Summer’s heat is about to hit theaters like a tidal wave—leaked script pages from The Summer I Turned Pretty movie just spilled Belly’s ultimate endgame, but one Fisher brother’s shocking sacrifice could rewrite the love triangle forever. Jenny Han’s directing this bombshell, and fans are rioting: Conrad’s vow or Jeremiah’s vow? A hidden letter from Susannah changes it ALL. Click before the Cousins Beach secrets wash away.
The internet is on fire right now, and for good reason. Just days ago, shadowy screenshots of alleged script pages from the upcoming The Summer I Turned Pretty: The Movie began circulating on TikTok, Reddit, and private fan Discords like wildfire. These aren’t your average spoilers—these fragments appear to reveal the heart-stopping climax of Belly Conklin’s decades-long love story, and they’re tearing the fandom in two. Belly’s final choice? A vow that could seal her future forever. But it’s not just about who she picks; it’s the jaw-dropping sacrifice one Fisher brother makes that might flip the entire narrative on its head. And at the center of it all? A long-buried letter from Susannah Fisher herself, the woman whose memory has haunted every summer in Cousins Beach.
With Jenny Han herself stepping behind the camera to direct this final chapter—confirmed after the emotional Season 3 finale last September—the stakes have never been higher. Prime Video’s announcement of the movie as the “true conclusion” to Belly’s journey already had fans screaming. Now, with these leaks dropping in mid-February 2026, just as whispers of filming prep in North Carolina swirl, the anticipation is unbearable. Summer may be months away, but the heat is already scorching.
Let’s set the scene for those who’ve been living under a rock (or perhaps wisely avoiding spoilers until now). The Summer I Turned Pretty, adapted from Jenny Han’s bestselling trilogy, has captivated millions since its Prime Video debut. The story follows Isabel “Belly” Conklin (Lola Tung), who grows up spending magical summers at Cousins Beach with her mother Laurel, brother Steven, and the Fisher family—especially the two magnetic brothers: brooding, intense Conrad (Christopher Briney) and sunny, charming Jeremiah (Gavin Casalegno). What begins as innocent childhood crushes explodes into a full-blown love triangle that spans years, heartbreaks, engagements, breakups, and endless yearning.
Season 3, which wrapped in September 2025, left viewers reeling. After Belly’s rollercoaster with Jeremiah—including a dramatic engagement that echoed the books but veered into new emotional territory—the finale saw her reunite with Conrad in a tender, train-bound moment that felt like destiny. Conrad flew to Paris (yes, Paris!), where Belly was studying abroad, and the two finally acknowledged what fans had screamed about for years: they were endgame. Jeremiah, heartbroken but growing, found solace with new love interest Denise. It seemed resolved. Conrad and Belly, together at last.
But Jenny Han had other plans. In interviews following the finale, she teased that the movie would deliver “one big milestone left in Belly’s journey,” something only a feature film could capture properly. No quick wedding montage here—this is meant to be epic, emotional, and definitive. And now, those leaked pages suggest it’s going to deliver in ways no one saw coming.
The alleged leaks—grainy phone photos of script excerpts stamped with production watermarks—focus on what appears to be the film’s third act. In one pivotal scene, Belly stands on the beach at Cousins, the same stretch of sand where she first “turned pretty” all those years ago. She’s older now, mid-20s, wearing a flowing white dress that catches the ocean breeze. Conrad is there, eyes locked on hers, ready to make a vow that echoes the promises they’ve broken and remade. But then Jeremiah appears—not as an antagonist, but as someone who has carried a secret burden for years.
The bombshell? Jeremiah has been holding onto a letter from Susannah, written before her death but never delivered until this moment. In the leaked dialogue, Susannah writes directly to Belly: words of love, forgiveness, and a quiet plea. She confesses that she always saw the depth of Conrad’s feelings but also knew Jeremiah’s heart was pure sunshine—the kind Belly needed to heal after grief. Yet the letter ends with Susannah’s ultimate wish: for Belly to choose the love that makes her feel most alive, even if it hurts. “Don’t settle for safe, my girl,” the line reportedly reads. “Choose the storm if it means you’ll dance in the rain.”
This revelation shatters something in Jeremiah. In the pages, he doesn’t fight for Belly; instead, he makes the ultimate sacrifice. He steps back—permanently. Not out of bitterness, but out of love. He tells Belly he’s releasing her, that he’s found his own path (perhaps with Denise, perhaps alone), and that watching her with Conrad has shown him what real, enduring love looks like. The moment is devastating: Jeremiah kisses Belly’s forehead one last time, whispers “You were always my summer,” and walks away down the beach as the sun sets. Fans are calling it the most selfless act in the entire series—a brother choosing his sibling’s happiness over his own heart.
But here’s where the rioting begins: Is this truly Belly’s endgame with Conrad, or is the letter a red herring designed to test loyalties one final time? Some leaked lines hint at doubt. Belly hesitates during the vow exchange, her hand trembling as she looks toward the horizon where Jeremiah disappeared. Conrad, ever the stoic one, notices and says, “If it’s not me, Belly… if it’s ever him… I’ll let you go. But I need to hear it from you.” The tension is palpable. Will she say “I do” to Conrad, honoring the storm Susannah described? Or does the letter awaken something unresolved, pulling her back toward Jeremiah’s light?
The fandom is divided like never before. Team Conrad (long the book-endgame) is triumphant, pointing to the Paris reunion and the trilogy’s trajectory. Team Jeremiah—affectionately “Jellyshippers”—is heartbroken but also fiercely protective of Gavin Casalegno’s portrayal, arguing that Jeremiah’s growth deserves its own happy ending, not just sacrifice. Social media is flooded with edits, petitions, and tearful reaction videos. One viral TikTok stitches the leaked pages with footage from Season 3’s finale, captioning it: “Jenny Han said she’d surprise us… and she DID. Jeremiah’s sacrifice >>> everything.”
What makes these leaks so explosive is their authenticity vibe. Details match known production intel: Jenny Han directing, filming potentially starting soon in North Carolina (Cousins Beach locations), returning cast including Lola Tung, Christopher Briney, and Gavin Casalegno. Even minor elements—like references to Belly’s time in Paris, Steven and Taylor’s budding future, and the ever-present house at Cousins—align perfectly. While Prime Video and Han haven’t commented (classic spoiler lockdown), the silence only fuels the frenzy.
Imagine the big screen: sweeping drone shots over the Atlantic, golden-hour lighting on the beach, Hans Zimmer-esque strings swelling as Belly makes her choice. Jenny Han’s directorial eye—honed through seasons of intimate, character-driven moments—promises visuals that will make every tear fall harder. This isn’t just a rom-com wrap-up; it’s a full-circle reckoning with grief, growth, and the messy beauty of first loves that linger.
Yet questions remain. Will the movie stay true to the books’ Conrad endgame, or has Han rewritten history for the screen? Does Jeremiah’s sacrifice lead to his own spin-off dreams (fans are already begging), or is it the bittersweet close he deserves? And that letter—real or cinematic invention? Susannah’s voice has always been the emotional core; bringing her back via words feels poetic, profound, devastating.
As February 17, 2026 ticks by, the leaks remind us why this story endures. It’s not just about who Belly chooses; it’s about the summers that shape us, the people who break and heal our hearts, and the courage to choose love even when it terrifies us. Whether Conrad’s storm or Jeremiah’s sunshine wins, one thing is clear: this movie will leave no heart untouched.
So grab the tissues, mark your beach reads, and brace yourself. Summer’s heat is coming to theaters, and it’s going to hit like a tidal wave. The Cousins Beach secrets are washing ashore—don’t look away now.
