merlin 12: To Kill the King torrent

Original Air Date—6 December 2008
Gwen's blacksmith father Tom is approached by Tauren, who possesses the alchemist's stone and wants Tom's help in turning metal into gold - gold he intends using to overthrow the king. The palace guards raid the smithy and Tauren escapes but Tom is caught, sentenced to death for assisting sorcery and ultimately killed trying to flee from prison, having been helped by Morgana. She is appalled by Uther's callousness and tells Tauren that she will help him in his plot, unaware that Merlin is listening. On the pretext of visiting the grave of her father, for whose death she blames Uther, she rides out with the king to lead him into Tauren's trap.
