There is an infinite number of universes.
In each of them, there is a version of us.
Previously on Fringe:
Just because you walked in my shoes, don't you think that you know me.
Maybe you are just incapable of trust.
Coming from the person who stole my life.
I've torn holes in both the universes...
so that we can begin to work together to fix...
You were right. They don't remember Peter.
He served his purpose.
The timeline has been rewritten, and yet traces of him continue to bleed through.
He was here and then he was gone. I saw him.
Tell me about the day the picture was taken.
I think I was 6 years old.
We'd go camping in the White Mountains in the summer.
Who took the picture?
My mom.
I remember she was laughing.
Did you have a good relationship with her?
I miss her very much.
Ah-ah. Ah.
Let's go back to the picture.
And tell me what else happened that day.
- We begged her... - Take your time.
It's almost over.
My brothers and I, we begged her to keep it.
We wore her down.
She said yes.
We named him Fred.
How did that make you feel?
Happy.
Let me tell you about them.
They're horrid creatures.
Vile.
Part organic tissue, part machine.
Just like everything from over there.
They're loathsome.
Hateful.
- Contemptible. - Contemptible?
Is he doing the synonym thing again?
Uh, he was telling me about the shapeshifters.
Now he's moved on to the other universe in general.
Immoral. Evil.
Walter, we have been over this. What is in the past is in the past.
We have agreed to move forward.
Even I don't have drugs strong enough to forget...
they kidnapped Olivia to the Other Side.
- They did? - For weeks, that awful woman...
pranced around my lab.
- Awful woman? - Uh, the other Olivia.
- The one from over there. - Oh.
She bought my ignorance with baked goods...
while she carried out her plan to steal pieces of the machine.
With that damned Portuguese sweet bread.
- The machine that created the bridge? - Yes. But that was not their intent.
What they expected was for our world to be destroyed. Annihilated.
Walter, it did not happen.
That doesn't mean that I have to like them.
There's another mirror in the back storage cabinet.
Kennedy, help me.
Lincoln.
- Thank you. - No problem.
Quickly.
- Morning. - Hi.
What's with the redecoration?
Walter.
Hey, don't look at me like I have some reasonable explanation. It's Walter.
- Is Lincoln here already? - Mm-hm.
You did tell him he could come by to learn about shapeshifters, right?
- But I didn't think he would beat me in. - Well, he just lost his partner.
Plus, he is new in town. He doesn't know anybody.
He's probably a little lonely.
No.
- Not going to happen. - Why not? He's cute.
If I went out with him, I'd start having second thoughts, like I always do.
And then he would get hurt and my workplace would become awkward.
You know what? He's not even my type.
Do you ever think that maybe your type just doesn't exist?
Dunham.
I'll be right there.
Twenty-three victims we know of. All following the same MO.
He drills in the back of the skull to access the brain.
The tissue was punctured and exposed to localized electrical charges...
but that's not what killed them.
The official cause of death, cerebral hypothermia.
A chemical agent was used to lower the brain's temperature.
They froze from the inside out.
Twenty-three murders. Why haven't I heard of them?
Because these crimes weren't committed over here.
We've been asked to assist on this case.
Is that gonna be a problem?
Initiate scan.
Scan complete.
Twenty-two murders. Killer didn't leave a single clue.
Then, on the 23rd, we found a stray hair. DNA led us to John Louis McClennan.
No prior arrests. His show-me is up-to-date.
Once we ID'd him, we went to his house, ready to apprehend him...
but he didn't show up. He's disappeared.
- He was ahead of you. - With a 220 IQ, I imagine way ahead.
Five years we've been looking for this guy.
He was sloppy once. He's not gonna make the same mistake.
So, what do you need from us?
We need you to escort the John Louis McClennan from your side over to ours.
Why?
To what end?
We're hoping that he can give some insight into our Mr. McClennan.
- I understand they have... - I know all the reasons not to do this.
I've been through them with my own Colonel Broyles.
Frankly, we got no options.
Okay, well, why don't you just interview him over here?
We want him to see where the killer was living.
If he can, uh, interact with the space, study his belongings...
he can glean something that we can't.
