If you have played the previous Dissidia you should understand that their memories are locked and they were taken from their timelines without their knowledge. As the stories progress some regain fragments here and there. I love NT maybe SE would do something and perhaps we can be tested to battle only to be defeated and rejected, giving some kind of shard to get minions ( moogle version of Dissidia) or gear based those characters. I would love Kains or Kefkas :P I would love to see a Kefka laughing emote O.o/
