Numb3rs

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!

Ashby was building a Janus List.

A master list of double agents and traitors.

Welcome to the Janus List.

The following people have been co-opted.

United States FBI agent Colby Granger, by the Chinese.

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

Nothing you don't know.

Nothing everybody's not going to know tomorrow.

David...

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

- Just relax. - 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!

Spying on your own country?

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

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.

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.

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.

Oh, hey. There you are.

Hi.

Your analysis of game theory seems a little bleak.

Oh.

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.

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.

Who else was involved?

Carter was my cutout.

He never let me near his handlers.

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?

It just doesn't seem right.

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.

Delta Three Niner,

confirm for transpo to secure facility two.

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.

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

Dwayne, grab his gun.

Ride's here.

This ain't going our way, Granger.

We got to go.

Hey, get down! Don't move.

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.

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. Yes. 11th grade.

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

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

What?

When?

Yeah, yeah, all right. Uh...

Yeah. I'm on my way.

I got to go.

Why? What's up?

Dwayne Carter and Colby just escaped.

There's gotta be something in here.
