After Goldy appeared, Harry told him, "Please go to Director Ragnok and tell him: Harry Potter, Lord Malfoy, has killed Tom Riddle and all his minions inside Malfoy Manor. Director Ragnok surely knows this, but he doesn’t know how I did it. Tell him that I’ll tell him how in person, not in a letter. Also tell him that we killed Riddle’s big snake, and I think we destroyed a horcrux in the process. If Director Ragnok has any questions that you can answer, do so; hold back nothing."
