Arthur, Merlin and the knights are on their way through the Valley of the Fallen Kings, having picked that route for its secrecy. Unfortunately it’s not that secret, as a band of mercenaries come hurtling down from the slopes either side of them. The knights begin to fight and Arthur is dragged off his horse, though he manages to overcome his attacker. Merlin uses magic to throw a horse-backed mercenary to the ground, but while distracted he is wounded by another warrior and falls to the ground. She chants a sleep that renders Merlin unconscious.
