1. What was your reaction when you realized that Alice had sketched Bella's house in Phoenix?
I thought, "Oh no." James was clearly not giving in whatsoever, and he was smarter than expected. I knew he would bring Renee into the picture, as that's how most predators wheel in their prey.
2. Why do you think Bella chooses not to tell Alice and Jasper what is going on.
A part of guilt, I believe. Bella is already worried that she's creating more harm to the Cullens than herself. By telling Alice and Jasper about the phone call, she feel she's putting them in more danger than they already are. It can also be that she's willing to cooperate with James (now that he's got Renee) and hope that her decisions will prove something good at the end.
3. Bella is able to resist Jasper's calming power. Do you think she actually successfully resisted, or that he gave up when she broke contact?
I don't think Jasper was trying as hard as he could, as he's fairly new to the diet and he knew any more temptations will make him go wild. This could be why Bella was able to resist it better than the others.
