Whoa, look at where they caught Wangji! It's interesting for Tidus to witness where the two see, and he gives the impression to both the kids to look around for him, so he can see the rest of the class. ... even if Madoka might get shy about that, but he's curious! The only other foreign school he's seen is his fake memories of Diagad!

But it's a brief thing, their reason for being here not lost or forgotten by Tidus. And he speaks, though mainly to the pair - it's always hard to tell when and if he can be heard by those they're rescuing:

'Let him say goodbye to everyone. He might have some stuff back home to sort out.'

They can wait half an hour, can't they? The situation feels desperate, but he doesn't want to worry or panic anyone when they don't need to.
