Recap: Star Trek Deep Space Nine S 03 E 04 Equilibrium

Sisko has a dinner party, at which Jadzia plays a tune on a musical instrument, despite insisting that neither she nor any of the Dax symbiont's previous hosts had any musical ability. Shortly afterward she begins having violent mood swings and experiencing strange visions. She, Sisko, and Dr. Bashir go to the Trill homeworld, but their efforts to discover what is happening to her are stymied by the doctors there.

Tropes:

  • Canon Discontinuity: Getting hijacked by Verad apparently doesn't merit as a "Traumatic event" for the Dax Symbiont.
  • Unperson: The Trill government tries to purge all mention of Joran from their records and Dax's memory, causing the problem in the first place.
  • Well-Intentioned Extremist: The Symbiosis Commission have to deceive the public about the percentage of join-worthy Trill to keep the Symbiont species from becoming nothing but a commodity.
