Awesome / The Green Knight

• Upon accepting the Green Knight's challenge, Gawain asks if one of the present knights will lend him a sword. When no one steps forward, Arthur unsheathes Excalibur and gives it to his nephew. No words are spoken in the passing of the king's sword, but the gravity of the moment is palpable.
• While a slightly perverse one, Gawain choosing death over leading England into destruction, especially in light of the Character Development he has to go through to even reach that point. Moreso, if it leads to him being spared by the Knight and becoming The Good King, as vaguely implied by the post-credits sequence.
