Hello, my name is Grace, and in about ten years or so you'll be buying my premortem biographies where they'll be flying off the shelves like Harry Potter on a Summoning Charm spree. Just kidding.
I finally managed to find the quote from Harry Potter and the Half-Blood Prince which was half burnt into my mind (p479): But he understood at last... it was the difference between being dragged into the arena to face a battle to the death and walking into the arena with your head held high. Some people, perhaps, would say that there was little to choose between the two ways, but [Harry knew] with a rush of fierce pride... that there was all the difference in the world.
