Harry nodded some when Sirius explained what he was doing, understanding completely what he was talking about (he knew quite a bit about werewolves and their anatomy). Jalil, on the other hand, only licked his lips and stared down as Sirius worked. He would be able to stop the bleeding, but not fix him? Why have magic if you couldn't fix things completely? It just didn't make sense - none of it made sense. He was uncomfortable enough with the idea as it was, but when the concept that already didn't fit in his mind made even less sense? Well, now he was just frustrated.
He glanced away when Sirius pulled up the jacket to look down, out of modesty for the boy lying on the bed, but glanced back when he said that Remus would be fine. And he ignored the question about who he bit. "Thank you for your help." A quiet way of dismissing the two wizards.
