Enterprise encounters a hyper-giant star. While there, they make first contact with the Vissians, a technologically sophisticated race with three genders. While making quick friends, and eagerly learning about the advanced technology, Trip gets curious about the Vissians third gender, known as the Cogenitor, who is crucial in the Vissian reproductive process. Against the wishes of the Vissians, Trip befriends the Cogenitor and encourages it to defy its cultural boundaries, which the Vissians are made aware of, and are angered by. Written by Meribor

The Vissian chief engineer tells Commander Tucker that a polymer used on their ship is made of more than 200 naturally occurring elements. Tucker is shocked because the Earth database show only 92 naturally occurring elements. What's wrong here is that at the time of filming there were already 94 naturally occurring elements discovered and not 92 (as of 2017 94 plus 24 synthetics elements for a total of 118 ). See more »


[Tucker has interfered with Vissian customs by exposing the cogenitor to Human culture...]
Captain Jonathan Archer: I might have expected something like this from a first-year recruit. But not you. You did exactly what I'd do? If that's true, then I've done a pretty lousy job setting an example around here. You're a senior officer on this ship. You're privy to the moral challenges I've had to face. You know I've wrestled with the fine line between doing what I think is right and interfering with other species. So don't ...

Original, Dramatic and Tragic- The Best Episode of the Second Season
23 January 2008 | by claudio_carvalhoSee all my reviews

While preparing the sensors to observe a hyper-giant that will be transformed in a supernova, the Enterprise makes first contact with the amicable and highly developed Vissians. The race of explorers is invited to visit the Enterprise and the crews exchange information about each civilization. Trip is intrigued about the third gender of the Vissians, necessary for their reproductive process, and Dr. Phlox explains that there are many races with more than two genders and T'Pol asks him to not interfere with the Vissian culture. When Trip finds that the Cogenitor, who does not have a name, is illiterate and treated like and object, has the same level of intelligence of the males and females of its race, he decides to secretly encourage it to learn how to read and expand its culture, tragically affecting the relationship between humans and Vissians.

"Cogenitor" is original, dramatic and tragic, and certainly the best episode of the Second Season up to now. The story is important to show that there are different cultures where the concepts of what seems to be right or wrong are different from the standards of others and must be respected, no matter in deep space or on Earth. In Brazil we have a saying that could be translated as follows: "the hell is full of people with good intentions". Trip seems to have learned the lesson through the most difficult way when he sees the consequences of his action. My vote is ten.

Title (Brazil): "Cogenitor"
