"Kuja had prisoners here once. Zidane and some of his friends. The outer wards and security when I had arrived had been set to allow access only to a Terran Genome who could use magic, and Kuja mentioned once that Zidane was too stupid to use magic. I would be the only one remaining who could have gained access, other than by PINPoint or bypassing the system in some way."

Regulus is starting to wonder if everything is all right in there. And just what he's supposed to do with the pear core.

Mikoto, after a pause, finally says the rest of what she's trying not to think too much about after seeing the armor. "Zidane was the one who said Kuja was dead. He was the last one to see him. And he is a thief. Perhaps he could have gained access."
