i know im probably wrong but i think i know wat it means in the kh2 secret video when it says memories of exhanort, in the end of roxas's part, when u draw the picture on the table in the library, it's 3 symbols, the heartless symbol, the nobody symbol and a different symbol (i didn't get to see it though, so if it's a known symbol tell me please) wat if that symbol is a 3rd ememy, 1 made out of memories, if this is true it mean will have to kill him Again!!!!!!!(how many times is the bastard gunna come back) it could also mean wats left of exhanort in riku. if u find anything wrong with my theory tell me please.
