So, what you're saying Crystal is:

That quote, which makes the entire plot irrelevant, is what we base her power on?

Something she herself never hinted at wanting or caring about is what she was doing?

And you're arguing the last fight was actually in space? lol That's the weakest one yet.

And no one cares about you making excuses. We care about -evidence.- What did you say earlier? WHat SE thinks > what I think? And yet you go right ahead and argue your position, not supported anywhere in the game or canon, that "Plot Protection" allowed them to survive. I'll just remind you this is YOUR idea alone and is supported by nothing.

I'm also starting to think you're full of it. I remember scanning Ultimecia's final form and all it said was something like this is the form she took on for Time Compression.
