The Duke's son, Charles, slaps his nose with a young lady, and the Duke is furious. He wants to apologize to the young man, but Charles refuses, saying that they can't offend the duke's general mansion, and that they don't have the money to do so. The Duke calls for the professor, who arrives and tells Charles that the arrows on the tree have poison on them. He tells Charles to go back to the General and tell him what happened, and then he'll come visit him later on. He also suggests that the Duke reward the professor with gold coins, which he can exchange for various skills.
