CBS’ upcoming Blue Bloods offshoot has added another Reagan — though he will look a bit different when he shows up.

A “universe expansion” of the long-running family/crime drama, Boston Blue (airing Fridays at 10/9c this fall) finds Donnie Wahlberg’s Danny Reagan taking a position with the Boston Police Department. There, he is paired with Detective Lena Silver (Star Trek: Discovery‘s Sonequa Martin-Green), the eldest daughter of a prominent law enforcement family.

Mika Amonsen — whose credits include TV’s The Republic of Sarah and Hudson and Rex, as well as the 2023 slasher film Thanksgiving — has been cast in the series regular role of Sean Reagan, Danny’s youngest son (of two).

Sean of course was originally played across all 14 seasons of Blue Bloods by Andrew Terraciano, in what was practically Terraciano’s only acting role.

In Boston Blue, Sean has relocated to Boston to start his own new chapter,as a patrolman for the Boston PD — thus paving the way for his father’s own major move.

“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,” the official character description reads. “Danny’s decision to stay in Boston gives this father-and-son duo a chance to reconnect on a deeper level.”

The Boston Blue cast also includesGloria Reuben(ER) as Mae Silver, family matriarch and Boston’s District Attorney; Ernie Hudson (NBC’s Quantum Leapreboot) as Lena’s grandfather, Reverend Peters, a renowned pastor of a historic Baptist church in Boston;Maggie Lawson(Psych) as Boston PD Superintendent Sarah Silver, Lena’s “strong-willed” and “decisive” stepsister; and Marcus Scribner (black-ish) as Jonah, Lena and Sarah’s rookie cop brother.
