Hmm but if you see the game storyline Quistis visits the garden doesn't actually say she taught there see the thing is you can only become a SeeD at Balamb or Gabaldia Garden you can't from Trabia as the only people living nearby is the Shuumi and theyre peaceful people so it's a little far fetched for me the ones I prefer are those that try to provide character development inside the actual storyline of the game unfortunately cannot find any of the ones I've read that were any good
