The Summer I Turned Pretty Season Finale Guide

After three years of beach vacations, loves, and losses, The Summer I Turned Pretty is coming to an end on September 17. It’s been a very special show for a lot of viewers, but also for the cast and crew. “Chris [Briney] and Gavin [Casalegno] and I were talking about this, and we were like — it’s actually really funny because it’s never as, not emotional — I always cry — but everybody had a different wrap date,” Lola Tung says in Brit + Co’s exclusive cast interview. “Some people wrapped before other people, it’s not like we all [finished filming at the same time]. Except for [the] first season, which we got very lucky. We were all at the deb ball and sort of got to have this very glamorous wrap together.”

“I cried a lot at Sean [Kaufman]’s wrap,” Jenny Han adds. “I was really sad. And then I also cried a lot at Rain’s wrap…I was literally like, tears were streaming down my cheeks at Rain’s wrap for some reason. I don’t know why. I just got really emotional.” Yeah, I’m prepared to cry my eyes out — especially since episode 10 teased Conrad and Belly are finally going to reunite without Jeremiah in the picture.

Is the finale two parts?

Prime Video

We don’t officially know how long The Summer I Turned Pretty finale is, but fans started guessing it would feature two parts when they noticed “A12” on one of the boxes in Belly’s apartment. “A12” is something Taylor Swift used to tease her upcoming album, so my guess is that we’re either in for an extended episode OR we’re getting a never-before-heard Taylor song!

Jenny Han did confirm there’s only one episode left after rumors started swirling that we’d be getting a 12th episode. “Thank you to @jenyamato and the @latimes for sitting down with me to talk about the end of the show. Just one more episode to go. Love you all!” she said on Instagram.

What happens in the finale of The Summer I Turned Pretty?

We don’t know exactly what happens (we haven’t seen it yet!) but I’m totally expecting Belly and Conrad to confess their feelings for each other and finally get the chance to be together. And the finale will probably open with Belly’s new bob and Conrad in Paris.
