'Blue Bloods' honors Treat Williams with farewell to late actor's character

"Blue Bloods" paid tribute to Treat Williams Friday in a farewell episode to his character, Lenny Ross.

Ross, the former partner of New York City Police Commissioner Francis "Frank" Reagan (played by Tom Selleck), was last featured in season 13 when it was revealed his character had cancer. On Friday's show, Lenny succumbed to the disease.

Williams died in June following a vehicular accident in Dorset, Vermont, according to police. He was 71.

On Friday's episode, Frank grappled with the decision of having to make Lenny's daughter Tess face prosecution after she's arrested following a bar fight, according to Deadline.

"He was my best friend. And I’m gonna honor that by doing what’s best for his daughter," Frank said. He later opted to refer Tess to a good defense attorney.

In a final scene over a family meal, Frank paid tribute to his former partner.

"Lenny Ross was my oldest friend, my closest confidant, my getaway driver," Frank said, according to the outlet. "And I lost him this week. And it hurts like hell. But Lenny would hate it if we got all teary and quiet and sad, so Lenny: We’ll miss ya. And save me a seat at your table, and I’ll see ya on down the road."

The episode ended with a photo of Treat with his arm around Tom, and the message, "In memory of our great friend, Treat Williams 1951-2023." 

The Vermont State Police confirmed Williams' death in a statement last year, saying Williams was driving along Morse Hill Road at approximately 4:53 p.m. when his motorcycle was unable to avoid a Honda SUV and the two vehicles collided. 

"The Vermont State Police is investigating a crash between an SUV and a motorcycle Monday afternoon, June 12, 2023, in Dorset in which the operator of the motorcycle suffered fatal injuries," the statement read. "The motorcyclist is identified as Richard Treat Williams, 71, of Manchester Center, Vermont."
