It has been a year since Gawain's incident with the Green Knight. Gawain is worried, but he knows that he has to go and meet the Green Knight. This is heroic because he is owning up to his promise, which is chivalry. Then, Gawain calls for his armor, in which the poet describes in great detail along with the description of the armor on his horse. The description of his armor gives the scene a very heroic tone, and this makes him a hero in this scene.
Gawain is leaving Camelot to go on his adventure to find the Green Knight. He is very heroic in this scene. When he leaves "fire [flies] up from the flinty stones." (46) He also leaves to a crowd of people from the castle who are "sick at heart" to see him leave "(46.)
"By Christ, it is evil/ That yon lord should be lost, who lives so nobly!" (46.)
Gawain heads out into the wilderness, traveling through Wales and England in his search for the Green Chapel. He encounters various enemies, including wolves, dragons, bulls, bears, boars, and giants. He always defeats his enemies. He sleeps in his armor and has nightmares. As the winter gets colder, he nearly freezes to death. For all of these reasons, he is a hero. He is enduring so much in order to get to the Green Knight in order to own up to his promise.
"I beseech thee Lord,/ And thee Mary, mildest mother so dear,/ That in some heaven with due honor I may hear Mass/ And Matins tomorrow morning: meekly I ask it" (49.)
On Christmas Eve, Gawain prays to Mary that he might find a place to attend Christmas Mass. He tells her that he is ashamed of his sins. He is a hero here because he is owning up to his sins . He " crossed himself and cried/ For his sins." (49)
Gawain found a castle buried deep in the woods after praying to Mary. He is portrayed as a hero a lot in the scenes where he is getting introduced to the castle. He is welcomed in by the porter of the castle, who invites him to meet the couriers and the lord of the castle. He is also welcomed by servants who hold " his saddle while he stepped down" from his horse (52.) These men then go on to stable his horse. Later "strong knights and squires" bring him into the hall and take his armor, shield and sword (52.) As he walks into the hall, he graciously greets "each gallant knight,/ And many proud men [press] forward to pay their respects." (52) They even give him an apartment and "rich robes" to change into, along with a feast (53.) He is obviously looked up upon in these moments, making him a hero.
The host invites Gawain to stay at the castle for three more days until New Years, which Gawain accepts. During this time, the host proposes a game to Gawain. During the day, he wants Gawain to stay at the castle and spend time with the two ladies. Meanwhile, the host will go out hunting with his men. At the end of each of the three days, the two men will exchange whatever they have won. Gawain accepts this game. Him accepting this is showing how he is a hero. He is promising to give what he receives, which is chivalry. He is also following what the host said to do, and this is to stay at the castle.
"Let us make a bargain/ That whatever I win in the woods be yours,/ And any achievement you chance on here, you exchange for it" (62.)
