'X-FILES' KILLS CONFUSING PLOTS By DON KAPLAN NEW YORK POST 12/24/98 THE truth will soon be out there. What fans of the "X-Files" call the hit show's "mythology" - the murky and confusing network of characters like "Smoking Man" and long-running questions like what happened to Agent Mulder's sister - is about to be changed drastically. Sources close to the show say the revision of the "X-Files" deliberately confusing plot line will begin in February with a two-part episode that will tie up loose ends in the show about aliens and government conspiracies. At least two of the show's key players will be killed off, according to the source. "A lot of things will be resolved in this two-parter," the source said. "Way more than the movie promised." Last summer's "X-Files" movie left many fans disappointed because it failed to answer questions about the main characters that have hooked viewers and kept them coming back week after week. Chris Carter, the show's creator, declined to comment on the upcoming changes. The premise of the "X-Files" has been that the show's heroes, FBI agents Fox Mulder and Dana Scully, are against a massive conspiracy to cover up the existence of a hostile alien race that wants to colonize Earth and use humans as living incubators for their young. Some of the highest ranking members of the U.S. government are involved in the cover-up. For several seasons Mulder, a believer in the paranormal, and Scully - a scientist who was originally partnered with Mulder to debunk his work - have pursued various leads to the aliens and their relationship to a close-knit group of powerful government officials who are called The Syndicate. After six seasons of attempting to apply logic and reason to the unexplained, Scully will finally become a "true believer," the source said. "She finally comes to believe everything that Mulder has believed in all along." Other expected revelations include details about a new, rebel alien group called the "faceless alien race." "They literally have no faces," says the source. "And they seem to be helping us, but that just may be because they are trying to thwart the other aliens." Other long awaited revelations include: * The truth about what really happened to Mulder's sister. (From past episodes, we know that Mulder's sister was abducted by aliens when she was a kid and that she has been missing ever since.) * Revealing who the rogue Special Agent Alex Krycek really works for. (Some fans think that Krycek is a Russian agent. He has turned up in several episodes to throw a monkey wrench into more than one of Scully and Mulder's investigations.) Copyright (c) 1998, N.Y.P.
