this has been puzzling me sometime and not even kh2 was able to answer some of my questions. I know what a heartless is but when one is killed, does it's heart return to the normal person it once was? Another question i have is about the nobodies, i know it's made from the body and soul left behind when a strong hearted person is turned into a heartless, but is the nobody literally the body and soul or were those two just ingredients to make the nobody, cause i was wondering about sora. if roxas was his nobody and sora returned to normal, how can they both exsist if roxas is sora's body and soul left behind and sora still be normal and have his old body? i'm just a bit confused about this whole concept.
