--Narrator POV--
Edward and Bella were walking through the forest on their way back to Carlisle and Esme's, hand in hand, just enjoying the scenery and the time together. This was their daily routine, and it allowed Renesmee a chance to run around in circles and have some "play" time with Jacob, her Jacob. Just like Jacob had done when had pledged his love to her mother, Bella, he now pledged his love in a much stronger form to Nessie, through imprinting. There were a few issues that they had between each other since Jacob had imprinted on her, but not bad issues, just difficulties. For instance, Jacob was only a werewolf, it was better than being human, but he still wasn't meant to live forever, like little ol' immortal Nessie who could. Being half-vampire/half-human made her capable of reaching full growth at seven years of age and then left her frozen in time forever. She was half-vampire/half-human because she had been conceived inside of Bella, while Bella was still human. Thanks to a promise that Edward had made Bella that they would share a few more "human moments" together before he turned her into a vampire. And even though Bella had never initially intended or expected it to go as far as actually conceiving a child, she was happy that it did, because she loves Renesmee every bit as much as she loves Edward. It did continued to make Rosalie a little bit jealous, but she got over it as she and Bella became better friends, or sisters. Nessie had been just like a daughter to her, while Bella was burning from the searing pain of Edward's venom running through her veins, transforming her into the beautiful and glorious vampire that she is today.
Edward and Bella had attended Dartmouth in New Jersey once Renessmee was fully grown, around 7 years after she was born. Renessmee and Jacob had also attended high scool in New Jersey. They had moved up there with Edward and Bella. They were living up there long enough for Jake and Nessie to graduate high school and go through four years of college. They returned a month ago and have been taking everything very slowly just for the fun of it. They said that it was time for them to go into mock retirement and grow old together. Emmett thought that was funny and of course threw them a bunch of sarcastic and totally unnecessary compliments. But that's just Emmett.
Now everything is back to normal, the Cullens still live in Forks, but thye're waiting for the next generation to start before they show themselves in public again. Normally, by now they would have moved to a new city and started over but Ness wasn't about to leave Jacob, and Jacob wasn't about to leave his home neither. Bella nor Nessie wanted to leave Charlie. So they remain for the time being, in "hiding." Until the generation that had had any contact with them had passed away.
What about Charlie you might ask? And Rene? Well Charlie and Sue got married a while back and their both getting old now, as the Cullens stay young and beautiful. He visits regularly, almost everyday, and he and Sue are happy. Of course he still refuses to hear the whole story, be he knows enough. After watch Renesmee grow up to full maturity only 7 years after she was born and watching no one else change at all. We don't fear the Vultur anymore, not after our last little meeting so we don't worry about them finding out about Charlie, a human, knowing about the Cullens being all vampires. And Rene, who has not seen Bella since her transformation stay sidtent but talks with both Bella and Esme. Rene still doesn't, and probably never will know as muchn about the Cullens as Charlie does. But then he's stronger then Rene and convently closer to the Cullens, so it works out in the end.
