Over the years, Harry Potter fans have found several secrets about the novels, one of which may have always been foreshadowing.
Since the films and books were first released, several behind-the-scenes revelations regarding Harry Potter have surfaced. J.K. Rowling, for example, is constantly revealing new information about her characters, such as notifying the public that fans were mispronouncing “Voldemort” and telling the truth about Dumbledore’s sexuality. Over the years, Harry Potter fans have cherished the series’ details, and it turns out that one particularly gruesome scene in the novels was hidden foreshadowing all along. The Fantastic Beasts films told that Nagini wasn’t indeed a snake, and the franchise continues to uncover secrets. Instead, the character had been a Maledictus all along.
Since the release of Harry Potter and the Sorcerer’s Stone in theatres more than two decades ago, the film franchise has been a worldwide hit. The films’ cast was recently reunited for a reunion special dubbed Harry Potter 20th Anniversary: Return to Hogwarts, which aired on HBO. During the special, the actors discussed behind-the-scenes secrets and how the show affected their lives. During the reunion, Rupert Grint, who plays Ron Weasley, remarks, “No one else can genuinely grasp what we suffered.”
Another mystery about the plot has now been revealed, and it displays a horrific event that has been foreshadowed all along. Harry uses Floo powder for the first time in Harry Potter and the Chamber of Secrets and ends up in Knockturn Alley. A woman meets the young magician with a plate of human fingernails. Hagrid quickly arrives at the rescue and removes her fingernails. In the novel, the scene is odd, and one theory (via Reddit) suggests it always had a deeper meaning. In addition to Floo powder, Chamber of Secrets introduces Polyjuice Potion, which allows a wizard to transform into a different person. So the lady in Knockturn Alley was probably selling fingernails so her customers could pass themselves off as someone else.
Harry Potter and Chamber of Secrets is the fantasy novel written by J.K. Rowling. The evidence for Polyjuice adds up. In her writings, J.K. Rowling used a lot of foreshadowing. For example, several times before the author revealed it; the novels intimated that a piece of Voldemort’s soul was inside Harry. With Polyjuice Potion requiring a part of the person you’re transforming into, the fingernails weren’t just there to make the scenario strange. Furthermore, when Hermione, Ron, and Harry first discover the Polyjuice components, Ron is concerned that he would have to drink “Crabbe’s toenails.”
If the foreshadowing in the novel was foreshadowing, it was buried well enough in the film that it was not included. A fingernail-wielding vagabond does not confront Harry Potter in Knockturn Alley in the film adaptation of Harry Potter and the Chamber of Secrets. Instead, in the Harry Potter film, a large band of nefarious individuals surrounds the Boy Who Lived. In the end, Hagrid saves the day, but the group is dissatisfied. If they’d had more time with Harry Potter, they might have been able to persuade him to buy something from their stock of fingernails.
