"I like you, as ridiculous as that is. I am upset that you're upset and I want to help. Vampires can form meaningful personal connections, we just usually don't with humans because most of us think of you as ambulatory juiceboxes. I was never going to kill you, and while I'm at it I also don't mean to kill anyone else in this town, or on this planet, or ever again if I can help it. Is that enough truth for you or would you like some more?"
