Sorry mate. I don't get it either. Are you talking about how Sirius was a dog and therefore destined to be killed off in the story?? Or are you talking about that 'classic technique' that is used in thriller and horror stories? Where the hero and bad guy fight it out and the hero wins and slumps to the ground. When their backs are turned, the bad guys' eyes spring open and, with the last bit of hateful life, they reach for the gun and.... hero cops it too! Therefore, just when we thought everything was fine.... hero dies!! Are you suggesting that this is what happened to Sirius adn MAYBE what will happen to Harry??
