He let out a strangled hiss, wanting nothing more than to rip off the hands molesting his friend. his eyes traveled over to blaise and neville, shocked to see that seamus was beating the snot out of Neville, in front of blaise. he growled low in his chest and he could feel his body tingling strangely. he felt like he was going to burst out of his skin, and he could see red. He started thrashing in Pansy's grin and she tried desperately to hold on, but Harry was growing stronger and he had fury on his side. He broke free from her, turning to face her and ripping claws that had sprung from his fingertips across her face, leaving her screaming in pain and outrage as she dropped to the ground clutching at her wounds. He spun around again to face a stunned Ron and crouched down to striking position. Harry was running on instinct now and he opened his mouth and his voice rang across the lake creating ripples in the water. He was singing a siren song, and it was going to summon Draco's favorite pet.
