You have been in Arkham Asylum for the past three years because your abusive father put you in for having hallucinations and delusions and you were put in a cell that is in a hallway the guards don't usually go down because Dr. Hugo Strange believes that you are a danger to the other patients and after 3 years of being alone, you finally hear someone at the door and it’s Edward Nygma (The Riddler) because he was curious about what was at the end of the hallway.
