‘Lupin’ Season 3 Recap and Ending Explained: Assane’s Final Trick and Keller’s Return
The ending of ‘Lupin’ has fans revisiting the final episodes for good reason. Assane Diop navigates a whirlwind of events this season, including stealing the Black Pearl, gaining the support of the French public, faking his own death, and saving his estranged mother’s life. That’s a lot to fit into one season, even for a gentleman thief.
With the next chapter set to arrive on Netflix on October 23, it’s an ideal moment to reflect on how everything concluded. Here’s a complete recap of the events, how Assane executed his final trick, and the cliffhanger that has everyone buzzing.
The season kicks off with Assane returning to Paris for a second chance at his only failure. Back in 2017, he attempted to steal the Black Pearl, a priceless jewel from the Franco-Tahitian war, but was caught. This time, he warns the museum owner about the exact date and time of the heist, and still manages to escape.
His escape culminates in a fall from a rooftop. Everyone believes he has died, except for his sidekick Benjamin. This stunt alleviates the pressure on him and allows him to quietly protect Claire and Raoul from the media.
However, his plan faces an unexpected twist. An unknown individual contacts Assane, claiming to have his mother, Mariama, and threatens to kill her unless he steals valuable items. The kidnapper is revealed to be Keller, Assane’s former boxing coach, who spent 25 years in prison and blames Assane for it.
The finale unfolds at the Arc de Triomphe, where Keller anticipates a buyer for the pearl. Instead, he finds Assane waiting for him. Assane has also left a message for detective Guédira, indicating that he and the pearl will be present.

Assane’s offer is straightforward. He convinces Keller to hand over the pearl by promising him freedom, but it’s a double cross, leading Keller straight into the arms of Captain Sofia Belkacem. Classic Assane, delivering a satisfying conclusion for a villain who spent the season manipulating events.
The real twist comes next. Assane conceals the pearl inside a rose and hands it to a nearby woman, with Bruno later claiming it by spinning a tale about being the date who stood her up. When Guédira finally apprehends him, Assane is no longer in possession of the pearl. The ending also wraps up nicely, as Bruno and Manon sell the pearl and use the proceeds to buy back the old boxing gym in Marseille, naming it Lupin.
Assane’s mother finally reunites with her son and grandson, creating a warm family moment. Mariama even assists in retrieving incriminating evidence by disguising herself to help her son, proving she is just as clever as he is.
However, the final scenes introduce a shocking twist. The cliffhanger implies that Mariama may not be who viewers thought she was, altering the perception of every moment she shared with Assane.
Theories are already emerging, with one suggesting whether Pellegrini coerced Mariama into entrapping Assane or if he had a role in Babakar gifting young Assane his first Lupin adventure. Nothing has been confirmed, which fuels ongoing speculation.
The most significant surprise is who is orchestrating the events. The letter is sent by Hubert Pellegrini, Assane’s long-time adversary. The envelope contains a photo of young Assane holding his first Arsène Lupin novel, indicating that his enemy knows far more about Assane’s history than anyone realized.
Series creator George Kay has made his intentions clear. According to Looper, Kay states that Pellegrini will always be Assane’s archenemy, and bringing him back was part of “building the legacy of that central antagonism” in the show. This suggests that Pellegrini’s return is not just a one-time appearance.
Netflix has been cautious about revealing too much. The streamer has not provided a detailed synopsis, but Pellegrini’s return and Assane’s fate in prison could serve as a foundation for the new season. With eight episodes on the way, Ludivine Sagnier, Antoine Gouy, and Soufiane Guerrab will return alongside Omar Sy.
As the answer about Mariama looms on the horizon, do you believe she was ever truly on Assane’s side, or has Pellegrini been manipulating her since the day that first Lupin book fell into young Assane’s hands?
