Fringe

Previously, on Fringe...

We have evidence that indicates

William Bell may be involved

with several biological attacks.

I will turn this world over looking for him.

William Bell is not in this world.

I've been waiting for this.

Who are you?

- I'm William Bell. - Where am I?

You were missing from your car for at least an hour

before you came crashing back through the windshield.

He told me something.

Who?

I don't know, I can't remember.

But it was very important.

There's something that I have to do.

Walter thinks...

he was a shape-changing soldier from another universe.

Charlie, what if I don't want to remember?

Mind if we speed things up, Kurt?

I'd hate for these popsicles to melt.

I don't think we have to worry about that.

Cargo is secure.

Who is this guy?

Hey, I was wondering if I could get some directions.

What are you doing here? You're trespassing, pal.

Why don't you get in your car and turn around?

Yeah, sure.

Oh, my God! Son of a bitch!

We got to call--

- Anyone else in the warehouse? - That's it.

The keys are in his pocket.

Let me know if he's in there.

You know where to reach--

Aah!

"Momentum Deferred"

100, Walter.

Almost.

50 more chops.

- Agent Dunham. - Walter, hey.

So, you said you wanted to see me.

Oh, I had an idea.

I think I may be able to help you retrieve

your memories

from the accident, when you disappeared

from the automobile in New York.

I-I remember that bit.

Of course you do.

Walter, I thought that we agreed that this was a stupid idea.

No, you decided.

I still maintain

that the principle is perfectly sound.

He wants you to eat worms.

Not just worms, flatworms!

The thing is, Agent Dunham,

I recalled an experiment that Belly and I did

w-where we trained a handful of flatworms

to respond to light.

We then crushed them up and fed them to other worms.

It was Belly's idea.

Because who wouldn't think to do that?

The point is

that these other worms, without having been trained,

began to respond to light.

It seems the first worms transferred their memories

to the other worms through ingestion.

Right, but that still has nothing to do

with stimulating Agent Dunham's memory.

How will we know unless we try?

That's why it's called an experiment, Peter.

Thanks. I know what an experiment is.

- Uh, guys? - If Archimedes never decided

to take a bath--

Astrid, water.

I was going to mix it with strawberries.

Bishop's deli.

This is what we know so far.

Facility manager arrived to work this morning at 6:30,

saw the bodies and called it in to the local P.D.

So the robbery took place in the middle of the night.

That makes three cryogenic facilities in a week,

same M.O. as Chicago and New York.

Yeah, but chicago was a straight "B" and "E."

But in all three cases, the target was the same.

Frozen heads.

Which does bring up several obvious questions--

First of which, what the hell for?

Police recovered ten shell casings

from a nine millimeter.

Looks like a single perp rolled up and dropped four men,

two of whom were armed.

Excuse me.

Can I see the body that's bleeding silver now?

Fascinating.

Walter.

Perfect, son.

It has the consistency of mercury.

These robberies are obviously connected.

We should pull the files on New York and Chicago.

I'll make some calls, tell the local agents

that we're taking over the investigations.

Yes, sir.

You okay?

Uh, yeah. So, um, what does Walter think?

Meet Mr. Silver-Blood.

Walter thinks it's actually mercury.

Mercury?

Agent Francis, hello.

Hey.

You all right? You look pale.

Yeah. I didn't get much sleep last night.

Oh. I may be able to help you with that.

A little cannabis before bedtime does wonders, huh?

I recognize this.

This is the device the shape-shifter used.

You look like hell.

That was, uh...

That was sloppy.

You killed four men last night,

including one of our own.

There's nothing to link him to us.

Maybe not, but now the FBI--

They have him.

They understand what he is.

You've been in this body too long.

You're dying.

You need to get back home

and get fitted with a new conversion device.

I'd let you use mine...

but what would be the point?

Yeah.

It wouldn't do anything anyway.

You've asked for extraction.

They say not until the mission is done.

They're real sweethearts.

Damn. That's the last one.

He's not here.

There's another facility in North Carolina.

I have another idea.

Olivia Dunham is starting to remember her time

on the other side.

I'm thinking she may know where it's hidden.

His head?

Yeah.

What makes you think that?

If Bell knows that we're looking for it,

it seemed like a likely reason

why he'd bring her over to the other side.

Well, if you're right,

and you don't want that body to be your last,

then I suggest you do whatever it takes

to make her remember.

Why?

Why...

Why are shape-shifting soldiers

from another universe stealing frozen heads?

The most likely explanation that we can think of

is that they're looking for a specific head,

but they don't know where it is.

Okay. Then who?

We don't know.

These facilities pride themselves on secrecy.

So despite the thefts,

none of them have been willing to give up their client lists.

What about the other device,

the one we found a few weeks ago?

Did it give any indication who these people are?

Unfortunately, the other device is broken.

We asked Massive Dynamic to see what they could make of it,

but apparently they've been stumped.

Well, this one doesn't appear to be damaged.

So maybe Peter can figure something out.

I suppose he knows a guy?

He knew enough about engineering

to fake his way into M.I.T.

Well, let me know if you learn anything.

In the meantime,

I'm considering giving you a protective detail.

A protective detail? Why?

The last time Peter showed me one of these devices,

its owner had just tried to kill you.

I'm not worried,

'cause that was six weeks ago.

So if a shape-shifting assassin wanted me dead...

then I would be.

Let's see how this thing operates.

What are you saying,

this is not a person?

My dear, I'm not certain

that you're not simply a figment of my imagination.

No, this is certainly not human,

rather a highly advanced technology--

A mechano/organic hybrid.

I suspect that they produce or possibly ingest the mercury

and that it controls the tissue,

instructing it to take and maintain shapes.

What?

We have to call Agent Dunham.

I need to talk to her right away.

Okay.
