Merlin - Season 2 - Eps 5: Beauty and the Beast (1)
Lady Catrina and her strange servant Jonas arrive in Camelot, where they are welcome to stay by a most delighted king Uther, who becomes captivated by his latest guest. Arthur, on the contrary, far from sharing his father's enthusiasm and in the sight of the flirting going on, is pretty appalled with the situation. Merlin and Gaius have the feeling that she is not what she seems and their suspicions are proven true when Merlin discovers that Lady Catrina is a troll and that unfortunately, her intentions are far beyond the prize of a king's heart. Horrified, he reveals the truth to Arthur, who doesn't believe him. Merlin embarks in the task of proving the real nature of the woman while at the same time saving Uther from ruin and Camelot from fall. Will the young warlock be able to overcome the powerful magic of the troll before it's too late?
