How we cite our quotes:
"I need you to become the place you became for Draco Malfoy…" (21.102)

"It is Voldemort's fault that you were able to see into his thoughts, his ambitions, that you even understood the snakelike language in which he gives orders, and yet, Harry, despite your privileged insight into Voldemort's world (which, incidentally, is a gift any Death Eater would kill to have), you have never been seduced by the Dark Arts, never, even for a second, shown the slightest desire to become one of Voldemort's followers!" (23.152)
