A knight’s best friend is fighting and doing very well at a tournament. Near the end of the day, the knight’s liege lord orders him to go and fight his best friend, who is now exhausted from battle. The knight doesn’t want to do it, but he’s sworn to obey his liege, so he jousts against his friend and knocks him off his horse. He then refuses to fight his best friend on foot. His friend is humiliated and hates him now.
