User blog comment:Broman178/How Arthur could have confronted Agravaine in the Series 4 finale./@comment-4190137-20120310041843/@comment-4650675-20120310082112

The only drawback with Gwaine-looks-like-Cenred's theory is that Agravaine would never betray Morgana, at least that's how he looked like. It could later be revealed that he was lying in order to stab him in the back though. Also, to Broman178's theory I would also add Morgana in the dialogue, explaining how Uther always lied to her and what a cruel man he was, making Arthur break down.
