She didn't. Since she was removed from her broom cupboard and forced to come face to face with the monster who would become her master for twenty years, she'd been afraid to speak so openly. Talking about the Dark Lord dying seemed to her to teeter on the edge of outright blasphemy. Hadn't he proven himself incapable of dying? While she felt differently months after she learned that he could die, the visceral reaction to having someone mention his mortality and fallibility was still present. It was something she didn't like to consider. Over the years she'd turned in countless enemies of the regime for saying much less. No matter what Rodolphus claimed, she just couldn't imagine that she would've ever willingly had a conversation with him, in bed or not, where they talked about the world after their master's fall.
