Return of the Giant - S4.E13

Robin attends a party at Glister Hall to celebrate the first anniversary of Ariel's accession to the title of Lady Glister. Lord Teague, a neighboring noble, whose proposal of marriage has been spurned by her, steals her father's notebooks, and uses them to conjure up the twin of the giant that Robin defeated before, to help him. The giant has to kill Ariel to stay alive. Robin battles the giant, with the help of Kevin, a local lad who wants to impress a girl, Olivia.
