As the Season 3 finale of The Summer I Turned Pretty approaches, anticipation is reaching a fever pitch. Fans are eager to see whether Belly will finally pick Conrad, Benito or if she’ll make an unexpected choice that defies expectations. Reddit has become a hub for passionate speculation, with users sharing multiple theories about how the show might conclude.
Conrad and Belly’s Romantic Reunion
One of the most popular fan theories imagines a romantic ending for Belly and Conrad, inspired by cinematic love stories. Fans envision a heartfelt reunion in Paris, similar to Before Sunrise, where Conrad could propose spontaneously. Many speculate the finale might show the couple running into the ocean together, symbolising the renewal of their love. Some Reddit users even predict an epilogue featuring Belly and Conrad returning to Cousins Beach as a married couple, potentially with a child. This theory leans on Conrad’s long-standing emotional depth and his undeniable connection with Belly, making it a satisfying conclusion for long-time viewers.
Susannah’s Letter Brings Closure
Another theory rooted in Jenny Han’s books focuses on Susannah’s letter. Some fans believe the show will honour the book’s ending by including this poignant moment, with Belly finally reading Susannah’s words. This approach would provide a touching closure, emphasising the themes of love, family, and personal growth that have run throughout the series. Redditors point out that including the letter could tie together the narrative threads, giving fans the emotional farewell they’ve been waiting for.
Sabrina-Inspired Transformation Ending
Some viewers are drawing parallels between the finale and the classic film Sabrina. In this interpretation, Belly’s journey of self-discovery guides her to make a decision that reflects her personal growth rather than just romantic resolution. References to Sabrina scattered throughout the show give weight to this theory, suggesting the finale may prioritise her maturity and independence, while still providing romantic closure.
Belly Chooses Herself
A more contemplative Reddit theory proposes that Belly might ultimately choose herself over either of the Fisher brothers. This ending would focus on her autonomy and personal growth, highlighting her journey toward self-empowerment. Fans believe this could be the most modern and relatable ending, especially for viewers who resonate with the importance of prioritising one’s own path before committing to a relationship. While some find this open-ended resolution unsatisfying, others feel it reinforces the show’s underlying message about self-discovery and choice.
With the finale set to air on September 17, 2025, exclusively on Prime Video at 12:30 PM IST, fans will soon find out which theory or combination of theories turns out to be true. Whatever the outcome, the finale promises to deliver emotional resonance, closure, and the nostalgic summer vibes that have made TSITP a global favourite.
