The Summer I Turned Pretty Season 3: The Biggest Changes From the Book

No Rebrand For Belly Conklin

Before Belly opens her dorm room ahead of her freshman year—a flashback that takes place in the first five minutes of the season premiere—her brother Steven Conklin (Sean Kaufman) quickly scribbled “Belly” over her full name, “Isabel,” on the door. In subsequent scenes, her college friend Anika Johnson (Sofia Bryant) calls her Belly.

However, in the book, Belly didn’t correct anyone who called her by her government name.

“I didn’t plan to start going by Isabel. It just happened,” she said in the book. “I remember the way I fumbled with my key and how I looked up at the door and saw it. ‘Isabel,’ it was in glue-on rhinestones.”

Then, she introduced herself as Isabel to her roommate Jillian Chapel and moving forward, it’s what everyone at Finch called her.
