It was obvious he'd approach her first, she was a pure-blood and one of the most loyal of his followers. She also had a calmer air to her than most of the Death Eaters, she would be a good mother. He was obsessed with becoming immortal, he'd already created four Horcruxes, but he needed to create something else: a legacy. It was imperative to him to pass his genes on, and she would be able, and willing. He ensured she got married first, to reduce the number of questions asked. She and Rodolphus never actually loved each other though, she knew her purpose and kept herself chaste for Voldemort. Eventually the time came, his decision, he always had these things planned out. He disrobed and she was amazed at how thin he actually was, he always hid it so well. The sex wasn't very fulfilling, he seemed to be lacking in energy. But the deed was done. A few weeks later she took a pregnancy test. It seemed to deliberate for longer than it typically should, but it eventually became clear. It was positive, they had succeeded.

The pregnancy lasted about seven weeks. It was a weak foetus from the beginning, and as the blood vessels began to form it just lost all of its strength and died. Bellatrix was convinced it was her fault, she begged for Voldemort's forgiveness, but he seemed more distant than usual. He didn't respond to her, but she thought she saw him trembling too.

A few days later they heard about the murder to Hepzibah Smith. The next time he summoned them to bestow his commands, he looked even paler than usual, his skin more stretched out and his hair thinner. He asked Bellatrix to stay behind at the end. He wanted to try again.

This time the pregnancy lasted fourteen weeks. They knew the sex of the baby this time, it was a little girl. He'd picked Bellatrix based partly on her composure, she could make a good mother, but she seemed to be becoming more frantic, her voice more strangled and forced.

He was then gone again, something about Ravenclaw and an artefact. He lost the last of his hair after that.

For some reason, he wanted to do it with her again. She couldn't see why, she'd failed him twice before. But he was insistent, he said it needed to be her. She thought there must be other candidates, others who were pure of blood. She could feel their judging eyes upon her as she continued to fail him.

They did try again. His body was even more frail now, his energy lacking completely. The pregnancy only lasted six weeks this time. Bellatrix shrieked at Rodolphus, she blasted the house elf half way across the room and stabbed at the paintings. People around her were starting to become terrified for her, she was prone to fits of screaming if you bothered her nowadays. Even some of the Death Eaters seemed scared of her.

She and Voldemort tried one more time. This time, it was a success. It got to twenty weeks, and the foetus seemed to be healthy. There was no sign of it stopping.

The baby was finally born, a mostly healthy boy. She seemed to feel better about this her unkempt hair became slightly smoother over the next two weeks and she had almost abandoned her knives.

But then he came to tell her the news, he took her aside into a small room, and as he dragged his long finger through a slash in one of the paintings, he told her that the baby must be put in other hands. He wanted it to be raised far away from here, he'd chosen Albania. He said it was to keep it away from the more fervent Aurors of England who were looking for him. He kicked over the body of the mutilated house elf as she screamed and protested, but he was firm, and cold. He assured her it was all part of his plan for the future, for the new world he was building. She had to hold on to that.
