Should have had Batman figure out the floor map.
Riddler didn't stop at Falcone.
He made detailed records of wrongdoing for everyone in Gotham.
He was going to kill them all.
And use everyone outside Gotham to do it.
As soon as he realised that, heavily swayed by the information. All of it useful. He also realised he was the plan. If he kept all of this, it would be him that did it. Joker's sidekick. All of it could prevent...
All of it could have wrongs intercepted. People prevented from being invalid.
Before he thinks he burns it. All of it. In the building as it burns.
The outside let in seeing itself better would treat them as if they did all that for eternity. They would keep them that.
Riddler appears.
"You're just like them."
"What about the victims."
Batman says: "We won't make them."
"Victims?" "What do you call a repeat offender?"
Batman answers: "Potential."
A hole is burnt open by a collapsed wall.
"It's warm in here."
"It's cold out there."
