1. Where did you think Edward had gone off to at the start of the chapter and why did you think he had vanished?
I already knew that Edward was a Vampire, and from that I concluded it had to do something with that, with a hint that Bella was there.
2. We learn a few things about Bella's parents in this chapter. Charlie can't cook - Renee is rather needy and so on. What does this tell us about Bella as an individual?
I think it's just a personal thing she grew up with. From the sounds of it, Bella has visited both parents while she was younger. So maybe it was just something she learned while trying to fit in with her mom/dad. To take care of what they can't do, while they do their parenting part. If Charlie could cook, then Bella wouldn't really need to worry about cooking. If her mom was not forgetful, Bella wouldn't have to "take care" of her, or what ever.
I just see it as she is a adaptive child, and learned skills that would help her parents out.
3. What was your reaction to the polite way Edward treated Bella when he returned? Did you think he was putting on a show? How did it change your thoughts about his initial reaction to her?
I thought maybe it had to do with Edward feeling sort of guilty, or that it was Bella being over reactive to some scrutiny he had.
4. What was your first explanation for the change in Edward's eye color?
He's a vampire?

I thought it was since his mood changed or something.
