Damon had been on a binge ever since he seen his brother kiss Mandie. He didn't like it, but he would leave his brother alone for now. That didn't mean he would make it easy on him. He was on the opposite side of the room lurking in the shadows when he seen his brother walk in with Mandie. He watched as Serenity walked up to them and drug Stefan off. Once he heard what song they were playing he understood. Shaking his head he then made his move. It was dark enough in the room to not be noticed and he was very good at staying hidden. He appeared behind Mandie the instant Stefan and Serenity were gone.
