" As the Dark Lord becomes ever more powerful, your race is set still more firmly above mine! Gringotts falls under Wizarding rule, house-elves are slaughtered, and who amongst the wand-carriers protests?”
“We do!” said Hermione. She had sat up straight, her eyes bright. “We protest! And I’m hunted quite as much as any goblin or elf, Griphook! I’m a Mudblood!”
“Don’t call yourself —” Ron muttered.
“Why shouldn’t I?” said Hermione. “Mudblood, and proud of it! I’ve got no higher position under this new order than you have, Griphook! It was me they chose to torture, back at the Malfoys’! "
