List of Person of Interest characters

This is a list of characters in the American science fiction crime drama television series Person of Interest.

John Reese (played by Jim Caviezel) is the name adopted by the former United States Special Forces operator and Central Intelligence Agency (CIA) officer who serves as Finch's armed-force used to stop future crimes. Presumed dead following a failed CIA operation in China, Reese's real name is unknown. He was nicknamed "The Man in the Suit" by law enforcement, who know him only in terms of the description given by witnesses.

Harold Finch (played by Michael Emerson) is a reclusive billionaire software engineer who built a machine that predicts future crimes and outputs either the victim's or perpetrator's Social Security number. He is known by a series of bird-themed aliases such as Harold Wren, Harold Crow, and Harold Swift. Finch is very secretive and highly conscious of digital security, and has successfully erased his own digital footprint. A frequent companion of Finch is a dog named Bear (played by Graubaer's Boker). Bear is a Belgian Malinois with military training who Reese rescues from Aryan Nationalists, who were using him as an attack dog.

Jocelyn "Joss" Carter (played by Taraji P. Henson) is a detective in the New York City Police Department (NYPD) 8th Precinct Homicide Task Force. She is a single mother of one son, Taylor, whom she is close to. Formerly a United States Army interrogator, she passed the bar examination in 2004, but gave up practicing law to return to police work. Carter crossed paths with homeless John Reese ("Pilot") following his encounter with a group of young men on a New York City subway, but she later reconnects with him as the mysterious man in a suit. Carter is initially determined to apprehend Reese as a person of interest (a person not formally accused of a crime) even after Reese saves her and her son on separate occasions. However, when the CIA tries to assassinate Reese without due process, she gradually revises her views and starts helping Reese and Finch instead.
