Boston Blue Spinoff Premieres with Sean Reagan Recast, Extends Blue Bloods Legacy

The CBS spinoff "Boston Blue" continues the story of Detective Danny Reagan, played by Donnie Wahlberg, as he relocates to Boston to be near his son Sean, who is now portrayed by Mika Amonsen, replacing Andrew Terraciano. The recasting of Sean was a creative decision to reflect the character's new arc as a rookie Boston Police officer, bringing fresh energy and a slightly different interpretation while maintaining the core father-son relationship. The series premiere also explores Danny's ongoing relationship with Detective Maria Baez, played by Marisa Ramirez, providing continuity from "Blue Bloods." The show introduces the Silver family, a prominent mixed-race, interfaith Boston law enforcement family, highlighting themes of faith, family, and tradition. Sean and his friend Jonah Silver, both rookie cops, heroically respond to a building fire, which leads to Sean's hospitalization and Danny's deeper involvement in Boston. The creators emphasize that "Boston Blue" picks up the story in real time, addressing unresolved storylines and expanding the universe established by "Blue Bloods."
