Plus the game had that whole "Book Ending" thing with the "I want to be your Canary" play, in regards to the play I was really disappointed with how it was executed, I honestly thought the play was going to serve as forshadowing for the intire game (like how in VIII, the song sung at the beginning forshadowed the events of the game), such as that scene in where Marcus Inadvertently stabs Cornelia, I thought that would really happen later with Zidane and Garnet, but the only thing from the play that even remotely connects with the anything is the whole Zidane/Garnet thing (very loosely I might add as Marcus and Cornelia showed way more chemistry for each other than Zidane and Garnet did.)
Then there's the beginning of Disk 3 with the melodrama of Garnet being coronated and Zidane being all drunk in a bar, okay that makes no sense, why are they focusing on coronating Garnet immediately, did everyone forget that Kuja is still on the loose, why are they wasting time on this coronation and celebration when there is a threat to Garnet, just wait until after the madman responsible for all these atrocities is stopped to have your coronation, and then there's Zidane and others dumb move to LEAVE Alexandria and head to Treno to play a CARD GAME, everyone's forgotten about Kuja apparently, this whole thing grinds the story to a halt.
Then there's Kuja's (predictable) attack on Alexandria and Garnet's speech: "No... I can't depend on them anymore!" "As the queen of Alexandria, I must protect my kingdom." I hate this line of dialogue so much, it messes up the love story again, it sounds like Garnet never truly loved Zidane and was rejecting him and all that above mentioned melodrama was completety pointless, there is nothing wrong with relying on someone especially the one you love, as long as it's not over reliance and they can depend on you, but this was never Garnet's problem, her problem was the exact opposite of what she said.
She was under reliant and self centred as shown with her idiotic return to Alexandria plot line, a better line would be "I will protect Zidane and etc. etc. but I digress because as stated above and with Beatrix, this part of the story shouldn't have gone this way, and to add insult to injury, after Zidane rescues Garnet and Eiko from the collapsing tower, instead of reconciling the relationship, the Invincible decimates Alexandria and we go right back to the bajillionth wangsting moment for Garnet, and Zidane completely ignores all this and goes right back to being cheerful for no reason, making that whole plot line even more pointless.
This just sums up my point that Garnet has WAY too much angst and Zidane has too little, Zidane should be the one angsting, he couldn't protect Garnet, and what the game should have done was put him in a coma after the Alexandria attack with Garnet being by his side the whole time and not have that annoying mute thing going on (the damage to Alexandria wasn't even that severe, when you go back most of the residents are there okay, and there are petitions to help fundraise for faster repairs), and Zidane wouldn't wake up until the other characters were captured at the desert palace, giving more focus to the other characters.
