When the ball is served it comes to Sue, she hits the ball twice, in succession, which is against the rules, she is on the same team as Carrie. This should have ended the game, but the point continues, the team they are both on gets the ball over the net, then it comes back, right at Carrie, she does not hit the ball, then the game is over, and a few of her teammates can be heard saying various insults about her inability to play the game and so forth. If they would have been playing by the rules, the ball should have never even came to Carrie.
