"'That's an idea . . . You,' said Ron. 'Teaching us to do it'" (ch. 15).
Harry had gotten used to teaching the DA – had even started to like it. Teaching seemed to come naturally to him, especially Defense Against the Dark Arts.
Every now and then, Hermione and Ron would shoot him smug looks, as if to say, "See? We told you so."
But somehow, even though his temper was so short these days, he couldn't get angry about it. The DA was his only outlet, the only thing that really made him happy anymore. And it was all thanks to Ron and Hermione that it had happened.
How could he blame them for that?
It's sweet how much faith Ron and Hermione have in Harry, and how they stick by him no matter what. I love it.
