Merlin - The Tears of Uther Pendragon Part 1

In the season three opening, Morgana (Katie McGrath) is finally found after being 'lost' for a year.  The King (Anthony Head) is overjoyed at her return but Merlin (Colin Morgan) is worried she will remember that he poisoned her to save the kingdom.  She makes an effort to make up with him and to ask him for his forgiveness.  However, in truth, Morgana is working with her sister, Morgause (Emilia Fox) to drive Uther mad and leave the kingdom without a leader and ripe for conquest.  Merlin discovers Morgana's plan and follows her, only to be captured and magically chained and left for a whole swarm of giant scorpions to devour him.  He tried his magic to release him but it is no use.  He tried to fight off the scorpions but in the end cries out and the episode ends with him being rescued by the dragon, voiced by John Hurt.
This was a great return to a well made British television series.  This is made even better by watching it with my youngest daughter, who loves it.
