Regulus hums, "His diary, which you saw Evan holding, Marvelo Gaunt’s ring--his grandfather’s ring, Helga Hufflepuff’s Cup, Rowena Ravenclaw’s Diadem, his snake Nagini, and Salazar Slytherin’s locket." And with that, Regulus reaches into his shirt and pulls out the locket that he had worn around them for years, "This is the first horcrux that I had learned the location of. I had Kreacher make a fake one and wore it around for years so no one would become suspicious when I traded it for the real one."
