We've established that the government can't be trusted, science can't be trusted, and personal beliefs can't be trusted. But the Amish, those technology-shunning, hardworking, nice people, can be trusted, right? Well, no. The line trust no one applies to everyone, Amish included.
Mulder and Scully investigate several deaths occurring after copulation, leading them to the "Kindred," an Amish-like community. As the title, "Gender Bender," suggests, these people changes genders and that's probably the most interesting part of the episode.
The episode implies that the Kindred may be extraterrestrial. They refer to people as humans and say "your world." At the end of the episode, all they, along with their underground cavern, are gone and a crop circle is left in the ground. It's never made clear exactly what their motivations are. In this case, their abilities alone aren't enough to carry the episode without a better idea of what they want.
Score: 8.6/10
