"It's time," Bellatrix said to Voldemort once the other Death Eaters had left the room.
"What do you mean, it's time?" he asked absentmindedly, reviewing his plans that he had written down.
"I mean, it's time for me to go." She looked at him pointedly. "You know, so I can get rid of 'this thing'?" She gestured toward her belly. She had hidden the fact that she was pregnant from the other Death Eaters by wearing oversized robes and a corset to squish her belly in ever so slightly. But now the corset was squishing a bit too hard, the pressure causing her to have slight pains. Or maybe those were the contractions?
"Ah." Voldemort looked at her with sorrow in his eyes. "I hate to have to do this, but I have my reasons. Gather a few of your belongings and be on your way. My bed will await your return."
Bellatrix didn't normally react to the way her Master worded things, but this was one time she had to speak up. "You bed? Not you? But simply your bed? If I knew it was your bed that would miss me instead of you, I wouldn't be in this situation to begin with!" She ran out of the room to hers and hastily began gathering belongings.
Voldemort followed her. "Bella, I didn't mean it that way, you know I didn't."
"Sure. Tell that to your bed. I think it's getting jealous of all the attention you're giving me."
"Bellatrix, stop making these jokes and listen to me."
She turned around. "No, I don't think I will. Now if you'll excuse me, I have something to attend to." She reached up under her robes and tore the corset off. The pressure that was removed relieved her of her pains for only a short while, but that was enough for her to apparate. "Goodbye, then," she said, and then turned and disappeared.
Bidelia looked at the picture she snatched from James. It was true; she did have the woman's deep-set eyes. And her hair was the same texture and color. But the woman couldn't have been Bidelia's mother, it was too horrid. How could she have been the daughter of the top Death Eater? And who was her father?
"Why did you show me this?" she asked in a manner that was quite calm for someone that had just found out her mother was a Death Eater. "Why, if you knew it was this bad, did you let me know who my mother was? Why, James?" With every word, Bidelia got louder to the point of screaming.
James cowered before her. "Because I thought you might want to know."
"Why would I want to know that?" She began crying. "Why would I want to know that I came from such a horrible person?"
"You have to know."
"But why?" She wiped the tears from her face. "I know what I'll do." She stood up and grabbed her bag. "I'll go see the Headmistress. Maybe she can help me."
