After her wedding -when all bad guys got took back to Arkham- it's up to Spade to get them all back, but how?
She needs to start living up to her name, Spade Ace Quinn, and as her reputation as Joker's daughter, with the help of Jonny Frost and her only villian enemy Lex Luthor -who she would battle in Metropolis- Spade is willing to get back Kenton and the others.
...And possibly sacrifice her sanity to become even more Crazier than all of them, even Joker.
