Everything is perfect in this episode. The story is scary, just like the character. Mulder and Scully's relationship is interesting because they do not feel the same way. The game of DD, as every time Scully is in danger, is at its best. The mental delirium translated by psychic photo is a great idea, even if it seems unlikely for real ... But it's x files! And what a suspense !! For me the best loner of season 4.
a 9/10 deserved.
