The O.C.’s Summer first appeared on the show as a stereotypical mean rich girl ditz – she wasn’t even a part of the main cast but instead just intended to be a glorified extra, a friend of Marissa Cooper’s with minimal impact to be essentially forgotten after the pilot. But even with the minimal screentime she got in the beginning, she quickly became a fan favorite and an integral part of the show. And over time, as her character was given room to grow, she broke free from those 'mean girl' confines and ended up getting one of the best arcs on the show. Summer is the perfect showcase of what can happen when a smart girl doesn’t have that side of herself fostered by her environment, but is instead pushed in the total opposite direction. She’s also a very underrated example of how we don’t have to be trapped in the boxes we’re put in as kids forever – and how learning to embrace our full selves can help us build a life even better than we could have ever dreamed of. So let’s take a closer look at how Summer evolved from a miserable mean girl into a successful smart girl!
