"It's less fighting the concepts and more..." Her voice trails off as she thinks about it. She's never had to actually explain darkness and light to anyone before. They were just understood. "Darkness can manifest in a physical form, but not always. I once met a young woman who was so kind and compassionate. It shined out of her in everything she did. Her step mother and step sisters grew jealous and their jealousy of her created a creature of darkness. That's what I fight. To defeat that creature of darkness and protect the young woman. Sometimes we'll be able to change the jealousy into something else. That's what I do."

Sometimes kicking someone until they see the error of their ways works.
