Merlin: I just wanted to make sure you had all you needed for your journey to Camlann, for the days ahead.
Arthur: Thank you... Merlin. Whadda you mean "my" journey?
Merlin: I'm afraid I won't be coming with you. Not this time. I'm sorry. I have an urgent errand to run for Gaius. Vital supplies that I can't obtain here.
Arthur: Vital supplies?
Merlin: Yes. It's not that I'm...
Arthur: No, no... It's fine. It's fine. I understand.
Arthur: You know, Merlin, all those jokes about you being a coward... I never really meant any of them. I always thought you were the bravest man I ever met. Guess I was wrong.
Arthur: Tonight... we do battle. Tonight, we end this war. We end a war as old as the land itself, a war against tyranny, and greed, and spite. Not all will greet the dawn. Some will live, some will die, but each and every one of you fights with honor and with pride, for not only do we fight for our lives, we fight for the future. The future of Camelot. The future of Albion. The future of the united kingdoms! For the love of Camelot!
Mordred: He was a loyal soldier. In robbing him of his magic, you've lost yourself a powerful ally.
Morgana: Perhaps, but now we know the war can be won, for Arthur is nothing without Emrys, and Emrys is nothing without magic.
Merlin: Arthur, I'm sorry I had to leave you. I didn't want to. I hope one day you'll understand why.
[Arthur is going to Camlann]
Merlin: I hoped never to hear that name again.
Gaius: He can not go, Merlin. You'll have to persuade him.
Merlin: I know Arthur better than I know myself. He'll not listen.
Gaius: If Arthur goes to Camlann, the prophecy will come true and he will die.
Merlin: This battle's the only way he knows how to save his people. If he's going to lose his life, he'll still go.
Gaius: Then what are we to do?
Merlin: If I can't prevent him from going, then I must protect him as best I can.
Gaius: But you can't protect him without your magic.
Merlin: Then I must regain my magic.
Gaius: I can't restore it. It's beyond my power.
Merlin: I know. Perhaps it's beyond anyone's power. No. If there's an answer, I must seek it elsewhere.
Gaius: But where?
Merlin: The birthplace of magic itself. The Crystal Cave.
Gwen: I'm coming with you.
Arthur: The battlefield's no place for a queen.
Gwen: I have no intention of joining you there, I can assure you. Arthur, if these are to be your last days, I would far rather spend them together than sit waiting for a man I might never see again.
Balinor: Merlin, you are more than a son of your father. You are son of the earth, the sea, the sky. Magic is the fabric of this world, and you were born of that magic. You are magic itself. You cannot lose what you are.
Merlin: But how do I find myself... again?
Balinor: Believe, Merlin. Believe what your heart knows to be true. That you have always been, and always will be.
