the Riku clone died in CoM, HOWEVER it is possible that the Organization made another clone of Riku, which i doubt. i dont think its because he is blind, or to develop his other senses because he takes off the blindfold in the DD video. im wondering at the unlikely, yet possible theory that i thought of. My theory: considering the fact that u never see his eyes, i wonder if something happened to him, and he has a scar that he doesn't want anyone to see, but he takes it off when he feels that his friends are in trouble. in my pic of Riku in my sig. it looks to me like hes not wearing a blindfold, but his hair is shadowing his face. i was trying to get more evidance to back this theory up before i posted it, but i have none, so dont get mad!
