Claire and Raoul hide from Keller in a closet. Thinking quickly, Claire manages to trick Keller by making a call to her home phone, suggesting that neither she nor Raoul is there. The following morning, Claire calls Assane, reveals that she knows that he and "Alex" are the same person, and begs him to come and pick her and Raoul up. When Assane arrives at Claire's and Raoul's apartment, all three share a happy reunion, before Assane brings them to his hideout, where they meet their mother-in-law and grandmother for the first time.
Claire wants to take the path of least resistance by hiring a lawyer for Benjamin and fleeing to a safe house in the countryside, but Assane still desires to take down Keller. Without telling Claire and Raoul, he and Mariama infiltrate an event being thrown by the minister for the interior and break into his office, where they gain enough information on him to blackmail him into releasing Manon from jail. When Manon gets out, Assane accosts her and tells her the truth of how Keller and Bruno had manipulated him. With the pedestal she'd placed Keller on decidedly broken, Manon agrees to double-cross Keller. At Assane's behest, she calls him and relays a message instructing him that she's found a buyer for the black pearl, whom he'll meet on top of the Arc de Triomphe that evening.
When Keller arrives, however, the person awaiting him is Assane. When Keller realizes that he's been set up, he makes a break for the exits, but is immediately blocked by Guédira, Belkacem, and a host of other officers (earlier that evening, Assane had relayed a coded message to Guédira informing him of the location). While Belkacem handcuffs Keller, Guédira goes looking for Assane, and is shocked to find him waiting with his arms outstretched, ready to make good on his earlier promise to allow himself to be taken into custody, on the conditions that Guédira will provide him with the entire collection of Lupin books in his prison cell, that he'll release Benjamin, and that he'll give him a message to deliver to Claire.
The following morning, Claire arrives at the train station previously specified by Assane, anxiously waiting for him to arrive. However, she, Raoul, and Mariama are met by Benjamin, who gives Claire Assane's letter, in which Assane explains that he felt that the only way she and Raoul could truly be free would be for him to turn himself in. Claire is devastated and falls into Benjamin's arms as he looks back towards Raoul and Mariama with a grim Thousand-Yard Stare.
Assane, meanwhile, is just getting used to life in prison, when a guard delivers him a package sent by an inmate in a cell nearby—a photograph of himself as a boy, holding a Lupin book. Guess who the generous inmate is? Yup—it's none other than Hubert Pellegrini.
Episode credits:
Tropes that appear in this episode:
- Ambiguous Ending: The ending has Assane reading a passage from an Arsène Lupin book, which indicates that someone in his inner circle has betrayed him. The voiceover transitions from Assane's voice to Mariama's to Hubert Pellegrini's, accompanied by closeups on the faces of Mariama, Benjamin, Juliette, and finally Hubert.
- Big Damn Reunion: Two in quick succession: first, when Assane comes to pick Claire and Raoul up from their apartment, not in disguise as Coach Alex but as himself, and immediately afterwards when he brings them both to his hideout and introduces them to Mariama.
- Big Damn Kiss: Between teenaged Assane and Claire during the final flashback sequence in Part 3, when they meet at the Gare de l'Est while preparing to run off together.
- The Bus Came Back: Hubert Pellegrini is back on the scene. Part 3 concludes with the Cliffhanger of Assane coming to this realization after his "neighbor" sends him an envelope containing a photograph of himself as a teenager.
- Call-Back: Assane's final letter to Claire references her telling him, in the first episode of Part 3, that the only way he'd be able to repay her and Raoul would be to turn himself in. Of course, by that point, Claire doesn't want him to hand himself over at all (and even her initial statement comes across more like it was just her venting her frustrations, rather than any real desire for him to do so).
- Corrupt Politician: Thierry Floron, the minister for the interior. Assane and Mariama blackmail him into letting Manon out of jail. He's also the one who forced Hubert Pellegrini's release from custody in Part 2.
- Cry into Chest: Claire collapses into Benjamin's arms after she reads Assane's letter.
- Eye Take: The final shot of the episode is a closeup on Assane's face with his eyes bugging out as he becomes aware of whom he's been placed next to in prison.
- Fauxreigner: Assane's military colonel persona, "Ali Abdelkarim," is intended to be from the African nation of Chad.
- Final Battle: Assane, with the help of Bruno, gets Keller sent off to jail.
- I Gave My Word: Assane ultimately stands by his earlier promise to allow Guédira to arrest him.
- Have I Mentioned I Am Gay?: In order to sneak the black pearl out of the Arc de Triomphe, Assane hides it inside a rose, which he gives to a tourist, claiming that he's been Stood Up by his date. As the tourist is leaving she's accosted by Bruno, who tells her that he's the date and asks for the rose so that he can give it back when he sees his "boyfriend" again.
- Heel–Face Turn: Manon agrees to help Assane trap Keller after he tells her the full story of Keller forcing him and Bruno to rob the jewelry store when they were teenagers.
- Hope Spot: By now, anyone watching this show should be well aware that Assane isn't going to ride off into the sunset with his family, no matter how much it seems like he will.
- Luxury Prison Suite: Downplayed for Assane's. It's got the collection of Lupin books that he requested, but it's still quite cramped, although—unlike his earlier spell in prison in Part 1—at least he gets to be alone in it.
- Noble Bigot: The colonel who gets Assane into Floron's event has aspects of this. He's casually racist and homophobic, but ultimately he seems to respect Assane on an individual level at least.
- Obfuscating Stupidity: At the gala held by the Thierry Floron, Mariama pretends to be a clumsy, inept waitress, creating a distraction by spilling a tray of drinks on the floor so that Assane can get into Floron's office.
- Pensieve Flashback: When Claire, along with Raoul and Mariama, is waiting for Assane at the train station, she appears to watch her teenage self meet up with Assane at the same location twenty-three years earlier.
- Phoney Call: How Claire throws Keller off of her trail—while hiding in a closet with Raoul, she uses her cell phone to call her landline and leaves a message implying that neither she nor Raoul are home, and that Raoul's (fictional) uncle, who is a police officer, will be along momentarily. Upon hearing this, Keller leaves.
- I Want My Beloved to Be Happy: Assane's rationale for turning himself in is that if he does so, the world will eventually forget about him, allowing Claire and Raoul to live their lives in safety.
