Captain's Log, Stardate 50814.2.
The Defiant is returning to Deep Space 9
after a week-Iong reconnaissance mission
in the Gamma Quadrant.
I can't wait to get home and sleep in my own bed.
The bunks on this ship are so uncomfortable.
You know what I could use?
A weekend at the Golian spa.
Mmm... maybe you and Shakaar can slip away when we get back.
We're not seeing each other anymore.
When did this happen?
No wonder you've been so down lately.
I miss him.
But the last time we were on Bajor
we went to the Kenda shrine and we asked the Prophets
if we were meant to walk the same path.
You make it sound so cut-and-dry.
Well, the way I see it
people are either meant to be together
or they're not.
I guess I'd rather believe
that any relationship can work as long
as both people really want it to.
I'm not sure I have an opinion on the subject.
I need to regenerate.
Is he all right?
You know Odo.
This sort of talk makes him uncomfortable.
I'm trying to cut down.
I'm making Molly
a dollhouse for her birthday.
Oh. Thank you.
The house itself was easy, but the furniture...
even with a microlathe, I'm not sure I'm going
to get it all finished in time.
I guess her dolls are going to have to rough it for a while.
I'm getting some unusual readings
from a nearby solar system.
What kind of readings?
There's some sort of energy barrier
surrounding the fourth planet.
It's hard to tell from the interference
but there could be life-forms on the surface.
If there are, I'd be interested to see how they've adapted
to the quantum fluctuations in the barrier.
Can't we check it out the next time we come this way?
It'll be too late.
At the rate the interference is intensifying
in a few weeks, we won't even be able to send
- a probe through it. - Dax...
I know everyone wants to go home
but if we're going to take a look at this planet
it'll be our only chance.
Are you sure it's safe to pass through the interference?
A few shield modifications, and it should be smooth sailing.
All right, we'll make a quick survey
but if all we detect is some fungus
we're not beaming down.
What if it's smart fungus?
We're approaching the barrier.
All right, old man, take us in.
Adjusting shield harmonics to compensate.
Quantum fluctuations are intensifying.
Are you all right?
I think so.
Dr. Bashir to the Bridge.
No, I'm fine.
The inertial dampers are off-line
and the gyromagnetic stabilizers are depolarized.
We're going to be here for a few days.
Sir, we are being hailed from the surface.
There are several scattered settlements
across the southern peninsula.
I am reading approximately... 8,000 inhabitants.
They appear to be human.
Welcome to Gaia, Captain Sisko.
You know my name?
We've been expecting you.
It's a long story, Benjamin.
Why don't you come down
and we'll talk about it over some raktajino?
Oh, I forgot.
You're trying to cut down.
What a coincidence.
Would one of you mind telling us
what's going on?
This settlement was founded by the crew
of a Starfleet vessel that crashed
on this planet two centuries ago.
I realize this is going to be hard for you to accept
but that ship was the Defiant.
Two days from now, when you leave here
and try to pass through the energy barrier
you will be thrown back in time 200 years.
You'll be stranded here
and become the founders of this settlement.
We... are your descendants.
Go ahead, Jadzia, scan me.
You'll find the Dax symbiont right here.
The symbiont has been passed down
to Jadzia's descendants for three generations.
I remember all of you like it was yesterday.
If you scan Miranda, you'll find that her DNA
is substantially similar to that of the Chief's.
She's an O'Brien, all right.
And a Tannenbaum, too.
You mean Ensign Tannenbaum?
You and Rita were married
ten years after the Defiant crashed.
You were trapped here, Miles, 200 years in the past.
There was no going home.
There was no chance
of ever seeing your family again.
You were the last to give up hope
but, eventually, you had to make a new life for yourself here.
I know that face, Benjamin.
You're still not convinced
that we're telling you the truth.
All right, if you want, I could tell you something
that only Curzon would know.
Do you remember that dancer that you met on Pelios Station?
The one that...?
That... that'll do.
Are you the son of Mogh?
Yes, I am.
Is it true you can kill someone just by looking at them?
Only when I am angry.
Why don't we go inside?
You can meet some of the others later.
We still have a lot to talk about.
Ready for the next problem?
