Except the first book all other books have some "
major" errors. These just irritate me because JKR usually plans many things right from the beginning like the bezoar thing.
Please tell if such inconsistency mistakes that you have found. These mistake just do not make any sense and just are glaring loopholes.
7. Snape was the Hogwarts headmaster when he died. Then I think his portrait should also
appear in the headmasters room. Also where was DD when Harry came into the Headmaster's room to see Snape's memories. Watching the battle from other portraits?
Why doesn't Harry destroy the elder wand?
6. Malfoy using a curse against Harry when he is inside the cloak.
5. Tonks using magic when they come to take away Harry. Just very wrong.
How did the Death Eaters get their wands back?
4.
a.) The reason for Harry to win the Triwizard Tournament is not clearly explained. If Barty Crouch didn't send Harry right away to Voldemort because his sudden diaspperance would raise suspicions, this is not a solid reason. Because by then Voldemort would have risen again and Barty Crouch could have just disapparated outside Hogwarts.
Maybe JKR should have told us that magical process by which Voldemort rises again should be done for one whole year etc., so Harry should be sent to him by the end of the year.
Also it doesn't explain how nobody would not notice if Harry disappeared in the maze and the tournament cup is missing. JKR should have put something like Barty Crouch had a fake
cup which he would place at the place of the original cup and everyone would think that Harry was torn to pieces by some creature in the maze(so also decoy clothes, eye glasses etc).
b.) How can James come out before Lily during Priori Incantatem. I think JKR just did that to
because it would be nice if Harry's mother came out last.
Also how did Voldemort's wand return to him? Maybe it was just at Godric's Hollow and then Wormtail got it.
3. The time turners. JKR should have put a small explanation like they can take you back in time only from the time you wear them or activate them, so you cannot go back anywhere in time.
2. The charm that Lockhart claimed that he used to convert a werewolf to a human. If it was such common knowledge then why DD or Snape etc., didn't notice this. Don't tell me DD was so careless. JKR should just made Lockhart say that he killed the werewolf.
