The highly anticipated Blue Bloods spinoff, Boston Blue, is set to arrive on the CBS fall 2025 schedule, and excitement is building fast. The new series follows Donnie Wahlberg as he reprises his fan-favorite role as Detective Danny Reagan, this time taking on a new chapter with the Boston Police Department. Ever since the spinoff was announced, fans have been wondering whether any other members of the Reagan family might join him and now, that question has finally been answered.
As filming continues, Wahlberg took to Instagram on Friday to share a photo from the Boston Blue set that immediately caught fans’ attention. Standing beside him was on-screen sister Bridget Moynahan, and the moment came with a major reveal. Wahlberg announced that Moynahan will not only be lending her talents behind the camera as a director, but will also be reprising her role as Erin Reagan, who will appear on the series and reunite with her brother in Boston at least for a short time.
The news is a welcome one for longtime fans. It’s been just about a year since Blue Bloods wrapped production after an impressive 14-season run, but seeing Wahlberg and Moynahan working together again feels like a long-awaited reunion. The Reagan family wasn’t just a fixture on screen it became a genuine family off screen as well. Moynahan’s involvement offers hope that she won’t be the last familiar face to cross over into the spinoff.
Details about Erin Reagan’s appearance are being kept under wraps, leaving fans to speculate about what brings her to Boston. Perhaps it’s simply a sibling visit, or maybe she’s checking in on Danny while offering updates on her life with Jack following the events of the series finale. Whatever the reason, seeing Moynahan and Wahlberg share the screen again is sure to be a highlight. Fans can’t help but wish Jamie might eventually join them, too.
While Moynahan is the first original cast member aside from Wahlberg himself confirmed to return, she isn’t the only Reagan making the move to Boston. It was previously reported that Danny’s youngest son, Sean, will relocate with his father. However, the role has been recast, with Mika Amonsen stepping in as Sean begins a new chapter as a Boston PD patrolman. Whether audiences will also see Sean’s older brother Jack, previously played by Tony Terraciano, remains unknown.
One thing is clear: Boston Blue is already honoring its roots, and with familiar faces beginning to reappear, the Reagan legacy is far from over.
