Warning: Major spoilers for Reacher season 3 episode 4 "Dominique" below!Xavier Quinn is the main villain of the Lee Child Jack Reacher books is that the author is rarely concerned with crafting bad guys who feel like plausible threats. Child assumes readers already know Reacher will win, so the villains can seem a little one-note and ineffective. Amazon's adaptation inherited this issue, with the first two series lacking antagonists who posed any real threat.

Reacher vs Paulie fight, but it's the showdown with Quinn that the season is truly building to.

What Reacher Reveals About Xavier Quinn's Role In The Military & Backstory

Reacher season 3 sets a high bar for Quinn, with Alan Ritchson's anti-hero telling DEA Agent Duffy (Sonya Cassidy) that he is the "worst person" he's ever encountered. Considering the vile acts the bad guys from previous series committed (including torture and mutilation), that's a worrying statement. Quinn earns the title, though, with episode 4 "Dominique" detailing his worst crime and the reason Reacher detests him so deeply. "Dominique" is largely told in flashback, with Reacher recounting his friendship with mentee Dominique Kohl (Mariah Robinson), and their investigation into Quinn.

A therapist report diagnosed Quinn as having "malignant narcissist personality disorder," and highlighted his lack of empathy or remorse...

After arresting a military officer named Gorowski (Johnathan Sousa) for selling classified documents, Kohl and Reacher learn he was being coerced by military intelligence officer Quinn, who threatened Gorowski's family. Reacher later hears a therapist report about the young Quinn, who had violent tendencies and a history of harming animals. The report diagnosed Quinn as having "malignant narcissist personality disorder" and highlighted his lack of empathy or remorse and the apparent joy he gains from inflicting torture.

Quinn's gruesome murder of Kohl underlines this torture trait, where he kidnaps and interrogates the young sergeant after a failed attempt to arrest him. Reacher discovers Kohl's mutilated corpse on Quinn's isolated farm, where he also finds the latter attempting to flee. Quinn tries to convince Reacher that he and Kohl were secretly working together, but after Reacher asks him what her "first name" was, Quinn's silence reveals he's lying. Reacher then marched Quinn out to the edge of a cliff and shot him in the head with his own pistol.

What Crimes Xavier Quinn Was Committing In The Military

Quinn wanted to get rich off his time in the Army

Quinn had made a profitable sideline in the Army selling military secrets, which allowed him to live a suspiciously extravagant lifestyle outside his duties. Presumably, Quinn planned to get rich off selling sensitive material to foreign countries before retiring early, but Reacher and Kohl's investigation ruined that. Gorowski revealed Quinn had kidnapped his young daughter and held her overnight, but while nothing happened to her, Quinn threatened horrific acts unless Gorowski gave his full cooperation.

Quinn performer Brian Tee previously co-starred with Alan Ritchson in the 2016 sequel Teenage Mutant Ninja Turtles: Out of the Shadows.

Quinn was also willing to kill to cover his tracks, since murdering the officers investigating him (Kohl included) would have seen any case against him collapse. This meant he would have come after Reacher too, but Jack catches up to him before he has a chance to do so. Throughout this time in military intelligence, Quinn's crimes included kidnapping, coercion, and selling classified material, which is to say nothing of his killing of both Kohl and another officer.

How Quinn Survived Reacher Shooting Him In The Head

It's not like Reacher to make mistakes, but after shooting Quinn point blank in the forehead and watching him fall off a cliff, his assumption that the man was dead is understandable. Season 3's first episode "Persuader" explains how Quinn survived his seemingly unsurvivable fate. Reacher shot him with a smaller caliber bullet, which ended up lodging in Quinn's skull. He also survived the fall from the cliff, with the cold water he fell into giving him hypothermia.

Reacher Season 3 Had The Perfect Chance To Adapt Lee Child's "Reacher Said Nothing," But Did The Exact Opposite

Unlike its predecessors, Reacher season 3 had the opportunity to adapt Lee Child's "Reacher said nothing" rule, but it surprisingly did the opposite.

That might sound like a bad thing, but the hypothermia had the fringe benefit of slowing Quinn's heart so he didn't bleed, and the decreased oxygen prevented long-term brain damage. Quinn was eventually found washed up on a beach and went through six months of rehabilitation before disappearing again. One element Reacher makes unclear is whether Quinn re what happened to him. During his treatment, he claimed to have no memory, though doctors believe he was faking his amnesia.

Reacher shooting Quinn in the head and his subsequent fall from a cliff mirrors the plot of 1996's The Long Kiss Goodnight, where Geena Davis' ex-assassin survives a similar event.

Given how quickly he slipped back into his criminal ways, they were correct. That said, Quinn may forget the days leading up to his gunshot wound. The fact he never attempted revenge on Reacher is proof of this - though he could recognize the former 110th Special Investigator if they ever came face to face again.

Quinn's Takeover Of Beck's Rug Business & Role Explained

It appears Quinn has only gotten more violent with age. Reacher's plan in season 3 is to go undercover with rug importer Beck (Anthony Michael Hall), a suspected drug smuggler. Across the first half of the series, it's revealed Beck and his son Richard (Johnny Berchtold) are being held hostage by Quinn, who is operating under the alias Julius McCabe. Quinn had previously arranged for Richard to be kidnapped, tortured and to have his ear amputated, as a way to force Beck into handing his rug business over to him.

Quinn is using Beck's business to smuggle firearms and installs his own men Duke (Donald Sales) and the hulking Paulie (Olivier Richters) to ensure Beck always follows his commands. It's likely Quinn also kidnapped Duffy's informant Theresa, and is keeping her alive for unknown reasons. Quinn's role in the source novel Persuader is similar to season 3's first half, but the adaptation gives the villain more to do. In the same way, season 2 expanded the role of the shadowy A.M. (Ferdinand Kingsley), the third series makes Quinn less of a background threat.

For now, Paulie remains Reacher's biggest threat - in more ways than one. In Persuader, Quinn didn't fully resurface until the final chapters, but season 3 is likely to make him a more active foe, Paulie might be the muscle, but Quinn is most definitely the brains of the operation, and with his growing anger with Beck over his multiple failures, he might take a more hands-on role in future episodes.
