Such as Ellone clearly knowing both Squall and Quistis yet neither reconized her.By MJN SEIFER: The fact that people dismiss the orphanage scene as "Deus Ex Machina"(sp?) purley because they didn't notice a ton of subtle clues leading up to it.
Irvine's comment to Selphie "We're destinied to be" on the train to Deling. Makes sense if you consider the fact that they somehow ended back together as adults.
Zell and Irvine not getting along too well. While playing once, I was in Balamb and I got that little event where Bad Rascal pushes the girl in front of the hotel. After I went into the hotel and back I talked to the guy and, with both Zell and Irvine in my team, got interesting dialogue hinting that Irvine had bullied Zell when they were kids
That's all I can think of right now for that.
Another dumb thing, is the simple lack of character development for everyone save Squall and Rinoa. I mean sure, they're the main central characters, but they completely ignored the others.
