The award ceremony went without a problem. Soon, Jane was called the leader of the Sur group. She gets awarded money, rare material, and access to rare skills/spells. Finally, Angus gets called at the end. He came forward and took one knee while bowing in front of King Leon.
One knee bowing is a gesture of allegiance and servitude. It means Angus recognizes and shows his respects to King Leon. Although Angus doesn't like to lower his head to others because of his pride, he is still someone who could bow to others if he finds they are worthy.
Angus knows King Leon's code of conduct and his burden to lead this big kingdom. They often bicker and fight each other, but deep inside, he truly respects King Leon. He also knew how big King Leon's responsibility was as the heart kingdom leader.
