Destiny

While in full Cardassian makeup, actress Tracy Scoggins (Gilora Rejal) took the opportunity to walk around the Paramount lot, "scaring schoolchildren on buses" before security called the DS9 set, saying, "Could y'all do something about keeping your aliens contained over there?"

The crew of the Defiant observe a comet near to the gamma quadrant exit to the worm hole. The comet has a tail - comets only develop tails as they approach a star. The star heats up the comet, which produces a tail of water vapor which always points away from the star. In addition, the speed of stellar objects like comets are such that ships would've detected it on their sensors months or years prior the episode, and would've known that the comet would've come close to the wormhole.
