Don’t read if you haven’t seen the episode

Arthur and his Knights stumbles upon a wreckage of supply cart bound to Camelot. Arthur assumed that it was the work of Saxons. Mordred sees a cloaked figure leaving the scene. Mordred was able to catch the person and it was revealed that it was Kara, Mordred’s friend and love interest. He ordered her to escape but Merlin saw him doing so. Mordred told Arthur and the others that it was just a deer.

Mordred then sneaks into Gauis and Merlin’s house and stole some healing potions. Later in the night, Mordred went back to the woods and found Kara. Using he potions that he stole, he healed her. Merlin caught Mordred sneaking back into the castle. When he confronted him, he confessed that he knew Kara since they were young and that she is a druid. He made Merlin promise not to tell Arthur.

The next day, Arthur and Merlin found the trail left by Mordred. Eventually they found Kara. When Arthur’s guard was down, Kara attempted to kill him but Merlin used his magic to foil Kara’s plan. She was then taken to Camelot to stand trial. Kara confessed in killing the people in the Camelot Patrol. Bound by Camelot’s law, Arthur had no choice but to sentence her to death. Mordred confronted Merlin and told him that he has gone too far and he will pay for his acts.

Mordred pleaded for Kara’s life but Arthur had refuses to rescind his decision. During their conversation Mordred realize that Merlin did not betray him. Knowing Modred, Merlin followed him to talk him out of it. Mordred refused to let her die and told Merlin that he knows that he never betrayed him but warned not to betray him then.

Mordred freed Kara and was about to escape Camelot. Arthur and the knights cornered them eventually. Mordred pleaded with Arthur and promised him that they will never come back to Camelot if they promise to let them go. Arthur refuses bound by his duties to Camelot. With sword drawn, Mordred was prepared to fight his friends for Kara’s sake. Kara told him to used magic to kill them. When he was just about to use magic, Percival knocked him out.

Back in Camelot, Arthur was having difficulty in making a decision on what to do with Mordred. He gave Kara a final chance to repent but she refuses and told Arthur that he deserves what is about to happen to Camelot. Kara was put to death by hanging.

Mordred was angered and escaped using a powerful magic that blew his cell doors apart. He then went to search for Morgana and offered a truce. And in return he offers information on the sorcerer that she is seeking for, Emrys. He told him that he is in Camelot and all along she is looking for Merlin.

In the preview of the next episode, Morgana and Mordred prepare to wage war on Camelot. Merlin is captured and is unable to use his Magic. The Battle of Camlann has started. With two episodes left in the series, it seems that Merlin will reveal his Magic on the last episode. I hope the years of waiting for Merlin to reveal his magic would be all worth it. I just wish that they don’t just cram it in one episode only.

The Diamond of the Day part 1 is scheduled to air on Dec 22, 2012 and the series finale two days after just a day before Christmas
