- Queen Mab: [to the Mountain King] Why give him the sword? He won't be able to do good with it!
- King Arthur Pendragon: I don't know what I'll do, or who I'll become, only who I am!
- Mountain King: A wise answer.
- King Arthur Pendragon: [looks at Merlin] I had a wise teacher.
- Queen Mab: [to the Mountain King] You're destroying the old ways! You'll be forgotten, just like all the rest of us!
- Mountain King: That is your fear, not mine, Mab. I can not die! I am the Rock of Ages. I live for ever, on the edge of dreams...
- King Arthur Pendragon: I made a mistake that night with Morgan. But I can't believe that I'll be condemned for all eternity for one mistake.
- Merlin: No, not by me. I'll never condemn you, Arthur.
- Merlin: Will you be able to handle Mordred?
- King Arthur Pendragon: It's just one more battle. And right is on our side.
- King Arthur Pendragon: It's time to end it all.
- Mordred: Well... we agree on that at least. You know father, if you'd lived, I don't think we'd have been very happy as a family.
- Merlin: I had won. I was trying to smile but it was the smile of desolution. Inside, I felt only the pity and the terror and the waste of it all. Everyone I had ever loved, and who ever loved me - all gone... all gone down...
- [Lancelot saves Guinevere, and they escape]
- Merlin: Lancelot always saved everything to the last moment. But then, my memory of Lancelot is that he never got anything right.
- [Lancelot's wife learns of his affair with Guinevere and commits suicide]
- Merlin: [after yelling at Lancelot] I judged Lancelot too harshly. The blame was on me, too. After all, I had chosen Lancelot.
- Frik: I've always believed it was better to be a coward for a lifetime than to be dead in a day. And yet, here I am fighting. Fighting on the side of right, which is worse.
- Merlin: You lied to me!
- Lady of the Lake: I didn't lie, Merlin. I said the guardian of Camelot would be at Astolat.
- Merlin: That's where I found Lancelot!... It wasn't Lancelot, was it?
- Lady of the Lake: It was the boy, Galahad. It's human to make mistakes, Merlin, and part of you is human... the best part.
- Merlin: I was Arthur's tutor. I didn't teach him magic. I taught him ethics and morals. It is much more difficult, believe me.
- Merlin: I couldn't stay away for long. Arthur was more to me than just a king. And I was curious to see what was going on.
- Mordred: I'm sorry, father, but I'm going to destroy you. And this time, your pet wizard won't save you.
- King Arthur Pendragon: [about Guinevere and Lancelot] Merlin, what should I do?
- Merlin: In the end, you must uphold the law.
- Mordred: I'll tell you.
- King Arthur Pendragon: Who the devil are you?
- Mordred: Eloquently put, "Who the devil?". Yes indeed. Who the devil?
- Mordred: [on his dead mother] She sleeps alone at last. One day she was laughing, smiling, the next, gone like a summer breeze in the midst of life, etc, etc, etc, and so on and so forth.
- King Arthur Pendragon: Guinevere how could you do it? Did you not think of me at all?
- Queen Guinevere: You left me alone for years, did you not think of me? What of my honor finding out my husband had a child by a woman called Morgan Le Fay?
- Mordred: Good one. Oh, come, Father, this is becoming distressingly personal.
