Jadzia Dax - Death

Death

Jadzia is killed in "Tears of the Prophets", the finale of the sixth season. She and Worf had been trying to conceive, despite the doubts of Dr. Bashir that such a pregnancy was possible. After Major Kira tells Jadzia she has been praying for a conception, Jadzia receives encouraging test results from Julian, and goes to the station's temple to thank the Prophets. It now appears a pregnancy will be possible. The Cardassian Dukat arrives, possessed by a Pah-wraith, with the intention of destroying the orb-like Bajoran artifacts known as the Tears of the Prophets. Jadzia is no match for Dukat while he is infused with the Pah-wraith; he kills Jadzia and destroys the orbs. Upon her death in the infirmary, an agonized Worf screams out a Klingon wail of sorrow for his beloved and to let the Klingon afterworld know a warrior was on the way (Heart of Glory). Her untimely death shakes the crew to its core: by the beginning of season 7, Sisko has left the station in despair, and Worf has been risking his life on increasingly dangerous missions.

Though the host Jadzia is dead, the symbiont Dax survives and is implanted in a Trill named Ezri Tigan. The resulting joined Trill Ezri Dax becomes a main character during the seventh and last season of the series. Several episodes focus on Ezri Dax resolving her relationship with Worf, and the subsequent development of a romantic relationship with Dr. Julian Bashir.
