Rodolphus didn't sound angry. Perhaps slightly annoyed, but not angry. Once upon a time she thought she knew how to handle him when he was in a similar mood. Little did she know that he was always in control even when it didn't seem like it. Hearing his voice again after discovering what he'd done to her filled her with more dread than any other emotion. She wished Antonin was home. They made a good team. Being alone against a formidable enemy was never desirable.
