After playing Sean Reagan on 14 seasons of Blue Bloods, Andrew Terraciano opened up about how he found out that his beloved role was recast in the Boston Blue spinoff.
“I had somebody call me — actually the day that I was graduating — and they had spoken to my mom and she called me [crying],” Terraciano, 22, exclusively told Us Weekly. “They were like, ‘They might be looking for a different Sean.’”
Terraciano subsequently spoke to Donnie Wahlberg, who played his onscreen dad.
“Shortly after we got the news, Donnie called me. It was a really beautiful moment of getting to hear from an old friend but also somebody that you respect so much and have learned so much from,” he recalled. “We had such an amazing experience on Blue Bloods that when we talk we’ll always be friends and family first. I’m happy that there are so many other people that now get to share in that amazing experience.”

Terraciano got his start on CBS’ Blue Bloods, appearing in nearly 300 episodes from 2010 to 2024. He also performed in several short films — and wrote one himself — while attending New York University.
Andrew’s role as Sean allowed him to share the screen with brother Tony Terraciano, who played Donnie’s eldest son, Jack Reagan. Despite becoming a beloved presence at the Reagan dinner table, the Blue Bloods spinoff, Boston Blue, premiered in October with Mika Amonsen now starring as Sean.
“It’s beautiful because you’ll always remember every single line and every day that you had the opportunity to be that character,” Terraciano noted to Us about his time on the hit CBS show. “It doesn’t mean for even a second that somebody else can’t go and do something beautiful with it.”
Terraciano weighed in on Sean continuing to live on, saying, “I got the joy of playing Sean, and I got to send him off into the world. Now somebody else gets that joy. We’re both getting to show what we do and then send Sean off into the world.”
Before Terraciano broke his silence, Amonsen showed support for his predecessor.
“I definitely felt a ton of pressure at first. I felt the pressure to respect an actor before me because I wanted to respect Andrew the best I could,” Amonsen recalled to Us in November. “There were even certain visual choices that I made that I wanted to keep in terms of hair styling and certain ways of being [as Sean].”
Amonsen discussed trying to pay tribute to Terraciano’s take on the character.

“I really want to maintain Sean as close as I can in the ways that I do it out of respect for this character that everyone loves — but also the character Andrew built,” he continued. “When I booked the show, it all happened really quickly. It was within about a week’s time and I was really thrown into it quickly. I did binge watch as much as I could and I found doing the later seasons was more helpful. I wanted to get a sense of who Sean was toward the end of the show. I really wanted to get a sense of his character at that point into adulthood and his relationship with Danny.”
After rewatching key episodes of Boston Blue, Amonsen found ways to celebrate Terraciano’s performance.
“I wanted to respect Andrew’s portrayal of Sean as much as I could — but also adding something to my own version. The showrunners Brandon Sonnier and Brandon Margolis have been really good at giving me a lot of freedom to explore that new dynamic with Donnie,” he shared. “Watching Andrew’s performance, I actually noticed a lot of similarities just between us as people, and our energy. It’s quite upbeat. I have a lot more of an upbeat energy myself. So that was a bit comforting. I definitely kept that within myself and didn’t feel like I was obligated to change that part of me — which was nice — in terms of making it my own.”
Terraciano, meanwhile, has appreciated how fans have shared their love for his version of Sean since Blue Bloods came to an end.
“I can’t say that I expected it but I appreciate it. It’s so meaningful to know that people love the character that I got to share in creating. I didn’t expect it to say the least,” he shared. “I appreciate it because not only has there been such an outcry of love from the community but there’s also a very clear love coming to the show.”
He continued: “It’s hundreds if not thousands of people who depend on their livelihood for a show to be made. It really is amazing that part of that character remains. Somebody can look back and say, ‘I want to pay homage to that. I want to respect that and I want to work on making something beautiful.’”
Which ‘Blue Bloods’ Stars Have Reprised Their Roles on ‘Boston Blue’ So Far?
Terraciano has yet to watch the spinoff as he focuses on his studies — but he is interested in seeing the final product, which was recently renewed for season 2.
“I’m going to give it the time and the respect that it deserves,” he noted. “[But in terms of returning in some capacity] I said it to Donnie on the phone. If he says the word, I’ll be there. Not just with Blue Bloods or Boston Blue but with anything in life.”
For now, Terraciano is currently getting his Masters and looking for more opportunities in the acting space.
“At the end of last spring, I got the fantastic opportunity to work in a dear friend director Sabrina Carlier’s rendition of Annie Baker’s The Antipodes. Not only did I have that amazing opportunity that was my first play that I’ve ever been in but it really pulled me into the theater world,” he explained. “It showed me how much love I have for all forms of acting. I helped produce a friend’s short film recently, and I look forward to every opportunity that I get to act.”
He concluded: “You get a passion and you can’t get rid of it to continue to act and continue to participate in creating in any way, shape or form. I would love more than anything to be an actor for the rest of my life. But I’m a huge Star Wars fanatic so I would really do anything [in that universe]. And I would love to try out a sitcom.”
Blue Bloods is streaming on Paramount+. Boston Blue airs on CBS Fridays at 10 p.m. ET.