Say you have 27 tessipates
of land you want to plant with nice, juicy yelg melons.
This is our meeting hall, which, as you can see
we sometimes use as a schoolroom.
...needs one square kerripate of land to grow in
what is the total number of melons you can plant?
Let me know as soon as you have an answer.
Jadzia designed it as an educational program.
She took Quark's image
from the security logs of the Defiant.
I've always thought
that Quark would make a great math teacher.
He's so good with numbers.
I like your spots.
Most people don't have them
because our ancestors were mostly human.
My mom says they make me special.
It's just genetics, Lisa, like... Torvin's ridges.
You're just jealous, Molly.
Oh, yes, you'll find a lot of them here.
The name has been passed down through the O'Brien line.
Molly, this is
your grandfather's great-great-great-grandfather.
How much were we...
were you able to salvage from the Defiant?
A portable generator, a replicator
a few phasers, tricorders, things of that sort.
Did anybody ever try to send out a distress signal?
To who? It was 200 years ago.
The wormhole hadn't even been discovered yet.
There was no way back to the Alpha Quadrant.
Our ancestors decided to make this their new home.
And they needed a shelter quickly
before winter came.
This is it.
This is the oldest building there is.
At first, everyone had to sleep here...
all 48 of them.
Kira died a few weeks after the crash.
The energy discharge that struck her on the Bridge
damaged her neural pathways.
The Defiant didn't have the medical equipment
that Julian needed to treat her.
You want to see where she was buried?
Girls, why don't you run along and help your parents?
It's almost time for planting
and there's a lot of work to be done.
- Bye. - Bye.
Obviously, we need to get Kira
back to the station for treatment
as soon as we can repair the Defiant.
I don't quite know how to say this
but now that we know about the accident
that sent the ship back in time, we should be able to avoid it.
Well, if we do that, your timeline will collapse
and everything here will cease to exist.
I have a plan.
And the key is what happened to Kira on the Bridge.
This energy discharge
caused a subspace doubling effect.
For an instant, every molecule in her body
had a corresponding quantum duplicate.
There were literally two Kiras.
If we make certain modifications
to the Defiant's systems
we should be able to amplify this doubling effect
and create a quantum duplicate of the entire ship.
When you encounter the temporal anomaly
the duplicate will be thrown
back into the past, and the original...
you... will pass through the barrier unaffected.
So you're saying we go home
and your timeline is preserved.
What do you think?
It might work.
Now, according to the logs I retrieved from the wreckage
the Defiant encountered the anomaly 39 hours
after it arrived in orbit.
If your plan is to work, we must do the same.
There are almost 8,000 people living on this planet.
This is the only chance they have.
Dax, I want a full evaluation as soon as possible.
If the plan is sound, start making
the modifications immediately.
Thank you, Benjamin.
Anything for you...
Apparently, the planet is crawling with Bashirs.
Maybe I'll stay up here.
He's resting comfortably.
He can't hold his shape
because of the quantum fluctuations inside the barrier.
Sweet dreams, Odo.
But he'll be as right as rain as soon as we leave orbit.
You, on the other hand...
are going to have to undergo
a complete neural pathway induction
as soon as we get back to the station.
If you say so.
I feel fine.
That's because your neural tissue
hasn't begun to deteriorate yet
but rest assured
you'll be on my operating table eventually.
where you off to?
I have to get down there, meet some of those Bashirs.
I came up from the surface as soon as I heard you were here.
How... how are you holding your shape?
I... I thought...
I learned to counter the barrier's effects
a long time ago.
It's good to see you.
You look different.
I've gotten better at shape-shifting
over the years.
You're as beautiful as I remember.
You can't know how I've longed to hear your voice
see your smile.
Odo... what's gotten into you?
There's something I want you to know
something I've wanted to tell you
for 200 years.
I love you, Nerys.
I've always loved you.
What do you mean, you love me?
Is it so hard to believe?
I never knew you felt that way about me.
I did everything I could
to make sure you wouldn't find out.
Why didn't you ever say anything?
I didn't think you could possibly care for me
the way I care for you.
I suppose I was afraid of ruining what we had.
Our friendship meant everything to me.
It still does.
Maybe I shouldn't have said anything.
It's not that.
