Soooo... concerning the story : where Xehanort is in possession of Terra's body still marked by his affection for Riku and with malicious intent at the beginning, abducts Riku for his plans. But he ends up raising Riku as his own child and develops a strong bond with the child, acting truly as his father.

After some years, he is separated from Riku because of the failure of one of his experiences, which dooms him and provokes the loss of his heart with him being engulfed by his own darkness. Both him, as he finally totally succumbs to the darkness, and Riku lose the memories of their happy years together.

Years later, Xemnas meets with Riku and they both start to relive some memories. Confused by the antic affection, that was purely paternal, of Xehanort and Terra, Xemnas develops tender feelings of an other nature for Riku, without being aware of the purely paternal relationship between him and his « past selves ». The feeling is absolutely not mutual and Xemnas is very conflicted because of the influences of Xehanort and Terra, who remain like some non-physical "counterparts", alter ego.
