Theory

First off these are the next three quotes

9.Alice: "No one will dare to call you plain when I'm through with you."
Bella: "Only because they're afraid you'll suck their blood."

10.Edward: "Oops."

11.Renee: "Alice wouldn't let us do anything else. Every time we tried, she all but ripped our throats out."

My mom and I have more theories about the quotes and Breaking Dawn. First we think that Charlie has to know that the Cullen's are vampires, unless Edward becomes human again. And we now have a new guess at how he can become human. We think the Quillette Indians know because have all those legends so all they have to do is remember them and tell the vampires. Then Jacob will be happy and can be her friend again (Sorry Victoria but I like Jacob).
