Boston Blue Shifts Attention from Danny and Sean Ahead of Finale
Boston Blue will have a fresh direction for the remainder of the season, shifting its emphasis away from Danny and Sean Reagan.
In an exclusive interview with Us Weekly, Mika Amonsen shared insights about the second half of season 1, stating, “We witness Sean’s growth as a police officer. The cases are becoming more serious and challenging. The spotlight will slightly move away from Danny and Sean.”
Amonsen, who embodies the character of Sean, mentioned that the narrative will start “focusing a bit more” on the Silver family.
“We’re also introducing some fresh faces. Without revealing too much, there are a few new characters,” Amonsen teased. “Several more individuals will emerge on both sides of the story.”
Boston Blue, which debuted in October 2025, centers around Danny’s (Donnie Wahlberg) journey following his introduction on Blue Bloods, which aired from 2010 to 2024. The spinoff has allowed for a greater exploration of Danny’s relationship with his son Sean, which he is diligently working to mend throughout the season.
“Sean and Danny — at this point — have reached a good place. They’ve navigated the growing pains of working together and adapting to the dynamics of their relationship, and now we’re stable,” Amonsen elaborated. “We’re delving into other characters that are making their way into the show.”
Looking ahead, Amonsen hinted at a shift in the father-son dynamic, mentioning, “We’ll see Sean adopting a different energy than what we have seen before — one that mirrors Danny Reagan. An intriguing situation arises that Danny must handle.”
He added: “Danny finds himself needing to pull Sean back from fully embracing his own identity. He realizes Sean possesses more of his traits than he expected. There’s a pivotal moment where Danny must confront behaviors he used to display that he hopes Sean avoids. This aspect of an upcoming episode genuinely excites me, and I can’t wait for the fans to see it.”
Amonsen previously shared his experience working alongside Wahlberg, 56, to develop the on-screen relationship between Sean and Danny.
“The entire process has been incredibly smooth. Donnie makes it all so straightforward. I had a solid grasp of the character [who was created in Blue Bloods], so I brought that to the discussion with the showrunners and writers,” he recalled in November 2025. “[We talked about what they wanted to explore] and the direction they envisioned for the role.”
The duo focused on enhancing the dynamic between Danny and Sean. “Donnie was immensely helpful — understandably, given his extensive history with the show,” Amonsen noted. “Whenever I had questions, it was relaxed, and felt very organic with Donnie. He carries a fatherly energy about him. While he has played Sean’s father, he has also been a fantastic mentor to me in navigating a role and show like this. I couldn’t have asked for a better co-star.”
Boston Blue airs on CBS Fridays at 10 p.m. ET.