- You hope he can. - Well, I lived in your apartment...
and I picked up a lot of things about you.
Will you excuse us a moment?
Okay, I get it, the accord was necessary, but this is different.
- Stop. - Saving people's lives is important...
but, I mean, have we even thought this through?
- How can we both...? - It's really not that complicated.
Chain of command is simple. Over here, we're in charge. Over there, they are.
It is only simple if there's trust. What about that tech we gave them...
that we took from the shapeshifter? Have we heard back?
Their Science Division is still working on it. I haven't forgotten about that.
Look, I know this is difficult for you.
If there was any other way to execute this, I'd ask someone else.
How is this even gonna work?
Are we prepared to start telling civilians about the parallel universe?
No. Professor McClennan won't have to know where he's being taken.
He's a professor? And over there he's a serial killer?
And we're counting on similarities?
On our side McClennan teaches forensic psychology...
at Western Connecticut College. His area of study, serial killers.
Look, I don't know if this is gonna work...
but maybe it's not so far-fetched, either.
Uh, I'm surprised. You read my article.
I'm working on a follow-up, actually.
I don't think that we can underestimate the role that empathy plays...
in the structuring of the self, or the lack thereof.
I've profiled before for law enforcement...
but I should say that this is the first time with the FBI.
Are you willing to participate?
Agent Dunham, I've been working towards this my entire life.
There's a reason that we've kept this out of the media.
- This case is highly classified. - Okay.
One of the things that you are not able to know is where we're going.
Do you have any allergies to tranquilizers?
What happened to blindfolds?
It's a long journey. I assure you, it'd be more comfortable this way.
No. No allergies.
Come in.
This is Agent Bergmann. He'll be administering a mild sedative.
Ooh. Here's to intrigue.
Okay, thanks.
- Are we wired? - Good to go.
- Hey, Liv, it's me. - Yeah, come in.
- What do you think? - Blond looks good on you.
Yeah, well, lucky Frank likes the red, huh?
I didn't say I didn't like the red.
- You look good in both. - Thank you.
- They're pulling up. - Okay.
Thank you.
Agent Dunham. We appreciate your help on this.
Hello, Agent Lee.
I button my jacket.
So where do you want me?
We've got audio surveillance in that vehicle. We'll monitor from there.
Okay, that's fine.
Showtime.
I'm not afraid. I'm not afraid.
Ready to do this?
Gotta gas it.
Yeah, yeah.
- Can I do the windows? - I would love it if you would.
Well done, my girl.
That is beautiful work.
Want a snack?
Walter.
Walter!
Do you have any idea how loud that was?
- A man may soothe his soul. - You found that soothing?
Do you have any idea what it cost Mozart to create that movement?
Stop.
What's wrong with you?
Nothing.
My nerves are a bit raw.
I haven't been sleeping well.
I checked your meds and the counts are way off.
- You've been overdoing it. - I've been experimenting again.
It's okay.
I'm gonna help you get back on track.
But if there is something else going on, you need to tell me.
I need to rest, that's all.
Perhaps I'll go lie down.
He needs to feel in control.
Messy spaces bother him.
He's highly intelligent.
He's probably self-taught.
He's fascinated by the brain.
"Germany. China. Uh, Thailand."
Yeah, he ordered a lot of parts online...
from overseas for the schematics that he designed.
What are these for?
We don't know.
He needs to divert himself from his misery...
so he builds things to occupy his time.
You hate being out here, don't you?
Why do you say that?
Because it would drive her crazy.
I'm fine with it.
Egg-hatching lights.
My dad used to work on a farm.
We had chickens for a while.
I don't know what he'd be using this for.
Does anything else stand out to you?
Mm. Uh...
Uh, he's deeply unhappy.
He grew up feeling deprived.
Other kids had things and he didn't.
He's trying to make up for it now...
but he can't.
Dinner's important to him.
He hunts during the day.
He blends into his surroundings.
I have to go to the bathroom.
- Okay. Come straight back. All right? - I will.
Don't touch anything you don't have to.
- I'll just finish your job for you here. - Okay.
There's one across the street.
- What? - The chair.
Uh, we had a set of chairs like that in the house that I grew up in.
That's crazy.
