The Question and Answer section for Sir Gawain and the Green Knight is a great resource to ask questions, find answers, and discuss the novel.
My line numbers do not match yours. Can you quote where the section begins so I know where you are? thanks.
I'm not sure what point you are referring to. The Green Knight tests Sir Gawain’s honesty and chivalry.
The Green Knight challenges Arthur and his knights to step forward and strike him, using his own axe. His condition.... whoever took the challenge must meet him a year later and receive a returning strike.
