Right now, all I really care about is why Vaan tries to kill Balthier. I've observed that segment several times and they appear to be in soem crystal chamber (a large statue in the corner) and there's a big blob of pixels (I think it's supposed to be Fran! At least it looks kind alike her) is hunched over on the side of the screen. Vaan then slashes at Balthier, as he jumps over to guard/protect "Fran".

It's all so suspenseful!
