Original subtitles

Look, save your energy.

We'll have you out of there as soon as possible.

I hope.

Try rerouting the power coupling.

Mr. O'Brien.

See if you can activate the interlock servos.

Mr. O'Brien.

Captain Jaheel, those people have been stuck in that air lock

for over an hour.

Now, if you can wait till we get that door opened

I'll be happy to listen to any problems you might have.

But I've already been waiting two days

for your people to readjust

my ship's antimatter flow converter.

I'm afraid we've gotten a little behind

in our maintenance schedule.

I'm not interested in hearing excuses.

I have a shipment of Tamen Sahsheer

waiting to be delivered to Largo V

and I'll need to do better than warp 1

to get there before it spoils.

I'll try to get a repair crew to you by the end of the day.

Now, that's the best I can do.

Your best, Mr. O'Brien, hardly seems good enough.

Dax to O'Brien.

O'Brien here.

Can you spare a minute, Chief?

I have a little problem here at the lab.

On my way.

Thanks for coming, Chief.

What are you doing out here?

Have you checked the EPS converter?

Yes... first thing.

How about the intensity grid?

It's fine.

Then it's probably the secondary phase modulator.

We had trouble with them last week

in the main power core.

That should do it.

Anything else I can do for you?

The navigational computer

hasn't worked reliably for three days.

I ask for the star charts for the Argosian sector

Glessene sector comes up instead.

That's when I can coax this system on line.

Uh-huh.

Try it now.

Ah! That's more like it.

You look like you could use some sleep.

Who has time for sleep?

I'd settle for five minutes peace and quiet.

Chief, I thought you were going

to fix the replicators.

You're absolutely right, sir.

I knew I'd forgotten something.

Can't have the Operations Chief

sitting around daydreaming

when there's work to be done, can we?

Ho, ho, ho, ho. I'll get right on it.

"Fix the replicators, Chief."

"My console's off-line, Chief."

I should have transferred to a cargo drone...

no people, no complaints.

Hot coffee... black, double sweet.

Tell me, Quark.

Am I mistaken, or is business a little slow today?

Slow? It's been almost nonexistent

for the past three days.

Mmm. Who knows?

If things don't improve

you may be forced to close down.

Oh, you'd like that, wouldn't you?

Well, let's just say, without you around

my job would be considerably easier.

Without me around, you'd be forced

to find some other poor innocent to persecute.

Think about that while you sit here

gloating at my misfortune.

Quark!

You call this Kohlanese stew?

If your meal isn't satisfactory

I'm sure we could, uh, exchange it

for something more to your liking.

Aren't you the least bit curious

as to how it tastes?

Ugh! Ugh!

Now...

you served it.

You're going to eat it.

All right, that's enough.

I said, eat it!

I said...

that's enough.

Leave him alone.

Well, another satisfied customer.

It's these replicators.

If I don't get them fixed soon, they'll destroy my business.

Why not get O'Brien to fix them?

He has the replicators on the command level working perfectly.

I'm on his waiting list.

He assures me he'll get to them as soon as he can.

Mmm...

No telling when that will be.

The Chief's a very busy man.

Computer...

display a station layout.

Highlight locations of all repaired replicators

on command level.

Information restricted

to security clearance 5 and above.

Please enter security verification.

Clearance verified.

There you go, sir.

I think you'll find that more to your liking.

Very much appreciated, Mr. O'Brien.

Don't mention it, sir.

Unfortunately, there are plenty of replicators

around the station that still need looking after.

You all right, Chief?

I'm just a bit hot.

The environmental controls

must be acting up again.

Send my regards to Mrs. O'Brien.

Jake tells me she's a wonderful teacher.

Oh, that's nice to hear, sir.

She's flower units about the lad herself.

Excuse me?

Sir?

What was that you just said?

She's... quite fond of the lad herself.

Oh.

I'm glad to hear it.

Very good, sir.

Ladies.

Hello, Lieutenant.

Oh, I forgot how different it was.

How different what was?

Being female.

I haven't been one for over 80 years.

All this attention.

Imagine it must take some getting used to.

Actually, I find it quite enjoyable.

Major Kira.

Lieutenant Dax.

I'd be honored to have you join my little party...

as my guests, of course.

What's all this, Quark?

You cheat your 1,000th customer?

Who says Bajorans don't have a sense of humor?

Actually, uh, we're celebrating the repair

of the bar's replicator system.

Perhaps I could interest you

in a nice, double-whipped, I'danian spice pudding.

Oh, what do you think?

I think I'm due back at Ops

but, uh, go on.

Enjoy yourself.

Chief?

How can I help you, Major?

