‘Boston Blue’ Recasts Sean Reagan, Taps Mika Amonsen As Danny’s Son In ‘Blue Bloods’ Offshoot

By Nellie Andreeva

Danny Reagan’s youngest son Sean will look a little different when he
appears alongside his dad on CBS’ upcoming drama series Boston Blue. Mika Amonsen has been cast as a series regular opposite Donnie Wahlberg on the
Blue Bloods offshoot, taking over the role of Sean Reagan.

On Blue Bloods, Sean was played by Andrew Terraciano who recurred
throughout the series’ 14-season run. According to sources, the recasting stems from the character taking a new creative direction on Boston Blue as
he follows the Reagans’ career path into law enforcement. Meanwhile, the addition of Sean to the offshoot helps explain Danny’s move from his native New York to Boston.

On Boston Blue, Wahlberg reprises his role as NYPD Detective Danny Reagan
as he takes a position with Boston PD. Once in Boston, he is paired with Detective Lena Silver (Sonequa Martin-Green), the eldest daughter of a prominent law enforcement family.

The show will find Sean in Boston where he had relocated to start a new
chapter as a Boston PD patrolman. Committed himself to pursuing his
family’s legacy, he wanted to do so on his own terms, which meant joining a department outside of his hometown. Danny’s (Wahlberg) decision to stay in Boston gives this father and son duo a chance to reconnect on a deeper
level.

Danny’s sons Jack and Sean were played on Blue Bloods by real-life brothers Tony Terraciano and
Andrew Terraciano. While the oldest, Jack, left for college in Season 9 and rarely appeared on the show after that as he pursued a career in medicine,
Sean remained a fixture on Blue Bloods as he went though high school and
mulled various career choices, including becoming a firefighter. Last seen
at the dinner table in the Blue Bloods series finale, he was off to college
at the time, so Boston Blue will explain what prompted his decision to
become a Boston cop.

Sean is now the first Reagan besides Danny confirmed for the new Blue
Bloods universe series, with others likely to make guest appearances.

In addition to Wahlberg and Martin-Green, Amonsen joins fellow Boston Blue series regulars Maggie Lawson as Sarah Silver, Marcus Scribner as Jonah
Silver, Gloria Reuben as Mae Silver and Ernie Hudson as Reverend Peters

Boston Blue, which just started production this week for a fall premiere in Blue Bloods‘ Friday 10 PM time period, is produced by CBS Studios in association with Jerry Bruckheimer Television. Brandon Sonnier & Brandon Margolis showrun and executive produce. Jerry Bruckheimer, KristieAnne Reed
and Wahlberg also serve as executive producers. The series will be
distributed by Paramount Global Content Distribution.

Which means he can't be 350 pounds and inhaling the entire Sunday dinner anymore.

Meanwhile, the addition of Sean to the offshoot helps explain Danny's move from his native New York to Boston.

Not really. He has two sons, one of which moved away somewhere long ago and Danny never even visits, let alone uproots himself and gives up that sweet
NYPD pension and post-retirement bennies for him.

Wasn't that the "older" son's actor?...

Yeah, I'm wondering if this spinoff will ever reference any of:

1) Danny's other (older?) son,
2) Danny's real "love", Baez, or
3) Danny's dead wife (when the show callously killed off Amy Carlson's character in order to save on cast salaries!)
4) Any of the rest of the Reagans!!

No. The older thinner brother is still off in college, and the younger
brother still comes to family dinner and eats both of their portions.

Or their worthless cousin Nicki

2) Danny's real "love", Baez, or

You misspelled Jennifer Esposito.

3) Danny's dead wife (when the show callously killed off Amy Carlson's character in order to save on cast salaries!)

Hey, as long as they got rid of Nicki

4) Any of the rest of the Reagans!!

Oh, we’ll probably get news about his worthless aunt in law and the baby


Or Spenser for hire. Or Jesse Stone.

The older brother went off to the same local college as the younger
brother. I think he’s still there. He came to dinner in the finale.

I agree it doesn’t explain anything. The younger brother went off to
college years ago as well.

To get Danny, did Bastan have to send a detective in trade?

I don't get this go work at another big city police force at middle age, retaining your rank thing.

I don't get this go work at another big city police force at middle age, retaining your rank thing.

I know a guy who spent 18 years in the St. Thomas (Ontario) Police
Department, then he left and joined the OPP (Ontario Provincial Police,
the equivalent of a state police in the US) for 12 years before
retiring. I asked him if he kept his rank but he said he had to start
over from scratch at the bottom of the rank hierarchy. (Mind you, he
retired from the OPP at the same rank as he'd left the St. Thomas police
so he clearly rose up the ranks considerably quicker than if the OPP was
his first policing experience.)

Based on that, I'd be surprised if Danny got to start at the same rank
he'd had in the NYPD but what do I know? The rules may be different on
your side of the border.

Yeah, that would piss off all the Boston cops waiting to promote, to have some New York hotshot come in and jump the line in front of them.
