    By the end of the lesson, Hermione was the only one who had made any noticeable change to her match. Professor McGonagall made a point to show how Hermione’s needle had grown silver and pointed at one end, and Harry felt Ron vibrating with laughter next to him at the expression on the other Slytherins’ faces (particularly Daphne’s – she looked like she’d sucked on a lemon). Harry was a little disappointed that he definitely wouldn't be able to turn Dudley into a frog when he would be forced to return home.
