The Summer I Turned Pretty Season 3: Cast & Character Profiles

To establish topical authority, here is a quick look at the main stars who brought Belly, Conrad, and Jeremiah to life one last time.

- Christopher Briney (Conrad Fisher): Born in Danbury, Connecticut, Christopher Briney (born March 24, 1998) is known for his brooding, intellectual portrayal of the elder Fisher brother, Conrad. Beyond his role in *TSITP*, Briney also starred in the 2024 musical film *Mean Girls*, showcasing his range as an actor.

The Final Summer: Belly's Choice and the Conclusion (Spoilers)
The central question of the entire series—who will Belly choose: Conrad or Jeremiah?—was finally answered in the Season 3 finale. This highly anticipated ending followed the narrative of Jenny Han's final novel, providing a satisfying conclusion for fans of the 'Team Conrad' camp.
The season heavily focused on the breakdown of Belly and Jeremiah’s relationship, which had been strained since the events of the previous summer. The drama escalated with the introduction of the infamous "wedding plot" from the book, which was the final catalyst for Belly's realization about her true feelings.
The Tumultuous Journey to the End
The 11 episodes charted a course filled with emotional highs and lows. The early episodes, titled "Last Season" and "Last Christmas," set the stage by exploring a significant time jump and the new dynamics between the characters, including a look at Susannah's past and the Fisher family's enduring legacy.
The tension between the brothers, often referred to by fans as the "Conrad vs Jeremiah" debate, reached its peak as Belly had to confront her feelings for both. The series creator, Jenny Han, has always maintained that the show would follow the books' ending, which meant Belly ultimately chose Conrad Fisher.
The Finale Explained: "Last Summer"
The series finale, "Last Summer," aired on September 17, 2025. It concluded the love triangle with Belly and Conrad reuniting. Their final moments together—often involving a romantic walk, a kiss, and a shared night—were a direct adaptation of the book's resolution.
While the ending was bittersweet for "Team Jeremiah" supporters, it provided closure for Belly's arc, confirming that her first love, Conrad, was her final choice. The entire season is a masterclass in adapting a beloved young adult novel, ensuring all plot points, including the dramatic wedding and the ultimate choice, were covered in detail across the 11-episode run.
Now that the complete season is available, it’s the perfect time to revisit Cousins Beach and experience the full story of Belly, Conrad, and Jeremiah from start to finish on Prime Video.
