I want your permission to deviate from what we agreed to in our treaty with Ephraim. I want you to grant us an exception. I want your permission to save her life. You know I’ll do it anyway, but I don’t want to break faith with you if there is any way to avoid it. We never intended to go back on our word, and we don’t do it lightly now. I want your understanding, Jacob, because you know exactly why we do this. I want the alliance between our families to survive when this is over.
Edward Cullen, Breaking Dawn, Chapter 17, p.342
