Josef Kobold: Agent Reyes believes me, but you don't, Mr. Doggett.
John Doggett: Doesn't matter what I believe.

John Doggett: You been checking up on me, Professor?
Josef Kobold: Ordinarily men don't pursue occupations against their own inclination, unless there's some strong countervailing reason. Seeking the love or approval of a woman perhaps. Agent Reyes may have affection for you...

Do you believe in the power of the devil?
7 February 2008 | by (Sandy, UT, United States) – See all my reviews

Dæmonicus is one of the few season 9 episodes that I like. I like it a lot actually. Rarely am I faced with an episode in which I can tolerate Reyes' random ramblings and crazy ideas. It is interesting in this episode that Scully seems to join sides with Reyes even if its just because they are both worried about Doggett. Two things make this episode great for me; first is the creepiness factor, and second is Agent Doggett.

I really enjoy the teaser. It is probably one of the scariest teasers I can think of from the entire series. Just to mention a few of the other creepy elements/scenes: the great masks that the possessed men wear, the way the fan stops moving when Reyes touches the wobbling scrabble piece but then starts right back up again when she is snapped out of it, the way the clouds move way too fast while we hear some kind of backwards evil chanting, the forest in general and when they find the guy hanging upside down out there, and finally the puking scene. I love the puking scene. I can't help but be both terrified and amused at the way this scene goes down. First its totally random when the doctor starts puking on Doggett but then he continues and grabs his head and collapses in it as he continues to let forth a continuous stream of green psychic plasma puke.

Leading me to Doggett. I enjoy Doggett's struggle in this episode. He is asked the question, "do you believe in the power of the devil?" Doggett responds by saying that in effect he doesn't actually believe in the devil at all and that it is all a story made up to scare people; however, as we continue to watch Doggett sees more and more evidence of evil. He is coming to the point where he can't really deny the presence of evil and because of this he becomes extremely defensive and zealous about making sure that he disbelieve anything anyone suggests about the matter. Scully and Reyes even confront him on it. At the end it appears that Doggett has found a solution that disproves any presence of evil throughout the case but as Reyes says in response to Scully's question about what one thing Doggett was afraid to explain is not that Reyes felt the presence of evil but that he did.

The ending of the episode is perhaps the only thing that doesn't sit well. The explanation that Doggett comes up with in the word Dæmonicus may make sense to Reyes but when did anything that made sense to Reyes ever make sense to anyone else? I thought it was an extremely far fetched explanation and had too many holes. Then again this may just be a way of saying that Doggett was so afraid to explain the presence of evil that he was willing to accept any other explanation at all no matter how far fetched as long as it didn't involve the devil. The true answer to "do you believe in the power of the devil?" should be only in as much power as we give him. I give the episode a 10 out of 10.
