Question: When Billy is walking down the steps towards the door he escapes through, the prison guard throws him the keys for the door. What would Billy have done if the prison guard didn't throw him the keys? What was his plan, or did he even have one?
Question: What has ended up with Max? Billy promised to go back and release him, but we never see that happen, and no explanation is given for that in the Epilogue. Is Max a real figure? If he is, what has happened to him? Did he manage to escape, or did he die in prison?
