"Is my father a god? Am I the son of a god? Where is this divine energy coming from?"
His mother can't be a god because he would have sensed it. The divine energy is external not internal since it has to come from somewhere and it isn't from his mother. It could also have come from a completely unrelated god.
He was confused but not for long. The divine energy ignored him and began to unravel the fragments of order in his body. The ordered army of the law of order finally met its match. It was like a lever easily prying open floorboards. He got to work as soon as he saw the opportunity. The unraveling made it easy for him to tamper with the law of order and slot in the law of fire and light. Those two laws are also in perfect synchronization with the divine energy so the process went well.
