Previously on Fringe:
- The First People. - You're holding one of last copies.
What are we talking about? Adam and Eve?
No, before dinosaurs. They were the first people.
They were a people of great technological prowess who made...
the ultimate discovery.
Walternate said that it was a very powerful piece of ancient tech.
- This machine is dangerous. - We need to understand it.
When I touched that device on the other side...
it came alive in my hands.
How can you expect me to ignore that?
Walter didn't have brain tissue implanted. He had it removed.
- What are you doing, Walter? - I'm making myself smarter.
If I can think like Walternate, I can figure...
what he's trying to do with that device.
The picture of me in the device.
What does it mean?
What's going to happen to me?
Clearance and ID.
You have any chewing gum?
- Excuse me? - I'm sorry.
He's got this thing with his ears.
It's not a thing with my ears. I've got a blocked Eustachian tube.
And it's a perfectly natural reaction.
Any flavor will do, although I'm rather partial to grape.
Welcome back, Colonel Broyles.
We've tried a dozen different power sources.
- And there were no reactions? - We've run all the diagnostics.
The machine continues to be unresponsive.
Miss Sharp, your guests are here.
Expand the telemetry parameters and run the tests again.
You broke the encryption on the computer the other Olivia left behind.
A few days ago. Peter gave us a number of password suggestions.
- One worked. - Oh?
Yeah. It was a song lyric.
And Fauxlivia ruined U2 for all of us.
- Fauxlivia? - That's what Walter's calling her now.
- Fauxlivia as in Fake Olivia. - Ah. Uh...
The data on the computer. What did you find?
Unfortunately, it's one big file. Mission details buried in hundreds of pages...
of mundane observations about our world.
Don't know what's valuable, what isn't.
- And we can't identify any type of code. - Oh, my.
It's bigger than I imagined.
Well, I suppose...
it's just big enough to destroy a couple universes.
So far we haven't been able to figure out how the machine works.
NASA, The CIA, The NIH.
We've had government's top people at our disposal.
- Which are you? - Excuse me?
Which agency do you work for?
Walter, this is Dr. James Falcon, our lead scientist on this project.
Well, I suppose that makes me your boss.
I'm Dr. Walter Bishop.
Sorry for the interruption. Please continue.
As I was saying, we're confounded.
Doesn't seem to be an energy source...
and nothing that suggests the machine can hold or transmit any type of power.
Jack, are you getting this?
Yeah.
Some kind of electromagnetic spike.
The problem must be the missing piece.
The one that the other Olivia stole.
That could be right.
The piece was from the center. It could be the power source.
Did the other Olivia mention the machine in her files?
We're still working through the data.
God.
It's like something triggered it.
Something did trigger it.
Me.
Peter, you've been out?
No, I just came downstairs.
I couldn't sleep.
I thought I heard the door.
You must've been dreaming.
I don't think so. I wasn't sleeping either.
- Is that peanut butter? Can I have one? - Mm-hm.
How you feeling? Any more nosebleed?
- No. - Headaches?
- No. - But you're unable to sleep?
Yes, but I don't think that has anything to do with the machine, Walter.
Might.
We don't know yet. We don't know anything.
The first people's book.
I read it cover to cover a dozen times.
There's nothing to suggest how that device works...
or how it's connected to you. - Walter, stop, please.
I want answers too.
I know you wanna help me, but I don't think that you can this time.
You can't protect me from everything.
Only a couple more, Mr. Bishop.
You haven't convinced me that this is necessary.
Every human being gives off a unique electromagnetic signature.
We're testing if your son's triggered the machine.
I have a graduate degree from MIT as well.
I don't need a test to know how unlikely it is...
this has anything to do with electromagnetics.
- Walter. - Peter.
Do you have any idea how much radiation you're about to be exposed to?
Well, I do now, Walter.
- Walter, I think you're overreacting. - May I have a word in private?
We can't fire him.
He's one of the most gifted biomedical engineers in the country.
I don't care who he is. I don't want him poking and prodding my son.
- I know you're worried about... - I'm not worried, Nina, I'm terrified.
Did you see the way that machine reacted to him?
That is why we're running these tests.
This is a waste of time. It's not going to tell us anything.
Nina, I need you to do something for me.
I've been trying to regenerate my brain cells.
But William was too clever for that.
