"The Waynes and the Arkhams, Gotham's founding families, but what is their real legacy? Twenty years ago, one reporter set out to uncover the dark truth. He found shocking family secrets. How, when Martha was just a child, her mother brutally murdered her father, then committed suicide and how the Arkhams used their power and money to cover it up. How Martha herself was in and out of institutions for years and they didn't want anyone to know. Thomas Wayne tried to force this crusading reporter into a hush-money agreement to save his mayoral campaign. But when the reporter refused, Wayne turned to longtime secret associate Carmine Falcone and had him murdered! The Waynes and the Arkhams, Gotham's legacy of lies and murder! I hope you're listening, Bruce Wayne. This is your legacy too, and Gotham needs you to answer for the sins of your father. Goodbye."
