Star Trek: Deep Space Nine (1993–1999): Season 3, Episode 17 - Visionary - full transcript
While a Romulan delegation tries to get information about the Dominion, O'Brien gets visions of unpleasant things that are about to happen in the future.
It's all right, Chief.
You're going to be just fine.
What happened?
You were rerouting
a phase inducer
when one of the plasma conduits
blew out.
Oh.
Easy there, Chief.
You've got a mild case
of radiation poisoning.
I'll give you some hyronalin
which should
counteract the effects
but I do think
he should be restricted
to light duty
for the next few days.
Agreed.
Commander,
the transport's arrived
and they're requesting
permission to dock.
Route them to Docking Bay 12.
Inform the Romulan Delegation
we'll meet them there.
And Chief, "light duty"
means light.
I don't want to see you
crawling around
the Jefferies tube tonight
looking for power surges.
You won't get any arguments
today, Commander.
Ready, Major?
Promenade.
Du'cha KovaH!
EstaH! EstaH!
Constable, I wasn't aware
there were any Klingons
on the station.
They just arrived
a few hours ago.
It seems the main computer
on their freighter was damaged
and they need
a complete overhaul
before they can continue
back to the Klingon Empire.
How long is this overhaul
going to take?
Two days, at least.
The Romulan delegation
has just arrived
and they're going to be here
at least two days
while they study
our intelligence reports
on the Dominion.
I want you to keep a close eye
on the Klingons.
We don't need
any trouble right now.
Understood.
Let's go.
Come on.
Welcome to Deep Space 9.
I'm Commander Sisko, and this is
my First Officer, Major Kira.
I am Ruwon.
This is Karina.
We are ready for your report
on the Dominion.
We have arranged
quarters for you.
I know it's been a long trip,
so perhaps you'd like to...
We are not interested
in your accommodations,
Commander.
We are here for
your intelligence briefing--
nothing else.
Very well.
If you'll come this way.
This will be the foul line.
We need to put a marker
here on the floor.
I still don't see
how this is going to help
my business, Chief.
No, that's not right.
The number 20 needs
to be at the top.
Trust me, Quark.
Darts and bars go together
like bacon and eggs.
At least people order
bacon and eggs.
In all the years
I've been here,
no one has ever come
and asked to see the dart board.
Trust me, they will.
I just don't see
the appeal of this game.
No lasers, no holograms.
Just steel tips and feathers.
It's a game of skill, Quark.
And it's not easy.
Go ahead.
Try and get one
in the bull's-eye.
No!
Now what if one of those darts
had gotten into his eye?
Do you realize
I'd be liable for that?
Do you know how much
money an eye costs?
You're not supposed
to throw them like that.
You throw them gently.
One at a time.
Like this.
Chief O'Brien.
What is it, Quark?
The Klingons
just destroyed
two of my holosuites.
I need a maintenance crew
immediately.
Quark, this happens
every time the Klingons
come aboard the station.
Why don't you just keep
them out of the holosuites?
Did you ever say no
to a Klingon?
Besides, they pay me double.
Chief?
Chief!
Well, the pain you experienced
appears to be a muscle spasm
caused by a sudden decrease
in your serum calcium levels.
It's a common side effect
of radiation poisoning.
I'm giving you some
asinolyathin for the pain.
What about the vision I had?
Well, mild hallucinations
are also a fairly
common side effect
of radiation poisoning.
It was anything but mild.
I really felt
I was standing on the Promenade
watching myself
talking to Quark.
What was the conversation about?
He was complaining
about some Klingons.
He said they'd damaged
two of his holosuites.
Well, you do have one problem.
If all you can hallucinate about
is Quark's maintenance problems
you have a sadly
deficient fantasy life.
Well, thank you
for your professional opinion.
Oh, any time.
My doors are always open to you,
Chief.
The Dominion represents
the greatest threat
to the Alpha Quadrant
in the last century.
We need more information
on its military capabilities.
How many ships do they have?
Where are they deployed?
What are their plans
for the future?
Are they planning an attack?
We don't know any of that yet.
You have one of Founders
of the Dominion
on this very station.
He should be able to tell us
everything we need to know
about their intentions.
Odo is not one of the Founders.
Your own reports indicate
that a group of changelings
are the real
source of power
behind the Dominion.
Yes.
And Odo is a changeling.
But he's not
one of the Founders.
I fail to see the distinction.
Odo made a conscious choice
to stay here with us.
He has no loyalties
to the Dominion
and he has no information
about their plans.
We find that hard to believe.
It's the truth, whether you
choose to believe it or not.
Commander, we allowed you
to place one of our cloaking
devices on the Defiant
in exchange for information
regarding the Dominion.
Now you have the cloaking device
and we have very little.
We shouldn't have to remind you
of the importance
both our governments place
on continuing to carry out
this agreement.
It's the first treaty
between Romulus and
the Federation in many years.
I'm aware of that
and I'm willing to cooperate
with you in any way I can.
Very well, then.
We want to see
every piece of information
Starfleet has on the Dominion,
no matter how insignificant.
That includes
any classified reports
you may have made
to Starfleet Command.
I'll have to clear that
with Starfleet.
Then do it.
Chief O'Brien.
What is it, Quark?
The Klingons just destroyed
two of my holosuites.
I need a maintenance crew
immediately.
Quark, we go through this
every time Klingons
come aboard the station.
Why don't you ju...?
I think my holosuites
can wait.
It looks like you have
bigger problems.
I went over
the internal sensor logs
and I did find evidence
of a minor temporal
disturbance in Quark's
and another one later,
on the Promenade.
Both disturbances happened
at about the same time
as the Chief's experiences.
So, it would seem
that you did travel
into the future
and then returned
to the same moment
that you left.
Have you any idea what might
have caused this time shift?
Not yet.
I want to go over
the medical scans
Julian took of you earlier.
That dose of ionizing
radiation you received
might have something
to do with it.
HOW?
I'm not sure,
but it's a good place to start.
I have heard
a couple of theories
that ambient low-level radiation
could have a temporal...
Look out!
...effect
on radioactive isotopes.
Chief!
Mr. O'Brien.
I ran a micro-cellular scan
and detected minute damage
to his cerebrospinal
nerve cells
which might have been caused
by the time-shifting.
Can you repair it?
Yes, but the effect
is cumulative.
If you keep time-shifting,
there may come a point
where the damage
becomes irreparable.
Eventually, it might
even kill you.
Don't worry, Chief--
Dax is using
every scanner on the station
to hunt for any temporal
abnormalities.
Well, if anyone
can find the cause
of the time shifts, it's Dax.
Chief, do you have any idea
of how far into the future
you traveled?
No, sir.
There was nothing to indicate
that it was today
tomorrow, next week.
Well, this conference
with the Romulans
is not supposed to last
longer than three days.
