1. The first hunt is for a female deer. Bertilak does this by chasing it with dogs and blowing loud horns to scare it. There is very little difficulty for the hunters and they just slaughter everything. The lady sneaks into Gawain's room and tries to get him by using her charm. She never tries to trick him into doing anything and she is unseccesful. The second hunt is for the boar. The boar is very strong and hides, forcing the hunters to chase him down. Then Bertilak must get off his horse and kill the boar with a sword rather than arrows. This is much more dangerous for him. The lady goes in the second day and tries to flatter Gawain so that he will sleep with her. She offers herself to him but he resists and keeps himself pure. The last hunt is for the fox. The fox is very clever and eludes the hunters for a long time. It turns back and goes in circles to lose the hunters. Eventually they catch up and kill it, the kill was easy but the hunt was hard. The lady this time tries to trick Gawain today. She plays games and uses her charm. She doesn't really succeed in sleeping with him, but she does manage to mar his honor by giving him the sash.
2. Gawain is very honorable and is easy to respect in this situation. If I had been in this situation I doubt i would've been able to control myself as well as Gawain. He behaves well although I think he might've led the lady on too much. He seems to flirt with her too much and because of that he does lose honor by not giving the lord the girdle. He doesn't uphold his honor, if he had then the he would have given the lord the girdle and then not gotten his neck cut.
3. The climax is when the Green Giant swings the axe for the third time to chop off the head of Gawain. This is were he finds out if he has placed his trust in the right thing. Unfortunately he has been tricked and because he did not hold up his honor he was injured.
4. The girdle symbolizes paganism. It is something that is supposed to protect Gawain from death. He trusts in it more than he trusts in God in this story and that leads to dishonor. Had he trusted in God and not the girdle he wouldn't have been cut.
