So... Ultimecia?

I mean, come on.
>Can I tell you a story? I had a dream. It was a scary dream. We make a promise. We promise to see shooting stars together. I get dressed up and put on your ring. But the thing is, I can't remember where I'm supposed to meet you. I start to panic. I really want to see you, Squall, but I don't know where to go. I start running through the mountains, the desert, the plains... Through Timber, Balamb, and Galbadia... When I realize I can't run any longer... I... I just want to see you so badly... So I scream, Squall, where are you!? Then I woke up. I was crying.

That text right there tells us several things:

Rinoa is lost in a place where time has no meaning.
Rinoa might have been there for a moment or even eternity
Rinoa can't remember her own past or what she is waiting for
Rinoa only knows she is waiting for someone and that is their meeting spot

In the game she even as a foreboding nightmare about it.
