"Didn't think you had," he says quietly, fingers curling down to Kieren's nape. "I just think this place has a terrible sense of irony and poor methods of lesson-learning. Not to mention this is a terrible place for a gravestone. It's just rife for vandalism here. I should know, really."

Though Sirius can at least put a spell on if it he needs to protect it from just such a thing. And he will, he thinks. Whether Kieren knows of it or not.
