Draco/Regulus
As the meeting wrapped up, Draco kissed Astoria on the cheek and told her he'd catch up with her in a bit in their dormitory. He still liked getting the entire dormitory to themselves.
He made his way over to where Regulus Black was. He wouldn't really like the idea of taking instructions from someone else, but his passion was for brewing and he wasn't about to get stuck on owl droppings cleanup duty. And since he was one of the most accomplished brewers prior to Severus' return from the dead, it would be fitting.
"Ah, Regulus," he said in greeting. "I'd like to offer my services as a brewer."
