Mika Amonsen has also been cast as Wahlberg’s on-screen son, Sean Reagan, replacing Andrew Terraciano, who played Sean in all 14 seasons of Blue Bloods.
Moynahan previously said that saying goodbye to her Blue Bloods “family” was an emotional experience.
Weeks before they wrapped filming on the final season of Blue Bloods, Wahlberg and Moynahan stopped by The Drew Barrymore Show, and Wahlberg admitted that the cast felt “more upset and sad” than “happy and satiated” about the show ending.

“I think it’s more saying goodbye to the people behind the characters,” Moynahan said of the emotions on set. “We’ve created such a family on set with each other and the crew — most of the crew’s been with us for 14 years, so we’ve been through a lot of weddings, births, deaths, and everything. We’ve been through it all with each other.”
She also praised Wahlberg as her “biggest supporter” on set, and he said she’s “phenomenal.”
