You nearly died when you were a boy.
NARRATOR: Previously on Fringe:
WALTER: l became consumed with saving you.
l don't remember any of that.
-l can't let Peter die again. -What did you mean by that?
l designed a device intended to cross the time-space continuum...
...and retrieve my dying son.
-Walter, l gotta tell Peter the truth. -Things have never been better.
l can't lose him again. l can't.
Give me time to prepare. Please.
[HORN BLOWlNG]
WOMAN [OVER PA]: Next stop, Boston Main Station.
Transfer to the orange line, silver line and all commuter rails.
TEENAGER: Any change?
Excuse me, ma'am, do you have any spare change?
Thank you, God bless you.
Sir? Any spare change?
-No. No, l'm sorry. -Anything you can manage--
Thank you. God bless you anyway, sir.
MAN [OVER PA]: Now approaching on track 1 8, the 331 express train....
WOMAN: Now approaching Boston Main Station.
Spare change?
Oh, God. Oh, God.
No. No, please. Let me out of here! Help!
Let me out of here!
[PHONE RlNGS]
PETER [OVER MACHlNE]: Leave a message.
PETER: lt's Peter, pick up.
Hey, Walter, it's Peter.
Your son, Peter.
Come on, Walter. Pick up the phone. Walter, pick up the receiver...
...and hit the square black button next to the red flashing light, remember?
Fine. When you get this, get your kit together.
Just got off with Olivia, she said there was an incident on a train.
I know how you love trains. Thought it might cheer you up.
Be home to pick you up in 1 5 minutes, all right?
PETER: You notice anything weird?
Not yet, but give it 1 0 minutes.
l was actually talking about Walter.
WALTER: Hello, l'm Dr. Walter Bishop.
He's been avoiding me. He didn't even look at me...
...in the car ride over her. He's stopped eating.
Got him a new box of Peek Freans, he hasn't opened it.
-Did he say something? -No.
All week, it feels like he's been enveloped in this...
...sadness.
l haven't noticed anything.
Oh, my.
Sir. What are you doing?
-Checking their underwear. -Their underwear?
Surely you're familiar that with sudden death...
...victims often experience a sudden bladder release of urine.
And sometimes, excrement.
-Get off this train. -He's with me.
Thank you.
l don't know what happened to these people, Agent Dunham.
My first guess is collective heart failure.
These people died from a heart attack at the same time?
Perhaps it was sympathetic, contagious. Like yawning.
Come on, Walter, you really believe that?
Walter, does your theory suggest why all the lights would be out in this car?
No. There should be battery backup.
Unless it wasn't serviced properly.
Agent Dunham.
BROYLES: Crossed paths with a man as he entered the car.
Six foot, brown hair, wearing a trench coat.
And he's sure that he saw him coming out of this train car?
The man didn't speak to him or acknowledge him.
He just exited down the stairs of the platform.
Did we pick him up on surveillance?
Waiting to get word if they pull him on any footage.
PETER: Agent Dunham.
Hey, Ryan.
Found this over there.
Oh, my God.
Excuse me, gentlemen, that's mine.
Thank you, thank you.
PETER: All the batteries are dead. lt's not just the lights.
This is her cell phone. They're all dead. Cell phones, laptops, mp3 players.
-They're all completely drained. -Any theories, Dr. Bishop?
Oh, no.
Except my initial theory of collective heart failure is probably incorrect.
l'll need to take some of these bodies back to the lab.
Six or seven should suffice.
We have an image from the platform cameras.
Who is this guy?
And how did he kill everything on this train?
WALTER: This is unusual. Dying organisms struggle for their last breath.
These people appear as if their switches have simply been turned off.
-Hey, how's it coming in here? ASTRlD: Hi, Peter.
Not very good.
Take samples of this man's lung, brain, and skin.
-Something's not right here. -Yep, l think it's my paycheck.
Whatever it is, l'm sure you're gonna make sense out of it, Walter.
Walter, what's going on with you?
ls there something you wanna talk about?
No. Everything's fine.
Astro, show me those previous cellular samples.
That's extraordinary.
ASTRlD: ATP concentrations are unusually low.