In the meantime, I'll have Odo
tighten security around Quark's.
How are you feeling, Chief?
Better.
Good.
Commander, may I speak with you
for a minute?
Of course.
The Romulans want
to debrief everyone
who was on the Defiant
when it was captured
by the Founders.
They're also still not happy
with the sensor information
collected by the Defiant
so they want unrestricted
access to the Defiant
and they also want
complete access
to all our personal logs.
Personal logs are
out of the question
but they can have limited
access to the Defiant.
I'll let them
debrief us, as well.
I know they're pushing us, Major
but consider their position.
There have never been
any Romulan ships
in the Gamma Quadrant
in the Gamma Quadrant
so they've never
encountered the Dominion.
So they're completely dependent
on us for information.
Well, then maybe they should
send their own ships
through the Wormhole
and find out for themselves.
The Romulans generally
prefer to sit back
and pull the strings from
a distance, if they can.
This is one puppet who doesn't
like her strings pulled.
I know, but like Ruwon said
they've lived up
to their part of the bargain.
We have to do everything we can
to live up to ours.
All right, I'll draw up
a schedule of interviews
and I'll tell everyone
to cooperate.
And, Major, when you're
with the Romulans
try to be diplomatic.
I'm always diplomatic.
That is the most ridiculous
thing I ever heard
and I resent the implication.
You seem very agitated
for someone who's
proclaiming her innocence.
Indeed, your emotional state
would seem to indicate
that our theory is correct
and you did abandon
the Defiant prematurely
when it was attacked
by the Jem'Hadar.
When the Defiant was attacked
Odo and I were
trapped below decks.
There was a hand-to-hand
fight in the corridor.
I was wounded,
and I lost consciousness.
When I came to,
Odo had already put me
aboard the shuttle,
and we'd escaped.
I did not abandon
the ship prematurely.
Why didn't Odo try to help
the rest of the Defiant's crew?
Well, I'm sure he wanted to
but there was no way
to get to the Bridge, and...
Why were you in Odo's quarters
when the ship was attacked?
We were talking.
About what?
It's personal.
Do you often have
personal talks
with the changeling?
What business is that of yours?
We're trying to determine the
nature of your relationship.
You are the only member
of the Defiant's crew
who was not taken prisoner.
Why?
Did the Founders believe
Odo would react badly
if you were harmed?
Did they think you held
some kind of attraction to him?
Has Odo ever shown any kind
of physical interest
in you, Major?
That's it.
You can rip the cloaking device
out of the Defiant right now!
I am not answering
any more questions.
And I suggest you avoid
asking Odo those questions
or you may just find yourself
on the other side
of that bulkhead, floating home.
There.
That's the game.
Had enough?
One more.
Chief, that's the tenth game
we've played in a row.
Nothing's happening here
and I don't think anything
is going to happen.
By telling us about the fight,
you have changed the future.
Security's here, and Quark says
he won't let the Klingons
back in the bar.
There is not going
to be a fight.
I know, I know, but...
I've seen it, and I
can't shake the feeling
that it's going to happen
despite our precautions.
Something about
the way things look
the number of people.
There's something
a little too familiar
about everything.
All right, if it makes
you feel any better
I'll beat you
at another ten games.
But I can't help
getting the feeling...
Ach'cho korvak bataH!
Karagh, abeH.
You said you weren't
going to let
the Klingons back in the bar!
I didn't.
They were in the holosuites.
Besides, now they're
paying me triple.
Who let these filthy pahtk
in here?
Maybe we should
show them the way out.
And then...
What's his name?
Ruwon?
Ruwon started to insinuate
that...
you were...
That I was what?
Interested in me.
He said that?
Have you ever heard
anything more...
Ridiculous!
Exactly.
Quark to Security.
I've got a fight on my hands.
They're tearing my place apart.
Watch the Romulan!
All right, that's enough!
Get back!
Come on!
Move it.
Move it.
Let's go.
Come on now.
Miles?
Chief.
It's all right.
You collapsed outside Quark's
about an hour ago.
You're going to be fine.
No, I'm not.
In a few hours,
I'm going to be dead.
This is the panel
I saw myself open.
It looked like a phaser
or high-energy laser
came out of the bulkhead.
Nothing on the tricorder.
Just the standard conduits
and power juncture ports.
If there is something
dangerous in there
it could be cloaked
or have some dampening field
around it.
If you gentlemen will
step down the corridor
I'll open the panel
and take a look.
Don't worry.
I'll be careful.
It's all right.
Nothing.
You're sure
this is the right panel?
Absolutely.
Believe me,
I've a pretty vivid memory
of the whole thing.
Well... since it appears
that your first two time jumps
each moved you to about
five hours into the future
we could also assume
that the incident
you saw in this corridor
moved you to about five hours
into the future.
That means someone
will place a device
in this panel
in the next few hours.
In this panel
in the next few hours.
All these quarters
are vacant at the moment.
There are no vital power
conduits in this area.
No crucial defense systems.
Why would someone
want to booby-trap
a wall panel here?
I suggest we place
a surveillance device
in this corridor.
If anyone attempts
to tamper with the panel
we'll be able to detect it.
Dax to Sisko.
Sisko here.
Go ahead, Lieutenant.
Benjamin,
can you come to Ops?
I think I've found a clue
to Chief O'Brien's time-shifting.
We're on our way.
Keep me informed.
I've been scanning the area
around the station
out to a radius
of two kilometers.
I didn't find anything at first.
Then I started to scan some of
the lower subspace bandwidths.
I found traces of low-level
tetryon emissions.
I've never seen
an emission pattern
like that
outside of a neutron star.
Or a quantum singularity.
And singularities are
known to send out waves
of temporal displacement.
But if there is
a singularity nearby
why can't we find it?
It should also be affecting the
gravimetric field signatures.
I don't know.
Maybe it's buried so far down
in the subspace layers
that we can't detect it.
Assuming for the moment
that a singularity
is responsible
how do we combat
its effects on the Chief?
Temporal displacement
caused by a quantum singularity
most commonly affects
delta-series radioisotopes
which is exactly
what the Chief absorbed
during the conduit breach.
So you're saying that it
could be pulling O'Brien's body
like a magnet?
Exactly.
I think I may know a way
to neutralize the remaining
radioisotopes in your body.
Without the radiation
the temporal displacement
might stop.
It's going to take time.
You may experience
one or two more time shifts
before I can
complete the process.
When can we start?
Right away.
Keep trying to pinpoint
the singularity.
If it is out there,
we need to locate it
and find a way to get rid of it.
Right.
I wanted to let you know
I moved the Romulans
to different quarters.
Oh?
It's the replicators again.
I assigned a maintenance crew.
But in the meantime, I moved
the entire Romulan delegation
to section 47, level 2
in the Habitat Ring.
