CBS is officially expanding the Blue Bloods universe. The upcoming series Boston Blue, starring Donnie Wahlberg, is set to premiere in fall 2025 and will follow Detective Danny Reagan as he begins a new chapter in the Boston Police Department. After 14 seasons of Blue Bloods, fans were sad to say goodbye in 2024—but with Wahlberg reprising his beloved role, the Reagan legacy is far from over.
While no additional casting details have been confirmed just yet, fans are already speculating about which familiar faces could make their way from New York to Boston. Here are five Blue Bloods characters we’d love to see appear in Boston Blue—whether for cameos, recurring roles, or even major arcs.
1. Maria Baez
Ever since Detective Maria Baez joined the series in Season 3, her partnership with Danny Reagan became a fan-favorite dynamic. Over the years, viewers watched their friendship deepen, hoping for a romantic spark. The Blue Bloods series finale hinted at a possible future between them, with Danny asking Baez out for pizza—but fans were left wanting more.
Having Baez join Danny in Boston would not only give fans the relationship closure they’ve long hoped for but also continue their strong professional partnership. Her presence could bring emotional depth and continuity to the new show.
2. Joe Hill
Joe Hill, introduced in Season 10 as the long-lost son of Joe Reagan, quickly earned his place in the Reagan family. Despite the initial shock of discovering his roots, Joe worked hard to form meaningful bonds—especially with his uncle Danny.
Bringing Joe into Boston Blue would allow that relationship to develop further and offer fresh storytelling opportunities. As a young, driven officer with a complex backstory, Joe could be a compelling addition to Danny’s new world in Boston.
3. Frank Reagan
You can’t talk about the Reagans without mentioning Commissioner Frank Reagan, played by Tom Selleck. His fatherly wisdom and commanding presence grounded Blue Bloods for over a decade. Though he’s based in New York, Frank’s connection to Danny runs deep—and his occasional guidance could play an important role in the spinoff.
According to recent reports, Selleck hasn’t ruled out the possibility of appearing in Boston Blue. After publicly expressing his disappointment about Blue Bloods ending, the door seems open for the beloved patriarch to make at least a few cameo appearances.
4. Jamie Reagan
Jamie Reagan’s bond with Danny was always one of the more heartfelt aspects of Blue Bloods, as the two brothers often leaned on each other both professionally and personally. In the final season, Jamie and his wife, Eddie, revealed they were expecting their first child—an exciting development that fans never got to see play out.
An appearance by Jamie in Boston Blue could serve as a touching family reunion and update fans on his new life as both a cop and a father. Plus, his more level-headed approach would provide a perfect contrast to Danny’s brash, instinct-driven style.
5. Henry Reagan
Henry Reagan, the Reagan family’s wise and witty elder, had some of the most touching moments in Blue Bloods. In the series finale, he offered Danny heartfelt advice about life and love, encouraging him to pursue something deeper with Baez.
Even if he doesn’t make a full trip to Boston, a phone call or video chat with Danny would bring continuity and emotional resonance. Henry’s presence, even from afar, could continue to influence Danny’s choices in this next phase of his life.
Looking Ahead
Boston Blue promises a fresh chapter for one of CBS’s most beloved characters, but its success may also depend on how it honors the show that started it all. Whether through cameos, recurring roles, or heartfelt callbacks, weaving familiar faces into Danny’s new journey could be just what fans need to feel right at home in this new city.
CBS has yet to announce additional cast members, but fans are watching closely—hoping that this spinoff won’t just carry on the Reagan name, but the Reagan heart.
