He stands, stoic and still, as he is accused; yet inwardly, he smiles. He feels no guilt for the small part he played in Black's downfall and in fact, his only true regret is that he could not commit the act himself.
He would have wished nothing more than to feel his enemy's blood slip through his slender fingers, and hear his last gasping breath before he descended into darkness. He thinks perhaps it would have been the greatest sound that he had ever heard.
Still, he considers, he is honestly quite content in his knowledge that the world is rid of the man…that he is rid of him.
He laughs, finally, and walks away from Potter's startled form, fading into the distance and marveling at how very wonderful his life is, for the first time in years.