It's exactly the same.
- I loved that chair. Ha, ha. - Well...
Huh.
- Oh, my. - What do you think?
There's too many of them.
They're strangers to him.
Uh, he doesn't know them.
Why have them displayed?
Because he's jealous of them.
Because he...
He hates that they have happy lives.
That's what he looks for.
He takes them when they're happy.
His feelings are all that matter. He wants to feel better.
Mom?
How can he have this?
Do you know that man?
He's my father.
What is this? What...? Is this some kind of a joke?
No, John, this is not a joke. Of course not.
What the hell is going on here? Why do you have a picture of my father?
And the same chair from my childhood?
- It's over. - Don't.
He's my responsibility.
- Professor. Professor, wait. - I'm finished here.
Where am I?
- I should have removed the pictures. - You took a calculated risk.
I thought it would work too.
Broyles didn't want me to do it, and Charlie thinks I'm insane.
Charlie is on a beach with the bug lady.
- I'm sorry. Mrs. Bug-Lady. - Okay.
Besides, it's not over yet.
- I'm gonna go in there. - Give her a minute.
Don't.
In this universe, some things are the same and some things aren't.
People make different choices...
and therefore end up in different places.
This is...
like a nightmare.
John, anything that you can tell us about him?
Anything will help.
I don't just understand him...
I am him.
What's in him is in me.
What do you mean?
You're not the only one with secrets.
Go on.
For as long as I can remember...
I knew something was wrong with me.
My father, he knew it too.
He saw the darkness.
He used...
a heavy hand to try and fix me.
The brutality of it, it was...
I also came from an abusive home.
My stepfather.
It's no mistake that I do what I do.
I want to understand myself.
I want to help people like me.
Have you ever acted on it?
No.
But I've wanted to.
What stopped you?
Not what, who.
She...
She helped me find just small moments of peace.
Moments that I can hold on to.
- Your mother? - No.
My mother would...
Her name was Margery.
And what my father did with cruelty, she did with love.
She taught me that I didn't have to live in the darkness.
That when I got the urges...
I could just step out of it, into the light.
This... This is crazy, this... This is...
Because sometimes when I imagine...
what my life would've been like without her...
this is it.
Can I see you?
I wish I could tell him.
Tell him what?
That it doesn't have to be this way. That there's a way.
He just had no one to teach him.
I mean, you said so yourself.
Some things happened some way in this world...
and some didn't, right?
That may be so.
But, John...
he can never know that you exist.
You understand that?
- There's no other road for him. - Right.
Her name is Noreen Miller, 32.
Okay. So when did this happen?
She disappeared from a gas-station rest stop about an hour ago.
The security cameras picked up an image of him before she disappeared.
There's another victim?
John thinks he may be able to help you find him.
Let's go get him.
- Where is he? - Bathroom.
It's gone.
- What's gone? - Photograph of his father.
I take full responsibility. I'm the senior officer.
- Lincoln's just trying to protect me. - I'm not interested in culpability now.
- Do we have any leads? - We think we know where he's going.
You don't sound entirely convinced.
We think that he's trying to find the killer.
And why would he do that?
Because we believe he wants to stop him.
We're online.
Professor John McClennan is not from here.
The differences between his universe and ours will take him time...
to comprehend, making it easier to track him. He doesn't have a show-me...
which means his access to public transportation is restricted.
There's a 43.2 percent chance that, under extraordinary circumstances...
he'd be willing to steal someone's identification.
I'd say this is pretty extraordinary.
Initial calculations indicate that there are 219 potential routes...
he could have taken in the time he's been missing.
But the possibilities branch out exponentially the longer he's out there.
Even with our facial-recognition programs...
going through that much data is going to take time.
How long?
Thirteen hours, plus or minus.
If you're right, Agent Dunham, then finding Professor McClennan...
is our best chance to save Noreen Miller.
- Let me know when you have something. - Yes, sir.
I have an idea.
That woman processes more information in an hour than we will in a lifetime.
So if she hasn't thought of it, it's not there.
She didn't see the photograph of John's father, and I did.
John said his father worked as a farm hand.
- If we can trace the farm... - But we can't.
Johns' father didn't own the farm. His name wouldn't be on it.
