Boston Blue is keeping the Blue Bloods universe alive with the return of Donnie Wahlberg as Danny Reagan, but the spinoff is also introducing many new faces. The CBS police procedural series, developed by Brandon Sonnier and Brandon Margolis, begins with Danny’s move to Boston. As fans of the original show know, Blue Bloods didn’t end with Danny leaving New York City or with any kind of tease that he was thinking of transferring to the Boston Police Department. Alas, Danny is coming to Boston, where he’ll meet many new people.
