Fleeing enemies, Merlin and Arthur take refuge in The Valley of the Fallen Kings. There, the sorcerer Taliesin cures the wounded Arthur and shows Merlin the Crystal Cave, which provides a disturbing vision of the future in which Morgana stabs a sleeping Uther. Come her birthday, Morgana, given a dagger by Arthur, steals into the king's room to kill, secretly followed by Merlin, who uses magic to thwart her. She is temporarily put into a coma, during which time Uther confides in Gaius that she is his natural daughter - a fact of which she is also aware. Gaius believes that Arthur should be told as now Morgana is a legitimate heir to throne and he stands in her way.

During the opening sequence of the episode, Arthur draws Merlin into the Valley of the Fallen Kings. In the following establishing shot, two statues guard the entrance to the valley. Both statues are copies of the statue of King Alfred the Great of Wessex in Wantage, depicting the king holding a scroll with an axe by his side. See more
