After that, it’s clear that the King surely knows who’s doing this. He might even be the one responsible.  How can you not tell us  ?" Despite her best efforts, the question was nearly pleading, begging him to disclose what he knew, to recognize the stakes at hand and to stop being such a (as Ron so tactfully phrased it),  tosser. Hermione wouldn’t stand for the demure, evasive attitude, the way Draco sipped his wine as if they were all quite beneath him.
