"I don't think you'll find Emma Birch here. It's a bit earlier than she likes to come out. I don't really recommend it either, she's not the nicest ghost in the castle," Audrey explained, bending down a bit, so she was at eye level with the girl, a Gryffindor based on her robes. Audrey herself has had an encounter or two with Emma in her time at Hogwarts. Maybe it was just her, but she didn't find Emma to be all that nice. Not that Audrey could blame her, dying at sixteen with your whole life ahead of you was pretty awful. Audrey would be angry too.
