Jack Reagan could get a fresh update in BOSTON BLUE Season 2, but Danny’s older son still doesn’t have a confirmed ticket to Boston.
“It’s possible,” BOSTON BLUE co-creator, co-showrunner and executive producer Brandon Sonnier told TV Insider when asked whether viewers would see or get updates on Jack this season.
That answer leaves two doors open: an appearance or simply news about what Jack is doing. It does not confirm a guest episode, a return for actor Tony Terraciano or a decision to recast his BLUE BLOODS character.
For viewers keeping track of Danny’s family, Jack hasn’t vanished from the story. The first season’s December 2025 midseason finale placed him in Africa with Doctors Without Borders while attending medical school, far from his father and younger brother Sean.
“We never want to lose sight of the fact that Danny has two sons,” Sonnier told TVLine in December 2025, explaining why Jack’s offscreen life still matters to the story.
“Part of placing Jack so far away was logistical — it gives Danny the space to fully focus on Sean right now, because there’s not a lot he can do for Jack,” he added in that earlier interview.

Sonnier described Jack as thriving and following the Reagans’ calling to serve, just through medicine rather than a police badge. The distance gave the writers room to concentrate on Danny and Sean without suggesting Danny had forgotten his other child.
There’s an important seasonal distinction here, too. In that original TVLine conversation, co-creator, co-showrunner and executive producer Brandon Margolis ruled Jack out of the back half of Season 1 while remaining open to a future appearance that fit the story.
The new Season 2 answer is more open-ended, not a casting announcement. Tony played Jack opposite his real-life brother, actor Andrew Terraciano, as Sean in BLUE BLOODS; actor Mika Amonsen now plays Sean in BOSTON BLUE, but that change doesn’t establish what the creators would do with Jack.
Meanwhile, Danny’s relationship with the son who is in Boston has its own growing pains. In the new TV Insider interview, Sonnier said Danny is learning when to step in and when to let Sean make his own way.
“It’s about being there when Sean needs it and stepping back when it’s time to let Sean venture out on his own,” Sonnier said.
The creators also plan to bring new mentors into Sean and Jonah’s precinct. In the Season 2 conversation, Margolis said Sean will have to decide which influences to trust, while Sonnier described Sean’s interest in traditional, proactive police work alongside Jonah’s push toward community outreach.
That’s a familiar parenting challenge, even without two sons on different continents. CBS’s current series description puts actor Donnie Wahlberg’s Danny between mentorship and fatherhood as Sean and fellow officer Jonah Silver, played by actor Marcus Scribner, forge their own paths.
BOSTON BLUE returns Friday, Oct. 9, at 10 p.m. ET/PT on CBS, with Paramount+ streaming options. The network’s premiere announcement confirmed actor Len Cariou’s return as Henry Reagan, giving viewers a definite family reunion while Jack’s next chapter remains a possibility.
