The episode starts with Prince Caillou coming out of school.
Prince Caillou: Mr. Dihn is a really nice teacher. He is better than ugly Ms. Martin.
Leo: Definitely.
Later on, Prince Caillou takes a walk around town. He then finds Mr. Ratburn.
Prince Caillou: Hi, Mr. Ratburn.
Mr. Ratburn: Your majesty, don't talk to me! I am still very crossed with the way you killed CourtneyFan6.
Principal Krupp: Me too! Don't talk to me either!
Prince Caillou: Wait. Please listen.
Principal Krupp: This better be important!
Prince Caillou: The truth is CourtneyFan6 was a devil. She is very bad and ugly, and she sold her soul just like my ex-parents and sister.
Mr. Ratburn: I see now.
Principal Krupp: Oh, that explains it.
Later at the castle
King John: You know, Prince Caillou, you can't always kill people that are your enemies. You have to learn how to love them too.
Prince Caillou: I know.
King John: Don't worry, I won't ground you. I'm just glad you learned your lesson.
Prince Caillou: Thank you.