I was just thinking about all the times
I came to you for advice about Shakaar and Bareil.
It must have been very hard for you
to listen to me go on about another man.
No, I can't say I enjoyed it.
But I wanted to be a good friend to you.
Nerys, I didn't come here expecting you
to throw yourself into my arms.
But you're leaving here in two days.
I'm never going to see you again.
All I'm asking
is that you spend some time with me.
Gaia is a very beautiful place.
I'd love to show it to you.
I'd like that.
He has your eyes.
Do you think so? You think so?
Dax to Sisko.
Good news, Benjamin.
I've gone over the sensor logs from the crash.
It looks like Yedrin's plan
to create a duplicate Defiant is going to work.
Di-di-did you hear that?
Yes, everything's going to be all right.
Sounds like you have your hands full
down there, Benjamin.
Yes, you could say that.
We'll keep you posted.
The Captain asked me to make a survey
of the settlement's infrastructure
so we can leave behind the appropriate supplies.
I've just been doing the same thing at the clinic.
I met one of my descendants there...
my great-great-great- great-granddaughter.
She made quite a fuss over me.
Apparently, my healing touch
is something of a legend around here.
They're here! They're here!
We are the Sons of Mogh.
You are my descendants.
Some by blood, some by choice.
Our hearts are Klingon.
We live as warriors
just as you taught our ancestors long ago.
I'm going to be one of them someday.
I'll ride a wild torga and go hunting
and only come to the settlement
to trade furs for the things I need.
When you're older, you'll have the chance to prove yourself.
If you are worthy
you can take a Klingon name and live among us.
The Sons of Mogh are gathering to celebrate your return.
It would honor us greatly if you would feast
with us tonight.
I look forward to it.
We'll come for you at nightfall.
Well, it would appear
that I'm not the only legend around here.
Once the emitter array is recalibrated
we can start synchronizing the shield generators.
We're ahead of schedule.
You just reminded me of something.
The summer after the crash
it was so hot, Jadzia cut her hair short.
Worf hated it.
I remember promising to grow it back
in time for the wedding.
We got married?
The next fall.
Benjamin performed the ceremony.
I'll never forget Worf's voice as he said his vows.
It was shaking.
Were we happy together?
He's a good man, Jadzia.
It's just, sometimes...
he's so hard to get along with.
You'll learn to handle him.
Did I mention she was a doctor?
Well, she showed me pictures of the family
going all the way back to me.
You know who I ended up with after the crash?
Yeah, that's what I said.
Apparently, she transferred aboard last week.
But she's gorgeous.
You know what?
I think I'm going to ask her out when we get back.
We obviously got along well here.
So, you and, uh...
I don't want to hear about it, Julian.
I have a wife and kids back home.
Sorry. I didn't mean anything.
You know, I'm going to let you get back on with your work.
Praying over your own grave.
That's got to be a new one.
If the Prophets were listening, they're probably very confused.
Well, I wouldn't blame them.
I've got to tell you, that...
this whole quantum duplicate, two Defiants thing
has me feeling a little strange.
Thanks to Yedrin's plan our timeline is being preserved.
You're going back to the station
for the treatment you need.
I know. It...
it's just that I've always believed
that we're all given one destiny... one path...
and now we're using technology to get around that.
I'm not sure how it makes me feel.
I know exactly how it makes me feel.
You can't know how much it means to me
to know you're going home, Nerys.
No, it won't change anything for me.
I lost you 200 years ago.
But for the other Odo, up on the ship
it changes everything.
He doesn't have to lose you.
makes me feel better.
Does that make any sense?
You've changed so much, Odo.
I don't just mean the way you look.
You used to be so closed off.
I have changed.
And the Odo you know will change, too.
If you're patient with him.
Why don't we head back?
We need to talk.
I was going over the sensor logs from the crash
and I came across something odd.
The quantum fluctuations in the barrier
factored out to zero.
The chances of that must be a billion to one.
What are you getting at?
That Yedrin faked the logs.
Why would he do that?
So we'd think his plan was going to work.
There was never going to be
a duplicate Defiant... just one...
and Yedrin wanted to make sure it went back in time.
So that history would repeat itself.
If I hadn't realized what he had done
we would have ended up stranded here
and Kira would have died.
