The Riddler knows more  about the Waynes past.  How much will he reveal?

The question mark hovers like  a target over their faces. Implying  Riddler has secrets about  them all, including Catwoman

No one is safe from the Riddlers  target,  not even a crime boss like  The Penguin. Everyone has something  to hide (and lose) in Gotham

Quite possibly the most menacing and dangerous version of The Riddler to ever grace our screens!
