I made this thread to see if I can get an explanation for Xehanort's plans in BBS and DDD mainly because I'm still a little hazy on some of the plot points in DDD. In BBS he created Vanitas to fight with Ventus so as to have a heart of pure light and a heart of pure darkness fight to create the X Blade. That plan didn't work since Ventus destroyed Vanitas and caused his own heart to fall asleep. Then in DDD he comes up with the whole 13 darknesses and 7 lights. My question is why didn't he try the BBS plan again and if the DDD plan is better why go for that one?
