Gaius: I can see deep into your heart. And it is cold, cold as stone. You play Uther’s loving ward, you play it so well. You fool him but you don’t fool me. You would see Uther dead. And Camelot destroyed.
Morgana: Why would you say such a thing?
Gaius: Because it is true. There is evil in your heart.
Morgana: I don’t know what’s come over you. You were always such a good friend to me.
Gaius: I see the truth frightens you.
Morgana: It’s you that frightens me.
