Are you ready to have your worlds rocked, Potterheads?
While it would be impossible to get into all the intricacies of the essay here, as the author goes through the entire Harry Potter saga, the gist of it is this: Hagrid is way more powerful than he seems, and the coincidences regarding his influence are a little too persistent to be mere coincidences.
For instance, Hagrid is the one who introduces Harry Potter to Professor Quirrell, Voldemort's secret host in the first book. Hagrid and Dumbledore are also the two people who Tom Riddle (a.k.a. Voldemort) really knew while he was a student at Hogwarts. This means Voldemort’s longest known relationships are with these two men. We know that Hagrid is close with Dumbledore throughout the series, but what about his relationship with He Who Must Not Be Named? They clearly have some history.
In addition, Hagrid avoids fighting against the Death Eaters before the Battle of Hogwarts in the final book until he is sure they are going to lose.
Plus, Hagrid’s magical abilities are categorized at an extremely high level, used only by Death Eaters or very powerful wizards and witches, such as his use of unaided flight in the first book, when he collects Harry from the island without a broom or his trusty bike.
Is this all pure coincidence, or is Hagrid really a follower of Voldemort's?
If you have some time (and totally want to ruin your perspective on the beloved character), make sure to read the Redditor's theory in its entirety. It will make you want to re-read every book through a new, slightly tainted lens.
