Mole in the police station: Who betrayed Kenza?

One of the most shocking turns in K.O. (2025) is when it turns out that someone inside the police force has been tampered with. The Manchour gang stays one step ahead the whole movie, which makes Kenza more suspicious that someone close to her is giving them information.
Leo's testimony, in which he says he saw a police officer work with criminals, makes this suspicion stronger. Behind bars, people called him "The Cop." At first, Kenza thinks Sarkissian is guilty because he is a close coworker who has been avoiding her since she was suspended. Things are getting more tense, especially since Sarkissian has been making bad decisions and miscommunicating a lot.
However, before she can talk to him about it, Vasseur shows himself to be the real traitor. Vasseur stabs Sarkissian to death to silence him and then turns his gun on Kenza just as she starts to piece together the truth.
Vasseur had been against Kenza during the whole investigation. His attempts to stop her lead and deny the Manchours' existence make more sense now that he looks back on them.
From the start, he was looking out for the gang and making sure they would stay alive by tainting the justice system. Vasseur threatens Kenza and Leo after telling them who he is and bragging about how far the Manchours can reach. She doesn't back down, though, and shoots him.
This action ends the threat and shows that Kenza is a moral officer. Once the mole is gone, the force can finally get back to being whole again. Even though the betrayal hurts deeply, the way it is resolved highlights the main themes of justice and sacrifice that run through the movie's final minutes.

What happens to Bastien and Kenza after the fight?

After all the violence, K.O. (2025) ends on a more peaceful note. Bastien and Kenza finally have a chance to think after being in the middle of chaos for most of the movie.
After beating the Manchour brothers and saving Leo, they stand back and watch as he starts to rebuild his life. Leo reunites with his mother Emma again by the sea, with his girlfriend Inaya walking next to him. The past is still there, but there is hope for the future.
This is the end of Bastien's story arc. He's not the same person who ran away from his guilt. Bastien changes for the better by taking care of Leo, the son of the man he killed by accident. He did more than save Leo's life; he also gave him a second chance, which was something Bastien wanted.

The Manchours' deaths end her lifelong grudge against them. The memory of her brother is finally honored, but not by getting even, but by stopping the violence that keeps happening. Bastien and she became close through fighting and being vulnerable. This makes her think about a bright future, where they might have a deeper relationship or even work together to solve crimes.

Leo starts his new life with Emma and Inaya

Leo's journey throughout the film has been defined by loss, trauma, and chaos; however, the final moments of K.O. (2025) provide a much-needed sense of closure and tranquility.
Leo has finally reached safety after being kidnapped, hunted, and betrayed. He has survived a life-threatening ordeal that could have resulted in his father's fate—a victim of violence. Rather, he is afforded the opportunity to reestablish his life with the individuals who are most important to him: his mother, Emma, and his girlfriend, Inaya.
The reunion of Leo and Emma is both quiet and profoundly emotional. Emma has endured silently since the day she lost her husband, Enzo, and has observed her son become involved in criminal activities. In her desperate attempt to locate Leo, she reached out to Bastien, whom she had previously held accountable for the dissolution of their family.
The decision she made, despite its difficulty, was the one that ultimately saved her son. Emma is granted the tranquility she has been denied for an extended period of time upon witnessing Leo's safety, vitality, and willingness to reestablish contact.

Leo's transformation is also significantly influenced by Inaya. Throughout the narrative, her presence serves as a consistent source of stability for him. Even when he is on the brink of ruin, she has faith in him. Leo is not only physically liberated while sitting by the sea, but he is also emotionally secure for the first time since Enzo's passing.
The three of them collectively establish a new family unit. Their future may be challenging, but it is no longer plagued by violence. The conclusion of K.O. (2025) is characterized by a quiet optimism: a future that is founded on healing rather than revenge.
When it comes to his preferences, his father is a private individual who seldom expresses them explicitly. Instead, he quietly derives pleasure from the happiness of those in his vicinity, prioritizing the well-being of others without raising any issue.
K.O. is currently available to stream on Netflix.
