Antonin had to physically drag her up to her attic bedroom to go to sleep more than a few times when she was stuck obsessively practicing a new spell. He would take her wand away, spell the door locked, and promise her that he would release her only once he was satisfied she had gotten some sleep. Later, her annoyed husband would steal her books and demand she either come to bed or leave the house for good. Once or twice she imagined that wasn't the worst of fates. Certainly since running away she'd discovered that the illusion of a happy family was more difficult to bear than the reality of a harsh life on the run.
