no no you guys don't get it. the x files cancer arc was, excuse the pun, a fucking white whale of a tv plotline that would not have worked nearly as well on literally any other show. it was a complete hail mary. the writers' room nearly didn't make it happen because they were worried it would fall too deeply into soap opera territory. and on any other show, it would! but the x files is about four key things: mistrust in the government, faith in both science and the otherworldly, building a life around trauma, and the fine line between love and codependency. it is the only show where the entirety of this situation- a government experiment on an unwilling young catholic leads to a terminal illness that is counteracted by a literal scientific miracle in the eleventh hour due to her partner's refusal to accept her impending death- could both happen at all and happen well. none of the themes in the cancer arc were new to txf at all. they'd all been lurking, to some extent, in the background since the pilot. the cancer arc wasn't merely milking a left-field catastrophe for the drama, it shoved the overarching themes of the show to the front and said look. look what these people are to each other. look how impossible it is to face the darkness alone. regardless of when the plotline was conceived, it was always going to happen. it was the only way the story could have ever gone. they were always doomed from the beginning