He not only took out pieces of my brain...
he inhibited their ability to replicate.
- Walter... - But Belly kept detailed notes...
of everything he did.
I want to see his research to know how to reverse what he did to me.
To re-grow my brain cells.
Walter, that's more than 15 years ago.
I'm not whole, Nina.
If I'm to figure out how Peter is connected to the machine...
I have to get smarter.
It's the only way I'll be able to help my son.
Yes. I'll get on it right away.
Thank you.
Hey.
- You okay? - Oh, yeah. Yeah, I'm great.
I think I might use my newfound superpowers...
to make this machine levitate.
Well, now that would be impressive.
I tried to call you last night and you didn't pick up.
Ugh. Yeah. Walter was being Walter. I had to go for a walk.
We're ready. Do you want something to help sleep?
- This might take a while. - No. I'm okay. Thanks.
Peter, relax. This procedure's perfectly safe.
Heh, I'm sorry, doc. You'll forgive me if I'm leery of machines right about now.
I understand.
Okay, well, I'm gonna be right outside.
I see Dr. Bishop leaves the high intensity work for you.
Agent Broyles. You know they're all over at Massive Dynamic.
I know. I came to speak with you.
For the past two days, an encryption team has been waiting...
for the data on other Olivia's drive. - Yeah. I hear it's one big mess.
More than 300 pages of material.
Details about this world. Profiles on our people. Mission specifics.
It's difficult to know what's important.
Well, I'm happy to help.
I knew you would be. And we certainly could use your skills.
But there's a reason I haven't already asked.
Her mission logs are filled with personal observations.
Many of them concern her relationship with Peter.
Peter and Olivia have been through...
I understand.
I'll be discreet.
The file is on the mainframe.
Broyles.
I'll be right there.
Yes. I admit his rate is a bit high.
Hundred and thirty beats per minute is hardly a bit high.
I want you to take him out of that machine right now.
It's a very narrow tachycardia. It's hardly life-threatening.
It would be ridiculous to stop testing for this.
- So, what is going on? - Peter's heart rate is a bit elevated.
I assumed it was nerves at first, but he should've stabilized by now.
His heart rate could've triggered the machine?
No, I don't see how it could have. But it is curious...
and implies we should do more tests.
By all means.
Let's use my son as the new Massive Dynamic lab rat.
I don't think the doctor was...
Dunham.
I'm on my way.
Okay. I've gotta go. Can you call me if you learn something new?
His name was Michael Baird.
Found in the fountain by a colleague.
ME thinks he was murdered sometime around 3 a.m.
So, what's with the dead fish?
- They died of mercury poisoning. - Mercury?
He's a shapeshifter.
That's not all.
Turn him over, please.
His data storage disk was removed.
Thank you. Whoever did this knew what they were doing.
So why would someone kill a shapeshifter?
You mean someone other than us?
Okay. What if this was Walternate?
What if he sent over some type of cleaner to tie up all the loose ends?
- To kill this guy before... - Before we learned what he knew.
What are you thinking?
This is Astrid.
Agent Farnsworth, I need you to run a search on the other Olivia's data file.
- Okay. What's the name? - Michael Baird.
Yeah, he's on a long list of port authority employees.
Shut down the mainframe. Shut it down now.
And from this moment on, no one accesses that file except you.
What's going on?
We cracked the encryption on the other Olivia's hard drive 36 hours ago.
Among the info, she lists thousands of names. Michael Baird is one of them.
Suppose Walternate knew...
we were getting close to identifying the list of shapeshifters.
How would he know that?
Because someone on our side may have told him.
We got a mole.
Well?
I'd cut back on fried foods.
But your lab work, the EEG readings, it all looks pretty standard.
Nothing to indicate you and the machine share a signature.
Nothing out of the ordinary?
Well, like I told your father, your heart rate was a bit elevated.
But that could be adrenaline, nerves, stress.
When I got within 50 feet of that machine...
things started flying. My nose started bleeding.
You're trying to tell me that that's just a coincidence?
No. I'm telling you we still have no idea how any of that happened...
but from a medical standpoint, you seem perfectly normal.
I'm willing to run more tests. But, frankly, I thought you'd be relieved.
Well, hey, you're the doctor.
Peter.
Agent Dunham called.
They found a dead shapeshifter.