Section 47?
Yes.
ls something wrong?
The wall panel where O'Brien
saw himself being killed
is right outside those quarters.
Which means either the Romulans
are going to put a device
in the bulkhead themselves
or someone else will
possibly to be used
against the Romulans.
Should I move them
to other quarters?
No. That'll warn
whoever is responsible.
But inform Odo
of the change in quarters.
He already has that corridor
under surveillance.
Let's see
how this thing plays out
before we make
any further moves.
You have something, Constable?
Someone has planted
a class-3 surveillance device
behind the wall panel
we've been monitoring.
Were you able to see who it was?
No, we've been monitoring
the corridor constantly
for the past three hours.
No one's come anywhere
near the panel.
However, sensors did detect
a low-energy transporter beam
a short time ago.
They beamed the device
directly into the wall.
That's a delicate piece
of transporter work.
Yes, it is.
We haven't been able
to trace the beam
to its point of origin
but since there aren't
any ships nearby
I believe it originated
on the station.
Any Suspects?
Well, since it appears
to be a device
intended to conduct
covert surveillance
of the Romulans
my leading suspects
would be the Klingons.
Do you have any evidence
besides the fact that Klingons
hate Romulans?
Well, not yet, but don't worry.
I plan to investigate
the Klingons
the Bajorans, Quark,
the visiting Terrellians...
You think Quark
had something to do with this?
I always investigate Quark.
Looks like you're going
to cheat death, after all.
Round about this time,
you saw yourself being killed.
I feel like someone
just walked over my grave.
I mean, I've had a few brushes
with death in my career
but there was something
about watching
myself being killed--
of feeling my own neck
for a pulse that wasn't there.
Well, could have been worse.
Could have been me.
Here you are, gentlemen.
And how is DS9's
most famous fortune teller?
Don't call me that.
I haven't told anyone's fortune.
Oh, just a figure of speech.
On the other hand
if you should find yourself
in the future again
and you find yourself
passing by the dabo table
would it really hurt
to take a look
at the numbers
coming up on the wheel?
I could make it
worth your while.
Let's get out of here.
Just a thought.
Can you believe that?
I'm being pulled into the future
and all he can think about is...
Chief!
Oh, am I glad to see you.
What the hell
happened to me, Julian?
It was the, the radiation.
I didn't realize it had
damaged the basilar arteries
in your brain stem
until it was too late.
Well, why not?
It didn't show up
on any of the diagnostics.
I couldn't tell
what had happened
until I was doing the autopsy.
Autopsy-
Yeah, I just finished
doing it a few moments ago.
Do you want me
to show you the results?
No, no, no!
That's, that's all right.
Now, look, when you go
back to the past
ask me to perform
a basilar arterial scan
and since you're going
five hours back into the past
I should have enough time
to find the damage
and repair it before...
this happens.
Right.
How could you just let me die?
I didn't just let you die.
I did everything I could
to keep you alive
for over an hour
but your body just gave up.
Gave up?
I'm sorry, Chief.
But there comes a point
when the human body
just gives up.
Yeah, well, maybe
my Doctor wasn't...
Bashir to Infirmary.
I need a nurse and an emergency
med-kit here immediately.
We finally were able
to localize the transporter beam
and trace it back
to this location.
These quarters have
been vacant for weeks.
Somehow they overrode
the security lock
on the door to gain access.
So, what did they do?
Bring in a portable transporter
and beam
the surveillance equipment
into the bulkhead?
That was my first thought
but then I realized
that a portable transporter
is a rather large
and bulky piece of equipment
is a rather large
and bulky piece of equipment
to be carrying around the halls.
That's true.
So, then I began thinking
about...
the replicator.
Ah... they realigned
the matter-energy
conversion matrix.
Turning it
into a small transporter--
a very sophisticated,
very professional job.
So now we know
how they did it.
The next question is who.
I think I have the answer
to that as well.
Now, this device is manufactured
on Davlos III
a planet on the Klingon border.
In fact, Davlos does
over 90 percent
of its trade
with the Klingon Empire.
Oh, that's still very little
evidence to make an arrest.
Yes, it is
but then I contacted a friend
at Starfleet Intelligence
who used to be assigned
to the Federation Embassy
on the Klingon Homeworld.
He put me in contact
with a former Klingon operative
who is out of favor
with the current administration.
This former operative
sent me a series of reports...
Odo...
cut to the chase.
The three Klingons
now on the station
are part
of a covert strike force
that reports directly
to the Klingon High Council.
Why didn't you just say so?
Well, sometimes I have
to remind you
just how good I am.
Mm. So, Gowron sent
our three friends here
and they're conducting
surveillance
on the Romulan delegation.
Why?
Are they here to kill them?
Possibly.
It's also possible
that this is just
a routine intelligence-
gathering operation.
The high-energy laser
that killed O'Brien
is simply a booby trap
to prevent someone from
tampering with the device.
It's not meant
for assassination.
Well, in either case,
I think we have enough evidence
to at least hold the Klingons
for questioning, don't you?
Absolutely.
And I think I can question them
until the Romulan delegation
leaves the station.
Just be careful.
Commander,
there is no careful way
to question a Klingon.
I have...
I haven't given up.
I won't give up.
It's all right, Chief.
You're okay.
No, I'm not.
You need to run
a basilar arterial scan.
Why?
Because if you don't
I'm going to die
in less than five hours.
Who told you that?
You did.
In the future.
Oh.
Well, who am I
to argue with me?
Let me go!
This is an outrage.
We have done nothing.
We will have our vengeance
on all of you for this.
You are treating us
with dishonor.
We have done nothing wrong.
We take a very dim view of spies
and saboteurs on this station.
Now you slander us.
When my family finds out
what you have done
they will come here
and kill you.
I doubt that very much.
The only people
who will be coming here
are your friends
in Klingon Intelligence.
And from what I understand
they don't like being
embarrassed by operatives
who fail in their missions.
However, should you suddenly
feel like cooperating
I may be persuaded
to let you go
without contacting your friends
in Intelligence.
May be.
So how are you feeling, Chief?
Better, sir.
I've eliminated
almost all the radioisotopes
from his body.
Have to wait a couple more hours
before I give him
the last treatment.
But after that, there should be
no more time-shifting.
What about
the quantum singularity?
We've been able to track it
by using its tetryon emissions
as a guide.
It seems to be orbiting
Deep Space 9
in a roughly elliptical fashion.
At certain points in its orbit,
the singularity radiates
temporal energy
at a specific wavelength.
That seems to be
what triggers my time shifts.
Is there any way
to break it out of its orbit
and send it on its way?
Well, we were hoping
to station...
Come on, come on.
Hurry up.
We don't have much time!
Prepare to seal the hatch
and release the docking clamps.
Move quickly.
Let's go.
