It’s the question that keeps every Team Jeremiah fan up at night, especially after that gut-wrenching Season 2 finale on Prime Video. If you've been following the messy, sun-drenched love triangle between Belly Conklin and the Fisher brothers, you know things are complicated. But honestly? They’re about to get a whole lot messier. To understand what happens to Jeremiah in The Summer I Turned Pretty, we have to look at two different timelines: the TV show and Jenny Han’s original book trilogy.
The show has already started planting seeds that things might go south.
Right now, Jeremiah is riding high. He finally got the girl. After years of being the "backup" or the "golden boy" who hides his pain behind a million-dollar smile, he and Belly are officially a thing. But if the show follows the blueprint of the third book, We’ll Always Have Summer, Jeremiah’s golden boy image is about to take a massive hit.
The College Years and the "Breakup"
When the story picks up for the final act, Jeremiah and Belly are a couple at Finch University. They’re happy, or at least they think they are. Jeremiah is the social butterfly, the frat guy, the life of the party. Belly is... well, she’s trying to be the person who fits into that world.
Here is the part that usually makes fans scream.
During a spring break trip to Cabo, Jeremiah and Belly have a huge fight. It’s one of those nasty ones where things are said that can’t be unsaid. They "break up"—or at least, Jeremiah thinks they did. While they are technically "off," Jeremiah hooks up with a girl named Lacie Barone.
It’s the "We were on a break!" moment of the Gen Z era.

When they get back together, Jeremiah keeps it a secret. He doesn't tell Belly. She finds out later, through the grapevine, and it absolutely destroys her. This is the turning point for his character. He goes from being the safe, sweet choice to someone who deeply betrayed her trust. To fix it? He does something even more impulsive. He proposes.
The Proposal: A Band-Aid on a Bullet Wound
Jeremiah thinks a wedding will solve everything. It’s his way of saying, "I’m committed, I promise."
Surprisingly, Belly says yes.
Most of the final arc is Jeremiah trying to prove he’s a man. He’s trying to plan a wedding while still being a kid who can’t even do his own laundry. It’s painful to watch. He’s living in a suite with Conrad nearby, and the tension is thick enough to cut with a knife. He’s constantly looking over his shoulder, wondering if Conrad is going to swoop in.
He’s insecure. Can you blame him? He’s spent his whole life in Conrad’s shadow, and he knows deep down that Belly’s connection to his brother hasn't just evaporated into thin air.
During the wedding preparations at the summer house, Jeremiah finds out the truth. He realizes that Conrad told Belly he loved her. Even worse, he realizes that Belly is still affected by it. There’s a scene in the book where Jeremiah sees how Belly looks at a necklace—the infinity scarf/necklace symbolism—and he knows.

The Ending: Does Jeremiah Get the Girl?
In the books, the answer is a hard no.
On their actual wedding day, Jeremiah realizes he can’t go through with it. He knows he isn't the one she truly wants in her bones. They have a heart-to-heart, and they call it off. It’s tragic, but it’s also the first time Jeremiah actually grows up. He stops trying to win a competition and starts looking at the reality of their relationship.
He eventually finds his own path.
Years later, at Belly and Conrad’s wedding (yeah, that happens), Jeremiah shows up with a date. He’s happy. He’s moved on. The rift between the brothers starts to heal, which is honestly the most important part of his journey. He loses the girl, but he regains his brother and his sense of self.
How the Show Might Change Things
Jenny Han is a producer on the show, and she’s known for tweaking things for the screen. In the books, Jeremiah’s "cheating" is a bit more black-and-white. In the show, they’ve made Jeremiah much more observant and sensitive.
Fans are speculating that the Cabo plotline might be changed. Why? Because the TV version of Jeremiah is arguably more likable than the book version. Making him a "cheater" might feel out of character for the guy who stayed by his mom’s side every single day while she was sick.

However, the show needs conflict.
Whether it's a physical betrayal or just a massive emotional disconnect, what happens to Jeremiah in The Summer I Turned Pretty will likely involve him realizing that being the "rebound" isn't enough. He deserves to be someone’s first choice, not just the guy who was there when the other brother messed up.
Key Takeaways for Jeremiah’s Future
If you want to prepare for the final season, keep these points in mind:
- The Cabo Trip: Watch for any mention of spring break or a girl named Lacie. That’s the red flag.
- The Insecurity Factor: Jeremiah’s arc is defined by his rivalry with Conrad. Watch how he reacts whenever Conrad is mentioned; it’s the key to his downfall.
- The Growth: Jeremiah’s "win" isn't marrying Belly. It’s becoming his own person outside of the "Fisher Brothers" dynamic.
- The Mother’s Legacy: Everything Jeremiah does is filtered through the loss of Susannah. He’s trying to hold onto the summer house and the memories, which often clouds his judgment.
The best way to stay ahead of the curve is to re-watch Season 2 and look at the "choice" Belly makes. She chose Jeremiah because it was easy and fun, while Conrad was difficult and heavy. But real life—and real marriage—is heavy. Jeremiah is about to learn that the hard way.
Keep an eye on the official Prime Video social channels for Season 3 production updates, as filming delays have shifted the timeline, but the core of Jeremiah’s struggle will remain the centerpiece of the upcoming episodes. Focusing on his character growth rather than just the romance gives a much clearer picture of where this story is headed.
