I am pretty sure Kaito would just Psyduck all over the place. H-HOW IS THIS POSSIBLE, AOKO IS KID, THIS DOES NOT COMPUTE, WHAT IS GOING ON HERE? He would be incredibly angry at the Black Organization for killing another person, especially since that person was Aoko, but he would like. Not know how to deal with a Kidoko at all. THERE WOULD BE FEELINGS, about her being dead and about him not being Kid in another universe and it would just. Take some time for him to get used to things. But eventually he would deal! It just might take a while of him wading through feelings first.
