Vergil didn't respond openly to Kari's demand that he see her after classes, but he did file away the information all the same.  Hearing Miki continue to prattle on, which he ignored for the most part until she mentioned the marks on his back, to which he stiffened visibly but he didn't say anything to it.  Having the nurse look at them was the last thing he wanted to do.  Despite her attempt at comforting him, Vergil didn't say a word, simply taking another drink from his soda and then starting in on the candy bar without even looking to see what it was or to even register the taste of it, Miki's words doing nothing for him.
