That might have been rash, but Ginny isn't the only one losing patience right this minute. Ron's face looks like he was hit by a Bludger and Harry's bright red and stammering out excuses. But Hermione can't be bothered to coddle the two boys" sensitivities. It's time to grow up. Insisting Malfoy is a Death Eater is absurd. It's occupied the better part of Harry's year to a detrimental effect, and Hermione's had enough. Dumbledore's given him something important to do, and he's still too busy fixating on Malfoy to do anything about it.
