S4, E8: Booth and Brennan investigate the scene where a body was uncovered during a botched practice police raid. The team identifies the body as a struggling inventor's father who had recently reunited with his son. But when a second body surfaces, the team is led on a trail of deception to find out who was the actual con-man in the inventor's life. Clark Edison returns to the lab, and he and Hodgins work on piecing together blueprints from one of the inventor's potentially valuable inventions. Meanwhile, Booth's younger brother Jared (guest star Brendan Fehr) moves to D.C. to take a job at the Pentagon, and Brennan, smitten with Jared, agrees to go on a date with him to a White House function. Her date with Jared leads her to learn information about Booth's past and give her a far greater understanding into her partner's motives.
