Mephisto wondered if his plan had been leaked. "How did they find it? No, it doesn't make any sense. Only three Devils knew about it, and none of us would have let our lips slip. None of us would gain anything from it." Mephisto continued to ponder. "Could it be something happened in the Heavens?"
He quickly turned to his subordinate and gave his orders. "Investigate! Find our spies in the Angels' Realm and see what is happening."
"Yes!" The subordinate quickly nodded and left. Still, he found it would be quite hard since it was pretty much impossible to put a spy in the Heavens. The reason for that was obvious. The Angels were just too united for the sake of their races. Even Mephisto could probably count on his hands the number of spies he actually had in there, and that's because they were not angels.
That escalated fast. xD
