My only friend, the end (spoilers)

[.:kerrod:.]

i just finished this game for the first time (i know, bit slow off the mark ) and i must say i am a tad confused...

i was semi-satisfied with the ending, but i have a few questions:
1. What happened to Kuja and how did Zidane actually escape? (i'm guessing the answers to this will be 'he died' and 'we never find out')
2. Eiko...mother and father? presumptuous much? what if those two don't want a bratty little kid who is very capable of killing them both when she doesn't get her own way? (this wasn't really one of my questions...it was just a bit weird)
3. Wtf is with those Vivi things?! "Vivi is our father"?!
4. Where did Vivi come from? Was he created like he always suspected?
5. What was the significance of the necklace that Garnet dropped (i realize the symbolism in the fact that she chose Zidane over this, which is clearly very important to her, but i forget what it actually is, could you remind me?)?

and just a side-comment, even though i knew the cloaked man (in the play) was Zidane all along, i got goosebumps when he whipped off his disguise...i have no idea why, but i feel like a loser it's a very nerdy thing to experience, especially seeing as i wasn't as emotionally attached to this game as the other final fantasies

one of the things i didn't like about the story was all the people who looked like Zidane...especially seeing as there were girls who looked exactly like him, but still looked very womanly (meaning Zidane looks kinda like a chick ). in saying this, however, i would like to acknowledge the fact that Kuja also looks kind of like a girl, but he is captivating...especially in Dissidia form, he looks smurfing awesome

i'm sure there are more things i need to say, but this is all i can think of for now
