Luka's quiet as the two exchange words, thinking on the Wizard's revelations that morning.

"The Wizard told me last night that we'd be meeting the person responsible for sending us back in time today." He speaks up at the lull in their conversation.

"And this morning, she confirmed that this... person... is locked up somewhere, causing those cracks, trying to escape. I think if they escape, the world's going to end. Maybe that strange voice was them."

He doesn't know how much either of them know about the situation, but Luka figures it couldn't hurt to tell them what he's learned.
