At that same moment, the Heir Malfoy ring disappeared off Draco’s finger. Draco, after speaking with his mother, will know that his father is dead. But they won’t know, till we tell them, why Draco no longer has his Heir Malfoy ring and why Narcissa’s Malfoy marriage ring was not replaced with a Regent Malfoy ring. It wouldn’t surprise me to find a letter from Narcissa waiting for me in my office, demanding to know, "What’s just happened?’ "
