Reacher Season 4 Ending Explained: The Finale Puts An Optimistic Spin On The Source Material

The latest season of "Reacher" wraps up today, and the finale has turned out to be just as violent and bloody as the last three seasons' conclusions. Lila (Agnez Mo) and Amisha Hoth (Anggun) aren't as terrifying as Paulie from Season 3, but they come close here. Jack Reacher (Alan Ritchson) gets himself so badly sliced up that for a moment we worried he wouldn't make it — although who are we kidding? Of course Reacher is surviving the season. "Reacher" has already been renewed for Season 5, after all. 

While much of the finale feels pretty by the books for "Reacher," the show makes a few fun choices that help it feel distinct and a lot more optimistic. Season 4 has arguably been the darkest season yet, complete with suicide bombers and grotesque torture, but its finale implies better days ahead for nearly all the characters on Reacher's side.

Fans were wondering throughout the season if presidential candidate John Sampson (Marc Blucas) is as nice a guy as he says he is. It's rare for a politician in a political thriller to not be at least a little bit evil, which is why it came as a pleasant surprise when last week's episode proved Sampson's upstanding nature in the clearest way possible: He sacrifices his life to save hundreds of civilians. 

After Sampson's death, fans speculated that his wife, Elspeth (played by "90210" actress Kathleen Robertson), might be the real evil mastermind between the two, but even that has turned out to not be the case. The finale confirms Elspeth as a noble person worthy of Reacher's respect; she may be a little cold, but she appears to have the country's best interests at heart. 

It's a far more wholesome approach than the book's. In "Gone Tomorrow," Sampson never sacrifices his life, and his final act in the novel is destroying the thumb drive and successfully hiding the image within it from the public. Sampson in the books (there named Sansom) isn't evil exactly, but he does nothing to contradict Reacher's skepticism toward politicians. The Sampsons in the show, meanwhile, force Reacher to reconsider some of his priors.

Another fun adaptive flourish of Season 4 is the addition of plucky journalist Russell Plum (Kevin Weisman), a guy motivated by his desire to expose the truth and prove his worth as a journalist. 

Instead of the flash drive being destroyed, in the show Reacher hands it over to Plum, telling him to go get that Pulitzer he's always wanted. It's a happy ending for the character, providing you believe that a mainstream news outlet would be willing to publish his findings, that the modern media landscape would reward Plum for his good work, and that the government wouldn't step in to tarnish his good name yet again to protect itself.

It's an ending that places a lot of faith in the integrity of our modern institutions, and which once again feels startlingly optimistic give how dark this season has otherwise been. Granted, maybe the takeaway here is not that Plum will get his happy ending, but that he's at least been given a chance at one. Whether his dreams work out or not is up for the viewer to decide.

The bad news: Reacher's love interest Lila has turned out to be a sadistic murderer and a terrorist. The good news: At least now Reacher doesn't have to spend the closing minutes of the season breaking things off with his new sorta-girlfriend. 

Season 4 freshens things up by letting Reacher's love interest also be the main villain; it's a choice that really streamlines this whole final section. Their break-up scene is no longer an awkward, bittersweet affair, but a cathartic fight scene that keeps viewers at the edge of their seats.

Making Lila even more unique is her knife-heavy fighting style; Jack Reacher in the books famously hates knives because they can let smaller, faster people do some real damage to him. This also makes for a more compelling, visually distinct final sequence. Reacher has always been smart, but he's rarely had to rely as much on brain over brawn as he does in this finale.

Perhaps even more optimistic than the Sampson and Plum storyline conclusions is that unseasoned police officer Jacob Merrick (Chris Marquette) survives this whole mess in one piece. Not only that, but Jacob lives without needing to resort to wanton vengeance. He arrests Amisha rather than killing her in cold blood, proving that Tamara (Sydelle Noel) was correct to trust he'd do the right thing.

Tamara also survives (although no one really doubted her on that part), and she's now fully embracing her once-forgotten ideals of being a true, high-effort police detective. It's a sweet ending, if perhaps a little familiar. Tamara and Jacob may be different from Roscoe and Finlay from Season 1 or Karla and David from Season 2, but there's a ton of overlap here. With these character arcs, it's hard not to feel like "Reacher" keeps returning to the same bag of tricks.

In yet another heartwarming moment that's not in the book, the finale shows Reacher back on the Philadelphia subway. He sees a struggling unhoused woman and silently shares half of his cheesesteak sandwich with her. It's a reminder that Jack Reacher is as much about helping good people as he is about hurting bad people.

Perhaps most importantly, the Season 4 finale ends with Reacher getting out of Philadelphia. He is once again on his way to some new location, where he'll meet a new cast of people trapped in some big conspiracy. Where is he going this time? Well, given that Season 5 is set to be an adaptation of "Make Me," it seems the next time we meet Reacher, he'll be in a small midwestern town called Mother's Rest.

Maybe it's for the best that Season 4 ends on such a bright note, because "Make Me" is one of the bleakest "Reacher" novels. If Season 5 is even a halfway faithful adaptation, it'll make most of Season 4 seem light and breezy in comparison.
