The Summer I Turned Pretty Fans Are Convinced a Surprise Bonus Episode Is Dropping After Season 3

So, about that rumored bonus episode of The Summer I Turned Pretty. I get why people were convinced it was coming, but here is where things actually landed — and why fans went into detective mode in the first place.

Spoilers for The Summer I Turned Pretty Season 3 ahead.

The short version

Season 3 officially ended with Episode 11, titled 'At Last,' which hit Prime Video on September 17, 2025. There is no Episode 12 hiding somewhere. The story wraps in that finale, full stop.

Why fans thought Episode 12 might be real

This is one of those inside-baseball cases where a few small things stacked up and made the internet think something extra was coming.

• Prime Video originally said Season 3 would run 11 episodes, but when the release schedule arrived, the last installment was labeled 'finale' instead of 'Episode 11.' That little wording tweak sent theory engines into overdrive.
• The season launched with a two-episode drop, so people figured the show might mirror that on the back end with a surprise extra on September 17.
• Fan accounts shared the 'finale' listing and asked if two episodes were dropping on the 17th — one post on September 13 even circled the label and floated the idea publicly.
• Story-wise, it felt like a lot to resolve in one hour: Belly had accepted a job in Paris, Conrad had not made his way to her yet, and Jeremiah was still working through his own mess. It did not look like a one-and-done wrap-up.

How the finale actually ties it up

Despite the speculation, Episode 11 does the heavy lifting. By the end of 'At Last,' Belly and Conrad are back together, and the show closes out its main arcs without an extra chapter. If you were holding out for a surprise drop right after the finale, that was wishful thinking, not foreshadowing.

The book math that matters

This part is pretty straightforward: the series has now adapted all three of Jenny Han's books. There is no built-in fourth novel to mine. Han has been clear about the plan from the jump:

'Three books, three seasons: it feels right to me.'

So unless the creative team decides to venture beyond the source material, Season 3 stands as an 11-episode season with no add-on Episode 12. If you saw someone say 'Season 2' in this context, that is just a slip — we are talking about Season 3.

Where to watch
