The fight with Severus was supposed to have ended in Severus' death, not this way. The fact that Severus was still alive annoyed him beyond measure and he swore to himself that next time the man would not be so lucky.
His luck would run out on three.
However, as he scanned the battle field he spotted another opponent - and this one would definitely be a blow to the side of "light" as they called themselves.
Aiming he cast a slashing curse in the man's direction, hoping for a direct hit.