You betrayed us.
You betrayed me.
You call yourself Yedrin Dax
but I don't recognize you.
Well, now that you know
what are you going to do about it?
What do you think?
Oh, damn it, Ben!
If you don't take the Defiant back in time
the 8,000 people on this planet will cease to exist!
You think I don't care?
Oh, come on, you know me better than that.
What am I supposed to do?
Recreate the accident
and deliberately maroon my crew?
That's what would have happened.
Who's to say that's not what's supposed to happen?
I'm not going to stand here and argue philosophy with you.
I have a duty to protect my people.
Look around you, Benjamin.
Think of the things that you've seen since you got here.
This is what your crew
and their descendants will build
if you let history play itself out.
I'm not saying that it won't be hard at first
but they will have good lives here, happy lives.
What about Kira?
If we don't get her back to the station, she'll die.
Is one life too much to ask if it saves 8,000?
Who are you to decide who lives or dies?
Who are you to make that call?!
I have to make that call
because I'm responsible for what happened here.
Jadzia knows what I'm talking about.
She's the one who insisted
that the Defiant investigate this planet.
You know as well as I do
that you should have been more careful...
you should have seen that the barrier was unstable
when you scanned it.
But I didn't.
I was so bent on making some great discovery
that I missed it.
And because of you, because of me
Kira died and 48 people were stranded here.
You don't know what it was like to live with that.
For years, Benjamin, every time I looked at you
all I could think about was Jake, and how, because of me
he would never see his father again.
Eventually, I had to accept the fact
there was nothing I could do to change things.
I couldn't bring Kira back.
All I could do was look to the future, Benjamin
and make sure that we survived here...
no matter what.
This community... is my responsibility.
For two centuries, I have watched it grow
into something to be proud of.
For generations, these people have worked
to make a life for themselves here.
They deserve a chance to hang on to it.
I'm not denying that!
I wish there was a way we could help you
but my people have the right to return home to their families
and I will not ask Kira to sacrifice her life
for 8,000 people... for eight million!
No one has the right to ask that.
I'm sorry, old man
but there is nothing I can do.
Look at them.
They have no idea what's going to happen.
It is for the best.
They are children.
They would not understand.
I'm not sure I understand.
8,000 people, Worf...
they have to die
because I've got to go back to the station
to be treated for some condition
I can't even tell I have.
That is not the only reason we are going back.
Do not blame yourself, Major.
I'm going up to the ship.
It would have been a good crop this year.
Spring came so early.
is something wrong?
Everyone's so quiet.
It's nothing you need to worry about.
We came to tell you there will be no feast tonight.
This is not a time for celebration.
Tomorrow, we will see the sun rise again...
but no one here will see it set.
There is something I wish to say.
It is... a great honor to know that my legacy
has thrived on your world for so long.
I can see the Klingon heart beats strong here.
You honor us with your words.
We have tried to live as you taught us to.
We've never plowed fields or milked chattel.
We've lived as warriors, hunters.
Last year, I slew a yar-bear three meters tall.
Your mek'leth was my only weapon.
The beast maimed me, and for a time
it seemed I would die from my wounds.
Now I wish I had.
It would have been a warrior's death.
He could have taken his place
among the honored dead in Sto-Vo-Kor.
Perhaps he will yet.
Ceasing to exist because my parents were never born?
That is not a death worthy of Sto-Vo-Kor.
Kill me, Worf.
I have no enemies to fight, no glory to be won.
Give me an honorable death.
Don't make us wait for the end
like farm animals waiting for slaughter.
I will come to you tomorrow...
and do what you ask.
Why did you want to come back here?
I had to see it again, so I could be sure.
Sure about what?
That this is where I belong.
The path the Prophets laid out for me ends here.
Well, not this time, Nerys.
The Captain's taking you back to DS9.
I can't let him do that...
not if it's going to cost 8,000 lives.
No, we have to let history take its course
even if it means I have to die here.
What? Have you lost your mind?
Kira, if we don't go back to the station
you'll die within a few weeks.
There's nothing I can do for you here.
I know that, Julian, I've accepted it.
We've got to take the Defiant back in time.
Otherwise, we're cheating fate.
