A leader is found dead in the brotherhood after their "ritual". Now Gus and Shawn has come to investigate and that time they’ve discovered that Henry was a member of that brotherhood and tells Shawn to not to get involve. Next they did was, Shawn is inducted as a member of the lodge. Now Shawn and Gus are able to move about freely and they discover that Holmstrom was being inducted as the Highmost Patriarch of the lodge, skipping the three other people who ranked above him for the spot, including Irving Parker, who, in the wake of Holmstrom’s death, is the new Highmost Patriarch.
Shawn and Gus are visiting all the doctors’ offices from the lodge to compare handwriting. It’s a match. They call Lassiter and Juliet to meet them at the lodge where Shawn explains that Downs killed Holmstrom with a powdered form of the snake venom that he put in the ceremonial hood, the venom being part of an anti-venom that Downs uses in his charitable work abroad. Shawn has solved the case but declares he never would have been able to without Lassiter’s help, putting the detective in the good graces of Parker and the rest of the lodge members, rescinding his blackball status.
