he had an injury and acquired a disease that is normally controllable by the immune system, but he has a genetic discrepency, so the warts kept growing, and unable to be affected by his immune system, they became so misformed that they look as if they are wood...i'm so surprised he's still living, like how much pain he must be in and how much the disease has taken hold of his body...
damn..