Looks like you're the one who could use a little help.

Oh, no, I'm fine, really.

I suppose this isn't a good time to tell you

that number three turbolift has broken down again.

Joking, Chief.

Major, lark's true pepper.

What?

Let birds go further loose maybe.

Shout easy play.

Chief, you're not making any sense.

Round the turbulent quick.

Well, close the reverse harbor.

A-Ankle try sound.

Reset gleaming.

Dinner to bug.

Chief, wait.

When?

Chief.

Computer, continue neural imaging scan

and stimulate visual cortex.

All visual responses normal.

Begin auditory stimuli.

No physiological damage.

All brain functions within normal parameters.

Nurse.

Yes?

Will you pull up Mr. O'Brien's

neurophysiological history, please?

Yes, Doctor.

What is that?

What's he written?

I wish I knew.

Strike limits

flame the dark true salt.

Please, Chief, take a seat.

Way link complete.

Way link!

What's wrong with him?

He appears to suffering from a form of aphasia.

It's a perceptual dysfunction

in which aural and visual stimuli

are incorrectly processed by the brain.

His actual thinking hasn't been affected

but he's incapable of expressing himself

or understanding others.

Victory strike limits frosted wake.

Simple hesitation.

I'm not sure I follow you, Doctor.

You say Mr. O'Brien is aphasiac

but all of his tests have come up negative.

Isn't aphasia

typically associated

with some kind of cranial trauma?

Yes. It can occur as a result of a stroke

or a blow to the head

but there's no evidence of that here.

Did you check the medical library

for any precedents?

And rechecked... nothing, so far.

You have any theories?

Not yet.

Find one.

Major Kira, get ahold of the Chief's personal duty log.

I want to know where he's been

and what he's done for the past 52 hours.

I've already examined it, Commander.

He's been all over this station.

Retrace his steps and see what you come up with.

Dax, you will temporarily assume Mr. O'Brien's duties.

Yes, uh... um...

Is there a problem, Lieutenant?

Lieutenant?

I'm sorry, Benjamin.

I'm unable to...

foolish assembled regal...

control weather.

Spontaneous development of aphasia

is virtually impossible.

Yet we saw Lieutenant Dax become aphasiac before our eyes.

This told me we were dealing with a disease

which only mimics aphasia, so I ran a full

neural synaptic comparison between Dax and O'Brien

and I found this in the temporal lobes of both patients.

A virus.

It imposes itself

within the established synaptic pathways

and then randomly reroutes them.

For example, when I look at this

a process occurs within my brain

which connects the stimulus to the word "tricorder."

This virus disrupts that process.

I'd see a tricorder

but I'd say something ridiculous, like "window."

Exactly.

Doctor, I think you should get over here.

Night the flow trade again.

You lost pile luck.

Away tunnel back the garden.

Doctor, I want this station

put under emergency quarantine immediately.

Yes, sir.

Dabo!

Quark, what is going on here?

What does it look like?

It looks like business as usual

but that's impossible

because all shops and businesses

have been closed until further notice.

Except, of course, for essential station operations.

For which this place hardly qualifies.

I don't think they'd agree.

This quarantine has everybody on edge, Constable.

Would you deprive them of a little harmless diversion?

They'd be safer in their quarters.

Quark, this Kohlian stew... magnificent.

Fortunately, my assistant, Rom, was able to fix the replicators.

Yes, very fortunate.

Jake...

I expected you home an hour ago.

Sorry. I was at Nog's.

Dad, about this quarantine...

it's going to be okay, isn't it?

It's just a precaution, nothing more.

I wish I shared your confidence, Commander.

Go straight home, son.

I'll see you at dinner.

Captain Jaheel, all visitors

have been confined to their ships.

Believe me, there is no place I'd rather be.

Then what are you doing here?

Commander, I officially request permission

to leave this station.

Request denied.

But none of my crew

has been affected by this virus of yours.

And, unless I depart at once

my whole cargo will be ruined.

Captain, I suggest you return to your ship now.

Please. I don't want to get sick.

I'm sorry, but until we can find a cure for this... thing

no one's going anywhere.

Computer, let's start with one Ferengi starduster, please.

Extra strong.

Perfect.

Uh...

I thought the front wheels were sticking a bit.

Unauthorized access

to crew quarters is a crime, Quark.

You could have just asked to use the replicators.

There's an old Ferengi saying... "Never ask when you can take."

Uh, how did you figure it out?

You claimed Rom fixed your replicators.

- So? - Rom's an idiot.

He couldn't fix a straw if it was bent.

You're right.

Rom is an idiot.

Remind me to get rid of him tomorrow.

