Uther: Where have you been?
Merlin: I have walked my way since the beginning of time. Sometimes I give, sometimes I take, it is mine to know which and when!
Uther: You must help me, Merlin!
Merlin: Must I?
Uther: I am your King!
Merlin: So! You need me again now that my truce is wrecked! Years to build and moments to ruin! And all for lust!
Uther: For Igrayne! One night with her. You don't understand, you're not a man. Use the magic. Do it!
Merlin: [considering] Igrayne... You will swear by your true Kingship... to grant me what I wish, then you shall have it.
Uther: [kneeling] By Excalibur, I swear it!
Merlin: What issues from your lust, shall be mine. Swear it again!
Uther: I SWEAR IT!
