I mean I would but here's a secret... I tricked you!
Ok if your going to kill me just do it!
....And then this happened!
When he found the Knight, he became nervous. The Knight swang the axe three times and Gawain got angry and demanded for him to just get it over with.
The Knight explained afterwords that he tricked Gawain. He told Gawain that he had been chilverous except for keeping the scarf from the Lady. But he only kept it to keep his life. It was a good luck charm.
Gawain went home and told the people his story. Everyone was shocked and in awe. And that is the story of "Gawain and the Green Knight".
