10 Biggest LGBTQIA+ Moments In Star Trek

10. The Trill Do Not Care About Gender-Based Relationships

The Host was the episode of The Next Generation that introduced the audience to the Trill. Though we didn't initially know that they were a joined species, this quickly became apparent once Dr. Crusher's new love interest, Ambassador Odan, was critically injured in an accident. His symbiont was transferred to Commander Riker, and was then subsequently transferred to a female Trill host.

The issue with the final scene in the episode is not that the Trill have a problem with same-sex pairing. If anything, Crusher's dialogue suggests that it is still humanity that is struggling with different variations of romance and relationships. She says that there is still a struggle to see different ways of loving - none of which is reflected in Odan herself.

Here, the Trill are shown as a species to whom the death of the host and a change of gender mean nothing. This would change a little in later descriptions, but for their first appearance, it was both a bold, if muted, statement on how different races viewed love.
