Twin Dragons
Initially, Jason had been told to stay where he was, and simply observe the battle as a bystander.
The Queen wanted to demonstrate to him how powerful she was, and what kind of destructive power Demi Gods truly had.
In his opinion, the biggest reason for Queen Lilya to show him everything was that she wanted to finish cleansing the last continent as quickly as possible.
Simultaneously, she wanted him to see how powerful the Sacred Elvyr were, and what benefits he could obtain from them by staying in touch with them even after he finished what he had been requested to do.
It was only obvious that one wanted to get into the good books of an existence that had the talent to become a God.
Whether it was Jason's birthright, his talent, his willpower, the path of his fate, or simply the fact that the God's Halo was an indicator of a future God in the making didn't really matter in that sense.
