03E04 - Gwaine

A young mystery man, Gwaine, helps Merlin and Arthur when outnumbered in a tavern fight, in which he is injured. They take him to recover at Camelot where he expresses his dislike of the aristocracy (Arthur excepted, eventually) since his father, a knight, and his family were abandoned upon his death by their king. Using magic, the villains ousted in the brawl assume the identities of two knights and arrive in Camelot to take part in a joust where they aim to kill Arthur, using trickery. Gwaine and Merlin realise this but Gwaine is banished by Uther for attacking one of them. Merlin is hard-pressed using his magic powers to save Arthur in the joust and it is Gwaine who rescues the young prince for a second time. A grateful Arthur looks forward to the day when Gwaine will be dubbed a knight.