The process should continue for hours, even after death.
This man's mitochondria ceased functioning...
...well before it should.
What do you say l take samples of the rest?
-See if there's a trend. -See if there's a trend.
PETER: So, what are you saying, Walter?
Something was able to reach inside people's mitochondria and--
Drain them, like the batteries in the electrical devices on the train.
lt wasn't just their hearts that stopped, it was every cell in their bodies.
What do you think could do something like that?
l have no idea.
BROYLES: Twenty years ago, a person walking through Boston...
...showed up on an average of 1 0 different surveillance cameras.
Now, it's hundreds.
-Bad for privacy but good for us. -l asked them to output each source...
...to a different monitor. Give us a sense of the route. Play it.
He exits the train station, crossing Ferris Ave., continuing north.
This is from the bank on Howard Street. Coming around the corner.
There, he enters a cafe.
He spent almost 45 minutes inside, then left the establishment.
Guy kills a train full of people and then stops for a meal?
BROYLES: And the trail goes cold there.
He left the cafe, we couldn't locate him on any cameras.
OLlVlA: But we have a place to start.
Cafe Wilusa.
Yeah, he was here this morning. He comes in all the time.
-Weird guy. -Weird how?
Well, he always draws on stuff. Like the napkins and the placemats.
-Well, what sort of stuff does he draw? -Some kind of math, l think.
To be honest, my higher math ends at calculating my tip. So....
-Does he ever pay with a credit card? -Sometimes he does.
Here. This is him.
OLlVlA: "Alistair Peck."
Thank you, this'll really help.
AGENT 1 : Clear.
AGENT 2: Clear.
AGENT 3: Clear.
Send the Bishops up please.
WALTER: These mathematical formulae are extraordinarily complex.
Physicists use diagrams like these to shorthand ideas...
...about how subatomic particles behave. These are sublime.
This may explain his flourish for numerical wallpapering.
Astrophysics.
He teaches at MlT.
WALTER: lf l comprehend this correctly...
...then this Alistair Peck has taken Einstein's theory of relativity...
...and turned it on its ear.
l grasp portions of it...
...tachyons are depicted here, but l fail to see their relevance.
However, it does confirm that Dr. Peck...
...was dealing with tremendous energy to do whatever it is he's doing.
PECK: What--? What are you doing with my things?
AGENT [OVER RADlO]: Peck is here. He's downstairs.
He just walked in off the street.
Guess that explains what all the surgical tools were for.
What did you do to the people on that train?
Twelve innocent people.
Those people aren't dead, miss.
Not permanently.
-Of course they're dead. PECK: But they soon won't be.
Although others soon will be, l'm afraid.
Dr. Peck, l want you to lie down on the ground now.
PECK: Don't take my computations. They're meaningless to you.
lt is well within my ability to make it so that you are never in possession...
...of things l require.
-You've implanted a faraday mesh. PETER: What are you talking about?
A shield to create a temporal pocket around your body. Of course.
Of course, what? Why would he need a temporal pocket?
-That's fantastic. OLlVlA: Dr. Peck, what are you doing?
Dr. Peck.
-Walter, what's happening? AGENT: Get down.
l said get down on the ground.
Spare change?
l'm sorry you have to go through this again.
Oh, God.
Oh, God. Let me out of here!
PETER [ON MACHlNE]: Leave a message.
Hey, Walter, it's Peter.
Your son, Peter.
All right, fine. When you get this, get your kit together.
Just got off with Olivia, she said there was an incident on a train.
I know how you love trains. Thought it might cheer you up.
Coming home to pick you up in 1 5 minutes, all right?
PETER: You notice anything weird?
Not yet, but give it 1 0 minutes.
l was actually talking about Walter.
Excuse me, l'm Dr. Walter Bishop. ls this the car?
AGENT: Right over there.
Must be the car.
Oh, my.
[lNAUDlBLE DlALOGUE]
Here's the initial report.
Think these people died from a heart attack at the same time?
WALTER: Perhaps it was sympathetic, contagious. Like yawning.
Walter, does your theory suggest why all the lights would be out in this car?
