Beware the nice ones
By Byakurgan
Book by JKRowling and company; Story by me.
Beware the man who cannot laugh, who sits apart from others, in the shadows. Whose eyes shine in the darkness. For hatred is in his heart for all he sees, and deep bitterness. He will follow you into the night, and murder you in a dark alley, and not even take your coin. Beware far more the man who laughs too easily, when others would be sober. Who stands in the center of the crowd, merry and bright. For in his heart burns a terrible anger, hot and perilous, that he may not even know is there. But when that anger comes forth all who stand with him will sorrow. For the man who cannot laugh has a disease in his soul, and the man who laughs at everything holds madness in his eye.
People looking at a smiling fellow never expect the blade he so easily draws through their heart…
Harry gaped openly as he looked back and forth between the Weasley twins and the smoking spray of gore that had, just moments before, been the mighty Lord Voldemort. It was hard to imagine that the brothers would be the ones to thwart the prophesy, but here, only moments before, they had done it.
Months ago, when Harry had begun his hunt for the Horcruxes he had approached the two geniuses on a whim, hoping for a manner in which to track down the fragments of the Dark Tosser's soul and had told them everything. He had been dumbfounded when they had immediately taken him, Ron and Hermione through the Hogshead in to the room of requirement and retrieved Ravenclaw's diadem for study. Hadn't the twins mentioned using the room to hide things once before? He had also told them of the wig and circlet beside which he'd hidden the Prince's potions text, but it was no matter. Fred and George had vowed to destroy if for him and Harry had left once more to search for the remaining two items.
But that hadn't been all the twins had done. Armed with the knowledge of what they were up against the twin terrors had crafted an enchanted glass marble that fed on the instability within Voldemort's soul, using the fragment in the diadem as a base and had quite literally caused the man to explode, his own magic tearing him apart from the inside out.
Dusting off their hands as if they had done nothing more than swindled someone at exploding snap or pulled off a simple prank the pair turned on Harry. "Mr. Potter," they said in unison "I do believe you promised our sister a relationship once dear Tom was gone for good. We wouldn't want to disappoint her now would we?"
Harry gulped.
