Revealing mistake: When Troy crouches down on the rocks, and leans down to see his reflection in the water, oddly the reflection is not reversed, yet his hair is combed the opposite way. (Did the director actually think that if Troy's hair was combed the opposite way it would pass as a reversed reflection?) Additionally, when he crouches down, the bottom button on Troy's shirt is unbuttoned, but in the reflection (as well as in the previous and following shots) the bottom button is buttoned up.
Revealing mistake: After Ryan is given the Star Trophy at the talent show, the classmates gather outside holding lanterns. The line pulling Troy's lantern up is visible, just as the first blue fireworks starburst explodes above it. (01:44:10)
Answer: Although the dialogue makes it hard to follow, the game was actually a challenge between Ryan/Gabriella and Chad. If Ryan's team won, Chad and the guys would have to perform in the talent show; if Chad's team won, Gabriella and Ryan would have to forget the whole thing. Ultimately Ryan won the respect of the guys even though his team lost the game hence Chad asking what would he have to do in the show.
