Boston Blue, the spinoff of Blue Bloods, is set to return for its second season in October 2026, promising more character crossovers that fans have eagerly anticipated. Donnie Wahlberg reprises his role as Danny Reagan, who has settled into Boston life following a traumatic event involving his son. Season 1 introduced several Blue Bloods characters, including Marisa Ramirez as Baez and Bridget Moynahan as Erin Reagan, with the latter making two guest appearances. The show's co-showrunners, Brandon Margolis and Brandon Sonnier, have indicated that they wish to invite more Blue Bloods alumni for season 2, with Ramirez confirmed to return. They are actively seeking to bring back familiar faces, which could include notable characters like Frank Reagan, played by Tom Selleck, who has hinted at being open to returning to acting. As the series continues to develop its narrative, the potential for reunions and character interactions remains high, keeping fans excited for the upcoming season.