She thinks someone on the inside must be feeding Walternate information.
Let's go.
- Thank you. - You're welcome.
The shapeshifter was killed because someone knew...
it was a matter of time before we ID'd him.
Round up anybody who had access to other Olivia's hard drive.
- We're already on it. - The FBI decryption teams.
- Anybody in Massive Dynamic. - Okay, Peter.
We're on top of it. We're questioning every one as we speak.
That's what Walter and Nina are doing now.
What about the rest of her file?
Does it mention other shapeshifters?
Newton's mentioned. If there are two of them, we're assuming there are more.
But there are 100s of names throughout the file.
Just lists of government employees, local cops.
We're running profiles on all of them.
Looking for anything that might indicate a change in behavior.
Which would suggest having been replaced by a shapeshifter.
Well, it looks like a big job. So how can we help you sift through the data?
Um, it's not a good idea.
Why not?
Because she wrote about me.
Yeah.
Some parts of this read like a diary.
You're quite prominent.
We should get to Massive Dynamic.
Okay, call me if you find something.
State your full name, please.
Special agent Matthew Nicholas Goldin.
The name Michael Baird mean anything to you?
No, it does not.
- Where were you born? - Brooklyn, New York.
How many more are there?
Twenty-two of our people. Another seven from the FBI.
So far, all the blood tests have come back negative.
But that doesn't rule out the possibility of a human mole.
Lie detectors are unreliable.
He's right. People beat them all the time.
But not this one. William designed it.
It measures the slightest shift in facial muscles...
which allows us a link to stress and a particular emotion.
His facial muscles tell us that his stress is not connected...
to feelings of guilt or shame.
Very clever. I wish I'd thought of it.
We need to keep everybody in custody until we find the leak.
There are nearly 30 people on the list. I'm not sure that's practical.
Do you actually wanna catch this mole?
Do you know the identity of any shapeshifter?
No, I don't.
You know anything about the murder...
- Walter, do you have a moment? - Yes. Yes, of course.
Have you given any information...
to assist in the murder of a shapeshifter?
No, I haven't.
You were right.
I found William's research.
His notes suggest that he designed a retroviral serum...
based on your DNA...
that will re-grow your brain tissue.
That's wonderful.
Oh, thank you, Belly.
Walter, William experimented with lab animals first.
A rat and a chimpanzee.
Now, back in the '90s, we had a small lab fire.
The original labels were destroyed.
I'm gonna ask the lab to run diagnostics on all.
Then they should be able to tell us which one was made for you.
Walter.
Don't worry. I've snorted worse.
A few good whiffs...
and my brain should be able to begin to re-grow its missing parts.
And what if the serum is not based on your DNA?
Well, I'll probably get a rash.
Well, I'm afraid we've got a bigger problem on our hands.
- I'm worried about Peter. - So am I.
- But that's what this is all about. - Peter has endured a lot recently.
- Maybe he should talk with someone. - Heh.
No, what I'm trying to say is there are people that are trained to help.
Nina, he's my son.
I'm the one that needs to help him.
Do you know anything about the murder of Michael Baird?
No.
- How long have you been FBI? - About five years.
Peter.
And you never heard of Michael Baird before?
About the other Olivia's files.
I know you slept with her and I know that you're trying to protect me.
But reading about it isn't gonna make it worse.
I'm not doing any good here.
But if I could help Astrid with the files...
Olivia.
I've conned people.
And I know what I would've written about them.
She must've thought that I was a fool.
And I don't want you to see me like that.
All right, we're done.
That's it. We've talked to everybody.
We should call Broyles and tell him.
What about Dr. Falcon?
Falcon wasn't on the team that worked on the drive.
He was asking questions about it yesterday at the hangar.
Hey, it's me.
Uh, could you send Dr. Falcon up, please?
Why not?
What?
Dr. Falcon left work early.
Clear.
Bedroom clear.
Hallway clear.
The same as Michael Baird.
Two shots in the head and his data storage unit had been removed.
You're right. Dr. James Falcon. He's on here.
He's part of a list of Massive Dynamic employees.
Dr. Falcon's name is on her computer.
So if Waternate's knocking these guys off...
they must know something.
Damn.
Yeah. Tell Walter I feel the same.
That's not about the shapeshifters. Walter's giving himself an IQ test.
