"The Dark Lord called other Death Eaters. He was furious, of course they blamed me. He ordered the others to punish me the way I deserved to be punished. They nearly beat me to death that night. They didn't use their wands, I didn't deserve to be punished like a wizard, but "as a filthy squib’ he said. But all I could think about was that Hermione, Potter and Weasel made it and hopefully the war would end soon. My mother collected a sample of my blood while she was healing me. She mixed it with Hermione's blood and created the wards you saw earlier. Severus helped her create a potion to seal the room. Just after her death, the room became accessible again. Mother entered my mind while she was healing me, I wasn't able to stop her. She saw everything Hermione just showed me hours earlier. She recognised the Hufflepuff’s cup, and she got an idea of what Hermione, Potter and Weasel were searching for. She searched my memories of our fifth and sixth year. She tried to get to know as much about Hermione as possible. It took me some time to figure out, she just wanted to get to know Hermione the way I knew her. My mother was sure she wouldn't see the end of the war and wanted to have a chance to get to know her somehow. Two weeks later, Lestrange started to feel sick and became ill. The day my mother freed Daisy was the day Bellatrix died."
