Blue Bloods effectively shut down any chance for a Joe Hill (Will Hochman) spinoff when it concluded his storyline. Introduced at the end of season 10, Joe was revealed as the late Joe Reaganโs son after Sean (Andrew Terraciano) uncovered his existence through a school genealogy project. Joeโs mother had kept his parentage a secret until he became an adult and started asking questions.
Joeโs relationship with the Reagan family was rocky throughout his five-year run. Danny and Jamie struggled to accept him as he was a living reminder of their brotherโs death, while his dynamic with Frank was strained due to Frankโs strict boundaries between his roles as a family patriarch and police commissioner. However, the Blue Bloods series finale saw Joe finally embraced by the Reagans, and he expressed hope for Jamie and Eddieโs baby, calling the child lucky to be part of the family.
With the showโs cancellation for financial reasons, a potential spinoff would have needed a smaller cast. Joe was an ideal candidate to lead such a seriesโconnected enough to the Reagans to maintain continuity, yet independent enough to carry a show without needing the entire family present. However, the resolution of his story ultimately closed the door on this possibility.
