As Vrishchika vioces her suspicion about the intelligent butterflies, all the color leaves Nala's face. When she clarifies, the color starts to return slowly, ever so slowly, but not entirely. It's a moment before she can speak. "And we risked that?" she says, with more horror than accusation. She looks down at her hands, which were almost shaking. "Only if you use them more than once...we have to assume that means round trip. I don't feel any different," she mutters rapidly to herself. She closes her eyes briefly, heaves a sigh and puts her hands down by her sides again. When she speaks again, it is in a level tone. "I would rather race them to the other oasis on foot than be altered by this thing. This potion you speak of. If you aren't absolutely certain it's going to work..." she shakes her head."Then no. I will still do my best to help, Froad. But will not risk what I am for you."
