Like when Rodolphus would try to assault her mind again. She wasn't naïve enough to believe that he would give up after one failing, especially not after he declared that he would try again soon. If he was aware that she left in the middle of the night to go somewhere away from the estate, he didn't confront her about it. Maybe he would in time. Only one time did he enter her bedroom the afternoon after she'd returned to check on her. She pretended to be asleep and he left after just a couple of minutes.