No. There should be battery backup. Unless it wasn't serviced properly.
l'll need to take some of these bodies back to the lab.
Six or seven should suffice.
Agent Dunham.
He crossed paths with the suspect as he entered the train car.
Says the man was in a raincoat.
Six foot, brown hair. Says he touched the railing. We're dusting for prints.
Hi there. The man from the train, did he say something to you?
-Yeah. -What did he say?
"l'm sorry you have to go through this again."
"Again"?
OLlVlA: And what then?
He stepped off the stairs and walked away.
PETER: Agent Broyles, Agent Dunham.
All the batteries are dead. Cell phones, laptops. They're completely drained.
Hey, Ryan.
-Look, found this on the floor over there. -My God.
Oh, thank you. Thank you. That's mine.
-He found it on the floor over there. -Oh, oh.
Thank you.
-The mitochondria were depleted? PETER: Yep, completely drained.
Victims didn't die of a group heart attack, they were drained of biological energy.
-Just like their phone batteries. -Pretty much. "How" is the question.
Walter is still working. l'll let you know if he finds out anything.
-Okay. -Dunham.
We managed to lD the print we lifted off the train-car railing.
We got lucky. lt matched a set NASA has on file.
"Doctor Alistair Peck." What did he do at NASA?
He was classified as part of a think tank.
We don't know much more than that yet.
Well, we know he lives here, 412 lnman Street.
AGENT 1 : Clear.
AGENT 2: Clear.
Send the Bishops up please.
Mr. Peck may have done project work for NASA...
...but he's employed locally.
Astrophysics, he teaches at MlT.
What?
Wow, l'm having deja vu.
Yeah. l read that deja vu is fate's way of telling you...
...that you're exactly where you're supposed to be.
That's why you feel like you've been there before.
You are right in line with your own destiny.
-Well, do you believe that? -Ehh.
No. lt's a bit mystical for my taste.
l never get them myself...
...maybe because l'm not on track with my destiny.
-Huh. Look at this. -What is it?
A photo album.
Okay, but who are you?
What's your name?
Well, one of them's bound to be back sooner or later.
Hopefully sooner.
Shall we go home now?
l'm tired of waiting.
Olivia...
...might l come with you? ln your car.
l can't drive home with him.
-l can't look at him. -Walter. You can't keep doing this.
Peter knows that something's upsetting you.
l've written him a letter.
lnstead of me stammering in fits and starts...
...a letter is more concise.
lt explains everything in just the right words.
Except that every time l think l'm ready to tell him...
...l envision his reaction when he reads it.
l run the scene in my mind again and again...
...and every time, the outcome is terrible.
But l will do it.
But first...
...there's something l'm waiting for, Agent Dunham.
-Something important. PETER: Hey, guys, check this out.
Templates. Forms.
OLlVlA: What are they for?
What you'd use to cast machine parts. These look handmade.
This one is dated several months ago.
This one, even earlier.
He refers to them as prototypes.
But prototypes for what?
BRYCE: Alistair Peck was a professor here for six years.
His focus-- Obsession was particle acceleration.
Creating wormholes without a particle collider.
You're saying Dr. Peck's area of expertise was time travel?
He kept cranking out theories, every one of them was over our heads.
-Must be frustrating for his superiors. -Embarrassing is a better classification.
They wanted to fire Alistair but he saved them the trouble and left a year ago.
ls this his wife?
Ah. The fiancee. Her name is Arlette.
-Do you remember her last name? -l don't recall.
PETER: Do you know any other friends he had? People he knew?
BRYCE: That's the sad thing. He was kind to everyone, but he never socialized.
l think l was his only friend.
Well, anything that you can remember about Mr. Peck...
...it could be important.
BRYCE: Alistair sent me these about six months ago to proofread.
-He had hopes of seeing them published. -Can we take them?
Only gathering dust here.
They are pretty dense. Most would say it's gobbledygook.
Well, l happen to know someone who is fluent in gobbledygook.
WALTER: l'm finished.
Another 20 years, with the assistance of some other great minds...
...l will have absorbed this information.
Alistair Peck has conceived of some extraordinary theories...
