J.K. Rowling gifted all millennials the most popular magical world, but even she does not consider her books flawless. There are several moments in 'Harry Potter' that the creator would gladly correct if she had a Time-Turner. And believe me, fans would wholeheartedly support these changes.
The Marauder's Map
Magical artifacts that grant their owners immense powers often contradict certain plot lines. The Marauder's Map is one such example. This local "omnipotent" artifact, created by four schoolboys, allows its owner to see absolutely everyone who is within the walls and surroundings of Hogwarts, even if they are disguised.
Harry, who received the map, did not always realize its true value and power, and Rowling herself admitted that she regrets giving it to Harry. She believes the map should have remained hidden in the office of the fake Moody, who should have kept it out of harm's way. However, the author also emphasizes that in the scene of the 'Battle of Hogwarts,' the map revealed its full glory. Let’s remember: at that time, Harry used it to keep an eye on Ginny.
Ron and Hermione's Romance
The romantic storyline between Ron and Hermione sparks debates among fans. Many believe that Hermione should have chosen Harry instead of Ron, no matter how kind and good he was. Rowling herself admitted that she conceived Ron based on her best friend and wrote Hermione as a reflection of herself. Years later, the author confessed that the union of Ron and Hermione might have been a mistake, suggesting that their relationship would have been unstable in everyday life and that their marriage would have ended quickly.
Florian Fortescue
Florian Fortescue, the owner of the ice cream shop in The Chamber of Secrets, was originally intended to be a key character in The Deathly Hallows. In Rowling's early plans, Florian helped Harry, Ron, and Hermione search for Horcruxes and served as a replacement for the wise mentor figure of Dumbledore. However, with the introduction of new characters—Phineas Nigellus Black and the Grey Lady—Fortescue's role became unnecessary, and the author decided to kill him off. Despite this, Rowling regrets his disappearance and feels guilty about what she did to him.
Aunt Marge's Vicious Bulldogs
In Prisoner of Azkaban, Marge is portrayed as a quarrelsome lady with aggressive English bulldogs. However, Rowling learned after the book's release that aggression in the breed has been genetically eradicated for several centuries. Bulldogs are inherently kind and can only attack a person if they have a severely damaged psyche. Despite her nasty demeanor, Marge adored her pets, so the most they could do was slobber on Harry's cloak.
