Answer:
By risking his own life in order for Beowulf to be able to kill the dragon
Explanation:He constantly honors the code established between the king/lord and his followers, by fearlessly defending his lord without a second thought and in return the lord honors him with land and treasures.
This shows how Wiglaf is not only a fearless warrior but also a extremely loyal companion as he would risk his own life for his lord.
