List the mistakes, spoilers!

The one that sticks out in my mind the most was this, I think it was in the Fallen Warrior chapter. Something like...

Hagrid, Hermione and Lupin stood shoulder to shoulder....

I don't know if this is a mistake or not, Im probably just confused is all but...

They kept referring to a 'trace' still being on Harry even after he was 18. But in the previous books, didnt it say they could not detect who was doing the magic, just that some one in that household or area was? So where did this magic tracing come from?

yeah i know! that drove me nuts the whole book! cause tom riddle eluded the trace...why can't harry? and even more why did nothing happen in ootp when people used magic on him?

something inconsistant between Ootp and DH. Remember how in Order of the Pheonix Fred and George kept apparating inside the house? can they do that? if they can can they apparate out of it? cause why would Harry/ron/hermione/lupin have to be on the front step? but usually people have to go pretty far away from the house to apparate when it's protected don't they?

I thought that they figured out that the "trace" wasn't on Harry - it was that he was saying Voldemort, which was "taboo". And I think they said very specifically that they can only tell if someone has done magic around someone with the trace. So someone growing up as a Wizard, it's up to the family to control them (since Wizard parents could use magic). But in Harry's case, since there was no one magical around him, they could always assume it was him.

You can apparate in a house, but not Grimmauld Place because of the protections on it. I'm not sure why they could apparate on the front step - though I suppose the protection could have ended right at the door by design - the same way the protections at Hogwarts ended at the front gate.

The Harry, Hermione and Hagrid standing shoulder to shoulder I'm fine with. It's an expression.

fred and george were apparating inside of grimmauld place.

the trace was on harry at the begining and they thought that harry's traveling could be traced by the trace but they were unable to do so for riddle so it doesn't match.

Oh I forgot about that. Did they change it because they wanted to keep Snape out??

I was under the impression, as far as Grimauld Place, that you could, if the Secret Keeper told you the location, apparate inside the place if you were already inside it. If you wanted to leave it, you'd have to go to the door, and then do it. That's why all of the Order Members rang the door bell, which set off the damn painting, and pissed everyone off.

GwP, the trace on underage wizards basically tells the Ministry that there is an underage wizard there. If they detect magic, and know it's only him or her, then it has to be him. If there are over-age, or legal wizards about, they wouldn't know and still assume it was the underage wizard, because the legal ones don't have the trace. The trace, in essence, acts as a tracking device. If Harry left, the Ministry would know. They would not know, however Dobby was in the house in CoS, and therefor assume it must have been Harry's hover charm. The reason why Hermione and Ron, even though they were legal, were afraid to do magic around Harry, is that they were afraid he still had the trace. They'd know an underage wizard was there (but probably wouldn't be able to tell which one). Once Hermione or Ron did any kind of magic, they'd assume it was the underage wizard, since Hermione and Ron were legal and didn't have the trace on them. Therfor, since The Death Eaters prety much took over The Ministry of Magic, if an underage wizard did magic and was caught on the trace, a Death Eater would go and check it out and see if it was Harry. Does that sort it all out for you lol?

Grimmauld place is the House of Black, and yet, Kreacher keeps referring to it as the house of his Mistress's forefathers. Would Black have been her maiden name too?

Exactly. So why when they said to Lupin, could it be they never lifted the 'trace' of harry when trying to figure out how the death eaters found him, he said 'possibly' I guess its just another mistake!

Was I the only one who was convinced that Aurthur Weasley was under the imperious curse and had done magic to somehow replace the trace onto Harry's being? Of course I didn't believe that for the whole book, but I thought he was under the imperious curse from the time he returned to the Burrow from the Dursleys and for a couple of chapters afterward. lol.

Niether the Trace or the Taboo actually say who did the forbidden stuff just where it was done. So if an a trace just notifys that an underaged wizard did magic here or there, and Taboo is the same just instead with Voldemorts name.

Harry was bitten by the Basilisk in COS. Why didn't the Horcrux within him die then?

Well in DH in Snape's memory Dumbledore told Snape Voldemort was the one who had to kill Harry, I'm not sure why this is true but it was mentioned that it was Voldemort that had to destroy the horcrux within Harry, so I guess thats why the Basilisk bite in CoS didn't destory the piece of Voldemort's soul in Harry.

Or perhaps it was because Harry didn't die. Fawkes saved him before the basilisk venom could spread too much.

I believe that in DH, the avada kedavera, full out, supposed to cause instant death, hit Harry, though the bit of Voldemort's soul acted as a sort of cushion or barrier. It didn't kill him in COS because Harry didn't experience 'death' as he did in DH.

In GOF, Dumbledore hints towards international cooperation as being more important than ever now, that it may come in handy in the end. However, it all seems to be Britain, and Britain alone. Not even Madam Maxime is seen or heard from in this edition, that I recall...