Based on the levels of the virus found in the patients' blood

I believe it's being absorbed through ingestion.

You're saying it's in our food?

Well, that's not possible.

All the food on this station is replicated

and all the replicators use biofilters.

They automatically screen out contaminants

including viruses.

Major, I've analyzed samples from replicators

all over the station.

Food on the command level is contaminated.

But all of us here have eaten from those replicators.

How come we're not aphasic?

This virus is highly adaptable.

Its incubation period

seems to vary within each individual.

According to O'Brien's duty log

the last thing he did before becoming aphasic

was fix the command level replicators.

Get a repair crew over there to inspect the site.

Let's shut down those replicators.

Maybe we'll be able to limit further contamination.

I'm afraid that's not going to do it, sir.

I've been getting aphasic patients

from all over the station.

How is that possible?

You can thank Quark.

I caught him using a replicator

in one of the vacant crew quarters.

He was producing his entire menu out of there.

If this virus is present

within a large enough segment of the population

it could mean...

What is it, Doctor?

I just took an air sample.

The virus...

It's mutated into an airborne variety.

Which means?

Which means the whole station is infected.

Station Log, Stardate 46423.7.

Nearly 60% of DS9's population

has now contracted the aphasia virus.

We've initiated standard quarantine procedures

and are advising all incoming ships

to maintain their distance from the station

until further notice.

I found it in the replicator's pattern generator.

O'Brien must have accidentally triggered it

when he repaired the system.

According to Bashir, it introduced

an anomalous programming sequence

into the materialization subroutine.

In effect, it built the virus

directly into the replicated food

at a molecular level.

So what we have here is sabotage.

Cardassian sabotage.

How can you be sure?

Has a diboridium core for a power source.

That is Cardassian technology.

Bashir to Sisko.

Sisko here.

Commander, I think you'd better get down here to the infirmary

as soon as possible.

On my way.

You wanted to see me, Doctor?

Jake?

Left... become better...

control... entire hope.

We've converted some empty crew quarters

into a hospital ward.

He'll be well looked after.

I'll take him there myself.

Come on, Jake.

You're going to be all right.

Commander, when you've got a moment

I've found something I'd like to show you.

It'll be all right. Just lay back.

I know, but just lay back and relax.

Food... dabo... drinks...

money... hand... mine... give!

Well, Quark, I see even you

couldn't weasel your way clear of this one.

You underestimate the Ferengi immune system, Commander.

I'm merely here visiting my less fortunate customers

to make sure they're not faking the illness

to avoid paying their bills.

No one could be that devious.

I am.

You... gold... owe... me!

I... now... give!

Up.

We're doing everything possible.

I'll be back as soon as I can.

The virus is synthetic, Commander.

Its nucleotide sequence is too perfect.

It's clearly not natural.

You're saying the Cardassians

genetically engineered this thing?

Well, that's what I thought at first

but I've studied Cardassian genetic engineering.

They always build distinctive

monoclonial links into their DNA.

This virus has none of those features.

All right, then who made it?

Well, that's what I wanted to find out.

So I referenced all known DNA construction techniques

in the Federation records

and this protein series was the key.

It indicates...

Doctor! Who created this virus?

The Bajorans, sir.

I believe it must have been a terrorist plot

to sabotage the Cardassians while they were here.

The energy decay of the power core

indicates it dates back to the building of the station.

That's 18 years ago.

I suppose the Bajoran underground

could have smuggled it aboard during construction...

before I took over as Head of Security.

But why would the underground go to all the trouble

of planting a booby trap and not set it off?

Maybe they forgot.

No. More likely, they were captured

or killed before they could release it.

Or killed before they could release it.

We need to find out who created this virus.

You're our best hope.

18 years is a long time.

Besides, even if she

finds who did this, that's no guarantee they can help us.

We just have to hope they remember the antidote.

That's assuming they ever bothered to create one.

It had to be someone in the underground

familiar with genetic engineering.

18 years ago?

Sounds like something

Dekon Elig might have thought up.

How can I find him?

The last I heard he was in a Cardassian prison.

Where was he being held?

The Velos VII Internment Camp

but that was nine years ago.

And you have no idea where he is now?

Think, Galis. This is important.

I'm sorry, Kira, but it was all so long ago.

What is it, Jake?

Roll linger when life...

roll linger when...

What?

Other support, strong courage...

He's running a high fever.

Open way long.

Open way.

Doctor, we have an emergency in crew quarters.

How is he, Doctor?

Not good, I'm afraid.

The virus has attacked his autonomic nervous system.

Can he be stabilized?

He hasn't responded to neural stimulation.

