2x37 - The Legend of Prince Valiant

Lord Maldon and his follower Allen have stepped up their efforts to generate civil unrest between foreigners and native Camelotians. One of their schemes forces Valiant to return to Camelot for the sake of an injured loved one. Once home, he learns that King Arthur intends on taking advantage of the upcoming Sword and the Stone Celebration to set in motion a plan to help combat Mordred's forces. What shocks the prince, the queen, and the other Knights of the Round Table about this plan is that their king must die for it to succeed.
