looking at 15

for a Bel Air vault
he didn't blow?

Spends two years
figuring his way out.

As an intellectual exercise.

DAVID: Does this guy
include his cellmate

in this “intellectual exercise”?

Kind of rude not to.

So, what if he finds out

he's going home and
his cellie offers him

5 G's for the plan?

Where's McClaughlin
come up with five grand?

He used to deal with
a guy named Nestor...

Ruiz, Luiz...

That's the kind of guy
that might hide him out

in this “what if” scenario.

So, how many things about
that conversation didn't you like?

Well, aside from cooperating

before we even got in the door,

confessing sideways
to two felonies,

then pointing us in the
direction of another guy?

Yeah, aside from that.

A six-figure safecracker

uh, he risks his
dumb luck release

for pocket money.

I think I'm still kind of stuck on
that comment about my shoes.

I'm standing here hoping
that a 19-year-old boy

is gonna get himself
stabbed in a bar fight

or OD in an alley.

I once stood not far from here,

wishing a similar end
to the woman he loved.

Because she threatened

someone I cared for.

Made me feel... just helpless.

I came to realize that if her
actions seemed unfathomable,

her motives weren't.

I don't want to know why
that kid is the way that he is.

Well, in cosmology,

the Arrow of Time points
in the direction of expansion;

and if the universe decides
to contract one day...

The past is going to
come looking for us

whether we want it to or not?

Well, cosmologists argue

that the future will continue
to move in the same direction.

But perhaps the universe has...

a more open mind.

I wish Pynchon would
make a move already.

Which apartment
are we staring at?

Up the stairs,

hallway on the right.

Hope you girls didn't have
any big plans for tonight.

Nah, just this photo I
got to e-mail to Idaho.

And that would be him.

Where's he going? There's
an exit up on the third floor

in that middle archway.

It dumps out on Loma.

(engine starting)
All right, got it.

(door opens and closes)

Think he went into
another apartment.

NIKKI (over radio): Forty.

Borrowing a cup of sugar?

Borrowing the landlady?

LIZ: There's a
window on the street.

We're gonna go check it out.

PYNCHON (muffled): We've
got to get you out of here.

First, the landlady's
asking questions,

then the FBI is here.

Cops!

LIZ: Shots fired.

They're coming your way.

(groaning)

(gun clicking)

You all right? DAVID: Yeah.

He was kind enough
to break my fall.

Good for him.

(phone ringing)

Eppes.

We have McClaughlin.

(phone ringing)

Yeah,

keep me posted.

Eppes.

BUCK: Do you know who this is?

Yep.

Then you know what I want.

So, Winters called
you from a burner cell.

Untraceable, but if
he calls you again,

the tech boys'll try
and get a triangulation.

Okay, thanks.

Two minute and 38
second conversation.

What'd you two
fellas talk about?

About what you'd expect.

I'm trying to figure out

if this is eating you up
or you're being a tool.

It can't be both?

Put everything else aside, okay?

You've got an
office full of people

who are trying to take
down two escaped killers.

And it'd be pretty screwed-up

if our biggest
obstacle was our boss.

I'll try to stay
out of your way.

NIKKI: How'd you get
Pynchon to hide you out?

You stare at the same walls

and you hear the same
stories for 23 hours a day,

and so I tell Pynchon
about some drug stash

that the cops didn't
find on my last pinch.

This is when he finds
out about Nestor?

There isn't a Nestor.

It's a jail story... you know,

hidden drug stash, buried
pirate treasure... same difference.

I tell you, for a smart
guy, Pynchon believed

what he wanted to believe.

You know?

He got obsessed,

started planning his way out,

and then after he
jackpotted that appeal,

he got obsessed
with me getting out

and leading him to
the buried treasure.

And you strung him along.

Uh, him and Deanne.

Is anyone really surprised
by my lack of character?

And Buck and Rafe?

Guys like those,

you go your separate way

as soon as you can.

And where's their separate way?

I have my theories.

NIKKI: Such as?

Such as...

what kind of deal
are we going to make?

ROBIN: Here's your deal.

Accessory after the fact.

To what?

Everything... you
facilitated an escape,

which means that you
are culpable for every crime

that I can prove as a
result of that escape.

Winters and Lansky...
They steal a car?

It's on you.

They rob a bank?

It's like you were
driving the car.

They kill a federal agent?

I got good seats in the
gallery, watching them cook you.

ROBIN: Go ahead, doubt me.

Put your little jailhouse
law degree against mine.

