Severus + Regulus
Regulus loved the fashion of the day. It was bright and in your face and spoke to his sense of being noticed. He had picked a robe that was a shiny pin strip grey with pink stars and moons. Its shoulder were wide and the V neck line open down to his mid chest. Modest, he was not.
Walking around, he saw Severus Snape. They had talked at the dinner at Narcissa's, but there was only so much one could say with Lucius around. Regulus liked a more personal approach, especially when Severus was close to Dumbledore and information was always useful.
"Severus, so nice to see you after all this time," he said as he approached the man. "How are you?"
