As The Summer I Turned Pretty approaches its penultimate episode, Season 3 Episode 10, the buzz surrounding the “biggest twist ever” has fans of Jenny Han’s Prime Video series on edge. With the finale looming on September 17, 2025, the trailer for Episode 10 promises a seismic shift in the love triangle between Isabel “Belly” Conklin (Lola Tung), Conrad Fisher (Christopher Briney), and Jeremiah Fisher (Gavin Casalegno). Set against the backdrop of Belly’s transformative journey in Paris, the episode teases a letter from Conrad, Jeremiah’s mysterious absence, and a pivotal decision that could redefine the series’ endgame. This article explores the trailer’s implications, the evolution of the love triangle, and what the “biggest twist” might mean, blending fan theories, book context, and the show’s bold deviations—all while keeping the mystery intact.
Belly’s Parisian Crossroads
Season 3 has taken Belly far from the familiar shores of Cousins Beach, placing her in Paris after the dramatic collapse of her wedding to Jeremiah in Episode 8. This move, a departure from the books, marks a turning point in her arc, shifting the focus from romance to self-discovery. The trailer for Episode 10 highlights Belly’s new life, with glimpses of her navigating Parisian streets, forming friendships with characters like Gemma (Corinna Brown), and grappling with her identity. A voiceover from Belly, echoing her line from the Episode 8 trailer, “I don’t even know who I am anymore,” underscores her quest to find herself outside the Fisher brothers’ orbit.
Fans have praised this shift, with a YouTube comment noting, “Belly in Paris feels like a fresh start—she’s finally growing up.” Yet, the trailer’s emphasis on a letter from Conrad suggests her past is catching up. The Paris arc, expanded beyond Jenny Han’s We’ll Always Have Summer, introduces new stakes, such as Belly missing her university enrollment deadline, hinting at consequences that could shape her future. The trailer’s vibrant Parisian visuals—cafés, cobblestone streets—contrast with the emotional weight of her decisions, setting the stage for a twist that could pivot her back toward romance or solidify her independence.
Conrad’s Letter: A Catalyst for Change
The trailer’s most gripping moment is the sound of Conrad’s voice reading, “Dear Belly…,” as she opens a letter that could alter everything. In Han’s novel, Conrad’s letters to Belly are a post-wedding gesture, written years later, that pave the way for their eventual reconciliation. The show, however, has accelerated this timeline, with Episode 9 showing Conrad’s emotional turmoil after the wedding fallout. The trailer’s focus on the letter suggests Episode 10 will reveal its contents, potentially clarifying whether Conrad is fighting for Belly or letting her go.
Fan theories on Reddit are ablaze, with one user speculating, “The letter could be Conrad confessing he’s moving on, which would be the twist—no Bonrad endgame!” Others believe it’s a declaration of love, aligning with the book’s trajectory but delivered in a new context. Christopher Briney, who plays Conrad, told People that the brothers’ dynamic is “extra brutal” this season, hinting that the letter could also address the rift with Jeremiah. The trailer’s fleeting shots of Conrad in a contemplative mood suggest he’s wrestling with his feelings, making the letter a potential turning point for both his arc and the love triangle.
Jeremiah’s Absence: A Deliberate Misdirection?
The trailer’s omission of Jeremiah has sparked intense speculation. Episode 9 painted him in a darker light, with his drunken spiral and harsh words to Belly—“Don’t ever call me again”—alienating some fans. A post on X lamented, “Jeremiah’s obsession with beating Conrad feels so out of character,” reflecting frustration with his Season 3 portrayal. The trailer’s silence on his whereabouts fuels theories: Is he in Paris, as suggested by leaked set photos from Charles de Gaulle Airport? Or is he back in Cousins, processing his grief, as seen in Episode 9 when Conrad returns to support him?
This absence could be a red herring, designed to heighten suspense for a dramatic reappearance. Alternatively, it might signal that Jeremiah’s arc is taking a backseat to focus on Belly and Conrad. A Reddit thread posits, “Maybe Jere’s twist is he steps away for good, letting Belly choose herself.” This aligns with Han’s comments to Elite Daily that the show’s ending might not require Belly to choose a brother, a significant departure from the book’s resolution.
The Love Triangle’s Endgame
The heart of The Summer I Turned Pretty has always been the love triangle, a source of both charm and frustration for fans. Season 3 has intensified this, with Belly’s engagement to Jeremiah unraveling after Conrad’s confession and long-buried secrets, like Jeremiah’s Cabo fling, coming to light. The trailer for Episode 10 keeps the triangle’s outcome ambiguous, teasing a twist that could resolve it—or upend it entirely. Han’s hint to Entertainment Weekly that “there are surprises” and “things that aren’t exactly like the books” suggests the show might diverge from the novel’s Belly-Conrad ending.
Fans are divided, with “Bonrad” supporters hopeful for a romantic reunion, while “Jelly” fans feel cheated by Jeremiah’s portrayal. A Rotten Tomatoes review captures the sentiment: “The love triangle is compelling when the characters feel balanced, but Season 3 makes Jeremiah a caricature.” The trailer’s focus on Conrad’s letter and Belly’s Parisian journey leans toward a Bonrad resolution, but the “biggest twist” could involve Belly choosing independence, a new love interest (hinted at with Fernando Cattori’s character), or an unexpected reconciliation with Jeremiah.
The Role of Family and Friendship
Beyond the romance, Season 3 has deepened the bonds between Belly, her family, and her friends. Laurel (Jackie Chung) and Taylor (Rain Spencer) play crucial roles in Episode 9, supporting Belly’s decision to go to Paris. The trailer suggests their influence will continue, with Laurel’s voiceover urging Belly to “find the person you can be.” The Fisher family dynamic, particularly the brothers’ strained relationship with their father, Adam, adds another layer. Episode 9 showed Adam stepping up, advising Conrad to give Jeremiah space, and Episode 10 might explore whether this leads to a family reconciliation.
Music as Emotional Glue
The show’s use of Taylor Swift’s music remains a hallmark, with Episode 9’s “You’re On Your Own, Kid” setting the tone for Belly’s solo journey. The trailer for Episode 10 continues this, with fans on X praising the “genius” of Swift’s songs in amplifying the drama. A potential use of “Daylight” or “Red (Taylor’s Version),” as featured in earlier trailers, could underscore the twist, whether it’s romantic or introspective. This musical thread ties the series to its nostalgic, coming-of-age roots, resonating with viewers who see their own youth in Belly’s story.
What the Twist Could Be
The “biggest twist ever” is the trailer’s boldest claim, and speculation is rampant. Possible scenarios include:
 	A New Love Interest: The introduction of a Parisian character could shift Belly’s focus, challenging the Fisher brothers’ hold on her heart.
 	Conrad’s Sacrifice: The letter might reveal Conrad stepping back, prioritizing Belly’s happiness over his own, a twist that would subvert book expectations.
 	Jeremiah’s Redemption: A surprise appearance could redeem Jeremiah, showing growth beyond his Season 3 struggles.
 	Belly’s Choice: Han’s hint that Belly might not choose either brother suggests a twist where she embraces independence, perhaps staying in Paris permanently.
Conclusion: A Finale on the Horizon
The Summer I Turned Pretty Season 3 Episode 10 is poised to deliver a twist that could redefine the series, setting the stage for the finale on September 17, 2025. With Belly in Paris, Conrad’s letter looming, and Jeremiah’s fate uncertain, the episode promises emotional highs and unexpected turns. Whether the twist aligns with the books or charts a new course, it’s clear that Belly’s journey—romantic or otherwise—will leave a lasting impact.
