The second season begins with Barron and Chartier responding to reports of a snake at a daycare centre. Chartier encounters an armed civilian: Barron's cousin Cassie Clemont. Barron's unsavoury relationship with Clemont makes Barron the prime suspect of the SQ's investigation into the mole in 19. When Chartier brings Barron into the investigation, Barron and Clemont burgle a suspect's house and make a rash decision that endangers both of them.