I've given him 30cc's of corophizine

to avoid secondary infection

but so far, I've been unable to lower his fever.

What are his chances?

Unless I find some way to counteract the virus

he'll be dead in 12 hours.

Have you made any progress?

No.

I've tried base pair destabilizers

sequential disruption... nothing seems to affect it.

Sir, I've got seven other aphasic patients

displaying the same symptoms as O'Brien here

and I'm afraid this is only the beginning.

Keep searching, Doctor.

I hope Major Kira finds

whoever's responsible for creating this virus.

I'd like to meet that person myself.

This virus is a work of genius.

I'll try to arrange it for you.

Link established with the Bajoran Archival Records.

Locate files on Velos VII Internment Camp.

Ready.

Do you show a record of an inmate named Dekon Elig?

Affirmative.

Biographical data.

Dekon Elig, geneticist.

Former member of the Higa Metar sect

of the Bajoran underground.

Killed while attempting escape, Stardate 39355.

Certificate of Death on file.

No need to ask how you're doing.

Chasing after ghosts.

You have 12 hours to catch one.

And then?

People start dying.

Computer...

display Dekon Elig's Certificate of Death.

Identify signature of witness.

Certificate of Death was witnessed by Surmak Ren

Bajoran medical assistant.

Show me biographical data on Surmak Ren.

Dr. Surmak Ren.

Former member of the Higa Metar sect

of the Bajoran underground.

Repatriated to Bajor upon closing

of the Velos VII Internment Camp, Stardate 46302.

Current status unknown.

Dabo.

Any luck?

I haven't won a spin in hours.

Uh, care to place a friendly wager?

If it's your reputation you're thinking about

no one need ever know.

It has nothing to do with my reputation.

The truth is, I never...

learned the game.

You mean, you've sat here for all these years

and you don't even know how to gamble?

That's correct.

No wonder you always look so bored.

The rules are quite simple, actually.

I'd be happy to show them to you.

Some other time, perhaps.

Sisko needs me in Ops.

And, since the entire security force

has been stricken with aphasia

the Promenade is in a very vulnerable position.

How unfortunate.

Consider it a warning, Quark.

Because I'm holding you personally responsible

if anything turns up missing.

Is that understood?

Perfectly.

Hmm.

Dabo.

Computer, analyze test sample 37 delta.

Detail effects on viral containment.

Working. Analysis complete.

Sample 37 delta ineffective.

Viral protein sheath is unaffected.

Nucleotide sequence remains intact.

Computer, replay morning.

Command unclear.

Please repeat.

Glass lunch judge a bin to let it.

Command unclear.

Please repeat.

Computer, establish a link with the Bajoran Medical Index

for the, uh, Northwestern District.

Link established.

Access all information on Dr. Surmak Ren.

There are no records matching that name.

Try the Northeastern District... same search.

Dr. Surmak Ren, currently serving

as Chief Administrator of the Ilvian Medical Complex.

Computer, open a channel to the Ilvian Medical Complex

Administrator's office.

This is Dr. Surmak. And you are?

Major Kira Nerys

Bajoran liaison to Deep Space 9.

Ah, yes, the old Cardassian mining station.

How can I help you?

It depends.

On what?

On whether or not you helped Dekon Elig

plant an aphasia virus here 18 years ago.

I have no idea what you're talking about.

Look, Sisko, I'm a security officer... a good one...

but that doesn't make me qualified

to help you run station operations.

You're probably right, Constable.

But, as you can see, you're all I've got.

Commander...

Commander, I think I found our scientist.

Does he have an antidote?

I don't know. He broke the connection

the minute I mentioned the virus.

Major, you mind telling me where you're going?

To continue my conversation with Dr. Surmak, in person.

Major, I can't allow you to break quarantine.

We can't risk spreading the virus to Bajor.

I am well aware of that, Commander.

As a matter of fact

I don't intend to step foot on the planet.

Better let her go, Sisko.

She's all we've got.

Let's just hope there's someone left

to greet her when she returns.

Jake.

How's it going?

I've missed you.

I know things don't look too good right now

but they'll get better.

You have to believe that

because I'm not going to lose you, Jake.

You hear me?

I'm not going to lose you.

You better take a look at this.

We have activity on Docking Port 5.

I think a ship is about to depart.

Docking Port 5?

That's Jaheel's ship.

Put him on screen.

Captain, your ship

has not been cleared for departure.

The mooring clamps are locked

and I don't intend to release them.

I suggest you change your mind.

I'm taking aft thrusters to one half.

Captain, cut your engines

before you rip your ship apart.

He's not reducing power.

Jaheel, I'm ordering you to stand down.

