In the course of the series, Gerard's family becomes entangled in Gerard's obsession with finding Kimble. In "Nemesis", Kimble unintentionally kidnaps Gerard's young son Philip Junior (played by 12-year-old Kurt Russell). Though as concerned as any father should be, Gerard is confident that Kimble will not do his boy any real harm. After his experience with Kimble, Philip Junior questions whether he is guilty and his father openly admits that he could be wrong, though it does not change his duty. This almost inhuman dedication to his duty strains his relationship with his wife Marie (Barbara Rush) almost to the breaking point and causes her to leave him in season three's two-part episode "Landscape with Running Figures;" her actually coming into contact with Kimble (unknowingly at first) causes an emotional collapse when she realizes who he is, with her screaming at Kimble, "It began with you – it'll END with you!" It is clear that Gerard does indeed love his wife when he finally chooses to go and find her over chasing Kimble. (Gerard admits to Marie, however, that he will go again when the next time comes: "He's stuck in my throat and I can't swallow him.")
