1. Loyalty Above All – Frenchie Defies Little Nina

When Little Nina tries to push Frenchie back into his old life as an assassin, he refuses to betray The Boys, showing his unshakeable loyalty. Though he's tormented by past errors, he won't make them again. This is the moment that solidifies his transformation—from a loose-cannon criminal to one who will do anything for his chosen family. In spite of the risk, he holds firm, knowing betrayal is not an option. His intense loyalty is in contrast to Butcher's cold pragmatism, proving how he's the heart of the team.
2. Saving Kimiko from the Cage - Frenchie's First Act of Kindness

The moment Frenchie recognizes her as a victim and refuses to leave her has the two perspectives (Frenchie and Butcher) clash. As Butcher was seeing a possible threat in the Asian woman, Frenchie was seeing an unnamed someone with all of the compassion and lack of self-regard that prevents him from abandoning her. It is dramatic enough when, at some point, he suddenly leaves the cage in which she is kept over with a hook. This attitude, combined with the risk he runs, makes his approach to her very significant. This releases in Kimiko not only his letting her help but even reopening the track with which a deep fellowship is orchestrated. Such a moment, in a way, also defines Frenchie in the story; he is not only a weapons specialist but also used in performing heroic acts every time he sees someone who cannot act.
3. A Moment of Joy – Frenchie and Kimiko’s Dream Dance

In one of the series' most poignant moments, Frenchie and Kimiko have a surreal musical number, a departure from the gore and brutality. It's a glimpse of his gentler side, demonstrating that he's more than a murderer. Their bond is wordless, illustrating how much they care for one another without the need for words. This montage isn't only gorgeous—it's a testament to how The Boys is not afraid to get creative with storytelling.
4. Knocking Out MM – Frenchie’s Chaotic Yet Effective Tactics

In Season 2, Episode 6 ("The Bloody Doors Off"), The Boys are on an infiltration to Sage Grove Center, and Frenchie does more than just slap MM with a chloroform-implied brush. The mission witnesses Frenchie's unfolding disorientation when Lamplighter comes into view as one of the resident operators in the facility. Crucial here is the baggage of past heartfelt failures and guilt regarding the Mallorys' family tragedy weighing down on him, thus impairing his semblance of rational fidelity. It was mostly emotions hiding more than rational thoughts, less so from Frenchie's cool than ever before. While MM takes the lead, Frenchie struggles to contain his anger, foreshadowing his explosive confrontation with Lamplighter.
5. “Mon Cœur” – The Heartfelt Bond Between Frenchie & Kimiko

The most emotional aspect of The Boys comes from the relationship between Kimiko and Frenchie. From the moment he sets eyes on her, he chooses to view her not as a weapon but as a human being. To call Kimiko "mon cœur" (my heart) is not only endearing; it is a reflection of the purpose she provides him with. He teaches her to express herself through writing, allowing her to carve her path and give her a space that is respected by him in ways that no one else has ever done. Unlike Butcher, who considers her a mere tool, or the world, which sees her as a monster, Frenchie recognizes her as family.
6. Stealth and Precision – Frenchie’s Deadly Skills in Russia

Season 3, Episode 4 ("Glorious Five-Year Plan") reveals that when The Boys go to Russia to search for Soldier Boy, Frenchie doesn't knock guards down with hand-to-hand striking but actually takes part in arms with the plan. While that is what they used to do for him, he was given real-time combat when they broke into the Russian lab, where using guns-fighting instead of close combat played a part in helping with neutralizing threats. Unlike Butcher and Hughie, however, who used temporary Compound V, Frenchie is more strategic and skilled in how he goes about things, proving that he's an extremely valuable member even without superpowers.
7. Standing His Ground – Frenchie Calls Out Butcher’s Cruelty

Frenchie has always been the team fixer, but when Butcher uses him as a throwaway tool, he finally asserts himself. "For once in your life, be human," he tells Butcher, criticizing his ruthless behavior. This is a turning point—Frenchie, who rarely confronts people, will not be disrespected. It's a character change: he's no longer merely a devoted soldier, but a man who expects respect. It also underscores the show's overall theme—how power corrupts (even among humans). Butcher can be the boss, but Frenchie tells him that respect is mutual.
8. Haunted by the Past – Frenchie’s Tragic Backstory Revealed

In Frenchie's history, there is more than one tragedy. He left his mission to save his friend from an overdose, and that turned out to be the trigger that cost Mallory's grandchildren their lives at the hands of Lamplighter. This moment makes it clear why he's so protective of Kimiko: It is, in a way, an attempt to atone for earlier failures. It is a story of redemption by proving that he is not just a reckless criminal but rather a deeply wounded man seeking forgiveness.
9. A Taste of Normalcy – Frenchie’s Passion for Cooking

In a world of such brutality, Frenchie's passion for cooking somehow stands out as an innocent trait. Cooking, whether it be the finest dishes for the team or just impatience over spice levels, expresses Frenchie's love for construction rather than destruction. It makes him human, reminding him that underneath it all, he just wants to be a normal guy. Frenchie's cooking strives to put a little homeliness into a group that never knows peace. It's a small aspect of his character that resonates deeply with the fans.
10. Trust and Revenge – Helping Kimiko Take Control of Her Fate

If Kimiko chooses to take her fate into her own hands and find those who hurt her, Frenchie will not stop her-he but will help her. Unlike someone treating her as a damsel in distress who needs protection, Frenchie respects her right to make her own decisions, and this is what makes their bond so special: his unwillingness to impose his will upon Kimiko. He is not her hero; he is her partner. This is what truly separates Frenchie from all the other guys who try to control Kimiko: he trusts her.