All the way back.
Move quickly.
Come on.
Initiating emergency
escape protocol.
Hang on,
I'm going to full impulse.
Now what?
You're here!
Look, I don't know
what happened.
I was asleep in bed when
the whole station was rocked
by an explosion.
Before I could get to Ops,
the evacuation alarm sounded.
And the com systems were down.
I got as many people
as I could in here.
I don't know what happened
to the others.
When you go back, you have
to find out what happened
and stop it.
My God!
Chief, what's wrong?
We've got a new problem, sir.
Did you see anything
from the runabout
that would indicate
how the station was destroyed?
There were a series
of explosions
that rippled across
the Habitat Ring.
But it all happened so fast
I couldn't get a clear sense
of exactly what was going on.
Could you tell if you were
looking at internal explosions
which might indicate some kind
of sabotage or accident
or external explosions,
which might indicate
we were under attack?
No. No, I'm not sure.
Do you remember seeing
any other ships nearby?
No, but I had a very limited
view of the area.
Well, it looks
like, at this point
we can't rule anything out.
Agreed.
Make preparations
to evacuate the station.
Do it quietly.
Do it quietly.
If the destruction
of the station
is the result
of an attack or sabotage
we don't want
to alarm our enemy
and make him trigger events
we're trying to avoid.
Begin a complete systems check
of everything on the station
that could potentially
cause this kind of explosion.
Right.
Commander...
there might be another way
to find out what's going on.
If I could travel
into the future again--
this time just before
the destruction of DS9--
I might be able to find out
what's going to happen
then return to the present
in time for us to prevent it
from happening.
If you could flood my body
with high concentrations
of delta-series radioisotopes,
it might trigger
a time shift into the future.
Possibly,
but those isotopes are toxic.
It could cause permanent damage
to your nervous system.
It might even kill you.
Well, if the future happens
the way I saw it happen
a lot of people are
going to get killed
when the station explodes.
It's a risk I'm willing to take.
Even if you're able
to initiate a time jump
each time you traveled
into the future
you've always gone five hours.
How do you propose to shorten
the length of a jump?
Well, there might be a link
between the temporal frequency
of the singularity
and the length
of the time shift.
We might be able to calibrate
the decay constant
of the isotope
that we inject you with
to match the frequency
of the singularity.
And with a few minor adjustments
we can control
how far you jump
into the future.
Exactly.
All right.
But if you can't do it
within two hours
I'm going to begin
to evacuate the station.
Understood.
Now, when you activate
this device
it'll inject you with a two-rad
dose of delta isotopes.
Now, if our calculations
are right
that should put you about
three hours into the future.
What's the margin of error?
Plus or minus half an hour,
I'd say.
But that's the best we could do.
Now, it's already set
for the return trip.
So all you have to do
is activate it again
to return to the present.
Right.
And remember,
don't wait too long.
Your body will be experiencing
symptoms
of severe radiation poisoning.
If you don't get treatment,
it will kill you.
I won't forget.
Good.
Julian, there's a...
a message in my quarters
for Keiko if...
I understand, Miles.
0200.
That's three and a half hours
into the future.
Miles, Miles!
Wake up!
What?
Computer, lights.
Oh, no, not you again.
What is it now?
Listen to me.
I've jumped ahead
and seen your future.
Don't ask me how,
it'll take too long to explain.
There's going to be a disaster.
DS9 will be destroyed.
Destroyed? How?
I don't know.
That's why I'm here.
I have to find out
what's going to happen
and then travel back
into the past and prevent it.
You look pretty bad.
It's the radiation.
Well, if you feel bad
and you're my past self
shouldn't I feel bad, too?
I hate temporal mechanics.
Let's get down to Ops
and see what's going on.
Help me up.
Run a sensor sweep
of the entire station.
Look for anything
that might indicate a...
Report!
A Romulan war-bird just
de-cloaked off of Lower Pylon 2.
They've taken out
our shield generators.
On screen.
Lock phasers and return fire.
They've hit the fusion reactor.
Main power's down.
Defense systems off-line.
Try to reroute phasers through
the emergency power couplings.
Miles, you've got your answer.
The quantum singularity
that's been orbiting
the station--
it's the Romulans.
Are you listening?
The Romulans use
a confined singularity
to power their warp core.
That's what we've
been detecting.
That's what's causing
the time shifts.
You must go back and tell them
to put up the shields
and stand by for an attack.
I can't.
I can't get through
another shift.
It's the radiation poisoning,
it...
You go.
Just activate it.
It's set for the return trip.
Me?
I don't belong there.
I'm you... you're me...
It does... doesn't matter.
Just go.
Go!
Chief!
What happened?
It worked.
O'Brien to Sisko.
Go ahead, Chief.
I've been to the future,
Commander.
The quantum singularity
off the station
is actually in the warp core
of a cloaked Romulan war-bird.
They're going to de-cloak and
fire on us in a matter of hours.
Understood, Chief.
Raise shields.
Stand by weapons systems.
I don't understand it.
Your body should be flooded
with delta-series radiation
but there's only a tiny
amount in your tissues.
Your metabolic readings
are different.
What happened?
There's been a... a change.
There's been a... a change.
Uh... I really have
nothing else to say.
I think you're lying, Quark.
About what part?
All of it.
Well, at least I'm consistent.
Quark, you can leave.
Thank you.
I know you have a cloaked
war-bird orbiting the station.
And I know that you're
planning an attack.
At first, I couldn't
understand why
and then I remembered
what you said
about the Dominion--
how they were the greatest
threat to the Alpha Quadrant
in the last century.
If you really believed that
then the only way you
could ever be truly safe
from the Dominion would be
to collapse the wormhole.
But you knew we wouldn't
just sit by
and watch while you did it.
So you had to destroy
the station, too.
That way,
there'd be no witnesses.
Everyone would assume
that Deep Space 9 was destroyed
by what appeared to be
the accidental collapse
of the Wormhole.
An interesting...
theory, Commander.
But that's all it is,
a theory.
That's right.
But I'll tell you
what's not a theory.
We tracked the tetryon emissions
back to your war-bird
and I have about 50 photon
torpedoes locked onto it
right now.
I think it's time we left.
I couldn't agree more.
Constable, will you please
escort our... guests
to the nearest transporter room?
If you'll come with me.
So you're telling me
that you remember
playing this game
with me in the future?
Right.
All right, what am I
going to hit?
20, outer ring.
Why, that's remarkable.
It's also a little disturbing.
I have this nagging feeling
that I don't really belong here.
This isn't really my life.
You know, maybe this life
belongs
to that other Miles O'Brien.
Listen, Chief, whether you
are living in the past
or the present,
you are Miles O'Brien.
The only difference is
you have a few memories
the other one didn't have.
Well, I think I'll go to bed.
I'm still kind of tired.
