"I'm not from Gotham."
Schiller's first rule of making things up: nine parts truth, one part lie—or nine parts lie, one part truth.
"I came from a place very far away. Batman and I only met because we both traveled across universes at the same time."
"That place is so distant it lies beyond the imagination of time and space. It cannot be reached by any conventional means, and I am here only because Batman invited me."
Peter's voice echoed through the empty lower level of the Batcave. Batman said nothing, because he too wanted to know exactly what Peter's plan was.
But he would soon regret that decision, because Schiller's second rule of making things up: anyone can be wrong, except me.
Batman had made that decision because he already had a plan, and every one of Batman's elaborate plans began with the Joker's schemes.
Peter's mind spun at high speed, linking together every clue he had learned. Alongside his own interpretations, there was also a certain amount of fabrication and association.
Because Schiller's third rule of making things up: besides being rigorous, it also had to be exciting.
"Before I came here, this city had just gone through a period of chaos. The culprit was, naturally, the infamous supervillain Joker. He obtained a drug called Titan Toxin and claimed he would use it to destroy Gotham."
But aside from Batman, no one knew that all his fanfare was merely a cover for another sinister plot.
Sure enough, all three people in the cages frowned. Jason had not even realized that he was continuously leaning forward, listening to Peter with excessive attention.
Peter relaxed slightly. It really worked well. Schiller's fourth rule of making things up: don't lie—just alter the way you tell the story to create enough suspense.
