Months after the investigation of Mary's kidnapping, and the FBI's unsuccessful raid seeking methamphetamine at Mary's house, the FBI arrests Brandi on drug charges stemming from that investigation. Wondering where the FBI got new information to bring the charges, Mary asks Stan's help to sweep her house for bugs, and they discover a device planted in one of the walls. Mary learns that the young woman who recently came to visit Jinx might be her half-sister - but suspects that that woman might actually have been part of an FBI ruse.
