Donnie Wahlberg’s Boston Blue is set for a second season after its recasting, and the lineup is starting to take shape: key leads are returning, while some Blue Bloods-era faces remain uncertain or are not back—leaving one crucial romance and a lingering famil
Danny Wahlberg’s move from New York to Boston was only the beginning—now CBS is gearing up for Boston Blue’s second season, and the cast shake-up after a major recast is shaping what viewers can expect next.
The spinoff comes after Blue Bloods ran from 2010 to 2024. following the Reagan family and their work for the NYPD under NYC police commissioner Frank Reagan (Tom Selleck). Frank’s father. Henry Reagan (Len Cariou). also featured prominently. along with Frank’s children: daughter Erin Reagan (Bridget Moynahan) and sons Danny (Donnie Wahlberg) and Jamie Reagan (Will Estes).
Boston Blue picks up as former NYPD officer Danny takes on a position with the Boston P.D. He’s paired with detective Lena (Sonequa Martin-Green), the eldest daughter of a prominent law enforcement family. Even with many details kept the same. the show went through changes when Mika Amonsen was added to the cast as Sean—an identity that was originally created by Andrew Terraciano. Boston Blue has found success and was renewed after breaking records for CBS.
When Season 2 returns, these are the cast members set to continue—and the ones whose status is still unclear after the recasting.
Donnie Wahlberg
Donnie Wahlberg returns for Season 2 as Danny. His character introduced viewers to Boston Blue’s world after the move from New York to Boston and the shift from the NYPD to the Boston P.D.
Sonequa Martin-Green
Sonequa Martin-Green is back as Lena, and her detective partnership with Danny remains the engine for the cases in Boston Blue.
Ernie Hudson
Ernie Hudson returns as Reverend Edwin Peters. His character has appeared consistently in Season 1, and the expectation is that he will continue moving forward.
Maggie Lawson
Maggie Lawson will return as Sarah, Boston Blue’s Superintendent of Detectives at the Boston P.D. Season 2 is set to keep following her effort to balance work with her personal life.
Gloria Reuben
Gloria Reuben is returning as the Boston District Attorney, anchoring the Silver family presence at the center of the series.
Marcus Scribner
Marcus Scribner is set to continue as Jonah. The first half of Season 1 ended on a shocking note when Jonah appeared to have killed his father’s murderer. Showrunners Brandon Sonnier and Brandon Margolis promised viewers that Jonah would be the focus of the rest of the season.
Mika Amonsen
Mika Amonsen is back as Sean, a character who became a major part of the Blue Bloods spinoff after she was added following the recast.
Xochitl Gomez
Xochitl Gomez is returning as Penny, with Sean’s romance with Penny hinted to continue—though it remains unclear for how long.
What’s less settled after the recast
Marisa Ramirez
Marisa Ramirez returns as Maria, Danny’s girlfriend. The series has already explored that she’s made the drive to Boston several times, and her romance with Danny is expected to continue as their storyline is further developed.
Bridget Moynahan
Bridget Moynahan’s Erin—Danny’s sister—crossed over to Boston Blue first from Blue Bloods. Moynahan has since directed an episode, but a possible return on screen remains unclear.
Andrew Terraciano
Andrew Terraciano is no longer playing Sean after the recast. Still, the actor expressed interest in returning to the franchise in some capacity, and the show’s executive producers haven’t ruled it out.
Tony Terraciano
Tony Terraciano, who played his sibling in Blue Bloods, has not returned for Boston Blue. However, his character Jack was mentioned, leaving the door open for an appearance.
The through-line is plain: the core of Boston Blue’s current case team—Danny. Lena. and the supporting cast tied to the Boston P.D. and its power structure—is positioned to keep moving forward. At the same time. the recasting that elevated Sean into a major spinoff character still echoes around the edges. with Andrew Terraciano’s possible franchise return and uncertainty hanging over who else will step back into view.
For now, Season 2 is shaping up as a continuation built on what worked, with the show’s biggest unanswered questions sitting right where Season 1 left them—around Jonah’s focus, and the future of Sean and Penny’s romance.

So it’s basically Blue Bloods but in Boston again? Cool I guess.
Wait, the romance is “crucial”?? I didn’t even know there was romance lol. Also why recast stuff if they’re keeping the same details, seems weird.
I’m confused about the whole Mika Amonsen/Sean thing. Like didn’t that character already exist? Sounds like they just changed the name and called it a recast. I liked the original actor more.
Ernie Hudson being back as a Reverend is the only reason I’ll watch season 2, not gonna lie. Also Donnie Wahlberg moving to Boston still feels like a stunt, and CBS always does this—renew fast then scramble for who’s staying. The “famil Danny” part in the article was probably a typo but it kinda makes it sound like they’re bringing family drama back, which I’m here for even if it makes no sense.
