The rancid smell suffocated him the instant Voldemorts hands neared Draco's nose. Perhaps it was just another defence mechanism for the Dark Lord, if someone ever did get close enough to throw a well aimed punch or knife to the gut, the smell would choke them to death before they could even have the thought. Draco's head swam with the smell, all thoughts consumed with how to get away from it as quick as possible, he didn't have to wait long.
