Quick catch-up from Episode 2

Episode 2, 'Teammates,' paired up Danny Reagan (Donnie Wahlberg) and Lena Silver (Sonequa Martin-Green) on a murder case involving a whistleblower tied to one of District Attorney Mae Silver's (Gloria Reuben) prosecutions. Meanwhile, rookies Jonah (Marcus Scribner) and Sean (Mika Amonsen) geared up for their first official day with the Boston Police Department. If you liked the old-school, case-of-the-week energy of Blue Bloods, the first two hours have been right in that zone — grounded, procedural, and unflashy in a good way.

What the show is, in one line

'Follow NYPD officer Danny Reagan as he takes a position with Boston PD. Once in Boston, he is paired with detective Lena Peters, the eldest daughter of a prominent law enforcement family.'

Small heads-up: the show materials can not seem to decide on the detective's last name — Episode 2 refers to her as Lena Silver, while the official synopsis says Lena Peters. Given that Mae Silver is Boston's DA in the show, 'Silver' would make sense thematically. Either way, she is Danny's new partner, and the dynamic is the point.
