Severus + Regulus
Regulus smiled. He appreciated sarcasm. "It is rather shiny in here and the lights don't help, but since I like to be the bright and shining light in a room, this suits me." He opened his arms, holding the lower part of his robe to show off the decoration. "Isn't it wonderful? I had it custom made."
This was the part he has missed while in hiding: showing off. "I'm well, thank you. I love parties. I get to meet so many people." And his house elf would learn all sorts of secrets that he could use later. "Ready for the start of the school year? I admit that I'm surprised that you would choose that career. I know how much you love children."
