When Hermione was informed that she would also have to enter into the bonds of matrimony with another loyal Death Eater, she was incensed. Not only was she afraid that she would be less valuable to her Dark Lord's eyes when she was filled with some bastard, but she didn't want to be paired up with just anyone. Her protector had had the same idea. He wanted to offer what sanctuary to her that he could. He'd pled his case to the Dark Lord. Begged him to allow him to set aside the wife that abandoned him for Hermione.
