it is all part of the 'new life' theme from the end of film deleted scene, which really should be rendered and finished, a great scene showing Jake being tender to a pregnant Neytiri, as they are fishing in the river, kids playing around them, pregnant Na'vi women everywhere. the scene was designed to show that the planet, the Forest, and the People will heal and thrive, and go on. i, for one, am happy to see the next generation of kids who will one day be hunters and warriors. long live the Omaticayans!
it is absolutely great to see Avatar production underway at last!!!
