1. Why do think the Volutri have been in power for so many years? What makes them so powerful? Why hasn’t any other vampire coven challenged the Volturi thus far? Why now?
They are the largest coven and They collect others with powerfull gifts that would aid them if needed, and most see it as a high honer to be chosen by them. No other coven is challengeing them for "power" the Volturi only assume that the Cullens is a threat to their "power".
2. If you were part of a vampire coven that Carlisle has called upon for help, would you join the Cullens? Why or why not?
Yes I would join the Cullens. If you were called upon for help by Carlisle that would mean you knew him at some point in your life knew what kind of person he is and the old saying.. a family member of Carlisles would be a friend of mine, so to me there would be not hesation no matter who, how powerfull,and what they needed helped with...yep..well at least ya died with your boots on helpin a good family.
3. Amun and Carlisle have both created vampires. What makes these two characters different?
Carlisle did it because of eatch of them was near death, out of compassion, love and a touch of loneyness he would never just change someone to just be changing them. Amun did it selfishly because he know Benj..would be a powerfull vampire.
4. Why does Edward downplay the seriousness of being a war with the Volturi?
He hopes and knows the Volturis thinks and are afraid that the Cullens are more powerfull and to see all the witnesses it would make them pause long enough, but mostly so Bella and Nessie wont be too scared even tho Bella already is.
5. Were you surprised on how Renesmee’s and Bella’s interact with another? Why or why not?
No not realy surprised, Bella already proved she's die for Renesmee after that keeping her safe an happy is all that matters, of course how they interract would be differnt from normal mother daughter relationships, Renesmee is a mix of Bella an Edward so of course Nessie is special and very smart so they have fun togather and they are serouse at the sametime they can explain stuff that you would not explain to a child much less a baby/toddler.
6. Do you think Bella and Charlie’s relationship has changed? Why or why not?
Yes Bella isn't a child anymore and they share a deep secart that they cant even share with her mother. Like any parent child relationship it changes when they get merried an start a family of their own, the love is always there its just matured and growed to include more.
7. Do you believe Siobhan can visualize the future she wants as Carlisle believes?
Any thing is possible at this point

....... No not on the outcome of the Volturi........ Yes on maybe smaller peaces of the future that doen't invole meny people an with less at stake.
