Zim falls into his insane state and hunting Dib down. Until he manage to corner Dib to a wall. Dib holding a knife for protection warning Zim to stay back since he doesn't want to hurt him. This is one of those situations that there is some left of Zim deep inside and Dib knows but is hoping to save him instead of killing him but would he have to to save his own life in this moment, I guess it is all up to the viewers imagination of what will happen.
This isn't a chapter but a fan art of IB, it did took me awhile to get it just right but I am happy how it turn out.
