There is a theory that Ultimecia is Rinoa from the future . The ending in the game is a little weird. Those flashbacks where Squall can't see her face make at least a bit of sense in this idea. The person who made the video I watched guesses that is the reason for the tear coming out of Squall's eye. Because he killed an older version of the woman he loves. I may be a little behind the times here, but this concept is new to me. What does everyone else think?

That's the first of that I've heard also Sab.. but from what I recall Ultimecia possessed Edea, and then proceeded to possess Rinoa, is that what you're referring to? Mind you, this could be extra info extracted from ULTIMANIA, much like Zanarkand being described as being placed above Mt. Gagazet in FFX...

Ultimecia is a sorceress from the future. Rinoa has sorceress potential, meaning she could become one in the future. This gives the theory a little merit. That bothers me a little. My sweet Rinoa a villain I just killed... kinda. The ending is so confusing with the flashbacks where Squall can't see her face. It would be a very interesting "Dark Empire" -like story. I guess I'm just too much of a old fashioned happy ending kinda guy to not have that bother me.

Here are some links to some refreshers:

Ending part one: This is the part that confuses me. Why can't he she her face in what we can guess is his memories?

Ending part two: Here is the part I like better. Rinoa finds him and her love seems to revive him and make everything better (yes, I'm a shmuck, I know). Then it goes on to the home video part that was very cool.

Ending part three: Here is the last part. More credits followed by a smooch.

And a couple of videos explaining the theory:

The second clip isn't quite as convincing. If you go back and watch the full version from the ending, there are shots of Edea and Seifer in there, too, and Rinoa's not becoming one of them. Oh well. Watch them and feel free to tell me what you think.
