2. How did Snow and David know what the dagger does? I wondered that one as well, one moment earlier on in the series no one seemed to know about the dagger/what it did and the next absolutely everyone seems to know about it. I don't think it is in the book otherwise Gold would not have been so surprised with August and would not have needed to ask how he knew about it. I can only guess that the Blue fairy or August spilled the beans on it to everyone....
