You know, last night as I went to bed, I realized it's a GOOD thing that the movie didn't happen in BTF-verse...
Nanoha would have gone berserk just after Fate got drained and there would have been black and gold energy and lightning flying around and the Wolkenritter would have had to have seen Nanoha's hand turn into shadow-claws that tore them and the Book to pieces...
Though the Protection Program, the weird device and Reinforce would have all been torn from the book before L-Sama took over.
