There are numerous similarities between this episode and the events that occurred in the famed Salem, Mass. in the colonial era. A group of teen girls began accusing people of witchcraft and the town became so hyped that several people were hung for the crime. Arthur Miller's The Crucible is not historically accurate, but captures the general feeling of that time. His play was an allegory of the McCarthy trials, which showed similar hysteria over a perceived threat. In the tradition of X-Files, of course, there was an actual threat in this episode, not just a preceived one.
