In Sir Gawain and the Green Knight, Sir Gawain continuously proves his knightly virtues and code of honor. Chivalry includes bravery, honor, and courtesy. He proves that he is in fact a "real" Knight. He shows his bravery by shying away from nothing and no one. He proves his honor and courtesy to everyone he meets by showing respect to all whether he receives it back or not.

He seemed a brilliant leader, and could have been." (II, 677) Gawain knows all of this that on his travel he would be put to death, he still went on this final crusade, to his death with utmost bravery.
Sir Gawain also shows his honor often. In accepting the Green Knight's challenge he shows his honor to the whole court. Now, set on his crusade Gawain was to prove his honor to the Green Knight. Though many adversities he faced, he still went on "In God: he could have died a dozen times over" (II, 725) All to fulfill his
