Katsuya does nothing but grin. He didn't technically see anything- not in real time anyway. But after a bit of jogging they'll start to finally see that fire cage. That's exactly what he saw!

And-

...Oh, bugger, he never got a look at what was in the cage in his 'preview'. "...Wai' tha' ain't-"

It takes half a second before he realizes it's because the rabbit- as Tidus spies- is not the thing that's caged. "OH! There! ...And uh...Well, there's somethin' in th' cage there tha's for sure..." Some kind of...dog..?

He's not really sure about getting too close just yet. "...We should prob'bly help w' th' cage b'fore th' rabbit huh..." he sighs.
