Neither did Kefka, really. He was saying whatever he thought would get her to talk and keep suspicion off of him. It seemed to be working fairly well so far, even if the act of asking the question to begin with had nearly blown his cover (really, did the people here have to be so stupid?).

He stared at Neirenn in confusion as she asked about the "other spell," wondering what exactly she was talking about, and as he realized she meant his illusion, it took every ounce of self-control he had to keep a look of shock off his face. He just needed to relax. She hadn't said a thing about illusions. All he needed to do was lie, lie, lie. "Just something to keep a spring in my step as I go along," he told her. "I woke up a bit tired this morning, you see."
