Something is still screwy with the Fidelius Charm. Earlier they mention they had to abandon Grimmaud Place as the Order's Headquarters because the Charm was so weakened. Anyone who had been told of the whereabouts became a Secret-Keeper, and it could be tortured out of any of them. But Snape already knew! Why couldn't he tell other people where it was? They only ever worry about Snape breaking in, not Snape telling others how to break in.

Furthermore, back in the fifth book we saw Dumbledore in Grimmaud Place. If the Secret-Keeper can enter the protected dwelling, why weren't James and Lily Potter their own Secret-Keeper? They could have kept their location a secret, and then waited for everything to blow over.

Another thing: Harry and the gang are so careful to Apparate to the top step at Grimmaud Place, under the Invisibility Cloak. But it's hard to keep balance and pull-off well. Why not just Apparate to the bottom of the steps, the road, or ever a block away, and walk in under the Cloak. Less chance of letting the Cloak slip. And I thought in the fifth book we saw Order members Apparate from inside the house. Didn't Fred and George Apparate every few feet, Apparate into Harry and Ron's room? All of the sudden Harry, Ron and Hermione can't just Apparate into the house?

And we see Kreacher Apparate out of the house. Even if it's just a difference between house elf magic and wizard magic (we've seen house elves Apparate at Hogwarts, which seems like a great way to smuggle people in), they could hitch rides with him.



I wonder if the Ministry had Taboos set up on the Unforgivable Curses. It'd help them track anyone saying the words "Avada Kedavra" or "Crucio" or "Imperio".



Neville might mention it later, but Hermione is where we first hear about it, during the camping trip. She says you can alter food, even duplicate it, but you can't create it out of thin air.
