Tom Riddle, New Member of the Order of the Phoenix

Narcissa: "I still don't understand why the Dark Lord turned into a child and went to Hogwarts?" Bella: "The Dark Lord must have deep intentions in his actions. If I were to make a bold guess... I think Hogwarts will soon fall into our hands. The strongest fortresses are often breached from within!" Narcissa: "I see." Greyback: "So our mission this month... What are the Dark Lord's instructions?" Bella: "Free the house elves!" Lucius: "Ah? Why is this???" Bella: "To create panic, of course! Can you handle life without house elves?" Everyone: "It has to be Bellatrix, you are the only one who can guess the Dark Lord's thoughts."
