I like this episode, it brings up some good things that hadn't been spoken of much at all that season.
Sisko's relationship with Kassidy for example, reminding us It still exists for one thing, also what she's doing, I'm pretty sure she lost her job with the Bajorans when she got caught smuggling.
I also liked that for once they were all working on a non-save-the-galaxy-from-doom mission. It was to save one life.
The whole time transmission thing was a bit silly, but it was a good way to make sure that it wasn't a predicatble "We saved her in the nick of time!" or a "We're just too late by a few minutes"
