Did Nomura plan Xion before he planned to make KHDays?
I've seen people who've said that Xion, or something like her, was planned since KHFM because of what appears to be Xehanort sampling Sora's memories at the end of the unknown boss fight.
Though in KH2 I feel that the implied relationship at the end with Roxas and Namine is a little strange and seems almost forced if you consider Xion being a thing in Nomura's mind.
So what do you guys think? Any evidence you think I'm missing that proves/disproves it?
