<P> In the episode "Prostrate Before The Law", season five episode 19, Simone is dealing with a suspect who assumes he is Puerto Rican . Simone retorts that he is of French and Portuguese descent and that his parents met in Belize . </P> <P> Early on in his time in the squad Simone started a relationship with Diane Russell, another detective at the 15th Precinct . According to NYPD guidelines the police department did not allow such couplings for officers who worked in the same precinct, so the couple kept it quiet up until the point that they were married by a justice of the peace (Lt Arthur Fancy also knew they were dating, but never officially notified the higher - ups about it). Simone earlier had to convince Diane that she had a drinking problem but was a source of strength and comfort for her as she successfully battled the demons in her past . The couple also conceived a child, but Diane had a miscarriage in season 5 . In that season's finale, Bobby and Diane were married at City Hall . </P> <P> Shortly after the wedding, Simone contracted a critical heart infection that required a heart transplant . Although the transplant was successful and it initially seemed that Bobby would be discharged from hospital, he developed a Gram - positive bacterial infection which soon spread to his brain and other vital organs, causing a quick decline in his health . Due to his being on immunosuppressants at the time to keep his body from rejecting the heart, his immune system was not strong enough to withstand the infection, and he ultimately died, devastating Diane, Andy, and the rest of the team at the 15th . He was succeeded as Andy's partner by Danny Sorenson . </P> <P> Bobby returned, in an episode of the show's final season, as a spirit offering guidance and comfort to a troubled Andy . </P>
