Harry Potter and the Deathly Hallows
The Home Quotes
How we cite our quotes:
Tom Riddle, who confided in no one and operated alone, might have been arrogant enough to assume that he, and only he, had penetrated the deepest mysteries of Hogwarts Castle. Of course, Dumbledore and Flitwick, those model pupils, had never set foot in that particular place, but he, Harry, had strayed off the beaten track in his time at school – here at last was a secret he and Voldemort knew, that Dumbledore had never discovered –. (31.87)
Again, Harry proves his odd kinship with Voldemort – both of them know the Castle's secrets better, perhaps, than anyone else, since it's home to the two of them. It's taken all of Harry's transgressions as well as his good deeds to get this close to Voldemort, and to figure out the Dark Lord's secrets.
He wanted to be stopped, to be dragged back, to be sent home…
But he was home. He and Voldemort and Snape, the abandoned boys, had all found home here. (34.31-32)
Hogwarts is home to Harry, and there's no other place for him to go. Abandoned and orphaned once, he has come back to the only place he truly knows. And, poetically, he returns to face another orphan whose only real home was this school.
