Serena looked back over at Chuck with a not very hidden look of disgust on her face. "What are you talking about Chuck?" She asked as a hint of guilt flashed over her face. Serena had been beating herself up ever since she left for boarding school. She wasn't exactly sure which acts he was talking about between everything she'd done before going to boarding school it could be a number of different things. Getting too drunk and doing things with men she didn't know... Any of her time with Georgina... Nate, but she was pretty sure Chuck didn't know about that.
