How 'bout this?

How about we discuss these varied interpretations. Instead of stating someone is infailiably wrong... We can try to see from each other's perspective...

Now, the Squall dies and is revived by Rinoa version seems a likely occurance.

Why? Well, with 'Love' there is often 'Tragedy' involved in a 'Love Story'... which I really did not feel in this story, but, I digress.

In a Time Compressed World, a decaying one at that, no one can exist.

I won't go into the hallucinations/memories/Ultimecia's Message 'theories' for now, but at any rate... It seems that Squall IS in the Flower Field as he promised but is not in time-sync with Rinoa...

As the Time Compressed World decays, he dies, and Rinoa, as it seems to be demonstrated often, unconciously uses her Sorceress Power to 'find' Squall right behind her in the TC version of the flower field.

Now seeing that Ultimecia could use Edea to bring stone statues to 'life' and various other phenomena, it does not seem too far fetched that she would be able to simutaneously bring herself and Squall OUT of the Decaying Time Compressed World (Flower Field) and bring Squall back to life.

It may even be that Squall, trapped in the Decaying Time Compression, had 'ceased to exist' and by Rinoa bringing him 'back' he... 'existed'.

I guess that would give some merit to Laguna's 'speech' of love and friendship to bind you back to the world you came from...

Yeah... I like that...
