Arthur: (At the verge of tears) There are many things I have to thank you for. You have taught me so much. But most of all you have taught me... what it is to be a prince. I hope that this time, you'll be proud of me (Kisses his father's forehead and turns to leave).
Uther: (Grabbing Arthur's arm) Don't leave me.
Arthur: (Crying) I have to, Father.
(Arthur squeezes his father's hand reassuringly and leaves).
