That really worried Asuka, and it clearly showed by the look on her face.  She didn't want Mizuru to have to go through that.  Asuka had enough basic understanding of her dark self, if only thanks to meditation and acceptance of her nature, but she didn't have to wrestle with it in order to be able to fight.  She looked back to Radar.  "Can I stop her?  Can I go over, put a hand on her shoulder and tell her not to?  Or is it already too late?  I don't want her to have to go through that for us."
