A Cat in Paris

Zoé became mute following the traumatic death of her father, which occurred when he was killed during Victor Costa's first attempt to steal the Colossus of Nairobi statue. The emotional trauma from this loss caused her to withdraw and stop speaking entirely.

Early scenes establish Zoé's silence and her distant relationship with her mother Jeanne, hinting at the deep psychological impact of her father's death.

When Lucas discovers that the fish-shaped bracelet links to Nico's address, Jeanne and Lucas rush to apprehend him. They find Nico with Zoé and jump to the conclusion that he has kidnapped her, especially since Jeanne believed Zoé was safe at home with Claudine.

Jeanne's investigation into the bracelet and Lucas's discovery of Nico's address create the误会 that leads to this accusation.

Claudine has been secretly providing Victor Costa with information about police movements, acting as his informant inside Jeanne's household. This betrayal explains how Victor's gang always seemed to know the police plans and how they were able to approach Zoé.

Claudine's seemingly attentive care for Zoé masks her true allegiances, and her secret communications with Victor's gang are revealed when Zoé discovers her at the hideout.

Dino follows Claudine's distinctive perfume scent, which leads him directly to Victor's lair where Zoé is being held. He uses this ability to guide Nico to the location, enabling the rescue operation.

Dino's keen sense of smell, established throughout the film as his tracking ability, becomes crucial in locating the kidnapped Zoé.

Zoé's voice returns after she experiences a powerful emotional breakthrough during the rescue. Being saved by her mother Jeanne, who overcame danger to protect her, helps heal the trauma that had caused her to stop speaking after her father's death.

The parallel between Jeanne saving Zoé and the inability to save her father creates the emotional resolution that allows Zoé to speak again.

Jeanne's husband was killed by Victor Costa during a previous attempt to steal the Colossus of Nairobi statue. This personal tragedy drives her obsessive pursuit of Victor and her dedication to protecting the statue during its transport.

Jeanne's briefing about the statue's security and her emotional weight when discussing it hints at the personal connection to the case.

Nico's experiences saving Zoé and working with Jeanne create genuine emotional connections that transform him. Witnessing the love between mother and daughter, and being accepted despite his criminal past, motivates him to leave his thief lifestyle and become part of their family.

Nico's initial motivation as a thief evolves as he develops care for Zoé and respect for Jeanne during their joint adventure.

After Jeanne strikes Victor during the confrontation at Notre Dame, he becomes disoriented and falls while attempting to escape. He mistakenly tries to reach what he believes is the Colossus of Nairobi but instead falls to his death.

Jeanne's determination to protect her daughter mirrors her failed attempt to save her husband, but this time she succeeds in stopping Victor.

Nico gives the fish-shaped bracelet to Dino, who then gives it to Zoé as a gift. When Jeanne finds it, Lucas connects it to the Rue Mouffetard robberies, which ultimately helps police trace Nico's identity and leads to the误会 about Zoé's kidnapping.

The bracelet serves as both a symbol of friendship between Dino and Nico, and a crucial clue that advances the investigation.

Dino lives a double life by day with Zoé and by night with Nico. The exact origin of their partnership is not detailed, but Dino accompanies Nico on jewel heists, using his small size and agility to help steal items that the burglar cannot access.

The film's opening establishes Dino's nighttime activities with Nico, showing their established working relationship.
