What would happen if Edward never came back during New Moon? What if Laurent turned Bella into a vampire that day in the meadow, because Jacob and the other wolves didn't get there in time? What if there was nothing Jacob could do to save her? What if Bella's shield gets so strong when she turns her into a vampire, that no other power can affect Bella, meaning Alice can't "see" her. What if Bella gets her own coven? What if almost 60 years later Bella and her coven move back to Forks? What if the Cullen's are there too?
