S2, E18: When Nick Knight fails to save a girl from death at the hands of hoodlums, he becomes consumed with guilt, knowing he could have prevented her murder if he was willing to use--and reveal -- his true "vamp" powers. But guilt is an enemy to vampires. The emotion becomes a disease that distorts all truth and reality, building a world of its own. Caught up in this distorted new world, Nick must find his way back to reality before he becomes the victim of his own emotion.
