Merlin - Season 2 (2009)

Gwen is mistaken for Morgana and kidnapped. Against Uther's wishes, Arthur heads out to fight for her freedom, with Merlin by his side to help him.

Part One: An ugly old troll drinks a potion transforming herself into the glamorous Lady Catrina, who arrives at Camelot with her servant Jonas. Gaius, who has met the real Catrina, and Merlin, who witnesses her true identity, are unable to convince bone-headed Uther of Catrina's real nature, especially when she bewitches him by giving him a magic pendant. Merlin attempts magic to expose her but she is too strong and it is too late to stop her marrying the king and becoming the queen of Camelot.

Merlin spies on the troll and steals the potion she uses to resemble Catrina, replacing it with a fake one made by Gaius. Consequently she turns back into a troll, in view of everybody, but Uther, still bewitched by her, fails to see this. Merlin learns that the only way to break the spell on him is to make him weep real tears. Thus Gaius prepares another potion, which Arthur drinks, and makes him appear to be dead. This does the trick and the king finally comes to his senses. Arthur kills the troll and Jonas and thanks Merlin for his efforts.

In his determination to rule magic out of Camelot forever, Uther hires the services of Aredian, a terrifying witch hunter who is most feared due to the fact that he stops at nothing in the quest to uncover all and every kind of sorcery. Even though no one is under direct suspicion, several people in Camelot are afraid that the witch hunter could see straight through them: Morgana is worried that Uther might have her executed and Gaius is concerned for the fate of Merlin and his own, since caring for the young warlock is considered crime and treason. Will all three be ...

When a mysterious warrior challenges Arthur to a duel, no one could possibly predict the devastating chain of events it sets in motion - least of all the young prince himself. Arthur and Merlin soon find themselves on a strange quest at the behest of the beautiful Morgause. Through her, Arthur discovers a dark secret which threatens to bring about the downfall of the kingdom.

Merlin saves a Druid girl from a bounty hunter's cage, but there is more to her than meets the eye.

Rulers from the Five Kingdoms converge on Camelot for a peace conference, including King Olaf and his spoilt, over-protected daughter Vivian. King Alined is also present, along with his jester, the wizard Trickler. He is a disruptive force who wants to cause discord between Olaf and Uther to gain ultimate power for himself. To this end he gets Trickler to bewitch Vivian and Arthur so that they fall in love and incur the annoyance of Olaf, who will challenge Arthur to a duel. This time it is down to Guinevere, rather than Merlin, to break the spell.

Mordred brings a warlock, Alvarr, to see Morgana, and they persuade her to steal a crystal with magical properties from the vaults of Camelot. Alvarr tells her it can be used to help people like themselves with special powers, though he really intends to destroy Camelot with it. Merlin and Arthur pursue him, returning him and the crystal to court. Mordred escapes, and Morgana (having disowned Uther), springs Alvarr from prison by drugging the guards. Merlin, having looked into the crystal, is alarmed by a vision of chaos, but Gaius assures him that it is far into the ...

Using an incantation, Morgause revives the deadly Knights of Medhir and, whilst Merlin and Arthur are the sole survivors of the party sent to beat the knights, Morgause uses Morgana to bewitch Camelot so that everybody except Morgana herself falls asleep, rendering the court defenseless when the knights approach, intent on killing the king. Merlin learns from the Great Dragon that the only way to break the spell is to kill Morgana, so he uses her as his bargaining power to force Morgause to call off the attack. As a consequence he must honour his pledge to free the ...

Morgana has gone with Morgause, and the dragon, freed by Merlin, repeatedly attacks Camelot, causing huge fire damage. Only a dragon-lord is capable of containing the beast, men whom Uther persecuted years earlier, from which only one still survives (Balinor), who lives like a hermit in a cave. Gaius, who helped him escape Camelot, tells Merlin this is his father, and when Merlin and Arthur trace him, Merlin reveals himself to Balinor (though they keep it from Arthur). Balinor agrees to come to Camelot to assist, but there is further drama before Merlin proves himself...
