The Summer I Turned Pretty Season 3 Cast and Main Characters
The final season brought back all the core actors and fan-favorite characters, with the main trio—Lola Tung, Christopher Briney, and Gavin Casalegno—at the center of the action. The dynamic between the brothers, Conrad Fisher and Jeremiah Fisher, and their shared love interest, Belly Conklin, was more intense than ever as the story moved into their college years at Finch University.
The complete list of returning main and recurring cast members includes:
- Lola Tung as Isabel 'Belly' Conklin
- Christopher Briney as Conrad Fisher
- Gavin Casalegno as Jeremiah Fisher
- Sean Kaufman as Steven Conklin
- Rain Spencer as Taylor (Belly’s best friend)
- Jackie Chung as Laurel Park (Belly’s mother)
- Tom Everett Scott as Adam Fisher (Conrad and Jeremiah's father)
- David Iacono as Cam (Belly's ex, who seemingly returns for a role in the college storyline)
- Summer Madison as Nicole (a returning character from Season 1)
While Susannah Fisher (Rachel Blanchard) tragically passed away in Season 2, her presence and emotional legacy continued to be a powerful entity in the final season, driving much of the brothers' and Belly's emotional arcs.
Plot Details: What Happens in the Final Season of TSITP?
The third season is a direct adaptation of *We'll Always Have Summer*, though it includes several changes to better suit the television format and the trajectory established in the first two seasons. The core of the plot revolves around Belly and Jeremiah's relationship facing immense pressure as they both attend Finch, while Conrad remains a constant, lingering presence.
The College Years and the Betrayal:
The season immediately jumps into the college environment, with Belly and Taylor enrolling at Finch. Belly is determined to make her relationship with Jeremiah work, but the cracks begin to show, particularly as the fallout from a "past betrayal" is explored. This betrayal, which is a major turning point in the source material, is a central conflict that forces Belly to re-evaluate her choices and her feelings for both brothers. The tension is palpable as the love triangle moves from the idyllic Cousins Beach to the more complicated adult world.
The Road to the Finale: Paris and Independence:
A significant portion of the season focuses on Belly’s journey toward independence. One episode, "Last Year," sets the stage for the finale with a focus on Belly's personal growth, which includes a trip to Paris. This period of separation and self-discovery is crucial, mirroring the emotional distance needed for her to finally make an informed decision, not just about which brother she wants, but about who she is as a person.
The Ultimate Ending: Who Does Belly Choose?
The 11-episode run culminated in the highly anticipated series finale on September 17, 2025. Fan theories ran wild throughout the summer, but the show ultimately stayed true to the spirit of Jenny Han's final novel. The ending provides a definitive, emotional conclusion that many book readers and "Team Conrad" fans had hoped for, while still giving "Team Jeremiah" a satisfying, albeit heartbreaking, send-off. The final episodes explore themes of true love, forgiveness, and the idea that some relationships are meant to be a summer fling, while others are built to last forever. The final moments cement the long-term future for Belly and her chosen partner, wrapping up the beloved trilogy with a mix of joy and nostalgia.
Book-to-Show Changes in the Final Season
While the show is faithful to the emotional beats of *We'll Always Have Summer*, Jenny Han and the showrunners made several notable changes to enhance the drama and pace for television.
- Steven and Taylor's Relationship Arc: The show significantly developed the relationship between Steven Conklin and Taylor, giving them a more complex and on-again/off-again storyline than in the book. Their breakup and subsequent hookups were a major subplot, adding a secondary romantic entity to the season.
- The College Setting: The transition to Finch University was a more prominent and detailed setting in the show, providing a fresh backdrop beyond Cousins Beach and allowing for the introduction of new college-life dynamics and characters.
- Expanded Character Roles: Characters like Laurel Park and Adam Fisher had more screen time, focusing on their post-Susannah lives and their roles in guiding their children through major life decisions, adding depth that goes beyond Belly's perspective.
The final season of The Summer I Turned Pretty was a massive success for Prime Video, delivering an emotional conclusion that satisfied the majority of the fanbase while providing ample material for discussion on betrayal, true love, and the cost of growing up. All 11 episodes are now available to binge-watch, allowing viewers to experience the complete journey of Belly, Conrad, and Jeremiah from start to finish.
