If you’re anything like me, you probably spent the last few months clutching a pillow and screaming at your TV because of the Cousins Beach drama. Honestly, the wait for The Summer I Turned Pretty Season 3 was brutal. But now that we’re staring down the barrel of the home stretch, everyone is losing their minds over the The Summer I Turned Pretty Season 3 Episode 10 trailer and what it means for the endgame.
First off, let’s clear up a massive misconception that’s floating around TikTok. A lot of people think Episode 10 is the series finale. It's not. Season 3 actually has 11 episodes—the longest season yet. This means Episode 10 is the "penultimate" chapter, which in TV language basically means "the part where everything goes spectacularly wrong before the resolution."
Why the Episode 10 Trailer is Stressing Everyone Out
The trailer for the final batch of episodes, which Prime Video dropped back in late August, gave us a glimpse of a version of Belly we’ve never really seen before. She’s in Paris. She’s alone. She’s wearing a trench coat and looking very main character energy while wandering near the Seine.
But here’s the kicker: she isn't just there for a vacation. This is the "Belly finds herself" arc that fans of Jenny Han’s third book, We’ll Always Have Summer, have been waiting for. In the show, the timeline is slightly different. Instead of Spain, she’s in France. And instead of going after the wedding drama is fully buried, the show has her exploring this independence while the wounds from her and Jeremiah’s almost-wedding are still pretty fresh.
The trailer for Episode 10 specifically teases a moment where Belly is sitting in a Parisian café, and she starts writing a letter. We don't see who it's to, but come on. We know. It’s Conrad. The "Bonrad" fans are basically vibrating at this point because the letters are such a huge part of the book's soul.
The Conrad in Paris Theory
There has been a ton of leaked footage and "insider" chatter about Christopher Briney (Conrad) being spotted filming in France. If the The Summer I Turned Pretty Season 3 Episode 10 trailer is any indication, we are getting a face-to-face reunion in the City of Love.

The trailer shows a quick cut of a man’s back—broad shoulders, messy hair—walking toward a bridge. Fans are 99% sure it’s Conrad. If the show stays true to the spirit of the books, Conrad has been writing to Belly for a long time while she was abroad. Episode 10 seems to be the moment those letters finally bridge the gap.
But it’s not all sunflowers and croissants.
There’s a shot in the teaser that shows Jeremiah looking absolutely devastated back at Finch. It’s a reminder that even though the wedding didn’t happen, the fallout between the brothers is still a gaping wound. Jeremiah being a "super senior" (he’s graduating a semester late in the show version) adds this layer of him being stuck while Belly is literally flying across the world.
The Big Changes from Book 3
You've probably noticed by now that Jenny Han isn't afraid to mess with her own source material. Season 3 has already introduced some wild shifts:
- Steven’s Car Accident: This wasn't in the books at all. It added a level of "life is short" stakes that pushed the wedding plot faster.
- Belly’s Career Path: She’s into sports psychology now after her volleyball injury. This makes her feel a lot more grounded and less "boy-obsessed" than her book counterpart.
- The Location: Choosing Paris over Spain for the study abroad. It’s more cinematic, sure, but it also feels like a nod to the "Sabrina" trope of a girl going to Paris to find her own worth.
What to Actually Expect in Episode 10
Based on the trailer and the way the season has been paced, here is the likely breakdown of what we’re getting.

The first half of the episode will probably be a montage of Belly’s life in Paris. We’ll see her with her new roommate, Anika (played by Sofia Bryant), and maybe even a brief cameo of her dad, John, visiting her. The show has been leaning heavily into the family dynamics this year, especially with Laurel and John’s surprising "reconnection" at the conference earlier in the season.
Then, the mood shifts. The music in the trailer goes from upbeat to that soft, pining Taylor Swift vibe we all know. This is where the letters come in.
I’m betting Episode 10 ends on a massive cliffhanger. Think: Belly walking out of her apartment, looking up, and seeing Conrad standing there. Cut to black. No dialogue. Just the sound of the Parisian street. It would be the perfect setup for the 11th and final episode to give us the "years later" epilogue we’re all dying for.
Is the Love Triangle Finally Over?
Honestly, sort of.
The The Summer I Turned Pretty Season 3 Episode 10 trailer makes it pretty clear that the "Team Jeremiah" vs. "Team Conrad" debate is reaching a conclusion. While Jeremiah and Belly clearly love each other, the show has gone out of its way to show they just aren't on the same page. Jeremiah’s "Cabo" mistake (the fling with Lacie Barone) was the beginning of the end.

Even if you’re a die-hard Jellyfish fan, the writing is on the wall. The trailer emphasizes growth over romance. Belly isn't choosing a brother; she's choosing the version of herself that is happy. It just so happens that the version of her that is happy usually has an infinity necklace hidden in her jewelry box.
How to Prepare for the Finale
If you haven't watched the Episode 10 teaser yet, go find the official Prime Video "Final Episodes" trailer. It's the one that features the "Daylight" and "Red" mashup. Pay close attention to the background of the Paris scenes. There are a few Easter eggs—like the movie posters at the cinema where Belly works—that fans think might hint at the very last scene of the series.
Actionable Next Steps for Fans
- Re-read the Epilogue: If you want to know how the books end, the last few pages of We’ll Always Have Summer are your blueprint. Just remember that the show will likely add a twist.
- Check the Episode Length: Episode 10 and 11 are rumored to be nearly an hour long each. Clear your schedule.
- Listen to the Soundtrack: Prime Video usually updates their official "TSITP" playlist a few days before the episode drops. The song choices are basically spoilers if you know how to read the lyrics.
The journey from Cousins Beach to Paris has been a long one. Whether you’re here for the romance or just the Taylor Swift needle drops, Episode 10 is going to be the emotional peak of the entire series. Keep your tissues handy. Paris is about to change everything.
