Relating to the R=U theory;

According to the future, Squall as Ultimecia's knight, they got on so well to each other, Squall has been protecting Ultimecia for a while. Eventually Squall and Ultimecia have fell in love naturally. Which shows that the present days were slightly affected by the future.

It does make sense, I mean if it's true that Squall doesn't care about Rinoa in the first place, then why did Rinoa keep having interest in Squall without being realized that Squall doesn't love her? Or is it because that Squall is purely insecure, he doesn't seem to express any feelings with a passion that he actually loves her, because he's shy or something? So in the future, Squall finally got out of insecurity, and told Rinoa about how he felt, etc etc and finally you know now :P ... meaning the past was affected by this!
