 As "Pilot" did not open with a quotation, "Gehenna" is the first episode of "Millennium" to do so.The episode's title, Gehenna, is the Hellenised form of the Hebrew Gehinnom, the "Valley of the Son of Hinnom".Gehinnom was a location referred to in the Hebrew Bible where children were sacrificed by burning to the Canaanite god Moloch; this ritual sacrifice echoes the cremation of the victims in the episode.