Okay. Falcon's body is being taken to the lab.
So when Walter finishes exercising his mind, can you get him to take a look?
Maybe he can find something that'll help identify killer.
Of course.
Astrid's still going through her files.
But so far no luck identifying the remaining shapeshifters.
Don't think we're gonna find anything to tell us who Falcon was working with.
It feels like every time we learn something new, we're still a step behind.
If we could get to one of the shapeshifters maybe we could get answers.
My bone saw, dear.
The aspirator, voltmeter and a ripe banana.
Please tell me the banana's for you.
I had a sudden craving.
It's odd though.
Bananas are typically my least favorite fruit.
Oh, news.
Yeah, but it's not good.
Another 20 names have been cross-checked from Fauxlivia's files.
None of them are shapeshifters.
So you've read all Fauxlivia's files?
Yeah. Most of them.
What did she have to say about me?
She liked you.
She thought that you were kind and brilliant.
Would you help me with him, please, dear?
Walter.
Oh, I'm sorry. That was very rude.
- I was displaying dominance. - Excuse me?
The serum I took. It must've been meant for a chimpanzee.
You mean its growing chimp DNA in your brain?
Well, just a bit.
It's fascinating though, isn't it?
How the tiniest change in our composition...
can yield such drastic changes in our behavior.
It's not surprising, really.
After all, we share 50 percent of our DNA with a banana.
You sure it isn't dangerous?
No.
It'll pass.
My immune system will recognize it as foreign and reject it.
Mm. So...
the bone saw, please. Mm.
- What is it? - I'm not sure. Magnify.
Looks like blood.
So this must've been how he got in.
It looks like he used a knife to jimmy open the window.
Which would suggest that he and Dr. Falcon...
were strangers or otherwise...
he would've used the front door, right? - Hmm.
Peter.
I owe you an apology.
For what?
The last few weeks have been really hard for me.
I've been focused on what other Olivia did to me...
that I just haven't thought about what she did to you.
- Look, Olivia... - And...
I want you to know that I'm sorry and that I get it now.
That good news is that she's gone.
I know it doesn't feel like that at the moment, but she is gone.
And, um...
we can get past it.
Thank you.
I gotta do more tests at Massive Dynamic.
- Want me to drive? - I'll take the train.
Could you call Walter, let him know I'll be home late...
and not to worry? - Mm-hm.
Thank you.
- Dunham. - It's me.
We just found blood under Dr. Falcon's fingernails.
So the killer is human?
Appears so.
Type A positive. It's fairly common.
I'm A positive along with a third of the population.
I'm searching personnel files now...
and there is only one person with that blood type...
who had access to Fauxlivia's files.
Brandon Fayette. Nina sharp's chief scientist.
Spare some change, lady?
Yeah. Sure.
Don't move.
Can I swallow?
Hey, Bermudez.
Have you ever killed a shapeshifter?
No. I've been going to the gym though.
I'm stoked you'd think I'd have that kind of strength.
You can keep asking questions. Machine isn't gonna give you a different answer.
- I didn't do it. - He's right.
Machine says he's telling the truth.
Hi.
What have you got?
It's not Brandon.
We questioned him and he passed the polygraph.
That's not unheard of. Lots of people defy a polygraph.
Not this one. Which one of these haven't you gone through?
I understand why nobody wants me to read these files.
But what's written here is in the past and what is important is the future.
Somewhere in here are the names of remaining shapeshifters.
And we're running out of options.
Yes. We have to find them before whoever's killing them does.
Believe me. Broyles is calling me every 20 minute to tell me the same thing.
It's not the shapeshifters I'm worried about.
If we can find next target, surveil him, maybe we can catch this guy.
I am really thankful for your help. Seriously.
But I've been through this whole stack already.
But I'm not just another set of eyes.
We're the same.
The other Olivia and me. I should be able to think the same way.
So maybe I'm gonna be able to find a pattern.
Hello?
- Walter, it's Nina. - Nina.
I was just thinking about you. Heh.
Oh!
The first sample is definitely chimpanzee.
- You can label it now. - First sample?
Belly's serum. I'm ready for round two.
Actually, I was calling for Peter.
He's not with you? Has he finished the tests already?
Finished? No, no, that's why I'm calling.
I wanted to schedule a round of tests.
