Well, thank you Prometheus for starting the "not a prequel, honest, I swear" prequels craze.That said, I adore IAL book and always thought it would be interesting to see what has become of new species society they tried to build at the end of the book. Howeevr, since the movie didn`t keep that part of the book, I really don`t know. In the book, they could easily bring back Neville because we had to believe that he was poisoned so that he wouldn`t suffer a slow death by the raging crowd. But he could have been only knocked out or something. The woman realized that her new society wasn`t perfect so she could have saved him for later if going gets tough and his help was needed. There are many ways one could undo the "death". But perishing in an explosion? Tough call. last time they un-did it, it was end of WotW that everyone`s harping on still.
