Ashley had a game plan, and it was simple and straightforward. She had done a brief background check on the one that stole her demon from her. Apparently, she was a known exorcist in the field of exorcism, which was a terrible taste for someone like Azrael, the King of Hell.
She was everything he stood against. A low-life demon catcher and a major foe to the great kingdom of Hell. She wasn't really sure if Azrael knew who his bride was—revealing who she was to him could later be useful. Who knows, the witch could have spelled him not to make that part of her life visible to him, or Azrael wouldn't just care.
