In the scene right after David and Nicole slept together you see hear Nicole start to tell Gary about it, as they are walking out of school, look closely and you can see that Nicole is wearing a dress and a coat and her hair is down and Gary is wearing a pullover. When it goes to a close up shot of them(right before they hug) Nicole has her hair up in a pony-tail and is wearing jeans, a tee shirt , and a coat and Gary is wearing a plaid shirt! They are wearing completely different outfits! The scene when they are walking out of school, is used again later in the movie right before Gary dies.
