Nathan, whose special power is immortality, has been buried alive but he is rescued after a mysterious masked and hooded figure sends Kelly a paper dart reading 'Go To His Grave'. Shaun, a new probation officer, laid back to the point of boredom, arrives and takes the group to help at an art therapy class for the emotionally disturbed where Simon meets Lucy, with whom he was once in a psychiatric unit. She is a shape-shifter, who morphs into each group member to tell them that Simon killed Sally, hoping he will be put back in the unit with her. However, since she loves him, she keeps his secret, though it is now common knowledge to the other misfits, who dump the corpse in the river, watched by the masked man.
