hahahahaha agreed. the only real reason yuna is so important is cause she is the only one who can summon aeons. if any of the others were able to, i dont think many people would be using her... if they dont already... like me
there are so many video clips that we could bag out, but unfortunatly all of them are necessary to the story line. some may seem rather crap and unimportant, but they all have a purpose. especially the clip in question. it may seem rather retardo, and makes us want to stab tidus even more, but its necessary for the character development and traits between tidus and yuna. the two "main" characters of X.