And then take a look at
the clock and try to figure out

how many more crimes your
partners are putting on your tab

while you sit there
and don't talk.

Buck wants to kill some
cop, but Rafe doesn't want to.

Buck the alpha dog?

When the kid made
a deal with Rafe,

everybody figured that, you
know, it was what it was...

Fish staying alive
behind some muscle...

But then after
a while, you just,

you couldn't tell anymore.

Was it love, maybe
something else?

So where are they?

Starline Motel.

At least that's where they were.

All I've got in my trunk is
a blanket and a flashlight.

Looks like, uh,
you're hunting bear.

No, uh, actually, I like bears.

You know, Mr. Eppes, it's
not a good time right now.

Don's kind of busy.

Yeah, yeah, I know, I know.

Um...

Um, David...

you've known Donnie
longer than anyone.

Y-You know, um...

I...

I-I didn't do everything
right, you know.

You'll see, when you have kids,

i-it's practically impossible
to get everything... right.

But I think that I-I've...

Don't worry.

I'll take care of him.

Okay?

Okay.

Hey.

Ah, Viterbi algorithms.

Hey, I thought you said
they were for suckers.

I had this idea about predicting
Buck Winters' next move.

It sort of drifted a bit.

Tell me it isn't right.

Hey...

Have you spoken
to Don about this?

No.

But I'm going to.

Hey, Sinclair, nice of
you to invite us this time.

LIZ: So, it's room seven.

Manager's pretty sure

they're still inside.

Because? He knocked
on the door this morning

for, quote: one big-ass fight,

end quote; and Buck answered,

apologized, gave him
a 50 to forget about it.

LIZ: Their car is still
parked in front of the unit.

'75 Caddy, comes back stolen.

All right, so...

this unit here,
bathroom window here.

THIBODEAUX: Here, back here!

COLBY: Looks like
Buck broke his heart.

Hey, so, um...

there's this thing called
a Viterbi algorithm.

It's a way of finding the
most probable sequence

of hidden states.

Hidden states.

There's a guy, he
does three things...

He sleeps, he
eats, and he hunts...

And he chooses which one
of those three things to do

based on the season, the
time of day, and the weather.

Now, if we can only see this
man and know what he's doing

at a singular moment,
frozen in time,

what the Viterbi
algorithm does is it tells us

what the whole world
looks like at that moment.

I used a similar approach
with Buck Winters.

I tried to predict his actions,

specifically those that could
be inferred by the states

of "Buck hiding from the
cops," "Buck with a gun"...

"Buck trying to kill Don."

You already know where
to find Buck Winters.

Why didn't you call me when
you found out he escaped?

I don't really see
much math here.

Five years down the road,

you still don't realize
that there's always math?

What the hell is wrong with you?

I didn't have a
choice with Crystal.

I think about this sermon
I heard the other day,

this, uh... verse they
were talking about...

The natach lach.

At least the way I
understood it was...

You know... "What's
in your hand?"

What are the things
that you can control?

Hey, how are you controlling

the situation by
shutting me out?

In perceptual terms,

memory can only be increased
as correlations increase.

You understand?
That the Arrow of Time

can only take you from
the past to the future;

that what you do tonight,
what you do tomorrow...

It won't put the bullet
back in that gun.

You ought to think about
what you're about to do.

Think about the regrets
you'll have two years from now.

There's auto glass all
over the curb out back.

Looks like Buck
stole another car.

Well, crime techs think
Rafe was cold-cocked,

dragged to the
bathtub, and shot there.

Sure, then he climbs
out the bathroom window

so the manager doesn't see him;

steals a new car so
he's got a head start.

Recovered Winters'
burner from a Dumpster

four blocks away.

I think he was
watching us hit his room.

He was waiting for Don.

You start a dump? Already on it.

In the meantime, we
pulled the last few numbers

off the memory.

You gotta see this.

That's Don's cell.

Why didn't he...? That number
is incoming, not outgoing.

Don called Buck.

Buck calls you through
the FBI switchboard...

you guys speak for
two-plus minutes;

you tell us, nothing
but B.S. threats.

I say, okay.

You ever think to mention he
gave you his phone number?

That motel lead came
in, he'd have been there,

we wouldn't be having
this conversation.

Well, here we are...
having this conversation.

You called him.

You called him out.

You scramble a
five-man tac team.

You tell the marshals...

You don't get to do that.

You can't play
it off like you got

some kind of clear
head about this.

Taking the back seat,

sleepwalking your way
through this investigation...

You know, I kind of get that.

