The Challenge

S1, E8: Fed up with the disruptive rivalry between the Musketeers and the Red Guards, the King calls a contest between them to settle which one is stronger once and for all. D’Artagnan is determined to be chosen to fight so that he can prove himself worthy to be a Musketeer. But first he has to learn to control his impetuous nature and to fight with his head, not his heart.
