	FADE IN:

1    INT. QUARK'S

	We begin with a close angle on a small, iridescent disc in 
	Quark's hand.  He turns it over and over as he talks.

					QUARK (O.S.)
			I am merely a businessman.  It would 
			take an orator with the skills of 
			the late, great Plegg himself, to 
			sing the praises of the late, great 
			Plegg.

	We widen to see that QUARK is in the midst of a sales pitch 
	to a curious fellow Ferengi at the bar.  The disc he is 
	holding is a Ferengi "Memorial Disc." Near him is a 
	ceremonially decorated box full of these discs.  Perhaps 
	there are two or three others gathered to watch this.

					QUARK
				(continuing)
			What Ferengi could resist the honor 
			of owning a small piece of the man 
			who took a computer chip and turned 
			it into the modular holosuite 
			industry... a small piece of the man 
			who brought holographic entertainment 
			to the most remote parts of this 
			quadrant, creating profit centers 
			from societies that could barely 
			afford to feed their own people...

	ODO arrives quietly joining the sales pitch...

					ODO
				(re: the disc)
			How much are you asking?

	Quark reacts, knowing Odo is here to screw up his pitch...

					QUARK
			As I was about to tell my good friend 
			here, a mere three strips of 
			latinum...

        DEEP SPACE: "The Alternate" - REV. 10/28/93 - TEASER         2.

1    CONTINUED:

	The Ferengi hears the price and immediately walks... 
	calling after him...

					QUARK
			And I'd be taking a loss at that 
			price... okay, for you, two strips...
				(sighs, he's lost 
				him, to odo)
			Thank you very much.

					ODO
			Three strips?  That's a fair price 
			for Plegg.

					QUARK
				(reacts)
			I suppose you're interested.

					ODO
			Humanoid death rituals are an interest 
			of mine.

					QUARK
			Death rituals.

					ODO
			Everybody needs a hobby.

					QUARK
				(dubious)
			Uh huh...

					ODO
			Some species burn their dead, others 
			pack them in blocks of ice... some 
			even surround themselves with the 
			company of family corpses.  But the 
			Ferengi ritual of chopping up their 
			loved ones and selling them... I 
			find that... irresistible.

					QUARK
				(not buying)
			I'm very busy here.

					ODO
				(pursuing him)
			What a fitting and dignified way to 
			honor the memory of great Ferengi 
			entrepreneurs.  I'm thinking of 
			starting a collection.

           DEEP SPACE: "The Alternate" - 10/27/93 - TEASER           3.

1    CONTINUED:	(2)

					ODO
			Putting up a display case in my 
			office.  There'll be a special space 
			reserved for you in there, Quark.

					QUARK
			I'm sure.

	Odo puts three strips of latinum on the bartop... and that 
	really stops Quark.

					QUARK
			You're serious?

					ODO
			Have you ever known me not to be?

	Quark's waiting for the payoff to the gag... he hesitantly 
	takes the money and begins to slide the disc across the bar 
	to Odo...

					ODO
			Oh, there is one thing I was curious 
			about...

					QUARK
				(knows something's 
				coming)
			And what's that...

					ODO
			How do I know it's Plegg?

					QUARK
			It says so on the label.

					ODO
			Isn't there some sort of letter of 
			authenticity?

					QUARK
				(pointing)
			The Ferengi Seal of Dismemberment is 
			right there.  What more do you want?

					ODO
			I want Plegg.

					QUARK
			You've got him!

        DEEP SPACE: "The Alternate" - REV. 11/12/93 - TEASER         4.

1    CONTINUED:	(3)

					ODO
			Not if he's still alive...

					QUARK
				(a beat)
			Still alive?

					ODO
			Still alive.

					QUARK
				(aghast)
			Plegg?

					ODO
			When I tracked him down on Khosla 
			Two and told him about your little 
			scheme, he was quite amused.  I'm 
			not.

	Odo takes back his latinum strips.

					QUARK
			Odo, I'm a victim here.  I bought 
			these discs in good faith.  I have 
			five thousand pieces of Plegg in my 
			storeroom.

					ODO
			Not Plegg.

					QUARK
			Then who?

					ODO
			Good question.

					QUARK
			I demand an investigation...

					ODO
			You'll get one.  I promise you.

					MORA (O.S.)
			Odo...

	Odo turns to the voice and reacts as he sees...

2    ANGLE

	Doctor MORA POL, standing there, smiling at him.

					ODO
				(surprised)
			Doctor Mora...

        DEEP SPACE: "The Alternate" - REV. 10/28/93 - TEASER         5.

2    CONTINUED:

					MORA
			It's been too long.

	He sticks his hand out and Odo shakes it, definitely 
	uncomfortable... especially with Quark there to observe.

					MORA
			You're looking well.  Yes, coming 
			along nicely.

					ODO
			Why didn't you let me know you were 
			coming?

					MORA
			It was a last minute arrangement.

					ODO
			The trip from Bajor takes five hours.

					QUARK
				(terribly curious)
			Ah, can I get you something... Doctor 
			"Mora" was it?

					MORA
			Yes.  Some Deka tea would be nice...

	Quark goes to work...

