Season 2 Episode 6

The Sheriff's Black Knights gather at the castle to attend a feast and declare their allegiance to Prince John. With the Outlaws disguised as entertainers, Robin infiltrates the castle to join forces with the only man who can stop them, the Sheriff of Winchester. Winchester's territory is crucial to the Sheriff's "Shah Mat" plan which will apprehend a homecoming King Richard at the southern ports. When Robin is satisfied that he has convinced Winchester to stand up to the Sheriff, he sends the Outlaws on a diversionary mission and writes a farewell letter to Marian. Preparing to make his greatest sacrifice alone, Robin hopes to put an end to "Shah Mat" by killing all the Black Knights. As Robin enters the feast disguised as a Black Knight, he discovers that Winchester has double-crossed him, with Marian added as a sweetener to his deal. Surrounded by a roomful of enemies, Robin faces certain death alone.
