The Search, Part I

After deciding not to make T'Rul a recurring character (see below), the producers also decided not to use the cloaking device beyond "The Search, Part I". Indeed, they actually planned to mention early in the season that the cloak had been returned to the Romulans. So certain were they that it wouldn't be used again that they even informed production designer Herman F. Zimmerman and director of photography Jonathan West, and told them that they didn't need to design an elaborate lighting rig because the dimming effect seen when the ship is under cloak would only ever be seen once. As such, Zimmerman's set design didn't allow room for West to construct a rig which could contain the set-up necessary for both normal lighting and cloaked lighting. Instead, West had his crew simply manually change the lights for the scenes under cloak. Of course, only a few episodes later, in Defiant (1994), the cloak was once again employed, and many times after that, but the set and the lighting rig were never redesigned, so every time the ship went under cloak, West had to have his crew manually change all of the lights, something which he was quite annoyed about.

As soon as Odo got to the bridge, the Jem'Hadar should have halted their attack, since they revered the Founders as deities and wouldn't dare harm one.