					MORA
				(in studying Odo)
			You haven't quite managed the ears, 
			yet, have you?  But, they're 
			difficult.  Is the suit a suit, or 
			part of you?  And what about the 
			boots?

	Quark arrives with tea...

					QUARK
			There we are... nice and hot...

					MORA
			Thank you...

	Quark lingers, Odo waits for him to leave... but Quark can't 
	resist...

        DEEP SPACE: "The Alternate" - REV. 10/28/93 - TEASER         6.

2    CONTINUED:	(2)

					QUARK
			So...
				(beat)
			You two seem to be old friends...

					ODO
				(getting it over with)
			Doctor Mora is the Bajoran scientist 
			who was assigned to me after I was 
			found.

					MORA
				(with pride)
			I was personally responsible for his 
			development during his formative 
			years.

					QUARK
			Then, this is a family reunion!  I 
			had a hunch... well, Odo's dad is 
			always welcome in Quark's... the tea 
			is on the house...

			MORA   				ODO
		Well, actually...			He isn't my...

	But Quark doesn't hear their denials beginning... he blows 
	through it... continuing...

					QUARK
				(to Mora)
			I know he wouldn't tell you himself.  
			But Odo is doing a wonderful job 
			here on the station if I may say 
			so...

					MORA
			Is he...

					QUARK
			Absolutely.  As a matter of fact, 
			when you came in, he was just 
			beginning a fraud investiga...

					ODO
				(interrupting)
			Quark!
				(Quark turns to him)
			Excuse us.

	He pulls Mora away from the bar.

           DEEP SPACE: "The Alternate" - 10/27/93 - TEASER           7.

2    CONTINUED:	(2)

					QUARK
				(calling after them)
			Of course.  You two have a lot of 
			catching up to do.  If there's 
			anything I can help you with, Doctor, 
			don't hesitate to call on me.

	Odo and Mora EXIT.

2A   INT. PROMENADE

	Mora is studying Odo carefully, picks up none of the 
	discomfort that Odo is feeling.  But it is important to note 
	that Mora is extremely likeable in every casual way possible.  
	He has a warm sense of humor, is outgoing with people and 
	even with Odo, he is comfortable in a superficial way.  But 
	there is no intimacy from him toward Odo.  No personal 
	relationship.  More of what you'd expect from a business 
	relationship.  In fact, he is a scientist.   And Odo is his 
	specimen.

					MORA
			That was uncalled for.

					ODO
			You don't know Quark.

					MORA
			I know he was trying very hard to 
			present you in a positive light to 
			someone he thought was important to 
			you and you responded with...

					ODO
				("don't lecture me" 
				implied)
			Please...

					MORA
			Still having trouble with social 
			integration... ?

					ODO
			I integrate as much as I want to.

					MORA
			Define "as much as I want to."

           DEEP SPACE: "The Alternate" - 10/27/93 - TEASER          7A.

2A   CONTINUED:

					ODO
			"As much as I want to" means as much 
			as I want to.
				(already tired of 
				this, a last defense)

			Quark is a thief, a con man, nobody 
			you want to know...

           DEEP SPACE: "The Alternate" - 10/27/93 - TEASER           8.

2A   CONTINUED:	(2)

	Mora studies him, gives a scientific "hmmm"... if we had 
	pipes in this universe, he'd puff on one... They sit at the 
	Replimat.

					MORA
			So how is this police thing you got 
			yourself into working out?

					ODO
			I enjoy my work as chief of security.

					MORA
				(casual, not realizing 
				the pain this causes)
			"Chief of security."  At a weigh 
			station in space.

	As a shape-shifter, Odo probably shrinks a little at hearing 
	this... Mora smiles at him...

					MORA
			Don't you miss it, Odo?

					ODO
			What.

					MORA
			Our work.

					ODO
			Never.

					MORA
			I don't believe it.  I know you too 
			well.  You were unhappy in the lab.  
			I couldn't blame you for that.  But 
			the work, Odo.  The exploration of 
			you.  What you are.  Where you came 
			from.  That's never far from your 
			mind, is it.  Tell me the truth.

					ODO
			That part of it... is true.

					MORA
			Good.  Because I came here counting 
			on that.

	Off Odo's curious expression...

									FADE OUT.

3    INT. SISKO'S QUARTERS

	SISKO is working at his computer as JAKE starts to exit...

					JAKE
			See you later, Dad...

	It takes Sisko a beat to react...

					SISKO
			Hey... hey... hold on...

					JAKE
			I'm late...

					SISKO
			For what?

					JAKE
			For Nog.

					SISKO
			Your homework...

					JAKE
			It's done...

					SISKO
			You've studied that whole Klingon 
			opera for your music test Friday?...

					JAKE
			I'm gonna ace the test, Dad, I 
			promise...

					SISKO
			That isn't what I asked...

					JAKE
			It's not until Friday...

					SISKO
			This isn't about tests, Jake.  This 
			is about learning.

        DEEP SPACE: "The Alternate" - REV. 10/28/93 - ACT ONE       10.

3    CONTINUED:

					SISKO
			You can't learn to appreciate Klingon 
			opera by just cramming the night 
			before an exam.

					JAKE
			I'm never gonna learn to appreciate 
			Klingon opera.  It's a waste of time.

					SISKO
			Being with Nog is not a waste of 
			time but Klingon opera is?

