From The Grey House:
She sighed. “I don’t know who else. It was after I found out how crazy this world really was. I freed a werewolf when I was trapped in a Slayers house. The werewolf was human and in a cage. He asked for my help. I freed him, and he turned Blitzkreig and killed the Slayer. I used alcohol to bury the memory. Woke up one day with a vampire bite on my wrist. I knew then that I had to change my ways or lose myself completely.”
He gazed at her, intrigued. He did not know this story. “One day, you will tell me all your stories.”
