Bod increasingly wants to have relationships with the living and slowly realizes that the dead never change and grow up. Being a living boy, Bod grows up and changes his likes and opinions. The dead remain the same age as when they died at for all eternity. As Bod grows up he learns that he can make a difference to others, and he begins to take actions to positively affect those around him. When he learns that his biological parents were killed by a man named Jack, the seed of revenge is sown into him. That seed first appears when he goes beyond solving the school bully problem to punishing them further to get back at them. His revenge reaches its peak when he kills four Jacks in the graveyard and ends the Jack that killed his parents by using the Sleer as his weapon of revenge. In the end Bod realizes that he needs to leave the graveyard to fully live, knowing that one day he will return to join them again.
