This announcement marks a significant moment for fans anticipating the next chapter in the “Blue Bloods” universe, with fresh family drama and new dynamics on the horizon.
According to CBS, Sonequa Martin-Green’s detective Lena Peters will be partnered with Danny Reagan, setting the stage for compelling narratives and complex relationships both inside and outside the police precinct. Wahlberg, who serves as an executive producer on “Boston Blue,” commented on the casting at the event. He emphasized the importance of Martin-Green’s selection by stating she was
“not the first choice — the only choice”
for the pivotal lead detective role.
Martin-Green expressed her enthusiasm for joining the celebrated Reagan family universe and beginning the journey of a new law enforcement legacy.
“We love the Reagans. We have all loved the Reagans for so long,”
she shared, referencing the central family of the original series.
“And I feel that we’ll love the Peters too. I’m super excited for this partnership, and to be back in a CBS family — and in this family, your family. It means a lot, and I’m grateful for it. I think we’re going to have a good time.”
Wahlberg further noted the impact of “Blue Bloods” and how the new show will build on its legacy, explaining,
“There are so many law enforcement families in this country. There’s not just the Reagans… There are other families around that have stories to tell too. Danny’s story will continue the Reagan family. You can’t have Danny without Reagans — there’ll be connective tissue. But we’re also going to get to discover a new family and and carry on the tradition of telling their stories.”
