Thinking it through, Ron counted up his fingers, "First, he sent Hagrid to Gringotts when he had Harry in tow. That was practically an invitation to snoop around. The same year he explained to him how the Mirror of Erised worked, the final hiding-place of the stone. And honestly, how could the headmaster not know that something was wrong with Quirrell? He worked with the man for years! Second-year, the Chamber! He told us that "aid would come to those who are loyal', and during the fight, his own familiar brought Harry the Sorting Hat with the Sword and saved him from the basilisk venom. Bill, phoenix tears are the only substance powerful enough to counteract basilisk venom. Hermione looked it up. And what kind of wards does Hogwarts have if they don't even warn the Headmaster of an object as dark as Riddle's diary? The Dementors? I mean, come on, you saw Pettigrew last week. Sirius Black was sent to Azkaban without a trial. Without even being guilty? Dumbledore is Chief Warlock and Supreme Mugwump! Don't tell me that he could not have done anything. At least he could have asked a few questions, even without getting directly involved! And this year? You're a curse breaker, tell me, was there a way to get Harry out of the contract with the cup?"
