Valiant tries to adjust to being Camelot's new leader as Mordred's army advances on them, not helped by the fact that too many people are overwhelmed by Arthur's death and can't bring themselves to fight without his guidance. Morgana helps Mordred further by creating a potion that, when making contact with the skin, will poison its victim. She sends Kay to kill Gawain and Bryant with it. When Valiant sees the body of a guard who grew suspicious of Kay's incomplete disguise he realizes who the traitor is and what he plans to do. While Arn remains behind, he and Rowanne take off to keep Camelot's most experienced soldiers alive when they're needed most.
