They had found Quirrell, Lucius had told her, that same evening they had rescued her, and as he descended into the cellar, they had been waiting.  They had only assured her she no longer had to fear him coming after her again, but they wouldn’t provide details on what they had done to him.  Frankly, she didn’t want to know.  She was certain it had not been pleasant for Quirrell.  This time, she knew, he would not be coming back from the dead again.  Good riddance.