					JAKE
			Yeah!
				(beat)
			What am I ever going to use Klingon 
			opera for?

					SISKO
			First of all, you don't know what 
			you'll be when you grow up... you 
			may discover along the way you want 
			to be a musician or you may wind up 
			around Klingons in some job 
			somewhere...

					JAKE
			Dad, even if I do, they won't be 
			going around singing operas...

					SISKO
			It helps to understand their 
			culture...

					JAKE
			When was the last time you listened 
			to a Klingon opera?

					SISKO
				(beat, knowing that 
				he's getting sucked 
				in)
			When I was your age.

					JAKE
			There, you see?

					SISKO
			Yes.  Do you?

          DEEP SPACE: "The Alternate" - 10/27/93 - ACT ONE          11.

3    CONTINUED:	(2)

					JAKE
			Dad, just because you had to suffer 
			through all that doesn't mean I have 
			to.

					SISKO
				(smiles)
			Yes.  It does.

	A chime at the door...

					SISKO
			Come in...

	Odo is at the door as it opens...

					JAKE
			Dad...

					SISKO
				(the perfect solution)
			Nog has the same test.  Why don't 
			you invite him over to listen to the 
			Klingon opera together?

	Jake looks at him incredulously, laughs at the impossible 
	notion and walks morosely back to his room.

					SISKO
			Sit down, Odo.

	They sit.

					ODO
			Commander, I'd like to request the 
			use of a runabout.

					SISKO
			Of course.  What's up?

					ODO
			Doctor Mora Pol from the Bajoran 
			Institute of Science asked me to 
			help him secure one from the 
			Federation.

					SISKO
			Why did he come to you?

        DEEP SPACE: "The Alternate" - REV. 10/28/93 - ACT ONE       12.

3    CONTINUED:	(3)

					ODO
			Doctor Mora was the scientist who 
			was assigned to me in my first years 
			here... if he went to the Board of 
			Ministers to request permission to 
			approach you, it would take months.  
			And he's very anxious to investigate 
			something in the Gamma Quadrant.  
			And may I say, Commander, so am I.

					SISKO
			You've got me curious, Constable.  
			Is it a secret?

					ODO
			No, but there isn't much to tell.  
			One of the Bajoran science probes 
			recently scanned a planet about six 
			light years from the wormhole.  It 
			picked up some very unique and 
			familiar DNA patterns.  Patterns 
			very much like my own, Commander.
				(beat)
			Doctor Mora thinks he may have found 
			the origin of my people... of... 
			me...

	Off Sisko's reaction...

4    EXT. SPACE - THE WORMHOLE

	The Federation runabout comes out of it into the Gamma 
	Quadrant... the wormhole closes...

5    INT. RUNABOUT

	DAX is the pilot.  Doctor Mora sits in the co-pilot seat.  
	Odo and a second Bajoran scientist are in the background.  
	We'll get to know this other scientist as DOCTOR WELD RAM.

					MORA
				(to Dax)
			As a scientist yourself, Lieutenant, 
			you can appreciate the difficulty of 
			our dilemma, and the elegance of the 
			solution.  When Odo was first found, 
			no one knew who, or indeed, what we 
			were dealing with.

        DEEP SPACE: "The Alternate" - REV. 10/28/93 - ACT ONE       13.

5    CONTINUED:

					MORA
			A shapeless, viscous mass of fluid, 
			a veritable organic broth.  That was 
			our Odo in the beginning.

					DAX
			When did you realize you were dealing 
			with a sentient lifeform?

					ODO
			He didn't.  I had to teach him that 
			myself.

					MORA
				(laughs)
			That's true.  That's very true.  
			Tell her.

					ODO
			It was a dilemma for me.  I'd never 
			seen anything like these creatures 
			either.

					MORA
			"Seen" isn't really an appropriate 
			description.  He had no eyes per 
			se...

					ODO
			I was only trying to describe it in 
			simple terms...

					MORA
				(ignoring that)
			He had never perceived anything like 
			us before... go on...

					ODO
			And I knew I had to find some way to 
			communicate with them.  So I 
			transformed myself into...

					MORA
				(taking the story 
				away)
			It was remarkable.  I'd been coming 
			into the lab every morning, and every 
			morning Odo was still in his liquid 
			form, resting in a Krokan petri 
			beaker.  Well... one morning, Odo 
			wasn't there.  The beaker was empty, 
			and beside it: an identical beaker 
			that had not been there before.

        DEEP SPACE: "The Alternate" - REV. 10/28/93 - ACT ONE       14.

5    CONTINUED:	(2)

					MORA
			A perfect replica in every way.  It 
			was amazing.
				(a look back at Odo)
			It hasn't been the same since you 
			left, Odo.  Working with you was the 
			most rewarding part of my career.

	Odo doesn't acknowledge.

					DAX
			We're approaching the planet.

	We hear the engines disengage...

					DAX
				(continuing)
			Preparing to enter standard orbit... 
			planet designated L-S-Six.

					WELD
			Initiating scans.

6    EXT. SPACE - THE RUNABOUT (OPTICAL)

	moves into orbit around a planet...

7    INT. RUNABOUT

					DAX
			There's a lot of seismic activity 
			down there... possibly volcanic in 
			origin...

