Cloud had hit on the one thing that Zack would not question. After nearly a year of caring for his friend and seeing the state Hojo's experiments had left the poor kid in, Zack wasn't about to push any harder when Cloud brought up the effects of the mako. Zack settled back in his seat and nodded.
"Okay. So you made it to Midgar somehow. What next?" Zack had his suspicions, but part of him wanted to believe that once he'd disappeared, the Shinra troops had given up and walked away. He'd hidden Cloud somewhere relatively safe, after all. Maybe the ground troops had missed him. Maybe they'd been so surprised by Zack's disappearance that they forgot about everything else but finding him. Maybe. Or maybe not.
