My favourite scene would have to be when Nicolas, Sophie, Josh and Scatty are with Dora.
Or when Scatty has Josh on the ground and she's like
'You're lucky. A couple of centuries ago I would have killed you. I used to have a bit of a temper, but I've been working on my self-control,'
Or, last but not least, when Hekate is a little girl. I can just imagine how stupid Flamel would have felt, begging a girl who looked 11 to awaken the twins' powers. I'm looking forward to seeing that in the movie.
