Eventually, Robin finds blueprints and plans along with a number of lists and files; collecting them in and finds out that the plans are labeled "Arkham City" to his confusion. Robin leaves after collecting the evidence required and contacts Batman, so the Dark Knight claims his done talking with the mayor and leaves too.

At the Batcave, Batman and Robin search through these plans and Batman is confused until he found a tape, playing it on the Batcomputer. It is revealed Carmine Falcone is indeed partners with Grange, with Carmine sending a message claiming that the plan is set and currently in building thanks to both Grange's authority and funding.

Batman returns to the mayor's office while Oracle and Robin look at the evidence, with Batman angrily confronting Grange with the tape recorder he found and some of the plans. Grange reveals his true colors of a corrupt official by revealing his dealings with Carmine and even his involvement in the Waynes' death, having Carmine take care of it by hiring Joe Chill to simply get him out of the way of his plans. Batman angrily attacks the mayor but stops upon hearing security and Batman escapes, warning Grange that he'll stop him. Grange then calls someone, saying Batman is going to be trouble.
