"Kreacher is a crucially, deeply underappreciated character in the Harry Potter series. Initially introduced as a bitter, muttering house elf loyal to the pure blooded supremacy of the Black family, Kreacher seems little more than a nuisance, echoing the hateful ideologies of his mistress, Sirius Black's mother. But as the story unfolds, we discover that beneath his resentment lies a deep, unwavering love for Regulus Black, the only master who ever treated him with kindness after whose death Kreacher was heartbroken, carrying that loss silently for years."
