Zidane did have a few question - maybe a hundred questions - but he didn't say anything. Staring at Kuja, one brow raising at the suggestion of punching him (which maybe it was at some point?), he refrained from doing so. But he did approach after the flower crown came off, and raised his hands...

... and pinched both sides of Kuja's face.

"Yup, you're really here."

They could circle back to that whole 'made it out' thing in a second.