Don!

You withheld information.

You got two choices.

You can turn me in,
or you can let me lead.

What are you doing?

Even on your darkest damned day,

you never pulled any kind
of High Noon crap like this.

Listen to me.

Whatever you see,
whatever goes down,

nobody moves until I signal.

Mm-mm...

Whatever you see.

I told your father I
would keep you alive.

You will not make
a liar out of me.

Well, word around Cal Sci
is that tomorrow's hot ticket

is a lecture on
time-reversible chaotic systems

by Professor Charles Eppes.

CHARLIE: Right, uh...

Although, I think earlier today,

I may have argued against
my own point with Don.

Metaphorically speaking, anyhow.

I guess I'm sort of stuck
on the Arrow of Time.

You know, I had
a related musing.

Clearly, we are

circling around some
underlying truth here.

Don versus entropy.

Where's Maxwell's
Demon when you need him?

Maxwell's Demon?

Yeah, you know,

the man who stands
alone at the door,

between two adjoining rooms.

The temperature and
the pressure are the same.

It's a perfect state
of equilibrium.

(door squeaking)

I've got him.

SOG Bravo has the shot.

Stand by.

Stand by for what?

Don's calling the
signals on this one.

CHARLIE: Each time the
Demon opens the door,

he admits only the
molecules that he chooses,

heating the one room

and cooling the other.

It's a direct violation

of the second law
of thermodynamics.

COLBY: SOG Charlie,
we have the shot, too.

10-4. SOG Charlie.

Everyone stands by for my call.

CHARLIE: So, the Demon not
only opens the door to two rooms,

he allows for the possibility
of perpetual motion.

Should have a gun in your hands.

Unless you came here to die.

And the rearranging of
everything we know to be real.

I loved her.

I know you did.

You made me betray
her... and then you killed her.

SOG Bravo has a
visual on the gun.

SOG Charlie... We
have a clear shot.

Everyone stands by for my call.

BUCK: I wake up every day

and think about
how I failed her.

I sold her out...

for some bruises
and broken bones.

I was weak.

I had to get strong.

You did that for me.

You and Rafe.

Is that why you killed him?

I killed him because
he was afraid to die!

You're not truly
hard on the inside

until you're willing to give
up everything that you love!

To give your life away.

He never realized that my future

wasn't his to decide.

Or maybe he figured it
out in the last few seconds.

I don't know.

You've got three
seconds to go for it.

It's not going to
be that way, Buck.

DAVID: Adam and
Charlie, we're going in.

Bravo, hold your position.

That's 180 bullets
looking at you.

You're not even gonna get
that thing out of your belt.

You think I care?

Two years planning this,

and you let me choose
the time and place?

I know you care.

You didn't come
here for a fair fight.

You didn't come here to kill me.

You came here to die

the same way Crystal did.

I had to kill her, Buck.

I don't have to kill you.

Why?!

Why can't you do this for me?!

You owe me this!

I'm 19 years old!

They gave me 250 years!

You don't know what that's like.

To have to pay for things
that I can't take back.

Yeah, I know what that's like.

(wry laugh)

That's just life.

You want to die?

That's your choice.

But you don't get to
decide how I live with it.

(sobbing)

(screaming)

(sobbing)

Well, that's like just
so much hokum, isn't it?

Hokum...

ALAN: Well, I mean,
Maxwell's Demon

is a thought experiment, right?

Yeah. Well, granted, there are

theoretical applications,
I'm sure, but, um,

when the window breaks,
the cold air still rushes in.

Gears fail, oil leaks.

Sooner or later, that
engine is gonna break down.

(Buck wailing)

I know that wasn't easy.

You know, most days,
I wouldn't think twice.

No.

Not easy.

Hey, Dad, a bunch
of us at Cal Sci

were talking about putting
together a think tank,

which is, you know, just a
group of us getting together

once a month and
kicking around ideas, and...

we were wondering if
you might be interested

in joining our group.

You know, I still
remember the time

when you asked me
for, um, an estimate

on the remainder term

for a Taylor expansion
of the hyperbolic cosine.

AMITA: That's a very specific

memory, Alan.

One never forgets
the moments when

one realizes that
he has nothing left

to teach his seven-year-old
son about math.

Well, yeah, but...

look at everything else

you've taught me
about since then.

I think you've just given me
another very specific memory.

To our new venture.

And to the causal Arrow of Time.

(mugs clinking)

LARRY: Within the
small sphere of our life,

we can stare into the past,

but only our future
is within our control.
