2x14 - The Adventures of Robin Hood

Sir Simon, and agent of Prince John, goes undercover as a cobbler named Jack. He pretends to be mistreated by the Sheriff, in a plan to join Robin's band, and to turn the outlaws against Robin. 'Jack' lays black rumours of Robin robbing clerics and taking money from the King's ransom and betraying Tom of Guant, now residing in the Sheriff's dungeon.