...and is possibly implementing them.
Meaning what?
He may well be able to travel through time.
Conceivably.
Einstein himself theorized this.
Ten a.m., 1 1 a.m.
He said that if something could propel an object...
...faster than the speed of light, then time would appear to bend.
When those two folds connect...
...a tremendous amount of energy is required to absorb the jump.
From any power source. So the laptops, the phones.
-And anyone who was near him. -Yes.
What you're saying is Peck's moving through time...
-...is what killed these people. -That is my theory.
Yes, and Olivia, if it is right...
...then we may well have apprehended this man already.
Possibly several times.
l found his fiancee.
The car in one of the pictures is registered to an "Arlette Turling."
Her license information's coming through.
Okay, that's her. Find out what you can. She's our only connection to Peck.
WALTER: The third volume is unfinished.
There's a handwritten segment at the back...
...then the writing stops.
The unfinished chapter is entitled: "Achieving the Arlette Principle."
-What did you just say? -"Achieving the Arlette Principal."
OLlVlA: l think l know why Peck is doing this.
Arlette Turling was killed in a car accident 1 0 months ago.
On the 1 8th of May.
What if Alistair Peck is going back...
...to save her?
Grief can drive people to extraordinary lengths.
Now, considering the amount of energy...
...that was drawn when he landed at the station this morning...
...using Peck's own theories...
...l estimate that we witnessed just a 12-hour jump.
A 1 0-month jump, the results would be devastating.
-Well, how many casualties? -lt would depend where he landed.
Hundreds.
ASTRlD: This is weird.
l did a search for Peck's cell phone when we first lD'd him as a suspect.
He didn't have one.
But Arlette Turling's number is still active.
Someone's paying the bill.
Now, in the past 24 hours, the primary cell tower...
...that's been handling the signal from Arlette's cell phone is a tower near...
-...Albany Street. WALTER: What's near Albany Street?
MlT.
What's he doing at MlT? The professor said she hadn't seen him for a year.
Well, Walter has a lab here, maybe Peck has a lab there.
According to the files...
...the lab registered to Peck when he was professor here was Lab 1 07.
Are there any windows in that lab? Get your men on the rooftops.
-Those guns really necessary? -You okay?
-You want me to take you back home? -No, Peter. No.
-Just stay there. Agent Broyles. -Agent Dunham.
lf we are correct, for Peck...
...this is about bringing a dead loved one back to life...
...then Peck and l, we have something in common.
-Let me speak to him. -Walter.
Of course, l know that killing him...
...is the only way to ensure he won't jump...
...but if l could talk to him, l think l can convince him to stop this.
Please.
Let's talk to Broyles.
Yes.
[TUBEWAY ARMY'S "ARE 'FRlENDS' ELECTRlC" PLAYlNG OVER RADlO]
[GRUNTS]
[PLAYlNG OVER RADlO] lt's cold outside
And the paint's peeling off of my walls
There's a man outside
In a long coat, grey hat, smoking a--
[MUSlC STOP]
Wait. l'm not a threat.
l am an ambassador.
l know who you are.
You're Dr. Walter Bishop. l've read you.
New Frontiers in Genetic Hybridization.
And l know that if you wanted to...
...you could disappear from here in a second.
Please trust me.
You and l both know there are certain things we take for granted.
The laws of nature, for example...
...that are not necessarily binding.
There are places on this Earth...
...where two plus two most definitely does not equal four.
You figured out how to bend time.
But you're only interested in traveling to the past.
Your goal, your next jump, is the 1 8th of May.
So you know.
The 1 8th of May. Yes.
Don't do that. Don't stand there.
[OVER RADlO] There are snipers outside. Stay away from the window.
-l hope he knows what he's doing. PECK: Why are you here?
What do you really want?
My calculations show what you must already know.
An enormous amount of energy...
...will be drained from wherever you arrive...
...and a large number of people will be killed.
-But each jump back clears that slate. -No.
lf you are reunited with your fiancee, and you pull her from that car...
...the victims of this last massive reset will remain dead.
Listen...
...on the day of the crash, we argued.
Arlette wanted me to go to some store...