Your orders are no concern of mine.

My entire crew has been confined to your hospital.

I must leave now, while I can still function.

Look, I understand that you're frightened

but, believe me, you're better off here.

You don't want to be out there alone

and get hit by the virus.

Don't worry about me, I'm fine.

And I plan to stay that way.

And if you think you're go...

We'll have to retract the clamps.

Once he's clear of the station

we can grab him with a tractor beam.

Damn.

What's wrong?

There's too much stress on the mooring clamps.

They're not retracting.

His aft isolation plate buckled.

His main power core's been ruptured.

If the internal fuel cells collapse

the whole ship will explode.

And take half the docking ring with it.

Computer, isolate a com line

to the Ilvian Medical Complex Administrator's office.

Line isolated.

Scan office for life-forms.

One life-form present.

Lock on and stand by to transport.

This is Dr. Surmak.

Hello again, Doctor.

Just checking to see you're in your office.

I have nothing to say to...

Hello again, Doctor.

This is outrageous.

I demand you return me

to my office immediately.

Relax, Doctor.

You won't be gone long.

Try to reestablish visual contact

with Jaheel's ship.

No response.

His com lines are down.

Bypass communications through a secondary grid.

See if you can switch to external pickups.

Got it.

His fire control systems don't appear to be working.

We have about 15 minutes

before the fuel cells collapse.

I hope you feel better than you look.

Must be that damn virus.

This is Sisko.

Any station personnel who can understand

what I'm saying, come to Ops immediately.

We need help up here.

We have to get that ship away from the station.

Why don't we explode the mooring clamps?

The blast should push the ship away from the docking ring.

We'll have to get down there and blow it manually.

I'll do it.

All right.

You can cross barrels.

All job appalled.

What was that?

Bread...

the arrive...

seen earlier.

Oh, I see.

Major, this is kidnapping.

Turn this ship around or, I swear, you will spend

the rest of your life in Kran-Tobol Prison.

Fine. But first, we need your help.

The aphasia virus is spreading through the station.

Why come to me?

You helped create the virus, didn't you?

No, I had practically nothing to do with it.

Dekon Elig created the virus.

I was merely his medical assistant.

That seems like a lifetime ago now.

I was only in the underground for six months

before we were captured.

I am not responsible for this.

I am not looking to place blame!

All I want is the antidote.

I don't know of any antidote.

If Dekon created one, he never told me.

Listen, Surmak.

I have a station full of dying people

and you are the closest thing there is

to an expert on this virus.

I sympathize, Major

but I don't think I can help you.

All right.

Then how about helping yourself?

Meaning what?

Meaning...

I've been infected with your virus, Doctor

so now you're infected, too.

To anyone who can hear me, this is Odo.

Sisko's infected.

I could really use some help here in Ops.

Do I detect a note of panic in your voice?

Quark.

Am I to believe that you're volunteering to help?

Who said anything about volunteering?

We can haggle over price later.

Now, um...

how may I be of use?

I need to get to Docking Port 5 now.

That ship's going to explode in five minutes.

I'll beam you over.

You?

Relax.

I served on a Ferengi freighter

for eight years.

All right.

I must have witnessed the procedure

hundreds of times.

Witnessed?

You mean to say you never handled the controls yourself?

Energizing.

Kira to Ops. Approaching Landing Pad 7.

Request clearance to initiate docking procedure.

Welcome back. I could use some help up here.

Quark, what are you

doing in Ops?

First thing I need to see

is your doctor's viral characterization research.

He was beginning to develop an antidote series.

Let's take a look at that.

Listen, Doctor, um

I'll be in Ops.

If you need me, use this string impact.

Lot show red intense.

I think you'd better sit down, Major.

Dog fellow distance.

Yeah, tell me about it.

Odo, you'd better hurry up.

That ship's going to explode in one minute.

Virum protein sheath.

Nucleotide sequence.

Yes.

That's right.

It's an adaptive, synaptic inhibitor.

Dekon was brilliant.

No doubt of that.

I think we've found

your antidote, Major.

40 seconds.

30 seconds. Hurry!

I know, I know.

20 seconds!

Ten seconds!

Odo? Quark to Odo.

You still with us?

Try not to sound too disappointed.

Now, about that little matter

of my hazard pay...

Why, you...

Come on. Come on.

Station Log, Stardate 46425.8.

With the help of Dr. Bashir's notes

Dr. Surmak was able to find an antidote for the aphasia virus.

We are continuing to administer it throughout the station

and things are slowly returning to normal.

Good to have you back, Chief.

Thank you, sir.

Coffee, black.

O'Brien!
