"Vampire word is law. I don't break my oaths." It's not so much noble as it is an important pillar of vampire societal norms.

"No one will take her from you. I won't tolerate it, either. She is yours to raise. But, don't you see, Tarantulas? She will suffer if you do. Her fate is tied to yours. Once she's old enough, your actions will be known to her. She will have to bear the knowledge of how she was created and carry that with her always. If you are not careful, one day, she may come to feel as betrayed by you as your friends do now. You cannot protect her from the consequences of her own birth, no matter how hard you try. That is the true tragedy of this."
