You think those are linked? [Hold on a moment. Jessie mentioned that the Fire Crystal destroyed the town it previously was in due to "experiments". Could it be...?]

Wait a moment. Since we all are supposed to have appeared with our own crystals in front of this one, they might be attuned to the magic of the large crystal. [He starts pacing in front of Yuffie.] And this dark and mysterious person has been stealing those over the past month, right? What if he were conducting his own experiments using our crystals?

[He stops.]

Maybe they also took this month's crystals as well? No, that can't be possible.

[After this, he continues muttering to himself.]
