Sad news: Veteran star Tom Selleck (Blue Bloods, Magnum, P.I.) has passed away

While many are settling in to watch the World Series between the Toronto Blue Jays and the Los Angeles Dodgers, the new episode of Boston Blue (Fridays at 10:00 p.m. ET/PT on CTV in Canada, CBS in the U.S.) also started with a little baseball. Episode 2 begins with Danny Reagan, played by Donnie Wahlberg, leaving Fenway Park with his son Sean (Mika Amonsen), after the New York Mets beat the Boston Red Sox.

This comes just as Sean and his friend Jonah Silver (Marcus Scribner) are a day away from being partnered Boston PD officers. While Danny tells his son he needs to assert some dominance in the partnership, Jonah’s sister, detective Lena (Sonequa Martin-Green), is doing the same with her brother. Danny and Lena both specifically discuss how the person who drives, picks the music and decides where to eat lunch has control.

Sean and Jonah aren’t worried because they’ve been best friends since the police academy, but Danny and Lena correctly identify that friendship gets complicated when you’re partnered officers.

While Sean and Danny are heading away from Fenway, they hear gunshots and see a man on the ground, covered in blood, with tape over his mouth and his hands tied. Danny is still on loan to the Boston PD, so he works with Lena on the case, as he was the first to arrive at the scene. One witness says he saw the man jump out of a blue van and run to the park before the gunshots went off.

In an unexpected surprise, Lena’s mom, Mae (Gloria Reuben), the district attorney, arrives at the crime scene. The victim is a man named Winston Ballard, who walked away from a fortune to be a whistleblower in a Ponzi scheme case Mae was working on, involving someone named Lou Malakov (Paul Miller).
