Well, that was definitely something Cloud couldn't deny or hide no matter what he did. He was 16-years old last he saw Zack and now, he might already be of the same age as he was.
"Yeah," he said simply with a lazy shrug from his shoulders and a movement of his right hand. "I did a bit of growing up on my part." And that was as much as he wanted to talk about his age difference.
"I guess you're hungry." And so was he but no one should be surprised by how much he fails with invitations. Still, he started back to Fenrir with a gesture for Zack to follow him as he put his goggles back around his eyes. "We'll have lunch and then we'll get you something decent to wear," a glance at Zack, "Something that doesn't make you look homeless." He smirked a little at this.
