He wants to dominate Katy

Katy gulps as Frost speaks, she didn't want to fight him as their fights came down to physical fights and she was pretty tired from her workout so far. Frost seemed to know this, maybe even planned this as he smirks and whispers to her "We are going to have some fun, you will do as I say or the people in this gym will learn what frostbite does to such bare skin" he says looking around at the men and women in shorts and shirts that exposed quite a bit of skin. Katy knows she can counter his powers, but trying to block his powers from targeting civilians was tricky when also fighting him, she would need to play this carefully.
