The Wicked Day

An Uncle, and an Enemy is the third episode of the fourth series of Merlin. The title of this episode possibly means that Arthur's uncle Agravaine will be introduced in this episode.

Probably Agravaine in this episode will have a key role at court, Uther is psychologically destroyed, and only Arthur and Merlin will try to save Camelot from a possible threat, and a possible alliance between Agravaine, Morgana and Morgause.

Sypnosis
Agravaine at first seems to have his nephew, Arthur's best interests at heart, but is in fact in league with his niece, Morgana.They also ally themselves with Nimueh who creates an unstoppable magical creature which Agravaine can turn into to distract Camelot while Morgana and Morgause attack secretly and as said last series not even the knights of Camelot can fight on both sides of the battle field at once.Can Merlin stop Morgana and Morgause and defeat and expose Agravaine as a traitor?
