Regulus enjoyed being home. Hogwarts was like home, but Grimmauld Place was his home. Even with the changes, there was something about the house that made him feel better. Maybe it was just the magic around it, or the fact that Kreacher seemed to be happier, which meant he was a lot more pleasant. He wasn't sure what it was but he enjoyed it.
He was in the sitting room, after losing Remus to the library. In the privacy of his home, he was actually with no shoes on, stretched on the couch, with his own book in his hands. When Sirius entered the room, he closed the book and put it aside.
"Of course, we can," he answered, wondering what would happen now. They did better with no people around, so maybe there was hope.
