 PLOT: In the "Pilot", Mulder reveals his sister "disappeared out of  her bed one night... no note, no phone calls, no evidence of  anything" and that, thanks to hypnosis, he recalls "a bright light  and a presence in the room" and that he was "paralyzed, unable to  respond to his sisters calls for help". However, in the "Little  Green Men" episode, she was in the living room with Fox, not in her  bedroom, there was a red light, not white, and he was not paralyzed  at all (he tried to reach for the gun). Also, there was not another  presence in the room, per se.
