Merlin: (About Camlann) I hoped never to hear that name again.
Gaius: He cannot go, Merlin. You will have to persuade him...
Merlin: I know Arthur better than I know myself. He will not listen.
Gaius: If Arthur goes to Camlann, the prophecy will come true and he will die.
Mordred: This battle is the only way he knows how to save his people. If he's going to lose his life, he will still go.
