Alex cares a lot about his son He knows he will not have the luxury of being normal due to the assassination attempts that have been made against the family. He wants him to be strong Trag, who just wanted his father to be proud of him, has adopted a very nihilistic view of life.

I will not explain what happened but, she got pregnant with him. Alexander, feeling betrayed, divorced her immediately. She felt humiliated and forbade their son to see his father. He grew up isolated with his mom, making him a bit socially awkward and lonely.

Leodagan was Traggan's only friend growing up and he cares deeply about him. In his own ways

Traggan has rarely interacted with Adra and does not consider her sis sister. Though he has nothing against her, he is envious of how Alexander cares for her. He feels bad for knowing his father... and everyone else is just using her.
