O'Brien is on his way to the planet Parada to warn them about something and is chased by the crew of Deep Space Nine through the wormhole. In his log he tells what happened. Deep Space Nine was supposed to host peace talks between the Paradans and a rebel faction and O'Brien was supposed to make sure the security to be top notch. He immediately noticed something strange when Keiko and Molly didn't seem to be themselves. In engineering, he found out another engineer was ordered by Sisko to already start work on the security measures. Sisko told him to concentrate on the repair of the upper pylons and ordered him to undergo a very extensive medical examination. O'Brien especially got suspicious after he found out he lost his level 1 security clearance after trying to review the logs of the security personnel. Written by Arnoud Tiele (

Jadzia Dax only speaks offscreen in this episode, in O'Brien's playback of vocal station logs. She appears briefly as Bashir ambushes O'Brien in Ops. See more »


During O'Brien's escape he goes through some Jeffries Tubes (the crawl space conduits). At the end of one of the tubes is a flat photograph or painting of more tubing to give the illusion that it continues on for a very long distance. However the picture is reused from Star Trek The Next Generation and matches the design of the USS Enterprise D's Jeffries Tubes rather than the Cardassian-built tubes of Deep Space Nine and therefore doesn't match the rest of the tubing making the transition more obvious.

This episode is reminiscent of the Philip K Dick short story put to film in the late 1990s, "impostor" starring Gary Sinese.

But that film had a gimmick, whereas this episode also uses the exact same gimmick, but that gimmick is not revealed until the very last scene, which gives this episode a more eerie landscape.

All we know here is that Ò'Brien comes back from a mission and everything is just off kilter slightly, enough to raise his alarm level. His daughter won't touch him, neither will his wife. That right there is enough.

Even so, if that had been all that happened this O'Brien might have shrugged it off eventually. But that wasn't the end of it. Miles had been put in charge of high-security preparations for an upcoming visit by some Gamma quadrant dignitaries, "The Paraden". When The Sisko pulls him off of that detail and orders him to do basically a "clean the toilets" job on Deep Space 9, that's when Miles calls all bets off.

This episode shows why Miles Edward O'Brien is just as good an engineer on Deep Space Nine as Geordie Laforge was on the Enterprise D or Scotty was on the original "Enterprise" (NX-01 does not count).

When it seems like the entire Ops crew of Deep Space 9 is about to cave in on Miles, he widgets his way out of a tough situation and escapes to the Gamma quadrant.

But why go to the Paraden home world? Why? What is there that is so damned important?

Look for Leonard Nimoy's wife as the Admiral O'Brien speaks to on his way out, seen earlier in the episode "past prologue."

The main premise of this episode is extremely similar to the main premise of the Gary Sinese character from "impostor", in fact the same thing is happening to O'Brien here that happened to the character in "impostor."

I think a lot of the reviews I have been reading lately that have just been popping up in the last year especially, are completely missing the point of Deep Space 9. Deep Space 9 was not an episodic television show. No- it was one story from start to finish. That is how I watch it, and that is how I rate it. Not one episode is more important or less important than any other episode, because the storyline is entwined into every single episode. If you miss one episode, or dismiss casually one episode, then you will definitely miss something very important that will come up later in the series. Because a lot of the small details from the so-called "filler" episodes may come back in a later episode. And because I can honestly say that I enjoy All of this epic tale.
