In this short scene, the brats discuss whether or not they believe Cal's claim that he didn't participate in the prank. Cal is upset that they don't believe him, but he's not angry just because he doesn't want them to believe him. He's angry because he thinks that if they believed him, he wouldn't have done such a dishonorable thing. He also thinks that they're twins, or just people like them who look alike. Cal thinks that he might not have been able to sleepwalk through the prank, because he was tired of playing the subway games and falling asleep.
