Theef

Dr. Wieder:  Agent, you're a doctor.  Explain to your partner that no one can "direct" a person to get sick. Mulder:  The dirt you found in your bed drawn in the shape of a body.  That's indicative of folk magic.  That's what I believe is being used against you. Dr. Wieder:  Folk magic.  You mean like Baba Yaga... Gypsies. Mulder:  I was actually thinking less Eastern and more Celtic. [Scully looks at him.] Mulder:  Maybe... Scots-Irish or Appalachian, even. Dr. Wieder:  I'm supposed to take this seriously?

Well if anyone else said it I would say no but since it's Mulder....  After all these years one would think that Mulder would have figured out a way to phrase things so they don't sound quite so psychotic.

General Punkesque Behavior

Sexist!Mulder rears his ugly head:  When talking to Dr. Weider, Mulder asks if his father-in-law had any enemies.  Then he says that if "Theef" doesn't refer to the father-in-law that it must refer to him [Dr. Weider]  Did it occur to Mulder that "Theef" could have referred to the wife?  (I'll admit that it would appear that the wife doesn't; do much of anything but Mulder wouldn't have known that.)

Did Mulder really think that telling Dr. Weider that folk magic is involved in what happened to his family was going to help?  Doctors are notorious for being unbelievably arrogant.  What made Mulder think that Dr. Weider would be open to extreme possibilities.

Forgetting that Mr. Peattie beat him to the punch, how exactly did Mulder make the jump that it was the daughter's body that was being used as a charm.  The cultist said it could be anything and graveyard dirt can be found at any neighborhood cemetery.  The leap of logic from charm to daughter's body doesn't make a lot of sense.
