ok I have a theory why sora dint remember any memories from castle oblivion namie said to sora that he (might re call theses memories to the surface). the reason he dint remember is because xion was attacked by roxas who forgot about her and in the enemy files in roxas diary says xion's ultimate transformation. (sora's memories from each world multiplied her powers) technically castle oblivion is a world roxas really doesn't remember any worlds that sora has been to before he went to those worlds. so since roxas attacked xion those castle oblivion memoires were gone. but image if sora did still have those memories that would mean we would have all are abilities form re chain of memories maybe sora might get them back. slowly piecing them together that's one reason im so hype for kh 3 imagine doing the rage storm sleight or doing friaga burst. thanks for reading this but remember this is only a theory. :smile:
