Will Estes is returning to the Reagan clan next week: the actor will appear as Jamie Reagan on the Nov. 6 episode of Boston Blue, reuniting on screen with Donnie Wahlberg for the first time since Blue Bloods wrapped in December 2024. CBS has released photos and a synopsis that suggest the reunion is built into a tense, plot-driven hour with emotional stakes for both characters.
The episode, titled “Blood Diamonds”, drops at 10/9c and anchors a case that pulls Jamie and Danny into a brazen diamond heist linked to a violent family feud. According to the network summary, investigating the crime forces the brothers to reckon with unresolved friction in their relationship.

Behind the scenes, Wahlberg said the guest turn carried personal weight. He described reconnecting with Estes as a meaningful experience, noting that the pair carried both on-screen history and a long off-camera relationship into the scenes. Production insiders say the rest of the Boston Blue cast welcomed the return warmly, creating a collaborative atmosphere during filming.
For viewers, the appearance serves two obvious functions: it ties Boston Blue more visibly to the Blue Bloods universe and offers longtime fans a rare character reunion. Whether the cameo will have lasting narrative consequences for either series remains to be seen, but it is likely to be a ratings and publicity boon on premiere night.
