Fringe

Hello?

Hey, honey, I'm glad I caught you.

Where are you? Did you make it?

Airport lounge.

About to board in 15 minutes.

Look, Nat, I know with Mom being sick

and me traveling so much I feel bad.

I told you it wasn't gonna be like this anymore.

It's all right.

We'll just do something next weekend when you get back.

You're not upset?

No, I understand, don't worry.

I mean, if you have to work, you have to work.

Are you on your way home?

There was some traffic,

but I'll be home in about five minutes.

Hey, listen, they just called my flight.

Okay. Have a safe trip. Call me when you land.

I will. Happy anniversary.

I love you.

I love you too.

Randy, you're gonna get it.

Randy, you totally got me.

I had no idea.

Randy, stop it. You're scaring me.

Randy?

Randy?

No... no... no...

"Earthling"

BROYLES.

This doesn't make any sense.

There's no forced entry, no signs of a struggle.

Walter, do you have any thoughts?

Reminds me of Christmas.

Like a fire log that burns so hot it remains intact,

holding the shape of its former self.

You used to love that when you were a child.

You'd poke the log with your little finger

when it had cooled,

and you'd draw genitalia on the reindeer decorations.

Happy memories, Walter.

But I think what she meant was do you have any thoughts

as to what happened to Dusty here?

Well-well, the seat cushions have no scorch marks,

which rules out any form of fire

or spontaneous combustion.

So could he have been dosed by something?

Yes, it's possible.

But before we can determine cause,

we need to find some way to transport

Mr. Dancik's remains back to my lab.

So, um...

Well, Peter, I'll need a dust devil.

A vacuum cleaner?

Yes, you're right.

Well, we'll need several.

What do we know?

Randy Dancik.

His wife found him.

She thought he was on a plane to Hong Kong.

But he stayed home to surprise her

for their anniversary.

Did this man happen to be a doctor or work in a hospital?

No, he was an investment banker.

Has he visited a hospital in the last 24 hours?

I can find out. Why?

It's not the first time I've seen this phenomenon.

Four years ago in D.C.,

several victims were turned to dust like Mr. Dancik.

By the time the killings ended, there were five deaths.

Each of the victims worked at or had recently visited

Tyson General down in D.C.

After the third death,

I was contacted by an Eastern European man.

He knew case-specific details.

Details that only the killer would have known.

He offered to turn himself in,

but only if we could decipher his formula.

What formula?

It's a molecular model.

Some kind of complex organic compound.

I recognize a couple of these elements,

but the others I'm not so sure.

What is it?

Don't know, but he implied that solving it

was the key to stopping the murders.

C.D.C. and N.I.H. chemists worked around the clock

but couldn't break it.

There were two more victims, and after that, he stopped

and the trail went cold.

Until last night.

I'm gonna get these to Walter right away.

Dunham.

Thank you.

PD confirmed with Dancik's wife

that he visited his mother in a hospital yesterday morning.

Which hospital?

Uh, Latchmere General.

The Latchmere Health Alliance is actually made up of

three separate hospital campuses

and a network of diff-

This is the hospital we're interested in.

We need to review all your employee records.

We're looking for an employee here

of Eastern European descent who may have also worked

in a D.C.-area hospital about four years ago.

We're looking for a match.

This is a warrant giving us access to your network servers.

My agents will need to take over this office.

Excuse me, miss.

Walter, that is a man's remains you're playing with.

Indeed. Reduced to its most elemental components.

Carbon and calcium.

One Geiger counter. Batteries replaced.

- Thank you, my dear. - Mm-hmm.

You think some sort of radiation passed through him?

We all carry low amounts of radiation.

The water we drink, the food we eat.

Seven rads or so.

But that equation describes something organic

and highly radioactive.

If it has anything to do with the man's death,

then this man will be in the mid to low hundreds.

This doesn't make any sense.

Even reduced to this state, Mr. Dancik should have

some trace amounts of radiation.

Maybe it dissipated when he did.

- It's unlikely. - Hello?

Yup, he's right here. Hang on.

- Thank you. Hello. - Mm-hmm.

Hey. Has Walter made any headway on the body?

Just that it doesn't contain any radiation.

Otherwise it's just a pile of dust.

What about the formula?

He hasn't cracked it yet,

but he thinks it may describe some kind of organism.

And as of a couple hours ago,

he started referring to it as a "she. "

Oh...

Hold on a second. Here he is.

Agent Dunham.

The formula is a different matter entirely.

She's a complex chemical puzzle.

What, I don't know.

But can you solve it?

W-Well, first I would need to break her

into her organic and inorganic parts.

And then...

Walter?

Hello?

Titanium tetrachloride.

You sly temptress.

Walter?

Hey. Me again.

Needless to say, he's into it.

I'll keep you posted.

Okay. Thanks.

What do we have?

We're indexing the employment records for both hospitals

against any Eastern European names.

Nothing yet.

You know, I can stay.

You should go home.

I'll wait.

Why'd the killer call you?

Was it just to taunt you?

Quite the opposite.

He was distraught.

Said he couldn't control it.

I got the overwhelming impression

that however he was killing these people,

he wanted it to end.

Until today, I thought maybe it had.

Something's going on.

Did you see anything?

- I want this floor sealed. - Yes, sir.

Agent BROYLES, we have a name.

Tomas Koslov.

He worked at the hospital in D.C.

and quit the week the murders stopped.

How long till he started working here?

About a month later.

He's a night nurse in the coma unit.

He never showed up for his shift tonight.

FBI. Tomas Koslov?

Clear.

Clear.

He knew we were coming.

He must have seen us at the hospital.

what do you think it is?

Soldering iron burns, electronic components.

He was building something.

I understand. Thank you for running it.

Tomas Koslov was an alias.

Nothing on that name in any of our databases.

He forged his medical records and previous employment.

Well, we still know he's Russian.

Cyrillic letters?

Tomas, whoever he is, certainly didn't get that

from anywhere around here.