					MORA
			That's consistent with the probe's 
			analysis of the area...

					ODO
			Perhaps that's why the changelings 
			had to leave this world...

					MORA
			"Changelings?"  That's a new one.

					ODO
			I've met people from the Gamma 
			quadrant who've heard stories of a 
			lifeform...

          DEEP SPACE: "The Alternate" - 10/27/93 - ACT ONE          15.

7    CONTINUED:

					MORA
				(laughs, interrupting, 
				victorious)
			And you said you weren't interested 
			in our work anymore...

					ODO
			That's not what I said...

					WELD
			I think I've located the area where 
			the probe identified the trace 
			elements... I'm picking up the same 
			DNA traces... entering coordinates...

					DAX

8    EXT. PLANET SURFACE - AMID THE RUINS (OPTICAL)

	Dax, Mora, Odo and Weld beam to the surface.  There are minor 
	tremors throughout.  Dax and Weld have science cases to 
	collect and preserve specimens.  Mora consults a tricorder.  
	As they move through the ruins, we see Weld taking samples 
	away from the main group... he eventually wanders out of 
	view...

9    WITH ODO AND MORA

	As they move through shattered, stone ruins.  Followed by 
	Dax, they approach the center of the ruins.

10   A CEREMONIAL STELE

	a truncated, white stone pillar standing at the center of 
	the ruins.  There are raised letter shapes in the surface of 
	the pillar.

11   ODO

	As he approaches the stele, studies it with an intensity... 
	could the answer to his mystery be on this artifact... ?  He 
	reaches out, almost reverently, to touch it.

					MORA
			Do the letters mean anything to you?

	Mora and Dax have approached the stele and are near Odo as 
	he studies it.

					ODO
			No.  I don't think so.

					MORA
			Well, judging by its position in the 
			ruins, I think it's fair to say this 
			pillar represented something important 
			to the people who lived here.

					DAX
			Why don't we take it with us... our 
			computer back on the station might 
			be able to decipher the inscription...

	Mora acknowledges.  She begins to set small rods around the 
	stele...

					MORA
			Where's Doctor Weld gone to?  
			Weld?

					WELD (O.S.)
			Over here.

12   WITH WELD

	some distance away as he gathers specimens among the broken 
	stones.  Mora and Odo cross to him.

13   ANGLE DOWN

	As Weld takes a sample of a very strange looking tiny lifeform 
	and puts it in a containment case.

					WELD
			I may have found what we're looking 
			for.

					MORA
			Is it carbon based?

					WELD
				(checking a reading)
			No.  Silicate, but vegetative, and 
			very much alive.

	Odo studies it with a real intensity... Mora glances at him, 
	grins...

					MORA
			Odo Junior, perhaps?

	Odo doesn't acknowledge him.  In the background, WE HEAR the 
	effect of the transport field enhancers ZAPPING into 
	operation...

        DEEP SPACE: "The Alternate" - REV. 11/04/93 - ACT ONE       18.

14   WITH DAX (OPTICAL)

					DAX
			Computer, begin transport.

	The pillar DEMATERIALIZES... and as Dax begins to gather the 
	rods... the others return and there is a low rumbling, then 
	a tremor, small at first, but gathering intensity.  Dax 
	reacts, and this all happens very fast --

					DAX
				(urgent)
			Computer, realign transporter... 
			lock on to our combadges...

					COMPUTER VOICE
			Stand by...

15   AT THE BLUFF

	The ground is shaking more intensely... Mora, Odo and Weld 
	move for shelter... there is a deafening roar.  A sudden 
	jolt and loud cracking noise.  The air is suddenly filled 
	with gas escaping from unseen fissures.

16   OMITTED

17   DAX, MORA, AND WELD (OPTICAL)

	Covered by the dust and gas reel back from it toward the 
	bluff.

					COMPUTER VOICE
			Ready for transport...

	But by now, the three humanoids are severely affected and 
	fall to the ground, coughing and trembling.  The shaking 
	continues.  Mora seems almost paralyzed by the effects of 
	the gas.  Dax is choking as Odo kneels to help her.  Weld is 
	doubled over in a fetal position.  Mora is unconscious and 
	not moving.  Odo hits his combadge...

					ODO
			Computer, energize!

22   INT. SURGERY - LATER

	BASHIR is hard at work stabilizing and checking out his 
	patients, Dax, Doctor Mora, and Doctor Weld, who are all in 
	bunks.  Mora and Weld are unconscious, using respirator masks.  
	Dax is resting, but breathing normally.  Odo is sitting, 
	fully dressed on a bed.  Bashir talks to Sisko as he works...

					BASHIR
			They're stable for now.  Dax is in 
			fair condition, the Bajorans seem to 
			be more seriously affected.  Perhaps 
			they were exposed to more of the 
			gas, or there may be something about 
			Trill physiology... I'm not sure 
			yet...

					SISKO
			And Odo?

					ODO
			I'm fine.

					BASHIR
			The paralyzing action occurred when 
			the gas was taken into the respiratory 
			system.  Since Odo doesn't have a 
			respiratory system as we know it, he 
			apparently wasn't affected at all.

