Excitement around Boston Blue continues to grow as Donnie Wahlberg has revealed that another Blue Bloods alum is set to join the upcoming spinoff. The announcement further reinforces the idea that the new series is being built as a true extension of the long-running CBS drama rather than a complete departure from its roots.
Wahlberg, who played Danny Reagan for more than a decade, shared the update while discussing how carefully the creative team is approaching the transition from Blue Bloods to Boston Blue. According to him, bringing familiar faces into the new series is a deliberate choice aimed at preserving continuity and rewarding loyal fans.
While the identity of the returning alum has not yet been officially announced, the confirmation alone has sparked widespread speculation. Viewers are already debating which former cast member might make the move, with names ranging from Reagan family members to fan-favorite supporting characters who left a lasting impression.
This latest reveal follows earlier confirmations that multiple Blue Bloods veterans will guest-star during Boston Blue’s first season. Taken together, the casting strategy suggests that the spinoff will rely on emotional connections as much as new storytelling, easing audiences into a different setting without abandoning what made the original series resonate.
Wahlberg has emphasized that these appearances are not meant to overshadow the new cast, but rather to help anchor the show’s tone and values. The goal, he explained, is to create a series that feels familiar yet forward-looking, allowing Boston Blue to stand on its own while still honoring its lineage.
Fan reaction to the news has been overwhelmingly positive. Many viewers see the returning alumni as a sign of respect for the original show and its characters, particularly after Blue Bloods’ long and emotional run. For them, these connections make the spinoff feel earned rather than opportunistic.
As production on Boston Blue moves ahead, anticipation continues to build. With Donnie Wahlberg actively involved and more Blue Bloods alumni stepping back into the spotlight, the spinoff is shaping up to be one of the most closely watched franchise expansions in recent years.
For now, the mystery remains—but one thing is clear: Boston Blue isn’t done bringing the past into the present.
