The Summer I Turned Pretty Season 3 Predictions Fan Theories, and That Trailer Twist!

Let’s start where it all began with Belly, fireworks, and that damn infinity pool.

When The Summer I Turned Pretty first landed on Prime Video, it brought with it a wave of nostalgia, teen angst, and Taylor Swift soundtracks that had us hooked faster than Conrad’s smirk could ruin a perfectly good day. Season 1 was soft, sun-drenched, and everything you’d want from a summer coming-of-age story. We watched Isabel “Belly” Conklin come into her own, navigate her feelings for the Fisher brothers, Conrad and Jeremiah, and face the bittersweetness of growing up, grief, and first loves. It was golden hour bottled into seven episodes.

Then came Season 2.

This time, the stakes were higher. Susannah was gone, grief hung thick in the air, and Belly was caught in an emotional ping-pong match between Conrad and Jeremiah. The easy days were over. Team Conrad vs. Team Jeremiah wasn't just a fun fandom war anymore, it was layered, messy, and very real. And while Conrad remained the broody, emotionally constipated heartthrob, Jeremiah, the golden retriever with the emotional vocabulary of a therapist. Started gaining serious ground. Belly choosing Jeremiah in the final moments of Season 2? That kiss? That drive into the sunset? It was chaos in the fandom.

Now, Season 3 is almost here, and the trailer has everyone spiraling.

Let’s talk about that trailer.

It opens with Jere and Belly being, well, very couple-y. Think sunrise dates, beach walks, and a whole lot of shirtless Jeremiah. For a show that loves a good slow burn, this felt like it was leaning hard into the honeymoon phase. But then, about halfway through, the tone shifts.

Taylor Swift’s You Are in Love starts playing, and we see Conrad. Alone. Watching. That expression on his face? Gut-wrenching. It’s the kind of scene you rewind because you’re not sure whether to scream into a pillow or text your therapist.

And then Belly says it: “I think I want to marry Jeremiah.”

Excuse me?

Let’s just pause here. The fandom didn’t even get a chance to process the beach scene before we were hit with marriage. Twitter went feral. TikTok launched into full FBI-mode breakdowns. The subreddit started looking like a crime board, red strings and all.

Here’s What the Fans Think Will Happen in Season 3:

1. Belly Will Choose Herself.

Yes, she’s saying “marry Jeremiah” now, but remember this show’s track record. Just because Belly’s with someone doesn’t mean she’s sure about it.

Shane, a TikTok fan and book reader, puts it bluntly: “Belly’s gonna crash and burn before she learns she doesn’t need either of them to be whole.”

And she might be right. Fans are predicting a major pivot, Belly realizing that all this back-and-forth isn’t healthy, and that her identity can't just be wrapped up in who she chooses.

2. The Wedding Won’t Happen.

Let’s be real. No one believes the show is about to turn into Say Yes to the Dress. Most fans think the marriage talk is a misdirect, a spark for drama. Think emotional cliffhangers and regret-filled flashbacks.
Jules from Instagram theorized: “Conrad’s going to tell her how he feels before the wedding. She’ll realize she never stopped loving him. It’s gonna be messy.”

And fans love messy. Clean lines and happy endings? That’s not what we signed up for.

3. Jeremiah Has a Secret.

There’s a whisper going around the fandom that Jeremiah might not be as squeaky-clean as he seems. Some believe he’s hiding something, something that could jeopardize his relationship with Belly.

A Tumblr user dug deep into the trailer and posted: “Did you notice Jere’s hesitation when Belly talks about marriage? He’s not ready. He’s scared.” 

If that’s true, Season 3 could be about illusions breaking down, and Belly facing the truth about what each brother represents, not just how they make her feel.

4. Conrad’s Redemption Arc.

Say what you want about Conrad, but fans haven’t given up on him. If Season 2 was about him shutting down, Season 3 might be where he grows up and finally says the right thing at the right time.

As one fan tweeted: “He’s not perfect. That’s the point. But Belly loves him. And he needs to fight for her this time.”

Many believe he’ll have a moment, probably too late, where he tells Belly that he never stopped loving her. And knowing this show, it’ll probably be raining when it happens.

5. Flashbacks Galore.

The trailer hints at a lot of introspection. Belly on the beach. Conrad in his room. Jeremiah looking unsure. This suggests flashbacks could play a big role in Season 3, especially moments we didn’t see in earlier seasons that reveal how deeply these characters have been impacted by their choices.

“Remember the rooftop scene in Season 1? That kind of raw,” said Amanda, a YouTube fan analyst. “We’re getting more of that. The quiet, heartbreaking stuff.”

Fans are bracing themselves.

But What About the Book?

Ah, yes, the book. Season 3 will be loosely based on We’ll Always Have Summer, the final installment in Jenny Han’s trilogy. If the show sticks to the book’s arc, then yes, there will be a wedding. And a breakup. And a whole lot of angst.

But here’s the thing: the show has already veered from the book in significant ways. Characters like Taylor and Steven have deeper arcs. Susannah’s death was more drawn out. And the love triangle is way less straightforward.

That means we can’t rely on the book for spoilers, but we can use it for clues.

What’s the Endgame?

Honestly? Most fans are still torn. Team Jeremiah is thriving right now, but that could change fast. Team Conrad is clinging to hope. And Team “Belly Needs Therapy” is quietly the most accurate.

But almost everyone agrees on one thing: Season 3 is going to break hearts. Whether it’s the end of Belly and Jere, the rekindling of something with Conrad, or the realization that she needs a summer without either of them, it’s going to hit hard.

The trailer didn’t show fireworks this time. It showed uncertainty. Doubt. And a whole lot of emotional whiplash.

In other words: it’s about to get very real.

So, buckle up. Whether you're here for the angst, the romance, or just Conrad's tragic ocean stares, Season 3 of The Summer I Turned Pretty is set to deliver. And if it doesn’t? Well, the fandom will let them know.

  • Belly says she wants to marry Jeremiah, but fans don’t think that wedding’s happening.
  • Conrad’s still very much in the picture, emotionally wrecked and more honest than ever.
  • Fan predictions range from “Belly chooses herself” to “Conrad crashes the wedding” to “Jeremiah might be hiding something.”
  • The show is expected to give us more flashbacks, more heartbreak, and maybe just maybe closure.

But let’s not get too hopeful. After all, this is The Summer I Turned Pretty. Happy endings are earned, not handed out with beach towels.
