"quoth Gawain the good..."See in text(Fytte the Second)
“Gawain the good” is an epithet, a descriptive phrase that expresses a quality that is characteristic of the person being described; the epithet emphasizes Gawain’s virtues, for which he is well known. Just as he had done with the Green Knight, Gawain makes a covenant or agreement with the lord and will be honor-bound to keep it.
"His cheer changed full oft ere he saw that chapel...."See in text(Fytte the Second)
The passage indicates that while seeking the Green Knight’s chapel with no success, Gawain’s “cheer” or good spirits often changed, suggesting that he often felt discouraged or hopeless in his quest.
"Who ever knew any king to take such counsel as to suffer knights to be so tricked for a Christmas game...."See in text(Fytte the Second)
The passage is noteworthy in that it criticizes King Arthur’s judgment in allowing Gawain to accept the Green Knight’s challenge, very likely condemning Gawain to death. In most Arthurian tales, Arthur is depicted in only heroic terms, but in this narrative, he is portrayed as possessing human flaws in his character, among them pride and lack of wisdom.
