The Bones Fan Theory That Points Fingers At A New Gormogon

The Gormogon investigation is the main arc of Bones season 3, and the team spends the season gathering more and more information about the mysterious, ritualistic nature of the killer's crimes and existence. Before Booth's SWAT team finally confronts the killer and guns him down in his creepy ceremonial chamber, the viewers find out that there have been more than one Gormogon over the years, and that the current one even had an apprentice — Dr. Brennan's youthful assistant Zack Addy (Eric Millegan). The Gormogon's influence looms so large that in season 12, we find out that he also had a second apprentice (James Immekus).  

Though the Gormogon ultimately turns out to be a random person, the show drops several hints that the killer might be a character we've met before we actually see the cannibal in the flesh. In fact, one very major character is suspicious enough that he's even arrested as a Gormogon suspect. The man in question is Dr. Lance Sweets (John Francis Daley), a young psychologist who enters the show as the therapist for both Dr. Brennan and Booth. Though the mental health professional turns out to be innocent and even becomes a series regular, some viewers feel that there's something "off" about the character. What's more, they feel that said something reeks a lot like a hidden career as a version of the Gormogon.