					SISKO
			O'Brien's off-loaded the cargo they 
			brought back.  He's set up everything 
			in the Science Lab.  I understand 
			there are some organic specimens 
			from that planet.  Maybe there's 
			something that can help you figure 
			this out.

					BASHIR
			Good idea.

	During the above, Odo has crossed slowly to Mora's bed...

23   AT MORA'S BED

	Mora is breathing irregularly, and with some difficulty.  
	Odo looks at him a long moment.  His mentor seems very weak 
	and small.

        DEEP SPACE: "The Alternate" - REV. 11/01/93 - ACT TWO       22.

23   CONTINUED:

					ODO
				(without emotion)
			Will he be all right?

					BASHIR
			The molecule appears to have quite

	Odo nods, EXITS.  Sisko follows him.

24   INT. PROMENADE - CONTINUOUS

	As Sisko and Odo walk together.

					SISKO
			I know how you feel, Constable.

					ODO
			Feel?  About what?

					SISKO
			When my father got ill... I remember 
			thinking how small and weak he looked 
			lying there in the bed.  He'd been 
			so strong... independent... to me it 
			always seemed there was nothing he 
			couldn't do.  In the end, I realized 
			that there was nothing he could do.  
			And nothing I could do to help him.

					ODO
			I appreciate your thoughts, Commander.  
			But Doctor Mora is not my father.

	Odo moves off... and as Sisko watches him a beat...

25   INT. SISKO'S QUARTERS

	Sisko, his mind still on the scene with Odo, ENTERS to the 
	sound of a Klingon tenor coming from the speakers... sees 
	Jake sitting at the computer... trying desperately to follow 
	the extensive Klingon dramatic text displayed on the screen... 
	looks up doe-eyed at Sisko as he ENTERS... "Satisfied?" his

	Sisko smiles softly... moves across the room, pulls up a 
	chair and sits next to his son, puts one arm around his 
	shoulder, and points with the other hand to the Klingon 
	symbols along with the song... after a beat, (if it still 
	works in this set-up) Jake puts his head on Sisko's shoulder

28   CONTINUED:

					O'BRIEN
			Whatever it is keeps changing...

	He pulls the sample out of the scope... it's in a new larger 
	container...

					O'BRIEN
			It's multiplied so much, I had to 
			change containers... I'll put it in 
			a level-five security field overnight.  
			I wish Dax were here to take a look

					ODO
			Doctor Bashir thinks she'll be fine...

	O'Brien acknowledges, pleased.  Odo moves to the stele... 
	studies it...

					O'BRIEN
			Have any idea what it is?

					ODO
			I'm hoping it's a key, Mister O'Brien.  
			A key to my past.

	Someone or something has completely trashed the Lab -- tables

					SISKO
			You're suggesting the lifeform itself

					O'BRIEN
			I don't know what did this.

	There's a sound from surgery... Bashir reacts, moves into...

49   INT. SURGERY

	The room is dark and Bashir doesn't turn on the lights as he 
	ENTERS.  Mora and Weld are both in bed asleep.  He looks 
	around doesn't see anything unusual...

50   ANGLE - HIS BACK TO THE VENTILATION SHAFT

					(OPTICAL)
			as he wonders to himself what the 
			noise might have been, we see a vague 
			figure drop silently from the ceiling 
			behind him... Bashir doesn't react...

50A  ANGLE - NEAR MORA'S BED

	as Bashir relaxes, takes the opportunity to check the medical 
	monitors... and this all happens extraordinarily fast -- 
	suddenly a tentacle wraps around his neck from behind like a 
	whip and pulls him...

50B  ANGLE

	as Bashir is pulled down sharply by the unseen creature... 
	crashing into a medical supply table... which falls over...

50C  MORA'S EYES

	open... reacting to the noise... just getting his bearings...

50D  BASHIR

	struggling to breathe... reaches out...

51   FAVORING HIS POV (OPTICAL)

	The barest movement of something disappearing into the

52   BASHIR

	out of breath and frightened, as he hits his combadge.

			Emergency!  Emergency!  Intruder

	FADE IN:

53   INT. SURGERY

	A lot of activity.  A Starfleet engineer and a science officer 
	examine the area.  O'Brien is up on a ladder shining a palm 
	beacon into the open ventilator shaft.  Dax is using a 
	tricorder to pick up any organic traces on the floor in the 
	lab.  Bashir is seated nearby.  Doctor Mora is dressed now, 
	stands with Odo and Sisko talking to the shaken Bashir.  
	Weld is still unconscious in bed.

					BASHIR
			It happened so quickly.  I'm sorry I 
			can't tell you more about it.  It 
			was behind me, then it was gone.  
			But it was big.  Very big.

					SISKO
			How badly did you injure it?

					BASHIR
			I don't know.  I don't know if I 
			injured it at all.  I just hit it 
			once with a laser scalpel on its 
			arm, or leg, or tentacle... whatever 
			it was, and it moved up the wall 
			and... was gone.

					MORA
				(with scientific 
				distance)
			It appears our lifeform has survived 
			and grown into something interesting.

					ODO
			Did you notice anything else about 
			the room when you entered, Doctor... 
			anything out of place, anything 
			unusual...
				(Bashir shakes his 
				head, doesn't think 
				so)
			Was it unusually warm, perhaps?

	Mora observes Odo at work...

