Monstrosity Kai desperate for one of the ninja to appear before him, desperate for one of them to appear and give him hope, desperate for one of them to save him, save him from the nightmare, save him from the horrors, save him from the hell he is in.
But most of all, desperate for one of them to save him from himself. Desperate for one of them to appear and make him see he's more than what he's become. Desperate for one of them to appear so he can just cling to one last shred of humanity, for their sake.