...to register for wedding gifts.
And l hurt her feelings, then l left.
As l walked, l became drawn to something on the horizon.
A large red ball.
lt was a hot-air balloon, moored on the city's outskirts...
...out in this field.
l spent the whole day in this field...
...looking at this balloon.
And l got my answer.
l had an epiphany of how to physically apply my theories of time travel.
l was in that field the moment her car was hit.
Eighteen May, 2:1 8 p.m.
lf l'd have simply done what she asked me, if l'd have said:
"Sure, l'll go with you"...
...l know it wouldn't have happened.
l will jump back.
But l'll jump back into that empty field, Walter.
And l will only drain the energy from the plant life.
Energy will be dispersed, no one will die...
...and l will pull Arlette from that car, save her life.
l know why you haven't gone back to May 1 8th yet.
Because you don't know how to.
You haven't been able to jump back any further than the train.
[STATlC ON RADlO]
What happened?
Someone get that signal back online.
You approximated the time curvature using a seventh-order polynomial.
But you made one small error. For the distance you require...
...it should be at least nine.
l've read you too.
AGENT: We can't get it back online. He turned the radio off.
Get a team up there now.
l'm telling you how to do this, but l am telling you...
-...you cannot do it. -l must do it.
-You'll never live with the consequences. -l told you no one will die.
That's not the consequences l am talking about.
l, too, attempted the unimaginable, and l succeeded.
l crossed into another universe...
...and took a son that wasn't mine.
And since then, not a day has passed...
...without me feeling the burden of that act.
l'm going to tell you something...
...that l have never told another soul.
Until l took my son from the other side...
...l had never believed in God.
But it occurred to me...
...that my actions had betrayed him.
And everything that had happened to me since was God punishing me.
So now l'm looking for a sign of forgiveness.
l've asked God for a sign of forgiveness.
A specific one, a white tulip.
Tulips don't bloom this time of year, white or otherwise.
But he's God.
And if God can forgive me for my acts...
...then maybe...
...it's in the realm of possibility...
...that my son possibly may be able to forgive me too.
Walter, God is science.
God is polio and flu vaccines and MRl machines and artificial hearts.
lf you are a man of science, then that's the only faith we need.
Allow me to serve as a cautionary tale.
There will be repercussions.
lf you pull Arlette from that car...
...you don't know how things will be changed by your action, but they will.
lt's not our place to adjust the universe.
And you'll never be able to look at her again without knowing that.
Just like every time l look at my son.
l have traveled through madness to figure this out.
And you will too.
You're asking me to just leave her there.
[BANGlNG]
No, no, no. No, stop, l'm all right.
Gentlemen, please. Gentlemen. You see, we won't remember this.
Don't you see? We won't remember anything--
OFFlCER: Officer in need of backup.
WOMAN [OVER RADlO]: Copy that, what's your 20?

This is weird. l did a search for Peck's cell phone...
...when we first lD'd him as a suspect.
He didn't have one.
But Arlette Turling's number is still active.
Now, in the past 24 hours, the primary cell tower...
...that's been handling the signal is a tower near...
...Albany Street.

Alistair Peck is back at his residence. Six dead.
lncluding two Boston P.D. officers.
We have to take him down before he jumps again.
[SlRENS WAlLlNG]
SNlPER: I have a shot. -Take it.
[GUNSHOT]
[lNAUDlBLE] So you decided to come with me?
I love you.
I love you too--
l haven't seen you look at that letter for a while. lt's been almost a year.
Today's the day l'm supposed to send it.
Open it.
Apparently, Alistair felt whatever it is, he could put in your trust.
He wouldn't have sealed it if he wanted me to see what's inside.
[DOOR OPENS]
Hey, Walter. Hey, l got you something.
Fixed your turntable.
l'd tell you to keep it out of the lab, but you won't.
Thank you, Peter.
Thought maybe you'd like some music to cheer you up.
Walter, l know that you've been in a funk for the last couple of weeks.
-lf there's something you wanna talk-- -No.
Something was weighing on me.
A decision.
l'm fine.
Okay.
l'm gonna go hit the hay.
