I love Arthur in all of them. But in this he shows how much he is willing to learn. The Lancelot and Guinevere episode had some amazing Arthur scenes. But it also broke my heart.

it's my all time favorite episode and one of the reasons why is Arthur because you can see him changing and see the great king he wil become, and lie m you said Melly, he's wiling to learn and does it with the help of Gwen , showing his kind and kingly side. and I don't know if it's just me or does he behave less like a "spoiled prince" or prat-ish since this episode?
In "The sins of the Father" he was very good too.

Well, the people have spoken.
