Before joining the 12th precinct as a homicide detective, Esposito served in the Special Forces and was an officer in the Organized Crime Task Force at the 54th precinct. Alongside his partner Detective Ryan, they work tirelessly with Detective Beckett to solve murders and bring killers to justice. Always ready with a sardonic comment, Esposito is a loyal partner and a dedicated cop. Even in the face of adversity, he’s got his game face on and nothing can break him. He may have a bit of a bromance with Ryan but he considers himself quite the ladies man. Despite his constant wise cracks, Esposito is very intuitive and has always recognized the romantic tension between Beckett and Castle.
