It's a simple enough explanation for Duster to understand. It's not like he understood how PSI worked, just that it did something for some reason. He lifted the crystal he was holding in his hand and looked deep within it. While he had seen glowing crystals before, this one felt...special. Like it really did have magical properties. How it could change his clothes, he would never understand.

Subconsciously, he lowered his hand to stuff it into his pockets, but realized something: "My things!" He patted himself down. No Thief Tools. No Egg of Light.

He was screwed.

"Where did they go?!" He turned to his Moogle, who shrugged.

"I dunno. Why don't you ask Dr. Cid about that?" Tamekichi turned to Yuffie this time. "I heard he can bring back your old things, right?" He only heard the rumors from other Moogles, but it would be great it another Hero confirmed it.
