Proud arrogant Slytherin! Wouldn't take help even if he was half dead, which by the look of those wounds, it wasn't far off a guess. After checking the area twice and once more to gathers his nerves, the eyes shimmered and rose up to where they stopped, staring into the fire. Eyes that were still haunted watched the flames lick the air.
Coming forward, he knelt beside the sleeping potion master. Taking a burrowed wand from his pocket, the kneeling man put out the fire, gathered up the broken wand and took one last look around. "You're not going to like me," he murmured as he cast a minor sleeping charm. A search of his pockets produced a long thin chain which he hung around Severus' neck.
"Fare journeys" Sirius muttered as he let go of the chain, watching as the other faded away. The wizard at rhe other end of the portling would apparate it back to him in a moment, so he could follow. This would be done over a dozen times over the night, to throw of any chance of pursuers. Portlings were a pain in the neck.
But were untraced by the ministry. Such were the trials of a hardened criminal.
