Pansy/Blaise
Pansy, after leaving Longbottom to stew in his own misery for all she cared, had circulated the party. She smiled, laughed, and generally acted as if she hadn't a care in the world. If it happened to annoy certain people, well, she was hardly in control of their emotions, was she? Eventually though, she'd had enough of the goodness and light act, and wandered outside. Noticing a certain red-head down the beach in one direction, Pansy headed in the other. She wasn't necessarily avoiding Longbottom and his close associates, but she wasn't in the mood for their brand of hypocrisy at the moment.
Once down the beach and away from the crowd, she stopped to remove her shoes. The strappy sandals did amazing things for her legs, but they weren't made for trudging through wet sand. She loved the feel of the sand beneath her feet, the way the surf lapped at her ankles as she walked, and wasn't willing to ruin the sandals just for fashion. The water was frigid, but it was a good way to clear the mind. She hated that Longbottom was able to get to her the way he was; it was humiliating and her only conciliation was that she had riled him just as much. It was also likely that Longbottom was too dim to realize the effect he had on her. At least she hoped that was true.
Lost in thought, she didn't realize she was no longer alone until someone said her name from right next to her. She jumped slightly, but relaxed when she saw that it was only Blaise. "I didn't know you were coming tonight, darling," she said, smiling at him. "I must say, you're a welcome distraction from all these Gryffindors."