Now, that sounds
like a good idea.
Quark.
Dabo.
Dabo?
Dabo!
Wait, Chief, wait!
You're going to be just fine.
What happened?
You were rerouting
a phase inducer
when one of the plasma conduits
blew out.
Oh.
Easy there, Chief.
You've got a mild case
of radiation poisoning.
I'll give you some hyronalin
which should
counteract the effects
but I do think
he should be restricted
to light duty
for the next few days.
Agreed.
Commander,
the transport's arrived
and they're requesting
permission to dock.
Route them to Docking Bay 12.
Inform the Romulan Delegation
we'll meet them there.
And Chief, "light duty"
means light.
I don't want to see you
crawling around
the Jefferies tube tonight
looking for power surges.
You won't get any arguments
today, Commander.
Ready, Major?
Promenade.
Du'cha KovaH!
EstaH! EstaH!
Constable, I wasn't aware
there were any Klingons
on the station.
They just arrived
a few hours ago.
It seems the main computer
on their freighter was damaged
and they need
a complete overhaul
before they can continue
back to the Klingon Empire.
How long is this overhaul
going to take?
Two days, at least.
The Romulan delegation
has just arrived
and they're going to be here
at least two days
while they study
our intelligence reports
on the Dominion.
I want you to keep a close eye
on the Klingons.
We don't need
any trouble right now.
Understood.
Let's go.
Come on.
Welcome to Deep Space 9.
I'm Commander Sisko, and this is
my First Officer, Major Kira.
I am Ruwon.
This is Karina.
We are ready for your report
on the Dominion.
We have arranged
quarters for you.
I know it's been a long trip,
so perhaps you'd like to...
We are not interested
in your accommodations,
Commander.
We are here for
your intelligence briefing--
nothing else.
Very well.
If you'll come this way.
This will be the foul line.
We need to put a marker
here on the floor.
I still don't see
how this is going to help
my business, Chief.
No, that's not right.
The number 20 needs
to be at the top.
Trust me, Quark.
Darts and bars go together
like bacon and eggs.
At least people order
bacon and eggs.
In all the years
I've been here,
no one has ever come
and asked to see the dart board.
Trust me, they will.
I just don't see
the appeal of this game.
No lasers, no holograms.
Just steel tips and feathers.
It's a game of skill, Quark.
And it's not easy.
Go ahead.
Try and get one
in the bull's-eye.
No!
Now what if one of those darts
had gotten into his eye?
Do you realize
I'd be liable for that?
Do you know how much
money an eye costs?
You're not supposed
to throw them like that.
You throw them gently.
One at a time.
Like this.
Chief O'Brien.
What is it, Quark?
The Klingons
just destroyed
two of my holosuites.
I need a maintenance crew
immediately.
Quark, this happens
every time the Klingons
come aboard the station.
Why don't you just keep
them out of the holosuites?
Did you ever say no
to a Klingon?
Besides, they pay me double.
Chief?
Chief!
Well, the pain you experienced
appears to be a muscle spasm
caused by a sudden decrease
in your serum calcium levels.
It's a common side effect
of radiation poisoning.
I'm giving you some
asinolyathin for the pain.
What about the vision I had?
Well, mild hallucinations
are also a fairly
common side effect
of radiation poisoning.
It was anything but mild.
I really felt
I was standing on the Promenade
watching myself
talking to Quark.
What was the conversation about?
He was complaining
about some Klingons.
He said they'd damaged
two of his holosuites.
Well, you do have one problem.
If all you can hallucinate about
is Quark's maintenance problems
you have a sadly
deficient fantasy life.
Well, thank you
for your professional opinion.
Oh, any time.
My doors are always open to you,
Chief.
The Dominion represents
the greatest threat
to the Alpha Quadrant
in the last century.
We need more information
on its military capabilities.
How many ships do they have?
Where are they deployed?
What are their plans
for the future?
Are they planning an attack?
We don't know any of that yet.
You have one of Founders
of the Dominion
on this very station.
He should be able to tell us
everything we need to know
about their intentions.
Odo is not one of the Founders.
Your own reports indicate
that a group of changelings
are the real
source of power
behind the Dominion.
Yes.
And Odo is a changeling.
But he's not
one of the Founders.
I fail to see the distinction.
Odo made a conscious choice
to stay here with us.
He has no loyalties
to the Dominion
and he has no information
about their plans.
We find that hard to believe.
It's the truth, whether you
choose to believe it or not.
Commander, we allowed you
to place one of our cloaking
devices on the Defiant
in exchange for information
regarding the Dominion.
Now you have the cloaking device
and we have very little.
We shouldn't have to remind you
of the importance
both our governments place
on continuing to carry out
this agreement.
It's the first treaty
between Romulus and
the Federation in many years.
I'm aware of that
and I'm willing to cooperate
with you in any way I can.
Very well, then.
We want to see
every piece of information
Starfleet has on the Dominion,
no matter how insignificant.
That includes
any classified reports
you may have made
to Starfleet Command.
I'll have to clear that
with Starfleet.
Then do it.
Chief O'Brien.
What is it, Quark?
The Klingons just destroyed
two of my holosuites.
I need a maintenance crew
immediately.
Quark, we go through this
every time Klingons
come aboard the station.
Why don't you ju...?
I think my holosuites
can wait.
It looks like you have
bigger problems.
I went over
the internal sensor logs
and I did find evidence
of a minor temporal
disturbance in Quark's
and another one later,
on the Promenade.
Both disturbances happened
at about the same time
as the Chief's experiences.
So, it would seem
that you did travel
into the future
and then returned
to the same moment
that you left.
Have you any idea what might
have caused this time shift?
Not yet.
I want to go over
the medical scans
Julian took of you earlier.
That dose of ionizing
radiation you received
might have something
to do with it.
HOW?
I'm not sure,
but it's a good place to start.
I have heard
a couple of theories
that ambient low-level radiation
could have a temporal...
Look out!
...effect
on radioactive isotopes.
Chief!
Mr. O'Brien.
I ran a micro-cellular scan
and detected minute damage
to his cerebrospinal
nerve cells
which might have been caused
by the time-shifting.
Can you repair it?
Yes, but the effect
is cumulative.
If you keep time-shifting,
there may come a point
where the damage
becomes irreparable.
Eventually, it might
even kill you.
Don't worry, Chief--
Dax is using
every scanner on the station
to hunt for any temporal
abnormalities.
Well, if anyone
can find the cause
of the time shifts, it's Dax.
Chief, do you have any idea
of how far into the future
you traveled?
No, sir.
There was nothing to indicate
that it was today
tomorrow, next week.
Well, this conference
with the Romulans
is not supposed to last
longer than three days.
In the meantime, I'll have Odo
tighten security around Quark's.
How are you feeling, Chief?
Better.
Good.