					BASHIR
				(beat, thinking)
			Now that you mention it, it was a 
			bit warm in here...

       DEEP SPACE: "The Alternate" - REV. 11/01/93 - ACT FOUR       38.

53   CONTINUED:

					ODO
				(to Sisko)
			Another thermal distortion... Did 
			you try the lights, Doctor?

					BASHIR
			No, I didn't want to disturb the 
			patients.

					ODO
			Commander, I suggest we check the R-
			F energy flow to the Infirmary... we 
			might find a power interruption just 
			as we did in the lab.

	Sisko acknowledges.  Mora is extremely impressed with Odo's 
	line of investigation here... Dax crosses to them, checking 
	her sensor.

					DAX
			No blood, or any fluid traces.  But 
			I am picking up a very slight trail 
			of something we didn't see last time.  
			An organic residue.

					SISKO
			Enough to test?

					DAX
			We'll see.

	She EXITS.

					SISKO
				(hits combadge)
			Sisko to Ops.KIRA'S COM VOICE Go 
			ahead.

					SISKO
			Restrict all nonessential personnel 
			to their quarters and go to red alert, 
			Major.

					KIRA'S COM VOICE
			Understood.

					SISKO
				(to Odo)
			Keep in touch with Dax's progress... 
			she might give us a way to track 
			this thing...

       DEEP SPACE: "The Alternate" - REV. 11/01/93 - ACT FOUR      38A.

53   CONTINUED:	(2)

					ODO
			Until we can, I suggest we close 
			down the Promenade.

					SISKO
				(acknowledges)
			I'll give the order, Constable.

	He EXITS... leaving Mora and Odo together.  Mora is still 
	studying Odo with admiration.

					MORA
			"Constable."

					ODO
			It's a nickname that I barely 
			tolerate.

       DEEP SPACE: "The Alternate" - REV. 10/28/93 - ACT FOUR       39.

53   CONTINUED:	(2)

					MORA
			It's the expression of affection 
			that you find uncomfortable.

	Odo bristles at being analyzed even if it is accurate... 
	EXITS... Mora notices his reaction, didn't mean to hurt him, 
	follows with the intention of "making up"...

54   INT. PROMENADE

	As they come out of the Infirmary...

					MORA
			You know, that was really a remarkable 
			display back there...

					ODO
			Display?

					MORA
			You were careful, attentive...

					ODO
			I was just doing my job.

					MORA
			Yes, well, I'm beginning to think 
			that the scientific method and the 
			police method have a lot in common.

					ODO
			I never thought of it that way.  
			Perhaps they do.

					MORA
			In science we look for the obvious.  
			We track in straight lines.  If 
			something looks too good to be true, 
			it probably isn't true.  If there 
			seems to be more to something than 
			meets the eye, there usually is 
			more.  We take it step by step.

					ODO
			That would apply to criminal 
			investigation also.

       DEEP SPACE: "The Alternate" - REV. 11/01/93 - ACT FOUR       40.

54   CONTINUED:

					MORA
			You do it very well.
				(beat)
			I'm proud of you, Odo.  Did you know 
			that?

	Odo just nods, but it's clear that he didn't know that.  
	They walk a beat in silence...

55   INT. SCIENCE LAB (VPB)

	As they ENTER... Dax is examining the traces... checking the 
	monitor... entering instructions, pressing panels... Mora 
	stops to study the pillar, which has been moved...

					ODO
			Anything?

					DAX
				(shakes her head)
			The computer's having trouble breaking 
			down the DNA chains.

					MORA
			What about the pillar... has the 
			computer had any success decoding 
			the encryption?

					DAX
			No luck there either.  All things 
			considered, the computer's having a 
			bad week.  We have such a limited 
			database for the Gamma Quadrant...

					ODO
			I have to shut down the Promenade... 
			call me when you have something...

	She nods... Odo starts to leave... pauses as he looks again 
	at the stele, a thought... to Dax --

					ODO
			Wasn't that pillar over there before?

       DEEP SPACE: "The Alternate" - REV. 10/28/93 - ACT FOUR       41.

55   CONTINUED:

					DAX
				(without looking up 
				from her work)
			I had to have it moved.  It was in 
			my way.

	Odo nods, EXITS...

					MORA
			Have you compared this new organic 
			sample to the lifeform we brought 
			back from the planet... ?

					DAX
			Only enough to be sure that it's not 
			the same...

					MORA
			It might be interesting to see if 
			there are any commonalties at all.

					DAX
				(nods)
			Let me run a cross-tabulation 
			analysis... it should only take a 
			couple of minutes...

	As she enters the information in the computer... Mora smiles 
	to himself, shares the thought --

					MORA
			Do you know Odo well, Lieutenant?

					DAX
			Not as well as I'd like to.  He... 
			keeps to himself a lot.

					MORA
			I'm not surprised.
				(beat)
			I didn't realize... until I actually 
			saw him...
				(a private laugh)
			... how much I missed him... we didn't 
			part on very good terms...

					DAX
			So I've heard.

       DEEP SPACE: "The Alternate" - REV. 11/04/93 - ACT FOUR       52.

55   CONTINUED:	(2)

					MORA
			I didn't want him to leave.  We still 
			had so much work to do...
				(not entirely convinced 
				of what he's saying)
			But I see him now and I wonder if he 
			wasn't right to go after all... he's 
			come such a long way...

