Spoiler alert before you read if you have not yet read the comics.

At the end of issue 92, the Designer states to Batman "Hello Bruce, Please come in, we should talk a little before I kill you."

We then find out that the Designer is just a corpse of a villain being controlled by the Joker's strange gas, so the question is about the gas and how it works?

Is the Joker now aware of Batman's secret identity form the comment above? We know he has drained Bruce Wayne's account, but that was in the Designer's original plan, and finally why does the joker want the Penguin knocked off?
