Equilibrium, DS9 3
Although I generally find further inquiry into the mechanics of the Trill race fascinating, this episode takes as many of its cues from the odd episode of Scooby Doo than anything else. The upshot is that the Dax Symbiote was hosted, for a brief spell, by someone that Jadzia (and the other Daxes) didn’t know about. Indeed, these few months have been blocked from her memory, lest a horrible secret be learned. Of course, the system that is blocking the memory (a drug?) is wearing down, causing Jadzia to go all goofy. Sisko & co. learn this – it ain’t as hard to be a Trill host as you might think. But keep that on the d.l., lest there be a panic in the streets. In exchange for Jadzia’s life, they agree – something Picard would probably not have done. (Not that he would have let Jadzia die, he just would have moralized for so long that the Trills would have relented.)
I make this episode sound better than it is. It is mostly bad Terry Farrell acting.
