There is one person who's not worried about Cloud getting sick on him but he remembered that the kid got motion-sick. When he found the blond on the deck, he made sure to stay upwind so that at least one of them wouldn't feel guilty about it.

Zack leaned against the railing and looked out on the land below. This wasn't quite the flying he wished he could do but it was still pretty nice. Better than ShinRa helicopters anyway. It felt a lot more like freedom this way. After a moment of just enjoying the view, he finally turned towards towards Cloud.

"Hopefully we'll land soon. Maybe you'll feel better than." He remembered how Cloud was in Junon.
