Laughing, the Green Knight explains to Gawain that he is actually the same lord of the castle where Gawain spent his holidays. The first two blows, he claims, were in return for the way Gawain returned the kisses of his wife, following the rules of their game as an honest man should. The third blow, he says, was for Gawain’s failure to return the green girdle to him on the last day. But because Gawain’s failing was only because he wanted to save his life, and not because he's just dishonorable, the Green Knight forgives him. He leaves Gawain with only with a scar and a girdle as a reminder of his very human sin.
