When 9 first comes to life, he finds himself in a post-apocalyptic world.

Despite being the neophyte of the group, 9 convinces the others that hiding will do them no good.
A boy, waiting for a bus. A dog, begging for potato chips. The boy sends the dog away, violently. He sees a hangnail on his finger and shows us, graphically, why you should never pick at them.
