Another evening. Having just finished dinner and preparing to return to his dorm, Arkham Batman was stopped by Main Universe Batman. The two walked side by side down the corridor. Main Universe Batman turned to look at Arkham Batman and quietly asked, "Don't you think Owlman was acting a little strange today?"
"A little, yeah," Arkham Batman said. "The way he looked at you was off. His aggression was too strong, and he even dared to look at me twice. That's not normal."
"What do you think is wrong with him?"
"Looks like your plan to send Iron Man to interrupt their studies didn't work," Arkham Batman said. "He definitely learned something from Schiller... Wait, why would Schiller teach him anything genuinely useful?"
"That's the problem," Main Universe Batman said. "Owlman thinks the special power he gained came from Schiller, but Schiller isn't a mage and doesn't understand contracts at all. So if Owlman truly completed the contract, how did he do it?"
"Schiller may not be a mage, but he has a good relationship with the Sorcerer Supreme. It's possible he knows those Demon Gods. If he acted as an intermediary...

"We'll find out if we test it," Main
