Prologue

When Mulder and Scully go looking in a rundown, abandoned apartment for something of extraterrestrial origin, they end up switching bodies. They now must figure out how to switch back, all the while making sure no one figures out what has happened to them. Will Mulder and Scully switch back?
*Please note* This takes place in between episode 18 and 19 in season 1.
*Please note as well* I do not own Mulder or Scully or the X-Files(otherwise this episode would have totally happened)
