I was disappointed that Mordred's turned so easily. He saw that girl killing people in cold blood, he heard her fanatic speeches and he still thought she's innocent?
He is naive but not to that degree.
What else could Arthur have done? He gave her a chance no one had before, but she blamed him in what? In his father's sins? Like there was no examples of magic using for bad?
I was hoping till the end that Mordred saw through that girl's actions and saw who's there to blame and escaped to kill Morgana cause she was responsible for the girl's death not Arthur. But it looks like all my hopes went poof and he chose the easiest way to blame others such as to reveal Merlin's identity to his sworn enemy knoing that Merlin didn't betray him.
It kind of make Mordred less complex and interesting character to me :/ He became more and more like sam in spn blaming others and choosing the wrong women.
