Rodolphus was up to something awful when it came to her. That was all that she was certain of. Until she uncovered the reasons why he manipulated her mind, she didn't think she would ever be able to rest easy again. There would always be that lingering fear that something would trigger a change she had no control over. She'd learned enough about mind control to know that it wasn't a crazy science fiction that should just be ignored. If Rodolphus somehow implanted a spell inside her brain that could activate something, she would never feel like her nightmare was over.