But Olivia said...
I must've misunderstood.
Walter, I understand how you feel about this testing.
And I know that Peter is reticent as well.
But I also know that you understand why these tests are so important.
Will you tell him I called?
Yes.
I'll give him the message.
You okay?
"It's strange, but at moments when I'm with PB...
I find myself forgetting what I'm here for.
PB's different than I expected him to be.
A sincerity behind his eyes...
a deep-seated goodness.
It's hard not to get caught up in it...
not to get caught up in him."
This may have started out as a mission, but it turned into something else.
She was starting to have real feelings for him.
- Olivia... - No, I mean, he's a great guy.
And, of course, we're the same. She would see what I see.
We speak the same. We use the same phrases.
I'm reading this and I'm thinking, this is how I make sense of things.
Make sense of feelings. Of Peter.
We even use this...
Olivia?
Okay. I think I got something.
You need the original printout of the file.
Exactly what am I looking for?
When I was little my mother called me Olive. Hers did too.
I think this is a letter substitution code.
So O-L-l-V-E.
O is the 15th letter of the alphabet.
So on the 15th page, the 15th name is...
It's Newton.
L is the 12th letter of the alphabet.
12th name on the 12th page.
Michael Baird.
And I is the ninth letter of alphabet. The ninth name on the ninth page.
James Falcon.
The 22nd name on the 22nd page is Jackie Bermudez.
And the last one is Zach Alpert.
Okay, we got them.
Unh!
- Ugh. - Hello, my friend.
I was expecting you.
Where are you getting your information?
How did you find me?
I know who you are, Peter.
You might think...
that we're not allowed to kill you.
But that doesn't mean that we can't hurt you.
We can get everything we need from you...
even if you only have nine fingers or...
one eye.
Peter.
Broyles.
Jackie Bermudez's apartment was empty.
We got a team sitting on it in case she comes back.
Damn it.
- You okay? - Yeah.
So five shapeshifters.
- How'd you break the code? - Five letters in Olive.
Yeah, and Newton, Baird, Falcon are dead.
Bermudez is missing.
So that leaves one.
How'd you find me, Walter?
I found your notes. Fauxlivia's file.
They were right on your desk.
I'm smart enough to open a phone book.
I looked the man up.
You killed them all, didn't you, Peter?
And it's been useless.
I didn't learn anything from the rest of the data disks.
But he's the last one. He must know something.
Peter.
I have to know what they know, Walter.
I'm tired of being reactive.
Son, this isn't you.
- You can't just... - They're soldiers, Walter.
They're here to kill us.
Besides, they're not even human.
And I'm not doing anything wrong.
Then why didn't you tell us?
If you weren't doing anything wrong, why didn't you tell us?
I don't know what's happened...
but this is not you.
- Hello. - Peter, it's me.
Good news. We identified the last two shapeshifters.
We're heading to Zach Alpert's apartment. It's in Revere.
I'll let you know if we find him.
We failed. He got all of them and now he's gone.
We don't know who he was.
We're always just a step behind.
Well, we still have the other Olivia's computer.
Maybe Astrid can learn something.
Okay. I should get home.
- Bye, Walter. - Bye.
Peter, I read her file.
You should know that you have nothing to be embarrassed about.
Thank you.
I think I know what's happening to you.
Every relationship is reciprocal, Peter.
When you touch something, it touches you.
You're changing, son.
When you touched the machine, it changed you.
It weaponized you.
So, what do we do now, Walter?
I don't know.
I understand you have news on the device.
Not exactly, but we found these three copies of the first people's book.
Where did we find them?
One was in a museum. The others, private collections.
The owners did not wanna part with them.
But it kind of helps when you have unlimited funds.
And they all say the same thing?
It's in three different languages written by three different authors.
They're all published within two years of each other.
So forgiving for the translations, they're almost literally word for word.
And what do you make of it?
A civilization that existed millions of years before the dinosaurs?
The planet has been spinning for five billion years.
We've only been around for the past 250,000.
There were six major extinction events before we even crawled out of the slime.
So who's to say that one of them didn't wipe out a great civilization?
Hmm.
There's another thing.
When we put the word out we were looking for copies of the book...
we found out we weren't the only ones.
A few years ago, somebody started a similar search.
- Who? - William Bell.
