From that moment on the torn area of his sweater and the blood marking on the white t-shirt continuely change shape and size. And if Stripes claws were sharp enough to cut him that bad then how come it didn't cut through his white t-shirt under his sweater. Because Billy showed alot of pain when he was clawed.
