Blue Bloods ties (for readers searching “blue bloods” and “cast of blue bloods”)
The spinoff positions Danny in Boston while preserving the family-and-work balance that defined Blue Bloods. Entertainment Weekly emphasizes that Bridget Moynahan returns as Erin Reagan in the premiere, and notes the show’s “buddy-cop chemistry” between Wahlberg and Martin-Green while embracing an “if-it-ain’t-broke” procedural template.
EW also confirms Sean Reagan is now played by Mika Amonsen, who studied the character’s “dynamic with Danny” from Andrew Terraciano’s later episodes before stepping into the role.
Local color & quotes from set
Donnie Wahlberg described filming on Boston Common and stressed that his New York cop “doesn’t really like Boston,” adding, “The Boston accent cannot come out to play.” He promised, “We’re going right to Fenway Park. We’re running, chasing a bad guy along the Freedom Trail,” and spoke about taking the cast through Dorchester, including “the Ice Creamsmith on Dot Ave.”
Marcus Scribner (who plays rookie cop Jonah Silver) said that being in Boston with Wahlberg felt like being “with the Pope or something,” and that visiting Boston Police Precinct 13 in Jamaica Plain was “really cool and insightful.”
Sonequa Martin-Green told CBS Mornings that joining another beloved franchise was something she “just couldn’t have expected,” after earlier runs on The Walking Dead and Star Trek: Discovery.
Episode 1 confirmation
CBS lists Season 1, Episode 1 as “Faith and Family”, with an air date of Oct 17, 2025, and the series banner stating “NEW EPISODES FRIDAYS 10/9c.”
