"Invasive Procedures" is the 24th episode of the American syndicated science fiction television series Star Trek: Deep Space Nine. It is the fourth episode of the second season.
Set in the 24th century, the series follows the adventures on Deep Space Nine, a space station located near a stable wormhole between the Alpha and Gamma quadrants of the Milky Way Galaxy, near the planet Bajor. This episode explores the Trill species, of which DS9 officer Jadzia Dax is a member: They are formed of a host and a symbiont, with the symbiont passed from host to host as the previous one dies. In this episode, a bitter unjoined Trill attempts to steal the Dax symbiont from Jadzia.[1]