Yeah, well, I wouldn't mind cheating fate
all the way home to the station.
Neither would I
but if we go home, 8,000 people
are going to cease to exist.
I don't know those people
but I have a wife and kids back home who need me.
Your family will be fine, Miles.
The Prophets will take care of them.
No offense, but I don't believe in your Prophets.
All Major Kira is saying is our families
will survive no matter what we do.
The colonists will not.
If she is willing
to sacrifice her life to save them
I am willing to remain here.
Well, that's easy for you to say.
You hardly ever see your son.
And you are afraid to face your destiny.
Look, we can sit here and argue about destiny
till we're blue in the face
but the bottom line is, nobody has the right
to tell me I can't go home to my family.
I want to go home as much as you do, Chief.
I'm just listening to what everyone has to say.
So we're not actually considering this?
No, we're not.
Major, you've made your position clear.
All right, people, dismissed.
By sunset, this will all be gone.
Taking a last look around?
Whoa, whoa, whoa.
Gabriel, where are you going in such a hurry?
To the fields.
It's time for planting.
Come on, Gabriel.
There isn't much time.
Put some of this on your face.
The sun is strong today.
Planting day has always been important here.
It brings everyone together.
Somehow it feels right to see it through.
Oh, here's one for you.
Molly, take that from the bottom.
The status report you asked for, sir.
The repairs are finished.
The Defiant's ready to leave orbit.
Aren't you going to help?
You don't look busy.
She's an O'Brien, all right.
Better get to it, Chief.
You said there was an enemy for us to fight.
They are attempting to plant their fields
before the sun sets.
Time is their enemy.
We should help them defeat it.
Bring the others.
I have a little girl named Molly, too.
Can I meet her?
By summer, this plant will be taller than you.
After the harvest, I'll help my mother
make gelm bread with it.
We can't do it.
We can't let these people die.
The navigational logs from the original crash...
download them into the ship's autopilot
and it'll match the original trajectory.
That should send the Defiant back
to the right point in time.
I don't know...
how to thank you for what you're doing.
We'd better go, Benjamin.
There isn't much time.
You can't do this.
Please don't make this any harder
than it already is.
You have to go home, Nerys... you have to.
This isn't about me.
This is about the 8,000 people down on that planet
their children and their grandchildren.
What about the children who'll never be born
because the Defiant doesn't return to DS9?
They don't exist yet.
These people do.
Nerys, just tell me one thing.
If you'd known how I felt about you
if I'd said something years ago
do you think things might have been different?
Has everyone had a chance
to record a message to their families?
I've downloaded the recordings into a class-4 probe.
It'll start transmitting a location signal
as soon as it clears the barrier.
Launch the probe, Chief.
Transfer helm control to autopilot.
We are breaking orbit.
Coming around to 42 mark seven.
I'm picking up an unusual temporal signature.
It's the anomaly.
We're headed straight for it.
Ten seconds to impact.
We're veering away from the anomaly.
Try to override the autopilot.
We're clearing the barrier.
Someone changed our flight plan.
It wasn't me.
Scan the surface.
No sign of the settlement...
or the inhabitants.
Whoever changed our flight plan
knew their way around the computer system.
They bypassed our security protocols
without leaving a trace.
It must have been someone from the crew.
Or someone who used to be.
But all he cared about was the settlement.
What could have changed his mind?
Seeing us again.
Perhaps he decided
he couldn't let us go through with it.
Everyone we met...
they never existed.
As long as we remember them... they always will.
There's something you should know.
The other Odo, the one from the planet...
came to Sick Bay before he left the ship.
He linked with me.
Now... I know everything that happened.
The, uh... other day, when I told you
about Shakaar and... me
not seeing each other anymore...
you seemed so uncomfortable.
I had come to accept the fact
that you were involved with someone else.
Then suddenly everything changed.
I don't know what to say.
I'm still trying to sort everything out.
So am I.
I think we both need some time.
There's something else the other Odo wanted you to know.
He was responsible for changing the Defiant's flight plan.
So that you wouldn't have to die.
I can't believe it.
He did it for you, Nerys.
He loved you.
That makes it right?!
I don't know.
He thought so.
I'll see you in the morning.
