There may already be a thread about this but does anyone know why the screen goes crazy before the fight with Yunalesca. I mean very little happens to her during this time and i can't see any reason to make the screen do that.

Maybe a scratch or some dirt on the disc?

I know what he means... It's nothing to worry about, its normal..

Maybe there's something wrong with the television.

Its when wakka and Lulu are having a conversation with Lulu starting it saying
"You could always run"