Commander, may I speak with you
for a minute?
Of course.
The Romulans want
to debrief everyone
who was on the Defiant
when it was captured
by the Founders.
They're also still not happy
with the sensor information
collected by the Defiant
so they want unrestricted
access to the Defiant
and they also want
complete access
to all our personal logs.
Personal logs are
out of the question
but they can have limited
access to the Defiant.
I'll let them
debrief us, as well.
I know they're pushing us, Major
but consider their position.
There have never been
any Romulan ships
in the Gamma Quadrant
in the Gamma Quadrant
so they've never
encountered the Dominion.
So they're completely dependent
on us for information.
Well, then maybe they should
send their own ships
through the Wormhole
and find out for themselves.
The Romulans generally
prefer to sit back
and pull the strings from
a distance, if they can.
This is one puppet who doesn't
like her strings pulled.
I know, but like Ruwon said
they've lived up
to their part of the bargain.
We have to do everything we can
to live up to ours.
All right, I'll draw up
a schedule of interviews
and I'll tell everyone
to cooperate.
And, Major, when you're
with the Romulans
try to be diplomatic.
I'm always diplomatic.
That is the most ridiculous
thing I ever heard
and I resent the implication.
You seem very agitated
for someone who's
proclaiming her innocence.
Indeed, your emotional state
would seem to indicate
that our theory is correct
and you did abandon
the Defiant prematurely
when it was attacked
by the Jem'Hadar.
When the Defiant was attacked
Odo and I were
trapped below decks.
There was a hand-to-hand
fight in the corridor.
I was wounded,
and I lost consciousness.
When I came to,
Odo had already put me
aboard the shuttle,
and we'd escaped.
I did not abandon
the ship prematurely.
Why didn't Odo try to help
the rest of the Defiant's crew?
Well, I'm sure he wanted to
but there was no way
to get to the Bridge, and...
Why were you in Odo's quarters
when the ship was attacked?
We were talking.
About what?
It's personal.
Do you often have
personal talks
with the changeling?
What business is that of yours?
We're trying to determine the
nature of your relationship.
You are the only member
of the Defiant's crew
who was not taken prisoner.
Why?
Did the Founders believe
Odo would react badly
if you were harmed?
Did they think you held
some kind of attraction to him?
Has Odo ever shown any kind
of physical interest
in you, Major?
That's it.
You can rip the cloaking device
out of the Defiant right now!
I am not answering
any more questions.
And I suggest you avoid
asking Odo those questions
or you may just find yourself
on the other side
of that bulkhead, floating home.
There.
That's the game.
Had enough?
One more.
Chief, that's the tenth game
we've played in a row.
Nothing's happening here
and I don't think anything
is going to happen.
By telling us about the fight,
you have changed the future.
Security's here, and Quark says
he won't let the Klingons
back in the bar.
There is not going
to be a fight.
I know, I know, but...
I've seen it, and I
can't shake the feeling
that it's going to happen
despite our precautions.
Something about
the way things look
the number of people.
There's something
a little too familiar
about everything.
All right, if it makes
you feel any better
I'll beat you
at another ten games.
But I can't help
getting the feeling...
Ach'cho korvak bataH!
Karagh, abeH.
You said you weren't
going to let
the Klingons back in the bar!
I didn't.
They were in the holosuites.
Besides, now they're
paying me triple.
Who let these filthy pahtk
in here?
Maybe we should
show them the way out.
And then...
What's his name?
Ruwon?
Ruwon started to insinuate
that...
you were...
That I was what?
Interested in me.
He said that?
Have you ever heard
anything more...
Ridiculous!
Exactly.
Quark to Security.
I've got a fight on my hands.
They're tearing my place apart.
Watch the Romulan!
All right, that's enough!
Get back!
Come on!
Move it.
Move it.
Let's go.
Come on now.
Miles?
Chief.
It's all right.
You collapsed outside Quark's
about an hour ago.
You're going to be fine.
No, I'm not.
In a few hours,
I'm going to be dead.
This is the panel
I saw myself open.
It looked like a phaser
or high-energy laser
came out of the bulkhead.
Nothing on the tricorder.
Just the standard conduits
and power juncture ports.
If there is something
dangerous in there
it could be cloaked
or have some dampening field
around it.
If you gentlemen will
step down the corridor
I'll open the panel
and take a look.
Don't worry.
I'll be careful.
It's all right.
Nothing.
You're sure
this is the right panel?
Absolutely.
Believe me,
I've a pretty vivid memory
of the whole thing.
Well... since it appears
that your first two time jumps
each moved you to about
five hours into the future
we could also assume
that the incident
you saw in this corridor
moved you to about five hours
into the future.
That means someone
will place a device
in this panel
in the next few hours.
In this panel
in the next few hours.
All these quarters
are vacant at the moment.
There are no vital power
conduits in this area.
No crucial defense systems.
Why would someone
want to booby-trap
a wall panel here?
I suggest we place
a surveillance device
in this corridor.
If anyone attempts
to tamper with the panel
we'll be able to detect it.
Dax to Sisko.
Sisko here.
Go ahead, Lieutenant.
Benjamin,
can you come to Ops?
I think I've found a clue
to Chief O'Brien's time-shifting.
We're on our way.
Keep me informed.
I've been scanning the area
around the station
out to a radius
of two kilometers.
I didn't find anything at first.
Then I started to scan some of
the lower subspace bandwidths.
I found traces of low-level
tetryon emissions.
I've never seen
an emission pattern
like that
outside of a neutron star.
Or a quantum singularity.
And singularities are
known to send out waves
of temporal displacement.
But if there is
a singularity nearby
why can't we find it?
It should also be affecting the
gravimetric field signatures.
I don't know.
Maybe it's buried so far down
in the subspace layers
that we can't detect it.
Assuming for the moment
that a singularity
is responsible
how do we combat
its effects on the Chief?
Temporal displacement
caused by a quantum singularity
most commonly affects
delta-series radioisotopes
which is exactly
what the Chief absorbed
during the conduit breach.
So you're saying that it
could be pulling O'Brien's body
like a magnet?
Exactly.
I think I may know a way
to neutralize the remaining
radioisotopes in your body.
Without the radiation
the temporal displacement
might stop.
It's going to take time.
You may experience
one or two more time shifts
before I can
complete the process.
When can we start?
Right away.
Keep trying to pinpoint
the singularity.
If it is out there,
we need to locate it
and find a way to get rid of it.
Right.
I wanted to let you know
I moved the Romulans
to different quarters.
Oh?
It's the replicators again.
I assigned a maintenance crew.
But in the meantime, I moved
the entire Romulan delegation
to section 47, level 2
in the Habitat Ring.
Section 47?
Yes.
ls something wrong?
The wall panel where O'Brien
saw himself being killed
is right outside those quarters.
