The next episode of "The Summer I Turned Pretty" is now streaming. Here’s what happened in Season 3, Episode 4, from Belly’s emotional birthday to Conrad’s change of heart.

Putting her new wedding dress in her closet, Belly finds her debutante dress from the first season. She reminisces on when Susannah showed her the room for the first time, and we get a flashback of young Belly, Laurel and Susannah. Laurel had come to sleep in Belly's room when she was too scared to sleep alone.

“The Summer I Turned Pretty” Season 3 will consist of 11 episodes total with the season — and series — finale set to drop Sept. 17. After Episode 4, there will be seven episodes to go in the season. One new episode will drop each Wednesday.
