A Millennium character profile, listing all episodes and seasons in which Mary appeared. The main characters of Chris Carter's Millennium have summaries and biographies where available. Where possible and relevant, we've also included any determined allegiance to for example Millennium Group Factions such as Owls and Roosters or if the person is determined as being a member of Legion etc.

Please note that our episode, cast, character and crew profiles may contain potential spoilers if you have yet to see the entire series of Millennium.
