1. What do you think Aro meant when he said to Caius, “Take a moment to ponder, for the justice we intended to deliver no longer applies”?
He's still trying to hold to their image of benevolent rulers, and so is looking for another, legally compelling way to bring about the conclusion he desires.
2. Were you expecting a more violent confrontation when you began the chapter?
I wasn't sure it would go that way, no. I knew that people would have to die on both sides if fighting began, and I couldn't see the Cullens getting through without a death, and I couldn't think of anyone I was prepare to lose, with the possible exception of Rosalie.
3. Do you think Caius enjoys killing or is genuinely interested in justice?
I think he's just there for the ripping and burning.
4. Were you surprised by the expansion of Bella’s talent or did you think she would have some other talent when the confrontation with the Volturi actually arrived?
I thought that it might grow a little larger when she, and more importantly, her family, were truly under threat.
5. How many different ways do you see the chapter’s title, “Bloodlust” applying to the characters and events that take place?
I think that everyone, with the possible exception of Carlisle, is lusting for blood (i.e. a fight) at this stage.