Which means either the Romulans
are going to put a device
in the bulkhead themselves
or someone else will
possibly to be used
against the Romulans.
Should I move them
to other quarters?
No. That'll warn
whoever is responsible.
But inform Odo
of the change in quarters.
He already has that corridor
under surveillance.
Let's see
how this thing plays out
before we make
any further moves.
You have something, Constable?
Someone has planted
a class-3 surveillance device
behind the wall panel
we've been monitoring.
Were you able to see who it was?
No, we've been monitoring
the corridor constantly
for the past three hours.
No one's come anywhere
near the panel.
However, sensors did detect
a low-energy transporter beam
a short time ago.
They beamed the device
directly into the wall.
That's a delicate piece
of transporter work.
Yes, it is.
We haven't been able
to trace the beam
to its point of origin
but since there aren't
any ships nearby
I believe it originated
on the station.
Any Suspects?
Well, since it appears
to be a device
intended to conduct
covert surveillance
of the Romulans
my leading suspects
would be the Klingons.
Do you have any evidence
besides the fact that Klingons
hate Romulans?
Well, not yet, but don't worry.
I plan to investigate
the Klingons
the Bajorans, Quark,
the visiting Terrellians...
You think Quark
had something to do with this?
I always investigate Quark.
Looks like you're going
to cheat death, after all.
Round about this time,
you saw yourself being killed.
I feel like someone
just walked over my grave.
I mean, I've had a few brushes
with death in my career
but there was something
about watching
myself being killed--
of feeling my own neck
for a pulse that wasn't there.
Well, could have been worse.
Could have been me.
Here you are, gentlemen.
And how is DS9's
most famous fortune teller?
Don't call me that.
I haven't told anyone's fortune.
Oh, just a figure of speech.
On the other hand
if you should find yourself
in the future again
and you find yourself
passing by the dabo table
would it really hurt
to take a look
at the numbers
coming up on the wheel?
I could make it
worth your while.
Let's get out of here.
Just a thought.
Can you believe that?
I'm being pulled into the future
and all he can think about is...
Chief!
Oh, am I glad to see you.
What the hell
happened to me, Julian?
It was the, the radiation.
I didn't realize it had
damaged the basilar arteries
in your brain stem
until it was too late.
Well, why not?
It didn't show up
on any of the diagnostics.
I couldn't tell
what had happened
until I was doing the autopsy.
Autopsy-
Yeah, I just finished
doing it a few moments ago.
Do you want me
to show you the results?
No, no, no!
That's, that's all right.
Now, look, when you go
back to the past
ask me to perform
a basilar arterial scan
and since you're going
five hours back into the past
I should have enough time
to find the damage
and repair it before...
this happens.
Right.
How could you just let me die?
I didn't just let you die.
I did everything I could
to keep you alive
for over an hour
but your body just gave up.
Gave up?
I'm sorry, Chief.
But there comes a point
when the human body
just gives up.
Yeah, well, maybe
my Doctor wasn't...
Bashir to Infirmary.
I need a nurse and an emergency
med-kit here immediately.
We finally were able
to localize the transporter beam
and trace it back
to this location.
These quarters have
been vacant for weeks.
Somehow they overrode
the security lock
on the door to gain access.
So, what did they do?
Bring in a portable transporter
and beam
the surveillance equipment
into the bulkhead?
That was my first thought
but then I realized
that a portable transporter
is a rather large
and bulky piece of equipment
is a rather large
and bulky piece of equipment
to be carrying around the halls.
That's true.
So, then I began thinking
about...
the replicator.
Ah... they realigned
the matter-energy
conversion matrix.
Turning it
into a small transporter--
a very sophisticated,
very professional job.
So now we know
how they did it.
The next question is who.
I think I have the answer
to that as well.
Now, this device is manufactured
on Davlos III
a planet on the Klingon border.
In fact, Davlos does
over 90 percent
of its trade
with the Klingon Empire.
Oh, that's still very little
evidence to make an arrest.
Yes, it is
but then I contacted a friend
at Starfleet Intelligence
who used to be assigned
to the Federation Embassy
on the Klingon Homeworld.
He put me in contact
with a former Klingon operative
who is out of favor
with the current administration.
This former operative
sent me a series of reports...
Odo...
cut to the chase.
The three Klingons
now on the station
are part
of a covert strike force
that reports directly
to the Klingon High Council.
Why didn't you just say so?
Well, sometimes I have
to remind you
just how good I am.
Mm. So, Gowron sent
our three friends here
and they're conducting
surveillance
on the Romulan delegation.
Why?
Are they here to kill them?
Possibly.
It's also possible
that this is just
a routine intelligence-
gathering operation.
The high-energy laser
that killed O'Brien
is simply a booby trap
to prevent someone from
tampering with the device.
It's not meant
for assassination.
Well, in either case,
I think we have enough evidence
to at least hold the Klingons
for questioning, don't you?
Absolutely.
And I think I can question them
until the Romulan delegation
leaves the station.
Just be careful.
Commander,
there is no careful way
to question a Klingon.
I have...
I haven't given up.
I won't give up.
It's all right, Chief.
You're okay.
No, I'm not.
You need to run
a basilar arterial scan.
Why?
Because if you don't
I'm going to die
in less than five hours.
Who told you that?
You did.
In the future.
Oh.
Well, who am I
to argue with me?
Let me go!
This is an outrage.
We have done nothing.
We will have our vengeance
on all of you for this.
You are treating us
with dishonor.
We have done nothing wrong.
We take a very dim view of spies
and saboteurs on this station.
Now you slander us.
When my family finds out
what you have done
they will come here
and kill you.
I doubt that very much.
The only people
who will be coming here
are your friends
in Klingon Intelligence.
And from what I understand
they don't like being
embarrassed by operatives
who fail in their missions.
However, should you suddenly
feel like cooperating
I may be persuaded
to let you go
without contacting your friends
in Intelligence.
May be.
So how are you feeling, Chief?
Better, sir.
I've eliminated
almost all the radioisotopes
from his body.
Have to wait a couple more hours
before I give him
the last treatment.
But after that, there should be
no more time-shifting.
What about
the quantum singularity?
We've been able to track it
by using its tetryon emissions
as a guide.
It seems to be orbiting
Deep Space 9
in a roughly elliptical fashion.
At certain points in its orbit,
the singularity radiates
temporal energy
at a specific wavelength.
That seems to be
what triggers my time shifts.
Is there any way
to break it out of its orbit
and send it on its way?
Well, we were hoping
to station...
Come on, come on.
Hurry up.
We don't have much time!
Prepare to seal the hatch
and release the docking clamps.
Move quickly.
Let's go.
All the way back.
Move quickly.
Come on.
Initiating emergency
escape protocol.
Hang on,
I'm going to full impulse.
Now what?
