Premieres: Friday, Sept. 28 at 10/9c
Where We Left Off: Frank and the NYPD prevented a terrorist attack, which he kept secret from his family since it overlapped with the clan's most sentimental holiday, Mother's Day. Tension between Danny and Jamie came to a head over an arrest, which led to the elder brother and Jackie rescuing a boy from a cold case.
What's Next: Lots of changes and new faces. Linda will return to work as a nurse, which causes problems between her and Danny. Jamie will get a new partner who can't keep his mouth shut. And we'll finally meet Erin's ex-husband, Jack Boyle (Peter Hermann), whom she'll face in court. Even better? They're arguing over the constitutionality of one of Frank's new building search policies.
