'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.
