1. Were you surprised that Jacob actually phased in front of Charlie?
I thought it was damn stupid of him to do it, but not that surprising when you think about Jake's impulsive, thoughtless nature.
2. Given the self-control Bella has shown since becoming a vampire, were you surprised by her physical reaction to Charlie?
No, it was natural. What wasn't natural was that she kept to her seat.
3. Bella does a lot of worrying in this chapter. Are her concerns founded? Is worrying a productive emotion?
I think it's understandable, as her concerns are very serious ones, but worrying isn't all that productive, no.
4. Has Jacob, in fact, done the Cullens a favor or has he put Charlie and the rest of Forks in danger from Bella if the Cullens don’t leave?
Jacob did something incredibly risky. It is ironic that he criticised Edward for allowing Bella to think that she could be near Charlie "Charlie seems like a strange choice for her first meal" but as soon as it's to his benefit, he's all for it. Yes, she clearly has more control than other newborns, but it was still very risky, and it only worked because Bella was strong, not because he did the right thing.
5. Charlie wants to be included in Bella’s life, but clearly doesn’t want too many details. Do you think Charlie will eventually want more information? If someone close to you was keeping a secret, for your own good, would you be content not to know or would you ask questions until it was all out in the open?
I think that Charlie will take what he can get and be happy with that. Now, Renee is another question, and one that will need to be dealt with down the track. She's not going to be satisfied with no visits and no information.
