A Master Mason tracing board, found in the season opener, The Widow's Son in the Windshield, is seen again in the evidence lock-up during the season final episode. [00:10:30]
Hodgins, since season one, has been a promoter of various conspiracy theories:
Sweets: "Why would there be a conspiracy in this case?"
Hodgins: "Prominent public figures being murdered, and eaten. Evidence that secret societies are being targeted. Societies that have great influence in the halls of power like, the bureau." [00:15:30]
Brennan, in an attempt to extract information from Zack, plays to his paranoia:
Brennan: "Assumption number one: secret societies exist."
Zack: "Accepted. Hodgins has been explaining this to me for years."
Brennan: "Assumption number two: the human experience is adversely affected by secret societies."
Brennan: "Assumption number three: attacking and killing members of secret societies will have an ameliorating affect on the human experience." [00:35:30]
None of the victims were ever identified as freemasons one being a US senator, one a Catholic bishop and another being a member of the Knights of Columbus, and the many others remaining unidentified and it was never clearly explained if the Gormogons were an actual group or simply an individual who passed on his fixation to a successor through many generations.
Many long-time viewers of the series expressed their dissatisfaction with the resolution of this story (see imdb.com), the killer being identified as "a nobody" and his apprentice being discovered to be one of the forensics team.
