‘Boston Blue’ Officially Brings Back a Major ‘Blue Bloods’ Star Tonight

The Reagan family has been a huge part of our lives and of American culture since 2010, and while Blue Bloods officially concluded its 14-season run in December 2024, CBS clearly wasn’t ready to say goodbye to one of its most beloved television families. The arrival of Boston Blue has given Donnie Wahlberg‘s Danny Reagan a new city to police, a new collection of workmates, and plenty of dangerous criminals. But even with hundreds of miles separating Danny from his old stomping grounds in New York, some family connections are simply too strong to leave behind. And this week, one particularly familiar face is about to make life in Boston considerably more complicated.

Collider is thrilled to be debuting a new sneak peek from Boston Blue Season 1, Episode 5, titled “Blood Diamonds” — airing this evening exclusively on CBS — which sees the return of Will Estes as Jamie Reagan alongside Wahlberg’s Danny Reagan. Jamie’s visit to Boston takes an unexpected turn when he and Danny are drawn into a diamond heist linked to a violent family feud, forcing the brothers to confront lingering tensions of their own. Meanwhile, Mae faces a difficult case after swatting results in a man’s death, Lena investigates a series of suspicious deaths linked to one of Reverend Peters’ parishioners, and Sarah and Seth encounter an unexpected hurdle while planning their wedding.

‘Boston Blue’ Is Keeping the Reagan Family Legacy Alive

Blue Bloods followed multiple generations of the storied Reagan family as they, from their various levels of law enforcement, attempted to navigate the darker sides of New York City. The series was brought to a close after 293 episodes, but CBS continued the franchise with Boston Blue, which follows Danny Reagan as he begins a new chapter with the Boston Police Department.

The series stars Wahlberg (Blue Bloods) as Danny Reagan, Sonequa Martin-Green (Star Trek: Discovery) as Lena Silver, Maggie Lawson (Psych) as Sarah Silver, Marcus Scribner (Black-ish) as Jonah Silver, Gloria Reuben (ER) as Mae Silver, and Ernie Hudson (Ghostbusters) as Reverend Edwin Peters.
