"Can't you know where they are without working with them? I can hear where wasps are without climbing right up into the nest. You already know they're gonna betray you." He was concerned, not only because of his difficulty trusting Kuja, but also, hadn't Kuja had enough of dealing with people like that all the time?

Selfish, greedy fools who just want power.

Kuja had wanted power, before he'd known he was going to die. If he hadn't started worrying about being mortal, what would have happened to the people of Gaia then? Zidane was willing to bet it wouldn't have been great. And it wouldn't have involved Zidane living a long and happy life.

"You're gonna tell me all about these evil people, right?" He frowned, then paused. "I won't make friends and lie to them, not like that. I'll be honest with the people I meet."

He wondered if Kuja really wanted to work with him. Kuja had saved his life, that he knew, and that was something, a big something. They were both Genomes, and that was something else. "What are you loyal to, in your heart?" Kuja had brought it up, and Zidane was curious. He realized that Kuja wasn't necessarily going to tell him the truth or even answer, but it was too late to worry about that; he'd already asked the question.
