'The Die is Cast' means metaphorically the die has been rolled, in reality, the action has been stood and you cannot take it back. I think this is a high relation to Series 5 in different ways such as; Morgana has made it clear that she's against Arthur and the rest of Camelot, Mordred has made his move, possibly the fact he's going to murder Arthur in war and really the whole series relevates to this tagline.

Good blog post.