					DAX
			He's an invaluable man around here.

					MORA
			I never thought he could do it.  
			Integrate successfully.  If you could 
			have seen him back then, how ill-
			prepared he was to be on his own...
				(beat)
			I was so sure he'd come back.  When 
			he left, I told him he'd come back... 
			And all these years, I was still 
			certain that eventually, he'd show 
			up one day at the lab...
				(beat, a loss)
			I guess I'd better get used to the 
			idea that he's not going to.

56   ANGLE (VPB)

	Parallel monitors flash up two studies of the two samples... 
	microscopic pictures with lots of data readouts along the 
	side...

					DAX
			Here we are...

	Mora has already seen something... moves to one monitor...

					MORA
			Which one is this?

       DEEP SPACE: "The Alternate" - REV. 10/27/93 - ACT FOUR       43.


56   CONTINUED:

					DAX
			That's the new one from the Infirmary.
				(re: the other monitor)
			This is the lifeform from the 
			planet... but remember it went through 
			several metamorphoses...

					MORA
			No, it's not the same entity... the 
			nucleotide sequences are entirely 
			different...

					DAX
			Some metachromic similarities...

					MORA
			Yes... on the most basic level... it 
			may be a distant cousin at best...

	A quiet beep from the computer signals Dax...

					DAX
			The computer's broken down the DNA 
			chain on the new sample.

	She presses panels and a new Okudagram comes up on the 
	monitor... Mora moves closer to study it... he recognizes 
	it, makes a conscious decision not to tell Dax...

					DAX
			I can run an analysis to see if it 
			matches up with any other lifeform 
			in the computer...

					MORA
			How long will that take?

					DAX
			Two, three hours, maybe.

	Mora nods thoughtfully...

					MORA
			Let me know.

	He EXITS.

       DEEP SPACE: "The Alternate" - REV. 11/01/93 - ACT FOUR       44.

57   INT. SECURITY OFFICE (VPB)

	Odo is making a visual check through of all security camera 
	shots of the station... primarily the Promenade... which is 
	virtually deserted.  Mora ENTERS.

					ODO
			Doctor Weld has regained 
			consciousness.  It looks like he'll 
			be fine.

					MORA
				(preoccupied)
			That's a relief.

	He sits.  Odo reacts to the tension in his voice... his 
	manner.

					ODO
			You don't seem relieved.

					MORA
				(appreciating him 
				anew)
			You can tell that just by observing 
			me, can't you... the tone of my voice, 
			my eyes, my body movements...

					ODO
			Yes.

					MORA
			You are such a remarkable lifeform, 
			Odo.  But there is so much we still 
			don't understand about you.

					ODO
				(impatient with him)
			What are you getting at, Doctor... ?

					MORA
			The computer has broken down the 
			DNA chain of the organic sample we 
			found in the Infirmary.  Dax is 
			running an analysis of it now.  She'll 
			have it identified in a couple of 
			hours.  But I already know what it 
			is.  I've seen it before.  The organic 
			sample... it's from you, Odo.

	On Odo's reaction...

									FADE OUT.

	FADE IN:

58   INT. SECURITY OFFICE

	A few minutes later.  Odo is seated, stunned by the news.  
	Mora is more analytical, making the case that condemns Odo 
	with scientific detachment.  More and more throughout the 
	scene, the pressure builds on Odo... the claustrophobia of 
	the Security Office seems to close in on him...

					MORA
			The destruction in the Science Lab 
			occurred at zero-three hundred hours, 
			five minutes.  Then the attack in 
			the Infirmary occurred at nineteen-
			thirty-five.  Roughly sixteen hours 
			apart.  Is your rejuvenation period 
			still sixteen hours...

					ODO
				(acknowledges)
			I was in my pail during both attacks.

	Mora rises moves around the desk, sits on the desk, subtly 
	taking a power position, just above Odo...

					MORA
			But were you... I don't think so.  
			I think, Odo, that you have been in 
			the rather ironic position of trying 
			to track down... yourself.

					ODO
				(a beat, softly)
			How could this be?

					MORA
			Has anything like this happened 
			before?

					ODO
			Of course not.

					MORA
			Are you certain?

					ODO
			Of course, I'm certain.  There would 
			have been incidents.

       DEEP SPACE: "The Alternate" - REV. 10/28/93 - ACT FIVE       46.

58   CONTINUED:

					MORA
			No unsolved crimes on the books?

					ODO
			There are always unsolved crimes.

					MORA
			Then, the possibility exists...

					ODO
				(desperate)
			It doesn't.  I do not commit 
			criminal acts.  It is not in my 
			nature.

					MORA
				(the evidence before 
				us)
			Isn't it?

					ODO
				(a beat)
			The gas.  Maybe it was the gas on 
			the planet.  It must have affected 
			me in some way.

	And Mora has already considered this... it's very likely 
	true... but he doesn't want Odo to be so comfortable with 
	the explanation.  This is his chance.  The chance to get Odo 
	back.

					MORA
			A possibility.

					ODO
			That has to be it.

	Odo rises, about to leave...

					MORA
			It's certainly worth investigating.

					ODO
			Doctor Bashir might be able to...

