Zach laughed - laughed at Harry Potter, as if the words coming out of the other bloke's mouth were funny. And well, in a painful angry ironic way, it was. Harry Potter 'didn't manage everything'? He didn't do anything to make it worth it, anything to explain it, anything to make his huge failure worth it.
"One?" Zach asked rhetorically, "Did you miss the bodies all laid out in that last battle alone? They were our age, so many of them, if even! And perhaps it's slipped your mind how many people died while you were on the run - supposedly to save us all. But you didn't save us. Fucking Death Eater piece of shit - from what I've heard people say - Draco Malfoy did."
Oh he was really angry. "And maybe you and Weasley haven't hooked up yet," Zach chose to leave that vague, though he'd heard about Ginny, and at school it'd been obvious she had a thing for him, "But some of us have fallen in love before. Some of us lost someone before the fucking war you failed at decimated our Hogwarts class. Or are there so many lives you've caused to end you just can't remember anymore?"
