Final Twist Incoming: The Summer I Turned Pretty Season 3 Episode 10 Delivers a Gut Punch That Reshapes Belly’s Future

The Summer I Turned Pretty Season 3 Episode 10, aired on September 10, 2025, hits like an emotional tidal wave, culminating in a jaw-dropping twist that flips every assumption about Belly Conklin’s future. Titled “The Heartbreaking Finale,” this penultimate episode unravels the love triangle between Belly (Lola Tung), Conrad Fisher (Christopher Briney), and Jeremiah Fisher (Gavin Casalegno) with a mix of raw emotion, fractured relationships, and a game-changing revelation that sets the stage for an explosive finale in Episode 11, airing on September 17, 2025. Here’s a deep dive into the episode’s gut-punching moments, the seismic twist, and what fans can expect as the series races toward its endgame.

The Love Triangle’s Emotional Wreckage

Episode 10 dives headfirst into the fallout from Episode 9, where Jeremiah’s decision to call off his engagement to Belly—driven by her unresolved feelings for Conrad and his own past infidelity—left hearts shattered. The episode opens with Belly in Paris, grappling with the weight of her broken engagement and the lingering pull of her connection with Conrad. The Cousins Beach house, once a haven of summer memories, now serves as the backdrop for a reckoning, as the love triangle reaches its breaking point.

Conrad’s emotional confession, a moment fans on X have dubbed “peak Conrad,” lays bare his love for Belly in a way that’s both vulnerable and devastatingly late. Christopher Briney’s portrayal captures Conrad’s quiet intensity, but his history of emotional unavailability casts a shadow over his words. Meanwhile, Jeremiah’s pain is palpable, his anger and heartbreak spilling over as he confronts the reality of losing Belly. Gavin Casalegno’s performance is raw, making Jeremiah’s struggle feel achingly real. As one X user tweeted, “Jere’s heartbreak and Conrad’s confession? I’m not okay.”

Belly, caught between the brothers, is the emotional core of the episode. Lola Tung delivers a nuanced performance, portraying Belly’s turmoil as she navigates guilt, love, and self-discovery. Her decision to make a choice—without spoiling specifics, a moment symbolized by a poignant nod to Season 1—marks a turning point, showing her growth from a girl torn by indecision to a young woman reclaiming her agency. However, this choice comes at a cost, fracturing the Fisher family and leaving Belly standing in the wreckage.

The Gut-Punch Twist

Just when fans thought they had a grip on the story, Episode 10 delivers a twist that upends every assumption about Belly’s future. While The Summer I Turned Pretty has stayed rooted in Jenny Han’s book trilogy, Season 3 has taken bold creative liberties, and this twist is its most daring yet. As Vulture notes, “The show’s willingness to break from the books keeps fans on edge, and Episode 10’s twist is a game-changer.” Without diving into spoilers, the revelation involves a hidden truth about one of the brothers’ actions, reframing their role in the love triangle and forcing viewers to question everything they thought they knew.

The twist, teased in the Episode 10 trailer on YouTube, has ignited fierce debates across X. One user speculated, “That twist in Ep 10? It changes how I see [redacted] completely. Ep 11 better explain this!” Another called it “a gut punch that rewrites the whole season.” The revelation not only shifts the dynamics of the love triangle but also raises profound questions about Belly’s future—romantic, personal, and beyond. It’s a moment that demands resolution, setting up Episode 11 as the ultimate decider of the series’ endgame.

The Fisher Family’s Collapse

The emotional fallout of the twist and the love triangle’s unraveling extends beyond Belly and the brothers. The Fisher family, already fragile after Susannah’s death, faces its deepest fracture yet. Laurel (Jackie Chung) struggles to hold her family together, her scenes imbued with quiet grief as she navigates the brothers’ rift. Supporting characters like Taylor (Rain Spencer) and Steven (Sean Kaufman) also feel the impact, their friendships tested by the chaos. The Cousins Beach house, once a symbol of joy, becomes a haunting reminder of what’s been lost.

The episode’s production elevates its emotional weight. The cinematography, with its muted tones and lingering shots of the beach, mirrors the story’s somber mood. A haunting soundtrack—featuring a cover of a classic song, as noted in a TVLine recap—underscores the episode’s pivotal moments, amplifying the gut-punch effect of the twist.

What’s at Stake in Episode 11

As The Summer I Turned Pretty heads into its final episode, the twist in Episode 10 sets the stage for a finale that will determine the series’ legacy. The Episode 11 trailer, released shortly after Episode 10, hints at a resolution that balances the love triangle with Belly’s personal growth. Fan theories on X are rampant, with some predicting a romantic reconciliation—potentially tied to “Conrad’s letters from Paris,” a nod to the season’s Sabrina-inspired undertones—while others foresee a bolder ending where Belly chooses herself. One X user wrote, “Ep 11 is gonna be the ultimate test. Will Belly stick to her choice or will the twist change everything?”

Not all fans are optimistic about a satisfying conclusion. Some, like Collider, argue that the show’s heavy focus on the love triangle risks overshadowing Belly’s individual arc, potentially leaving her story unresolved. Others believe the finale will lean into the show’s emotional core, delivering a resolution that honors its themes of love, loss, and self-discovery.

Why It Hits So Hard

Episode 10 cements The Summer I Turned Pretty as a cultural phenomenon, blending nostalgia, romance, and coming-of-age drama in a way that resonates deeply. The twist’s gut-punch impact, combined with the raw performances of Tung, Briney, and Casalegno, makes the episode a standout.
