Joseph Hill, played by Will Hochman, is a character on the TV show Blue Bloods. He is a late addition to the show and doesn't play a major role in the main storyline. He is the son of the late eldest Reagan child and serves as a reminder of his father. There is speculation about whether Joe Hill will be returning for season 14, as there have been no official casting announcements from CBS. A petition has been started to bring the character back, but its origins are unclear.
