The Eyeball is Jeff. He is a giant floating Eye that flies about the skies looking for his partner Claire. Will he ever find them? Will they be reunited with Montgomery the nose? KEEP PLAYIN' TO FIND OUT!
Also also I hated the love story in VIII because it ruined Squall. He was this asshole in a world full of idiots and I took great pleasure in him not giving the slightest of smurfs about all of the stupidity around him. He just was not having any of it. Then he became all sappy and talkin' 'boot FEELINS and it ruined him
Also also also Quina does not serve any purpose. It is a joke character designed to provide a little bit of levity to situations. I think FFIX's story focuses on the first four (plus Eiko) a bit too much and Freya, Amarant and Quina are mostly there to make up the numbers.
