Silly question. Can’t get it out of my mind, though. I’m sure there is a simple answer, probably explained in the book, but I’ve only seen the movie.
“Harry Potter and the Deathly Hallows, Part I.”
–In a scene at the abandoned and hidden Black home, in London, Harry seizes the Black family’s house elf, Kreacher, and questions him about the late Regulus Black’s locket, now missing. It turns out the locket has been stolen by Mundungus Fletcher (great name, J.K.). Harry sends Kreacher to fetch Mundungus, a task soon accomplished.
–Earlier Potter movies say house elves are the exclusive property of the family they serve. Kreacher confirms this in Prisoner of Azkaban by saying, when angrily admonished by Sirius Black for his pureblood ranting, “Of course master, Kreacher lives to serve the House of Black.”
My question:
With most of the Black family now dead, and the house apparently abandoned, how is it that Harry Potter has the authority to force Kreacher to answer his questions and obey his will?
Harry is not related to the Black family, but was only the godson of Sirius Black, now dead. In addition, Bellatrix Lastrange and her sister, Narcissa, are stated to be cousins of Sirius Black (by Sirius himself, interpreting a family tree painted on a wall), and are thus related to the Black family while being the bitter enemies of Harry Potter.
So, why does Kreacher feel compelled to answer Harry’s demands, even when out of “wand range” on a mission to capture Mundungus?
