Boston Blue slaps a recent coat of paint on Blue Bloods, the CBS procedural that ended its 14-season run final 12 months. Not solely does the spinoff transplant Donnie Wahlberg's Det. Danny Reagan from New York Metropolis to Boston, however it introduces a wholly new police dynasty for him to resolve instances alongside.

The collection' midseason finale, "Collateral Injury," finds Danny contemplating a everlasting spot on the Boston Police Division, ending on a surprising cliffhanger that can little doubt complicate the way forward for one key character.

So, what occurs within the Boston Blue midseason ending, and what does it imply for the Silver dynasty? Let's break it down.

Who’s Ronan Flaherty?

Ronan Flaherty (Jack Murray) is the person who killed Ben Silver, a decide and Silver household patriarch who was murdered previous to the occasions of the collection.

Ronan was serving time for the homicide, however is launched in "Collateral Injury" as a consequence of Mae's (Gloria Reuben) choice earlier within the season to analyze a corrupt assistant district legal professional. That ADA, it seems, labored Ronan's case. Whereas he's capable of be retried, the ADA's conduct complicates his unique conviction.

Ronan's launch throws the Silver household into disarray. Whereas Mae stands by her choice to observe the rule of regulation, her youngsters are none too happy to have their father's killer strolling the streets. Every of the Silvers cope in their very own method. Sarah (Maggie Lawson), the BPD's Superintendent of Detectives, pulls each open warrant tied to the housing initiatives the place Ronan grew up, hoping to safe some intel that may assist them lock up Ronan once more. Beat cop Jonah (Marcus Scribner), in the meantime, lashes out at his mom and siblings, adamant that retaining Ronan in jail was extra necessary than taking down a corrupt ADA.

Because the episode unfolds, we study that Ronan is a member of an Irish gang referred to as the Purple Saints, which leads the Silvers to contemplate how the gang could have been concerned in Ben's homicide. Previous to this discovery, they thought Ronan was merely searching for revenge for Ben placing him away on an previous drug cost.

Moreover, it seems "anyone rich" is defending the Purple Saints. Not solely does Ronan have a high-powered legal professional backing him, however that very same legal professional instantly begins representing Ronan's allies — with out them truly hiring him.

Who killed Marty?

Danny, in the meantime, catches a case with Lena (Sonequa Martin-Inexperienced) involving a 57-year-old Nationwide Safety Company (NSA) analyst named Marty who was bludgeoned to dying with a golf membership in his house whereas handcuffed. With somewhat assist from Steven Owen (James Madio), an previous Marine buddy of Danny's on the NSA, they study a number of key particulars about Marty.

First, he was concerned in indicators intelligence and lately suspended for his unlucky behavior of compromising top-secret intel by bringing it residence with him. Certainly one of his specialties was working to foil Russian-led cyber terrorism, which obtained him on the radar of terrorist group referred to as Volknet.

Suspecting that the homicide was linked to his work with the NSA, the primary suspect is a Volknet stooge named Nikolai Romanov (Nikita Naydenov). However Nikolai claims that whereas he was employed to observe Marty, they ended up changing into pals. He even has an alibi proving his innocence.

Possibly, then, the homicide was unrelated to nationwide safety. Marty, in any case, was lonely following the dying of his spouse and would typically hang around at a strip membership referred to as Filmore's. There, he cozied as much as a dancer named Aurora (Brandi Burkhardt), although he'd lately taken an curiosity in a newcomer to the membership named Lexi (Storm Steenson). Since a slick of physique oil was discovered on Marty's arm, they start to suspect a dancer might've been concerned.

When Danny and Lena interview Lexi, they study she'd made a home name to Marty's the evening of his homicide. Once they uncover Marty's watch, which was stolen off his physique, in her locker, they take her in for questioning.

Lexi maintains her innocence, saying the watch was planted in her locker. And as Danny and Lena dig deeper into the case, the small print simply aren't including up. For one, the physique oil on Marty's arm couldn't have been utilized by Lexi, as she's allergic to that particular model.

They start to suspect that Aurora framed Lexi, which they show by matching the DNA within the physique oil along with her personal (which Danny will get with a cherry stem she knotted along with her tongue).

Why did Aurora kill Marty?

Whereas we're initially led to consider that Aurora killed Marty due to him partaking in Lexi's companies over her personal, it truly does find yourself being linked to nationwide safety.

Aurora, hilariously, is revealed to be one other member of Volknet. (She even assumes a Russian accent as soon as Danny exposes her.) She broke into Marty's residence to steal labeled ciphers he'd taken out of the workplace.

Does Danny formally be a part of the BPD?

"Collateral Injury" begins with Sarah formally asking Danny to hitch the BPD. All season, he's been "on mortgage" from the NYPD, and if he accepts the badge he'll must retire from the NYPD.

The provide is tempting. He's gotten right into a groove with Lena, and organising store in Boston will hold him near his son, beat cop Sean (Mika Amonsen). They usually really need him.

"BPD is best with you right here," Sarah tells him.

However he's hesitant to simply accept it. He's been a New Yorker his complete life. It isn't till the ultimate moments of the episode that he seems to decide.

What occurs on the finish of the Boston Blue midseason finale?

No one is taking Ronan's launch tougher than Jonah, who asks to be placed on a patrol unit close to the initiatives the place Ronan is thought to reside. When he spots Ronan along with his buddies exterior a diner, he tells Ronan that he's going to be his "shadow." This leads Ronan to make a crack about Ben's homicide, prompting Jonah to throw a punch. After Ronan's allies descend on Jonah, Sean is pressured to drag his taser to interrupt it up.

This results in ample stress between the companions, in addition to a reprimand from Sarah, who says Jonah can be suspended if not for him being a Silver. Sean, who doesn't have that very same degree of privilege, fears that his profession will endure as a consequence of Jonah's recklessness.

Edwin (Ernie Hudson), Jonah's grandfather, comforts him with speak of how "revenge just isn’t the reply," however it's not sufficient to cease Jonah from discovering Ronan whereas off-duty. After recognizing him on a wet night, he follows his father's killer into an deserted constructing.

Danny, Lena, and Sean, fearing for Jonah's security, observe his automobile to the situation, however they're too late. Gunshots ring out, and so they ultimately discover a bloodied Jonah standing over Ronan's lifeless physique. "I'm sorry," Jonah says.

Understanding how unhealthy that is sure to get for the Silvers, Danny says that he's "gonna want that Boston badge, in any case."
