Madoka is so distracted with her snowballs that she doesn't notice the spell happening until it's already started to work. She lets out a small and startled "eep!" before looking around, only to realise she obviously isn't going to see all of them anymore now they're invisible..

But before she can say anything else, Madoka glances over in the direction of the cage and gasps.

"Tidus! Look, the way to the cage is clear!"

For the moment, anyway. It seems all of the elementals are distracted by some of the other fighting people, leaving very little in the way between them and the cage. There's no saying though when the elementals will start moving again though..!
