Danny Reagan’s Move in Blue Bloods Spinoff Explained After Recasting

Blue Bloods viewers are finally getting an explanation for why Donnie Wahlberg’s character, Danny Reagan, relocated to Boston for the show’s upcoming spinoff.

News broke on Wednesday, July 9, that Mika Amonsen is taking over the role of Wahlberg’s youngest onscreen son — who was originally played by Andrew Terraciano on Blue Bloods — for the new show Boston Blue. According to the character description, Sean is the inspiration for Danny’s move from New York City.

“Sean has relocated to Boston to start a new chapter as a Boston PD patrolman,” read the synopsis from CBS. “Sean committed himself to pursuing his family’s legacy but wanted to do so on his own terms, which meant joining a department outside of his hometown. Danny’s decision to stay in Boston gives this father and son duo a chance to reconnect on a deeper level.”

Wahlberg, 55, originated the role of Danny on CBS’ hit series Blue Bloods, which ran from 2010 to 2024. When the audience last saw Danny, he was taking some much-needed advice from his grandfather Henry (Len Cariou) about his personal life.

“I always told you not to bring the job home,” Henry reminded Danny in the 2024 finale, noting that the “problem now is you have no one not to bring it home to.” He then told Danny to promise he’d “find that someone” after this case.

Danny took the advice to heart, seemingly asking out his work partner, Baez (Marisa Ramirez), on a date. “You wanna get a pizza?” he said.

When Boston Blue premieres later this fall, Danny’s professional life will look a little different. He’ll be partnered up with Detective Lena Silver (Sonequa Martin-Green), the oldest daughter of a prominent law enforcement family.

Before the show officially went into production, Wahlberg told Fox News Digital in June that saying yes to Boston Blue was a “challenge,” adding, “I kept saying to myself, you know, if I’m really sincere about wanting Blue Bloods to carry on, here’s an opportunity to do it.”

Wahlberg was also asked about how Blue Bloods and Boston Blue would crossover.

“The viewers are saying, ‘How do we keep going with a Blue Bloods spinoff without the whole family?’” he noted. “And I share that. How do we do that, right?”

According to the actor, there have been conversations about introducing Boston Blue while still respecting its Blue Bloods origins. Wahlberg went on to say that any other member of the Reagan family is just a “phone call away.”

“Now, it’s just Danny going to this new world, but I can’t say a lot about it — but I could say, if he’s a Reagan, it will never be just Danny,” he shared at the time. “There’ll always be a Reagan a phone call away.”

Wahlberg continued: “And the traditions that the Reagans have, Danny wouldn’t abandon those traditions.”
