Question: This question pertains to New Moon and Eclipse: When Billy is telling the story of the Quileutes and the "cold ones", he says the cold ones can only be destroyed completely by fire. We've seen James and Victoria be destroyed that way, but Laurent and Riley were killed by the wolves. Was fire not necessary in their deaths (there was no evidence that the female vampire in the story was further destroyed by fire) or is it really not the only way vampires can be destroyed completely (according to Stephaine Meyer at least)? It seems unlikely Jacob and the rest of the pack would have matches or lighters with their clothes every time they remembered not to phase with them on.

Question: In the scene where the Cullens are filling Jacob and his friends in about the newborn vampire army, this is all taking place during Bella's graduation party. Why would they discuss it there where other people could hear them or notice them? In the book they discussed it later that night after the party.
