So, everything started at Akham. You were Joker's therapist, you fell in love, he... somehow too? And then it went on and on, you'd do anything for him. So, you killed the guards at his cell and became his precious queen of chaos.

After five months, a report was on the news, You're missing, well.. sure. Of course you're missing! Nobody knew that you're in a isolated prison for psychopaths. Just Joker knew about it.. and tried to break you free, he'd do anything to get you out of there.