In the photograph, he was standing in front of a tractor with commercial plates.
Pennsylvania TR53H79.
We can trace the registration.
Weir Farm.
Shut down 10 years ago after the Richboro fires.
It's been unoccupied ever since.
Noreen Miller.
Goes without saying, but I'm still gonna say it:
All necessary steps should be taken to bring her home unharmed.
Any questions?
Let's go.
Ride with me.
It doesn't have to be like this.
You don't have to hurt her.
You're going for the.45, silver. You keep it in the toolbox.
How did you know that?
That's where he kept it.
My dad.
What are you?
I was like you.
And then one night in October, I went to a fair.
I was 10.
And that's the night that my father found the dead things.
Only I didn't know that yet. I was playing carnival games.
And I saw him coming toward me. And I knew that he knew.
- The moment I saw him, I knew... - That's my life.
That's what happened to me.
It was the ring toss that I was playing.
Yeah.
Me too.
- I hid. - Behind the wagon wheel.
But he found me.
Grabbed me by the collar, his fingernails cut into my neck.
He dragged me home and beat me for three days straight.
Not me. I ran.
As far, as fast, as long as I could.
I woke up in a field.
And this woman was standing over me.
Her name was Margery.
And because of her...
I don't have to do what you do to stop the pain.
- You can't control it if you're like me. - I can control it.
- She taught me how. No. - This is the only way.
- I do this, and for a while it's quiet. - I can stop the urges. No.
I know the screams inside your head that won't stop.
It's a horrible place to be. But I can help you.
Like Margery helped me.
You can step out of the darkness.
Don't you want the pain to end?
- Yes. - I can show you how.
Maybe you can.
What you said to John...
about your stepfather, you were trying to open him up.
Yes.
It's also true.
- So, what happened to him? - My stepfather?
I killed him.
We are ready to begin.
Tell me about your happiest memories.
Tell me about Margery.
Inside.
Downstairs.
It's clear.
- Damn it. - We're in the wrong place.
You all go down to the sheds.
We're not quite clear. Hold on.
What are you thinking?
Over there.
There was a structure here.
It could be anything. A shed, a barn.
There's another one.
There was a group of structures here.
This is where the family lived.
How did Margery make you feel?
Safe.
She was so kind.
So gentle.
I never understood how someone so beautiful...
could love something so dark.
Don't have to do it anymore.
She's sedated...
but her pulse is strong.
Put your hands where I can see them.
I wanted what he had, what she gave him.
- John, put your hands up. - I took her from him.
I shouldn't have.
She made him feel for them.
What have I done to all of them?
Margery, what have I done?
How's the professor?
There appears to be no permanent damage to his motor functions...
or cognitive ability.
He is, however, suffering from partial memory loss.
Partial?
He's unable to recall the events of the last few weeks.
He has no memory of ever being involved in this case.
What about Margery?
His memories of Margery were extracted.
The neurologists believe the loss is permanent.
For all we know, she's the only thing preventing him...
I know.
Once he's released, we'll have to keep an eye on him.
Can I talk to him?
He's been told he was injured doing profiling work for the FBI.
Okay.
Hi.
Do you remember me?
Nothing at all?
I'm Olivia Dunham. I'm one of the FBI agents who was working on the case.
They tell me I saved a woman's life.
Yes.
And probably many more.
I came to say thank you.
I was glad I could be of help.
Do you remember Margery?
The other agent asked that too.
No.
But things are pretty dark right now.
Did she have something to do with the investigation?
Sort of.
Feel better soon.
You know what they say:
That even when it's the darkest, you can step into the light.
He knows what she taught him, but he can't remember who she is.
How is that possible?
At the risk of sounding sentimental?
I've always thought there are people who leave an indelible mark on your soul.
An imprint that can never be erased.
Walter. I'm here.
Who are you?
Can you hear me? I'm right here.
No.
Walter, I'm right here.
No, you're not.
I'm here, Walter.
You... You're just a figment of...
Walter, I'm right here.
I'm right here, Walter. I'm right here.
Walter, I'm here. Can you hear me? I'm right here. Walter.
Help me, Walter.
Please, help me.
