I'd like to know if there's any ways or means of keeping Whiney-dus in the first game. I've observed that if you score 2 goals in the second half of the first game that Whiney-dus does a little jig thing and gets immediately replaced by Wakka.

if I were to score some goals in the first half of the game, would Tidus not get replaced? say 2 in the first half and 2 in the second?
