The Worst Things Jeremiah Fisher Does On 'The Summer I Turned Pretty'—A Ranking You Can't Miss!
Every story needs a villain, and on Amazon Prime's 'The Summer I Turned Pretty,' Jeremiah Fisher is the most unforgettable antagonist you'll ever meet. Played by Gavin Casalegno, the younger brother of Conrad (Christopher Briney) and son of Susannah (Rachel Blanchard) and Adam (Tom Everett Scott), Jeremiah isn't a villain in the traditional sense—he’s just a spoiled kid who never gets a good reason to grow up. Author Jenny Han, who also penned the bestselling novels of 'To All the Boys I've Loved Before,' served as showrunner for the series, and the show’s chaotic charm is partly due to its flawed yet lovable protagonist.
Jeremiah’s flaws are hard to ignore, even when his actions aren’t outright malicious. He’s a decent kid who loves his mom, family, and friends, and many of his decisions throughout three seasons are actually well-intentioned. His relationship with Isabel 'Belly' Conklin, a quirky character with a bizarre nickname, is full of heartwarming moments. Belly, whose mother Laurel Park (Jackie Chung) takes the town of Cousins Beach every summer, is a sister figure to Conrad and Jeremiah before she ‘turns pretty’—a term that means she loses her braces. But Jeremiah’s antics often clash with Belly’s idealism, especially when he tries to win her over with reckless behavior.
Despite his good intentions, Jeremiah’s actions frequently backfire. One of the most controversial moments occurs when he breaks up with Belly before her spring break trip to Cabo. At the end of season 2, Belly visits Finch College, her grades slipping so low that she’s left with no choice but to apply there. Meanwhile, Jeremiah, still nursing a grief over his mother’s cancer, abruptly ends their relationship. By the time he ‘breaks up’ with Belly, there’s no excuse left—she’s been mourning her mom for years. The fallout is brutal: he cancels their trip, throws a tantrum over a wedding cake he didn’t ask for, and later proposes to Belly in a way that feels embarrassingly rushed. The whole thing culminates in a disastrous Cabo trip where he accidentally gifts her a puka shell bracelet, a gesture that feels more like a joke than a sincere apology.
Another major controversy arises when Jeremiah changes the wedding plan without Belly’s consent. He spends weeks in Boston working for his dad Adam (Tom Everett Scott) at his “business,” leaving Belly to plan the wedding alone. Even after she tells him the cost of a two-tier chocolate cake with a raspberry coulis filling, he insists on paying for it anyway. When Belly can’t afford it, he offers to pay at his stuffy country club, ignoring her input. The result? A heartbreaking betrayal that leaves Belly feeling betrayed, even as she hides her disappointment. The wedding never happens, and Jeremiah’s hasty decision becomes a cautionary tale about poor communication.
Jeremiah’s most infamous moment comes when he sets off fireworks to interrupt Belly and Conrad’s first kiss during a July 4th party. This bratty move, which occurs halfway through the first season, is fueled by his jealousy over Conrad and Belly’s growing relationship. Even though he’s young and immature, his actions are glaringly out of line. While Belly and Conrad eventually reconcile, this interference creates a rift in their dynamic. The incident is especially painful because Jeremiah’s own behavior—like confessing to cheating on Belly with Lacie Barone—mirrors his toxic patterns.
The final chapter sees Jeremiah try to redeem himself, but his infidelity with Lacie Barone during a spring break trip remains unforgivable. He sneaks into Belly’s life, steals her heart, and later betrays her with a friend. The fallout is devastating: Conrad, who had no idea Jeremiah had ever left Belly, confronts Belly on the beach, leading to a betrayal that shatters her trust. The show ends with a bittersweet note, as Jeremiah’s mistakes haunt the characters, but the legacy of his actions lingers.
If you’ve already binged the series, consider exploring other shows like 'The Summer I Turned Pretty' on Amazon Prime, where the chaos of high school drama meets the unpredictability of teenage romance. But here's where it gets controversial... What if Jeremiah had chosen a different path? Could he have grown up, or would his flaws have always defined him?
