Throughout this passage, Wiglaf is presented as a model of loyalty. When all other warriors act like cowards, retreating to safety, Wiglaf decides to risk his life and stand by his old king in this last battle. He still doesn't act as Beowulf's equal, but he nevertheless offers him support, as his sworn warrior. Beowulf is indeed encouraged by this act and manages to kill the dragon while receiving a mortal wound himself.
