1. Given everything we learn from Edward about the fact that he was able to stop from drinking Bella's blood, but that he didn't like how she smelled when she had a transfusion, what does that say about his control over the way he thirsts for her blood? Do you think drinking her blood makes it easier or harder for him to resist now?
He isn't an animal anymore -- he is in control enough to notice those subtle differences because of all the years he has spent abstaining from human blood. Another vampire -- even Jasper -- would look at it as "blood is blood," but Edward is more nuanced. The fact that he knows how good it tastes could make it worse. He knows the exact taste, he knows what he's missing. However, I think that seeing her nearly dead has had it's impact too.
2. Edward admits that Alice has seen Bella as a vampire. Why do you suppose, since he of all people knows it's crazy to deny Alice's visions, that he is so resistant to giving in and changing Bella?
Because he wants her to remain human and he thinks that there is a possibility that his will -- and the choices he makes -- might be strong enough to end up proving Alice's vision wrong.
3. Bella begs Edward to never leave her. Although he never exactly promises NOT to leave her, he does say it would be impossible for him to even try. Knowing what we know about New Moon, do you think he was saying this as a way to tide Bella over and keep her calm for now? DO you think he had plans even at this point in the story to one day leave her?
I don't think he plans to leave her. He might think that she would be better off if he could leave her, but he is so in love that he cannot stand even the thought of leaving -- though he would, if she were willing, as is shown by his reaction to Florida. However, later, when he sees Bella's life at risk again -- this time by a member of his own family -- he is able to find the strength to leave, even though it isn't what he (or Bella) wants.
4. Bella and Edward argue about her becoming a vampire, to which he point blank says that he will never do that to her. When I first finished reading Twilight, I was very torn over whether or not Bella should become a vampire. How did you feel at this point? Try to ignore all the discussions you've had here at the lex and focus on your first initial reaction. Did you think Bella should be changed right away and leave her family and life behind, or did you think Edward was being sensable to tell her that her mortality was important and more natural than anything he could give her?
I wasn't torn at all. I thought he was being silly. I thought perhaps it would make sense for him to ask her to wait a bit, because their relationship was so fresh, but in my mind, if they stayed together then she would need to be changed eventually -- it only makes sense for them to be of the same "species" of sorts. Yes, it would mean leaving her family behind, but then again, if she stayed with him forever she would need to do that anyway in order to hide the fact that her husband didn't age. Being with Edward, by definition, meant that a normal life was out of her reach, at least to some degree.
