The time when Brandon had shot at the two of them, when he and Celine were training, he had come to know that although he was almost seven times stronger than any other normal human, that didn't mean that he was invincible in the face of the bullets.
Although he could currently get himself healed as long as he took the body strengthening solution, things wouldn't be the same if he was shot in the heart or on the head.
He had already had into the satellites and had managed to get some images of the situation where Nathan was. From the way that he had seen it, there was several snipers that would surely cause him trouble if he appeared.
That was the reason as to why he had decided that he was going to take care of them first. After they were going to be taken out, he would then face the rest of the people.
