Message in a Bottle: This was a fun episode, but I can't help but feel disappointed. For a DS9 crossover episode I didn't feel like there was enough connection to DS9.
Where on earth did you get the impression this was a DS9 crossover episode? You said it yourself that no one or nothing from DS9 was in it, that makes it kind of obvious it was not remotely trying to be a crossover with DS9. What made you think it was?
