She didn't know Felix Prewett too well but despite the family gossip that had resulted of his father, she knew him to be a decent man of society. Given this previous knowledge and the fact that she'd just taken tea with his mother not that long ago, she opted to not go with her first instinct of shrieking at him to get out. Instead, Diana let out an audible gasp as Mr. Prewett's head hit the roof of the carriage. "Oh, are you –" she didn't have time to complete her question seeing as he went careening towards Mrs. Wellington. It all happened so fast, and her gloved hands went to cover her mouth as Mrs. Wellington shrieked and slapped the man straight across the face.

"Mrs. Wellington!" Diana yelped, her voice filled with the exact shock that was written across her chaperone's face at what had just occurred. "Oh my goodness," Immediately she took her fan and rapped the handle against the roof. "Hello there!" she called out the window to the driver. "Please stop, sir, please!" Glancing out the window she saw that they were just driving by Hyde Park, and she rapped her fan against the roof vociferously until the carriage came to an abrupt halt.
