I don't know why, but the paragraph below fascinates me
"But surely if the boy had destroyed any of his Horcruxes, he, Lord Voldemort, would have known, would have felt it? He, the greatest wizard of them all, he, the most powerful, he, the killer of Dumbledore and of how many other worthless, nameless men: how could Lord Voldemort not have known, if he, himself, most important and precious, had been attacked, mutilated?"
This is such a cleverly-crafted paragraph. It perfectly balances two extreme opposite propositions: Voldemort's ultra-inflated ego and immortality, and at the same time the harsh underlying reality of his vulnerability and mortality.
