2025 was a big year for TV shows recasting major characters — starting with Blue Bloods spinoff Boston Blue replacing Donnie Wahlberg‘s son.
Danny’s (Wahlberg) journey in New York was featured on CBS’ Blue Bloods, which ran from 2010 to 2024. The spinoff, which premiered in October, kicked off with Danny visiting Boston after Sean (Mika Amonsen) ended up in a coma. This version of Sean looked a little different after the role was previously played by Andrew Terraciano.
“There’s been some negativity, for sure,” Amonsen exclusively told Us Weekly of taking over the role. “But when I look under those posts that have the negativity, there’s a lot of fans rallying for Sean and people saying that they really enjoyed this character that I’ve created — or my version of character.”
Amonsen noted that he wanted to make Blue Bloods fans happy with his performance, saying, “They’re really enjoying the show and they love where it’s going in terms of Sean and that makes me happy.”
Terraciano, meanwhile, broke his silence to Us about the shakeup.
“I had somebody call me — actually the day that I was graduating — and they had spoken to my mom and she called me [crying]. They were like, ‘They might be looking for a different Sean,’” Terraciano shared with Us in December about the onscreen change. “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.”

‘RJ Decker’
Scott Speedman‘s new ABC show cast Station 19‘s Jaina Lee Ortiz as a series regular. She will play Emi Ochoa, a “shrewd-if-unpredictable daughter of a very powerful, very corrupt state senator” with ties to RJ’s (Speedman) past.