You're here!
Look, I don't know
what happened.
I was asleep in bed when
the whole station was rocked
by an explosion.
Before I could get to Ops,
the evacuation alarm sounded.
And the com systems were down.
I got as many people
as I could in here.
I don't know what happened
to the others.
When you go back, you have
to find out what happened
and stop it.
My God!
Chief, what's wrong?
We've got a new problem, sir.
Did you see anything
from the runabout
that would indicate
how the station was destroyed?
There were a series
of explosions
that rippled across
the Habitat Ring.
But it all happened so fast
I couldn't get a clear sense
of exactly what was going on.
Could you tell if you were
looking at internal explosions
which might indicate some kind
of sabotage or accident
or external explosions,
which might indicate
we were under attack?
No. No, I'm not sure.
Do you remember seeing
any other ships nearby?
No, but I had a very limited
view of the area.
Well, it looks
like, at this point
we can't rule anything out.
Agreed.
Make preparations
to evacuate the station.
Do it quietly.
Do it quietly.
If the destruction
of the station
is the result
of an attack or sabotage
we don't want
to alarm our enemy
and make him trigger events
we're trying to avoid.
Begin a complete systems check
of everything on the station
that could potentially
cause this kind of explosion.
Right.
Commander...
there might be another way
to find out what's going on.
If I could travel
into the future again--
this time just before
the destruction of DS9--
I might be able to find out
what's going to happen
then return to the present
in time for us to prevent it
from happening.
If you could flood my body
with high concentrations
of delta-series radioisotopes,
it might trigger
a time shift into the future.
Possibly,
but those isotopes are toxic.
It could cause permanent damage
to your nervous system.
It might even kill you.
Well, if the future happens
the way I saw it happen
a lot of people are
going to get killed
when the station explodes.
It's a risk I'm willing to take.
Even if you're able
to initiate a time jump
each time you traveled
into the future
you've always gone five hours.
How do you propose to shorten
the length of a jump?
Well, there might be a link
between the temporal frequency
of the singularity
and the length
of the time shift.
We might be able to calibrate
the decay constant
of the isotope
that we inject you with
to match the frequency
of the singularity.
And with a few minor adjustments
we can control
how far you jump
into the future.
Exactly.
All right.
But if you can't do it
within two hours
I'm going to begin
to evacuate the station.
Understood.
Now, when you activate
this device
it'll inject you with a two-rad
dose of delta isotopes.
Now, if our calculations
are right
that should put you about
three hours into the future.
What's the margin of error?
Plus or minus half an hour,
I'd say.
But that's the best we could do.
Now, it's already set
for the return trip.
So all you have to do
is activate it again
to return to the present.
Right.
And remember,
don't wait too long.
Your body will be experiencing
symptoms
of severe radiation poisoning.
If you don't get treatment,
it will kill you.
I won't forget.
Good.
Julian, there's a...
a message in my quarters
for Keiko if...
I understand, Miles.
0200.
That's three and a half hours
into the future.
Miles, Miles!
Wake up!
What?
Computer, lights.
Oh, no, not you again.
What is it now?
Listen to me.
I've jumped ahead
and seen your future.
Don't ask me how,
it'll take too long to explain.
There's going to be a disaster.
DS9 will be destroyed.
Destroyed? How?
I don't know.
That's why I'm here.
I have to find out
what's going to happen
and then travel back
into the past and prevent it.
You look pretty bad.
It's the radiation.
Well, if you feel bad
and you're my past self
shouldn't I feel bad, too?
I hate temporal mechanics.
Let's get down to Ops
and see what's going on.
Help me up.
Run a sensor sweep
of the entire station.
Look for anything
that might indicate a...
Report!
A Romulan war-bird just
de-cloaked off of Lower Pylon 2.
They've taken out
our shield generators.
On screen.
Lock phasers and return fire.
They've hit the fusion reactor.
Main power's down.
Defense systems off-line.
Try to reroute phasers through
the emergency power couplings.
Miles, you've got your answer.
The quantum singularity
that's been orbiting
the station--
it's the Romulans.
Are you listening?
The Romulans use
a confined singularity
to power their warp core.
That's what we've
been detecting.
That's what's causing
the time shifts.
You must go back and tell them
to put up the shields
and stand by for an attack.
I can't.
I can't get through
another shift.
It's the radiation poisoning,
it...
You go.
Just activate it.
It's set for the return trip.
Me?
I don't belong there.
I'm you... you're me...
It does... doesn't matter.
Just go.
Go!
Chief!
What happened?
It worked.
O'Brien to Sisko.
Go ahead, Chief.
I've been to the future,
Commander.
The quantum singularity
off the station
is actually in the warp core
of a cloaked Romulan war-bird.
They're going to de-cloak and
fire on us in a matter of hours.
Understood, Chief.
Raise shields.
Stand by weapons systems.
I don't understand it.
Your body should be flooded
with delta-series radiation
but there's only a tiny
amount in your tissues.
Your metabolic readings
are different.
What happened?
There's been a... a change.
There's been a... a change.
Uh... I really have
nothing else to say.
I think you're lying, Quark.
About what part?
All of it.
Well, at least I'm consistent.
Quark, you can leave.
Thank you.
I know you have a cloaked
war-bird orbiting the station.
And I know that you're
planning an attack.
At first, I couldn't
understand why
and then I remembered
what you said
about the Dominion--
how they were the greatest
threat to the Alpha Quadrant
in the last century.
If you really believed that
then the only way you
could ever be truly safe
from the Dominion would be
to collapse the wormhole.
But you knew we wouldn't
just sit by
and watch while you did it.
So you had to destroy
the station, too.
That way,
there'd be no witnesses.
Everyone would assume
that Deep Space 9 was destroyed
by what appeared to be
the accidental collapse
of the Wormhole.
An interesting...
theory, Commander.
But that's all it is,
a theory.
That's right.
But I'll tell you
what's not a theory.
We tracked the tetryon emissions
back to your war-bird
and I have about 50 photon
torpedoes locked onto it
right now.
I think it's time we left.
I couldn't agree more.
Constable, will you please
escort our... guests
to the nearest transporter room?
If you'll come with me.
So you're telling me
that you remember
playing this game
with me in the future?
Right.
All right, what am I
going to hit?
20, outer ring.
Why, that's remarkable.
It's also a little disturbing.
I have this nagging feeling
that I don't really belong here.
This isn't really my life.
You know, maybe this life
belongs
to that other Miles O'Brien.
Listen, Chief, whether you
are living in the past
or the present,
you are Miles O'Brien.
The only difference is
you have a few memories
the other one didn't have.
Well, I think I'll go to bed.
I'm still kind of tired.
Now, that sounds
like a good idea.
Quark.
Dabo.
Dabo?
Dabo!
Wait, Chief, wait!
