MISTAKES
In book two Lockhart says thet Proffesor Snape would make anyone a love potion, But love potions are NOT allowed.
Why does Harry need a ticket for the Hogwasts Express in the first book, But not in any of the other books.
The School List for the 1st years says you can bring a Cat, Toad or Owl.....But Ron brings a Rat! Whats up with that?
First Book pg 122....it says there are only three people left to be sorted but there are really four.
First Book pg 283....Ron takes a step forward,but he's posing as a knight and knights can't move forward.
Third Book pg 285.....Second to last line says Snap instead of Snape.
Book Four...Dudley threw his playstation out the window,but playstations were not released in 1994
Book Four pg 428.....It says Dumblefore instead of Dumbledore.
Book Four...When harry is in the perfect bathroom, Myrtle gets upset when he said "breathing". But then she sniffed loudly, and sniffing is a form of breathing
Book Four pg 169...On the 8th line it says "A gleeful smile speads across malfoy's pale face" and the is not a period.
Book Four...Eloise Midgeon is spelled Elise Midgen by the end of the book.
In book to it says Perry instead of Percy (Sorry forgot what page. Near beginning)
When Hagrid comes and gets Harry out of the little hut on the rock, they use the boat that the Dursleys used to get to the rock. So how do the Dursleys get off the rock?
At Nearly Headless Nick's Deathday Party, it said Peeves pelted Moaning Myrtle with peanuts, but he couldn't have, they would've just flown right through her, right?
Just a thought but... security for the Sorceror's Stone could have been much better. If three first-years can get to the stone than you can bet any fully-trained wizard can do it. They could have just had a password that nobody but Dumbledore knew. Then he could tell Flamel if he had to use it than change the password right away.
In chapter 7, page 122, it says that Harry looked up at the Sorting Stool, there were only 3 people left to be sorted, Professor McGonagall calls the names of 4 more people instead.
"In Book one (it said), Prof. McGonagall brings out a 4 legged chair with the sorting hat (to the sorting ceremony). In book four (it said) she brings out a 3 legged chair with the sorting hat. What happened to one of the legs?"
In book 1, it is almost Nearly Headless Nick's 400th death day (years since he died). But in book 2, he celebrates his 500th deathday.
In Book 1, JK Rowling wrote that Ron was the knight in the giant chess set. However, it later said that he had to 'move ahead one' so the Queen could take him, opening the path for Harry and Hermione to checkmate the king. If he was a knight, he could only move 1) ahead one, sideways two, or 2) ahead two, sideways one, like an "When Tom Riddle was talking to Harry in the Chamber of Secrets he said that they were similar because they were both half bloods. But Harry isn't a half blood. Lily and James were both wizards and witches. (Many people say that because Lily was muggle born that makes Harry a half blood, but that is not true. If both parents are witches and wizards you are not a half blood. Half blood means ONE parent is a witch/wizard and the other is a muggle.)
When Harry goes back in Riddle's memory, Hagrid was expelled when Dumbledore wasn't headmaster -Professor Dippet was- but Hagrid said Dumbledore let him stay as gamekeeper at Hogwarts. (Perhaps Dumbledore let him stay on, even though he wasn't the headmaster, he was just a teacher)
The basilisk kills people by looking at it straight in the eye. But Myrtle and Harry both wear glasses. Colin was petrified by looking at it through the glass lense in his camera, so wouldn't Myrtle just be petrified too? The only other explanation is that maybe Myrtle had taken her glasses off to cry while she was in her stall.
In Chapter 19, The Servant of Lord Voldemort, page 370, it states that Voldemort had been hiding for 15 years. If his power was lost only twelve years ago, why was he hiding that extra three years?
Remus Lupin recalls in his fifth year that OLD Madam Pomfrey used to walk him down to the Whomping Willow for him to transform. When Remus becomes a teacher almost 15 years later, Madam Pomfrey is still the nurse. Exactly HOW OLD is Madam Pomfrey?!?
In chapter 3, The Knight Bus, the driver Stan told Harry that the price to get to London was 11 sickles (an' fer firteen you get an...). But in the book it said Harry gave him gold which are galleons.
In Book 4, it states that it is the 422nd Annual Quidditch World Cup. In Quidditch Through The Ages, it states that the first World Cup took place in 1473. "Assuming my calculations are correct(Dumbledore)", that would mean the World Cup talked about in Book 4 takes place in 1895!
After Hermione dropped Muggle Studies, she said she had the same amount of subjects as Ron and Harry. But she still had (besides the mandatory ones) Arithmancy, Care of Magical Creatures, and Ancient Runes. Which is more then Harry and Ron who each had only Divination and Care of Magical Creatures.
When Harry recieved his letters from Hogwarts in Book one, it said they poured out of the fireplace. But in Book four the Weasleys were unable to get through the boarded up fireplace to pick up Harry as it was an electric fireplace. (Possible explanation: the fireplace was boarded up only after the letters started shooting down the chimney. Maybe Vernon Durlsey boarded it up so if it happened again, Harry couldn't get one.)
In Book four Fudge, Dumbledore, and Moody are talking ABOUT Crouch. But instead of Fudge yelling to Dumbledore, it says: "said Crouch angrily". He wasn't in the room... they were talking about him not with him.
Portkeys are supposed to transport whoever is touching the portkey at a prearranged time. But, Harry and Cedric were transported to Voldemort and the Death Eaters the SECOND they touched the Triwizard cup. Don't you think that sounds a little bit too... coincidental? Also, couldn't Moody/Crouch have just made Harry's pillow or something a portkey and transported him when he went to sleep at night? Wouldn't that have saved all the effort of guiding him through the whole Triwizrd tournament?
