Will Frank Reagan Return For The Blue Bloods Spinoff? I’m Not Sure Tom Selleck And Donnie Wahlberg Are On The Same Page

Side by side: Danny Reagan giving sideeye while standing on a basketball court in Boston Blue, Frank Reagan looking out through a car window in Blue Bloods.

Mild spoilers for anyone who hasn’t yet watched Boston Blue’s latest episode airing on CBS or streaming via Paramount+ subscription.

To the surprise of presumably no one, Boston Blue has become a steady hit for CBS and earned its Season 2 renewal even before its midseason finale aired. With only three episodes left to go before Season 1 bows out of the 2026 TV schedule, the drama gave Donnie Wahlberg’s Danny Reagan a big reunion with former Blue Bloods co-star Bridget Moynihan, who popped in for her second appearance as Erin before taking Danny to the Reagans’ time-honored family dinners. Still no Frank, though.
