Find out what happens in the season finale of BBC One’s fantasy drama series, Merlin.
Episode Thirteen: BBC One, Saturday 13th December. 7.10pm.
Whilst out on a hunting trip, Arthur and his men encounter a huge and terrifying monster that has the body of a lion and the head of a serpent, with a huge pair of dripping fangs. Gaius explains that what they encountered was a questing beast, said to have been conjured from the nightmares of a long-dead king. It is a creature of great power from the old religion, whose bite is always fatal. Uther refuses to acknowledge such folly and sends the knights out to kill it. Arthur and his men, meanwhile, creep through the forest to find the tracks of the beast and nervously follow its trail to a cave. As they cautiously enter its lair, the beast jumps out of the darkness at Arthur. Merlin has some tough decisions to make that could see his world changed for ever.
Bradley James plays Arthur, Colin Morgan plays Merlin, Richard Wilson plays Gaius and Anthony Head plays Uther. Tonight’s concluding episode also stars Michelle Ryan as Nimueh and John Hurt as the voice of the Great Dragon.
