Hey look, there it is again in the one I’m at now. Hermoine to Potter: “What’s wrong with your hand?” Potter: “Nothing.” (This was the Dolores torture). Hermoine actually finds out, which is refreshing. “You’ve got to tell Dumbledore.” Harry: “No. Dumbledore’s got enough on his mind right now.” Freaking stupid, Harry.
This “is anything happening?” “No, nothing.” exchange with Potter is constant in this series.
Nobody ever explained anything more than the likes of “Voldemort’s back! You have to believe me!” If anyone actually gave account or explained anything at all, the good guys would have a lot more allies than they do. Hell, actually talking is how they convinced a bunch of people to let Harry teach them dark arts defense in Order of the Phoenix. It seems that actually talking is how every good event happens, and that not talking is how every bad event happens.
