Past Accusation Revealed

The Memory of Fifty Years Ago
Entering the Diary
Harry discovers Tom Riddle's diary and is drawn into a memory of fifty years ago. He sees a young Tom Riddle accusing Hagrid of opening the Chamber and setting a monster loose. The monster is Aragog, a giant spider, but it was not the one that killed the girl.
Hagrid's Expulsion
In the memory, Hagrid is expelled for keeping Aragog. Riddle receives a special award for services to the school. Harry initially believes Hagrid was guilty, but later learns the truth.
The Truth Uncovered
Aragog himself confirms that he never harmed anyone and that the real monster was something else—a basilisk. Hagrid was merely a scapegoat, and Riddle manipulated the situation.

The Ominous Warning
Before leaving, Hagrid tells Harry and Ron to "follow the spiders" if they want to find the truth. This clue becomes crucial. Dumbledore is also suspended, leaving the school vulnerable.
