[The video opens with a familiar figure stalking down a crowded street; it's easy to recognize as Sirius Black, who looks only about twenty or so, though he looks pale and his eyes are bloodshot. He walks with an angry determination, pushing past people without looking until-']
"SIRIUS!"
[He jerks back to look and there's a plump man about his age walking towards him, tears running down his face. Sirius sees him and his face contorts into a face filled with rage. The other man stops about twenty feet away, and people around them glance towards the two of them curiously.]
"HOW COULD YOU? How could you do that to them? James, and Lily! They were your best friends And now they're dead and Harry's an orphan, all because of you-"
[Sirius pulls out his wand just as the other man goes for his; he points it at the other man and begins to shout a spell.
BOOM.
In a split second, the street is filled with a rising dust cloud, and people begin screaming; as the dust settles, you see Sirius standing in a large crater in the center of the street, with bodies everywhere. For a moment, he just stares at the blood spattered onto his clothes, and the tattered bits of fabric that lie where the other man had just stood, a severed thumb laying not far away.
And then he laughs. He laughs loudly and bitterly and without an ounce of humor or restraint, falling to his knees while everyone around him cries and screams.
