Cast and Character Profiles: Who's Returning for the Final Summer?
The core cast is confirmed to return to reprise their roles for the third and final season, which will consist of 11 episodes. The emotional weight of the series rests on the shoulders of the three leads, who will be joined by a mix of familiar faces and at least one new character to shake up the dynamics.
- Lola Tung as Isabel "Belly" Conklin: The protagonist, now a college student, who must finally choose her path and her partner.
- Christopher Briney as Conrad Fisher: The brooding, eldest Fisher brother, who has always had a complicated history with Belly.
- Gavin Casalegno as Jeremiah Fisher: The charming, younger Fisher brother, whose relationship with Belly takes a dramatic turn.
- Sean Kaufman as Steven Conklin: Belly's older brother, whose own romantic life with Taylor will face new hurdles.
- Jackie Chung as Laurel Park: Belly and Steven's mother, a writer who grapples with her own journey after Susannah's death.
- Rachel Blanchard as Susannah Fisher: Though deceased, her memory and impact continue to drive the plot and the characters' decisions.
- Kyra Sedgwick and Elsie Fisher: Their roles from Season 2, Julia and Skye, are expected to return, further exploring the Fisher family's extended drama.
- New Cast Member: Isabella Briggs as Denise: A new entity introduced in the final season, whose role is currently under wraps but is set to "shake things up."
The entire ensemble, including Belly’s best friend Taylor (Rain Spencer) and Conrad and Jeremiah’s Aunt Julia, will be back, ensuring that the final season is a true reunion of the Cousins Beach family. The dynamic between the Conklin and Fisher families remains the emotional bedrock of the series.
The Confirmed Release Date and Episode Schedule
The wait is almost over. The third and final season of *The Summer I Turned Pretty* is officially set to premiere in the summer, maintaining its tradition of a sun-soaked release. The show was filmed in North Carolina, the "Tar Heel state," which doubles as the fictional Cousins Beach.
- Premiere Date: The first episodes of Season 3 will drop on Prime Video on Wednesday, July 16.
- Episode Count: The season will feature a total of 11 episodes, a longer run than the previous two seasons, allowing for a more in-depth adaptation of the final novel.
- Release Schedule: Following the multi-episode premiere, new episodes will be released weekly on Wednesdays at 3 a.m. ET until the series finale.
This weekly release schedule ensures that the discussions and fan theories surrounding the ultimate choice—Team Conrad or Team Jeremiah—will dominate social media throughout the summer of 2026. The extended episode count is a gift to fans who want to savor every last moment of the Cousins Beach atmosphere.
The Shocking Plot Spoilers and Biggest Book Changes
Season 3 adapts the third book in Jenny Han's trilogy, *We'll Always Have Summer*, but the television adaptation is taking significant creative liberties, promising to surprise even those who have read the book. The main narrative arc focuses on Belly’s life after the intense events of Season 2 and her journey through college and into young adulthood.
The College Life and the Time Jump
Unlike the book, which featured a significant two-year time jump, the show’s transition is handled differently. Season 3 immediately establishes that Belly and her best friend Taylor have enrolled at Finch University, where Jeremiah is also a student. This move sets the stage for the initial drama, as Belly tries to process Jeremiah's "betrayal" from the end of Season 2, while he grapples with the anguish of his actions.
The Engagement and the Family Conflict
A major plot point involves Belly celebrating her 21st birthday, a key milestone that leads to a surprising development: wedding preparations. Belly and Jeremiah become engaged, but this decision is met with immediate resistance. Her family, particularly her mother Laurel, remains unconvinced about the engagement, setting up a major conflict that will test the Conklin-Fisher bond.
The Conrad and Belly Dynamic
In the original novel, Conrad gives Belly space for three years, and there is no conversation between him and Jeremiah about their relationship, at least not one Belly is aware of. The show has already deviated from this, and the final season is expected to bring Conrad back into Belly’s orbit through a different, possibly more direct, sequence of events. The final choice between the brothers is the ultimate goal, and the series is building towards a definitive "Team Conrad" or "Team Jeremiah" ending, which fans know is the "happily ever after" for one side of the love triangle.
Steven and Taylor's Relationship Status
The romance between Belly’s brother, Steven, and Taylor is a fan-favorite subplot. Season 3 confirms that the two have broken up before Belly and Taylor move to Finch. However, the season also hints that they have "hooked up across the past years," suggesting their on-again, off-again dynamic is far from over. This provides a compelling secondary romance narrative that mirrors the primary love triangle’s complexity.
The Ultimate Question: Who Does Belly Choose?
The entire series, from the first summer at Cousins Beach to the final episode, has revolved around Belly’s heart and her choice between the Fisher brothers. The third book, *We'll Always Have Summer*, provides the answer, but the show's significant deviations mean the journey to that ending will be completely unique and unpredictable. The final season’s plot, centered around an engagement and the inevitable confrontation of past hurts, is designed to make the final choice incredibly difficult for Belly and emotionally resonant for the audience.
The show's focus on the entire friend group and the family’s dynamic, rather than just the romance, adds layers of complexity. This means the ending will not just be about who Belly marries, but about her own growth and independence. Will she choose the comfort and passion of Jeremiah, or the intense, enduring connection she shares with Conrad? The 11-episode run, premiering on July 16, will finally give fans the closure they have been waiting for, settling the "Bonrad" vs. "Jere" debate once and for all.
