The panic added a copper taste to the fear, and the wolf howled loudly, letting the woman below his paws feel the sound that connected the sky to the ground. The sound echoes through the stone and the bares and Lupin closed the eyes in the wolf's mind and added his own note to the sound. This woman would never be allowed to hurt Sirius again, and she was never going to hurt anyone else. Her pride would never allow that to happen.
The wolf turned and looked once at Sirius before he lowered his gaping maul to that gaunt face. The furry head turned and he opened his mouth widely, letting Sirius see as her face was defiled, and his mouth was held open, allowing the infection to mingle with the wounds that would be scars. He tasted her, and the blood tasted sour and wrong, and they didn't like it one bit.
The wolf had decided it wouldn't eat her, and it just laid against her, letting the bite fester, and the wounds start to knit themselves slopply together. The two of them looked to Sirius, and a sound came low from their throat, a whine. He is ours, the noise said, he is ours and you live because of him. Remus hoped that she got that; she lived because her 'brat' wished it so.
