Olly actually knew her story. His daddies had told him and his siblings at least once before. It was interesting, but did not necessarily make for a good bedtime story. The Bloody Baron killing her before taking his own life. Not exactly cheerful.

And there was the Baron himself. Olly grinned at the ghost and waved. He was the Slytherin ghost, and so Olly had to like him the best. Even if he did look a little scary. And the story of his death was not exactly cheerful. But whose death was cheerful?

He raised his hand to ask the Grey Lady a question. She had not really asked for them, but she had paused and it seemed like a good opportunity. Besides, others were asking questions. He figured it was okay. "What name do you prefer to be called?" It was always important to call someone the name they preferred, of course. He would not want to offend anyone, not even a ghost.
