Cloud's brows knitted vaguely and he pressed his lips invisibly. What Zack was asking him was the part that he never lived to know, and as it was when he was cleaning up his office, he worried that Zack would ask him what happened to both of them in the future, to Aerith, and to everyone else they knew. And he didn't still know what to answer if the question ever did come up...
He had to check himself. He'd already slipped with Edge. "Midgar...was the closest place..." he could go to, he meant. Cloud wanted to say that it was the only place he and Zack could go to but he didn't go with Zack and he didn't want to lie to the man. "And anyway," he shrugged a little, "it's not like Midgar's the only place Shinra's got their eyes on. It's no more different than anywhere else."
