It’s the beginning of the end. The first photos from the final season of Blue Bloods have been revealed, in addition to the first plot details about the Season 14 Part 2 premiere.

TV Insider previously exclusively announced that Debi Mazar and Miro Sorvino would guest star in the last installment and revealed the first look at their characters. The new photos show Mazar in the premiere alongside her former Younger costar Peter Hermann, who returns in his guest star role as Jack Boyle.

The final episodes of Blue Bloods kick off on October 18 at 10/9c on CBS. Here’s the official description for the episode, “Life Sentence”: “The Reagans’ professional lives converge when an allegation of jury tampering against Erin intertwines with Danny and Baez’s homicide case and Eddie’s bond to a child murder witness; Frank clashes with his friend and confidant Archbishop Kearns over the death penalty; and when Jamie’s car is stolen, he joins forces with his nephew, Joe Hill, to recover it.”

Stacy Keach and Will Hochman also guest star in the premiere. See Tom Selleck, Donnie Wahlberg, Bridget Moynahan, Will Estes, and more of the Reagan gang in the Blue Bloods Season 14 Part 2 gallery below.

Eveline is described as a no-nonsense prosecutor, and that certainly seems clear in this photo of her in a tense moment with Erin and Anthony Abetemarco (Steve Schirripa)
