Draco knew the older version of his aunt was here. Maybe he could nose around with her and try to find out what was in the bank. What if it was a Horcrux? If Voldemort would have trusted anyone to guard a piece of his soul, it would have been Bellatrix Lestrange.
"Well, before the battle," Draco began, "there was an hour of waiting. The Dark L-... I mean, Voldemort, said that Potter was to turn himself over in the Forest, or he would kill all of us, especially anyone trying to help hide him. So, naturally, he went right to Voldemort. Voldemort hit him with the Killing Curse, and he fell. My mother was there to witness it. She was supposed to check that he was really dead. He was faking. Don't ask me how he didn't die. But my mother said he was dead because he told her I was safe in the castle. The Death Eaters carried Potter's body, still thinking him dead, back to Hogwarts to make a big show out of him. But he revealed himself when he cast a Shield Charm to protect the Weasley woman from a curse." Draco paused for a little breath, then asked, "Do you know anything about the Deathly Hallows?" He wasn't sure how familiar she would have been with the story, growing up in a Muggle family. For once, he did not think about this with much distaste.
Draco was rather surprised at her apology. "Thank you," he said, unsure of what else he should say. "I... she was a good aunt, but she was a little insane." To say the least.
