Summarize what happens in the lines below:
Wiglaf, Weohstan’s son saw his king collapsing, and showed his bloodline’s bravery and Geat-born grit. His fighting hand was singed as he dodged the dragon’s head, but he drove lower, spurning safety to spit the serpent’s stomach with his ogre-etched sword. With that blade in her belly, she couldn’t belch flame. Her fires sputtered. Now Beowulf, with his last strength, drew a dagger from his hip, a lethal hunting thorn, and dipped it into the dragon’s side, wounding her fatally: blade met body, a bleak and bitter fight. Together, these two slew their foe, courage conquering flight, and that duo, kin by blood and bone, did it side by side. Every warrior should step up to serve his lord, throw down regardless of odds. This was the last battle for the king, though, his final victory a grim one.
