Tessa Rose doesn't believe in anything. She doesn't believe in God, or fate, or destiny. There is only one thing she believes in as a solid thing she can grasp. And that is death. She has seen death her entire life and she knows its there. She knows that he's there. She has seen death in his human form, and when he asks her to be his apprentice she finally feels like she has purpose. Not a purpose in life. But a purpose with Death.
