Doctor Beverly Crusher is secretly in love with Federation ambassador Odan, who is on his way to the Alpha Moon which is rebelling against the planet they were colonized from and causes potentially fatal environmental damage to the Beta Moon. Crusher ignores the fact that her humanoid lover's body has an alien symbiont in his entrails, but Counselor Deanna Troi empathically senses emotional swings which set her on the trail. An unrequested escort vessel from the Beta Moon then approaches and attacks the Enterprise shuttle which Commander Will Riker was piloting to take the ambassador to his destination. When Riker brings Odan back to the Enterprise badly wounded, Crusher's diagnosis reveals the 'parasite' and she learns his true identity. Odan urgently needs another humanoid host to perform his peace mission, for which task Riker volunteers. Written by KGF Vissers

Did You Know?


The appearance of the Trill symbiote would change its appearance from when it initially appeared on this episode to how it would appear on Star Trek: Deep Space Nine (1993). In this episode, the symbiote's appearance was made to resemble a caterpillar with the head of an octopus. According to Make-Up Supervisor Michael Westmore, the symbiote was re-made for DS9 to be more "streamlined" to make it easier to handle. Also the appearance of the Trill hosts would change as well. In this episode the Trill hosts had semi-ridged foreheads and no body spots, but on DS9 they have normal foreheads and body spots. See more »


Odan is identified as a Trill, the doctor states that there is not a lot of information on Trill anatomy. This clashes with the 30+ years that Benjamin Sisko is acknowledged as having known Curzon Dax. Surely Starfleet would have more information on the Trill. See more »


Counselor Deanna Troi: It feels good to indulge yourself sometimes.
Doctor Beverly Crusher: I guess so.
Counselor Deanna Troi: Especially when you haven't done so in a while.
Doctor Beverly Crusher: What... What is that supposed to mean?
Counselor Deanna Troi: Beverly - you're in love!
Doctor Beverly Crusher: Sometimes I wish you weren't so... empathic!
Counselor Deanna Troi: [leans over, whispering] I don't think it's really a secret.
Doctor Beverly Crusher: It isn't?
Counselor Deanna Troi: [shakes her head] You've been glowing!
Doctor Beverly Crusher: Oh... Must be the astringent.

Dr. Crusher considers polygamy.
20 November 2014 | by MartinHaferSee all my reviews

When Star Trek fans see this episode today, the mystery isn't so mysterious. After all, one of the cast of "Star Trek: Deep Space 9" was supposed to be of the Trill--so the notion of having a body as a host and a sentient separate being inside isn't surprising. Back when "The Host" debuted, however, this was all new and probably surprised more than a few of the fans. That's because Dr. Crusher has fallen in love with Ambassador Odan and doesn't realize that as a Trill he also has one of these beings living inside. Now this isn't a case of "Invasion of the Body Snatcher"--the relationship is voluntary and both sides benefit from this relationship. However, Dr. Crusher isn't prepared for this and only learns about this bonding when Odan is injured and his host body dies! In a pinch, to keep him alive, the thing known as 'Odan' temporarily is hosted by Riker--an awkward situation for the Doctor, to say the least! How does all this play out---well, see the show to find out for yourself.

This was a great introduction to the Trill and made for a very interesting episode. It also offers some interesting bisexual subtext--something which might surprise some viewers. Well done overall.
