Harry threw himself down onto the ground and plunged his hands deep into the numbing slush, searching desperately. But it was no use... he could not feel his wand anywhere. He looked up in desperation, his hands still moving through the snow, beginning to as though they were filled with needles. Greyback had leapt onto Lupin, who was howling in pain from the wound in his leg. Greyback's dripping fangs were now only centimeters from Lupin's grimacing face; an evil grin lined with rotted and razor sharp teeth. His mouth opened wider and he lowered his teeth over Lupin's quivering throat, saliva dribbling onto the less powerful werewolf's robes. Harry felt a tear sqeeze from his eye as he looked away, unable to bear the sight of losing another friend.
"PETRIFICUS TOTALUS!"
Harry's eyes opened immediately, the stream from his tear freezing on his cheek. He looked to the cliff edge, where Lupin still lay helpless under the weight of the enormous werewolf. Lupin's face was one of shock and disbelief - he had not performed the spell. Greyback rolled helplessly off of Lupin's chest, his arms and legs still in a wolf-like position as he stopped on his curved back. Tonks rose from the ground near Harry, blood seeping from the bandages on her forehead, wearing a look Harry had never seen on her face before - total and uncontrolled fury. Harry backed slowly through the snow, his hands still numb as they swept through the slush, finding ground for him to move away from the battle. For the first time in his life, Harry found himself afraid and in awe of what Tonks might do.
"You sick, filthy bastard," she rasped as she approached Greyback's defenseless body. Fenrir's expression was frozen in time; eyes open wide in a look of fear and surprise, much like the expression Lupin had worn seconds ago. Lupin now struggled to stand, his stiff leg not allowing him to accomplish the task very quickly. Tonks was almost to Greyback now, her wand still pointed at him menacingly. Harry was reminded momentarily of the expression on Fred and George's faces as they approached their parents' murderers - a look of cold indifference and duty. Harry found himself faced with the knowledge of what was about to happen before it was done.
Her muddy, wet cloak flailing behind her, Tonks reached forward with unexpected strength, and grasped Fenrir's tattered shirt. She lifted him slowly upward as far as she could manage, and bent down so that their faces met. For a moment she merely stared him in the eyes and Harry waited for her to say something. Her eyes bored into his with a look of utter loathing and contempt. Without saying a word, she tossed his body to her left, directly over the edge of the cliff. Harry crawled forward in a rush, slipping on the snow and falling onto his chest. He watched with mixed shock and horror as Greyback's rigid form struck the edge of the cliff, and fell tumbling out of sight. Tonks watched Greyback's fall from the edge of the cliff, her expression unreadable. Lupin slowly approached her, limping painfully and reaching out to her. She turned and met him, embracing him and sobbing tearfully into his shoulder. Harry tried to sit up and move his hands out of the numbing snow, but instead sighed wordlessly and fainted into the soft bed of snowflakes.
