I really liked Rejoined, probably Jadzia's Dax's strongest episode (which, I know, isn't saying much). Though one has to notice that this is now the second time Jadzia is willing to throw away the life of the symbiont cause she's in love. This seems odd for someone who essentially worked harder than any other joined Trill to get a symbiont in the first place.
There is one aspect to this episode that bugs me, though technically it's a problem I have with S7's "Afterimage" and not so much this one. Here, Sisko tells Jadzia to take some vacation time while Lenara is on the station just so she doesn't tempt herself and end up in a compromising situation with someone she hasn't been married to in decades. Fast-forward three years and Sisko's asking Ezri to come and live on DS9 where she can work closely with the man she was married to just months before on a daily basis. Worf even mentions reassociation to Ezri after they have their fun and she just blows it off like it's no big deal.
