"You don't want.."

Her voice trails off, and she gasps at the realisation. Because Piccolo doesn't want her to stress, but.. it's too late.

She's already stressing.

Madoka's jaw drops at that a little, but then she quickly closes her mouth again as she tries her darnest to look more determined.

"O-Okay! Got it! I.. I'm not stressing!" Or so she says, clearly with the voice of someone stressed right this very moment..

(At least she is still moving and therefore focusing on their current task?)
