When the Green Knight called the knights' loyalty into question, Gawain saw Arthur's humiliation and felt compelled to defend him. Sheri Ann Strite explains that "Gawain is free to choose his next act, and through his choice he reveals with which set of values he is aligned" (p. 5), Gawain saw this as a chance to prove his morality to Arthur. Gawain's bravery and loyalty to Arthur are demonstrated by his acceptance of the challenge when no one else would. Furthermore, his devotion to Arthur exemplifies the code of chivalry.
