A man's body in a tub full of lye is hard to identify, except for its brittle bone disease and paternity. However it fits two sets of father and sibling cases: electrician Larry Turner has a daughter with teacher Lila Turner and Lawrence Seaver has a son, Ray, with Gayle Seaver. Apparently both mothers ignored his double life and bigamy. Meanwhile the team wonders about Booth's feelings for his own son Parker's mother, Rebecca Stinson, who rejected his marriage proposal. Chop sticks worn in a woman's hair point to a Chinese restaurant, where the wives met and discovered that "Larry/Lawrence" made a third woman, Chloe Daniels, pregnant, yet the trio claims Larry killed himself. Forensics shows he was shot in the head after dying on the construction site of bitterly dissatisfied customer Pete Valera, thus suspect #4.