	Mora stops him with --

					MORA
			Doctor Bashir won't be able to 
			understand anything about this... 
			except that you turned into some 
			kind of out-of-control thing that 
			almost killed him.  Really, Odo.  
			What do you think they'll do with 
			you?

       DEEP SPACE: "The Alternate" - REV. 10/28/93 - ACT FIVE       47.

58   CONTINUED:	(2)

					ODO
			Do?

					MORA
			They won't know what to do.  They'll 
			put you in some kind of high security 
			prison, or quarantine you on a 
			deserted asteroid in the Gamma 
			Quadrant.  Odo, they'll put you in a 
			zoo.

					ODO
			I don't believe that.  You don't 
			know them...

					MORA
			What other humanoid have you ever 
			been able to trust except me?

					ODO
			What makes you think I trust you...

					MORA
				(intense)
			I resent that.  I really do.  After 
			the time I invested in you.  The 
			education I gave you.  The attention 
			I gave you.  You wouldn't be here 
			today without my guidance.  I gave 
			you more than anyone else in my life.  
			You were my life.  And you walked 
			away.  Now, you don't trust me?  
			Fine, put yourself in their hands 
			then.  Always had to learn your 
			lessons the hard way, didn't you...

	Odo is really feeling it now... getting a little moist, 
	turning his back on Mora, leaning his hands on one of the 
	electronic security consoles...

					ODO
				(conflicted, soft)
			I am not going back to the center 
			with you...

	Now warmer, but zeroing in, give and take "affection" --

					MORA
			Why?  We'll work through this 
			together.  The two of us.

          DEEP SPACE: "The Alternate" - 10/27/93 - ACT FIVE         48.

58   CONTINUED:	(3)

					MORA
			We'll solve it together.  Just as we 
			used to.

	And Odo finally loses it, a fist pounding down on the console 
	top... with a flat ---

					ODO
			No.

	And suddenly the power in the security consoles begin to 
	soak into...

59   ODO'S HANDS (OPTICAL)

	morphing into something hideous as the electricity from the 
	console zaps into him...

60   MORA

	reacts with horror... as the unseen thing forms in front of

			We have a power drain in the life

			The creature you're after is Odo.

			At the very least, it is aware... of

					O'BRIEN
			We could reverse polarity on the

			but that's only a guess.

					SISKO
			Set it up on the Promenade... I want

					KIRA
			How do we get him to come out of the

					O'BRIEN
			Maybe we can use some R-F energy

	The creature hits the field and it comes on, opaque, the 
	creature stretching to get at Mora through it... its monstrous 
	figure shaped by the field...

75   MORA

	looking up from the floor, beginning to get up... in an even, 
	regretful tone of voice --

					MORA
			I've done it to you again, haven't 
			I, Odo.  Made you a prisoner.  Dear 
			God, what have I done.

76   ANGLE (OPTICAL)

	The creature struggles another beat and then exhausted... 
	becomes the figure of Odo again... who then collapses behind 
	the field...

77   SISKO

	reacts, rising from his position... hits the combadge --

       DEEP SPACE: "The Alternate" - REV. 10/28/93 - ACT FIVE       55.

77   CONTINUED:	(2)

					SISKO
			Mister O'Brien, drop the field.

					O'BRIEN'S COM VOICE
			Aye, sir.

78   ODO

	laying wet and exhausted on his back... no memory of what 
	occurred... just panic in his eyes.  Mora is the first one 
	there... Odo stares up at him...

					MORA
			We have a lot to talk about.

	And then Mora puts his arms under Odo's limp body and picks 
	him up like a child... and the crowd that has gathered, parts 
	as Mora carries him across the Promenade toward the 
	Infirmary...

79   EXT. SPACE - DEEP SPACE NINE (OPTICAL)

80   INT. INFIRMARY

	Odo is lying down, stronger... Bashir is checking on readings, 
	looks encouraged... Mora is observing...

					BASHIR
			I'm not going to try to explain 
			exactly what happened to you, Odo... 
			because I haven't the vaguest idea... 
			I can tell you with Doctor Mora's 
			help we've managed to eliminate all 
			traces of the gas from your cellular 
			structure... I'll prescribe rest 
			because it's hard for a doctor to go 
			wrong with that one... but otherwise, 
			there's not much more I can do for 
			you.

					ODO
			Thank you, Doctor.

	Bashir nods, gives the two of them some time alone.  After a 
	beat...

					MORA
			I'm going home.

       DEEP SPACE: "The Alternate" - REV. 10/28/93 - ACT FIVE       56.

80   CONTINUED:

					ODO
			Doctor Mora, I want to be sure you 
			know that I had no idea...

					MORA
			You had to speak in a voice loud 
			enough for me to hear.

					ODO
			I'm... sorry.

					MORA
			I'm sorry it was necessary.
				(beat, hard to say)
			I would like... in a small way... to 
			be a part of your life again... your 
			life on the station.  From time to 
			time, we could talk.  About things 
			that matter to you.  To us.

					ODO
			I'd... like that.

	Mora reaches out in a true intimate way and pats Odo on the 
	hand... Odo grabs his hand and holds it... the two men lock 
	eyes for a long beat... and as Odo smiles gently...

									FADE OUT.
