Len Cariou Returns as “Pop Reagan” in Boston Blue—Emotional Reunion Teases Tears 💙
Len Cariou is set to reprise his role as Henry “Pop” Reagan in Boston Blue, visiting his rookie cop great-grandson Sean as he wears the uniform for the first time in the Blue Bloods spinoff airing Friday, April 3 on CBS. He also arrives with a special surprise for Danny Reagan (Donnie Wahlberg).
Executive producer Brandon Sonnier says Henry was the perfect choice for the next cameo because of his deep bond with Danny. On Blue Bloods, Henry often served as the family’s emotional anchor and the go-to source of wisdom, especially when tensions rose between Danny and Frank (Tom Selleck).
Sonnier explained that bringing Henry to Boston made sense as a “touchstone” for the Reagans, connecting Danny to his family while showing his journey after moving away.
He also revealed that filming Wahlberg and Cariou’s reunion was deeply emotional, with “tears on set,” highlighting the strong real-life and on-screen bond between the two actors.
