The Core Trio and Returning Cousins Beach Favorites
The central drama of the series hinges on the relationship between Belly and the Fisher brothers, and the main cast members are all back to finish their characters' arcs. Their profiles are essential to understanding the final summer.
- Lola Tung as Isabel ‘Belly’ Conklin: The heart of the series, Belly faces her final choice between the two brothers. Tung, a rising star, returns to portray the emotional complexities of a young woman navigating love, loss, and growing up.
- Christopher Briney as Conrad Fisher: The older, brooding Fisher brother, Conrad’s journey this season will be heavily influenced by his past decisions and his enduring connection with Belly. Briney’s portrayal of the complicated, quiet romantic remains a fan favorite.
- Gavin Casalegno as Jeremiah ‘Jere’ Fisher: The charming, golden-retriever-like younger brother, Jeremiah’s relationship with Belly is at a critical juncture following the events of Season 2. Casalegno returns to bring Jere's bright energy and deep vulnerability to the screen.
- Jackie Chung as Laurel Park: Belly’s mother and Susannah’s best friend, Laurel’s story continues to explore themes of grief, motherhood, and her own romantic life.

- Elsie Fisher as Skye: The non-binary cousin of Conrad and Jeremiah, Skye was introduced in Season 2 and is expected to return to the Fisher family storyline.
The Emotional Returns and Notable Absences
While the main cast is confirmed, a few supporting roles have notable updates for the final season. The presence of some characters, even those who have passed away, remains vital to the story's emotional core.
- Rachel Blanchard as Susannah Fisher: Although Susannah tragically passed away from cancer in Season 2, Blanchard is often listed among the returning cast. This strongly suggests her presence will be felt through significant flashbacks, which are crucial to the final book’s narrative and the boys' emotional journeys.
- Minnie Mills as Shayla: While not officially confirmed to return, Shayla, Steven’s ex-girlfriend, remains a key entity from the earlier seasons. Her absence or return could be a surprise element in the final season's events.
- Kyra Sedgwick (Aunt Julia): A significant update for Season 3 is the confirmation that Kyra Sedgwick, who played Aunt Julia (Conrad and Jeremiah’s aunt) in Season 2, will not be returning for the final season. This suggests the storyline involving the sale of the beach house has been resolved, clearing the way for the core love triangle to take center stage.
New Faces and Potential Game-Changers in Season 3
The final season introduces a small but impactful group of new actors, whose characters are expected to introduce new conflicts or relationships as the story moves away from the immediate aftermath of Susannah’s death and focuses on the final, pivotal summer.
The new additions, while not having extensive character details released, are all confirmed to be part of the final 11-episode arc, which adapts the major plot points of *We’ll Always Have Summer*.
- Isabella Briggs as Denise: Briggs is one of the most prominent new additions, with her character, Denise, likely playing a role in the lives of the main characters, potentially at college or during the summer's central events.
- Sofia Bryant: Known for her role in *I Am Not Okay With This*, Bryant joins the cast in an undisclosed role. Fans are speculating her character could be a new romantic interest or a college friend who influences Belly or the Fisher brothers.
- Lily Donoghue: Donoghue, who has appeared in shows like *Dirty John*, is another confirmed new cast member. Her character's presence hints at new social dynamics or professional interactions outside the immediate family circle.
- Zoé de Grand’Maison: Known for her work in *Orphan Black*, Zoé de Grand’Maison's addition suggests a mature or complex new character.
- Emma Ishta: The actress from *Stitchers* is also joining the ensemble, adding another layer of intrigue to the new batch of characters.
- Tanner Zagarino: Zagarino rounds out the list of new faces. New male characters often spell trouble or new opportunities for the existing relationships in the series.
The Final Summer: Adapting We’ll Always Have Summer and Key Entities
Season 3 is a monumental event for fans as it concludes the trilogy, drawing directly from Jenny Han’s third novel. The adaptation means the cast will be tackling some of the most emotionally charged and definitive moments of the entire series.
The final 11 episodes will cover Belly's college years and the ultimate resolution of the love triangle. Key entities like the Brown University setting (where Conrad attends) and the University of Virginia (UVA) (where Belly is headed) are expected to play a major role in the backdrop of the final season, providing new environments and supporting characters for the cast to interact with.
Filming took place in North Carolina over the summer of 2024, maintaining the show’s authentic beach-town aesthetic. The showrunner has promised a faithful, yet fresh, take on the beloved book, ensuring the cast delivers the emotional payoff fans have waited years for.
The cast has expressed their deep connection to the series, with stars like Lola Tung, Christopher Briney, and Gavin Casalegno sharing their emotional goodbyes to the series that launched their careers.
