          DEEP SPACE: "The Adversary" - 04/07/95 - ACT FOUR         33.
                           ACT FOUR                             

	FADE IN:

57   INT. DEFIANT - BRIDGE

	Sisko is addressing Kira, Odo, Eddington and a group of N.D.s.

					SISKO

			Our objective is simple.  Find the 
			changeling and stop him from doing 
			any more damage.
				(a beat)
			We'll break up into two-person teams.  
			Each team will be equipped with phaser 
			rifles.

	Sisko indicates a stack of phaser rifles.

					EDDINGTON
			We've reconfigured the rifles to 
			fire an expanding energy pulse.

					ODO
			The phasers are set low enough to 
			avoid damaging equipment... but high 
			enough to affect the changeling.

					SISKO
			The changeling could be hiding 
			anywhere.  He could look like 
			anything.  So we're going to have to 
			systematically sweep the ship with 
			phaser fire.  Every corridor, every 
			conduit.  If he's out there, we're 
			going to find him.
				(a beat)
			Any questions?

	One of the Security Officers, a BOLIAN, nods.

					BOLIAN
			What if the changeling's not out 
			there?  What if he's one of us?

	Though the Bolian's the one who said it, clearly everyone's 
	been thinking the same thing.  The crewmembers eye each other 
	suspiciously.  They know there's no way to tell the changeling 
	from the person it's imitating.
