剧情引导：合唱团因为Sue和Will的合作领导被折腾得七零八落，这俩人恨不得把对方给掐死，最后连各个团员都受不了了，纷纷离去。Sue和Will冷静下来反省......

Sue: I know my methods are extreme. And I know I'm not like the rest of you hippies, caring about the kids' feelings as if they're real,but I do care about teaching. And when I coach them,and they win... I win. And you know how I feel about winning.
Will: I do. Look,who's to say everything I do is 100% on the ball?
Sue: No one would say that.
Will: Probably right. But,um,in hindsight... you were right to shine the spotlight on the fact that those kids are minorities.
