It's not a question of can he recover his balance, it's a question of how long he can hold out. He couldn't even swing a practice sword right now, forget the behemoth that's the Buster, hidden away in some storage locker. Kunsel's going to become their only line of defense on the way out. Which means Zack's going to have to carry Cloud.

Not like he wouldn't do it anyway. When they don't move he follows Kunsel's gaze, eyes shifting from the card to the computer, then to his friend. He knows that look. Even six months removed from the world at large, Zack knows that look and a half-smile curves across his face.

"Let's try it."

He doesn't feel the slightest bit sorry about what Kunsel's going to get up to on that terminal. Not for Hojo, not for who worked with the "good" doctor, and not for ShinRa. If Kunsel wants to wreak havoc, he won't stop him. A little more chaos would be a good idea.
