Quistis is here, which means the Trepies are also here. When you think about it, it's astonishing that Cid wasn't murdered by Trepies the moment he dismissed Quistis from her position as an instructor.
Wait, is Quistis an instructor right now? When is this version of Balamb Garden set? It's very unclear. Irvine and Rinoa are here, but so is Seifer. The continuity is a mess, frankly.
Speaking of when Quistis was an instructor, this is where you can find my thoughts on Squall and Quistis's relationship at the start of the game. As a heads-up, I like Quistis, but I'm a little critical of her in these thoughts. It's possible Cid isn't the only one at risk of being murdered by Trepies.
Alternatively, stick around for a quick lesson on the animation of Final Fantasy VIII.
If you don't feel like paying attention in class, of course, you could just fire up your computer and go to Garden Square.
