The series finale of The Summer I Turned Pretty aired on September 17, 2025, and fans are still uncovering clever Easter eggs and references tucked into the episode. From callbacks to earlier seasons to visual clues about character growth, here’s a breakdown of the subtle details that made the ending special.
Conrad’s Growth Through Gifts
In the first season, Conrad avoided giving Belly a meaningful birthday gift—the infinity necklace—because he felt unsure about his feelings. But in the finale, he gifts her a small jar of sand from Cousins Beach. This shows how much he has changed: he is no longer afraid to express his emotions or give her something personal. The sand symbolizes home and stability, something Belly cherishes .
Belly’s Hair Transformation
Belly’s new bob haircut in Paris is more than just a style change. Earlier in the season, Jeremiah asked her to keep her hair long, making her haircut a statement of independence. It represents her moving on from their relationship and making choices for herself. Conrad immediately compliments her new look, highlighting their deeper connection .
The White Matter Conversation
During Belly’s birthday dinner, her friend passes around a joint. When Belly takes it, Conrad says, “I thought you said marijuana messes with white matter.” This directly references a conversation from the first season where Belly said the same thing to Conrad. His memory of her words shows how much he values even her smallest comments .
When Belly asks if he remembers every little thing she says, he replies, “Yes.” This moment reinforces his unwavering attention to her .
The Car Window Moment
In the first season, Belly leans her head out of the car window as she arrives at Cousins, showing her excitement and feeling of safety. Throughout her relationship with Jeremiah, she never does this. But in the finale, she does it again with Conrad in the car, symbolizing that she finally feels at home with him .
The Perfect Dance
Belly and Conrad finally share a romantic dance in Paris, which contrasts with their disastrous prom night in season two. This dance represents healing and closure, as they laugh about their past mistakes and enjoy a perfect moment together .
Jeremiah’s Chocolate Cake
Jeremiah, now a chef, makes a chocolate dessert that looks similar to the two-tier dark chocolate cake with raspberry coulis he once dreamed of. This symbolizes his growth: he is pursuing his passion independently, without relying on family wealth or approval .
The Color Yellow
Throughout the season, the color yellow is associated with Conrad. In the finale, Belly wears a yellow dress, reinforcing the idea that “to Belly, Conrad is the sun.” This visual cue ties back to Laurel’s statement in season one and emphasizes their deep bond .
Benito’s Secret Photo
During Belly’s birthday dinner, her friend Benito discreetly takes a photo of Belly and Conrad sharing a sweet moment. This suggests that even side characters support their relationship, adding a layer of warmth to the scene .
Jenny Han’s Letter
At the end of the episode, Jenny Han includes a heartfelt letter thanking fans for their support. She writes, “Maybe we’ll meet again one summer in Cousins. Until then.” This has sparked speculation about future stories in the same universe, including a possible movie or spin-off .
The Full Moon Reference
When Belly and Conrad notice a full moon in Paris, Conrad says, “I like being under the same moon as you again.” This hints at a beloved scene from the books where Conrad gives Belly “the moon and the stars” on Valentine’s Day. Fans hope this moment will be explored in the upcoming movie .
Numerology Clues
Fans who love analyzing details noticed two number-related Easter eggs. When Belly checks her phone after spending the night with Conrad, the time is 4:04 a.m., and 4+4=8, which symbolizes infinity. Later, at the train station, the Brussels train display shows “5hr21,” and 5+2+1=8, again referencing infinity. These small details reinforce the idea of endless love .
