Gawain remains at the castle while the host and his men go hunting. While he is still half asleep, he hears the hosts wife come in his room and sit next to him on the bed. She starts to joke with him and lavish him with admiration and he is gracious of this. She gets ready to leave and accuses him of not being the real Gawain because the real Gawain would kiss her before she leaves. He is a hero here because he is chivilrous. He listens to the lady, and does control himself around her even though she is trying to seduce him.
"Such a great man as Gawain is granted to be,/ This very vessel of fine virtue and fine courtesy,/Could scarcely could have stayed such a sojourn with a lady/ Without craving a kiss of courtesy" (70.)
The host returns home and gives Gawain the deer he killed that day. Gawain thanks him and in return " [kisses] him in the comeliest way he could think of." (73) He is a hero here again because of his chivalry. He gives the king a kiss because his wife gave him a kiss.
The host gives Gawain the fox that he had hunted that day. In return, Gawain "[clasps] the castellan and [kisses] him thrice." (93) He is a hero here because he gives the host three kisses, and this is chivalry. There is a moment where he is not a hero here though. He does not tel the host about the green girdle which was given to him by the hosts wife. Even though this happens, he is still a hero. He is a human and all humans make mistakes.
On the second day, the lady teasingly talks to Gawain, and forces him to kiss her two more times. She also arguments for how his acceptance of her love would be chivalrous. He is a hero here because he is letting her do this because and is respecting her which is one of the main pillars of chivalry.
"Since the choicest thing in Chivalry, the chief thing praised. / Is the loyal sport of love" (78.)
That night. the host brings the head of the boar ( on a stick) that he hunted that day and gave it to Gawain. In return, Gawain " clasped the castellan's neck and kissed him kindly/ And then served him a second time in the same style." (82) He is a hero here because of his chivalry. he gives the king two kisses because the hosts wife gave him two kisses.
Gawain is woken up from nightmares about the Green Knight by the lady again. They have another conversation, and during the course of this conversation they exchange three kisses. The lady offers him a ring, which he refuses. She then offers him her green girdle, which she claims can keep the man who wears it safe from death. Gawain likes the idea of possibly protecting his life, so he accepts the girdle. He is a hero here because he is very chivalrous to her. He is treating her respectfully, especially when telling her that he does not want the ring .
"...man that binds his body with this belt of green,/... No hero under heaven can hack him to pieces,/ For he cannot be killed" (90.)
