The Ending - Some Questions (spoilers)

[FF_Lavindathar]

Ok, I just scraped through against Safer Sephiroth, with Barret and Tifa dead, Super Nova decimating Cloud, I went for the limit last attack rather than healing method, and Meteorain did about 80k damage, no idea why it did so much, as it has never done that much before, but I killed Safer.

So, some questions on the final demo....

Holy, comes to save the planet....it counteracts meteor, destroying it and also saving the planet.

Does holy destroy Midgar on purpose, removing all the mako-sucking technology, to "return the planet to its original state" kind of thing? Hence the jungle that has overgrown Midgar?

The lifestream, does that seep out of the planet to aid holy, because it isn't doing the job quite well enough, and its helping hand destroys meteor?

Is the little girl in Kalm Marlene, and why does she say "the flower girl"?

The very last image of Aeries, why is that there? Who sees her?

If Nanaki is the last of his kind, who is the mother to his two children?

Any idea what happens to the rest of the cast except Nanaki? Or is that just down to each's own interpratation?

Basically, could you please answer my questions, but also put a comprehensive interpretation of what you think the final demo means, and what exactly happens?

Thanx

Oh, and I've never seem Omnislash before, Cloud owned Sephiroth!!!
